The Avengers: Earth's Mightiest Heroes

Season One

As 75 of the world's most dangerous super-villains are mysteriously freed en masse from 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 is composed of Iron Man (Tony Stark) as de facto team leader, Ant-Man/Giant-Man (Hank Pym), the Hulk (Bruce Banner), Thor, and the Wasp (Janet Van Dyne) Captain America (Steve Rogers) joins the team later after being found frozen in ice while the team is looking for a missing Hulk. Although other characters feature in the Avengers, these are the original and main avengers. Future members of team for season one include Black Panther (T'Challa) and Hawkeye (Clint Barton). In the season finale, it is revealed that Thor's adopted brother Loki was responsible for the breakouts and that he had the Enchantress and her servant under his control.

Season Two

Season Two uses cold openings, and remixes opening theme song "Fight As One", replacing the lyrics with Nick Fury, voiced by Phil LaMarr, introducing the show's concept and main characters. Season Two depicts the Avengers as they track down the remaining members of the Masters of Evil and end up facing the invasions of the Skrulls in the first half of the season and the Kree in the second half. The Avengers are unaware that Captain America had been replaced at the end of the first-season finale by a Skrull operative as part of their systematic infiltration of Earth. This season also alludes to a developing storyline that Surtur, now free of his imprisonment in Muspelheim, is slowly gathering his strength to oppose the Avengers as a prelude to Ragnarök. Ms. Marvel joins the team this season, followed by the Vision. Many other characters from the Marvel Comics universe, such as Spider-Man, Wolverine, Scott Lang (the second Ant-Man) and his daughter Cassandra, Heroes for Hire, Doctor Doom, Crossfire, Thaddeus E. "Thunderbolt" Ross (in both his human form and his "Red Hulk" form), the Guardians of the Galaxy (composed of Star-Lord, Rocket Raccoon, Groot, Quasar and Adam Warlock), Quake, Beta Ray Bill, the Falcon, the Winter Soldier, and Galactus and his heralds, make appearances. Series producers Joshua Fine and Christopher Yost have revealed that certain returning characters will adapt their Ultimate Universe counterpart costumes for the second season, such as Nick Fury appearing more like Ultimate Nick Fury with a shaven head and goatee, and the Skrull operative posing as Captain America wearing the costume directly adapted from Ultimate Captain America and wielding an energy shield. The second-season premiere, titled the "The Private War of Dr. Doom" (featuring Dr. Doom and the Fantastic Four), was shown to audiences at both the 2011 San Diego and New York Comic Cons, as well as the 2012 WonderCon in Anaheim. It premiered with the two-part Ultimate Spider-Man pilot on April 1, 2012.

The series started airing on Marvel's sister network, Disney XD in the United States on October 20, 2010 and on Teletoon in Canada on October 22, 2010 in English-language and March 2011 in French-language. According to Jeph Loeb, Season 2 will presumably begin around October 2011, same as season 1 and Producer Josh Fine tweeted in April 2011 that 13 episodes have been completed. At the 2011 New York Comic-Con, Marvel TV director, Jeph Loeb contradicted his earlier statement of Season 2 launch in late 2011. Loeb announced at the panel at New York Comic-con that "Avengers Season 2 will be coming in early 2012 (to coincide with Ultimate Spider-Man)." This date would later get clarified to April 1, 2012.

Future of series

A new Avengers show premiered in 2013 called Avengers Assemble. On Saturday, July 14, 2012 at the 2012 Marvel Television Presents panel at San Diego Comic-Con, Jeph Loeb, Head of Marvel Television, said of the relationship between the two shows:

"We're not in any way saying Earth's Mightiest Heroes never happened. You will see an epic conclusion. And then you'll say, 'Oh, what's next?'"

Only Hulk's voice actor Fred Tatasciore reprised the role for Avengers Assemble, as well as Spider-Man's voice actor Drake Bell for guest appearances, while the other members of the team share their voices with their counterparts in the separate Ultimate Spider-Man series.
