Characters / Arrowverse: Leonard Snart

Go To

Leonard "Lenny" Snart
"Make the plan, execute the plan, expect the plan to go off the rails... throw away the plan."

Species: Human

Known Aliases: Captain Cold, Leo (childhood nickname)

Affiliations: The Rogues, The Legends, The Legion of Doom

Played By: Wentworth Miller, Trestyn Zradicka (young)

Appearances: The Flash | Legends of Tomorrow

A world-class thief who gets a hold of a high powered, experimental cold gun, becoming one of Central City’s supervillains. Together with his long-time friend Mick Rory and sister Lisa, they form the Rogues, who quickly become persistent thorns in the Flash's side, always managing to slip away at the last minute.

However all of that changed when Snart's father Lewis planted a nanobomb in Lisa's head to blackmail his son into committing heists for him, forcing the Snart siblings to swallow their pride and ask Team Flash for help. From then on Snart was indebted to Barry, which meant that the Rogues were no longer the terror they once were.

After some time, he and Mick were "recruited" to join the Legends. Originally the two joined soley for the chance to rob and kill on the side, but being around such noble companions forced the two to mature (though Mick still kept his rough edge) into unlikely heroes — Snart would sacrifice himself to save his team from the Time Masters.

A year after his death, Eobard Thawne's Legion of Doom recruited a past version of Snart to steal the Spear of Destiny for them, back when he was Central City's public enemy number one. But the Legends soon set things right and with a quick memory wipe, Snart was put back in time on his path to be a hero.

