Leonard Snart

"Pretty pathetic, if you ask me."

- Leonard Snart's past self to the Legends

Leonard "Lenny" Snart (born June 2, 2345), nicknamed Captain Cold by Cisco Ramon (or simply Cold), was a male Human who was a world-class thief from Central City. He was also the older brother of Lisa Snart and the son of the late Lewis Snart.

In 2380 after the appearance of Barry Allen/The Flash, who started endangering his heists with his heroics, Leonard sought to eliminate him. Acquiring the cold gun he had frequent encounters with the Flash, along with his partner Mick Rory/Heat Wave. In 2381 Snart and Barry reached a truce where Barry would let Snart continue his heists, so long as he didn't kill anyone in the process and became an occasional ally of his.

In early 2389 Snart and Mick were recruited by Rip Hunter into the Legends, a time travelling team of superheroes dedicated to hunting down Vandal Savage and preventing his uprising in 2166. Being considered "supervillains" he and Mick were seen as outcasts. Though both initially joined to exploit the potentials of time travel Snart came to be genuine about the cause, and genuinely befriended the Legends. He also became close with Sara Lance/White Canary and developed a romantic interest in her. However Snart's change of heart led to a falling out between him and Mick. Following Mick's betrayal of the team, allying with time pirates to save himself, Snart was forced to maroon him in time which indirectly led to him becoming Chronos. After talking sense into Mick they continued the Legends mission together. When the Legends were in danger of being killed by the Time Masters in the Vanishing Point, after learning they were in league with Savage, Snart sacrificed himself to save his friends and destroy the Time Masters, ending their corruption. Leonard's death was avenged when the Legends finally killed Savage.

In 2390 a younger version of Leonard from 2388, prior to joining the Legends, was pulled from the timeline by Eobard Thawne/Reverse-Flash and recruited into the Legion of Doom to aid in their quest to retrieve the Spear of Destiny.

Personality
Leonard is a ruthless man who has a calm, composed and level-headed demeanor, rarely ever losing his temper or giving into emotions. Although he never finished high school, he is intelligent and patient, staking out a job for months before making his move, emphasizing timing, precision, and minimizing possible leads on him and his activities by refusing to kill unless necessary. He was also clever enough to deduce that what stopped his job at the armored car was in fact a man, and that he would need a weapon to halt Barry, choosing the Cold Gun for this very reason. Leonard has, however, begun to revel in his new-found weapon's power, and his battles with the Flash have begun to alter his perceptions of how the job works, transforming from an armed robber into a "supervillain" that would directly challenge the Flash. The change in his demeanor is astounding, as Leonard can be seen acting much more ruthless before meeting the Flash: he killed the man who supplied him the Cold Gun for the sake of convenience, and before that tried to kill Sam Scudder and Rosa Dillon for going against his orders as a crime boss.

Despite his unapologetic criminal lifestyle, Leonard sees and declares himself as a man of his word. This is demonstrated further, when he promises to release Cisco if he tells him who the Flash is. Although he does torture Dante to get this information from him, he keeps his word afterwards and lets both Cisco and his brother go. However he doesn't always keep his word when he betrays his alliance with Barry by setting the meta humans free. Leonard simply defends his actions by claiming that he is a criminal that saw an opportunity and used it for his own benefit because that's who he is.

Regardless of Leonard's ruthless nature, one of the only things he does care about is his younger sister Lisa, who he has a close relationship with her, despite her immaturity. He severely despises his father Lewis, for what he did to him and his sister; for physically abusing them as children for no apparent reason, he became disgusted when Lewis planted a bomb inside Lisa's head in order to manipulate him into helping him with one of his heists, however, after Barry told him that the bomb was removed from Lisa, without hesitation he killed his father for what he did to his sister. He is also quite prideful; Barry deduced that Snart was going along with his father's plans because Lisa was being threatened because he concluded that Snart would have tried to dig the miniature bomb out of his own head if one was planted in him. A similar case happened while Snart was handcuffed to a wall, he managed to reach his Cold Gun, and when he could not use it while he was restrained, he used his feet to fire the gun and intentionally turn his hand to ice and then proceeded to shatter it against the ground, despite the great pain of it. He still walked out without much grief over his injuries, focusing on escaping and the task of stopping the team from killing Chronos, who was actually Mick Rory.

Despite being enemies most of the time, Leonard and Barry seem to possess a mutual respect for each other; although he betrayed him, Leonard saved Barry from certain death at the hands of Jake Simmons. A few months afterwards, his liking of Barry increased to the point he felt genuine remorse after his father shot him. Barry also visited Leonard upon the latter's arrest. Leonard even refused to go along with Mark Mardon and James Jesse's plan to kill Barry and instead warned him of what they were up to before departing. Leonard deeply cares about his sister, going as far as working with a man he slightly hates (due to his more moral and honorable ways) in order to keep her safe. All of these qualities have led Barry to believe Leonard has good inside of him and that he'll eventually change his ways (although Leonard jokingly remarks that heroes don't get paid enough). Another instance is when Snart is broken out of prison, instead of going after Barry to kill him, he warns him. When Barry asks where the other two (Mark and Jesse) are, Snart says "Barry and his friends love to solve a good mystery" and goes to leave. Barry snorts at this and tells Snart that he's there because he (Barry and co) saved Lisa and Snart doesn't like owing him one and that's called honor. Snart is quiet for a brief moment before wishing Barry and Iris merry Christmas and leaves.

