Leonard Snart (Arrowverse)

"Leonard Snart, Robber of ATMS!"

- Leonard to Vandal Savage Leonard Snart, also known as Captain Cold or simply Cold, is a major antagonist, later anti-hero in the CW TV series The Flash, and a anti-hero/supporting protagonist in the first season of the spin-off series DC's Legends of Tomorrow, and a supporting antagonist in the second season. He is an infamous supervillain with a freeze-ray and seeks the thrills of robbing and killing, and works alongside Mick Rory in such crimes.

Appearance
Snart joined the "Legends" crew of Rip Hunter's time-ship, the Waverider, to save the world from Vandal Savage. He eventually sacrificed himself to save his teammates whom he had grown close enough to call friends, dying in redemption.

Later, the time-travelling Legion of Doom plucked a version of Snart from the timeline before he joined the Legends while his values were still firmly that of a supervillain. However, he was later mind-wiped and returned to the point in time he was taken from so that he could be recruited for the Legends of Tomorrow to live his journey to his heroic redeeming sacrifice, what the then-redeemed Mick Rory called, "a better man".

Snart was portrayed by Wentworth Miller, who starred with Dominic Purcell (Heat Wave in The Flash) in the TV series Prison Break as protagonist Michael Scofield. Miller had also briefly provided the voice for Deathstroke in Young Justice and portrayed Chris Redfield in Resident Evil: Afterlife.

Early life
Leonard's father was a corrupt police officer who frequently abused him and his sister Lisa. In 1975, he is a little boy going downstairs and happens upon an older version of himself from the future, whom he thinks is a friend of his father. As a child, he and Lisa were taken by their grandfather to a diner called Motorcar, which they would use to spy on police officers later on. He eventually dropped out of high school and started sticking up banks with a gathered crew. Every six months, Snart would case a place worth robbing in Central City and then leave after getting his target. He eventually landed on a list called Central City's Most Wanted.

While locked in a juvenile facility, he was jumped on by some guys with a shiv, but was defended by fellow prisoner Mick Rory, who befriended the scrawny teenager. After getting out, they started performing robberies and other illegal activities.

In 2013, Snart did a heist with Sam Scudder and Rosa Dillon; however, against Snart's orders, they refused to lay low afterwards. On December 21st, the night of the S.T.A.R. Labs particle accelerator explosion, Snart goes to a warehouse where the two were hiding out and confronts them about their behavior, bringing two henchmen with him. They start talking down to Snart and say that they will run Central City soon enough. Realizing that they are rebelling against him, Snart ends up having to point a gun at Scudder; quickly disarmed by Rosa, Snart and his henchmen fight back, with Scudder being thrown into a mirror. Upon seeing the particle accelerator explosion on the other side of the city, Snart and his henchmen flee rather than finish off Scudder right then and there. Scudder ended up being hit by the dark matter wave from the explosion, while Snart was unharmed.

Going Rogue
In 2014, Snart and his crew come to Central City to hijack an armored car in order to acquire the Kahndaq Dynasty Diamond destined for the city museum. They use a tow-truck to stop the car and open the doors by freezing it with liquid nitrogen and smashing it open. While two of his men guard the drivers, Snart enters the vehicle to steal the diamond but all of them are attacked by the Flash. During the struggle, Snart falls down and loses his mask, so Barry is able to see his face. Panicking, one of Snart's colleagues runs of and shoots one of the drivers, severely injuring him. Barry grabs the man and brings him to a hospital, thereby allowing Snart and his crew to escape. Back at their headquarter, Snart's henchmen spit out theories about the Flash, one even claiming that he is a drone. Snart however seems to be absent minded, claiming that the response time from the police should have been 182 seconds, rather than the 60 seconds the Flash needed. He also claims that the Flash is a human. When the henchman who shot the driver claims that he has enough and wants out, Snart shoots him, stating that if you're out, you're out for good. Snart then tells his men that they need to up their game.

To have a chance against the Flash, Snart visits arms-dealer Basil Nurblin whooffers him a fire-based weapon. Snart refuses to take it, since he did not need to heat things up, but slow them down. Basil then shows him a freeze-ray stolen from S.T.A.R. Labs, and upon hearing only Nurblin knows of the freeze-ray, Snart freezes Basil to death. He visits two tours around Central City Museum to get the scope on the Kahndaq Diamond, thereby catching the attention of the museum owner, Dexter Myles, who calls on Detective Joe West as Joe wanted to be told if Myles catches anything suspicious. Joe pursues Snart out of the museum, but realizing that he is being followed Snart freezes the road under a arriving police car and flees into a nearby theater to escape. Still pursued by West, Snart attempts to freeze West but Flash appears and gets hit by the ray instead. To keep the Flash busy, Snart shoots at various civillians around the area, forcing Barry to save them instead of attacking Snart. However, Barry is unable to stop Snart from freezing a security guard at the theater. While Barry laments not having been able to save the man's life, Snart leaves the theatre.

Back at base, Snart tells his remaining two men that tonight, they will steal the Kahndaq Diamond. The guys protest, since now the museum would be filled with police, but Snart claims that with a freeze-ray there won't be any problem to steal the diamond. His men still disagree and, knowing that Snart will kill them given the possibility, hold a gun at Snart's head before stating that they too are leaving him. Though Snart claims that he will kill them if he ever sees them again, the two men leave the headquarter.

At night, Snart once again enters the museum. After blasting a door with his freeze-ray, Snart manages to intimidate a security guard into fleeing and is able to steal the diamond without casualties. Having obtained the diamond, Snart heads to a nearby train station and, after a gunfight with Joe West and Eddie Thawne, is able to board a train. However, the Flash follows him and boards the moving train as well. Facing Snart, Barry claims that he should have picked a faster vehicle to escape but Snart claims that he is not escaping as the train is full of civillians he can hurt, knowing that Barry would be forced to save them. He then points his cryo-gun at the bottom of the train and shoots, causing the train to slowly derail. While Barry is forced to save every civillian inside, Snart jumps out of the train. After Barry has saved the civillians and falls to the ground exhausted, he is shot by Snart and frozen to the ground. However, before he can kill Barry, Cisco Ramon and the rest of Barry's team appears, claiming to be holding a freeze-ray (which was actually a vacuum cleaner with LED lights). Cisco forces Snart to give up and, after being called Captain Cold, Snart amusedly walks off, claiming that Barry won this round. When Cisco tells him to leave the diamond, Snart replies that Cisco should not press his luck.

