Major Marvel Star’s Return Leaked? Avengers: Doomsday Could Be Even Bigger Than Expected!

Hey Marvel maniacs! The rumor mill is churning, and I just can’t keep this to myself. If you’re counting down the days to 2026’s Avengers: Doomsday (and who isn’t?), it’s time to get even more hyped—because it looks like Joe Locke’s Wiccan is about to make a surprise comeback that nobody saw coming!

Avengers: Doomsday—2026’s BIGGEST Movie?

Nobody’s debating it: Avengers: Doomsday is set to be the MCU’s biggest event since Endgame, with a star-studded reunion, multiversal chaos, and some real competition from blockbusters like Dune: Messiah and Spider-Man: Brand New Day.

With Marvel Studios wrapping up the Multiverse Saga, fans are on a wild guessing spree. Who’s returning? Who’s debuting? And most importantly, who’s going to steal the spotlight this time?

The Unexpected Leak: Joe Locke in the MCU Again?

Here’s where things get juicy. In a recent TikTok live session, legendary actor Steven Sater might have accidentally let Marvel’s secret plans slip! When fans asked about Joe Locke, Sater casually mentioned Joe’s “crazy” schedule—he’s filming the Netflix Heartstopper movie and “doing a Marvel movie.” Wait, what Marvel movie? The ONLY one currently in production is Avengers: Doomsday!
Cue Marvel fandom meltdown.

Locke, who dazzled as Billy Maximoff (Wiccan) in Agatha All Along, hasn’t been officially announced for the movie. But this clue, paired with leaked concept art showing Wiccan fighting alongside the Young Avengers, has fans convinced he’s back and ready to shake up the MCU.

Wiccan: Why This Magical Hero Matters

If you binged Agatha All Along, you know how pivotal Joe Locke’s Wiccan has become:

• He became Wiccan in the show’s penultimate episode, teaming up with Agatha Harkness to battle Death.
• His journey with Agatha—to find his brother Tommy—sets the stage for the Vision Quest spinoff.

Locke himself has teased that his Marvel future is locked in (pun intended!):

“I signed for my whole life,” he joked about his MCU contract.

Bottom line: Wiccan isn’t going anywhere, and Avengers: Doomsday may just be his major breakout.

Could the Young Avengers Assemble in Avengers: Doomsday?

Here’s another reason Marvel fans are losing their minds. Recent leaks show Young Avengers concept art, and with Doomsday being such a universe-shaking event, it would be the perfect time to unleash these young heroes. Imagine Wiccan, Kate Bishop, and Ms. Marvel sharing the screen—with rumors of a Disney+ spinoff right around the corner.

Official Cast and The Secret Sauce

Marvel’s keeping a tight lid on everything, but here’s what’s certain so far:

• Hemsworth as Thor, Anthony Mackie as Captain America, Letitia Wright as Black Panther, Florence Pugh as Yelena, and Simu Liu as Shang-Chi—all confirmed.
• OG X-Men cast like Patrick Stewart (Professor X), Ian McKellen (Magneto), and Kelsey Grammer (Beast) are back!
• Robert Downey Jr. flipping things upside-down, returning as… Doctor Doom? Let that sink in.

Production is so secret, only half the cast has been announced, and Marvel promises even bigger surprises to come.

Marvel’s Surprise Formula: What’s Next?

Locke’s possible return checks all the boxes for Marvel’s favorite playbook: keep us guessing, tease a little, leak a lot, and deliver on the big screen. With the Young Avengers buzz at an all-time high, Avengers: Doomsday could also double as their MCU team debut—and set up a new era of Disney+ adventures.
