The rumors surrounding Ryan Reynolds' Deadpool joining the Avengers in Avengers: Doomsday have been swirling, and the actor himself has addressed the speculation, albeit in a characteristically Deadpool-esque manner. While reports suggest Reynolds will appear in the film, his exact role and the extent of his involvement remain shrouded in mystery.

Adding fuel to the fire, Reynolds posted an image of an anarchy symbol over the Avengers logo on social media, leading many to believe it was a confirmation of his Doomsday appearance. However, Reynolds clarified that the image was actually a variant of a flag used in Deadpool & Wolverine, and not necessarily a teaser for Avengers: Doomsday.

In a recent interview with Entertainment Weekly, Reynolds was asked about the possibility of John Candy Easter eggs in Avengers: Doomsday, following the references in the Deadpool films. Reynolds responded with a joke, stating he had "four" Easter eggs written "at home in my PJs," but hadn't been on set to implement them. This playful response neither confirms nor denies his involvement, leaving fans to continue speculating.

The Hollywood Reporter indicated that Reynolds would appear in Avengers: Doomsday but would not be joining the Avengers team. This suggests a cameo or a role that keeps Deadpool separate from the main superhero squad. It's speculated that he'll be doing his "traditional Deadpool thing and being as chaotic as ever".

Adding another layer to the rumor mill, reports surfaced about a potential feud between Reynolds and Robert Downey Jr. on the set of Avengers: Doomsday. However, these rumors were quickly debunked, with reports indicating that the two actors have never even met in person.

Despite the uncertainty, many believe Deadpool's appearance in Avengers: Doomsday is likely, especially after the success of Deadpool & Wolverine. The film is expected to feature a massive ensemble cast, including several returning X-Men characters, making it a prime opportunity to integrate Deadpool into the larger MCU. Confirmed cast members so far include Chris Hemsworth's Thor, Pedro Pascal's Reed Richards, Vanessa Kirby's Invisible Woman/Sue Storm, Anthony Mackie's Captain America, Sebastian Stan's Bucky Barnes/Winter Soldier, Letitia Wright's Shuri/Black Panther, and Paul Rudd's Ant-Man. Several X-Men characters are also slated to appear, such as Patrick Stewart's Charles Xavier, Ian McKellen's Magneto, Alan Cumming's Nightcrawler, Rebecca Romijn's Mystique, James Marsden's Cyclops, and Channing Tatum's Gambit.

Whether Deadpool will officially join the Avengers remains to be seen, but fans can anticipate a chaotic and humorous appearance from the Merc with a Mouth in Avengers: Doomsday, which arrives in theaters on December 18, 2026.