After escaping, Snart meets Mick Rory and convinces him to step up his game as well now that their playground has been invaded by the Flash. He gives Rory the flamethrower that he took from Basil, thereby turning his partner into the super villain Heat Wave.

Revenge of the Rogues
Despite the blog done by Iris West containing photos of Flash, he is still called an urban myth. Knowing that the Flash would make it harder to do criminal operations, Snart schemes a way to get the entire world aware of Flash's existence. He lies to Mick, claiming that they are going to steal expensive cars from a garage when actually Snart seeks to fight Flash again. However, upon noticing that Flash is nowhere to be seen, he and Mick leave without any of the vehicles.

Their second attempt to make the Flash aware of their return to Central City is by stealing an expensive painting called Fire & Ice from Osgood and Rachel Rathaway (parents of Hartley Rathaway), which is worth $25,000,000. When the painting is brought to Star City from Paris, Snart arrives at the airport and invades the hangar. When the police arrives, Snart shoots at them with his cryo-gun but is uneffective as Cisco Ramon has equipped the CCPD with temperature proof shields. Snart calls Rory for help, who shoots his flamethrower gun at the officers. Snart tells Rory to ignore the cops but to await the Flash but Rory is too carried away to listen. This gives Detective Joe West the oppurtunity to shoot at Rory's flame gun, rendering it useless. Snart and Rory then retreat with the painting.

Back at their hideout Rory manages to repair his gun but Snart then aims his cryo-gun at Rory, furious that he once again lost focus. Snart claims that Rory is obsessed but Rory retorts that Snart is obsessed as well as all he now cares about is the Flash. Snart claims that the only person able to defy their weapons is the Flash and that they therefore have to kill them. He then gives Rory the oppurtunity to escape with the painting but offers him Central City if he stays. To show Snart that he convinced him, Rory burns the painting with his gun. Snart then tells Rory that the Flash is not so different from the two of them as he has partners too.

Together, Snart and Rory kidnap Caitlin Snow when she tries to enter her car. At Star Labs, Cisco finds out that Snart's and Rory's guns could cancel each other's effects should they cross streams. Before they can analyse more, Barry is called by Joe who tells him of Caitlin's kidnapping.

With Caitlin captured, Snart and Rory then send a message to the media, claiming that they will kill Caitlin should the Flash not reveal himself.

Snart and Rory meet the Flash on a street crossing. The street has been cordoned by police officers who now know that the Flash is real. Rory and Snart then attack the Flash while Barry tries to make them cross beams to cancel their guns out. While Barry fights, Joe and Cisco enter the warehouse to save Caitlin.

Eventually, Snart and Rory have the Flash on the ground. Believing themselves to be victorious, Snart and Rory shoot at Barry but Eddie Thawne, who has grabbed a thermo proof shield, shields him from the blast long enough for Barry to get up. Seeing it the only possibility to stop Rory and Snart, Barry lets himself be hit by both rays and walks on until he stands right between Snart and Rory. He then runs off, causing Snart's and Rory's beam to hit each other. The resulting blast knocks both criminals off their feet. Snart and Rory are then arrested by the CCPD. The cryo-gun and flamethrower-gun are then given to Cisco, who brings them back to Star Labs. On their way to Iron Heights, the prison truck containing Snart and Rory is attacked and both are freed by Snart's sister Lisa.

Rogue Time
Snart and Rory are eventually captured by mob boss Vincent Santini, who has once run Snart out of town for being troublesome. Santini demands to know what Snart is doing in Central City. Snart tells him that it is his city. He also tells Santini that he and his family better left the city to find another area for their crimes.

Santini stands up, asking what Snart would do if Santini refused. Snart says that in that case, they would all freeze or burn. Santini tells Snart that he heard about their guns, but that he also heard that they lost them. He asks Snart what he is going to do without his toys, only for Rory and Snart to break free and take out Santini and his men except one, whom Snart tells to run to the rest of the Santini's to tell them that there's a new godfather in town.

To get back his weapon, Snart sends his sister Lisa to seduce and kidnap Cisco. When Cisco arrives at their house, Snart blackmails Cisco into creating new freeze and heat guns, having Cisco's brother Dante as a hostage. Cisco tries to tamper with the weapon he creates but Snart notices and forces him to stop. When Lisa demands a gun for herself, Snart orders Cisco to create a gun for her that fits her personality.

With their new guns, Snart and his sister attack Santini's casino. The Flash arrives and brings the mobsters outside to save them from Snart. He then takes Snart's sister hostage to make him drop his new gun. However, Snart reveals that he has Cisco and thus orders Barry to free Lisa. Barry tells Snart to let Cisco go and Snart says that he will think about it before leaving with his sister.

Returning home, Snart states that he will let Dante and Cisco go if Cisco reveals the identity of the Flash to him. To save Barry, Cisco claims that Barry always wears a mask to which Snart replies by shooting his freeze ray at Dante's hands. When Snart threatens to go further, Cisco gives up and tells Snart about Barry. True to his word, Snart lets Cisco and Dante go.

Barry and his team find out that the reason behind Snart's attack on the casino was to trigger the relocation of the money outside the casino, according to protocol. Indeed, the money is brought outside in a truck. During the journey, the truck is attacked by the two Snarts and Rory. While shooting at the truck from his motorbike, Snart is grabbed by the Flash, who snatches him from his bike. This forces Lisa, who is sitting in the sidecar, to try to take over the wheel. The bike crashes nontheless, causing Rory to ride his bike right inside Lisa's.

