Doomsday’s credits hint that Deadpool and Wolverine may make an appearance Image: Marvel Sign in to your Polygon.com account Doctor Doom arrives in a little over a month, and at this point it feels like we have a good grasp of the main players in Avengers: Doomsday. Disney just posted a rundown of the characters central to the story, with the obvious ones being the original MCU Avengers Steve Rogers, and Thor. Beyond that, the film will also center on Sam Wilson (the new Captain America), Ant-Man, and Shang-Chi. The Fantastic Four will have a prominent role as well, which makes sense considering Victor von Doom originates from that supergroup’s comics. The New Avengers from Thunderbolts will appear alongside Wakandans like Shuri. While the trailers for the film have revealed that the X-Men will have a prominent spot in Doomsday, it won't be the versions of the characters appearing in the MCU’s upcoming X-Men film. Doomsday will reunite the mutants from the early-2000s 20th Century Fox X-Men trilogy. Patrick Stewart will appear in his final role as Professor X, Ian McKellen is returning as Magneto, and James Marsden is Cyclops. Who else may make cameos in Doomsday? Beyond these confirmed returning characters, writer credits for Avengers: Doomsday spotted by DiscussingFilm hint that two more beloved mutants may appear in the movie. The Writers Guild of America West's credits page for Avengers: Doomsday lists both Ryan Reynolds and Hugh Jackman as handling “Additional Literary Material: (not on-screen).” That descriptor is used for writers who contribute to part of a script, working on intermediate drafts or punch-ups, but who didn’t write the majority of the final screenplay. Ryan Reynolds’ existing WGA credits are for Deadpool 2 and Deadpool & Wolverine, both of which he co-wrote and starred in as Deadpool. Jackman doesn’t have any existing WGA writer credits, but he’s known for portraying Wolverine. While these writing credits don’t confirm that the pair will appear in the film, both Reynolds and Jackman made promotional appearances for Doomsday, including at D23, which some have taken as evidence they will be in the movie. Reynolds also fueled speculation last year when he posted an Avengers logo covered in graffiti on Instagram. The cameos would make sense from a storytelling perspective. While the original Wolverine from the 20th Century Fox films died in Logan, Deadpool befriended an alternate-universe doppelgänger in Deadpool & Wolverine. Considering that Avengers: Doomsday seems to be a send-off to the 20th Century Fox X-Men movies, and Wolverine was the most prominently featured character across those films, it would make sense for Jackman to make another appearance. We’ll find out for sure when Doomsday arrives in theaters on Dec. 18, 2026.
