Barry Allen (Arrowverse)

"Yeah, I might be in the suit doing all the running... but when I'm out there helping people, making a difference... you're all out there with me. Finally realized something, we were all struck by that lightning."

- Barry Allen/The Flash in Season One episode two.

"I think... part of being a hero is being able to see the good in people. So yeah, maybe someday in the future... even Thawne could change. Besides, if we don't believe in people, who will?"

- Barry to his daughter, Nora.

Bartholomew Henry "Barry" Allen, also known as The Flash, is the overall deuteragonist of the CW's Arrowverse series. He is the main protagonist of the 2014 CW series, The Flash and He's a scientist as the Criminal and Forensic Science Division of the Central City Police Department.

He's also the legal owner of S.T.A.R. Labs and is the secret leader of his own vigilante team, Team Flash. He is the leader of The Heroes team that includes Oliver Queen and Kara Danvers. He also makes guest appearances in Arrow, Supergirl and DC's Legends of Tomorrow.

He is portrayed by Grant Gustin, who also portrays his evil time remnant Savitar. Logan Williams and Liam Hughes played the character younger.

Early life
Barry Allen was born in 1989 to Henry and Nora Allen as an only child. At some point in his childhood he met Iris West who he became best friends with, and soon after formed a crush on her which her father Joe and both Henry and Nora were aware of. However Barry was also bullied by Tony Woodward and came to greatly resent him.

On March 18, 2000 when Barry was eleven years old, he ran home from school after getting into a fight. Though not being fast enough, his mother promised that he had a good heart, and his father was proud of him for winning the fight. Later that night Barry was comforted by his mother when he admitted he was afraid of the dark but she convinced him he wasn't afraid of darkness itself, just being alone in the dark and wished him sweet dreams. Later that night Barry was awoken by a commotion and went downstairs and saw his mother, surrounded in streaks of red and yellow lighting. Barry attempted to reach his mother but she told him to stay back and a midst the streaks Barry saw a yellow suited figure for a brief second, and his father told him to run. At that very moment however Barry suddenly found himself 20 blocks away.

Barry returned home in time to see his father being arrested by police, the former who told him not to enter the house. He entered, seeing Joe standing solemnly over a body. When he walked away, Barry approached the body and discovered, to his horror, that it was his mother. Following the ordeal, Barry was fostered by Joe and Iris. This also caused an inhibitor between Barry and Iris as growing up in the same household prevented their feelings (at least on Iris' side) to mature beyond sibling love.

Initially, Henry asked Joe to not let Barry see him. Not knowing this, Barry kept trying to run away to see his father at Iron Heights, and he was caught and stopped by Joe every time; at one point, Barry called him out for it, telling him that he wasn't his father and that he hated him. Eventually, Barry finally reached Iron Heights before Joe could stop him, and he finally came face to face with his father. Henry told him that he simply did not want Barry to see him in prison. Despite this, Barry begged for his father's release, insisting that the man in the lightning was who killed his mother, not Henry. Henry told him that he couldn't help him and asked that he be a good boy and let Joe raised him. Henry was promptly taken away and Barry became more accepting of Joe as his new guardian.

6 months after the murder Barry was still depressed and became grumpy towards everyone. Joe saw this and understood why he was acting angry because he didn't want to let the pain of the grief in, fearing his father and mother would be disappointed in him if he did. However Joe convinced him it's ok to let the pain in and Barry finally let himself feel the grief and cried, to which Joe comforted him and promised that he'd always be there for him.

In school Barry was relentlessly bullied by Tony Woodward. Joe noticed this and had Barry spar with Iris who easily beat him. Joe then told Barry that if he ever got into a fight he couldn't win that it was okay to run the other way. At the age of 12, Barry went to reptile camp, which was paid for by Joe. In high school, Barry attempted tryouts for the high school football team, however, failed horribly, making Joe swear to never talk about it again.

Barry had graduated from college majoring in two fields of science. It was with this skill that Barry was motivated by his mother's murder to study criminology, in the hopes of proving that his father was innocent. Barry admired many successful scientists but his idol who he was practically obsessed with was Dr. Harrison Wells, scientist who was in the midst of developing a particle accelerator that would open new fields of science and change the world. Barry came to idolize Wells so much he would have paid for his autograph and ready his autobiography twice.

Visit to Starling City
Years later, Barry arrived in Starling City. He wasn't able to initially get a cab as the driver pulled away, and he soon arrived at Queen Consolidated's Applied Sciences Division to investigate a mysterious break-in as a CSI from Central City with a connecting case, where he met Oliver Queen, John Diggle, Quentin Lance and Felicity Smoak (the latter whom he had an instant connection with).

He was set up in the division with Felicity's help, unknown to Barry, because Felicity believed that they should have used him as an asset seeing as forensic science. The two began talking, and Barry began speculating about The Arrow and his background, making incisive observations about why The Arrow wore green instead of black, the type of arrows he used, and how he theorized that The Arrow has partners, particularly someone who had a background in computer sciences; all of this unnerved Felicity.

Barry was astounded when Felicity asked him to help with a blood sample from an arrow she received from the police both by her "connections" from working for Oliver, and the fact that he was working the same case as The Arrow. During that particular part of their investigation, Felicity invited Barry to a Queen Consolidated function, which was actually a party at the Queen Mansion. However, before the results came in, his cover as a crime scene investigator working for the police was blown by Oliver just after he and Felicity began arguing over a news report about the mass particle accelerator.

It was revealed that he was just an assistant CSI and there was no connecting case in Central City. Barry explained what happened to him as a child, and how it had caused him to begin looking into cases with impossible circumstances, in hopes of one day proving one possible, therefore solving his mother's murder and freeing his father. He was later re-invited by Oliver as Felicity's plus one to come to his home where he was throwing a party for his mother. When there, he apologized to Felicity while they danced.

After the party, Barry was contacted by Singh and was told to return to Central City if he hoped to keep his job, and revealed the sedative used was ketamine, informing Felicity it should have been easy to track. He tried to catch the soonest train, though missed the last one of the night. He settled down in to the train station to wait for the next one in the morning, when suddenly he was hit with a tranquilizer dart to the neck.

When he awoke, he found himself in Oliver's base with Diggle watching him and Oliver lying on a table in full Arrow costume. Felicity approached him and asked Barry to save Oliver's life, who was not only poisoned with an unknown substance from the A.R.G.U.S. disaster bunker, but also had been beaten by the robber who had stolen the centrifuge from Queen Consolidated, raided the blood bank, and encountered Oliver as The Arrow while stealing large amounts of ketamine from the bunker.

Barry was able to save Oliver's life, which Oliver was not too pleased with at first, as they had revealed his secret without his permission. However, Barry eventually gained Oliver's trust. He recommended that a mask would be better than the green grease he used on his eyes as better concealment of his identity. Oliver later asked him if there were any side effects to the rat poison he injected in him, and Barry told him that it could cause hallucinations and heavy sweating. He then discovered that Oliver's hallucinations weren't from the serum, and that it was psychological. Barry soon after headed back to Central City.

The accident
On his train back to Central City, Barry encountered Martin Stein and the two discuss physics and Harrison Wells' particle accelerator and how it would change the world. After he got off the train, he soon headed back to work, arriving to a crime scene late. He was successfully able to identify the getaway car from the robbery and also grabbed a sample of some animal feces found on the ground, before heading back to his lab to examine the evidence. While processing the feces, he was greeted by Iris. Barry discussed the S.T.A.R. Labs particle accelerator, noting that it provided ideas that were far beyond their current capabilities of science, hence why he was so excited. Detective West approached right as the feces had processed. Barry described the results found, explaining that it had a chemical used only at four different farms around town, suggesting they check them out.

Following, Barry and Iris headed to the unveiling and switching on of the particle accelerator. Barry attempted to convey his attraction towards Iris, but she simply misunderstood it. They began listening to Dr. Wells who described how the particle accelerator would lead to a much greater future. As they were listening, a guy stole Iris' bag along with her laptop inside it. Barry ran after him, attempting to catch up to him, however the guy knocked the wind out of him and ran off (only to later get caught by Detective Eddie Thawne). At the police station, Iris and Barry mocked Eddie, a new transfer from Keystone City.

Later Barry headed to his lab, watching the news of the S.T.A.R. Labs particle accelerator, but as he watched it, it became unstable. The particle accelerator sent a shock-wave through the city, and only seconds later was Barry struck by a red bolt of lightning through a window in the roof. He was sent backwards through the already-charged chemicals and was knocked unconscious. A red flash of light appeared across his cheek, rising, and then faded away. He was quickly rushed to hospital, where he was kept on life support whilst in a coma.

For the following five weeks, Felicity Smoak visited Barry in the hospital while he was in a coma, and left only to help Oliver. Barry's heart constantly seemed to stop working, however it was concluded by Harrison Wells, who begun to visit him, that his heart was in fact beating too fast to even register. When Barry's condition began to worsen he was moved to S.T.A.R. Labs to be closely monitored and was frequently visited by Iris West. Barry was visited by his friends and relatives at the hospital frequently. When Iris came by one day, she received a static shock as she grabbed Barry's hand.

Becoming the Flash
When he woke up from his coma 9 months later, Barry met D. Wells, Cisco Ramon and Caitlin Snow. He learned of his coma and how it had been caused by the explosion of the particle accelerator. Much to their annoyance, Barry chose to leave, claiming that he felt normal. Barry went to meet Iris at her work, where the two embraced, Iris incredibly thrilled to see Barry awake and walking. As they talked, Barry noticed time slow down, then fasten back up again.

Iris grabbed her jacket, then they went to visit Joe at the police department. Joe was more than happy to see Barry, though he was called to a robbery at Gold City Bank. Detective Thawne followed West, also expressing his happiness at Barry's return. As they left, Barry noticed a rough detainee, who quickly reached for a police officer's gun. Before he could grab it, Barry sped over to him and back, stopping him from doing anything.

Freaked out by the incident, Barry promised to call Iris that night and left. Once outside, Barry noticed his hand shaking at an unbelievable speed, shortly followed by him accidentally almost running in to a bin at super speed, then breaking the back window of a cop car. Realizing the gifts he had, Barry went off running, testing out his super speed. Before long, he accidentally ran through the back of a van. Sometime later at an airfield, Barry met with Cisco, Caitlin and Wells. He put on a tight suit and got ready to run. Dr. Wells cautioned restraint, whereupon Barry began to run at full pelt.

Partway through, he began to remember the night of his mother's murder, specifically a ball of lightning with a man seemingly inside it surrounding his mother, and he crashed, fracturing his wrist. Back at S.T.A.R. Labs, they discovered that Barry's wrist had healed in under three hours, much to their amazement. Dr. Wells inquired as to what happened, and Barry explained what he'd remembered: a man somehow inside a ball of lightning. Barry raised the question that perhaps there were more people like him, but Harrison rejected the idea, claiming that Barry was unequivocally one of a kind. Following that, Barry went to meet Iris at Jitters.

He looked upon Iris and Eddie kissing, and they soon took a walk as Iris explained to Barry how the two of them had met, asking him to promise not to tell her father. As they talked, a police car involved in a car chase slammed on the brakes, leading to Barry pulling Iris out of the way as the car hit the wall under the bridge. As the other car raced by, Barry recognized its driver: the seemingly dead Clyde Mardon. Barry ran after the car, crashing through the side and entering. Before Mardon could get his gun out, Barry grabbed the steering wheel, making the car tumble on its side, on to its top. Mardon exited the vehicle, relatively unscathed and Barry quickly followed.

He called out to catch Mardon's attention, but soon the area was flooded with fog, apparently made by Mardon himself, causing a car to run in to the already overturned car, forcing Barry to speed to a nearby patch of grass for safety. Paramedics soon arrived, along with the police, including Joe. Joe scolded Barry for having Iris out in the open and Iris for having followed the danger. Barry took Joe aside, telling him of his belief that the car was driven by Clyde Mardon, who had apparently survived a plane explosion, also somehow gaining the ability to control the weather.