Meanwhile, Barry releases Snart in the middle of a forest, claiming that they need to talk. Snart claims that Barry is in a bad position, as Snart now knows his identity. Barry says that he could put Snart into his meta-human prison so that Snart wouldn't be able to tell someone but Snart reveals that in this case, he wouldn't be able to stop the uplink he set from broadcasting the Flash's identity all over the internet. Barry claims that he can't allow Snart to just steal whatever he wants and advises Snart to get into another business but Snart claims that he is doing it for the adrenaline as well as for the money and would not want to miss it. He also claims that he can't leave Central City as it is his home.

To solve the problem, Barry convinces Snart that if he really needs to continue stealing, he could do so without killing anyone if he is really as good as he claims. Snart agrees to this, but Barry also tells him that if Snart ever goes near anyone of his team ever again, Barry would put him into the meta-human cell no matter to whom he reveals the Flash's identity.

Rogue Air
"It's true, I did. But here's the thing - I'm a criminal! And a liar. And I hurt people. And I rob them. What did you expect me to do, not be what I am? I saw an oppurtunity to turn things to my advantage and did. Who you're really mad at is yourself. This is on you, Barry!"

- Snart reveals his motivation to a defeated Barry When Harrison Wells, revealed to be Eobard Thawne, reactivates the particle accellerator, Barry and his team are forced to the meta-humans the imprisoned as they would be vaporised by the accellerator elsewhise. They decide to move them to the A.R.G.U.S. facility on Lian Yu. As the CCPD refuses to provide an escort, Barry is forced to team up with Snart. Initially refusing, claiming that the destruction of Central City is not his problem, Snart is convinced by Barry who tells him that he can hardly rob dead people. However, Snart demands all the intel and files the CCPD has on him as payment for helping Barry. Having no other choice, Barry accepts, deletes all digital files on Snart and steals the physical ones. When handing the files to Snart, they are destroyed by Snart's sister Lisa who joins her brother. Back at Star Labs, Barry's team is surprised to find out that Snart did not even tell his sister about the Flash's identity (having promised to tell no one).

The meta-humans are then knocked out by a gas and put into a modified truck. While Barry runs before the truck to clear the rode, Snart drives behind in his motorbike. They safely arrive at Ferris Airfield, but while they are waiting for the plane to arrive, the metas escape as the device preventing them from using their power fails.A fight ensues in which the Flash is knocked out and which ends by Snart shooting and killing meta-human Jake Simmons with his freeze-gun because Simmons owed him money. When Bivolo tries to use his powers on Leonard, he is stopped by Lisa who aims her gun at his head.

Snart then adresses the remaining metas, telling them that he made it possible for them to escape. He advises that any of them goes their seperate way, but tells them to remember who saved them from being shipped to Lian Yu. The metas then leave the scene. Snart returns to the injured Barry, who realises that Snart tampered with the truck. He furiously asks why Snart let the metas escape and Snart tells him that they now owe him and that this is more useful to him than the metas rotting away on Lian Yu. Snart and Lisa then drive off on Snart's bike, leaving it for Cisco to help Barry up.

Fast Enough
He is present somewhere in Central City as he looks up in the sky to see a black hole ravaging the city. The Flash and Firestorm are able to stop it, and Snart disappears for the next six months.

Family of Rogues
During a heist on Central City racetrack with Rory and Lisa, Lisa is knocked out and Leonard is kidnapped. To save her brother, Lisa visits the Flash, claiming that he owed her brother one because Leonard did not kill him at the airfield. Interested whether Lisa says the truth, Cisco locates Snart's cold gun and Barry heads to the building where he finds Snart in a office building stealing blueprints. Snart claims to be okay, but Barry realises that something's off. Snart then freezes Barry's body with his cold gun before his father Lewis enters the room. Lewis is impressed with Leonard freezing the Flash, claiming that he didn't have it in him. Lewis then tells Snart that they need to leave as they are behind schedule. They leave Barry behind, who uses a device in his suit to thaw the ice around him.

Back at Star Labs, Barry confronts Lisa with the truth. She initially does not believe him, claiming that Snart would never work with Lewis. Lisa then reveals that their father hit them when they were children and that both of them learned to despise him. Barry and his team decide to find out why Snart is with Lewis.

Barry next meets Leonard in his favourite restaurant. He tries to find out what's going on with Leonard and offers his help. Snart threatens to reveal the Flash's identity to the world if Barry doesn't drop it, but Barry tells him that he doesn't care.

With his father and his father's associate David Rutenberg, Snart plans a heist. Realising that his father's plan could mean that people had to die, Snart advises his father to make a different approach but Lewis merely tells him that there are casualties in their line of work. When Rutenberg starts arguing with Snart, claiming that his cold gun is the only reason they are bringing him along, Lewis kills Rutenberg by exploding the thermite in Rutenberg's head. When the body is found, Barry and Joe realise that Lewis must have injected Lisa with thermite as well to force Snart to come along. This is confirmed when they scan Lisa's head at Star Labs.

Again, Barry visits Snart, this time at his home. He reveals that he knows that Lewis is forcing him to work with him and tells Snart that his team is working on a way to remove the thermite bomb from Lisa's head. Lewis then enters the room, surprised to see Barry. Lewis asks who Barry is and Barry claims that Snart told him that they needed a new technician on the job. He also claims that he previously worked with Snart on the Kahndaq Dynasty Diamond heist. Knowing what Barry's up to Snart backs him up, claiming that he couldn't have done it without Barry. Lewis agrees to take Barry along and, much to Barry's surprise, reveals that the heist is starting right now.

At the building, the Snart's and Barry enter disguised as janitors. When the security guards at the receptions demand ID's Lewis gives them to the guards but they do not seem to work. Lewis slowly moves his hand to his gun. Seing this, Barry convinces the security guards to let them pass without ID's as otherwise the guards would have to explain to the management why the toilets are still overflowing.

