Life on Krypton
One night Kara stayed up late to see her mother. Questioning her mother as to why she had come home so late, Kara was told by Alura that a Hellgrammite had been brought before the citadel. When Kara mentioned that she wanted to help people like Alura did one day, she was told by her mother that she would, as she had the heart of a hero. After being told to get some rest by her mother, Kara researched Hellgrammites.
Kara was given a spy beacon by her aunt, Astra, which could be used to call her. When Astra disappeared, Kara messaged her and Astra arrived, telling her that Krypton is dying. Unbeknownst to Kara, it was part of Alura's plan to lure Astra out of hiding to arrest her for her crimes.
When she was thirteen years old, Kara was sent to Earth from the dying planet of Krypton, charged with protecting her baby cousin Kal-El. Her mother told her that due to Earth's yellow sun, she'd have extraordinary powers and go on to do amazing things. However, when Krypton exploded, Kara's ship was knocked off course by the shock wave, pushing it into the Phantom Zone. She slept there for 24 years until she awoke and noticed computer console in her dashboard that lights up with a logo with three dots in a triangular shape, before Fort Rozz's engines activated.
Sent to Earth
Kara's pod finally landed on Earth. Since time doesn't pass in the Phantom Zone, she still appeared as a 13-year-old girl. She was found by a then adult Kal-El, who had gone on to fame as Superman. She was then taken by Kal-El to live with Jeremiah and Eliza Danvers, a pair of scientists who once helped him understand his own abilities.
She was enrolled at Midvale Junior High School along with Alex. Kara was freaked out by her new world along with her developing powers. When they went to the beach she embarrassed Alex by staring at the birds as they did not have them on Krypton. When a car crashed close by Kara ran at super-speed to the rescue saving a mother and her child with her super-strength. However Alex was injured by a car door when it exploded. After that, Jeremiah and Kara decided that it was best for Kara to hide her powers, and Jeremiah gave her a pair of glasses she could wear to suppress her vision.On the roof of the Danvers' house Kara convinced Alex to sneak out and go flying with her, despite the latter's initial protests. Kara and Alex were later caught sneaking in by Eliza and Jeremiah, and lectured about the rules. After someone knocked on the door, the girls were sent up to their room, with Eliza telling Kara not to use her super hearing to listen in on their conversation.Kara was invited by Superman to see the Fortress of Solitude several times, though she rejected the offers as she thought it would remind her of Krypton.
Embracing her powers Deciding that the world didn't need another hero, for the next twelve years Kara decided to live a normal life. She later went in for an interview at CatCo, meeting Winn Schott, and using her abilities during the interview to secure the job.
After a failed date, Kara saw on the news that Flight 237, the one her sister Alex Danvers was flying on to go to her conference in Geneva, was going down. Attempting to save the flight, Kara used her abilities for the first time in years, successfully helping the plane land, though not without causing damage to Otto Binder Bridge. Though was later berated at her apartment by Alex, who was upset that she had revealed herself to the world, and couldn't take it back. Deciding to become a hero, Kara confided her secret in Winn the next the day, on the roof of CatCo. With Winn's help, a costume was made, and Kara was able to stop a bank robbery and car chase.
Kara was later subdued by the Department of Extra-Normal Operations while trying to stop a fire, the latter whom used Kryptonite darts. Meeting Director Hank Henshaw at the DEO base, it was explained to her that when her ship got loose from the Phantom Zone it dragged Fort Rozz, Krypton's maximum security prison with it to Earth. Though she offered to help, her offer was rejected by Henshaw. The next day, Kara was furious Cat Grant had dubbed her Supergirl, later being contacted by a Fort Rozz escapee, Vartox, and although she was defeated on their first encounter, she later convinced Henshaw to give her another try, in which she defeated him. It was later revealed to Kara that Superman had asked James to come to National City, as Superman had asked him to come there to keep an eye on her. Kara was confused as to why he didn't just tell her he wanted her to be a hero himself, with James revealing to her that Superman wanted her to choose it for herself, the same way he had to, as that was what made a hero. Kara was then given the blanket Kal-El was wrapped in as a baby, that James had been entrusted to give to Kara for her to use as a cape.
