2. Captain Cold
Leonard Snart was always kind of a dirtbag. But when he invented a cold gun, he became more than that. He became a menace.
As Captain Cold, Snart robbed Central City blind until Barry Allen stopped him. Snart didn’t always work alone, and in fact preferred a group dynamic. He worked alongside several Legions of Doom and Injustice Leagues and also teamed up with his sister, Golden Glider, as well as the rest of the Rogues. He was typically depicted as the leader of the Rogues, and as such, usually espoused their moral code. No killing of innocents, play by the rules when fighting the Flash.
In fact, when Cold and his brethren were tricked by Inertia into killing Bart Allen, the Flash at that time, Cold tracked down the villainous child and revenge murdered him. Cold may be a bad guy, but he ain’t all that bad a guy.
He’s easily one of the best Flash villains and deserves this place on the list.
