avengers: doomsday third teaser leaks – all about the x-men return! #marvelstudios #avengersdoomsday

Following leaks of the Steve Rogers and Thor teasers (shown in theaters with Avatar: Fire and Ash), the third Doomsday teaser hit online Dec 28—poor quality bootleg, quickly taken down. It opens with a fly-through of the destroyed X-Mansion, chess between older Professor X (Stewart, militaristic suit) and Magneto (McKellen, scraggly beard), narration on death/preparation. Ends with Cyclops (Marsden) in blue/yellow 90s comic suit unleashing visor-free optic blast amid rubble, plus "The X-Men Will Return in Avengers: Doomsday" tag. This hints a ravaged mutant world (Sentinel attack? Incursion?), aligning with Days of Future Past comics—X-Men hunted near-extinction, forcing uneasy Avengers alliance vs. Doctor Doom (RDJ). 90s animated series-inspired designs delight fans. Fourth teaser (Fantastic Four/Wakanda focus) expected soon. Hype skyrockets for Dec 18, 2026 release—X-Men finally MCU proper!