Despite various pieces of apparent evidence, Joe didn't believe him. Frustrated with Barry's seeming fantasies, Joe explained how his claims were impossible, including the ball of lightning with the man inside; he knew Barry's father was the murderer, as did numerous others. Having never asked for anything from Barry, Joe asked Barry to for once be realistic, to which Barry simply walked off, disappointed.

He returned to S.T.A.R. Labs, angry at Wells for lying to him about being the only one affected by the particle accelerator's explosion. Dr. Wells claimed to not be entirely sure, as there had been numerous amounts of radiation including anti-matter, dark energy and x-elements, all apparently theoretical prior to the event. Despite them only being theory up to that point, Wells claimed that Barry was proof otherwise. He went in to more detail, explaining that they'd been looking for more "meta-humans", a term they'd coined for people like Barry. Barry brought up Clyde Mardon, whom they had to stop before he hurt anyone again.

Wells cautioned Barry to keep himself safe, as Barry had the potential to unlock previously undiscovered vaccines, medicines and breakthroughs in science, yet he wished to put himself on the line and "play hero". Dr. Wells saw him as nothing special, just a boy who'd been struck by lightning. Upset by Harrison's statement, Barry called Oliver Queen, hoping to get some advice. He visited Oliver in Starling City, where he expressed that he believed Barry could save people, though in an entirely different way to The Arrow. As opposed to The Arrow's tough vigilantism, Barry could be a guardian angel to the people of his city, saving them "in a flash". As he speeds away, Oliver expressed his awe at Barry's powers. Barry headed back to Central City, to S.T.A.R. Labs. He apologized to Caitlin and Cisco, understanding that they'd lost things in the explosion, but there had been an increase in crime, presumed to have led from the creation of meta-humans. They agreed to help, and Cisco even suggested the use of a suit he'd made, initially for a firefighter, but believed it suited Barry well.

He put on the suit and raced to Mardon's farm, where they'd noticed an acute change in the weather. He saved Joe and Eddie, who'd come to investigate, after a piece of debris flew at them. With Mardon's tornado heading towards the city, with an increasing wind speed, Barry suggested that he run around the tornado in reverse in order to unravel it. Despite Caitlin and Cisco's belief that Barry might not hold up, he proceeded to run around it. Before he could run fast enough, Mardon knocked him away. Believing him to be too strong, Barry didn't think he could beat Clyde.

However, as he was about to give up, Dr. Wells began communicating with him. Despite acting selfishly, Wells expressed that he truly, deeply believed that Barry was special, that he could help stop the havoc he'd created. With the confidence boost, Barry was able to run fast enough, clocking just over 700 mph, ultimately unraveling the tornado. After being knocked to the ground, both Clyde and Barry stood up. Clyde proceeded to point a gun at him, claiming them to be the same, though Barry strongly disagreed.

Before he could shoot Barry, Joe intervened. The following morning, still at the crime scene, Joe and Barry discussed Barry's powers and Joe apologized, for not believing him and for also believing his father a murderer. Barry also promised not to reveal anything to Iris so as to keep her safe. Not long after, Barry visited his father in Iron Heights Prison, assuring him that he still believed in him, that he was incredibly proud to be his son. After that, with a lightning bolt symbol added to his suit, Barry ran through the streets of Central City, saving a man from crashing on his bicycle.

Early days and setbacks
Barry continued to save citizens throughout Central City, much to the frustration of Caitlin and Joe. At his day job with the CCPD, Barry investigated a strange robbery and murder scene wherein the surveillance footage showed one man, but evidence indicated that there were at least six present. He later made a casual remark that the perp's footprints were about the same size as those of Captain Singh's but was reprimanded for it by Joe, who reminded him not to tell Iris about his ability. Later, Barry went to Stagg Industries with Iris, where Simon Stagg was set to receive an award from Central City University. Iris was covering the event for her journalism assignment and needed Barry to help her with the scientific parts.

At the event, the armed gunmen responsible for the scene Barry had just investigated came arrived and was in the process of taking their valuables when a security guard attempted to stop them. Just before they could shoot him, Barry saved him and went after the robbers, only to lose consciousness along the way. After his fainting, this prompted the S.T.A.R. Labs scientists to investigate Barry's recent weaknesses. After a run at a "Cisco'd" treadmill, it was discovered that Barry had acute hypoglycemia, a condition that Barry developed because of his sped-up metabolism and could be remedied by a more extensive meal plan. Joe then arrived at the lab and called him out for his unnecessary heroics. Because of this, Barry lost confidence in himself and, face to face with Danton Black, the meta-human that infiltrated the Stagg event, he realized that he did not have the ability to really go up against them.

At this point, Iris was still trying to get Barry to tell her what was going on with him. Just when he had momentarily quit his association with Wells and the others, Iris revealed that her new journalism topic would be his alter-ego, who has been dubbed the "red streak" by citizens. Caitlin then called Barry back to S.T.A.R. Labs and told him of a way to defeat Black. Joe then arrived to convince Barry to go after him. Barry did and followed Danton to Stagg Industries, where he intended to kill Stagg once and for all.

With pep talk from those at the Lab, including Joe, Barry was able to isolate the real Danton from the hundreds of clones and put him down. When Danton momentarily regained consciousness, he attacked Barry only to miss and hit the window. Barry tried to save him from falling but Danton, not wanting to be saved, summoned up an extra hand to pull him from Barry's grip and fell, much to Barry's disappointment. Later, Barry commended the group at the lab, who then fully supported Barry's city-saving, even Caitlin, and made amends with Joe.

Barry went to the movies with Iris when Cisco and Caitlin informed him of a car chase. Using his speed Barry quickly stopped the robber and returned before Iris knew he was gone. The next day Barry and Joe investigated the death of the Darbinyan crime family. Noting that as the victims were poisoned with gas they would have all died at the same time, yet some of them had time to move. This led to Barry realizing that they were dealing with another meta-human who could control gas. At S.T.A.R. Labs, Joe brought up the topic of finding a suitable prison for meta-humans. Wells and Cisco decided that the particle accelerator would be the best place to hold them until they could cure them of their powers.

Caitlin, remembering the death of her fiancé Ronnie, froze in her spot. Seeing her distraught, Barry offered for Caitlin to help him run tests on the poison gas they'd procured. At Barry's lab the two talked about Ronnie until the DNA results came back, revealing that the gas inside the victims also had someone else's DNA. Hearing of the murder of Theresa Howard on the police radio, Barry left despite Caitlin pleads. Arriving at the scene, Barry found himself too late and angrily chased after the meta-human. Before he could fight him, the man transformed in to gas and forced Barry to inhale him. Rushing back to S.T.A.R. Labs, the team were able to painfully extract the gas with a needle.

Despite being told to rest, Barry went to talk to Joe and confide in him about his inability to save the judge. He went on to mention his temptation to break his father out of jail, though Joe reasoned that his father would simply be a fugitive, and despite his abilities, Barry would never be able to save everyone. Later Barry apologized to Caitlin for worrying her, only for Caitlin to reveal that what he had said to her were the same last words Ronnie said before he died. Barry decided to help her overcome her fear of walking into the particle accelerator. After finding peace, she thanked Barry and the two embraced. Wells and Cisco soon called them up and revealed that a sedative was also found in the gas.

Barry told Cisco to check if anyone was executed on the night of the particle accelerator, as the two chemicals were used when executing death-row inmates. They identified the meta-human to be Kyle Nimbus, a hit-man for the Darbinyan crime family, who turned on Nimbus, leading him to be arrested by Joe West and prosecuted by Judge Theresa Howard. Barry quickly suited up and headed to Iron Heights prison, saving Joe who was visiting Barry's father. Barry then went after The Mist, as Cisco proudly nicknamed him, defeating him by tiring him (meaning he would be forced to revert to his human form eventually). Barry later visited his father and confided in him they he missed his mother. Henry comforted him by telling him the story of how he learned to walk. Barry realized that to honor his mother he had to continue running, as he had always done.

Barry trained the speed of his mind by multitasking by playing a game of chess with Harrison Wells, a game of Operation with Caitlin, and a game of table tennis with Cisco. Barry defeated Cisco and Caitlin but made a mistake which caused him to lose against Wells. Soon after, they had an alert of a bank robbery, to which Barry responded to quickly. At the scene, Barry managed to unmask Leonard Snart, the leader of his crew. After a guard was shot, Barry quickly rushed him to St. Andrews Hospital and quickly returned to the scene for work. When Captain Singh noted that a guard said there were three robbers, Barry corrected him to four, though he quickly justified his reasoning as it had to of been a four-man job. After Singh sarcastically thanked Barry for his insight, Joe asked if Barry saw anything that could help the case, to which Barry told Joe he saw one of them unmasked. At the prescient, Barry quickly identified Snart to which he learned that Snart's father was a dirty cop. Later when Iris brought Barry coffee, Barry was told by Iris that she began a blog about The Streak. Barry failed to convince her to stop with the blog as it only brings crazies and trolls.

Barry was shocked when he saw Felicity in his office. Barry caught up with Felicity to which he learned Felicity listened to his entire conversation with Oliver on the rooftop. Barry showed Felicity his powers and brought her to S.T.A.R. Labs. When asked if they could trust Felicity, Barry told Cisco and Caitlin that she works with The Arrow, reassuring them. Barry showed his powers again, using the treadmill to which Barry attempted to show off by running backwards, though he failed. When Barry brought Felicity to Jitters, he was invited by Iris to join her and Eddie to Trivia Night and to bring Felicity. When Iris asks why Barry isn't dating Felicity who she claims to be the perfect girl, Barry states that they are only friends. At trivia night, Barry and Felicity answer a majority of questions correctly. Iris then pushed Barry to ask Felicity out again, assuming Felicity was very interested in Barry based on how she dressed. After Snart was spotted, Barry left and had Felicity cover for him, though she had no excuse that could work for him.

Barry arrived in time to save Joe and a few others but due to the fact he was struck by the cold gun when saving Joe, he was slowed down and failed to save a security guard. Barry later was furious at Cisco for building the weapon which caused the death of a man. Barry felt betrayed as he was never notified of such weapon, causing him to be unprepared. Barry quickly learned Cisco originally made the gun to be used on him, had he gone uncontrollable. After the team tracked Snart, Barry decided to take him on his own and turn off all communications. When Barry confronted Snart, Snart notes that Barry's weakness is his altruism always saving others, rather than go after the villain. Snart froze the wheels of the train, causing it to derail as he fled. Barry having no choice, managed to rescue all passengers though he was attacked by Snart. Before Snart could finish him, Barry was saved by Cisco, Caitlin, and Felicity. Back at S.T.A.R. Labs, Barry said his goodbyes to Felicity, though he later chased after her and hopped on her train. The two had conversations on relationships before sharing a kiss.

Barry was hanging out with Cisco, Caitlin, Iris, and Eddie at a bar where he discovered that because of his high metabolism he could not get drunk. Suddenly an explosion was reported at a building Barry raced over to see a window washer about to fall, thinking of no other way to save him Barry asked Cisco and Caitlin how fast he would need to go to run up a building. They told him that if he moved at extremely fast speeds he would be fine but must maintain his speed on the way down or risk serious injuring. Barry rescued the man but was seen by Iris. blurring his face so she couldn't recognize him he quickly left.

Later as police investigate Barry noted that he could find no bomb casing to Joe. Searching through the files using his powers Barry found some information that pertained to the incident. Back at the police station Barry was told by Joe to give the military everything they had on the case. Barry handed the files over but using his speed managed to snatch one file from them. Joe told him to consult with the crew at S.T.A.R labs. At the lab Barry told them of what happened. Wells was familiar with the general leading the investigation, Wade Eiling. Wells explained that he worked with Wade to develop gene therapies for soldiers while Wells was concerned for it benefiting civilians only for him to severe their partnership when he found out Eiling's plans for developing mind reading abilities for interrogation purposes. Cisco went through the army's digital records where they discovered the culprit was a woman named Bette Sans Souci, a bomb specialist for the army. Barry found Bette at her last known address however when tried to take her in contact with her caused his clothes to begin to detonate Bette told Barry to get out of his clothes before they exploded which he did just barley escaping the blast.

