Leonard Snart (Earth-1: Pre-Crisis)

"There are no strings on me."

- Leonard Snart's last words

Leonard Snart was a world class criminal active in Central City and later reformed to be a Legend. He was nicknamed Captain Cold by Cisco Ramon due to his use of the Cold Gun.

The Flame and the Frost
In 2014, Leonard Snart acquired the Cold Gun and began a series of robberies in Central City. This caught the attention of The Flash, who used his speed and the assistance of his team to outsmart Snart's sophisticated plans, though often bargained their way out of Snart's threatening attacks. Eventually, Snart partnered with Mick Rory and gave him a handheld flamethrower. Both operated as Captain Cold and Heat Wave for years in the city under a "no killing" code and often encountered The Flash, both as enemies and allies. Although the encounters usually end with their imprisonment at Iron Heights Penitentiary, they repeatedly escaped over time and continued their criminal activities.

Joining the Legion of Doom
In November 2014, Snart was recruited by the Legion.

Recruited by Rip Hunter
In 2015, Snart, alongside Mick Rory, Ray Palmer, Martin Stein, Jefferson Jackson, Kendra Saunders, Carter Hall and Sara Lance were recruited by Rip Hunter. They were then the founding members of the team known as the Legends of Tomorrow and defended the timeline.

After their first mission, Palmer made breakfast as it was stolen by Snart. Palmer attempted to take the breakfast back before Carter Hall smashed the plate on with his mace. This woke Lance from her sleep, and Palmer approached her to clean the stain from her suit. Lance threatened to break his arm, while Snart defended Palmer and placed the blame on Hall. The four soon began to hold up their weapons at each other. Gideon ordered them to stop and intimidated them by promising to open the airlock to eject them to the Temporal Zone.

After the first night on the Waverider, Snart informed Hunter that his decorative urn was used by Rory as a bedpan. The Legends soon argued about only having one bathroom on the vehicle. After Snart misfired a blast from his Cold Gun at Lance, the team began fighting each other violently. The fight was eventually broken up by Rip Hunter.

Heroic Sacrifice
As a Legend, Snart fought alongside the team against Vandal Savage's forces, eventually discovering that the Time Masters were involved in Savage's uprising. To prevent the Time Masters from manipulating the team, Snart sacrificed himself to destroy the Oculus, knocking Rory unconscious and taking his place after apologizing to him.
