This is another crossover I would like to see. I think I’d want it to be set during World War II, when they’re both relatively new heroes. Plus, that way you can have them fighting Nazis, who are perfect comic-book villains. I’m not sure about the story, perhaps Red Skull has found out the location of Paradise Island, and attempts to launch an invasion. Maybe this could be a two-part crossover. First, Marvel publishes Captain America/Wonder Woman, set in WWII, and then DC publishes Wonder Woman/Captain America, which would be set in modern times, after Cap is revived from suspended animation. And then they can fight some Islamic terrorists together.
For the creative team, I think I’d want either Kurt Busiek or Mark Waid. Busiek is one of the best writers in the business, and has written both characters in JLA and Avengers, so I know he could handle it. I don’t know if Waid has ever written Wonder Woman solo, though I know he’s written her in the JLA series, plus his two runs on Captain America were my favorite. For art, I think George Perez would be perfect, maybe Bryan Hitch.
