The Greatest Comic Book Battles #7: DC vs Marvel - It's happened once where a voting system weighed the outcome who should win. Let's do it again with the most updated roster of heroes and maybe lets pit the villains with Doomsday vs the Hulk or the Juggernaut. And we can stick with George Perez's art as in this Avengers vs Justice League. Of course other comic book artist legends are welcome.
Marvel vs DC To be honest, I think they're going a bit overboard with the whole changing gender and race of popular superheroes. I don't need them to change anything about them. They could make new superheroes with the same look and everything, but new stories and character traits. I don't want a bunch of different versions of the same character. I do prefer Marvel over DC though.
