The Avengers are a fictional team of superheroes appearing in American comic books published by Marvel Comics. The team made its debut in The Avengers #1 (cover-dated Sept. 1963), created by writer-editor Stan Lee and artist/co-plotter Jack Kirby. The Avengers is Lee and Kirby's renovation of a previous superhero team, All-Winners Squad, that appeared in comic books series published Marvel Comics' predecessor Timely Comics. 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.
