Captain Cold

Captain Cold (Leonard Snart) Is a villain from the Flash Series, The Leader of the Rogues and a member of Slade's Ensemble.

He goes by Captain Cold as he uses a freeze gun he stole from Star Labs. Even without he's dangerous as he studies potential targets for months before making his move, and describes police deployment and response time with extreme precision. He also knows how to fix his gun if anyone tries to break it.
