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, September 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, who appeared in comic books series published by 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, In-humans, androids, aliens, supernatural beings, and even former villains.
