Raised by an abusive father, Leonard Snart found rare solace in the company of his grandfather, who drove an ice truck. Developing an experimental handgun to interfere with the Flash’s super speed, Snart accidentally irradiated the weapon and wound up with a tool that could freeze the moisture in the air. He donned a parka and goggles and declared himself Captain Cold. He became the leader of The Rogues, a group of villains banded together to oppose The Flash.
In the alternate timeline where the conflict between heroes and villains has escalated to war, Captain Cold witnesses Lex Luthor kill Superman with a kryptonite spear. Aware that, with the oncoming of Brainiac, Superman was their best hope for defeating the conqueror, Captain Cold attempts to put Superman in a cryonic freeze to revive him later, however Luthor stops him and vaporizes Captain Cold for trying.

Captain Cold is level 30 and exceedingly dangerous. While his attacks are relatively avoidable, they deal highly punishing damage. His regular attack is firing three ice boulders in rapid succession. He may launch them at an angle, and make them explode into dozens of icicles upon landing, and encase players in ice. However, his most deadly attack is a medium-ranged continuous shot of his freeze gun that hits over 400 very rapidly.
Captain Cold seems to be less dangerous here, with his continuous shot dealing less than 100 damage each hit, but he does have the encase attack upgraded considerably, being able to hold the player for very lengthy periods of time. He usually encases two players, temporarily forcing only two to combat the Rogues. Players are unable to break out.
