Everyone always seems to point to the likes of Spider-Man and Batman as having the best villains, but The Flash's Rogues are right up there with many of the baddies those heroes square off with on a regular basis. Captain Cold is the leader of that team, and while The Fastest Man Alive has frequently found a way to outsmart him and his band of crooks, Leonard Snart is street smart enough to find ways of making The Flash's life as difficult as possible, pulling off some daring heists in the process. He's also one of only a handful of villains with the ability to slow Barry Allen down with his freeze gun, so Mr. Freeze has nothing on this guy.