When they arrive on the twenty-seventh floor, they spot two armed security guards. Leonard and Lewis argue as Lewis was wrong about the timing. While they do so, Barry quickly gets the security guards out of the way behind their backs, claiming that they must have taken a break. Arriving at the vault door, Barry manages to breach the security code. However, after he is finished Lewis then shoots Barry as he no longer has need of him. (Barry survives because he was able to catch the bullet fired at him and fakes his own death). Watching this, Snart is visibly distraught and quietly apologises to Barry.

Inside the vault, Snart uses his cold gun to freeze the lasers. While his father opens the safe and bags the loot, Snart waits. Both are then confronted by the Flash. Lewis draws the trigger for the bomb inside Lisa's head, ordering Snart to shoot the Flash. When Snart hesitates, Lewis tells him to shoot or he will never see his sister again. However, at that moment Cisco manages to get the bomb out of Lisa. When the Flash tells Snart so, he instead aims his gun at his father's heart and shoots him. While dying, Lewis distraughtly asks Snart why he worked with the Flash, as he though Snart hated him. Snart cooly tells his father that he hates him more, before Lewis' heart stops.

Snart is arrested for murder and imprisoned at Iron Heights. There he is visited by Barry who states that he finally found out Snart's secret - that he would do anything for his sister. Snart responds that he knows Barry's secret as well and that Barry better hoped that Snart wouldn't talk in his sleep. Barry tells him that there is still good in Snart and that one day, Snart would come to see it. Snart is then brought back to his cell and Barry goes to Joe, who tells him that the paperwork for putting Snart into Iron Height's meta-human wing is already on his way.

Running to Stand Still
During the christmas season Mark Mardon attacks the prison. He frees Leonard Snart who, despite Joes intentions, was not imprisoned at the meta-human wing. The two then enter the Trickster's special cell and Mardon frees him as well.

Mardon brings Snart and Jesse to an abandoned toy factory. He tells them that he broke them out to kill the Flash, confident in their numbers, different skills, and knowledge of Barry's vicious defeat at Zoom's hands, leading him to believe the Scarlet Speedster is weak and vulnerable. Snart demands to know the plan first but Mardon refuses to tell, wanting to know whether Snart is in first. Both almost attack each other but Jesse defuses the situation.

Unwilling to side with Mardon and Jesse, Snart heads to the West house and waits for Barry to arrive. Though Barry is initially hostile, Snart reveals that Jesse and Mardon are coming for him. He then leaves the house without giving him more information.

Pilot, Part 1
While Snart and Mick were robbing a warehouse, he is unexpectedly interrupted by time traveler Rip Hunter, who knocks him and Mick out and taking them up atop a building in Star City to be briefed on an important job that must be done; join him on his mission to defeat the immortal tyrant Vandal Savage, who has taken over the world in 2166 and must be brought down on an epic time-travelling journey. Though Snart is rather reluctant to go with Hunter, as "hero ain't [his] resume", he is convinced otherwise when he concludes that he could travel through time and steal history's most notable artifacts and acquire higher finances. He talks Mick into accompanying him to an address in Star City where Rip awaits with the Waverider, his time-machine. Inside, all the heroes meet and converse (Sara Lance/White Canary, Martin Stein + Jefferson "Jax" Jackson/Firestorm, Kendra Saunders/Hawkgirl, Carter Hall/Hawkman), and journey to an unspecified date in 1975, where they intend to meet with the son of Hawkman and Hawkgirl's previous incarnation's son Aldus Boardman. While waiting for Stein, Kendra, Hunter and Hall to return to the Waverider, Snart, Mick and Sara leave and go into a bar, starting a bar fight. In addition, Chronos of the Time Masters (who Snart jokingly calls "Boba Fett") attacks the Waverider looking for Hunter, and thus all the heroes appear and fight him off. After escaping into a "time limbo" via the Waverider, Hunter explains to the heroes that they weren't actually legends in the future he is from and that he STOLE the Waverider to accomplish his goal, seeking revenge on Savage for killing his wife and son. The heroes are then discouraged from their supposed goal, but are re-motivated when reason and logic comes into play.

Pilot, Part 2
The LoT are brought to Norway (still in 1975) to hopefully strike at Savage when he's at a weapons auction, where all of history's dictators at the time were bidding millions of dollars to get their tools of genocide (Damien Darhk is also in attendance, and called "the master race" by Mick, referencing Adolf Hitler and the Nazis). However, it turns out that Savage is the guy SELLING the weapons, and so our heroes end up blowing their cover when they are forced to battle security, preventing the element of surprise from being on the side of the LoT. Firestorm stops a nuclear bomb from going off and obliterating the area, but that doesn't make up for the fact that they all have lost their advantage over their enemy.

Nonetheless, news comes in about an ancient dagger that was affected by the meteorites in Ancient Egypt that gave Savage immortality; however, it is being held in a mansion that is heavily-guarded. Snart, Mick and Jax break into the place, but are caught by a metal cage when Snart's intent to steal more stuff kicks in. After the rest of the LoT save them and Vandal succeeds in killing Carter and almost killing Kendra, everyone decides to stay on the team to avenge Carter.

Blood Ties
When Rip and Sara leave to weaken Savage by going after his finances, Snart and Mick talk Jax into letting them use an escape pod-like shuttle on the Waverider. They use it to venture to Central City 1975, where Snart steals an emerald that his father intended to steal previously. As it turns out, he intended to give it to his father in the past so that he won't live to become the abusive man he remembers; this leads Snart to his childhood home with the emerald in hand as he tells his younger self to stay strong and get through the tough times ahead, but then Lewis appears and tells young Snart to go upstairs. Older Snart gives Lewis the emerald and tells him that he would've killed him for his abusive nature, but he is needed alive so his sister can be born, confusing Lewis, as he wasn't being told who this guy really is or what he wants. Afterwards, he, Mick and Jax save Rip and Sara from Savage when they are performing a blood ritual to extend the life-span of Savage's followers (using Carter's blood, which counted as desecration). Though Snart believed that he had made his life better by saving his father, he later discovers that the timeline has a cruel way of correcting itself; Lewis was later arrested for trying to sell the emerald shortly after it was stolen, and thus he is incarcerated and the timeline is corrected. Though this was a sad moment for him, Snart didn't let it show. The team is then taken to another time period; 1986.

