I did write an article about "Marvelous Detectives." I decided that the protagonist would be Spiderman, but the plot centers around Batman, Wonder Woman, and Superman in Acts I, II, and III respectively.
Sorry for the late reply. I imagined Disney and Marvel would meager at one point in 2009 given they already had a common rival, being Warner Brothers and DC Comics. I did imagine a cartoon fighting game like Super Smash Brothers but with Mickey, his friends, and the Looney Tunes with all the Disney/WB references.
I also thought about a more dramatic game by Disney, WB, and possibly even Rockstar which I finally decided to title, "Marvelous Detectives."
