Avengers Assemble is an upcoming television series from Marvel Animation. It is the third series to be produced exclusively from Marvel Entertainment after Ultimate Spider-Man and Hulk and the Agents of S.M.A.S.H.. It is the third series to feature the Avengers after The Avengers: United They Stand and The Avengers: Earth's Mightiest Heroes.
There were rumors circulation for months that Marvel would cancel The Avengers: Earth's Mightiest Heroes and replace it with another Avengers series. A press release was released announcing that the series would not be renewed for a third season, though Marvel denied this. The same release announced Avengers Assemble for release in 2013.
It was rumored to air on Cartoon Network rather than Disney XD, though this was unlikely given that The Walt Disney Company owns Marvel. When asked about airing on XD, Jeph Loeb stated, "I think the best answer for that would be, 'Wouldn't that be fantastic?'"
On June 12, 2012 the series was officially announced, spelling the end to The Avengers: Earth's Mightiest Heroes. Earth's Mightiest Heroes had only fifty-two episodes ordered, the two seasons, and Marvel chose not to order beyond that. That series would finish in late 2012 or early 2013 with the new series beginning in 2013 along with Hulk and the Agents of S.M.A.S.H..
The series will be produced completely in-house along with Ultimate Spider-Man and Hulk and the Agents of S.M.A.S.H..
The roster showed the same line-up as The Avengers film with Captain America, Hulk, Iron Man, Thor, Black Widow, and Hawkeye though they added Falcon. Loeb and Quesada stressed that the line-up was to match the Marvel Cinematic Universe, fueling rumors that Falcon would appear in the sequel to Captain America: The First Avenger.
Falcon is meant to be the eyes of the audience. Quesada said, "He's a new member of the Avengers so he's walking through our stories wide-eyed and with wonder and amazed to be a part of it. He's a little younger than the rest of the cast and a little greener, so he adds an interesting dimension to the team that we think will play really well with the audience."
