Deadpool Officially Confirmed for AVENGERS: DOOMSDAY

Deadpool has officially RSVP’d to Marvel’s biggest multiversal showdown. According to The Hollywood Reporter’s Heat Vision, Ryan Reynolds’ Merc with a Mouth will appear in Avengers: Doomsday, marking his first ensemble outing in the MCU. Don’t expect him to be an Avenger in the traditional sense, though—Deadpool’s role is set to deliver chaos, fourth-wall breaks, and his trademark refusal to play by Marvel’s rules. Reynolds even teased the news himself with a cheeky Instagram post days before the confirmation.

And he won’t be crashing the party alone. Avengers: Doomsday is shaping up to be the most star-studded Marvel crossover yet, pulling in heroes from across the MCU and Fox’s legacy X-Men universe. Alongside returning Avengers like Thor, Captain America (Sam Wilson), Ant-Man, and Shuri, the film boasts newcomers Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), and the long-awaited Gambit (Channing Tatum). Heavy-hitters like Patrick Stewart’s Professor X, Ian McKellen’s Magneto, Kelsey Grammer’s Beast, and a slew of mutants will join the battle, stacking this cast to multiversal-breaking levels.

With so many players on the board, Deadpool’s arrival feels like the perfect wildcard move. His irreverent, unpredictable energy will no doubt clash with Marvel’s most serious heroes while giving fans the kind of genre-bending madness only he can bring. With Avengers: Doomsday hitting theaters December 18, 2026, Marvel seems intent on delivering the ultimate crossover event—one that makes Endgame look like a warm-up.