A week later, Kara tested her abilities with the D.E.O.. She later stopped a fire at the National City Port, and the next day at work, Kara was present at the meeting where Cat told her employees that she wanted an interview with Supergirl. However, Kara soon after told James that she wasn't going to do it, as Cat would recognize her. Kara was later contacted by Alex regarding an alien theft at Plastino Chemicals, with Kara identifying it as a Hellgrammite afterwards. Kara offered to subdue the Hellgrammite, though her offer was rejected by Henshaw who wanted her to prove that she could handle herself beforehand. Kara was then brought into the D.E.O. training room and swiftly defeated by Alex. Arriving into work the next day sore, Kara took advice given by Cat Grant of starting small and working her way up, and enlisted the help of both Winn and James. With their help, Kara was able to handle several situations. Later at her apartment, she thanked Winn and James for their help, and was soon after given an apology by Alex. The following day, Kara listened in on James' conversation with Cat, giving him a pep-talk after he was given a dilemma by Cat. Directly after, Kara was called by Henshaw who notified her that Alex had been abducted by the Hellgrammite. After criticizing Henshaw, Kara tracked down Alex at the warehouse she was being held captive at. There, she discovered her Aunt Astra was still alive, and a fight between the two ensued. Kara and Alex were saved from Astra by Henshaw, and later at the D.E.O. Kara was shown a room that had been setup for her to communicate with her own personal A.I.. Kara later carried Cat's car to a remote location for their interview, telling Grant that James Olsen had told her that Cat had wanted to talk to her.
During her interview with Cat, Kara accidentally revealed that her and Superman were cousins, flying off afterwards. The next morning at Noonan's, Kara was teased about her crush on James by Alex, who also told her she had to stop telling people her identity as Supergirl. At CatCo, Cat told Kara that she would be writing an expose on Supergirl for a issue of their monthly magazine, and that'd they be having a big party to launch it. Kara was later alerted by Agent Vasquez of a multiple car collision on the highway. While there she encountered a masked villain who attacked her, after brief battle between the two, the man flew away after she damaged his suit. Back at the D.E.O. headquarters, the man was identified as Reactron, an old villain of Superman's. Afterwards Kara was told by Henshaw that the D.E.O. wasn't going to help her deal with him, as Reactron was human, and fell out of their jurisdiction. Later, Kara and James were shown Ed Flaherty's old office by Winn, who had turned it into a base for their Supergirl matters. While going over Reactron's powers and his history with Superman, James suggested that Kara call Superman for assistance, much to her reluctance. After being informed of Maxwell Lord's capture by Reactron, and discovering the latter's identity, Kara found out the location of Reactron's hideout, saving Maxwell though she was soon defeated by Reactron, and subsequently saved by Superman. The next day she discovered that Supergirl was being discredited by Lord in the media because of Superman's intervention, and dismissed James after discovering that James called him. At Cat's party, Kara danced with Winn and later James, though Reactron broke in interrupting them. As Supergirl, Kara stops him, successfully removeing the power core, powering his suit. Back at her apartment, Kara and Alex make up, with Alex suggesting that Kara asks James out. However when Kara goes to his office the next day, Kara sees Lucy Lane, James' ex, who arrived to talk to him. Kara overhears the conversation, leading her to believe that Lucy wants to get back with James. Upset about this, even giving Winn the cold shoulder, Kara received a texted apology from Clark.
While flying in National City, Kara encountered a drone and destroyed it, afterwards blaming the D.E.O. for following her. Later at CatCo, Kara offered to watch Cat Grant's son after discovering that Grant had won the Siegel Award for Women in Media, and didn't have anyone to watch him. At Noonan's Kara talked with James about his relationship problems with Lucy Lane, leaving after finding out a bomb had went off in a building nearby. After saving the building, Kara was soon after reminded by a call from Cat Grant, that she was late to pick up Carter. After picking up Carter at St. Edmund Hall, Kara brought him back to CatCo, and later stopped James from venting to her about Lucy. Kara then received a call from Alex about the bomb at Lord Technologies, arriving there as Supergirl, and successfully getting the bomb clear of the city, being knocked unconscious from the bomb's explosion. She later awoke at the D.E.O., and was informed of the bomber's identity, Ethan Knox. Though she offered to help, Kara was ordered by Alex to sit out on the case, after falling from the height she had. While getting lunch from Noonan's, Kara encountered Lucy Lane who confided in her about her problems with James, which she later recounted to James. While going to protect Maxwell Lord's super train on it's opening, Kara was alerted to a bomb at Lord Air Terminal. Kara then received a call from Winn who told her both Carter and Knox were on the train, deducing that there two bombs, and telling Alex and Hank to handle the airport, and she'd handle the train. Arriving on the train, Supergirl alerted Lord of the bomb, and told him and Carter to get all of the passengers to the back of the train. After finding Knox, she pleaded with him to deactivate the bomb, though to no avail, having to deattach the train car that Ethan was in from the rest of the train, watching it blow up from a distance. The next morning she was berated by Cat for letting Carter get onto the train, and later that day confronted Maxwell Lord after discovering he was the true culprit behind the bombings.
