Joe Locke Rumored to Return as Wiccan in 'Avengers: Doomsday' After TikTok Slip

Joe Locke is rumored to return as Wiccan in ‘Avengers: Doomsday’ after a TikTok comment and leaked concept art surfaced.
Joe Locke may be making a surprise return to the Marvel Cinematic Universe, and the clues are starting to add up. The Heartstopper star, who debuted as Wiccan in Agatha All Along, is rumored to appear in Avengers: Doomsday, Marvel’s major Phase Five film due in 2026.
The rumor kicked off after playwright Steven Sater casually mentioned in a TikTok live that Locke is currently filming a “Marvel movie” alongside the upcoming Heartstopper film. With Doomsday as the only known Marvel project in production, fans were quick to speculate.
Leaked concept art showing Wiccan fighting with the Young Avengers has only intensified theories. While the Russo Brothers have denied the art is tied to their version of the film, it’s added to the growing buzz.
Locke hasn’t confirmed anything, though he once joked he “signed his whole life away” to Marvel—a comment that might’ve been more literal than fans thought.