Back at Star labs Barry told a distraught Cisco about the suit and revealed to the others she was a meta-human. Joe came him and asked Barry why he didn't tell him Iris saw him the other night. Barry told him she caught him off guard so Joe told him to tell Iris to stop blogging about him. Barry begged Iris to stop but she refused claiming that he himself wanted to know to find out about the impossible since they were young Barry noted that she wasn't even putting her name on it, Iris told Barry to talk to her when he told her the truth of why he was being so skeptical. Cisco and Caitlin called and told him that Bette was spotted at the location of the surgeon who experimented on her.

Barry arrived just in time to save Bette from being captured. Back at Star Labs the others told Bette of how the Particle Accelerator explosion and how it changed her.As they examined her Caitlin discovered a tracked inside her graze wound when the army attacked her, leading Wade right to Star Labs. The others quickly got her got her out while Wells stalled Wade. Outside while testing her abilities Bette asked Barry if the others had tried to help him find a cure. Barry told her how a friend once told him that the bolt struck him for a reason and now because of it he can help people. Joe called and told Barry that Iris put her name on her blog. Barry confronted her as the Flash and told her to stop writing about him. Iris revealed that to him that she was writing to help Barry prove that the impossible does exist.

Barry arrived at Star Labs where the others revealed to him and Bette that curing her was at the moment impossible. Barry suggested that they join her but the others pointed out that Bette's powers were to destructive and could put them all in danger despite Barry pointing out she was the first meta-human they encountered who was not a criminal or a person to use their powers to hurt others. Back at his lab in the police station Barry met up with Joe. He told him that by visiting Iris as the Flash he found out that Iris was only writing about him to help. Barry pointed out that the only way to get Iris to stop was to tell her the truth claiming he told her everything only for Joe to reveal he been knew Barry had feelings for Iris since he was a child and noted that Barry has not told Iris his feelings about her. Barry claimed it didn't matter since she was already dating Eddie but Joe told him that went fate wants something to happen whether it be him getting hit by the bolt that gave him his powers or getting two people to fall in love it works things out.

Back at Star Labs the others told Barry Bette had left without saying where she was going. When they finally found her about engage Eiling and his men Barry rushed to her location before she could kill him. As Barry talked her out of killing Eiling the general shot her killing her. As her body began to detonate the others told Barry to get her remains out of the city. Barry asked them how fast he would have to go to run on water. The team guessed about 650 miles per hour but told him he must escape the blast once he dropped her. Barry did and just barley managed to outrun the shock wave.

Later as Eiling covered up the incident Barry expressed disappointment, as Eiling had killed Bette in cold blood right in front of him and yet they could do nothing to him. Caitlin tried to comfort him telling him that running on water put him in interesting "company". Back at Joe's house Barry told Iris about his situation with Bette without telling her the specific details and asked her one more time to stop writing about the streak. Iris again refused forcing Barry to tell her that they should not talk to each other for a while.

Later Barry visited Iris once again as the Streak and tried to convince her to stop writing about him. However she ignored his request and instead tried to find out more about him. She then asked what she should call him with Barry claiming anything would be better than "the Streak". Their conversation was cut short when they heard sirens. Rushing to the crime Barry saved a kid who was about to get ran over by the culprit. Cutting the criminal off, Barry discovered he was a meta-human when the man rip the door off of the door of Humvee he had stolen and threw it at him. Barry dodged this and attacked the man, only for his skin to turn into a steel like substance which resulted in him injuring his hand and the man brutally back handing him. Beaten Barry escaped but not before the criminal told him that he was "born to take a beating" a phrase that seemed familiar to him.

Rushing back to S.T.A.R Labs Barry passed out on the floor. Caitlin examined his injuries and told him he had various fractures, a concussion and a bruised spleen the injuries being so severe to the point that Caitlin told him even with his healing abilities it would take a couple hours for him to recover. Barry then told them about the meta-humans abilities. Barry then asked how he was gonna fight a man made of steel. Dr. Wells and the team assured that they would find a way. The next day Barry reported to the Central Police Department, where he confirmed with Joe that the metal man was indeed a meta-human.

Joe told Barry that he was putting him and Eddie on the case so that Barry could explain to Eddie what he saw. Barry then went to see the Central City District Attorney. The DA identified the "man of steel" as Tony Woodward. Barry recognized the name. Woodward was a former classmate of Barry and Iris’, who bullied Barry throughout his childhood. After the meeting, Barry and Eddie ran into Iris. Eddie asks Barry what’s going on between Iris and him, not knowing that Barry was avoiding Iris but Barry told him everything was fine.

At S.T.A.R. Labs, Barry was introduced to a girder dummy built by Cisco so Barry can learn the right speed to take down Tony Woodward. Barry was easily defeated and dislocated his shoulder in the process. Shortly after, he was called by Eddie who had found the missing Humvee. Barry responded and as he arrived, Eddie recommended that he should get a car. Eddie then asked what's happening between him and Iris again where Barry revealed they had a fight. Barry and Eddie then headed to Rusty Iron Ale Brewing Co. after suspecting he had dropped by there due to the kegs in the trunk. After questioning a few men at the brewery, one man ran where Barry and Eddie chased him. Barry ran in front of the two, where the man punched Barry though it slowed him down enough for Eddie to take the man down. They then learn that Tony supposedly died in an accident though they revealed to the man that he lived. Barry visited Iris at Jitters again where he told her that Tony is an example of why she should stop blogging about him. As the cops arrived, Barry ran off to Tony's hideout.

Barry was easily defeated by Tony and rendered unconscious. After he was brought back to S.T.A.R. Labs, he was yelled at by Harrison Wells who reminded him that they were still finding a way to stop him. Barry was then told that they had found a way to stop Tony and that is to hit him at 837 mph. At the precinct, Barry and Eddie discussed being victims of bullying as kids. While blowing off heat using a punching bag. They were soon told that Iris was missing where the two quickly rushed down. After learning a fire alarm went off at his old elementary school, he quickly realized that's where Tony and Iris were. Barry fought Tony but was once again defeated. Barry then ran away from the school, 5.3 miles exactly. Barry then ran back towards the school, breaking the sound barrier and knocked Tony down. Barry then greeted an incarcerated Tony, revealing his identity and told him that the particle accelerator made them who they truly were.

After walking away from the makeshift prison, Barry celebrated as he had finally had his revenge on Tony. Barry then greeted Iris at Jitters and the two reconcile. When Iris told Barry more about "The Streak", she told him how he comes and goes in the blink of en eye where Barry interrupted her saying he does it in "A Flash".

Barry went for an early morning coffee run at Jitters, though a trainee was working that morning. After a woman complained about it, Barry sped past and got everyone their coffee and left a large tip for the trainee. As he left Jitters, a man grabbed him and asked for his wallet. Barry laughed at the man, as he chose him out of everyone else in the city. Barry proceeded to take a majority of the mans clothes off and brought a police officer as he ran away. Barry later was called to a crime scene where a man was burned to death. Joe said Barry had to ID him though Eddie asked how Barry was going to do so with the mans face melted off. Barry then bragged about his "mad skills". Barry then brought the photo of the man to S.T.A.R. Labs, where they managed to ID the man as Casey Donahue. Shortly after, the mans ID was used at an electrical plant, which Barry quickly responded to.

When Barry arrived, he encountered Farooq Gibran, a meta-human who has the ability to drain electricity. Barry made a few attempts to avoid his attacks though Barry was soon struck by Farooq. Barry later tried to run away, though to his surprise, he had last his super speed. At S.T.A.R. Labs, they had tested him on the treadmill, though to everyone's surprise, Barry ran slow for a normal person. Barry warned Barry about the meta-human who siphoned his abilities and killed the man. Barry later bumped into William Tockman at the precinct, who had complimented him for his watch. At S.T.A.R. Labs, they managed to identify the meta-human who shortly arrived at the lab, demanding to see Harrison Wells. Wells shortly told Barry that they could try jump starting him to regain his speed which Barry quickly agrees to. When Farooq broke into the lab, Barry tried to talk sense into him but Farooq only struck Barry. Cisco managed to close the doors to hold Farooq off for a short while.

Barry and Caitlin then went to the treadmill to jump start his powers. When Cisco turned the power back on, Caitlin was hesitant to follow through as she was afraid he would die. Barry told Caitlin that if she doesn't follow through that they would all die. When Caitlin made an attempt to jump start Barry, though they would learn that it had failed. Barry and Caitlin then witness Tony get defeated by Farooq. Barry asked what he was doing outside of the prison where Tony reminded him he never steps away from a fight. Tony then told Barry and Caitlin to get out as Tony died. Barry was then furious at Harrison, who had used Tony to buy some time. They then noticed that Barry's cells were still regenerating though Barry still didn't have his speed. Cisco and Caitlin then believe he has yet to regain his speed is because it's mental and doesn't believe enough. When they made an attempt to escape the lab, they were attacked by Farooq. Harrison then finally faced Farooq.

When Farooq attacked Harrison, Barry finally believed enough to regain his speed and save Harrison. Barry faced Farooq once more but this time he has connected to his powers and the energy overwhelmed Farooq, killing him. Barry then rushed to the precinct, worrying that something had happened to Iris. He was relieved when he saw her safe in Joe's arms. After they locked up Farooq's body, Caitlin noticed that Barry's cells were regenerating faster than before. Barry payed Eddie a visit at the hospital. After Iris left to grab a coffee, Barry briefly left and had a conversation with Iris as the Flash. Barry then told Iris he would never be late again and that Iris is worth being on time for. Barry then ran off and returned to Eddie's hospital room.

Barry arrived at a bank that Roy Bivolo was robbing, only to find everyone attacking each other. Barry managed to save a man from being shot as everyone began to stop attacking. When Joe and a few other police arrive at the scene, Barry suggested to Joe that the people were "whammied". At the precinct, Barry learned that Eddie finally believed the Flash's existence though he learned Eddie believes he's a menace. Barry proceeded to steal Captain Singh's lunch as he went to S.T.A.R. Labs to discuss the new meta-human. Shortly after, Iris called him out through her blog. Before Barry left, Caitlin told him not to get involved in Iris and Eddie's relationship as he would be responsible for their breakup.

When Barry arrived at Jitters, he told Iris his name was Ralph. Barry was warned by Iris that Eddie was pushing to get him behind bars. Barry managed to get to the storage facility Roy was hiding at before Joe and two other police officers could be killed. Barry was then greeted by Oliver, who had arrived in time to injure a "whammied" police officer. Barry then raced to the barn Oliver, Felicity, and Diggle were hiding at. When he arrived, he bragged how he gave Oliver a half an hour head start, yet still beat him. Barry asked the three what they were doing in Central City where he learned they were investigating a homicide which possibly connected to Central City, due to the material of the boomerang used to kill. Barry suggested that the two teams should work together, though Oliver refused as he didn't want anymore people in on his secret. Barry then carried Felicity and took her to S.T.A.R. Labs as she volunteered to go help. Barry was later told by Harrison and Joe not to trust Oliver as they feared he was too dangerous.

