Wasp: We can be Avengers.
Hulk: Huh. Good name.
The Avengers: Earth's Mightiest Heroes! is a show on Disney XD, based on the Marvel Comics series as well as the superhero team The Avengers. The original head writer was Christopher Yost, who developed the show along with producer Josh Fine, as well as Ciro Nieli.
The series begins with a mysterious, massive breakout at each of the world's four super-villain prisons, releasing a horde of super-powered criminals upon the world. Brought together by the massive threat posed by the escaped Graviton, the team known as the Avengers are born — they are the Earth's Mightiest Heroes!
Originally, the team consists of Iron Man, The Mighty Thor, Ant-Man, The Wasp, and the Incredible Hulk, with Captain America, the Black Panther, Hawkeye, Ms. Marvel, and a host of other heroes ready to join them. Together, they deal with such threats as the terrorist organization HYDRA, the mystical trickster god Loki, the shapeshifting Skrull aliens, and many more. In terms of overall tone and style, the series is based principally on the original stories by Stan Lee and Jack Kirby. The series also uses material from all eras of the comic's run as well as other sources, such as the Ultimate Universe and the Marvel Cinematic Universe.
The series premiered on October 20th, 2010. Prior to this, Disney XD premiered a series of micro-episodes to introduce us to the series. Combined with the actual series, they all add up to two seasons with twenty-six episodes each. The series finale has an airdate of November 11, 2012. note Was followed by Avengers, Assemble!, though the two do not share continuities. Two series of tie-in comics also exist: A four-issue miniseries, and a series of additional comics published under the "all-ages" Marvel Universe banner. (Tropes for the comics can be found at The Avengers: Earth's Mightiest Heroes!). The show even has a tie-in online Artillery Game, The Avengers: Bunker Busters.
This is the second attempt at The Avengers having their own animated series, the short-lived The Avengers: United They Stand being the first.
Not to be confused with the mid-2000s comic series The Avengers: Earth's Mightiest Heroes!
