The Avengers: Earth`s Mightiest Heroes As the world's most dangerous super-villains break out of the Vault, the Cube, the Big House, and the Raft, five of Earth's mightiest heroes assemble a crime fighting alliance called the Avengers. The Avengers team includes Iron Man as team leader, Ant-Man (who also assumed his Yellowjacket and Giant-Man identities during the series ), Hulk, Thor, and the Wasp.[3] Captain America, Black Panther, and Hawkeye have since joined the roster as protagonists. Ms. Marvel, Vision and The Black Widow will join the Avengers in Season 2.[4]
