The Ultimate Vampire Resource and Directory

The Avengers: Earth's Mightiest Heroes is an American cartoon series by Marvel Animation based on the Marvel Comics superhero team the Avengers. The show debuted on Disney XD in Fall 2010 starting with a 20 part micro-series.
The series initially features a team based on the roster for the original Avengers, composed of Ant-Man, Captain America, Hulk, Iron Man, Thor, and the Wasp. In terms of tone and style, the series will be based primarily on the original stories by Stan Lee and Jack Kirby. However, it will also utilize material from all eras of the comic's run and other sources such as the Marvel Cinematic Universe.

As the world's most dangerous supervillains break out of the Vault, the Cube, the Big House, and the Raft, six of Earth's mightiest heroes assemble a freedom fighting alliance called the Avengers. The Avengers line-up initially includes Hank Pym (who assumes both his Ant-Man and Giant-Man alter-egos), Captain America, Hulk, Iron Man, Thor, and the Wasp. Black Panther and Hawkeye will join the main roster as the series progresses.