  • Abusive Parents: His father was a bad cop who took his anger out on him and his sister. He's still dealing with the scars left by this well into adulthood. He ended up killing him.
  • The Ace: Snart is renowned as a master thief, being able to steal anything he wants. Snart plans a heist months in advance with the utmost precision.
  • Actor Allusion: Snart alludes to his actor's past career when needing to break into a prison:
  • Adaptational Attractiveness: He's perhaps the most handsome take on any versions of the character to date.
  • Adaptational Badass: Comics Captain Cold was mainly dependent on his Cold Gun, but this version was a formidable criminal long before he acquired his trademark weapon and is a proficient hand-to-hand combatant who is more than capable with just his fists.
  • Adaptational Dumbass: Played with. Comics Captain Cold invented the Cold Gun himself, with enough scientific and technological knowledge to be the only cold based villain to master "absolute zero". This Captain Cold didn't even finish high school, and instead Cisco was the one who invented it before it fell into Snart's hands. Later subverted with the fact that even though Snart didn't invent it, he has enough knowledge to memorize its internal workings, repair it without difficulty, and even make modifications to it. And that's not even getting into Snart's tactical smarts which are second to none.
  • Adaptational Heroism: Played with. The first season of ''Legends of Tomorrow is the first known Story Arc where (the main) Captain Cold is portrayed as one of the main characters, but is a Token Evil Teammate. In contrast to his Flash Appearances, some of his ignoble characterization has been cut out.
  • Adaptational Villainy:
    • Captain Cold of the comics is a very strict Anti-Villain, who detests the idea of killing people unless he has to, especially innocents, would actively work to avoid civilian casualties, and was a Friendly Enemy with Barry. In the show, he's far more willing to endanger innocents (though, while he does mention not liking the idea of killing police officers, he specifies it's due to Pragmatic Villainy, not morals), even outright killing a man in cold blood (pun intended) to distract the Flash, and repeatedly kills other criminals he does deal with to avoid them spilling any information about him. He still seems to respect the Flash, but not to the same extent. As the leader of the Rogues, in the comics he's more interested in petty theft (and even calls out those who harm women and children or at least try to); here, his main goal is to defeat the Flash. He starts to gravitate more towards his comic book version in "Rogue Time", where he agrees to keep Barry's identity a secret — even if he does want to stay free in return — and, when the Flash hurts his pride by saying he wouldn't need to kill anyone if he was as good at his job as he thinks he is, Cold takes up the challenge, for a while.
    • Also during his time as part of the Legion of Doom, Snart was removed from the timeline before his Character Development kicked in, so he never had the chance to reform himself into the good man seen in later episodes of The Flash/Legends.
  • Affably Evil: For a Card-Carrying Villain, Snart isn't all bad. He can be quite civil with Barry when he gets a visit at his favorite bar, and as Sara finds out he can be pretty good company.
  • Affectionate Nickname: Cold is sometimes called "Lenny" by Lisa.
  • Alliterative Family: With his younger sister, Lisa. Their father is named Lewis.
  • Alliterative Name: As Captain Cold.
  • Affectionate Pickpocket: As a Running Gag after he does something suave with a woman, he will have also stolen her wallet.
  • Ambiguous Situation: It's never confirmed whether the Snart that Mick sees in season 2 is some kind of ghost or a hallucination.
  • And Starring: His appearances on The Flash (2014) is credited with "Special Guest Star" citation. Played more straight upon his Transplant to Legends of Tomorrow, although he returns to the "Special Guest Star" citation in his appearances on Legends Season 2.
  • Anti-Hero: A shameless crook whose morals aren't exactly sterling, but eventually, Snart becomes, more or less, solidly one of the good guys.
  • Arch-Enemy:
    • For Barry, second to the Reverse-Flash. Thawne actually goes on to call him Barry's "nemesis". The animosity between them only escalated after the events of "Rogue Air", only to revert back after the events of "Family of Rogues" to being more like friendly enemies.
    • Legion Snart also became one for his supposed friend Mick of all people, especially after he killed Amaya.
  • An Arm and a Leg: When Chronos has hims cuffed up in his ship, Snart uses his cold gun to freeze his hand and then shatters it in order to free himself. Rip later uses futuristic tech aboard the Waverider to regenerate his hand.
  • The Atoner: He let himself be taken to jail after killing his father, and then got a talk from Barry that he didn't need to be defined by his past and could still turn his life around if he really wanted to, which ultimately convinced him to join the Legends.
  • Awesomeness by Analysis: It's mentioned he studies potential targets for months before making his move, and describes police deployment and response time with extreme precision when the Flash foils the robbery in "Going Rogue".
  • Badass Boast: He loves speaking highly of himself, but one his best (and silliest) lines is used to counter Vandal Savage's own boast.
    Vandal Savage: Who are you to stand up to me, Vandal Savage, destroyer of empires?!
    Snart: Leonard Snart, robber of ATMs!
  • Back from the Dead: Twice, but neither truly stuck. Both times, he was taken from a time before his death and sent to the present day by a speedster but would later return back to the original point in time in which he was taken from. A 2014 Snart was recruited up by Eobard Thawne to help the Legion of Doom retrieve and build the Spear of Destiny but after the Legion's defeat he was sent back to 2014 and had his memories wiped to set his sacrifice in motion. Not long after, a 2016 Snart was picked up by Barry from 1892 Siberia to help steal a Dominator power source but after acquiring it was returned back to 1892.
  • Badass Normal: He's not a meta-human. He's just a criminal who got his hands on an extremely powerful weapon that made him dangerous. And even without it he shows his most dangerous weapon is his brain. He's also the first villain to score a clear victory over Barry. He's so skilled that in "Family of Rogues", after finally arresting him, Joe and Barry agree that it's for the best that they put him into the new metahuman wing of Iron Heights Prison, even though he's not superpowered.
  • The Bad Guy Wins: Mostly during The Flash Season One.
    • The outcome of his first episode. He gets everything he wants, defeats the Flash, leaves him alive out of his own volition and walks away scott-free.
    • Kind of wins again when he returns in "Revenge of the Rogues". While he wasn't able to get rid of the Flash, he accomplishes his other goal to at least expose the Flash to the public and still escapes prison at the end, as he prepared a Prison (Transport) Break in case he gets arrested.
    • And again in "Rogue Time", he finds out Barry's secret identity and forces him into a Cooperation Gambit, escaping arrest once more, plus recovering his and Rory's weapons, and getting a new one for his sister.
    • After a hat-trick of victories against the Flash, Snart scores another magnificent victory in "Rogue Air". Not only did he force the Flash to erase his criminal records, he's also responsible for sabotaging Team Flash's plan to send off the metahuman prisoners to Lian Yu Island. After freeing the prisoners, he recruits the majority of them to his Rogues Gallery. At this rate, Barry's ego should be used to getting trampled over by Captain Cold.
