Labeled “Earth’s Mightiest Heroes”, the Avengers originally consisted of Ant-Man, the Hulk, Iron Man, Thor, and the Wasp. Ant-Man had become Giant-Man by issue #2. The original Captain America was discovered trapped in ice in issue #4, and joined the group after they revived him. A rotating roster became a hallmark of the series, although one theme remained consistent: the Avengers fight “the foes no single superhero can withstand.” The team, famous for its battle cry of “Avengers Assemble!”, has featured humans, mutants, Inhumans, androids, aliens, supernatural beings, and even former villains.
