The Sentry is recruited by Tony Stark to be part of the Mighty Avengers, the newest incarnation of the Avengers team. While at first there is some dispute between the Sentry and his wife, Robert joins the team while Tony Stark and Ms. Marvel offer him assistance to battle his mental issues. He is described to be the most powerful member of the team, but lacks proper training on how to use his abilities, usually apologizing for his mistakes (apologizing for damage to a building and being thrown into a blimp).