    • His winning streak is finally broken in "Family of Rogues"; though he successfully leads his abusive father Lewis on until Team Flash can free Lisa, he surrenders to Barry immediately after killing Lewis, having decided to stop running away. He's later broken out by the Weather Wizard, but refuses to help him and even warns Barry of his plans before departing, setting off his arc on Legends.
    • In "Fellowship of the Spear", he convinces Mick to betray the Legends to join him in the Legion along with the Spear of Destiny. Then in "Doomworld", he gave the winning score for the Legion by killing Amaya while she's using the Spear of Destiny.
  • Bash Brothers: With Mick Rory.
  • Because I'm Good At It: Uses this as a justification on why he's a criminal.
  • Because You Were Nice to Me: He denies it but Snart is clearly benevolent to Barry because of the latter's continually reaching out towards him.
  • Big Bad Duumvirate: Joins the Legion of Doom in the tail end of Legends Season Two.
  • Big Bad Ensemble: He was a recurring thorn in Barry's side in Season One, while having to deal with Reverse-Flash at the same time. Played even more straight in the second season of Legends of Tomorrow where he joins the Legion of Doom, a four-man supervillain team.
  • Big Brother Instinct: One of Cold's most redeeming features is how loving and protective of Lisa he is. He would even work with his father, the person he hates most in the world, to keep her safe.
  • Blood Knight:
    • In "Rogue Time", he states outright that his only motivation is the thrill of breaking the law, and knowing how good he is at it.
    • In "Doomworld", his ideal future is to own half of Central City including all the banks, so he can break into them and escape scott free with the cops letting him walk free without question.
  • Blue Means Cold: He wears a blue parka and his weapon is a Freeze Ray.
  • Book Dumb: As Felicity is quick to point out, he never finished high school, but what he may lack in academic learning, he makes up by intelligence and careful observation.
  • Brains and Brawn: Brains to Heat Wave's Brawn.
  • Breakout Character: He would steal the scene whenever he appeared on The Flash, and quickly became a fan-favorite. Most agree he was also the main selling point for Season One of Legends of Tomorrow. It really goes to show how popular he is when he kept getting brought back post-mortem in some capacity.
  • Break the Haughty: His dad coerces to pull heists with him by threatening Lisa, which forces him to change his outlook on things.
  • Bromantic Foil: His methods in approaching women are different from Ray's, but far more successful.
  • Card-Carrying Villain: One of the few in modern television. In particular, he's a rare live action Card-Carrying Supervillain. He's the first of Barry's rogues to really embrace the villain nickname given to him by Cisco, and most of his subsequent appearances have him diving into supervillain tropes headfirst and trying his damnedest to play the role to the hilt (such as making his feud with the Flash public, recruiting metahumans and forgoing the payoff for the thrill of facing the Flash) because he enjoys it far more than being a regular criminal, which initially confuses some of the more practical minded crooks he works with (at least before he converts them).
    Cold: Here's the thing: I'm a criminal and a liar, and I hurt people and I rob them.
  • Catchphrase:
    • He has a tendency to say "if you're out, you're out" before attacking one of his mooks who decided to quit on him.
    • “Always pleased to meet a fan” when he meets someone who states they know who he is.
  • Celebrity Paradox:
  • Character Development: While he starts out as largely uninterested in stopping Savage, after Carter dies and he witnesses the horrors that Savage plans to unleash, Snart forms a somewhat frosty but nonetheless sincere loyalty to the team, and reaches the point where he refuses to abandon the mission to stop Savage. Later he genuinely comes to the rest of the team's views. By the end of the season, he also comes to genuinely care about the rest of the team to the point that he choices to sacrifice himself in Mick's place, something the old Snart would never do. This is lampshaded before he dies by Sara, who notes that Snart isn't the same "cold-hearted bastard" he was at the beginning of the show.
  • Characterization Marches On: In Season One of The Flash, he was a Bad Boss who killed several of his men for trying to back out of a job. By the time he joins the Legends, Snart establishes himself as a firm believer in True Companions, commenting that he would never abandon his crew and being motivated by revenge for a fallen teammate. (There's still some level of consistency, given that the accomplices he killed abandoned him first by trying to walk out and potentially becoming liabilities. Reconnecting with Mick and Lisa and being reached out to by Barry may have also had a hand in releasing his team player side.)
  • The Charmer: He is able to charm a Pentagon soldier and Vostok.
  • Civvie Spandex: He does don the blue parka and goggles while he's masquerading as a supervillain, but quite often he just wears casual clothes too.
  • Clock King: He carefully studies police response times down to the second.
  • Cold Ham: Puns aside, Snart rarely, if ever, raises his voice, but his dialogue positively drips with ham.
    Snart: The Scarlet Speedster. Any preference on how you'd like to die? The flame or the frost?
    Barry: ...
    Snart: Not in the mood for chit chat. Gotcha. Ready when you are.
  • Color-Coded for Your Convenience: During the Legends episode where Sara and Kendra have to collect baby Leonard from the hospital nursery in order to protect him, all the other infants are wrapped in light colored blankets. Baby Leonard, on the other hand, is wrapped in a black blanket. Even his sleeping cap is black. May also be a case of Foreshadowing. It doesn't, however, stop Kendra and Sara from immediately swooning and cooing over how cute baby Leonard is.
  • Comic-Book Movies Don't Use Codenames: While he does like the nickname "Captain Cold", nobody aside from Team Flash seems to refer to him by that name. Most just call him "Snart", with the exception of Sara and Lisa who go by his first name.
  • Commuting on a Bus: Despite being Killed Off for Real in "Destiny", he continues making numerous postmortem appearances on The Flash or Legends of Tomorrow either through flashbacks, hallucinations, projections, or time travel.
  • Conflicting Loyalty: It doesn't start that way, but Snart ends up having to choose between his newfound loyalty to the team and his lifelong friendship with Mick. After Mick's betrayal in "Marooned", Snart chooses the team.
  • Contagious Heroism: Snart's gradual interactions with Barry and being helped out by the hero eventually help him go through a Heel–Face Turn. By the end of Season One of Legends, he proves willing to perform a Heroic Sacrifice to save his team.
  • The Corrupter: Snart is this for Mick throughout Legends Season Two. The Snart hallucination keeps chiding Mick for turning soft, while the real Snart manages to convince him to leave The Legends side and join The Legion instead pointing out that the Legends will never respect him or see him as anything more then a thug.
  • Crazy-Prepared: Snart has a plan for everything. When he and Rory are being transported to Iron Heights, he's calm and collected. Why? Because in case that happened he already arranged to have his sister break them out as part of a contingency plan.
  • Create Your Own Villain: By refusing to kill Mick, Snart inadvertently creates Chronos.
  • Cuteness Proximity: When he was a baby he caused this reaction in both Kendra and Sara.

