Well, there you have it.
What character from the Marvel U would you like to see in an adventure with Big Blue and why? What villain should they fight?
Personally, I'd like to see Superman and the X-Men, fighting something big, like Thanos or perhaps some sort of evil Alien Armada.
I wouldn't mind if Superman kicked the X-Men's collective asses in the way, though.
I'd also like to see Superman teaming up with The Avengers. Perhaps fighting Darkseid.
Anyway, in short, I'd like something really, really epic, with lots of action, in a larger-than-life plot, showing the Marvel guys why Big Blue is the best (yeah, I'm such a fanboy...)
