The Avengers: Earth's Mightiest Heroes - Season 1

When 74 of the planet’s most powerful villains break out of prison, the threat is too great for any one hero to face alone. Even S.H.I.E.L.D. cannot stop the chaos on its own. Marvel’s mightiest superheroes join forces as the Avengers, working together to capture the escaped criminals, fight evil, and defend Earth from dangers too widespread for a single champion.
