Ryan Reynolds has sparked speculation about the future of Deadpool in the Marvel Cinematic Universe, casting doubt on the possibility of the character joining the Avengers or the X-Men. In an interview with Time, Reynolds stated, "If Deadpool becomes an Avenger or an X-Man, we're at the end. That's wish fulfillment, and you can't give him that." This comes on the heels of the success of Deadpool & Wolverine, where Deadpool's desire to join the Avengers was a central plot point.

The cast announcement for Avengers: Doomsday last month featured a significant number of veteran X-Men actors, including Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden, leading some to speculate whether the film could be a covert Avengers vs. X-Men storyline. Grammer, who portrayed Beast in the Fox X-Men films, made his MCU debut in The Marvels' post-credits scene. Stewart, known for playing Charles Xavier/Professor X, appeared briefly in the MCU in Doctor Strange in the Multiverse of Madness. Meanwhile, McKellen, Cumming, Romijn, and Marsden have yet to make their MCU debuts.

Despite the absence of Reynolds' name from the Avengers: Doomsday cast list, he hinted at the possibility of Deadpool making a surprise cameo in a supporting role, citing the positive fan reaction to Wesley Snipes' cameo as Blade in Deadpool & Wolverine. Reynolds suggested that such appearances might be more fitting for the character.

Looking ahead, Reynolds teased that he is currently writing a new project involving an "ensemble," though he remained tight-lipped on the details. He emphasized his preference for keeping Deadpool "isolated," suggesting that the next film could feature numerous cameos similar to Deadpool & Wolverine. Potential returnees might include Snipes as Blade and Channing Tatum as Gambit, along with Jennifer Garner's Elektra and Dafne Keen's Laura Kinney/X-23.
