The Avengers: Earth's Mightiest Heroes, Season 2

"Unaware of the imposter in their midst, the Avengers get back to business hunting down the Masters of Evil and the remaining Breakout Super-Villain escapees. They’ll deal with the return of their most lethal enemies, Ultron and Kang. They’ll face off with new enemies like Dr. Doom, Annihilus, the Winter Soldier, and the mysterious ‘Red Hulk.’ They’ll meet some of the Marvel Universe’s greatest heroes, fighting alongside the Fantastic Four, Power Man and Iron Fist, the Sentry and Dr. Strange. Ms. Marvel and the Vision will join the team as new members. And while the Avengers have had a taste of what’s coming, the full-on cosmic invasion begins here. The Earth and the Avengers are in the crosshairs of two alien empires, the deceptive Skrulls and the militaristic Kree. Over the course of the season, the team will take on the full force of both empires, as well as dealing with the cosmic fugitive known as Korvac and the intergalactic force known as the Guardians of the Galaxy. The Avengers will be tested in every way possible; torn apart by mistrust, sent to the other side of the universe, and faced with the greatest challenge of their careers as they go to war with the Kree Empire. But waiting for them in the outer reaches of space is a foe the likes of which they’ve never faced... and quite possibly the LAST foe they’ll ever face. Galactus, Devourer of Worlds."
