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 crime fighting alliance called the Avengers. The Avengers line-up initially includes Hank Pym (who assumes both his Ant-Man and Giant-Man alter-egos), Hulk, Iron Man, Thor, and the Wasp. Captain America, Black Panther, and Hawkeye have joined the roster and will be regulars on the show.
