A good chunk of Doomsday could focus on a clash between Avengers and X-Men with RDJ’s Doom cackling in the background, with a kidnapped Franklin by his side. The premise certainly gives the Fantastic Four a reason to breach their multiversal walls and zip over to 616 to meet the New Avengers.

The post-credits scene in Fantastic Four directly sets up Avengers: Doomsday, and there may be a nod to Iron Man you missed.
