Marvel Studios has released new teaser footage of Wonder Man as part of its 2025 programming lineup—and fans are buzzing.
Starring Yahya Abdul-Mateen II as Simon Williams, the Disney+ series is now rumored to be a key entry in the MCU’s upcoming Mutant Saga, possibly connecting to the X-Men.
While the footage offers only a brief glimpse of Wonder Man in costume, it’s already fueling speculation online. With the series set for a December 2025 release, many believe this could be Marvel’s way of subtly introducing mutant characters into the main timeline.

In Marvel Comics, Wonder Man shares a strong bond with Beast (Hank McCoy)—a prominent mutant and former Avenger. With Kelsey Grammer’s Beast confirmed for Avengers: Doomsday after his cameo in The Marvels, there's growing belief that Wonder Man could bridge the gap between mutants and the broader Avengers storyline.
Although Grammer hasn’t been announced for the series, a multiversal cameo or post-credits scene isn’t out of the question. If Abdul-Mateen’s Wonder Man crosses paths with Grammer’s Beast—either in this series or a future film—it could lay the groundwork for introducing a new X-Men team post-Secret Wars.
Past Marvel series like Ms. Marvel have already teased mutant DNA, and with Marvel heading full-speed into its Mutant Saga, Wonder Man could be the surprising launchpad for the X-Men's MCU debut.
Fans should expect more details as the Wonder Man premiere approaches, but for now, all eyes are on Simon Williams—standing at the edge of Marvel’s next major era.