  • Dead Alternate Counterpart: For his Earth-X counterpart, Citizen Cold.
  • Deadpan Snarker: Snart can't resist taking the piss out of anyone and everyone he comes across, especially if that person happens to be Barry or Ray. He becomes arguably the biggest snarker in a group already filled to the brim with them.
    • The Flash Season One gave us this gem:
      Joe: Your partner's a real hot-head.
      Snart: That's funny.
      Joe: You know what's hilarious, Snart? We got you.
      Snart: Congratulations.
    • Then in Legends of Tomorrow.
      Ray: Maybe I am dead right now... Hello? Can anybody hear me?
      Snart: No.
  • Debt Detester: He may not want to admit it, but he doesn't go after the Flash anymore since he saved Lisa's life. He is however perfectly fine with other villains going after the Scarlet Speedster, and the most he'll do for the Flash is let him know that trouble's coming.
  • Defiant to the End: His last words even evokes this.
    Snart: There are no strings on me!
  • Desperately Looking for a Purpose in Life: In his first appearance, he was largely bored. He committed crimes for the money, but planned everything so perfectly that there was barely ever even a chance of him losing. Fighting Barry quickly became his passion, and he took on the Large Ham mantle of "Captain Cold" the second it was offered.
  • Determinator:
    • In his introductory episode, Joe notes that while Snart has faced setbacks in the past, once he sets his sights on a prize, he never gives up until he gets it. In the same episode, we see what happens to members of his crew who don't share his persistence.
    • He freezes his own hand solid, then shatters it, frees himself from Chronos' handcuffs, and makes his way through Nanda Parbat with barely any sign of pain (apart from when he shattered the hand). And this was before he even knew that the Ship could recreate his hand.
  • Didn't See That Coming: Didn't think that the Flash would let himself get hit by both guns to force the streams to cross. But he was aware of the possibility of losing, and had a backup plan.
  • Dissonant Serenity: The contrast between him and Stein is made perfectly clear when Snart kills a gunslinger who was about to shoot Stein.
    Martin: [shaking and terrified] You just killed that man!
    Leonard: [smiling] You're welcome.
  • Doomed by Canon: Since his future self dies in a Heroic Sacrifice in Season One of "Legends", Legion Snart was put back into the timeline and has his memories wiped, so that he can be back on the path for redemption and eventually dying.
  • 11th-Hour Ranger: He doesn't join the Legion until the last three episodes of Season Two.
  • Even Evil Has Loved Ones: As Barry points out, "You would do anything to protect your family, just like me."
  • Even Evil Has Standards:
    • He may be a thief, but he no longer kills unless it's in self-defense, and he isn't pleased with some of Savage's more brutal acts. When he sees the crime-ridden Star City of 2046, he hates it as it's just mindless thuggery, no skill and also the lack of fun in being a crook in a world with no law.
    • Ruthless as he is, he's appalled by his dad's sadistic streak and doesn't like the Trickster's antics either.
  • Evil Costume Switch: Legion Snart wears a dark blue coat, in contrast to his future reformed self who wore a blue parka.
  • Evil is Petty: In "Rogue Air," Snart sticks the bill for his own meal on Barry and kills Deathbolt just because he owed him money.
  • Evil Has a Bad Sense of Humor: See the Visual Pun he made as he killed Amaya.
  • "Facing the Bullets" One-Liner: Gives one during his Heroic Sacrifice where he prepares to blow up the Time Master's base and himself along with it.
    Snart: "There are no strings on me."
  • Faux Affably Evil: Before his Character Development. Perfectly shown with his past self, who gets picked from the time stream by the Legion of Doom.
  • Fire/Ice Duo: With Mick Rory. Much like the comics, the two of them are once again criminal buddies, brandishing their Cold Gun and Heat Gun respectively. Their personalities are complete opposites, with Snart being The Stoic and snarky, while Rory is Hot-Blooded and reckless. To make it even better, if the beams of their guns cross they will end up cancelling each other out. This carries on into Legends of Tomorrow where both serve as the Token Evil Teammates.
  • Foreshadowing: Mick's been seeing hallucinations of him all season long.
  • Forgotten Fallen Friend: Defied. When Barry gathers everyone to fight the Dominators, he notes Snart's absence among the Legends and pulls Ray Palmer aside to ask what happened. The two share a brief, but solemn acknowledgement of his Heroic Sacrifice.
  • Forgotten First Meeting: Technically, he first met the Legends in Season 2 as the Legion picked him up from the timeline two years before Rip recruited him in 2016. However, Mick then wipes his memory of ever meeting the Legion nor the Legends to set him back to his path to become a Legend. This also means that the time Rip recruited him to the Legends was the second time he met them, he just didn’t remember about his time with the Legion due to a memory wipe.
  • For the Evulz: Snart is primary a criminal for fun. He does it because he's good at it and not out of necessity. This is highlighted in Doomworld wherein Snart's ideal reality is one that allows him to rob banks without being arrested by the police, since he owns the banks he breaks into.
  • Freeze Ray: His Cold Gun, his weapon which is said to be a miniature cold generator that shoots "flames" that achieve absolute zero.
  • Freudian Excuse: His dad was an Abusive Parent who taught him and his sister how to be crooks.
  • Friendly Enemy: He has this to a degree with The Flash and his team at least from his own side as shown in "Rogue Air" where he chats amiably with them, seems to respect them and is willing to protect Barry from Deathbolt. However he's still a (self admitted) liar and criminal and he's not afraid to manipulate and use the team to get what he wants.
  • Friend to All Children: He's quite friendly to most children (a young Per Degaton being the main exception).
  • From Nobody to Nightmare: From ordinary street thug to Central City's first true supervillain in a matter of days. Justified in that he already had all the makings of a supervillain aside from the proper gear and protagonist, and as they say, luck is preparation locking heads with opportunity.
  • Future Me Scares Me: Legion Snart was disgusted that he'd eventually become a hero that sacrifices himself for others and hates the thought of becoming "soft". This leads him to join the Legion to avert this future.
  • Gadgeteer Genius: While not as smart as Cisco — he's not able to create a new cold gun by himself — he is smart enough to disassemble, then reassemble it, and is familiar enough with its mechanics to know when Cisco tries to sabotage the second one Cold is forcing him to make.
  • Glass Cannon: He's not a metahuman, so he's just as vulnerable as a typical human being. However, his extremely high offensive powers thanks to his Cold Gun more than make up for this.
  • Goggles Do Something Unusual: Not really unusual; they protect his eyes from the glare that comes from the Cold Gun. Also counts as Stylish Protection Gear.
  • Go Mad from the Revelation: Legion Snart learns that his future self become a hero and performs a Heroic Sacrifice has made him more aggressive than he normally is.
  • Graceful Loser: Takes his loss to Flash well. Probably because he had a backup plan.
  • The Gunslinger: "The Magnificent Eight" shows that he's a talented quick draw and gunslinger, even able to disarm a bandit from miles with a rifle.

