The most closest version to the originals comics with some new things, references and little changes on this 5 animated movies. The U.S. government passes a Superhero Registration Act, ostensibly designed to have super powered individuals act under official regulation, somewhat akin to law enforcement. However, superheroes opposed to the act, led by Captain America, find themselves in conflict with those supporting the act, led by Iron Man, with Spider-Man caught in the middle; the X-Men take a neutral stance. The superheroes in support of the law, such as Iron Man, Mister Fantastic and Ms. Marvel, become increasingly authoritarian.
