Avengers
The Avengers are a superhero team, consisting of many of Marvel Comics' most popular heroes. They first appeared in The Avengers #1 (September 1963) more...
Known for their rallying cry “Avengers Assemble!” and nickname “Earth’s Mightiest Heroes,” the Avengers is an answer of sorts to DC Comics' all-star Justice League. The team originally featured Ant-Man, Wasp, Thor, Iron Man and the Hulk, all of whom were popular, previously established superheroes. A rotating roster has been a hallmark of the team and other heroes who have had long histories as Avengers include Scarlet Witch, Quicksilver, Hawkeye, Vision, Black Widow and the team’s leader Captain America.
Unlike the Justice League, The Avengers have rarely featured a who’s who of Marvel heroes. Although more solitary heroes—such as the Hulk and Spider-Man—and heroes associated with other teams—such as The Thing and Wolverine—have had brief histories with the team, most Avengers line-ups feature both headlining characters and characters primarily known as Avengers.
The series has dealt with diplomacy as the Avengers have received official recognition or at least consideration from the United States government and/or the United Nations. Although members of the team have varying degrees of humanity—human champions, ancient gods, genetic mutants, androids and scientifically enhanced humans have been parts of the team—the Avengers have had to learn to get along with each other and interact with the human world. Stories explored the meaning of what it means to be human or superhuman and the role and responsibilities of superheroes.
