Marvel's Avengers is an ever-expanding hero game that will add new playable characters over time. At launch, playable characters include Captain America, Iron Man, Thor, Black Widow, Hulk, and Ms. Marvel. They are iconic Avengers characters and we know Hawkeye and his protégé Kate Bishop will be on their way soon, but another key member of the Avengers in the past has been Ant-Man. Is he present in this new story?
We knew at least one of the Ant-Men would be making an appearance in Marvel's Avengers since the game's launch. Hank Pym was revealed in a War Table feed and has a significant impact on the story with his handling of the anthill, a faction of Inhumans resisting against MODOK and AIM.
As long as Hank Pym is in the game, he is not playable and probably never will be if we can believe the story of the game. When Kamala first meets Hank, she notes that he is Ant-Man. . He replies that it's a different life than he has now, although he continues to make projects with the Pym Particle technology he is famous for. We learn in the campaign that if Hank used the Pym particles on himself to shrink again, he would die.
With Hank Pym not being able to don the Ant-Man costume again, this leaves room for Scott Lang, the Ant-Man in the movies, to potentially make an appearance as a playable character. There have been rumors and leaks of Ant-Man coming as a playable character, so this would probably be the most likely course for Pym to continue leading the Resistance. We're talking about a comic book story here, so there's always a chance Pym will improve, but Lang most likely showing up is the best chance to happen.
Everything stated above is pure speculation, as nothing has been officially announced regarding Ant-Man as a playable character in Marvel's Avengers. Be sure to come back to this article if anything new appears.
