X-Universe is a Marvel actual play podcast set on Earth 699, where the story follows whatever crazy direction the GM feels like throwing into the fire. Most seasons focus on villains, not heroes, which means power grabs, selfish plans, and a lot of damage left behind. The campaign first ran on the classic FASERIP Basic Rules, giving it that old-school Marvel tabletop feel. Starting in 2026, X-Universe moves to the Marvel Multiverse Role-Playing Game, d616, for a new season of trouble. New rules, same Earth 699, and no promise that anyone is doing the right thing.
