Get the Flashmug. A DC Comics superhero with the ability to run at impossible speeds from sound to light. There have been lots guys to wear the costume in the past(Jay Garrick-Barry Allen)But the coolest one so far is Wally West who started off as the original Flash's sidekick. One thing about the Flash is that he makes a lot of F'ing enemies, so he famous for his Rogues Gallery.