White Knights
In Washington D.C. 1986, the team organizes a break-in at the Pentagon, acquiring a document that led them to the Soviet Union to find Savage, but everything seems to go wrong as the team is tempted in all the wrong ways to screw up. The document leads them to investigate a case of nuclear scientists disappearing that are supposedly linked to Savage. On the way to the Soviet Union, they are attacked by Chronos, but Soviet fighter jets manage to shoot him down in addition to the Waverider. Though Ray attempts to win over Soviet scientist Valentina Vostok using his "charm", he is cruelly rejected by her; however, Snart not only wins her over but is also offered a date! When it is discovered by Stein that Vostok is working for Savage and intends to create her own version of Firestorm, Snart shows up with the others to save the day, but Ray, Stein and Mick are captured by the bad guys and placed in a gulag.

Fail-Safe
Snart commands an elaborate escape plan for the captured heroes, who are being faced by Savage at this moment, but it seems that Snart is showing more concern for Mick than the other heroes (he says "this ain't [his] first prison break", a reference to the show Prison Break that the actor starred in). Once the breakout finally comes underway, Snart succeeds in finding Mick, but finds that he won't leave without Ray, as he has apparently bonded with him. When Stein is unwillingly merged with Vostok and transformed into a Soviet Firestorm, Jax manages to get them apart, with everyone getting away in the Waverider as Vostok explodes like a nuclear bomb. While in the time limbo realm, Chronos attacks and gets the Waverider crashed into an alternate future for Star City in the year 2046, where various areas have been destroyed by fires and gang warfare. A new person under the Green Arrow mantle attacks the LoT, not knowing who they are or what they intend.

Star City 2046
After facing this different Green Arrow, the team retreats back to the Waverider. Snart, Rip, Mick and Sara head to Smoak Industries to find an essential piece of technology they could use to repair the ship, but Mick is distracted by how beautiful the sight of the burning city is. After he kills a random gang leader and takes his place, Mick is treated by his underlings like a king and he decides to stay in this future, which Snart wasn't intent on doing. He attempts to talk his partner out of this course of action, as that would mean he'd be stuck with the villainous Grant Wilson as his superior, but it seems that the hot-head has made up his mind; realizing that he won't come willingly, Snart has to knock him out and take him back to the Waverider unconscious. After the LoT saves Green Arrow, who is actually Connor Hawke/John Diggle Jr., from Grant, Snart assures his partner that his course of action was for the best, but Mick refuses to care about that, thinking that his life would've been perfect had he been left behind.

Marooned
Savage's trail goes cold, which worries Rip. Needing to give the Waverider's AI Gideon a "software update", he takes it into space and answers a distress call from another time ship called the Akeron, which has been seized by time pirates led by John Valor. The pirates fire at the Waverider, forcing Sara and Snart to rush down to the engine room and fix the hole in the wall. With the doors shut due to the hole being there and the new ice wall Snart made not lasting long, Ray has to prep the Atom suit for space-travel to save them. Snart tells Sara about how he met Mick in a juvenile facility and how they've got each other's backs since that day, but this is cut short when Mick makes a deal with the pirates to seize the Waverider for them. As such, the LoT defeats the pirates and Mick is to be punished for betraying them; Snart agrees to handle it.

Marooned/Left Behind
Sometime later back on Earth, in a grassy meadow at night (time period unknown), Snart explains to Mick why he must be put down. Though Mick believed that his betrayal was something that had to be done, Snart wouldn't listen. He then proceeds to fire his freeze-ray at Mick; however, instead of hitting him, he intentionally missed, allowing him to simply knock out Mick and leave him in this time period.

Night of the Hawk
In 1958, Snart and Rip pose as FBI agents in order to investigate the disappearances of teens throughout Harmony Falls, Oregon as they have been abducted and injected with a substance from a blue meteor rock that was responsible for giving Carter, Kendra and Savage their powers, but has turned the teens into demonic, hawk-like creatures. While in The Waverider, Jax launches into a rant about how everyone is acting like Mick was never a part of the team and wonders how Snart could ice his own partner. When the Harmony Falls Psychiatric Facility is attacked by the hawk creatures including a now mutated Jax, Snart helps Stein subdue Jax during the struggle and brings him to the Waverider to be turned back to normal with a substance created by Stein, who in turn thanks Snart for his heroism. After awakening, Jax apologizes to Snart and understands he had to kill Mick to protect the team and that he's not a monster. Out of nowhere, Chronos attacks Rip, Snart, Jax and Stein inside of the Waverider and they are forced to flee 1958, leaving Ray, Kendra and Sara stranded in the past.

Left Behind
Snart is captured by Chronos and brought on-board his time-ship. Handcuffed to a railing, Snart demands that Chronos tell him why he was captured and not simply treated like trash. This leads to Chronos unmasking himself, revealing that he is in fact Mick Rory, who had been found by the Time Masters and trained by them at a place called the Vanishing Point. Mick stated that he wanted revenge on Snart specifically, and intended to do that by killing Lisa again and again and again through time-travel, all while making Snart watch. Mick left later to go handle the rest of the LoT, allowing Snart to try and escape. He makes his way across the railing, knocking over his freeze-ray; he then activates the freeze-ray, freezing his hand off as he screams in pain. However, at least he was free, so he escapes the ship and goes into the League of Assassin's hideout in Nanda Parbat, where Mick was now. After he was defeated, Snart insisted that his mask be removed, revealing to the others who Chronos really is. Back on-board the Waverider, Mick is imprisoned.

