Leader (Yost Universe)

The Leader appeared The Avengers: Earth's Mightiest Heroes voiced by Jeffrey Combs. In the episode "Hulk Verses the World", Leader is shown as an inmate of the Cube. In the episode "The Breakout" Pt. 1, Leader is among the inmates that escape from the Cube. He manages to take it over after Hulk leaves with Doc Samson. In the two-part episode "Gamma World," Leader plans to blanket the Earth in Gamma Energy causing anyone exposed to it to become Gamma-based monsters. Unfortunately, it couldn't affect Thor or Doc Samson (who had already been exposed to it). Though the generator at the Cube was destroyed, Leader had another one in a nearby city. When Thor and Doc Samson had been taken prisoner, Leader found out from Thor that Gamma Energy doesn't affect Asgardians and unleashes Abomination on him. When Thor does regain Mjolnir, Leader summoned Absorbing Man who ended up absorbing the properties of Mjolnir. When Hulk and Hawkeye arrived, Leader had Abomination fight Hulk while he and the Gamma-powered Avengers attacked Hawkeye. Hawkeye launched special arrows that cured the infected Avengers before fighting Leader. After Hulk had defeated Abomination by sending him flying and Thor had defeated Absorbing Man, Leader's battle-suit was taken down as his head expanded a little bit while Hulk threw the Gamma Generator into space. The next day, Leader and Absorbing Man were taken into S.H.I.E.L.D. custody with the other Gamma-based villains
