Abomination, orginal name Emil Blonsky, is a villain in The Avengers: Earth's Mightiest Heroes. He first made a cameo appearence in the episode, "Panther's Quest" and made his first real appearence in the episode, "Gamma World, Part One".
In "Gamma World, Part Two" he fought against Thor, Hulk, and Hawkeye alongside Leader and Absorbing Man. He was defeated by Hulk and Hawkeye and was blown away into a nearby desert area. He was then seen crawling on the ground in defeat when the Masters of Evil found him and later asked him to join.
In "Masters of Evil" he helped take over Avengers Mansion with the other members of the Masters of Evil. He and the others captured every Avenger except for Black Panther, Hawkeye, and Ant-Man. He told Baron Zemo it was a mistake to keep them alive and after being ignored he warned Zemo not to ignore him and asked why he was giving all the orders despite the fact he was the only one with no powers or strength. Zemo then knocked him down and told him the reason was because he was better than him. He was later literally kicked out of the room they were in by Giant Man. He was later betrayed along with Zemo, Crimson Dynamo, and Wonder Man by Enchantress and Executioner.
