Help me find an episode friends!
Pretty sure this wasn't from x-men, but there's an episode with an old bunch of superheroes who have to come back together, pretty sure they were all bound by rings, anyways when some bad guy tries to come for an artifact, there is a homeless man/bum sleeping in the alleyway. After this old group of hero confronts them, and is about to lose, the bum takes off his cape and 'SCREAMS' in sonic waves to drop all the heroes.
Anyone remember any other details that I can find this episode in?