The following day, Barry met up with Oliver and Felicity at CC Jitters, where Barry learned that Oliver had helped get the name of the meta-human. Barry was then asked by Iris how he knew Oliver Queen. She then sarcastically said that Oliver's arms were twice the size of his and told him that Oliver was on her top 3 cheat list. Barry was then glad when Oliver decided to work along with him. The following day, Barry arrived late for the training, despite his speed. Barry was told by Oliver that he always ran in blind and he has a lot to learn. Barry was told to run a distance and run back where he'd get shot by an arrow where Barry told Oliver he wasn't going to be shot. Barry proved him wrong by catching the arrow though he was struck in the back by 2 bolts which Oliver had set up. At the precinct, Barry was told once again not to trust The Arrow, though Barry defended him, saying he's the reason they had Bivolo's name. Barry then decided to cut off the partnership and go after Roy himself. Barry was whammied by Roy but he believed there was no effect on him. Barry proceeded to bring up Ronnie in front of Caitlin. He later met up with Oliver where he told him that he believed Oliver was jealous of him. At the precinct, Barry lashed out at Captain Singh.

Later on, Barry attacked Eddie and threw him out of Iris' car. As he was about to beat Eddie, Barry was hit by a trick Arrow from Oliver. Barry then pulled the rope from the arrow and dragged Oliver down an alley. When Oliver fired two arrows, Barry dodged them, believing Oliver had missed, though he failed to realize there was an electricity box behind him. Oliver then injected Barry with two thousand milligrams of horse tranquilizer, though his metabolism burned it all off. Barry then ran circles around Oliver and as Oliver used one of his arrows to get on the roof, Barry reached the roof first and knocked Oliver down.

Barry then dodged a few hits from Oliver before punching him several times. Barry then caught two arrows which Oliver had set up to his motorbike. Barry was then shot in the leg with a flechette and then held by Oliver as Joe and Harrison arrived to reverse the effects from Bivolo. Barry and Oliver went on to take down Bivolo and look him in the prison in S.T.A.R. Labs. The following day at Jitters, Barry apologized to Oliver for his actions and his words, but was then told by Oliver that guys like them can never get the girl because of what they do. Barry visited Iris at Jitters though he learned Captain Singh has called the task force to bring him in. Iris proceeded to tell him she doesn't want to see him again after what he did to Eddie. Barry then ran off into the night.

Barry arrived in time to intercept two boomerangs from striking Oliver. Barry ran to the arrow-cave and performed the salmon ladder at super speed in front of Caitlin and Felicity. Barry then stated the salmon ladder made him hungry for sushi, which he quickly grabbed before rushing back. When Barry returned to the arrowcave, he had blown his identity to Lyla Michaels, to who he thought was Diggle's wife. Barry offered to help with the case, though Oliver told him that things are a lot different. Barry told Oliver that he had begun to approach cases more carefully rather than just running into them.

Oliver then accepted his help and told Barry they needed to reassemble the boomerangs to which Barry did swiftly. Barry and Oliver visited Quentin Lance where Quentin had forgotten has name and believed it to be "Bart." Quentin also believed that Barry was hit by a bus, rather than lightning, though Barry corrected Quentin. Barry asked Quentin about Klaus Markos where he learned enough information to track Klaus down. Barry was later surprised that Oliver was part of the Bratva, where Oliver told him that he's no longer a member. At the Bratva's hideout, Barry managed to subdue the members before Oliver arrived. After Oliver tortured Klaus, Barry brought Klaus to the Starling City Police Department and cuffed him to a drawer. When Barry returned, he admitted that he should have listened to Harrison Wells and Joe West. When Oliver told him that Starling City isn't always sunny and that he had friends and family murdered, Barry interrupted Oliver, saying he watched his mother get murdered also. Barry then told Oliver that he doesn't use his own personal tragedies to torture whoever pissed him off. When they believed they had tracked Digger Harkness, Barry and Oliver arrived at the warehouse, though they realized that they were played. When they returned, they found Lyla in critical condition where Barry rushed her to Starling General Hospital.

After Oliver blamed himself, Barry reassured him it wasn't his fault. When Oliver told Barry that everything he had been through taken away his humanity, Barry told him his humanity is what got him through everything. Barry and Oliver arrived later arrived a the train station where they had tracked Digger. Digger told them that they can stop him, or 5 bombs from detonating. Barry left to defuse the bombs while Oliver dealt with Digger. When Barry arrived at the first bomb, the team quickly realized that the bombs are linked and if one is defused, the remaining will detonate. Cisco told Barry that he needed to cut all 5 wires at the same time though Barry reminded him he wasn't Multiplex.

Barry then quickly grabbed Felicity, Caitlin, Roy, and Cisco to the other four bombs where the five of them managed to cut the wires simultaneously and stop the bombs from detonating. At the arrow-cave, Barry was surprised when he had a mannequin set up for a future team-up. When Oliver said he will still be calling the shots, Barry told him that they'll see about it. Barry and Oliver then went to a warehouse to settle once and for all, who would win in a fight. Before the dueled, Barry told Oliver that he could still inspire people, but as Oliver Queen. Barry managed to catch two arrows from Oliver before charging towards him and dodging multiple arrows.

Barry visited the West household for Christmas. When he set up the Christmas tree using his speed, he was told to remove what he had added as the only red suited man Joe wanted to see in the house was Kris Kringle. Iris shortly arrived with egg nog using her grandmother's famous recipe. Barry and Iris shortly exchange gifts where he gave Iris a replica of her mother's wedding band. Iris gave Barry a microscope which she thought was lame but Barry claimed he loved it. They were shortly interrupted by Eddie who joined them for tree trimming. Barry went to S.T.A.R. Labs where he brought the team gifts as well as Grandma Esther's eggnog. After an attack at Mercury Labs they discovered it was the work of the man om yellow.

Barry quickly wanted to go after him but was told by Joe that the speedster took all the evidence and threatened to kill Iris. At the precinct, Barry had memories of the night as he looked upon his bulletin board. He was visited by Iris who had been calling his name multiple times. Iris told Barry that Eddie had asked her to move in and she said yes. She then asked if Barry had feelings for her as Eddie was under the influence that he liked her. Barry quickly denied the suggestion. As Iris left, Barry sulked to himself but moments later saw the man in yellow, the Reverse-Flash, watching him just across from the precinct. Barry chased after Reverse-Flash and begging to know why he killed his mother, but Reverse-Flash told him if he wanted to know he'd have to catch him. The two race down towards a stadium where they battled though Reverse-Flash quickly defeated Barry.

Barry asked Reverse-Flash who he really was but the man claimed Barry already knew who he was, that they had been fighting each other for years. As Barry tries to fight back Reverse-Flash subdued him and told Barry it was his destiny to die at his hands, just like it was mother's. The following day, Barry told the team about what had happened. After Barry believed he couldn't catch him, Wells reminded that force fields are impervious to speed. Barry and Joe are visited by Tina McGee at the precinct who brought an unsigned warrant. Barry blackmailed Tina into giving them the tachyon prototype within the hour. Barry was then told by Barry that it's best for him to stay away while they capture the man in yellow.

Barry argued that it's his fight though they still shut him down. Barry visited his father and told him that he had found the man who murdered Nora. When he apologized for failing to catch the man, his father reassured him that it wasn't his fault. Barry was then told to stop pursuing that man as everything that happened to Barry was influenced by the murder. His father noted that he had given up the chance to be with Iris because he was too consumed with what happened. His father then told Barry to not let the man take anymore from him. Barry then went to visit Iris and confess his feelings, leaving Iris in tears.

Barry received a text from Caitlin that Reverse-Flash was attacking S.T.A.R. Labs. When Flash arrived he attacked Reverse-Flash though was quickly defeated again. Before Reverse-Flash can kill him however Flash is saved by a seemingly alive Ronnie who quickly fled shortly after. Back at the precinct, Barry and Joe recount the early days of Barry moving in. Joe claimed that Barry changed the atmosphere of the house and asked Barry to move back in. They then return to Joe's home for a Christmas gathering where he gave his best wishes to Eddie and Iris.

Upset he couldn't stop the Reverse-Flash in their last encounter, Barry trained harder. He had Cisco use a drone to fire ammunition at him, all of which he evaded. He then had Cisco fire a missile, which Barry successfully grabbed and threw towards the drone. Shortly after Snart re-emerged, Barry quickly realized Snart was setting a trap for the Flash. Barry vowed to take Snart down but Wells told Barry to set his priorities straight and focus on taking the Reverse Flash down. Barry went to Joe and told him he was going to focus on the Reverse-Flash and left Snart to Wells and Cisco, much to Joe's dismay. At S.T.A.R.L.A.B.S., after Caitlin brought up how Ronnie brought her scuba diving, Barry realized Firestorm wasn't a word but indeed an acronym.

After Leonard Snart and Mick Rory steal the Fire & Ice painting from the Ratahway's, many of the CCPD were injured and Barry admitted to Joe he should've listened and focused on the current situation. Wells apologized to Barry for pushing him to focus on the Reverse-Flash but Barry told Wells he made the decision on his own. After Snart and Rory made their public address to the Flash, Barry goes after them, making himself public for the first time. Though Snart and Rory get the upper hand at first, Barry realized in order to cancel the two's weapons out, he had to move slower. When Leonard told Barry he won this time, Barry responded that there won't be a next time. The following day, after Iris had moved out, Barry moved back in with Joe.

With the assistance of his team, Barry took down the Royal Flush Gang with ease. When he returned to S.T.A.R. Labs, the team took a group photo. After Wells was attacked by Hartley Rathaway, Barry went over to his mansion. When he noticed the shatter of the glass, he realized it couldn't have been a teenage prank. At his lab at CCPD, Barry demonstrated how Hartley likely used some sonic technology when he attacked Wells. After Eddie reported an attack on Rathaway Industries, Caitlin called Barry but Barry told Caitlin he already knew why she was calling. Barry quickly took down Rathaway, who told Barry he can hear Cisco, Caitlin, and Wells through the radio waves.

After Wells admitted he knew the chance of failure of the particle accelerator, Barry told Wells he owed Caitlin and Cisco more than an apology, as they stuck around when everyone abandoned him. Later that night, Barry and Iris had a coffee at Jitters discussing how people they admire aren't who they seem to be. When Hartley broke out of the prison, Barry rushed to S.T.A.R. Labs though Hartley had left by then. When Hartley attacked the Keystone Cleveland Dam, Barry rushed over and arrived in time to save a woman who Hartley threw off. Hartley used the data on Barry's molecular scans to stop Barry once he was disarmed. Hartley was then stopped after the team hacked into the frequencies after the cars at the dam to send out waves powerful enough to stop Hartley. When Wells told Barry he wished to regain the trust of the team one day, Barry told him he already had.

Barry saved a couple from a burning car, Cisco told Barry he couldn't be mad for dirtying his suit, to which Barry asked when he could start calling it "his" suit. While Barry was investigating Clay Parker, he was greeted by his father. When Barry brought the DNA samples to S.T.A.R. Labs, they realized Shawna Baez was also involved. Barry and Caitlin discuss how they both don't have much of a social life where they were interrupted with a sighting of Shawna Baez and Clay Parker. Barry rushed to the scene and was shocked when he learned Shawna can teleport. He was shot at in the neck by Clay Parker but managed to stop the bullet, though the two escaped. Barry stopped by to help Iris with a report, though she already had plans with Eddie. Barry then decided to drop by a south-side dive bar with Caitlin to check if Shawna and Clay returned to old habits.

After Caitlin had a few drinks, she walked up to the stage drunk and called Barry out to join her. The two then sang "Summer Nights" where Caitlin was shocked Barry could sing well. After their duet, Barry was greeted by Linda Park, who offered him her phone number. Barry then took Caitlin back to her apartment and put her to bed. The following day, Barry teased at Caitlin for what happened the night before. Barry was called and told that his father was beaten by Julius. Barry asked who attacked him and went after Julius. Barry broke Julius out and told him he wouldn't return him to prison, causing him to face more time if he didn't give him Clay and Shawna's next heist. After Barry was told they were in St. Louis, Barry decided to leave Julius out for beating his father.

