Ryan Reynolds has cast doubt on the possibility of Deadpool joining the Avengers or the X-Men, suggesting that such a move would signify the character's "end." Despite the success of Deadpool & Wolverine and Deadpool's in-film desire to join the Avengers, Reynolds remains firm. "If Deadpool becomes an Avenger or an X-Man, we're at the end," he told Time. "That's wish fulfillment, and you can't give him that."
Speculation had been rife that Marvel Studios might want the 'Merc with a Mouth' to team up with iconic characters like Captain America and Professor X for next year's Avengers: Doomsday. However, Reynolds hinted that a surprise cameo might be more fitting, citing the positive fan reception to Wesley Snipes' cameo as Blade in Deadpool & Wolverine.
The cast reveal for Avengers: Doomsday last month included a significant number of veteran X-Men actors, such as Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden. This has led to speculation that the film might secretly be an Avengers vs. X-Men movie. Grammer, who played Beast in the Fox X-Men franchise, made his MCU debut in The Marvels' post-credits scene. Stewart, who portrayed Charles Xavier/Professor X, had a brief appearance in the MCU in Doctor Strange in the Multiverse of Madness. Meanwhile, McKellen (Magneto), Cumming (Nightcrawler), Romijn (Mystique), and Marsden (Cyclops) are yet to make their MCU debuts.
Reynolds was notably absent from the Avengers: Doomsday cast list, while Channing Tatum, who played Gambit in Deadpool & Wolverine, did make the cut. As for Deadpool's future, Reynolds is currently working on a new project that involves an "ensemble," though he remains tight-lipped about the details. This could hint at another Deadpool movie with numerous cameos, similar to Deadpool & Wolverine. Other actors who appeared in the film include Jennifer Garner as Elektra and Dafne Keen as Laura Kinney/X-23, suggesting potential returns.

Details about Avengers: Doomsday remain sparse beyond the cast list. Anthony Mackie, who will reprise his role as Sam Wilson/Captain America, recently expressed optimism, stating that the film aims to recapture the "old Marvel feeling" fans cherished. Mackie joins other cast members like Paul Rudd (Ant-Man) and Joseph Quinn (Human Torch) in sharing their enthusiasm for the upcoming Marvel epic.
An alleged set photo leak from Avengers: Doomsday has also sparked discussions among fans, with some interpreting it as a bad omen for the X-Men. Meanwhile, speculation about Oscar Isaac's potential appearance as Moon Knight in Avengers: Doomsday has intensified, especially after his withdrawal from the Star Wars Celebration event due to changes in his production schedule.
Marvel Studios producer Kevin Feige has clarified that the recent Avengers livestream did not feature the complete cast of Doomsday, hinting at more surprises to come. "We revealed many, not all," Feige stated during a video call at CinemaCon.