Progeny
In 2147, where the Waverider is now, the LoT are briefed by Rip on the statues of the world in this time period. Savage, now tutor to the Hitler of the future Per Degaton, will manipulate Per into unleashing the Armageddon Virus upon the world, and as such, they must find out how to stop this. Snart seemed pretty content with killing "baby Hitler", as the world wouldn't be in danger from him or Savage if they did so, but the others were rather reluctant to this course of action. They then decide to kidnap him and put him on the Waverider. Shortly after this, they find that Rip has taken Per and is going to kill him; however, he ends up having to hand the body over to his father, as he would be resorting to Savage's methods to stop him. After the exchange, Snart returns to the Waverider and faces Mick, still in the holding cell. They fight each-other with their fists, but Mick spares Snart. He then informs everyone of the Time Master's new plan; to send the Hunters after the LoT, as he had failed to bring them all in.

The Magnificent Eight
Now hiding from the Hunters, the LoT arrive in 1871 and leave the Waverider to go explore to American West as it was in the cowboy years. While in a bar, when Stein was playing cards with someone who was losing, the guy stood up and whipped out his gun. Suddenly, the sound of a gunshot rings across the bar and the guy drops dead; Snart was sitting smug in a chair, his pistol having just let off lead into the man's chest. A barfight broke out, which is broken up by outlaw Jonah Hex, who judges the LoT as new around these parts. Outside the bar, Hex asks them about Rip Hunter, which shocks them; as it turns out back on the Waverider, Rip's time in the American West had led him to meet Hex before, and he had to tear himself apart from the beautiful time to keep his life as a Time Master existing. As it turns out, the guy Snart killed back in the bar was part of the Stillwater Gang, who would be coming to avenge their fallen comrade.

When Palmer is unwillingly named the sheriff of the town, he threatens the Stillwater Gang to back off or be killed on the spot; Snart was on a rooftop with a sniper rifle, aiming at them. When Jax is kidnapped by them, Rip comes to save the day, shooting the gang leader and saving Jax. However, at that moment, the Hunters appear, and everyone must get out their modern-day weaponry to beat them. After the Hunters are defeated and everyone returns to the Waverider, Mick informs everyone that the Time Masters have initiated the "Omega Protocol", and their younger selves are now in danger from the assassin known only as the Pilgrim.

Last Refuge
With the threat of the Pilgrim hanging over the Legends' heads, Rip is forced to have the team kidnap younger versions of themselves and hide them at a Time Master training house in London, where they learn that Rip's real name is Michael. Eventually, the Pilgrim gives Rip a deal; bring his younger self to her, or she'll keep hunting them. The idea was that, if Rip's younger self died, then the team will never be formed. However, while at an aircraft hangar to confront her, the Pilgrim fights back at the team, freezing them all in place with her time-altering powers. Young Rip sneaks up on her and stabs her, allowing Snart's freeze ray, Firestorm's fire and other team weapons to reduce the Pilgrim to a pile of ash. Realizing that there would be more assassins after their younger selves soon enough, Rip decides to head straight to 2166 before time cements itself and their younger selves are permanently erased from the timeline.

Leviathan
In 2166, days before the Second Blitz in London that claims the life of Rip's wife and son and 19 years after Savage releases the Armageddon Virus and has Per Degaton blamed and killed for it, the Waverider, now having arrived at the correct time period gets hit by a giant robot known as the Leviathan, crashing them to the ground. The team then heads for a city where Savage is shown giving a speech to his subjects alongside his daughter Cassandra Savage. During this, the team attacks; after noticing her strange bracelet, the team concludes that it is made from the Nth metal of Thanagar, the alien planet responsible for the immortality of Savage and the reincarnation of Khufu and Chay-Ara. They are forced to flee after this; Mick and Sara try to steal the bracelet, but end up kidnapping her instead and bringing her back to the Waverider.

She finds herself far away from her father and is now the team's hostage, locked up in the back of the Waverider; she reveals herself to be Savage's daughter and makes threats about what he'll do when he finds out where she is. Snart takes an interest in her and tries to tell her that Savage is a bad person, telling her about his own father and how much he hated him and thought of him as a monster. She doesn't believe him, as he had always told her that the Armageddon Virus, which had claimed her mother's life, had been released by Per Degaton and Savage killed him in order to "re-unite" the world's devastated nations under his own flag. Thinking that what her father was doing was good and just, Cassandra dares Snart to torture her, at which point he leaves her alone.

To back up his claims about Savage and the Virus, Snart lets out Cassandra and shows her a group of refugees that they had to save from Savage earlier; all of them were in terrible condition, with some starved and others sick and dying, with Snart trying to make his point about the so-called "resistance" against Savage. Still not convinced, Cassandra refuses to accept it; Snart then gets Gideon to play security camera footage from the Kasnia Conglomerate board room back in 2147, where he is shown discussing his plans for the Virus. Horrified, Cassandra returns to her father, having been let go by Snart, and confronts him about his actions. The team then arrives to kill Savage, with Kendra wielding a mace empowered by the Nth metal bracelet that Cassandra had on her; however, she decides not to kill him after discovering that he has been keeping the current Khufu incarnation alive as his soldier. Savage is then brought onto the Waverider, captured at last. Snart then leads Cassandra to the leader of the resistance against Savage and convinces him to let her join, as she has seen what evil her father has wrought. Snart leaves on the Waverider with the rest of the team (the Khufu incarnation as well), then head off into the cosmos to decide what to do with the villain.

River of Time
While in the Waverider as it flew through time, the team learns something interesting about the Leviathan robot that Ray destroyed while in 2166; the technology used in its construction originates from a point far later in the future than it should be. Rip becomes hopeful, now able to show the Time Masters that Savage had somehow manipulated time in order to obtain the technology for the Leviathan, and proceeds to fly the ship to the Vanishing Point, where Mick was brought by the Time Masters previously and turned into Chronos. However, Savage's presence on the ship, even if he's locked up, starts to get to some of the team, who all have their own idea of what should be done. Snart and Mick in particular tell Rip that it would be preferable to kill him and be done with it, but Rip says that doing so would alter the timeline too much. The duo debate leaving the team and getting back to their old lives in 2016, as Mick seems to want that, having had enough of all this and knowing that the Time Masters will kill him for betraying them. Snart also discusses the situation with Sara, who seems to like him; he even confesses straight to her face that he is attracted to her.