  • Harmful to Minors: His father took his son on his crime runs and had Leonard do everything he was too large to do, which is how Leonard learned to be as great a criminal as he is currently.
  • Heel–Face Turn: He slowly makes one over the course of the first season and a half of The Flash and first season of Legends. He goes from Card-Carrying Villain and Bad Boss who thinks Virtue Is Weakness to the Friendly Enemy of his city's hero to a Token Evil Teammate on a ragtag time squad…to a True Companion who's willing to make a Heroic Sacrifice to give the rest of the team their best chance at fulfilling their ultimate mission of stopping Savage.
  • Heel–Face Revolving Door: Nearing the end of Legends of Tomorrow Season One, he has mostly reformed into a Lovable Rogue. However he's still not above being a jerk and sticking his Cold Gun on Sara when he doesn't get his way. Sara later calls him out on it and he does admit he was in the wrong.
  • Heroic Sacrifice: Let the irony sink in. Cold sacrifices his life to destroy the Occulus and save his friends.
  • Hero Killer: Legion Snart kills Amaya in cold blood, literally, then shatters her frozen body to pieces.
  • Heterosexual Life-Partners: He and Mick have been friends for a long time. Although as shown in Doomworld, Snart before his Character Development tended to look down on Mick and treated him more like an attack dog at times than a full-fledged partner.
  • Hidden Depths:
    • "Family of Rogues'' shows he's more complex than being a Card-Carrying Villain, he genuinely loves Lisa and he's disgusted by his dad's cruelty.
    • Also, anyone who gets picked up and carried by a speedster is usually extremely disoriented and dizzy once they're put down (Eiling was unable to stand and mostly incoherent after the Reverse-Flash ran him across the city). Snart, on the other hand, just needs a split-second to get his balance after Barry grabs and runs with him, and he's grinning like a kid who just got off the roller coaster.
  • Hypocrite: He mocks Mick by claiming he lets the Legends treat him like an attack dog, but treats him exactly that way in "Doomworld", which Mick ultimately calls him out on.
  • An Ice Person: He isn't a metahuman like other villains so far, instead he uses a "cold gun" that can slow atoms down to absolute zero. Even before that, he used liquid nitrogen to freeze and break open an armored truck. He also offers a boy some cool mint gum.
  • An Ice Suit: Once he settles into his supervillain role, he dons a dark blue parka.
  • Iconic Outfit: He dons a blue parka to go with his Cold Gun and goggles, once he takes up the mantle of a supervillain.
  • Iconic Sequel Character: While he's introduced early in The Flash (2014) Season One, he does not appear in the Arrowverse until its third year.
  • I Gave My Word: Claims this trait, though living up to it is another matter, as is whether what he promises being a case of Exact Words or not. To his credit, he does promise to keep Barry's identity as The Flash a secret, and remains true to it, not even telling his sister.
  • I Lied: In "Rogue Air", he agrees to help Barry transport the metahumans to a secure location in exchange for Barry removing everything ARGUS has on him. However, Snart ends up freeing the metahumans so they'd owe him one. When Barry confronts him over it, Snart reminds him that he's a criminal and a thief, so it's really Barry's fault for trusting him in the first place.
  • Impossible Thief: Snart has an unparalleled reputation at being a master thief. In "Infantino Street" he was able to crack the Montgomery 3000 lock (said to cost 10 million dollars and virtually unbreakable) in 37 seconds, before adding he was "out of practice." The Legion of Doom hired him specifically for his skills in thievery, while Barry recruits him in Season 3 to steal a power source from ARGUS.
  • Indy Ploy: When Snart debuted, he had grown accustomed to meticulously thought-out plans that always went off without a hitch, leaving him almost bored with crime. Then the Flash showed up. Come the ARGUS heist and:
    Snart: Doesn't matter. There are only 4 rules you need to remember. Make the plan, execute the plan, expect the plan to go off the rails... throw away the plan.
  • In the Hood: He wears a hooded dark blue parka.
  • Irony: The man who claimed "hero ain't on my resume" ultimately dies a hero. Ray even remarks that the last thing Snart would have wanted said about him is that he was a hero.
  • It's Personal: His reason for going after Savage. He may not have known Carter from Adam (his words), but Carter was part of his crew all the same, so killing him put Savage on Cold's hit list.
  • It's What I Do: In "Rogue Air" when Barry recruits Snart but then gets mad at his betrayal, Snart chides that he's a criminal and that hurting people was what he did, so the one Barry should really have been mad at was himself for trusting Snart to begin with.
  • Jerk with a Heart of Gold: He's cold, distant, and kind of a dick, but Snart is far from heartless, even developing a genuine friendship with some of his teammates.
  • Jerkass Has a Point: While he is a crook and kind of a jerk, Snart is very smart and perceptive. For instance, his suggestion of killing Per Degaton as a child would arguably have worked out for the best had the team followed through on it.
  • Jumped at the Call: Just check out the way his face lights up when he first hears his supervillain name. When he comes back in "Revenge of the Rogues", it's obvious that he revels in the opportunity to be a bona fide super villain.
  • Karma Houdini Warranty: In Season One of "The Flash", he always managed to get away much to Team Flash's constant frustration. In Season Two, he finally gets karma in the form of his abusive dad Lewis, who implants a bomb in Lisa's neck to blackmail Leonard into working with him; on the flipside this was the nudge towards turning him into a hero.
  • Kick the Dog: The Doomworld, pre Heel–Face Turn version of him is practically a professional dog-kicker, attempting to kill Nate after Mick tells him not to, and killing Amaya when she's about to use the spear and then mocking Mick by commenting that he knows that Mick loved her to pieces. In the final battle, after Doomworld Mick proclaims his loyalty to the Legends, Snart responds by shooting him in the back with the cold gun and killing him.
  • Killed Off for Real: Despite coming back two times via time travel and being temporarily replaced by his Earth-X counterpart, the real Snart was never revived, and with Wentworth Miller leaving the Arrowverse, the changes of him being brought back from the dead are pretty much zero now.
  • Kill It with Ice: His Cold Gun freezes anything, and yes it does kill.
  • The Lancer: He, The Atom, and White Canary share this role, as they all stepped in leadership role on a few occasions Rip is not around or in some kind of funk.
  • Large Ham: While Miller plays Snart as a unflappable strategist who has a plan for everything and stays calm and collected all the time, there are occasions when Cold really hams it up (and Miller clearly enjoys every minute of it). A good example is in the Season Two opener of The Flash when Barry fights him and Mick (admittedly, it's just a daydream):
    Mick: He's coming back, Cold!
    Snart: YES! TO DIE!
  • Laser-Guided Amnesia: The Legends wipe his memory and then drop him back off in Central City like he never left.
  • Leaning on the Fourth Wall:
    • When Rip is explaining the schematics of a prison and asks if everyone understood, Snart says "This isn't my first prison break."
    • In "Infantino Street", Snart makes a remark that references CW's limited CGI budget in showing King Shark.
      Snart: Reminds me of Jaws. They didn't show the shark because they couldn't afford to make it look good.
  • Leitmotif: Has a very distinctive militaristic marching theme music.
  • Literally Shattered Lives:
    • When Mick cuffs him to the ship, Snart frees himself by using his Cold Gun to freeze his own hand and then shatter it. Yes, it's painful.
    • Legion Snart does this to Amaya, icing her up and then tapping her frozen body so she shatters to pieces.
  • Lovable Rogue: As a member of the Legends, he's less of a psychotic killer and more of a ruffian who likes to bend the rules.

