Marvel’s teaser rollout for Avengers: Doomsday is deliberately fragmented: slowly revealing returning Avengers and FOX-era X-Men, but other fake AI footage suggests Robert Downey Jr. returns as a Tony Stark variant that assumes Doctor Doom’s role. So what’s real and what’s not when it comes to the official Avengers: Doomsday trailers and the leaked footage?
Here’s a breakdown of all the Avengers: Doomsday characters who have appeared in official teaser trailers vs. those shown in leaked footage so far — plus what’s just confirmed or expected from cast announcements.
•Trailer 1 (Steve Rogers): Released December 18, 2025. It features the return of Chris Evans as a version of Steve Rogers, seen in a domestic setting with a child.
•Trailer 2 (Thor): Released December 25, 2025 (online Dec. 30). It shows Chris Hemsworth as Thor praying to Odin for the strength to face a final enemy.
•Trailer 3 (X-Men): Released January 1, 2026 (online Jan. 6). This teaser focuses on the Fox-era X-Men, including Professor X (Patrick Stewart), Magneto (Ian McKellen), and Cyclops (James Marsden) in a standoff against Sentinels.
•Trailer 4 (Wakandans/Fantastic Four): Now available online, the latest official trailer features Shuri (Letitia Wright), Namor (Tenoch Huerta), and Ben Grimm, aka The Thing (Ebon-Moss-Bachrach), from the Fantastic Four.
A full-length trailer is rumored to debut during Super Bowl LX on February 8, 2026.
Characters Seen in Leaked Trailers / Clips
These are characters seen in footage that leaked online before or after official trailer drops — not yet officially released by Marvel in an announced trailer:

Other leaks circulating online (fan discussions and threads) claim dozens of characters — including Spider-Man variants, Gambit, and others — but these are unverified until officially released trailers or Marvel announcements confirm them. The “Tony Stark as Doctor Doom” images trending on social media are almost certainly AI or fan-made fakes, not real photographs from the Avengers: Doomsday set. Real leaks so far are limited to low-resolution teaser clips that have appeared before official releases.