Jax, meanwhile, ends up getting blasted in the face by "time radiation" after fixing the damaged time drive, forcing Stein to take him to the jump-ship and send him back to 2016 in order to save him. Savage eventually manipulates Mick into releasing him, at which point he heads for the bridge, but Kendra heads him off. The Khufu incarnation, named Scythian Torvil, suddenly remembers all his past lives and who he really is; he attacks Savage and defeats him, bringing back to his cell. Rip then lands the Waverider at the Vanishing Point and brings Savage before Druce and the other Time Masters, hoping that the evidence of Savage's time alteration will hold up; however, the Time Masters instead let him go, much to Rip's horror, revealing that the Time Masters were Savage's secret benefactors, providing him with the Leviathan technology on purpose so he can fulfill his destiny to take over the world. Rip, Ray, Stein and the others are taken to prison cells on-site so that they won't be able to stop Savage.

Destiny
Sara and Snart, still on the Waverider, manage to hide from the Time Masters and must devise a way to save the others. To make sure they can't be pursued once they finally jump ship, the two go around the Vanishing Point time-ship hangar and quietly sabotage all the other time-ships there. Upon reaching Rip and the others, they free them from their cells; however, Mick has been taken away by Druce so he can hypnotized and turned back into Chronos. Rip reveals to the team something horrifying that Druce showed him; that the Time Masters orchestrated everything, from Savage obtaining the Leviathan technology to his world-domination scheme, to even the formation of the team and the deaths of Rip's wife and son. Druce has a machine known as the Oculus, a time and reality-altering machine that he used to assist Savage as well as peer into the future; in the year 2175, the Thanagarian alien race will invade Earth and destroy all life on it. To prevent this, Druce and the other Time Masters used the Oculus to alter reality so that Savage is able to take over the world in 2166, thus building up the power needed to fight them off and defeat them.

Back on the Waverider, the team debates what this means for them, now aware that they had no free will at all and the Time Masters made them do everything they've ever done. They decide to destroy the Oculus, which would rid the Time Masters of their powers and give them free will again, thus standing a chance against Savage, who has made off with Chay-Ara and Khufu in a jump-ship back to 2166. Ray, having been told that he'd die soon while trying to stop the Time Masters, decides to fulfill his unhappy destiny. Snart and Sara begin to wonder about each other and what the future holds for them, and ultimately kiss. The team then heads for the Oculus, but find that it is heavily-guarded, with Druce and several soldiers being present to stop them. However, Jax, having returned from 2016 in a jump-ship, arrives and fires lasers down on the soldiers, allowing the team to get into the Oculus power source room. Ray finds that the generator for the Vanishing Point has a fail-safe built into it to prevent its own self-destruct, and the only way to disable it is for someone to stay behind and hold onto the fail-safe; however, the explosion would end up killing anyone who is stupid enough to try it. Ray places his hand in the generator in order to keep Rip's vision on track; however, Snart tried convincing him to not do it. Realizing that he wouldn't listen, Snart knocks out Ray and puts his own arm in the generator, telling everyone else to go now while they can, effectively giving up his own life to save the others. The team escapes on the Waverider, while Druce enters the generator room with the other soldiers. Druce tells Snart to stop this; Snart defiantly tells Druce "There are no strings on me" (Pinocchio's infamous line) and stays. Seconds later, the generator explodes, killing Snart, Druce, the guards and most, if not all, of the other Time Masters and effectively destroying the Vanishing Point.

Legendary
Mick, mourning Snart, is returned to 2016 by Rip along with the rest of the team. However, he ends up assisting the others in finally taking down Savage, having been inspired by Snart's heroic death to do so. After managing to kill Savage and save the world, the team takes Mick to a point in 2013 to meet Snart again. Snart, shown to be drinking in a bar, is given an affectionate good-bye by Mick, unaware of what he's talking about, as he hasn't been recruited into the Legends yet.

The Chicago Way
In 1927 Chicago, Illinois, Mick, on the Waverider, continues to get himself drunk. After a certain amount, he ends up seeing a hallucination of Snart standing before him, who tries to convince him to return home to Central City and continue being a criminal. Mick, concerned, attempted to get Stein to examine his head, thinking that a device implanted in his head by the Time Masters during his time as Chronos is causing this. However, Stein concludes that the device hadn't been on for quite some time. It is still unknown if this is the real Snart or a hallucination.

Fellowship of the Spear
In 2014, before the Legends are formed, Snart is confronted by the Legion of Doom (Eobard Thawne, Damien Darhk and Malcolm Merlyn), a time-traveling group of super-villains attempting to acquire a reality-warping artifact known as the Spear of Destiny in order to change their fates. They tell Snart about his imminent demise trying to protect the Legends; Snart, having no real conscious at the time, decides to help them acquire the Spear and joins them without hesitation.

In 1916, during the Battle of the Somme in World War I, Mick disguises himself as a soldier in order to get into a camp. He ends up being confronted by Snart, believing him to be a hallucination again; Snart uses this to his advantage, tricking Mick into telling him where the Spear is. Mick ends up revealing the Legends' plan to use the blood of Christ to destroy the Spear, with Snart mocking him for attempting to destroy the greatest prize in the universe. Telling Mick that the Legends saw him as a brainless thug who cannot be trusted, Snart punches Mick in the face to prove that he is not an illusion and leaves, telling the Legion what the Legends are going to do.