As Supergirl, Kara stopped an alien convict from escaping the D.E.O.. At her apartment, Kara along with Alex greeted Alex's mother, Eliza Danvers, with the Eliza complimenting Kara on her work as Supergirl. At CatcCo Kara invited Winn to her family's Thanksgiving dinner, after finding out he had no plans. Afterwards she listened in on Cat demoting Leslie Willis to the traffic chopper, and she later in the day had to save Leslie from the helicopter after lightning hit the aircraft. While doing so, lightning deflected off of Kara it deflected onto Leslie, putting her into the hospital. The next day, Kara went with Cat to visit Leslie in National City Hospital. During Thanksgiving dinner, Kara announced that before everyone ate, she wanted them to go around saying what they were all grateful for. After going first, Kara excused herself to answer a call from James. After an argument between Eliza and Alex broke out, and Winn and Alex left, Kara left to handle an emergency for Cat Grant. While there, Livewire arrived and attacked both Kara and Cat, with Kara causing Leslie to flee as Supergirl. Later, Kara discussed what had happened with Henshaw, who deduced that Kara was the Element X in Leslie getting her powers. Back in Cat's office, the two had a conversation about the death of Kara's parents, her current family problems, and Cat's problems with her own mother. Kara agreed to ask the FBI for a direct line to Supergirl, as well as taking Cat's offer to go home. At the D.E.O. Kara was given a industrial capacitor to capture Leslie with, and working with Cat, she was able to grab a water pipe under the street and short out Leslie with it. Before leaving, Eliza revealed to Kara and Alex that Jeremiah died working for the D.E.O., under Hank Henshaw.
Kara later broke up a road rage between two men, causing one of the men to confront her. Kara caught his punch, and twisted his arm, scaring children in the process. She was later criticized for her actions by both Maxwell Lord, and Hank Henshaw. Kara and Alex later persuaded Winn to hack into the D.E.O. mainframe to discover what had happened to Jeremiah Danvers. Both Kara and Alex were called by Henshaw, and at the D.E.O. base camp, General Lane arrived, demanding that Supergirl fight their field robot, Red Tornado. The next day, Kara as Supergirl flew to the D.E.O. base camp for her fight with Red Tornado. As the fight progressed, Supergirl lost her temper, breaking off Red Tornado's arm in the process. At CatCo, Kara lashed out at Cat, as she was frustrated with always being yelled at, despite working hard at her job. Kara and Cat later had drinks together at Noonan's, with Cat giving Kara advice on controlling her temper at work, furthermore find out why she was angry. Kara was alerted by James of Red Torando's appearance, with Kara arriving as Supergirl and engaging the android in combat. However, Kara had to diffuse a tornado Red Tornado caused, allowing it to escape. At a garage Kara and James blew off steam together, with Kara hitting a car, losing her temper, and soon after confiding in James that she thought she'd never find love or a normal life. At the D.E.O., Kara was informed by Alex that Morrow was still controlling Red Tornado. After the D.E.O. drew the robot out using hologram technology, Supergirl engaged Red Tornado and used her heat vision in an attempt to stop Red Tornado once and for all, causing the android to explode. While later cleaning up a glass from a cup she had dropped, Kara cut herself, much to her surprise.
She was later informed by the A.I. hologram of her mother, that her powers had been drained after she used the full power of her heat vision. Though she is told that her abilities should return in a few days, and Kara is urged by Alex to enjoy her day without her powers. Kara is later sent home by Cat for the day, when Cat sees her sneeze. She later encounters James, and a earthquake occurs soon afterwards, with a car almost colliding with Kara, and although James knocks her out of the way, she sustains a broken arm. After Maxwell Lord criticized Supergirl's absence, Kara and James visit him, with him claiming that Supergirl no longer has her powers due to her recent fight with Red Tornado and may never get them back. Back on the streets, Kara is present when Maxwell attempts to save a woman's father, though in the absence of an X-ray machine to find a venous thrombosis, he fails. Without her power of X-ray vision, Kara is unable to save the man as well, making her feel helpless. Kara hears a robbery happening nearby, showing up as Supergirl, and talking the robber out of it, with James snapping a photo of the event. She is later informed by Winn, that an adrenaline rush will restore her powers. After James almost falls down an elevator shaft , the moment allows for Kara's powers to return. With her powers back, Kara stops several disasters, including a bus of children from falling off a bridge, and a fire at West National City Bank. Kara was later told by Winn that he was disappointed in her, for her actions with James, despite him having a girlfriend. She later thanked Cat Grant as Supergirl for her actions during her absence, and while flying, Kara was attacked by three Kryptonians, led by her Aunt Astra.
