Ryan Reynolds is officially back as the Merc with a Mouth in the upcoming Marvel blockbuster, Avengers: Doomsday. Fans have eagerly awaited the return of Deadpool to the Marvel Cinematic Universe after his smashing debut alongside Wolverine in 2024’s Deadpool & Wolverine.

While Deadpool will make an appearance, don’t expect him to formally join the Avengers squad just yet. Sources confirm that Reynolds’ character will remain the lovable outsider, bringing his signature humor and chaos to the massive ensemble without becoming an official Avenger.

Avengers: Doomsday promises to unite fan-favorite heroes for a universe-colliding showdown hitting theaters December 18, 2026. With an incredible cast lineup and Deadpool’s unexpected cameo, this film is shaping up to be a thrilling ride for Marvel fans everywhere.