  • Man of Kryptonite: His Freeze Ray was specifically built by Cisco to counter the Flash in case he ever went rogue. It was stolen by a janitor working at S.T.A.R labs who tried to sell it to Leonard who promptly used it on him. It turns Leonard from a skilled, yet petty thief to a dangerous superpowered threat. That said, Snart doesn't consider it to be the Flash's real weakness, but rather his need to help others.
  • Manipulative Bastard: Clearly enjoys manipulating events to benefit himself.
  • Movie Superheroes Wear Black: While he stills wears a blue parka, it's now a dark navy color rather than the bright shade seen in the comics.
  • My Future Self and Me: Meets his child self in 1975 and gives him a Rousing Speech.
  • My Sister Is Off-Limits: Discussed, he's more shocked that his sister kissed Cisco as part of her Honey Trap, but he's not actually mad about it.
  • Nerves of Steel: Even though its only the fourth episode, by the time Snart's on the scene, people are aware of the Streak, and after his first robbery is foiled, his crew decides Central City is too hot for them. Snart, on the other hand, never shows fear, neither of Barry, the police, or even when his own crew draw down on him. He just makes a plan, and is able to hand the Flash a solid defeat.
  • Never Found the Body: His corpse was never recovered after he sacrificed himself. However, it is widely assumed he is dead, especially given he is not present at the next time the Vanishing Point is featured during Season Two when it is used by the Legion of Doom.
  • Noble Demon: Despite being a criminal, he has a code of honor, never to leave behind one of his own. He gets all the more honorable the longer he stays with the Legends to the point where his first loyalty lies with the team and he's even willing to sacrifice himself for them.
  • Not in This for Your Revolution: He and Heat Wave stay on the team just for the opportunity to kill people and steal stuff. And later to avenge Carter's death. Eventually, he does come around to the rest of the team's viewpoint, even when Rory hadn't.
  • Not So Stoic: He has the happiest smirk on his face when he hears Cisco dub him "Captain Cold". Also when Barry call his team the Rogues.
  • "Oh, Crap!" Fakeout: Mick claimed he was obsessed with the Flash to the point of forgoing his usual planning and pragmatism. Except not, it's all part of the plan.
  • Odd Friendship:
    • He and Mick hit it off with Sara pretty quick.
    • After a rough start, he and Ray develop a grudging respect for each other's skills.
  • One-Steve Limit: Was annoyed when Rip Hunter addresses himself as The Captain of the ship because he also goes by Captain Cold. When he meets his child self, the kid addresses himself as "Leo".
  • Only in It for the Money: Literally. He and Mick only joined the team because of all the treasures they can steal from their Time Travel adventures.