Kara fights them off, and although Astra attempts to persuade Kara to join them, Kara refuses and leaves. She then returns to the D.E.O. to inform Alex and Hank, though they suggest she not rush anything, and get some rest. The following day, Kara is asked by Cat to bring in Winn and James for help after news broke of her leaked email server. At the D.E.O., Kara sparred with Alex, with the latter chiding her for hesitating during their session, and furthermore that she thought DEO should handle the Kryptonian threat, because of Kara's familial ties. Kara and James informed Cat that there wasn't anything in the emails that could be used to slander her, though Kara was later told by Cat to keep looking for any more leaks, as she suspected Dirk Armstrong was going to find some way to damage her reputation. Kara, using her hearing, listened to Armstrong admitting to having set Cat up. Kara then asked James to enlist Lucy's help in tracking a paper trail to clear Cat's name. Soon after Kara went to confront Astra, who had called her out publicly. During their battle, Kara eventually gains the upperhand, taking an unconscious Astra back to the D.E.O.. There, Kara discovers her mother used her to summon Astra in the past, to get the latter arrested. At CatCo, Kara learns about Adam Foster, an individual in Opal City Cat had been paying money to. She later finds out from Cat that Adam is her estranged son. Kara is later present when James, Winn, and Lucy arrived presenting her with evidence that Dirk was behind the leaks. Later, Kara goes to Cat, and is surprised to learn that Cat found out that she was Supergirl. During which, Kara gets a call from Alex, and excuses herself and arrives ready to battle Non.
During her fight with Non, Hank is abducted by Non. At D.E.O. headquarters, Kara asks Astra where Non took Hank, but she refuses to reveal anything. Kara tells James and Winn of Cat suspecting her to be Supergirl, a suspicion Cat continues to test through various challenges. Kara is present when Non contacts the D.E.O., offering to trade Hank for Astra. Much to her horror, Kara later has to sit by while General Lane tortures Astra with a Kryptonite injection. Kara later has to save Alex and another D.E.O. agent from an explosion after Astra's revelation of Hank's location turns out to be a trap. At CatCo, Kara is given the dilemma of proving that she isn't Supergirl, or Cat will fire her. Later, Kara thanks Cat for the opportunity to work with her and resigns, explaining that Cat's suspicions make it impossible for her to do her job. Afterwards, she discovers James' injuries that he had sustained, after investigating Maxwell Lord, announcing that she'd go after him. While visiting Astra, Astra tells her that going through with the exchange is the only way to rescue Hank. Kara agrees, though there is initial protest from General Lane. She is present when the trade is made, and though Non springs an ambush, Astra calls off the attack, demanding that Non honor the agreement. Hank later uses his shapeshifting ability to impersonate Supergirl so that Cat can see her and Kara at the same time, and Kara is offered her job back. Though Kara is offered full-time job at the D.E.O. by Hank, she rejects it because her relationships at CatCo are what humanizes her. She later has an online chat with Superman, who offers her both support, and assistance if she ever needs it.
During a flight together, Kara attempts to convince a reluctant J'onn to embrace his powers and reveal himself to the world. The two are then joined by Alex and the three come up with a plan to find out what Maxwell is hiding at Lord Technologies. Kara is later present when Agent Cameron Chase arrives to question him about his father's whereabouts. Kara then confronts Winn, who tells her his father's crimes, and Winn then shows Kara a doll he received on his desk, from Winslow Sr.. Later, Kara questions Cat's reason for hiring Lucy, only to have Cat accuse her of making a move for James. Kara goes along with Winn, when the F.BI. has him go to an arcade to meet his father, in a trap. She later saves several agents and Winn from poisonous gas, inhaling the gas and dispersing it into the air. Back at CatCo, Kara is informed that Winslow Sr. must be hiding in an abandoned factory that he use to own and Kara flies off to capture him before the FBI does. When she arrives at the factory Kara is trapped in a box of quicksand, and overhears a girls voice from an overhead box that is about to be dropped into a shredder. She escapes but discovers a Supergirl doll in the box, allowing Winslow Sr. to escape. At her apartment, Kara is kissed by Winn while the two were talking, though she rejects him. At National City Toy Con, Kara later saves Winn from being shot by several F.B.I. agents, and uses her x-ray vision to see Winslow Sr. set bombs on a timer. She turns on the sprinklers and freezes the water to create a frozen shield that protects the Con's attendees, foiling Winslow Sr.'s plans and subduing him. Later at CatCo, Kara tries to apologize to Winn, who in turn apologized for kissing her, though isn't sure where they stood because of his feelings for her. Later that evening Kara flies in with her Supergirl costume into her apartment, confiding to Alex about Winn's feelings for her and admitting she felt guilty about it.
