The Avengers: Earth's Mightiest Heroes (Seasons 1–2)

The Avengers: Earth's Mightiest Heroes (2010) — watch online on iFILM: a Marvel animated series that assembles Iron Man, Thor, Hulk, Captain America and more into a team that none of them particularly wanted to join. Voiced by Eric Loomis, Brian Bloom, Rick D. Wasserman and Colleen O'Shaughnessey.

The trigger is a simultaneous jailbreak across four maximum-security super-villain prisons. Dozens of dangerous criminals loose at once, and S.H.I.E.L.D. already overwhelmed. Each hero has their own way of doing things — and their own reasons not to trust the others. Making that team work is as much of a challenge as stopping the villains.

The series ran two seasons from 2010 to 2012. It draws heavily from classic 1960s Marvel storylines and treats its characters seriously enough to work for adults, not just kids. Watch all episodes of The Avengers: Earth's Mightiest Heroes online on iFILM.
