Best Marvel Crossover Events of All Time

The original 1984 Secret Wars is the template for every Marvel crossover that followed: heroes and villains yanked to a Battleworld, universe-changing consequences, and the debut of the black Spider-Man suit.

The Infinity Gauntlet is Marvel's cosmic apex: Thanos with the power of a god, half the universe erased, and a desperate alliance of heroes with almost no chance of stopping him.

Civil War turned hero against hero over the Superhero Registration Act, splitting the Marvel universe down ideological lines and permanently altering the status quo.

House of M saw the Scarlet Witch reshape reality into a mutant-dominated world, ending with three words that depowered most of the mutant population overnight.

Annihilation is the event that revitalized Marvel's cosmic corner, bringing together the Nova Corps, the Guardians, and a universe-threatening wave led by Annihilus.