While chasing Clay and Shawna, Barry busts out all the lights in the tunnel they were in, disabling Shawna's teleportation abilities and locking her in a one way glass. Later, Barry decided to call Linda Park and asked her to go on a date. Barry gave Iris information on Clay Parker to use for a report for the Central City Picture News. He then picked Linda up and the two go for a date. That night, Barry went back to Iron Heights to check on his dad. When Henry began putting the pieces together that Barry was the Flash, Barry claimed he would've told his dad if he was the Flash. Barry was then told that the world is dangerous and told to be careful and that his father was proud of him for saving many lives.

Barry took Linda on a dinner date at a Mexican restaurant. While Linda went to wash her hands, Barry was notified of a robbery at a convenient store and quickly settled the robbery. The following day, Barry had another date with Linda but had to end the date early after Wells and Caitlin spotted Firestorm. Barry tried to stop Firestorm and told him they could help but Firestorm attacked Barry and flew off. Barry and Caitlin then tried a different approach, bring Martin Stein's wife along this time, which Martin finally agreed to get help.

Linda called Barry to break up with him as she felt he didn't care enough in the relationship as he often ran off and made excuses. Linda told Barry that it's hard to date someone new when you aren't over someone and understood. Barry went to ask Iris why she told Linda she had feelings for her still and told Iris he no longer had feelings for her. At S.T.A.R. Labs, the team learn that Ronnie and Martin could go nuclear and level the entire city, unless the host body was killed. Barry went to offer Ronnie/Martin some pleasantries though Ronnie told Barry he overheard the conversation.

Barry went to Central City Picture News and told Linda he was going to eat a ghost pepper if she didn't agree on another date. Barry took a bite after she believed he was bluffing and Linda agreed to go on another date and offered him some milk. Barry returned to S.T.A.R. Labs and the team decide to use a quantum splicer on them two separate but learn Martin had left already. Barry and Caitlin rush over to Martin and the two told Martin that they have a way to separate them.

After they got to safety, Caitlin worried they were exposed to radiation, though Cisco informed them there were none. They went back and were pleased when they learned they successfully separated and took them back to S.T.A.R. Labs. Barry was contacted by Joe and was informed what he learned with Cisco the previous day. They brought the news to Wells who told them time travel is indeed possible. Barry then went to ask more about time travel with Martin Stein who suddenly had a panic attack when General Eiling attacked CC Jitters. Barry rushed over to stop Eiling but the latter used kinetic needles to stop Barry. They later learn that Martin and Ronnie are still connected.

At his home, Barry asked how Joe knew who's blood sample to match and was told that Joe asked Cisco to match the sample with everyone who worked at S.T.A.R. Labs. Barry then told Joe to not worry as he was sure Wells had nothing to do with his mothers murder. After Martin was captured, the team track him down and Barry, along with Ronnie go to rescue Martin. Barry was hit with a weaponized phosphorous and began running in circles to burn it off. After Eiling had the upper hand, he prepared to kill Firestorm though Barry stopped Eiling in time and Barry returned to S.T.A.R. Labs with Firestorm. Later, Barry told Joe that when the time came, he wouldn't fail like he believed he had in the past and he would save his mother.

After Barry loses a USB drive containing information on various crime scenes and searches for it at S.T.A.R. Labs with little success, but his attention was quickly diverted when Cisco told him of a possible metahuman, Mari McCabe whom Cisco nicknames “Vixen”. However Cisco also informs Barry that Mari was currently living in Detroit and not knowing what to expect Barry went to Oliver for help and the two headed to Detroit to confirm whether or not she is a threat. Flash and Arrow arrived at the house of Mari’s foster father Chuck but when she saw the vigilantes she immediately ran and they gave chase.

Flash gave chase to Mari whose speed was just as fast as his and asked her to stop but she refused and displayed incredible strength caused Flash to fly back several blocks, but eventually resumed the chase with Arrow. Mari then displayed the ability to run up a building forcing Flash and Arrow to take the fight to the rooftops. Despite the combined efforts Mari continued to outrun Flash and dodge Arrow’s shots, even crushing his arrows with her bare hands. Mari also displayed the ability to camouflage but Arrow attempted to restrain her with a jettisoning arrow but she outran it, only to slip off the side of the building but then displayed the ability of flight which highly impressed Flash.

As Mari attempted to fly away Arrow convinced her to come back as they just wanted to talk, though Flash wanted to handle the talking claiming to be better at it but Arrow simply reminded him he just puts meta-humans in the pipeline. However Mari shot down Flash and Arrow’s claim that she was a meta-human claiming that she wasn’t in Central City when the particle accelerator exploded, which Felicity was able to confirm. Though Flash was unconvinced Arrow offered their help to Mari to understand what she can do but she turned them down as she was uninterested and warned them that if they ever showed up at Chuck’s house again, she’d kill them and flew off.

Ignoring Mari's warning Flash and Arrow returned later to her house, where they discovered she'd become a vigilante herself, and Arrow questioned her intentions to take on Detroit's criminals without training. However Mari convinced them to let her try things her way for a while and Arrow agreed and wished her luck as Flash reminded her they could still help if she needed them to. After Mari asked if they had an idea of a name for her Flash told her that Cisco had been calling her Vixen, and he quickly tried to cover up mentioning Cisco causing Arrow to ask if Barry and Felicity were separated at birth. Arrow also learned that Flash kissed her causing him to speed off in worry.

Barry took Linda bowling where they bumped into Iris and Eddie. The two join them but later, Eddie and Barry were called after a silent alarm went off at the Central City Morgue. Barry ran ahead and investigated the crime scene prior to returning as his CSI job and on his way, he noticed another Flash running beside him. After listening to a recording, they learned that it was Mark Mardon who attacked the Morgue.

The following day, while Barry and Joe were discussing over a drive, they were attacked by Mark Mardon, though Barry got Joe to safety in time. Barry and Iris later went to CC Jitters where the latter told Barry that she suspects Wells had to do with Stagg's murder. Barry told Iris that Wells is a great man and she won't find such a story. Barry later told Cisco and Caitlin from what he heard from Iris but still denied the fact that Wells had involvement in Stagg's disappearance. After Mark attacked the precinct, Barry ran over in time to stop Mardon with the Wizard's Wand, though Mark escaped. The following day, Barry dropped by and conversed with Mason Bridge about Harrison Wells.

Barry asked Mason what evidence he had on Wells and was told to read about it like everyone else. After Joe was kidnapped and held hostage by Mark Mardon, the latter called Iris to meet him at the waterfront. Barry went to help Iris. Linda stopped by the precinct to talk to Barry, though Barry told Linda there was something more important, though not what she thought was going on. At the waterfront, realizing the danger, Barry told Iris to get out and get to safety, though Iris confessed her love for Barry. The two share a kiss before Barry revealed his alter-ego to Iris. To stop Mark Mardon's wave from destroying the city, Barry ran back and fourth the seawall to create a barrier of wind and doing so, he accidentally traveled back in time as he watched his past self run towards the morgue.

At the morgue, Barry was confused at what was going on, quickly solving everything. At S.T.A.R. Labs, Barry finished off everyone's sentences and Wells quickly realized that Barry had traveled back in time. Wells then warned Barry to not alter any events, big or small as it could cause a cataclysm. Ignoring Wells instructions, Barry tracked down Mark Mardon and brought him to the S.T.A.R. Labs particle accelerator prison. Wells told Barry that even though he may have saved many lives, time would find a way to repair itself. Barry ran as fast as he did previously in an attempt to go back once again, though to no success.

At Central City Picture News, Linda told Barry that she knows he still had feelings for Iris and broke up with him, though wished him luck with Iris. Barry then told Mason he knew he suspected something wrong with Wells. Later that night, Barry and Cisco grab a drink but Barry ended up leaving Cisco with Lisa, unknown to him who she really is. The following day, Barry confessed his feelings to Iris, though to his surprise, she didn't feel the same way. After a report of Snart and the Santini crime family casino, Barry rushed over and held Lisa hostage. Snart told Barry to let her go as he told Barry he has Cisco hostage. After the two left, Barry returned to the labs as a CSI where he was punched by Eddie for trying to win Iris over earlier. The following day, Cisco showed up at S.T.A.R. Labs and quit, feeling guilt for revealing Barry's identity.

Barry told Cisco that he shouldn't feel sorry but Cisco still felt the guilt. Barry and Caitlin later realize the casino wasn't the target but a way to trigger a money transfer. Barry chased after Leonard, Lisa, and Mick and captured Leonard. Barry told Leonard he could lock him up for good but Leonard told him then there would be no way of stopping his broadcast of him revealing Barry's identity. Barry told Leonard that if he was good as he claimed he is, he shouldn't need to kill. Barry then told Leonard if he hurt anyone close to him, he would go after him, no matter who Leonard told his secret to. At Jitters, Eddie apologized to Barry for hitting him and learned that Caitlin told Iris and Eddie about his "lightning psychosis". Barry later went to ask Wells about Stagg but before he could ask, he saw a report of Mason Bridge missing. He later called Joe and admitted that he was right about Wells.

Discovering Wells' true identity
Barry and Joe discuss over Wells and while Barry believed he could be the Reverse-Flash, Joe told Barry that the blood at the house didn't match his. Barry then rushed over to a terrorist attack by Axel Walker, who claimed himself as the Trickster. They learn that Axel is a copy cat of James Jesse, who had killed 10 civilians and 2 cops prior and now facing life sentences at Iron Heights. Barry and Joe head over to Iron Heights where James Jesse told them Axel likely found his lair. On their way out, Barry stopped by his fathers cell and told him he has gotten closer than he had before in investigating his mothers mother.

Iris later called the Flash to ask for help for the investigation on Mason Bridge's disappearance. Axel then made an address that he had planted a bomb somewhere in Central City. When Barry couldn't find the bomb, Wells told him it was a trick but Barry refused to listen. As Barry kept looking, Wells theory was indeed correct as Axel broke James Jesse out and took Henry Allen hostage. Upset his father is held hostage and possibly killed, Joe was comforted by Barry and while the latter no longer trusted Wells, Joe told Barry it didn't matter why Wells was helping and the only thing that mattered was that he did. After they tracked down the Tricksters, Barry ran over but Axel planted a kinetic bomb so if Barry didn't run over 600 mph, the bomb would go off. Barry was told by Wells to phase through a wall but Barry refused to listen. Wells told Barry to feel the power and electricity and that he was now part of a speed force.

Barry ran through a truck, getting the kinetic bomb off and returned to City Hall to give everyone an antidote. Barry then went to rescue his father before knives could drop on him. Barry then confirmed his fathers prediction that he is indeed the Flash. At S.T.A.R. Labs, Henry thanked Wells for taking care of Barry, though Barry didn't seem to happy. The two share a hug before Henry was brought back to Iron Heights. At the precinct, Barry revealed his identity to Eddie and told Eddie to get Iris to stop looking in on Mason Bridge. Barry then described Wells' speech and deduced that he is indeed the Reverse-Flash.

Barry, Eddie, and Joe quickly took down a group of robbers and apprehended them. The following day, they went to Hudson University where Lindsay Kang was stung to death. Barry brought a sample back to S.T.A.R. Labs and they were soon joined by Felicity and Ray Palmer, though Barry told Felicity it wasn't the best time for a visit. At Jitters, Barry and Felicity were interrupted by Eddie and the three ended up making dinner plans between Eddie, Felicity, Barry, Ray, and Iris. Soon after, Bill Carlisle was attacked at Folston Tech but Barry was too late by the time he got there.

He was then attacked by Brie Larvan's bee's and went unconscious. With a defibrillator Cisco built in, the team regained Barry's consciousness. Later that night at the dinner, Barry informed Felicity who Wells really is after Ray discussed how Wells was his personal hero. After things at dinner went downhill with Eddie and Iris, Barry was called back to S.T.A.R. Labs where they learned the bee's were all robotic. At Jitters, Felicity told Barry to inform Caitlin and Cisco about Wells, though Barry told Felicity it could backfire.

