Long-time antagonist to The Flash, Reverse Flash, aptly named due to his ability to run really fast backwards....wait, I mean, his ability to go really slow? Oh, it's because instead of being red and yellow, he's yellow and red? Three cheers for being innovative! Anywho, Reverse Flash goes through time a lot, he helps Bill & Ted, he kills Sarah Connor, and he rides Cosmic Treadmills. Zoom!
