5. Rotworld

The Jeff Lemire-written Animal Man and the Scott Snyder-written Swamp-Thing are two of the best New 52 DC comics. And they crossed over about a year in!

Both deal with The Rot, an encroaching mass of death and decay masterminded by Anton Arcane. The crossover starts with a prologue, then splits off into two separate storylines. In The Red Kingdom, Animal Man uses his animal powers to seek out heroes like Steel and Beast Boy to take out Arcane, while The Green Kingdom stars Swamp-Thing as he traces his route through Gotham and the Man-Bat filled Batcave.

Eventually, the heroes meet up again to fight Arcane and defeat his Rotworld, once and for all. Oh, and there are also some tie-ins with the Frankenstein, Agent of S.H.A.D.E. series. But for a two book crossover, this one’s pretty fun.

Lasting Impact: Arcane continues to be a threat in Swamp-Thing, and Animal Man continues the battle against The Rot. Nothing super much other than that, though.
