Like most fans out there, I love a good inter-company crossover. There is something really exciting about seeing favourite characters that cannot interact normally on the same page. Sure, we've had some duds like Marvel vs DC, which was ambitious but any comic that shows Wolverine beating Lobo gets a big thumbs down from me, but we've also had some gems like X-men/Teen Titans and JLA/Avengers.
It is in that vein that I'd love to see the following crossovers, but since there wouldn't be enough explosions and cosmic peril I doubt they would ever see print.
Justice League International (Giffen/Dematteis) and the Great Lakes Avengers - This would simply be comic gold, playing these teams up together. I could easily see a card tournament breaking out when these teams get together, with the loser having to accept G'Nort onto their roster!
Captain Marvel and Power Pack - Power Pack is a group of kids trying to make it as superheroes in an adult world. Captain Marvel is a kid who can transform into an adult. I think the potential for a really fun and poignant all ages tale is here just waiting to be exploited.
Edwin Jarvis and Alfred Pennyworth - We've had the Justice League battle it out with the Avengers, but now I'd love to see these two gentlemen's gentlemen sit down for a spot of tea to swap war stories. This would have been a great back-up feature to JLA/Avengers.
I could go on and on regarding this subject, but what about you? What crossovers have you always wanted to see?