Kara is later on the verge of being fired because Adam Foster arrives in National City, after receiving a letter written from Kara, who pretended she was Cat. However, Kara turns things around by offering to have the two dine together by getting them reservations. She later saves Senator Miranda Crane when a White Martian attacks the rally, and afterwards offers to J'onn to help take it down. Kara helps Cat out with getting to know Adam before their dinner, and is later shown photos by James of the White Martian's attack at the rally, who notices that some of them show Miranda's eyes glowing white—much like those of the White Martian. Kara calls Alex, telling her that the White Martian is at the D.E.O., disguised as Miranda. Kara shows up as the White Martian is about to attack, only for the White Martian to escape. At CatCo, Kara tends to Cat who is upset over the dinner earlier because of the letter, which prompts Kara to go see Adam personally. After a short talk and an admission from Kara about the letter, Adam agrees to meet with his mother on the condition that Kara joins them. During their dinner, Kara acts as a mediator and successfully helps mend their relationship. Later, Kara goes with J'onn to the desert to rescue Alex, and defeat the White Martian. During the battle, J'onn puts Kryptonite handcuffs on Kara so he can kill the White Martian, though Kara talks him out of it. At the D.E.O., Kara is thanked by the real Miranda Crane, and later Kara is asked out on a date by Adam, which she agrees to. At her apartment, Kara and Alex see a Supergirl impostor save a car from falling.
At the D.E.O., Kara suggests the impostor is a clone. Kara later notices Cat being nice to her because she was dating Adam. During her date with Adam, Kara sees a news report of a stranded tram, prompting her to bail. Atop the tram, she was confronted by Bizarro, who ignores her questions and attacks her. During their fight, they broke the tram's support, causing it to fall. Supergirl catches it while Bizarro watches in slight puzzlement. Kara is later asked out on another date by Adam, which she was convinced to go on by Alex. On their date, Adam and Kara discussed their parentage, and Kara said it's hard for her to feel normal, though Adam told her no one feels normal and the two kiss. During which, Bizarro swooped down and dragged Kara away. The two fought and Bizarro gained the upper hand until Alex arrived, fireing at Bizarro with Kryptonite weapons, causing her biological structure to mutate and decay. Bizarro screamed her hatred for Supergirl before flying off. Kara realized that Bizarro came after her in her civilian identity and deduced that Max knew her secret identity. Kara stated they need to stop Max once and for all. Back at CatCo, Kara broke up with Adam, citing she didn't have room in her life for him. She was later alerted to James' position after he had been captured by Bizarro. Supergirl and Bizarro fought again and the latter tried to strangle Supergirl, though Alex got a clear shot and knocked Bizarro unconscious. Supergirl later got an apology from Bizarro before she was put under. Kara later went to confront Maxwell, telling him he'd never hurt anyone again, before the latter threatened her foster mother, angering Kara. At CatCo, Cat told Kara she wanted their relationship to go back to being strictly professional. Kara was later attacked by a creature when she arrived back at her apartment.
Kara woke up on a bed and was surprised to find herself on Krypton, with her mother Alura claiming that Kara had been suffering from "Argo fever". She later panicked as she did not have her powers or didn't understand what was happening. She was distracted by a carving she made for Zor-El when she was eight, but was conflicted over her memory of leaving Krypton as well. She was determined to get to the bottom of the mystery and go home. Kara's memories of Earth later faltered, and she was finally distracted and placated by a young Kal-El, who asked her to open an intricate orb, which she did. The orb opened a large holographic display of the cosmos. With Kal-El pointing out Krypton and Kara quietly agreeing with him that it was beautiful. When Alex arrived in the hallucination, Kara knocked her out with a sculpture, having no memory of her life on Earth. Kara's memories were later jogged when Alex was being sentenced, and she was freed from the Black Mercy. After she awoke, Kara angrily demanded to know who had done it to her, and angrily confronted Non, pummeling him. She later spoke to Astra during her last moments, while she was dying. She later arrived back at her apartment, to find Alex, Winn, and James waiting for her.
Later at her apartment, Kara was summoned by Non to attend Astra's funeral. She was also told that there'd be a two week mourning period, and then Non would kill her. At the D.E.O., Kara refused to release Maxwell Lord, and the next day at CatCo, Kara was informed by Cat that she had hired a second assistant. After being one-upped by Cat's new assistant, Siobhan Smythe, Kara overheard Cat telling James and Lucy to investigate Maxwell Lord's disappearance. Soon after, Kara argued with James over the D.E.O.'s ethics, and holding Max without due process. She was later questioned by Siobhan about the nature of her and James' relationship via message, though Kara told her they were simply friends. She later confronted Master Jailer, eventually becoming entangled in chains, allowing him, along with the Fort Rozz escapee he was hunting, to escape. Back at the D.E.O., Hank identified the alien as Luzano, a former drug smuggler Alura had put away in the past. She was later once more confronted by James about the D.E.O.'s imprisonment of Maxwell Lord, though she told him that she did what needed to be done. Kara later discovered that Master Jailer was a police detective through Alex, and confronted him in his civilian guise. She was soon after captured by Master Jailer, finding herself in a cage without her powers. While there she talked with Professor Luzano, with him telling her, his story. The two however were saved by Alex and the D.E.O., and Kara was able to defeat Master Jailer. Kara and Alex later released Maxwell Lord, and later after unsuccessfully questioning her A.I. about Myriad, told Hank she didn't know how to work with him after what he had done to Astra.