  • Paradox Person: Legion's Snart is this, as he was pulled from the time stream before his death just like Darhk. This Snart is from Barry's early days as the Flash back when he was still a wanted, unapologetic criminal. Again just like Darhk, it becomes a moot point when he gets dropped back in 2014 and had his memory modified like nothing changed.
  • Personality Powers: Well, it's a gun rather than his own power, but he's still a stoic, calm professional that gets a cold gun. Justified since he specifically chooses the Cold Gun, even rejecting the Heat Gun he's offered before. Even before that, however, he used a liquid nitrogen projector in heists.
  • Pet the Dog:
    • Offers a kid a stick of gum and banters with him while casing a museum.
    • Before he gives Cisco the ultimatum of revealing the Flash's identity or his brother will be killed, Snart tells Cisco that he genuinely admires and respects him for all the hard work he's done in working to escape his difficult childhood situation and make something out of himself. Snart does this without any hint of irony or sarcasm and it's plain that he is completely sincere.
    • After getting what he wants, he releases Cisco and his brother from the Rogues' captivity instead of the usual take.
    • He goes out of his way to warn Barry of Mardon and James' plans.
  • The Plan: He begins forming one, once he gains his freeze ray and after his first battle with the Flash.
  • Pragmatic Villainy: Snart is willing to steal, kill, and endanger the lives of civilians to achieve his goals. However, he doesn't act without reason, and he chooses not to shoot cops or murder bystanders if he can help it, because it's not worth the time or the attention from the cops. In fact he backs out of a Villain Team-Up with Weather Wizard and the Trickster to kill the Flash, simply because there's no profit to it.
  • Promotion to Parent: Given the aforementioned Abusive Parents, it's implied that Leonard was Lisa's caregiver growing up. Lisa confirms it in "Family of Rogues", claiming that having Lenny as an influence rather than their father alone is the reason the siblings are not worse than bank robbers packing powerful firearms.
  • Pungeon Master: Passively pummels people with a plethora of ice puns.
  • Punny Name: Given his immensely sarcastic nature, his name might as well be Leonard Snark.
  • Quick Draw: As shown in Wild West episode of Legends, he's very fast on the draw.
  • Redemption Equals Death: After starting out as a criminal and then starting the first season of Legends of Tomorrow as a Token Evil Teammate, he gradually changed his ways culminating in him sacrificing himself for The Team.
  • Red Oni, Blue Oni: He and Mick as their elements and Color Motif suggest. He's the more levelheaded, methodical, and calculating of the two (Blue).
  • Resurrected for a Job: The Legion pulled him from the time stream specifically to steal The Spear of Destiny for them.
  • Secret-Keeper: Finds out Barry's identity in "Rogue Time"; agrees to keep it secret as part of a Cooperation Gambit; Barry doesn't get him arrested, or locked away in secrecy, as long as Len keeps the secret and adopts a Thou Shall Not Kill policy.
  • Self-Made Orphan: Leonard kills his father with his cold gun in "Family of Rogues". This took place the second after Team Flash extracts a bomb Lewis put inside Lisa's head to force Leonard into his most unwanted partnership. This is a notable departure from the comics where he couldn't bring himself to kill his he had Heatwave do it for him.
  • Shadow Archetype: Snart and Barry were both raised by cops, at one point saw their fathers going to prison, developed Awesomeness by Analysis and eventually got powers from STAR Labs—either permanently or through gadgets—but, in terms of personality, simply became powered-up versions of who they already were.
    Barry: Snart's dad is in prison, too? We should start a club.
  • Siblings in Crime: Is this with Lisa.
  • Sinister Shades: They're goggles, but they're clearly meant to invoke this.
  • The Smart Guy: He's the most street smart of Rip Hunter's team.
  • Sticky Fingers: He cannot help but steal anything of value that presents itself to him.
    • When tasked with stealing a mystical relic able to kill Savage, Snart proceeds to swipe every treasure of value along with it.
    Snart: Raymond, you don't break into a candy store and steal one gumball.
  • The Stoic: He almost never raises his voice and maintains a deadpan expression.

