The X-Men Return: Patrick Stewart and Ian McKellen
The most emotional part of the Avengers Doomsday X-Men trailer online is undoubtedly the return of the legendary duo. We see a ruined X-Mansion in a timeline that looks hauntingly familiar. Patrick Stewart’s Professor X and Ian McKellen’s Magneto are seen playing chess amidst the rubble, a direct nod to their history in the Fox universe.
Magneto’s voiceover is chilling: “Death comes for us all… The question is, who would you be when you close your eyes?” This suggests that the X-Men aren’t just cameos; they are survivors fighting an Incursion that threatens to wipe out their entire reality. For fans who grew up with the original trilogy, seeing these characters in comic-accurate suits is a world-class nostalgia trip.
Doctor Doom’s Master Plan: Why RDJ is Back
Robert Downey Jr. is back, but not as the hero we remember. The Avengers Doomsday X-Men trailer online highlights Victor von Doom as a “Wolf in Sheep’s Clothing.” Rumors suggest he teams up with the Fantastic Four initially to “save” the Multiverse, but his true motive is absolute control.
Doom isn’t just a villain here; he is a force of nature. In one scene, we see him standing over a defeated Sentinel, proving his dominance over both magic and technology. His goal? To fuse the dying timelines into a single world—Battleworld—where he reigns supreme.