In the days following, Kara rejected Alex's offers of coming back to the D.E.O.. She later prevents an accident, after a hacker who appears on CatCo monitors, disrupts the city's traffic signals. Back at her apartment, the hacker teleports through a computer when Winn attempts to crack the hacker's code. However, Alex and Hank arrive, and after making the hacker retreat, she rejects another offer to come back to the D.E.O.. Kara is later taken to Superman's Fortress of Solitude by James, where she questions Kelex, telling it that she's looking for a Coluan. Kelex tells her the hacker is Indigo, a descendant of Brainiac and a prisoner at Fort Rozz for attempted genocide, and is considered the deadliest of all the escaped prisoners. She later tries to talk to Lucy after she gets mad at James for missing their date, recounting a story James told her about how he got his camera. Kara later arrives at a military site to fight Indigo, who was attempting to launch nuclear missions at National City. However, she is forced to abandon the fight when Indigo activates a missile. She attempts to push it off course, but it simply adjusts its path and continues to fly towards National City. With Hank's help however, she is able to successfully disarm the missile. Indigo attempts to launch more missiles though Kara returns to stop her. She is later defeated for good, after being infected by a virus that disabled her. Kara later tells James that he can tell Lucy her secret, though he reveals Lucy broke up with him. Kara later returns to work at the D.E.O., with Alex coming clean about killing Astra, causing the two to embrace.
Kara is later infected with Red Kryptonite when she flies out to help a fireman trapped by debris in a fire. The next day, Kara smashes her alarm clock and arrives for work at CatCo wearing somewhat more stylish attire than normal. She later lets a K'hund Fort Rozz escapee go after defeating him, and afterwards criticizes Hank for hiding his abilities when him and Alex confront her. At CatCo, Kara gets Siobhan fired by luring her away from her desk long enough to print a copy of the email of her trying to sell the story of Supergirl letting the alien escape, to the Daily Planet. Kara invites Winn and James to celebrate at a club. Kara arrived late, and persuaded James to dance with her. She tried to come on to James, and trashed Lucy in the process. Kara later flies to CatCo, and tells Cat that she's no longer interested in being a hero. To prove her point, she throws Cat over the balcony, and flies down to catch her just in time. Later at her apartment, Kara adopts a new uniform, similar to what Astra and the rest of the Kryptonians wore, laying into Alex when she arrived, pouring out years of resentment. Flying off, Kara wreaked havoc on National City, causing Hank to reveal his true martian form, as J'onn J'onzz and engage her, allowing Alex to use an antidote on her. Kara is later horrified at her actions under the influence of Red Kryptonite, and attempts to soon after apologize to both James and Cat, though unsuccessfully.
Days after, Kara went to stop a bank intervention in the morning, though everyone fled when she arrived, due to her scaring everyone while under the influence of Red Kryptonite. She then took a sick day at work, and later fails at listening in on Colonel James Harper's interrogation of J'onn. Kara along with Alex later object when J'onn is taken into custody, though to no avail. She is later shocked, when Alex is also taken into custody, and the two are both being sent to Project Cadmus. Kara later has James explain what Project Cadmus is, and Kara is forced to reveal her identity to Lucy in an attempt to save J'onn and Alex. Both Kara and Lucy later break J'onn and Alex out while they were in route to Project Cadmus. Kara offers to hide Alex in the Fortress of Solitude while she finds Jeremiah, but Alex insists that she has to be the one to find him. Back at the D.E.O., she agrees to help Lucy, as Lucy is promoted to acting director of the D.E.O.. Upon being informed that a bank robbery is underway, Kara heads off to stop it. However, she didn't know if National City would ever trust her again, though Lucy reassures her that if she can win her trust, she can win back the city.