  • Tall, Dark, and Handsome: He stands 6'1 and is definitely not a bad looking man.
  • Tall, Dark, and Snarky: He stands 6'1 and is one of the snarkiest characters in the franchise.
  • Taught by Television: In "Infantimo Street", he displays a surprisingly lot of knowledge about shark biology. He reveals he learned this from watching Shark Week.
  • Thou Shalt Not Kill: Originally, his view on killing fluctuates based on whether it helps or hurts in getting a job done, but after he kidnaps Cisco, Barry challenges his pride by saying if he were as good as he claims he could do the whole supervillain thing without killing anyone, which Cold agrees to. Later, seeing how casually his dad kills people makes it a genuine belief instead of a rule of Pragmatic Villainy.
  • Token Evil Teammate: His role in the Legends, along with Heat Wave. He starts to grow out of it.
    Cold: I can't imagine any kind of future where I'm a hero.
  • Tom the Dark Lord: Of the most notorious criminals in Central City and the most dangerous non-meta The Flash has taken on... is named Leonard.
  • Took a Level in Kindness: On Legends, Snart is rather more personable than he was on The Flash. He's still a criminal, and hardly the kindliest of individuals, but he's at least advanced from Faux Affably Evil to genuinely Affably Evil.
  • Touché: Barry plays to his pride at one point during their "negotiation" in 1x16, to get him to conduct his heists without murdering any innocent people going forward.
    Flash: If you're as good as you say you are, you don't have to kill anyone to get what you want.
    Cold: ...That's true.
  • Toxic Friend Influence: He convinces Mick to leave the Legends and join the Legion.
  • Trailers Always Spoil: His appearance would've come as big shock had it not been advertised in the trade papers for months in advance, including before Season 2 of Legends of Tomorrow even aired.
  • Transplant: He was a major recurring antagonist in The Flash (2014).
  • Troll: In "Fail-Safe" when Rip is having trouble taking on one big Bratva member, he offers to let Snart have the fight, to which Snart feigns generosity by giving the whole fight to Rip while watching him get clobbered.
    Snart: He's all yours.
  • True Companions: While he might not like specific people in the group he's in, once you roll with him, anyone who messes his crew will pay the price. After Carter dies, Snart throws his lot in with the team to get payback against Savage.
  • Tyke-Bomb: It is revealed that his father Lewis trained him at a young age to be a top-notch criminal.
  • Unfortunate Names: "Leonard Snart" isn't going to be winning him any coolest names awards any time soon. Both Barry and Joe think it's lame.
  • Victory Is Boring: According to Miller, he's been pulling off flawless thefts with no consequences for so long it's grown boring, and he welcomes the challenge that the Flash presents.
  • Villainous Friendship: With Mick Rory.
  • Villain Has a Point: As he point outs the Legends really didn't put much trust in Mick and basically treated him like a glorified attack dog.
  • Villain Protagonist: He is part of the main Ensemble Cast of Legends of Tomorrow and is their proud Token Evil Teammate.
  • Villain Respect: The only member of the Legion that Eobard doesn't begrudgingly recruit; he acknowledges and respects his abilities as a master thief and happily welcomes his skills, unlike those of a guy in a pastel suit and shoes with no socks, or a jaded wash-out from a crappy apartment.
  • Virtue Is Weakness: He consider's the Flash's real weakness not to be his Freeze Ray, but the fact that he helps people. He takes advantage of this by derailing a train and forcing him to save all the passengers.
  • Visual Pun: Legion Snart freezes Amaya with his Cold Gun, then...
    Snart: I am sorry about your friend, Mick. I know you loved her to pieces.
    [Snart taps Amaya's frozen body and shatters her].
  • Vocal Evolution: In Snart's first apperance he spoke with Wentworth Miller's regular tone of voice, before gradually evolving into the Cold Ham voice heard from his subsequent appearances; including from his Earth-X doppelganger.
  • Walking Spoiler: Thawne, Darhk, and Merlyn being members of the Legion was well advertised in press releases and promotional photographs, while Snart's involvement had been very hush hush.
  • White Hair, Black Heart: His hair has a distinct silver shade. It's especially prominent for Legion Snart who is a much more ruthless criminal than his future self.
  • With Friends Like These...: He and Mick have already shown willingness to conduct heists and follow personal vendettas at the most inopportune times for the team. He and Mick are also this, as while they seem to be friends, they're perfectly willing to point guns at each other if one of them screws up a job.
  • Worth It: His attitude towards killing his father. It's one crime he's perfectly willing to go to jail for.
  • Worthy Opponent: Seems to see the Flash as this, going as far as thanking him for keeping him on his toes. He's also notably hesitant to kill him, especially after Barry helped save his sister.
  • Would Hit a Girl: Or freeze them with his Cold Gun then shatter them, as what happened to poor Amaya.
  • Would Hurt a Child: In a Shoot the Dog sense, Snart is the only one of the team who shows little hesitation with the idea of killing a young Per Degaton. That said, he never tries to, nor is he in a position to try to follow through on this.
