The Avengers: Earth's Mightiest Heroes Wiki

Gamma World, Part 2 is the thirteenth episode of Season One of Avengers: Earth's Mightiest Heroes and the overall series, as well as the second part of the double-length episode.


With the Avengers, minus Ant-Man, turned into Gamma Monsters, Hawkeye must convince the Hulk to help fight the Leader and the Abomination while Thor (who was unaffected by the Gamma Dome when he is Asgardian) fights the Absorbing Man.


After capturing the U-Foes, Zzzax, and the Wrecking Crew, The Leader sets up another gamma dome, undoing the apprehension of the villains as it turns the Avengers and S.H.I.E.L.D. agents again into Gamma Monsters. Black Widow knew the Avengers were inside thinking it was hopeless, but Hawkeye knew there was only one hope; Hulk. After leaving Natasha tied up to where the dome is expanding, Hawkeye rescues the Hulk from Ross' forces and gets him to provide an antidote to protect him from the dome.

The Leader was in Las Vegas up in the Space Needle as his base of operations as Abomination brings in a captured Thor and unconscious Doc Samson. The Leader asks Thor why he isn't turning into a gamma monster like the ones in the dome, Thor explains that his life force is highly immune to mutations and diseases. Thor then retrieves his hammer in which Absorbing Man takes on the form of his hammer and tackles him outside of the building, then Hulk and Hawkeye arrive fighting Abomination and the gamma-mutated Avengers.

Hawkeye first cures Wasp and then the others just before Sterns engages him in a robot mech. Thor outwits Crusher by manipulating him while he is composed of the essence of his hammer. After Hulk punches Abomination out of Las Vegas, Thor sends Absorbing Man into the Leader defeating them both. Finally, Hulk lifts up the machine that shuts down the dome and throws it into the sun, returning everyone back to normal. Hawkeye was cleared and Hulk rejoins the Avengers in a condition if Hawkeye stays too, that frustrated him. Somewhere in the desert, Abomination met up with Zemo and the Masters of Evil saying his real name: Emil Blonsky.