Kara along with Winn later took Siobhan to the D.E.O. after she had fell from a roof, and exhibited powers to save herself. Later at CatCo, Kara is sent flying out of the window by Siobhan using her sonic scream. However, she is caught by The Flash. After The Flash accidentally runs her to the desert, Kara flies off, though after stopping to talk to him, he explains that he's from another universe, and needs her help to get back. Kara introduces Barry to Winn and James, and explains the concept of the multiverse. She later enlists Barry to help her defeat Livewire and Siobhan, promising afterwards she'd help him get home. At the D.E.O., Kara introduced Barry to Lucy, and Kara later insists that the two subdue Livewire and Siobhan after the two were tracked down at an abandoned warehouse. However, the two are unsuccessful, and Barry later gives Kara a pep talk, telling her to slow down and stop trying so hard, as he went through something similar. At the D.E.O., Kara is contacted by James and told that Livewire and Silver Banshee have kidnapped Cat. Supergirl and The Flash arrive, defeating the two villains utilizing ear-bud type devices Barry had created, and with the help of National City citizens and the fire department. Later, Kara helps Barry get home by combining their speed in a race, with Kara throwing him through it. Later at her apartment, Kara and James shared a kiss, though afterwards she is surprised to see him walk away with a blank stare, and join hundreds of other people marching blankly down the street, all under the control of Myriad.
Kara arrives at the D.E.O., and attempts to stop a prisoner, Maxima, from escaping. However, Lucy stops her with Kryptonite bullets, though she is able to stop the rest of the prisoners from escaping by destroying the computer terminal, using the afterburners from her pod. After removing the bullet, she flies to the Fortress of Solitude to find her cousin Superman, but Kelex tells Kara that he is not on Earth and refuses to inform her about Myriad. However, the A.I. of Alura explains that Myriad was a mind-control system Astra and Non were arrested for trying to use against the people of Krypton, also learning Kara that once Myriad is in effect it can't be stopped. Back in National City, Kara is noticing everyone, even Winn and James, are now under the Myriad effect and watching Kryptonian codes on the screen, General Lane has placed the entire city under quarantine, but Kara informs him that she will help save his daughter. However, she soon finds out Maxwell Lord and Cat Grant are both unaffected, due to Max's technology. Non soon arrives, and forces James, Winn, and Kelly to jump to their deaths. Kara however is only able to save Winn and James. Soon after, she warns Alex not to come to National City, or else she'd be under the control of Myriad. She later agrees to go along with Maxwell Lord's plan, though Cat opposes to it. The two go to Lord Technologies to convince Lord not to launch his bomb, and the trio went to Cat's original broadcasting station intending to broadcast a counter signal to Myriad. However, Alex arrives under the control of Myriad, and in Kryptonite armor, engaging Kara in battle.
During the fight, Kara was swiftly defeated by Alex, and almost killed, until J'onn arrived with Eliza, who talked Alex out of it, breaking Myriad's control over her. In the broadcasting station, Kara successfully broke Myriad's control over the people of National City, by giving a speech about hope. Later at the D.E.O., Maxwell Lord informed them that the Kryptonians were now using Myriad, increasing the frequency until every human's cranium exploded. Before she could leave, Maxwell Lord warned Kara that this was in fact a suicide mission as she had no backup. After hearing such, Kara gave Winn, Cat, and James goodbyes of sorts at CatCo. She later, identified the device Maxwell Lord had discovered that was powering Myriad, as a Omegahedron, energy devices used on Krypton. After being informed that the Non and the Kryptonians were hiding out in Nevada in Fort Rozz, Kara went to confront them, along with J'onn who the D.E.O. agreed to release. Before she left, Kara gave Alex the necklace her mother had given her, to keep it safe. There, Supergirl and Non fought each other, and Indigo and J'onn battled one another. Kara eventually defeated Non in a heat vision face off, and a dying Indigo revealed that she had locked Fort Rozz's system, so they couldn't fly away the ship, which was powering Myriad. Kara decided to fly the ship into space, telling her sister goodbye over her intercom. While doing so, Supergirl went unconscious. However she was saved by Alex who used her pod to rescue her. Back at the D.E.O., Kara was congratulated, and the next day at work Kara received praise from Clark via message, and was promoted by Cat. Later at her apartment, Kara had a celebratory dinner, though it was interrupted when a pod flying in the sky caught their attention, causing Kara and J'onn. At the crash site, Kara recognized the pod as identical to hers, and was surprised at what she found inside.
Kara is kind, caring, selfless, intelligent, courageous, and has a sense of justice, honor and good morals. However, when she makes mistakes, she feels guilt and remorse for her actions. Due to her being a new superhero, Kara unfortunately does not have the confidence that her cousin Kal-El possesses. She is also short-tempered and sometimes lets her emotions get the better of her.
- Solar Empowerment: She needs solar energy or Sunlight to fuel her powers. Her powers would gradually fade away the more she uses her powers and if she doesn't replenish it regularly. Without her solar energies, her strength, endurance and powers will gradually decline.
- Superhuman Strength: She has the vast physical strength of a Kryptonian, enough to make humans condor them "Gods".