Leonard also possesses a code of honor when it comes to his teammates, shown when he becomes a full-fledged member of Rip Hunter's team after Carter Hall is murdered by Vandal Savage. When he deduces that Hunter wants Sara Lance to kill Martin Stein in order to prevent the devastation of the Cold War in the present time if Stein breaks and agrees to help the Soviets create their own Firestorm, Leonard is against the idea as he doesn't believe in turning on his own team members and manages to talk Sara out of shooting Stein, showing a profound understanding of her nature and drives and expertly employing reverse psychology. Proving himself not a hypocrite, Leonard also refused to kill Jax when he was mutated by Savage into a feral bird-creature, allowing his team to ultimately cure Jax. When he threatened Sara Lance at gunpoint, trying to force her to escape the Vanishing Point on the timeship while abandoning the rest of the team, she stood her ground without fear, knowing that for all his threats, Snart was no longer the cold-blood murderer, but a hero, who'd never kill his teammates. That proved to be true after Snart admitted his bluff and helped Sara with the rescue of their team members captured by the Time Masters. During the rescue they encountered Mick Rory, seemingly brainwashed into being Chronos once again. Snart refused to attack his friend, which was recognized by Rory, who turned on the Time Masers instead.

Leonard is incredibly charismatic, maintaining the image of a "lovable rogue", using his charms to get important information, obfuscate his thievery or convince people of his trustworthiness. This way, he gained the trust of Valentina Vostok and Cassandra Savage. Leonard himself was interested in Sara Lance, flirting with her on occasion, drinking and playing cards with her and even apologizing for being "a jerk". However, Sara declined his advances with a smile on her face, saying that he'd need to be a master thief to steal a kiss from her. Despite this, Sara and Leonard kissed at the Vanishing Point, when Leonard decided to sacrifice his life to destroy the Oculus device in Mick Rory's and Ray Palmer's stead.

Being prone to controlling or playing others, Leonard absolutely detests the idea of being controlled or manipulated by anyone or anything. He values his free will and the ability to make his own choices and will do anything to hold on to that freedom. This is a trait that is so dominating in his personality that he destroyed the Oculus in the Vanishing Point not just out of compassion for his teammates, but because he wanted to make sure that no one else would be manipulated by the "Time Bastards" as he referred to them.

Abilities

 * High-level intellect/Expert tactician: Leonard's most noticeable and dangerous trait is high intellect, making him a threat even to metahumans like the Flash. Very calculating and methodical in every action he takes, Leonard is infamous for analyzing and preparing for events well in advance. He is able to plan for every plausible detail several steps ahead and even when new variables come into play, he can calmly change tactics to escape unscathed. Likewise, he is highly adept in misdirections and subtle manipulations of his targets/enemies to suit his plans. Despite dropping out of high school, Leonard has repeatedly shown an advanced knowledge of various subjects, including biology and engineering, able to at least understand the nature to which they operate. Leonard is very charming (when he wants to be), able to seduce Valentina Vostok. He is also shown to be very persuasive, able to sway the immensely loyal lieutenant, Cassandra Savage, to turn on her father, Vandal Savage, and aid the resistance.
 * Eidetic memory: In his nature for preparation, Leonard has repeatedly displayed an unusually adept memory, being capable of memorizing the details of every job before mobilizing simply by analyzing the information. For more regular use, Leonard is able to memorize every last meticulous detail of the highly technologically advanced Cold Gun to personally perform regular maintenance and repairs without the need of instructions or schematics. He did this to have a better control and usage of his signature Cold Gun by learning all of its parts and inner workings after disassembling and reassembling his weapon.
 * Expert engineer: While not as skillful as Cisco Ramon or Ray Palmer, Leonard has adept skill in electrical engineering, obtaining this skill from growing up with his father, forced to regularly join and aid him in thefts. He is able to quickly understand a software setup and effectively deactivate it. Likewise, he was shown able to modify his Cold Gun for additional features.
 * Expert thief: Over the years of criminal experience, Leonard has mastered the art of thieving, from armored car heists, jewel theft and bank robbery, he displays the utmost skill.
 * Expert marksman/Firearms: While normally preferring to avoid killing when not necessary as to not sully his plans, Leonard is more than proficient with a gun. After making the cold gun his signature weapon, Leonard showed considerable aim and tactical usage of the gun, even against the Flash, able to hit his enemy, despite the former moving at superhuman speed. He is also proficient with regular weapons, such as the handgun he used before using his Cold Gun and the revolver he used in the Old West, as he could outdraw seasoned gunman who were used to using such weapons. He was shown to also be a skilled sharpshooter and sniper, as he used a rifle to shoot a gun from a man's hand from a window several buildings away.
 * Expert hand-to-hand combatant: Despite his composed demeanor, Leonard is a very capable unarmed fighter. When seemingly taken captive by a mafia boss, he and Rory quickly broke free and killed the mafia boss and most of his men with ease while his hands were still bound. His abilities are somewhat inferior to Rory's, as during their brawl after Rory's betrayal, he quickly pummeled Leonard without taking much damage himself.
 * Indomitable will/High tolerance for pain: While selfish and ruthless by nature, Leonard is a man with great conviction in any action he takes. When handcuffed to the wall by "Chronos", with almost no hesitation Leonard used his Cold Gun as means to escape, freezing his right hand and shattering it to escape. After which, despite the immense pain, he quickly sought his allies.
 * Sixth sense: Leonard is able to sense incoming danger without relying on any of his natural five senses. Even while playing cards with Sara, he was able to sense danger incoming.

Equipment

 * Cold Gun: Generating a beam of absolute zero temperature, the weapon freezes whatever it touches and creating solid ice. It can also slow down the motion of fast moving molecules, specifically those of the Flash, retarding his accelerated healing and vastly reducing his speed. It also gives off bright white and blue flashes that the user protects their eyes from with goggles.
 * Goggles: Leonard also wears a pair of blue wraparound goggles, which are designed to protect his eyes from the flashes given off by his cold gun.