The Legends then find Sir Gawain's map to the blood of Christ, which is built into the walls of a church in the midst of the battle. Snart appears before the team, revealing himself as real, while the Legends blame Mick for telling him what they were doing. Snart and Darhk, entering the church as well, summon German soldiers to attack them. While the Legends escape, Snart tells Mick that the team doesn't appreciate him. The Legends manage to temporarily call an armistice so that soldiers on both sides can collect their dead and injured, making the Somme field not so dangerous. The team acquires the blood of Christ, as well as bringing the Spear with them, but Snart and Darhk appear before them and demand that they hand over the Spear now. When they refused to, Snart declares the armistice over and throws a grenade into the air, resulting in the Battle of the Somme to resume abruptly. Mick decides to go with the Legion, realizing that Snart was right about them. Eobard arrives and speeds them away while the Legends escape from the battle. At the Vanishing Point, destroyed by the future Snart and used by the Legion as their hideout, Snart, Eobard, Darhk and Mick surround the Spear, while Malcolm arrives with a manuscript called the Calebros Maunscript that could activate its power. The five villains all grab onto the Spear as Malcolm speaks the words of the manuscript, activating the Spear's power and causing reality to be altered to suit their desires.

Doomworld
Reality has now been altered into a drastically-different one, one in which Damien Darhk is the mayor of Star City, the Flash, the Green Arrow and other vigilantes, good or evil, are dead, Malcolm has his family back and Eobard is a renowned scientist running S.T.A.R. Labs who has found ways to fix all the world's problems. Snart and Mick have returned to robbing banks; however, while they hit a bank in Central City, Snart tells the police to back off, which they do without hesitation. Mick found this to be anti-climatic, as it didn't make sense to continue being a criminal if no-one is going to stop them. Eobard summons them both to S.T.A.R. Labs, where he tells them about Malcolm and how he may end up being a threat to the sustenance of this reality. While they talk, Nate Heywood (a member of the Legends in the original reality) enters and tells Eobard that reality is not the way it should be; if nothing is done, then the universe could unravel and all that is will perish. He has come to Eobard because his scientific prowess would be able to fix this. Eobard, concerned that Nate will learn more, tells Mick and Snart to take him somewhere far away and kill him so no-one finds his body.

Personality
Leonard Snart is first and foremost a man who plays by his own code and is drawn to the lifestyle of a thief, as he longs for a sense of freedom and to be unbound by the laws of society. Ultimately, Leonard is more driven by the thrill of the chase rather than the actual catch and shows signs of being an adrenaline junkie because of this. Presumably because of his traumatic and abusive childhood, Snart carries out everyday with his self-taught philosophy that the only person who is going to look out for his own well-being was himself. Also, he detests being thought of as having morals or heroic in any sort and after his sacrifice to save his team Ray Palmer states he died a hero, which was "the last thing he wanted to be known as".

Despite this Leonard Snart is actually a good man, if not a grotesquely flawed one. Though his sense of morals is dubious to say the least it cannot be denied that Leonard is an honourable man, and a surprisingly altruistic one (should the situation call for it). For example he does his best to avoid casualties unless absolutely necessary while robbing and even warned Barry Allen of James Jesse and Mark Mardon's plans to kill him despite being enemies. The greatest display of Snart's character is when he sacrificed his own life so that Rip Hunter's team could escape.

When Leonard sets his mind on a goal he will go to incredible, immoral lengths to achieve it. He is extremely obsessive and single-minded in this regard, for example when recruited Mick Rory he focused solely on killing the Flash rather than stealing despite being granted numerous opportunities, once he passed off walking away with a dozen expensive cars solely so he could draw out the Flash and when he didn't he just drove away which greatly irritated his partner. While planning a heist, Snart is calculating, meticulously thorough, patient and flawless in detail. He is a man who makes very few mistakes and expects his men to follow this. He was also clever enough to deduce that the blur that attacked his heist was a man and used this information to choose the perfect weapon to counteract his speed - the cold gun.

In spite of his cold, ruthless, sociopathic nature Leonard is very affectionate towards his sister, Lisa even if they do tease each other a lot. He will do anything to protect her, even working with his much-hated father, Lewis when he blackmailed his own son into working with him by implanting a bomb in Lisa's skull and later shooting Lewis without remorse when Lisa was safe.

Snart prides himself on being the man was doesn't play by the rules and is very against being controlled or manipulated. For example after being forced to work with his father, Lewis when the latter blackmails him, the second he lost his leverage on Leonard he killed him on the spot. He was also left extremely disillusioned when he discovered that the Time Masters have been controlling his and the rest of Rip Hunter's team from the very start, as if every action he followed was from some sort of script. To prove himself that he's not a puppet however he defies the Time Masters by sacrificing his own life when it was actually Ray Palmer's destiny to die saving the team and assures himself he follows his own path rather than the one that has already been decided from him which he reinforces with his final words being "there are no strings on me", a reference to Pinochio.

Trivia

 * Almost all episodes of The Flash in which he appeared had the word "Rogue" in it; this is because of the character's comic-book status as the leader of the Rogues, a supervillain team that opposes the Flash.
 * Wentworth Miller had pitched Snart as pansexual to the writers; if he found someone with the right amount of wits, charm and badassery, he'd be into them, and gender would be completely-irrelevant.
 * In the DC's Legends of Tomorrow episode "The Magnificent Eight", a man in a bar is about to shoot Stein to death, but instead, Snart manages to shoot him instead. This scene mirrors an infamous scene in the original Star Wars, when Han Solo kills Greedo before he has a chance to fire. Similarly, Snart has his feet on a table, like Han Solo did in that scene. It can also be taken as a reference to the Dollars Trilogy of spaghetti Western films.
 * Snart mentions in the DC's Legends of Tomorrow episode "Fail-Safe" that "this ain't [his] first prison break", a reference to Wentworth Miller's role as Michael Scofield in the FOX TV series Prison Break. In the show, Scofield attempts to break his brother Lincoln Burrows (played by Mick Rory's actor, Dominic Purcell) out of Fox River State Penitentiary.
 * In addition, William Tockman, a brief antagonist in the other Arrow-verse series, is portrayed by Robert Knepper, who starred as Theodore "T-Bag" Bagwell in Prison Break.
