I mean they fought each other in DC vs. Marvel in 1996 which awesome and they became friends in the excellent 1997 crossover Captain America/Batman and JLA/Avengers. Who thinks they share similarities? i always thought he was marvel's Batman since 96. Can anyone compare their combat skills, weapons, their sidekicks, Red Skull to Joker, their choice of transportation etc.? afterall we know Avengers and JLA are the same kind of team in their universes.