- Superhuman Speed: She can also move at high speeds and had a race with the Flash as well. Despite her great speed, she is not quite as fast as the Flash or other Speedsters such as the Reverse Flash, Kid Flash, Zoom, or Savitar.
- Near-Invulnerability: She cannot be harmed by weapons which can kill mortals. She is immune to illness and ailments. She is also impervious to trauma from most alien technological weapons. However, beings of equal power can damage them. Should they damage her, her increased metabolism ables her to use stored up solar energy to heal quickly. She can also eat a lot of food without gaining any fat tissues or health disorders.
- X-Ray Vision: She has x-ray vision and usually uses it to look outside her door from her couch. However, she is unable to see through objects made of lead.
- Heat Vision: She can also fire concentrated heat energy from her pupils. Depending on her anger, the power of the heat vision increases, but at the cost of her solar power reserves.
- Super Breath: She can also create powerful gushes of wind through her breath and even create ice.
- Superhuman Hearing: Her sense of hearing has also been strengthened to a great extent.
- Flight: She can use the stored solar energies to generate gravity field sound her enabling her to levitate and fly at high speeds if required.
- Master Combatant: Initially, Kara had no formal combat training and relied solely on her powers, but after a sufficient amount of formal training from her highly skilled human adoptive sister, Alex Danvers, she has become a highly skilled and powerful opponent, and as a result, she has been able to hold her own against enemies who are more or less as powerful and skilful as she is.
- Singing: She has shown to have a very beautiful and skilled singing voice.
- Dancing: She has also shown to be a skilled dancer, even tap dancing, just like her friend Barry Allen.
- Kara has excellent metabolism like her cousin Clark Kent aka Superman and Barry Allen aka The Flash. That is why she does not get fat despite eating too much sugary foods.
- Kara left Krypton when she was 13, she sailed through and stranded in Fort Rozz and got out and finally landed on Earth. She did not age because of her suspended animation; since it was 24 years later, Kara would have been 50 years old by then. Furthermore, Kryptonians has longevity means suspended animation. They will age, but they age slowly.
- Kara is the only main protagonist in the entire Arrowverse who is not from Earth 1, and the only one who is an alien.
- Although Kara is a very beautiful and very attractive being and thus many male characters, heroes and villains, have shown attraction to her (even the bisexual heroine Sara Lance has shown attraction to her), the handful of male characters who have shown either little or no attraction to her are J'ohn J'onzz (justified since he views her and her adoptive sister Alex Danvers as daughters and they view him as a father-figure), her "Superfriend" Barry Allen, Oliver Queen, John Diggle, Ray Palmer, Cisco Ramone, Wally West, Jefferson Jackson, Harrison Wells from Earth 2, Maxwell Lord, and Brainiac 5.
- She is similar and looks like Felicity Smoak and Chloe Sullivan. She is also similar to Willow Rosenberg from Buffy the Vampire Slayer.
- Kara is one of the very few, if not the only, heterosexual female character in the Arrowverse who is not attracted to Oliver Queen, despite him being an extremely attractive man. In "Crisis On Earth X", when she finds out that her Earth X counterpart, Overgirl, is married to Oliver's Earth X counterpart, Dark Arrow, she clearly states that she finds the idea of she and Oliver being together to be gross.
- Furthermore, Kara is the polar opposite to Oliver:
- Kara is an alien from Earth 38, while Oliver is a human from Earth 1.
- Kara has a vast array of superpowers that make her godlike thanks to her Kryptonian physiology, while Oliver has no superpowers thanks to his human physiology, but is still a formidable and experienced combatant that makes him quite dangerous to some aliens and metahumans.
- Kara is an outright superhero who inspires hope, optimism and warmth and is against killing, even though she has been tempted at times but ultimately restrains herself, while Oliver is an anti-hero vigilante who inspires darkness, realism and fear and is not afraid to kill, though he does not enjoy it and has taken on a no killing rule since the death of his best friend, Tommy Merlyn, in the Season 1 finale, until he goes back to killing in the Season 5 premiere.
- Kara does not wear a mask or a hood while she is Supergirl, but she wears thick glasses and pulls her hair back in a bunch while she is Kara Danvers to conceal her superhero identity, whereas Oliver wears an eye mask and a hood while he is Green Arrow to conceal his true identity as Oliver Queen. Also, on a minor note, Kara's hero outfit is red and blue, while Oliver's hero outfit is dark green.
- On another minor note, Kara can sing while Oliver either can't or doesn't want to.
- Also, all of Kara's enemies who are considered Pure Evil are female, while all of Oliver's enemies who are considered Pure Evil are male.
- Furthermore, Kara is the polar opposite to Oliver:
