THIS IS SO TRUE. When people ask me why I love Marvel or DC so much I just can't explain why I find it so amazing that every character and different worlds are all connected somehow and that there is no story that doesn't tie in.
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.
