7. Fantastic Four: Acts of Vengeance

(Fantastic Four #324-326)

Acts of Vengeance is one of the all time great crossover ideas. All of the villains got together and decided to just switch heroes.

Ultron took on Daredevil, Vulture fought the New Mutants, a buncha D-list Avengers foes took a crack at Spider-Man…You get the idea. But the best one was a part of the Simonson Fantastic Four run.

In the story, the FF are in court, battling a new superhero registration act (decades before Civil War, I might add). But F-list villains from across the Marvel Universe keep interrupting their case. And, of course, the Fantastic Four, who have already beaten the almighty force of universal destruction multiple times, very easily beat them. It's really funny.

It's one of the funniest Marvel stories of its era, and although it isn't easy to find collected unless you wanna pay top dollar for an omnibus like I did, it's well worth it to track down the issues.