Barry later told Iris to trust Eddie and that Eddie only wants to keep her in the light. The team later learned Brie went to her next target, Tina McGee and Barry went to Brie's hideout while Ray went to save Tina. Brie sent bee's to attack Barry but Felicity hacked into the software and shut the bee's down and restrained Brie. Barry rushed over to Cisco after he was stung by a bee and vibrated his hand to use as a defibrillator.

After Tina thanked Barry for the help, Barry asked what happened between her and Wells and learned one day Wells became a completely different person. Barry later called Caitlin and Cisco over and told them about why he and Joe had learned about Wells. When Caitlin was hesitant to believe them, Cisco told them he has had dreams of Wells murdering him.

Barry ran over to Coast City and returned to Central City with pizza. At Joe's house, they inform the rest of the team that Joe and Cisco are headed to Starling City to investigate Wells. Later, Eddie called Barry when there was a report of a male who was trying to sell jewelry which was stolen the night before. Barry rushed over but learned the man was a shape-shifting meta-human. When the team feared the meta-human could copy Barry's powers, they told him to keep hid hands off him.

When Caitlin went to Wells' mansion, Barry rushed over and took her away and told her not to tell Wells anything. Eddie and Barry went to contact Mrs. Bates though soon realize it was actually Hannibal Bates. After Hannibal framed Eddie, Barry ran Eddie out of the precinct and told him S.T.A.R. Labs could keep him off the grid until they cleared his name but Eddie told him to do it the right way and Barry returned him to the precinct. Barry later got a visit from Eddie and was told Captain Singh called in a favor.

As Barry turned his back, Eddie, who actually was Hannibal, hit Barry and hid him. Barry was later found by Caitlin and they return to S.T.A.R. Labs. Caitlin presented Barry with a serum which could disable his shape-shifting abilities. They then got a ping from Barry's phone at the airport and Barry ran over. Barry quickly spotted Hannibal and the two quickly fought before Hannibal was shot with the serum. Barry later gave DA Cecil a full list of everyone Hannibal had impersonated. Later, Joe and Cisco presented Barry and Caitlin with the real Harrison Wells. While Cisco was looking through the schematics of S.T.A.R. Labs, they spotted a hidden room. As they entered the room, they saw the Reverse-Flash suit as well as an article from 2024 reporting the disappearance of the Flash.

They realized that "Wells" was from the future. Barry, Caitlin, and Cisco were then greeted by Gideon who told Barry of his future. Barry, hoping to get some information out of it asked why Wells came to this timeline. Gideon revealed the grim, cold-hard truth: he came here to kill Barry. When they learn Wells was on his way, Barry quickly asked why he killed Nora Allen that night, where Gideon revealed that he did so out of anger after Barry escaped from him. When Wells was heading to the Time Vault, they quickly left. The team then help Cisco see his "dream" properly by constructing glasses that allowed lucid dreaming.

At the precinct, Eddie asked Barry to ask Joe why he did not give his blessing for his proposal to Iris. Later, while Cisco was in his lucid dream, the team learned Wells' true identity, Eobard Thawne, who called them shortly after Cisco woke up. Eobard told him of a fire that just broke out and Barry rushed over. When Barry was unsure what to do, Eobard guided him to use his arms like a vacuum by rotating them fast enough. Later, Eobard told Barry that the only thing stopping him from achieving his goals, 9s himself. Barry later told Joe that they need to recreate the events that happened in Cisco's dream.

At S.T.A.R. Labs, Cisco had rigged the force field so instead of keeping a speedster in, it kept them out, which Barry had tested. Later, when Eobard returned from his lecture, Eobard managed to enter the force-field. As he prepared to kill Cisco, Joe fired three bullets at him, though Barry stopped most of them. The final one Barry was unable to reach and Eobard was shot and killed. Barry was upset that Eobard would never be able to confess however, it turned out to be Hannibal Bates. They were then reminded by Eobard that he was always one step ahead.

Barry told Eobard he could kill him if he'd just let his father out but Eobard told Barry he needed Barry alive. Cisco got a ping from Eobard's time vault and Barry ran over. Barry learned Eobard had camera's everywhere and had access to CCTV footage. Barry warned the team before running over to save Eddie and Iris. Eobard captured Eddie as Barry arrived. Barry told Iris everything was going to be ok and swore that he would bring Eddie home. As he ran off, Barry sent a static shock, much like he had when he was in a coma as Iris realized who the Flash really is.

Barry looked everywhere for Eddie but to no success. When Captain Singh asked where Eddie was, Barry and Joe told Eddie was taking personal time off. When the gold reserve was being attacked by Grodd, who had controlled Eiling, Barry ran over but was quickly stopped as Grodd "whammied" both Eiling and Barry. Back at S.T.A.R. Labs, the team was greeted by Iris, much to the teams shock. Barry explained to Iris that there had been many times he wanted to tell Iris his secret but learned that Joe was right.

Barry and the CCPD later set a trap and capture Eiling. They locked him in the meta-human prison and learn he was controlled by Grodd. With the help of Iris, they learn of sewer workers going missing and Barry, Joe, and Cisco headed down to look for Grodd. Barry was whammied and knocked unconscious and Joe was kidnapped by Grodd. Later, Barry had Cisco build a tech so Grodd couldn't get into his head again. When Iris told Barry that he had been lying to her on the things that mattered most, Barry told Iris she had been lying about her feelings for him also. Barry cut himself off when he realized he couldn't have told Iris about the other timeline. Barry went 5.3 miles away from Grodd and ran toward him in an attempt for a super-sonic punch, though he had failed as Grodd cut his distance down.

Grodd threw Barry on a train track and as Barry's tech broke, Grodd had gotten into Barry's mind once again. As a train went toward Barry, Iris told Barry that he could defeat Grodd and save Joe. Inspired by Iris' words, Barry got out of the tracks on time and as the train passed, challenged Grodd. As Grodd jumped toward him, Barry got out of the way and another train passed and hit Grodd. Barry saved Joe and freed Eiling from the meta-human prison. Barry later told Iris that it's the thought of her that always kept him going. Iris then told Barry that she did have feelings for Barry but Eddie is her boyfriend and missing. Barry then told Iris that he would do the best he could to bring him back.

After continuously searching, Barry told Iris he has yet to still find Eddie but promised he was trying his best. Barry was then called by Cisco who had learned Eobard had been using his wheelchair to absorb Barry's speed. When they learned the particle accelerator was turned on, they realize the reason they couldn't find Eddie and Eobard was because Eobard was holding Eddie hostage at S.T.A.R. Labs. When they opened the particle accelerator, Eobard escaped and Barry chased after him, though Eobard had gotten away.

Later Barry apologized to Eddie for not finding him sooner. Barry said they needed to get the meta-humans out as though they are dangerous, they don't deserve to die. Barry suggested they transfer them to the super-max on Lian Yu. Desperate, Barry looked to Leonard Snart to help transfer the meta-humans, under one condition, Barry erase all criminal records of him, though Joe was very disappointed Barry looked to such lengths.

They had the meta-humans placed in a truck owned by Cisco's family and used the device from Eobard's wheelchair to disable the meta-humans powers temporarily. Once they reached the hangar, the meta-humans had escaped and began attacking Barry, Cisco, Caitlin, and Joe. They then learned it was Leonard who had sabotaged the truck and let the meta-humans escape. Leonard told Barry he had done so as they all now owe him and could be useful as a part of his Rogues Gallery. When Barry asked why he had spared him, Leonard told him he now owes him as well.

At S.T.A.R. Labs, Barry felt guilt having his plan failed and wondered how Oliver could do whatever it took to get what he needed. The particle accelerator then was fully charged and online. Eobard approached S.T.A.R. Labs and Barry ran out to face him. Eobard told Barry he couldn't stop him if he had tried as Eobard was always faster. Barry was then joined by Firestorm and Oliver. Barry and Eobard faced off as Oliver tried to get a clear shot at Eobard. Barry was thrown towards a S.T.A.R. Labs sign and as Eobard used his hands as a vacuum to blow Firestorm away, Barry ran over to grab Firestorm.

Barry ran back and stopped Eobard before he could kill Oliver. Barry and Eobard fought on the roof of S.T.A.R. Labs and Eobard was thrown off S.T.A.R. Labs by Firestorm.Eobard was then shot by Oliver with another nanite arrow, disabling Eobards speed and making him unconscious. Barry thanked Oliver and Firestorm for their help and looked over Eobard, finally taking down the man who murdered his mother. Barry ran off to Nanda Parbat and freed Oliver's friends. When Felicity asked to help save Starling City, Barry said he had a long overdue conversation with Eobard.

Barry asked why Eobard he murdered his mother, Eobard told him he hates him for something future Barry had done. He reveals that killing Nora was not his original intention, as he really went back 15 years to kill Barry when he was still a child. When Barry got his past self to safety, Thawne was so angry that he took it out on Nora by killing her. Eobard then told both of them could get what they want, Barry return to save his mother which would allow Eobard to return to his time. Barry presented this information to the team who all agreed he should do so. Barry asked Joe why he was so supportive and Joe told him though he had been a great son, he wants Barry growing up with his mother and his real father.

Barry told his father he could save his mother but Henry told him it was to dangerous due to the repercussions of time travel. Iris told Barry she knew of a possible future of them being married in the future and joked she was never a fan of hyphenated names. Eobard explained how Barry was going to go back to the night his mother was murdered, he warned Barry that he could die if he didn't reach the right velocity. Later, Barry was informed that as well as dying, Barry could cause a singularity which could destroy earth and continue even after the earth is gone. Barry along with the rest of the team attended Ronnie and Caitlin's wedding before Barry prepared to save his mother.

Barry said his goodbye's to his friends and foster family. Barry was then told he had 1:52 seconds otherwise a singularity would form. Eobard told Barry he holds both of their futures and then told him to run. As Barry ran, he saw the past, present, and future before traveling back to the night his mother was murdered. When Barry arrived to the night, Barry looked on as his future self battled Eobard. His future self then signaled him to stay back and Barry looked away as his future self rescued his younger self and Eobard murdered his mother. When Eobard had left, he went and told his mother that he and his father turned out to be ok. His mother looked at him, proud of her son, and Barry tells her goodbye, before she dies in front of him, her last words being "Goodbye, Barry."

Barry returned and broke Eobard's time machine. Eobard asked why he didn't save his mother and have everything he had wanted and Barry told Eobard he already has. Barry and Eobard battled though Eobard quickly has the upper hand. When Eobard told he was going to kill as his friends and family, Eddie shot himself and Eobard fell back. Cisco quickly realized that Eobard was being erased from existence and before Eobard vanished, Eobard told Barry he controlled his life all his life and wondered how he would go on without him.

A singularity formed in the particle accelerator and the team rushed out. As they watched the singularity eat Central City, Barry told the team he had to try and stop it, even with little chance of success. Barry ran through Central City and jumped towards the singularity.[36] As he stabilized the singularity, Firestorm flew toward the singularity and Barry watched as the two separate, causing the singularity to close. As Martin Stein plummeted to the ground, Barry caught him. When Caitlin arrived at their location and learned Ronnie didn't make it, Barry hugged Caitlin and looked toward the sky. For the next six months, Barry lived in solitude, blaming the deaths of Eddie and Ronnie on himself.

Barry Allen
Barry is described as someone who complements Felicity Smoak's intellect level, both when it comes to forensics, as she claims it's not her strong suit, and science in general. He is also someone who is regularly late as he missed a train and cab all to get to Queen Consolidated's warehouse, and missed the last train back to Central City. He is also considered a comic geek.

Much like Oliver Queen, Barry has a strong sense of justice, due to the fact he knows his father is innocent of a crime he was convicted of. He joins the forensics department to both learn how to investigate crimes, and study cases with unexplained elements, to prove his personal account of his mother's murder true, and ultimately, free his father. Barry is very intelligent, like Felicity, he is socially awkward, as he sometimes gets nervous and babbles.

