After another international incident involving the Avengers, world leaders and political powers move to get the Avengers to be registered in lieu of previous missions that have caused collateral damage. This results in the Avengers having to decide whether to remain free or to be registered. It also results in two factions with one led by Captain America, who believes that heroes should remain free and the other led by Iron Man, who surprisingly begins supporting government regulation and oversight.
