Avengers: Doomsday new teaser shows return of X-Men; Hints at giant battle in MCU

Marvel Studios is gearing up fans for the highly anticipated Avengers: Doomsday, hitting theatres on December 18, 2026. The latest teaser offers a thrilling first look at the X-Men.

Avengers: Doomsday X-Men teaser

The latest Avengers: Doomsday teaser sets the stage at Xavier’s abandoned School for Gifted Youngers, where the X-Men once lived, hinting at a great battle. Magneto ominously muses, “Death comes for us all. It’s all I know for sure. The question isn’t ‘are you prepared to die?’ The question is ‘who would you be when you close your eyes?'”

The teaser also features Xavier's wheelchair and a floating chess piece, reminiscent of Magneto's chess scene in "X-Men: The Last Stand." Two old rivals share a heartfelt reunion, but things take a turn for the worse when an unstable Cyclops shoots a giant red beam from his visor. This impressive display of power hints at a more central role for him in “Doomsday.” Meanwhile, a raised foot in the distance points to a Sentinel, the legendary mutant-hunting machine.

While another commented, "Finally Marvel is doing justice to cyclops." "I hope Deadpool finally meets Ian McKellen. How happy he'll be seeing Magneto.," said another.
