After Tony is outnumbered by the Avengers in an Argument, he leaves the Tower and is attacked by an unknown Species, when said species switches This Tony and Tony Stark from another dimension (with an entire different species, etc.) the Team now must deal with a new Tiny Stark as they help make the portal to get there's back. (Got inspiration from the Superior Stark costume, but I know nothing about Superior Stark. I own nothing except the powers and concept for AU Tony, but not actually Tony Stark.)