Barry has good morals, as he does not like to lie about who he really is, like when he first met, Oliver, Felicity and Quentin Lance, and told them he was a forensic scientist, this was only because he knew they wouldn't take him very seriously if they knew he was only an assistant forensic scientist (at the time) when Oliver confronted him, after he found out who Barry really is, he did not try to deny it, but explained the reason why he did it.

Barry has a lot of respect for the vigilante known as the Arrow. When he found out that Oliver/the Arrow are the same person he is amazed, he also saved his life after he was injured by Cyrus Gold and consequently poisoned, despite the fact that he barely knew Oliver at the time, he also keeps his secret. Despite his respect for Oliver, Barry is not above standing up to him, like when he pointed out that Oliver was being a jerk to Felicity, though he said this in a respectable way.

Additionally, as said several times by Joe West and seen many times throughout time, once Barry makes up his mind about something, makes a decision or sets his mind to something, it is impossible for anyone to talk him out of it, including Joe, Iris West and even Henry Allen.

When he first discovered his new-found powers, Barry wanted to help people, like when he first tried to stop Clyde Mardon, someone unintentionally got killed because of his actions, and he lost his confidence, however, after getting advice from Oliver Queen, he regained his confidence, as his skills as a superhero improves, Barry becomes more and more confident.

Barry's sense of Justice has gotten stronger to the point of using his new-found powers not only to help people, but to also fight other meta-humans who would use their powers for evil intentions. Including the meta-human who murdered his mother.

Barry is very stubborn and apparently isn't likely to learn from his flaws until experiencing them first hand, as seen during his training with Oliver. This prompted Oliver to show Barry a potential consequence of not surveying his surroundings before charging at an enemy by shooting him with two remote controlled crossbows.

However, this is proven to be untrue; as Barry is more than capable of learning from his mistakes, even if he does not experience them first hand; despite his stubbornness.

Despite his pride, unlike Oliver; Barry is not above apologizing or admitting when he is wrong, even if he doesn't like to do it in the first place.

Despite his dislike of crime and meta-humans who use their powers for evil intentions, killing and torturing his enemies is a line that Barry would never cross, as he criticized Oliver for torturing Klaus Markos to gain the location of Digger Harkness. He even stated that he does not use his bad experiences as an excuse to torture people in general who makes him angry.

Barry is selfless and honorable; for example, when he found out that his good friend Eddie Thawne was going to ask Iris to marry him, Barry did not try to stop this engagement, despite recently discovering future events; that Iris will become his wife, instead of Eddie's. Also, he pushed Patty Spivot away partly because he didn't want her to sacrifice her dream of being in CSI for him.

However, after Eddie sacrificed himself so that his descendant Eobard would have never been born and Ronnie Raymond had done the same so Central City could be saved, Barry's personality became slightly darker; he became more reclusive, distant and cold to his friends, he broke up Team Flash and went the "Lone Wolf". He also began to doubt himself as a superhero as he couldn't have saved Eddie and Ronnie and even considered not going to Central City's Flash Day, but after being motivated by Iris, he decided to go and reunite Team Flash. Even with this, he still remains somewhat guarded, especially after being brutally beaten by Zoom, he became even more so, even in his love life, as shown with Patty to point that he let her go for her own safety and happiness.

Barry became less trustful of people, when Hunter Zolomon (posing as "Jay Garrick") claimed that Earth One was in danger by another speedster called Zoom, Barry did not believe it, even though most of his friends did, but this was mostly due to the fact that Jay reminded him of Eobard Thawne, he eventually overcame his suspicions and allowed Jay to train him to defeat Sand Demon, however, Barry's suspicions of "Jay" ultimately turned out to be correct, as he was later revealed to be the supervillain Zoom.

Barry began to show less concern for his enemies' well-being as he lured Atom Smasher into a chamber that gave him an overload of nuclear energy, which killed him, and solidified Sand Demon which again kills him, however, Barry probably didn't expect it would kill them. His killing of Atom Smasher was due to his strong belief he would harm others. However, he did apologize to Atom Smasher before he died as he felt guilt, care and remorse, while he felt none for Sand Demon's death; this is likely because the latter villain was a homicidal maniac who did nothing to try to avoid the death of innocents. Finally, he was willing to kill a reanimated and mindless Tony Woodward, but felt it as a mercy killing and said that despite them being enemies, he still wanted Tony to be at rest, while Tony was also already dead to begin with and his corpse was simply reanimated, meaning that he was not actually killing him.

However, when faced with the notion of having to kill Solovar in an effort to prevent them from invading Earth One, Caitlin asked him if he was willing to take a life, meaning that he may have not truly viewed himself as having killed his enemies since he did not kill them directly. He was even tempted to try and kill Grodd due to the threat he constantly posed towards Central City and his allies, while Iris and Harry convinced him to not risk losing his humanity to achieve victory. While fighting Savitar, he threatened to kill him after Wally West was trapped in the Speed Force and even attempted to kill him with a chokehold when he revealed himself as a future version of Barry. He was even tempted to kill himself to stop Savitar's creation, but relented when he was reminded of Eobard Thawne still being in existence despite the suicide of his past relative, Eddie Thawne. When stealing salvaged technology from the Dominators, he was prepared to kill King Shark, who was guarding it, using Leonard Snart's Cold Gun, until he was told that there was another way.

Barry is a forgiving individual, as after Eobard was erased from existence, it took him months before he finally forgave the latter for murdering his mother, and framing his father for his crime. He stated that no matter how much he hated Eobard, he couldn't bare hating him anymore. However, this hatred was apparently rekindled when Eobard's time remnant appeared, enough that Barry came close to beating him to death. Barry showed great outrage and disgust at learning that their antagonistic relationship in the future and Eobard's own hatred of Barry was because Eobard was jealous of the Flash and wanted to become better than him. After being forced to release Eobard from captivity, they both stated that they hated each other, with Barry being bitter at having Eobard murder his mother in the past to restore the timeline.

Despite his honorable ways and proclivity for pacifism in the face of deadly and often ruthless and sociopathic enemies, Barry does harbor some very disturbing and homicidal feelings towards some of his enemies in particular. These two being Zoom and the Reverse-Flash, due to their parts in the deaths of his father and mother respectively. After the capture of Eobard Thawne in the particle accelerator on the first occasion, Barry expressed an unhinged and blood-thirsty desire to kill him, even spitting with rage when he voiced this overwhelming need of his. This is in almost direct opposition to his normally restrained and merciful attitude towards his enemies.

His desire to kill Hunter Zolomon may even be greater, due to how thoroughly Hunter had deceived Barry and his friends, and how Hunter tortured Barry by kidnapping his father and then stabbing him through the chest with a vibrating hand. All the while this death took place in the same room where, approximately 16 years prior, Barry's mother was murdered by Eobard. This replication of his mother's murder with his father profoundly affected Barry, and awakened a need for cold-blooded vengeance in him that he has never felt before, having had the pain of losing both parents in the same way, each to a deranged speedster, compound one another, tearing him apart emotionally.

Because of all the tragedy Barry had suffered and being unable to cope with it, he made a trip back in time, saving his mother, reforming the current timeline. Despite him seemingly recovering, Barry seemed to be trying to kill the Rival after he impaled Wally West in the back. The only thing stopping him from doing so was his memories fading away.

Once Barry realized how big a mistake he made once seeing Wally injured, he attempted to correct the time, yet was only somewhat successful. When Jay Garrick intervened in his attempts to correct the damaged timeline, he taught Barry that time travel must not be abused, and he must learn to live with his mistakes, instead always trying to undo them.

Although Barry does have guilt and remorse for his actions, especially if they have unintentionally hurt the people he cares about, at the same time, arguably Barry's greatest fault is his guilt for actions he believes that could have been stopped. Due to this, he has tried rectifying his mistakes by time travel, but has actually ended up causing even bigger problems than what he initially sought out to prevent. The most major example being the creation of Flashpoint, which drew in not only Savitar, but the Dominators as well.

Barry's heroic and peaceful nature hid a more complex and powerful set of emotions that he does not fully express but has always harbored on a subconscious level. While as both a civilian and the Flash or when pushed over the edge by enemies, Barry has been known to act on nearly 14 years of repressed anger and emotional stress. These emotions were obvious after being exposed to Roy Bivolo, voicing unfounded contempt for others unusual in Barry's usually calm nature and respectful attitude such as snapping at Joe for imprisoning and criminalising his father, speaking down at David Singh for his constant barking/disrespect and condescendingly voicing jealousy for the Arrow. Barry admits that after being cured that although it was Bivolo's doing, he did mean some of the things he said during his fight with Oliver.

After having sacrificed himself to and then six months later is released from the Speed Force, Barry's personality has changed drastically, though retaining some of his traits prior to being imprisoned in the Speed Force, he seems to be free from his tragic past as he moved on from his mistakes and parents' deaths and seemingly more happier than ever. While initially suffering from dementia or schizophasia, he seemed to recover from this state after hearing Iris was kidnapped by a Samuroid and later came to her rescue.

Due to his bad experiences with Eobard Thawne and Hunter Zolomon respectively, Barry is not fooled at all by an individual's ability to appear kind-natured, he suspected that Clifford DeVoe was a meta-human (after the Council of Wells informed him that the latter was the mastermind behind the bus meta-humans) despite the fact that he did not have a criminal record, his suspicions of Clifford increased when he and his wife Marlize lied to his superior officer David Singh, claiming that he was harassing Clifford (when in truth, he was only conducting the necessary investigation) even when every member of Team Flash believed that he was innocent - Barry's suspicions were proven to be correct yet again; regarding Clifford.

After Barry was framed by Clifford and Marlize for murder, he refused to reveal his identity as the Flash to the entire court (even though it could have exonerated him) this was because Barry knows full well, that it his superhero identity is revealed to the public, every single one of his enemies would not only come after him, but also after the people he cares about.

Barry has displayed a greater sense of responsibility when it comes to his powers, immediately shooting down Jessie's idea to use time travel to stop a nuclear bomb, remembering from experience how dangerous and damaging it can be for everyone. Also he is more willing to be reasonable to turning down certain decisions, like accepting that Harry's idea to throw the nuclear bomb into the Speed Force was too risky to it, every speedsters throughout existence and existence itself.

Flash of 2024
""In the future?"  "In a future, yes. We're enemies, rivals, opposites, reverses of one another.""

- —Barry Allen and Eobard Thawne In Barry's true original timeline before it was changed by Eobard Thawne, the Flash's history was very different. Having a simple childhood of growing up with his parents, Barry did not have to face the emotional stresses from the current timeline. Despite this, his sense of duty remained the same. He also still ended up with his childhood crush/best friend Iris, even getting married. His career in law enforcement eventually got him promoted to director of the CSI division.

His biggest change in becoming a superhero was that Barry gained his powers in the year 2020, when Tess Morgan and Harrison Wells successfully activated the S.T.A.R. Labs particle accelerator for the first time. The Flash became a veteran hero and a founding memory of a unknown but revered group. He was also respected by his nemesis, rivaling the Reverse-Flash at his prime in both speed and cunning. Despite their contrasting natures and Eobard's outspoken distain of him, the future speedster admits to wondering just which one of them was truly right.

It's unknown whether Barry will become this Flash in the current timeline, as Eobard noted it to be but "a" version of the future, but regardless, a future Flash, presumably a time remnant created to maintain the flow of events, traveled to the year 2000 to stop Reverse-Flash from killing Barry's childhood counterpart. During the battle, the veteran Flash saw his 2015-counterpart. Realizing that 2015-Flash was there to change time, 2024-Flash warned the younger speedster to stay out if, showing a deep respect and concern for maintaining the natural timeline. While he was unable to save Nora Allen, the Flash spirited his kid-self away from Reverse-Flash, before mysteriously disappearing in a flash of lightning, possibly sacrificing himself to the fate of an aberration.

