Is Deadpool Going To Be In Avengers: Doomsday? Ryan Reynolds’ Cryptic Tease Ignites Fan Frenzy

Is Deadpool going to be in Avengers: Doomsday? That’s the question burning through the Marvel Cinematic Universe fandom after Ryan Reynolds dropped a tantalizing Instagram post featuring the iconic Avengers logo defaced with a red anarchy symbol.

The image, shared on August 12, 2025, has sparked wild speculation about whether the Merc with a Mouth will crash the MCU’s next big team-up film.

With Deadpool & Wolverine’s massive success still fresh, fans are buzzing about what this could mean for Wade Wilson’s future. Let’s dive into the chaos and break down what we know about this potential MCU shake-up.

What Did Ryan Reynolds’ Instagram Post Reveal?

Reynolds’ Instagram post was pure Deadpool: a black-and-white Avengers logo with a red “A” anarchy symbol spray-painted over it, dripping with his character’s signature mischief.

Posted without a caption, the image left fans to decode its meaning. Some see it as a playful troll, while others believe it’s a deliberate hint that Deadpool will appear in Avengers: Doomsday, set to hit theaters on December 18, 2026.

The timing is suspicious, as filming for the film, directed by the Russo brothers, is already underway.

The post’s imagery echoes Deadpool’s irreverent style, particularly reminiscent of a scene in Deadpool & Wolverine where a similar logo appeared.

This has fueled theories that Reynolds is teasing a cameo or a larger role in the multiverse-heavy Avengers: Doomsday, which already boasts a star-studded cast including Robert Downey Jr. as Doctor Doom.

Why Does Deadpool Fit in Avengers: Doomsday?

The MCU’s multiverse saga makes Deadpool a natural fit for Avengers: Doomsday. The 2024 blockbuster Deadpool & Wolverine, which grossed $1.3 billion globally, leaned heavily into multiversal shenanigans, bringing Reynolds’ Wade Wilson and Hugh Jackman’s Wolverine into the MCU.

The film also featured cameos from Fox’s X-Men universe, setting a precedent for crossovers. With Avengers: Doomsday confirmed to include legacy X-Men like Patrick Stewart’s Professor X and Ian McKellen’s Magneto, Deadpool’s inclusion would align with the film’s multiversal chaos.

Marvel Studios president Kevin Feige has hinted at ongoing discussions with Reynolds about future MCU appearances, though no concrete plans have been confirmed. The Russo brothers’ flexible filming process, which allows for last-minute additions, further opens the door for a Deadpool cameo.

Could Reynolds Be Trolling Fans Instead?

Deadpool thrives on breaking the fourth wall and messing with expectations, so it’s possible Reynolds is just having fun. In past interviews, he’s expressed reluctance to see Deadpool fully integrated into the Avengers, arguing that the character works best as an outsider.

In April 2025, Reynolds told a major outlet that making Deadpool an Avenger could dilute his chaotic charm, suggesting he prefers Wade as a supporting player in ensemble projects.

Still, the timing of his post, coupled with Marvel’s tease that more cast members will join Avengers: Doomsday, makes a trolling explanation less likely. Fans on social media are split, with some convinced it’s a confirmation and others cautious about getting their hopes up.

What Would Deadpool’s Role Look Like?

If Deadpool joins Avengers: Doomsday, his role could range from a quick gag to a pivotal supporting part. The film’s massive cast, including Chris Hemsworth, Anthony Mackie, and Channing Tatum as Gambit, suggests a sprawling narrative where Deadpool’s humor could provide levity.

Picture Wade cracking jokes during a multiversal battle or poking fun at Robert Downey Jr.’s Doctor Doom. Alternatively, Reynolds might be saving his appearance for the 2027 follow-up, Avengers: Secret Wars, which could feature an even larger roster of heroes.

Fans are already imagining Deadpool interacting with the Avengers, perhaps riffing on his failed audition with Happy Hogan in Deadpool & Wolverine. Whatever the case, his presence would likely amplify the film’s irreverent energy.

When Will We Know More?

Marvel has remained tight-lipped about additional casting for Avengers: Doomsday, but with production ongoing, more reveals could drop soon. Reynolds’ history of cryptic teases suggests he might follow up with more hints, or Marvel could confirm his involvement through an official announcement.

Some Closing Thoughts:

Given the film’s December 2026 release, fans may have to wait for a trailer or a second casting wave to get clarity.

For now, the speculation is half the fun. Reynolds’ post has reignited excitement for Avengers: Doomsday, proving that Deadpool’s chaotic energy can shake up the MCU even from an Instagram feed.

Whether he’s trolling or teasing, one thing’s clear: the Merc with a Mouth has fans on the edge of their seats, ready for whatever madness comes next.
