Marvel fans are in overdrive after Deadpool star Ryan Reynolds dropped a cryptic Instagram post this week, reigniting speculation that the wisecracking anti-hero could appear in the upcoming mega-event film Avengers: Doomsday.
The image, which showcased the Avengers logo vandalized with bold, red graffiti in unmistakable Deadpool style, immediately went viral. The altered emblem — blending the classic Avengers “A” with anarchic street-art flair — has been interpreted as a sly nod to Deadpool’s unpredictable presence in the film. Fans flooded comment sections with theories, many convinced this was more than just one of Reynolds’ playful pranks.
Since his debut in Deadpool (2016) and its blockbuster sequel Deadpool 2 (2018), Reynolds has transformed the character into one of Marvel’s most beloved icons. His most recent outing, 2024’s Deadpool & Wolverine, shattered records with a staggering $1.3 billion global haul, marking the first time the duo shared the screen under Marvel Studios. The film cemented Deadpool’s place in the Marvel Cinematic Universe (MCU) and left fans hungry for more.
Marvel’s official cast list for Avengers: Doomsday notably omitted Reynolds, but with the film’s sprawling, multiverse-heavy narrative, many believe the omission is deliberate misdirection. Given Deadpool’s penchant for breaking the fourth wall and crashing unexpected storylines, the door for a surprise appearance remains wide open.
Production on Doomsday is well under way, with insider leaks suggesting that another major casting announcement is imminent. The film, set to release before Avengers: Secret Wars, is positioned as a critical pivot in the MCU, uniting heroes and villains from across multiple timelines.
Recent set photos have already revealed an impressive roster: Sam Wilson’s Avengers team, The Thunderbolts, The Fantastic Four, and even returning X-Men legends like Patrick Stewart (Professor X), James Marsden (Cyclops), and Ian McKellen (Magneto). These appearances have further fueled theories that Deadpool & Wolverine’s dynamic duo might reunite within Doomsday.
Still, Marvel Studios remains silent. When pressed for comment, a spokesperson simply teased that the movie would feature “some of the most unexpected alliances in MCU history.”
For now, the mystery remains unsolved. But if Reynolds’ social media history is any indication, fans can expect more winks, hints, and carefully timed chaos before the studio makes anything official. Whether or not Deadpool crashes the party, one thing is certain: Avengers: Doomsday — hitting theaters worldwide in May 2026 — already has audiences counting the days.
