Professor Charles Xavier and the original X-Men lineup have officially been confirmed to return in the blockbuster Avengers: Doomsday—a major surprise Marvel has delivered to superhero fans.

Marvel Studios recently stirred excitement by releasing the third teaser trailer for Avengers: Doomsday. In this teaser, fans were thrilled to discover that the original X-Men team from the Fox era is set to reappear in an epic battle against the supervillain Doctor Doom.

The returning cast members include Professor Charles Xavier (played by Patrick Stewart), Magneto (played by Ian McKellen), and Cyclops (played by James Marsden). This iconic trio is widely regarded as the face of the X-Men franchise, having helped propel mutant-themed films to global success in the 2000s.

The teaser opens with a bleak, desolate setting at the X-Men school led by Charles Xavier—a place where young mutants once learned to control their extraordinary powers. In a chilling voiceover, Magneto declares: “Death will come for all of us. That is the only thing I know for certain. The question is not ‘are you ready to die?’ but ‘who will you be when you close your eyes?’”

One of the most emotional moments comes when Magneto reunites with his longtime friend—and former adversary—Charles Xavier, the brilliant telepath. Now aged and no longer locked in conflict, the two share a sincere handshake, signaling reconciliation rather than rivalry.

Another scene reveals Cyclops, the mutant capable of firing powerful energy beams from his eyes, standing furious and heartbroken on a devastated battlefield.

Within just hours of its release, the teaser surpassed 7 million views on Marvel’s official channel alone. It quickly went viral across social media, drawing massive engagement and fueling anticipation among superhero fans. Many expressed their excitement for Avengers: Doomsday, envisioned as a monumental showdown uniting legendary characters from the genre’s golden era.

Previously, Marvel had already teased the return of Captain America and Thor, further heightening expectations for this cinematic event.
