This is an insanely hard match as I can think of dozens of scenarios where either one of these fighters can win. Batman has obtained Superman’s abilities in the past, which is always amazing while the Flash has his incredible speed as well as a GL Power Ring so that he can fly. It’s definitely a match that you wouldn’t forget anytime soon and I believe that I will have to give it to Batman. Flash may have the edge in speed, but Superman’s speed isn’t bad and Batman’s other power ups such as Black Canary’s screech and the Yellow Lantern Ring should help to negate Flash’s speed advantage. Batman wins.
