X-Men Are Back in Latest "Avengers: Doomsday" Teaser

The X-Men are back in the third teaser for “Avengers: Doomsday,” which has been playing during the previews of “Avatar: Fire and Ash” screenings.

The previous clips featured Chris Hemsworth as Thor and Chris Evans as Steve Rogers.

The latest teaser, released by Marvel on Tuesday, features the return of Fox’s “X-Men” characters Professor Charles Xavier (Patrick Stewart), Magneto (Ian McKellen), and Cyclops (James Marsden).

It starts by showing Xavier’s abandoned School for Gifted Youngers, where the X-Men had called home.

Magneto says ominously, “Death comes for us all. That’s all I know for sure. The question isn’t, ‘Are you prepared to die?’ The question is, ‘Who will you be when you close your eyes?’ “.

After showing Xavier’s wheelchair and a floating chess piece, reminiscent of the ending to “X-Men: The Last Stand” where Magneto attempts to regain his electromagnetic powers while playing chess, the two frenemies are reunited and embrace.

The teaser cuts to a distraught Cyclops shooting a massive beam of red energy from his visor, in a huge display of power from his previous “X-Men” movies.

There’s also a massive leg lumbering in the distance which could be a Sentinel, the gigantic, mutant-hunting robots that are one of X-Men’s most iconic villains.

Stewart, McKellen and Marsden, who first appeared together in Fox’s “X-Men” trilogy in the early 2000s, were all confirmed as part of the Doomsday cast last year.

They will be joined by Kelsey Grammer’s Beast, Alan Cumming’s Nightcrawler, Channing Tatum’s Gambit, and Rebecca Romijn’s Mystique in “Doomsday.”

They’ll also cross paths with “Avengers” characters like Chris Hemsworth, Chris Evans, Anthony Mackie, Danny Ramirez, Sebastian Stan, Paul Rudd, Tom Hiddleston, Letitia Wright, Winston Duke, and Simu Liu.

The mega team-up will also include “Fantastic Four” stars Pedro Pascal, Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach, plus the “Thunderbolts” anti-heroes Florence Pugh, David Harbour, Wyatt Russell, Hannah John-Kamen and Lewis Pullman.

"Avengers: Doomsday" will be the big Christmas movie, premiering on December 18, 2026. Watch the teaser below.
