Plot Overview: A Multiversal Crisis

In Avengers: Doomsday, the Avengers, Wakandans, Fantastic Four, New Avengers, and the “original” X-Men unite to confront Doctor Doom (Robert Downey Jr.), a brilliant and dangerous mastermind threatening the multiverse. As realities collide, the heroes must navigate time-bending chaos and high-stakes battles to prevent universal collapse.