In the future in which Iris dies, 2024-Barry's struggles left him in utter despair and isolation from others, due to the love of his life, Iris West, being killed by Savitar 4 years prior, which caused him to neglect everyone important in his life. Having already avenged Iris by imprisoning Savitar, the future Barry had no motivation left to continue his super heroics, resigning from it completely and spent most of his time in S.T.A.R. Labs, particularly in the time vault, looking at photos of Iris and him. After meeting his younger-self, he was reinvigorated with hope, becoming the Flash again and bringing his team back together. This future was later erased when Savitar killed H.R. instead of Iris.

Powers and Abilities

 * Speed Force Connection/Meta-Human Physiology: Barry's powers come from a connection to the Speed Force, gained when struck by dark matter lightning and exposed to various chemicals. This altered and supercharged his DNA, cells, and neurotransmitters, augmenting his physiology. With his bones, joints, and tissue all enhanced, he obtained a lean-muscular frame well-beyond peak human condition to easily handle the rigors of his powers. This includes resisting high-level friction, inertia, air pressure, reduced oxygen, vectors and kinetic impact. After regaining his powers from inside the Speed Force, his connection to and understanding of it increased considerably. With a new-found instinctual control and efficiency, Barry can perform more advanced abilities and improved his natural performance for much longer unhindered. After six months in the Speed Force, all Barry's capacities developed to exceedingly potent levels, reaching the highest known performance.
 * Accelerated Healing Factor: Barry's molecules move at accelerated rates, mending damage far quicker and more efficiently than normal humans. Without treatment, most damage heals in hours if not minutes with no lingering signs. Even normally permanent damage, like paraplegia, is completely repaired in days. His body can break down food more efficiently than a regular human and, as a result, expels very little waste products that he can exhale through his skin. He recovers from in seconds if not is immune to any illness or contaminant. He even has a greater resilience to radiation, only suffering minor burns. 2,000 milligrams of horse tranquilizer only momentarily slowed him down until his body burned through it. This also enhances his vitality, drastically reducing his aging process while extending his health and longevity; in a potential 2024, Barry looked exactly the same as when first became the Flash.
 * Bodily Vibration: Barry can vibrate his body for various effects. This can mask his form from being clearly perceived or distort his vocal cords to disguise his voice. His vibrations can forcibly expel any toxins in him. He can also generate enough heat to recover and stay thermally insulated from extreme cold. Offensively, he can vibrate his limbs to seamlessly grind through highly solid targets, which he can use to harm or kill a person, as he was tempted to do to Zoom and the Reverse-Flash. Alternatively, he can use this as a weapon by passing his punch through a person's body, incapacitating them as he did against Solovar. During his final fight against Savitar, Barry's efficiency could simultaneously shift the time remnant out of his armor and encase himself in it. He can also pass through one target while simultaneously making harmless contact with another.
 * Intangibility: By vibrating his molecules at the frequency of air, Barry can physically pass through solid matter, even highly complex matter like carbine while in a universe of a different vibrational nature. He do this with multiple targets, saving an entire moving train and hundreds of passengers. He can also harmlessly pass through living individuals as he did to escape Atom Smasher's grasp.
 * Invisibility: Barry can vibrate his body so fast that that he can no longer be perceived by the human eye. When Clifford DeVoe trapped Barry in a force-field prison that prevented the latter from phasing through it, Barry did this in order to "trick" Clifford DeVoe into releasing him.
 * Seismokinesis: By vibrating at varying frequencies and with different levels of force, Barry can create small tremors to induce extreme amounts of jolt on any target he touches, even disrupt the inter-molecular bonds and cause it to shatter. This can lead to many effects such as molecular combustion upon physical contact with the target. His vibrations can even shatter targets into fragments, as he did to Savitar's armor once inside it.
 * Electrokinesis: Barry can produce yellow electricity, his Speed Force energy, from his body. It is commonly seen when running. While mostly used to boost his speed to higher levels, it can be used in other ways. The intensity of it can interfere with the surrounding electronics and overwhelm electric-absorption, as seen from Blackout. He can focus the energy into specific body parts to produce a strong static shock on contact with the target. Taught by Hunter Zolomon, Barry can harness this electricity to repeatedly hurl lightning bolts to stun or repel enemies, and also electrify a surface. Barry can also absorb electricity from other sources, giving simultaneously giving him an extra boost when running or throwing lightning.
 * Speed Force Sharing: Barry can expand his Speed Force aura to protect others he carries while moving at super speed. Taught by Jay Garrick, Barry can also siphon the speed from another speedster by absorbing some of their energy to bolster his own speed. After escaping from the Speed Force, Barry gained a much greater a understanding of his power, able to use it in more passive means. By touching others, he can temporarily share his energy, letting them move, think, and heal as fast as himself, as this let Jesse recover immediately from a coma. By channeling enough energy, others can independently move as speedsters without exhausting or affecting their own powers, until they burn through the borrowed energy. Barry is currently the only speedster known able to do so.
 * Enhanced Strength: Barry's physical strength has been heightened beyond peak human capacities, greatly belying his slim built, allowing him to be able to carry multiple people at once while speeding away with them. When charging his momentum, he could smash through machinery with his bare hands or send opponents flying through the air without first running. He can even stop a moving car unaided.
 * Superhuman Agility: Barry has demonstrated flawless coordination, equilibrium and dexterity. He can change direction with immediate sharp turns without sliding or losing balance and instantly stop running on the spot. He can jump and run along falling debris and launch himself tremendous distances without build-up.
 * Superhuman Durability:  Barry possesses inhuman resilience, most commonly seen from being unaffected by momentum build-up. He can take attacks and exertion, even survive impacts that would easily kill normal humans. While not invulnerable nor immune to pain, he withstood powerful lightning bolts, concussive shockwaves, sonic blasts and inhumanly strong strikes, only being momentarily stunned. After regaining his powers, his resilience increased, quickly rebounding from zombie-Girder's blows, who previously seriously injured him in a single blow. During the Earth-X invasion, Barry blocked bullets with his arm and took no damage.
 * Superhuman Mental Process:  Barry's powers also make his system and thought processing able to take in and retain information just as fast and efficiently. Even while using his raw speed, he can clearly think, react to events, and perform actions long before normal humans can perceive them. This lets him learn in a small fraction of the normal time, able to read and familiarize himself with Earth Two science within seconds. After six months in the Speed Force, Barry's brain activity became over 5 times faster than before.
 * Superhuman Perceptions:  Barry's senses are also enhanced. This allows Barry to perceive the world as if it is nearly frozen. He can see and hear normally, even while moving at speeds faster than sound, where this would normally be impossible. Barry became able to easily perceive the attacks of other powerful speedsters. This heightened alertness enables him to instantly read and adapt to the situation. His perception of time, however, seems to vary by his emotional state, as in one instance, when he was waiting to check out from work, he described it as feeling as if it were hours away, while in real time it was merely minutes.
 * Superhuman Reflexes: Barry's reaction time is augmented to superhuman levels, allowing him to react to danger and events far faster than normal humans. When shot in the neck on his blindside, Barry caught the bullet and minimized the damage before it could fully penetrate his skin. He also became able to easily react to the attacks of other speedsters.
 * Superhuman Speed:  Barry can move at such vast speeds; Eobard Thawne claims Barry's speed is potentially limitless. He can run across vertical structures and ceilings, over stretching seas, effortlessly catch speeding projectiles, complete his various daily activities in seconds, and even casual walking can go unnoticed by normal people. While reaching Mach 3.3 on his own and later Mach 13.2 from tachyons, since increasing connection to the Speed Force, Barry has continually grown faster. Even when weakened in the Flashpoint timeline, he was able to decisively beat the Rival. After six months trapped in the Speed Force, his speed reached levels far exceeding all other known super-fast beings, even going too fast for fellow speedster Wally to follow and only Reverse-Flash able to keep up.
 * Superhuman Momentum:  Barry can generate great amounts of physical force through kinetic energy, simulating superhuman strength, even in a stationary position. Even little exertions from this build-up can generate tremendous, able to knock a person out. He can propel himself to jump tremendous heights and distances. He can also create substantial frictional force with any object he touches, and exert enough force to hurl people into the air. This seemingly negates the weight of his target, able to move about as if targets are frozen, even in mid-air. This also lets him propel and manipulate the targets' flight path, including launched bullet with no loss of force and hurl them through a powerful barrier, followed by a person. He can completely remove the physical force from massive tidal waves, stabilize a giant singularity, or dispel F3 tornadoes by running around them. He can also snap his fingers to ignite flammable gas with the friction. After escaping the Speed Force, Barry can generate enough force to break down the natural durability of a target, as he effortlessly shattered his way out of his meta-human cell.
 * Aerokinesis:  Barry can use his speed to generate air flows on various levels and for various effects. He can create vortexes to suffocate people or extinguish fires by forming it around them. He can create large and strong tornadoes, able to repel massive targets. Alternatively, he can use this skill to propel himself through the air as a pseudo-form of flying. Later, Iris taught Barry, from her own experience as a speedster, to use this build-up to gather and direct enough water into a tidal wave capable to disperse a giant fire cyclone of over 6000 degrees Fahrenheit. With enough momentum, he can generate a powerful sonic boom through his punch able to destroy a crashing satellite.
 * Interdimensional Travel:  Barry can move fast enough to break open portals between dimensions, allowing him to travel to different universes. If desired, Barry can also bring others with him as he did with Harry and Cisco to Earth Two. While originally he could not consciously control this, as his first solo use was done by accident and required assistance to return home, after greatly increasing his Speed Force connection, he can break open portals of his own accord and consciously chose his destination, even into the Speed Force itself.
 * Speed Mirages:  Barry can generate illusions of himself to make it appear as if he in many places at once, when in reality he is simply bouncing back and forth too fast for the human mind to perceive the difference. He can create dozens of after-images, allowing him to disorientate his enemies and then catch them off guard.
 * Time Travel:  Barry's speed can breach the temporal barriers, letting him enter different points in time. While originally only accessed by accident when under extreme stress, Barry learned to use it at will and arrive at a destination with pinpoint accuracy. He can do this in one of two ways; either enter timelines independent from himself and unaffected by his travels or perform a time do-over, wherein he "merges" with his temporal counterpart to be fully immerse in the timeline. Regardless of the changes he makes, Barry's powers allow him to retain all memories of the previous timeline in addition to the new timeline and differentiate between them. Even if Barry is not responsible for the time alterations, he can still remain somewhat unaffected by it; as he remembers that John Diggle and Lyla Michaels had a daughter instead of a son in the original timeline.
 * Time Remnant Constructs:  Barry is able to "create" a time remnant by traveling back to moments before his current-self time travels, hailing from a future that no longer exists. This allows Barry to be two places at once, enabling him to interact with the world for two separate actions simultaneously. If desired, Barry can create dozens of time remnants at once.
 * Temporal Dilution:  By generating enough energy, Barry can move so fast that time essentially slows down time relative to him, to a complete standstill (dubbed "Flashtime"). However, he must continuously concentrate on this action as losing such focus will gradually speed back up again before ultimately returning to its original flow. He can pull others into this state, however, non-speedsters will quickly tire from it as their bodies aren't accustomed to moving at such great speeds. Other speedsters can also remain unaffected by this even provided they retain enough stamina to expand their Speed Force energy.
 * Superhuman Stamina:  Barry can handle the stresses of extreme racing without noticeable distress, letting him function much longer than normal humans unhindered. His enhanced stamina is due to his augmented physiology, which builds up little to no lactic acid or fatigue toxins. Even after running from coast to coast of the country to pick up a pizza, Barry remained unfazed from the prolonged running. However, while his stamina is greater than most speedsters, Barry's reserves are not inexhaustible. Extreme and extended uses of his more advanced powers will eventually drain him.

Trivia

 * Barry is the first character to discover that Oliver Queen is The Arrow.
 * According to his Facebook profile, his favorite song is Lady Gaga's "Poker Face".
