Civil War Part 1: The Fall of Attilan
The Avengers must stop Maximus from wreaking havoc in Attilan and causing its citizens to lose control of their powers. At the same time, the Inhuman Registration Act is passed where the Avengers have their own opinion on that.
With an all-star roster consisting of Iron Man, Captain America, Thor, Hulk, Hawkeye, Falcon and, occasionally–when she feels like it and only when she feels like it–Black Widow, the Avengers are a team in the truest sense. The Avengers save the world from the biggest threats imaginable–threats no single super hero could withstand.
