The Marvel rumor mill is spinning at full speed once more, and this time it’s centered on one of the most beloved breakout stars from the X-Men saga: Dafne Keen. According to persistent online reports and insider whispers, the 20-year-old actress—best known for her fierce portrayal of Laura/X-23 in Logan (2017) and her recent return in Deadpool & Wolverine (2024)—is already in the UK gearing up to film scenes for Avengers: Doomsday, the massive MCU team-up directed by the Russo brothers, set for theatrical release on May 1, 2026.
The most explosive detail? Keen is said to be suiting up in the classic yellow comic-book costume that fans have begged for since her debut. The iconic black-and-yellow look—complete with the pointed mask, claws, and aggressive design—has been a staple in X-23’s comic history, and rumors suggest this version draws inspiration from Hugh Jackman‘s Wolverine aesthetic. Insiders claim Keen has been training intensively alongside Jackman himself, honing fight choreography, claw work, and the physicality needed for the high-stakes action expected in the film. Some even speculate she helped conceptualize or customize her outfit, blending elements from Jackman’s classic yellow suit with X-23’s more tactical, lethal style.
This isn’t the first time Keen’s return has been rumored. After her emotional cameo in Deadpool & Wolverine—where she reprised Laura in a multiversal team-up that thrilled fans—speculation mounted that Marvel Studios was positioning her as a key player in the post-Secret Wars X-Men integration. Avengers: Doomsday (previously titled Avengers: The Kang Dynasty before the pivot to Doctor Doom) is expected to feature a massive villain ensemble led by Robert Downey Jr.’s Victor von Doom, alongside returning heroes and newly introduced mutants. Keen’s involvement would bridge the Fox X-Men legacy directly into the MCU, giving X-23 a prominent role in the battle against Doom’s multiversal threat.
The yellow suit rumor has ignited fan excitement. In comics, X-23 first adopted a yellow costume during her time with the X-Force team and later as a full-fledged Wolverine successor, symbolizing her acceptance of the mantle. Seeing Keen in it would be a visual payoff fans have wanted since Logan‘s black tactical look. Social media is flooded with fan art, mock-ups, and debates: classic yellow with blue accents, a modern MCU redesign, or something hybrid inspired by Jackman’s suit? Posts on X, Instagram, and Reddit threads call it “the glow-up we deserve,” with many predicting it sets up Keen to fully inherit the Wolverine mantle after Jackman’s final appearances in Doomsday and Avengers: Secret Wars (May 2027).
Keen’s preparation in the UK aligns with production timelines. Avengers: Doomsday is in active pre-production, with filming expected to ramp up in early 2026 at Pinewood Studios and other UK locations. Reports indicate major cast members are already on-site for fittings, training, and table reads. Keen’s presence—especially if confirmed—would signal Marvel’s intent to weave mutants into the core Avengers narrative sooner than anticipated, accelerating the X-Men reboot in the MCU.
The actress herself has fueled the fire in past interviews, expressing enthusiasm for returning to the character and openly admiring the yellow suit from the comics. “I’d love to wear it at some point,” she said in a 2025 chat, adding that training with Jackman was “incredible” and helped her understand the physical and emotional demands of the role. Her bond with Jackman—both on- and off-screen—has been well-documented, making the training rumor feel plausible and heartfelt.
If the yellow suit materializes, it would mark a bold visual statement for the MCU’s mutant era. Unlike the grounded, tactical gear in Logan, the comic-accurate yellow would inject a splash of classic superhero flair into Reeves’ darker, more realistic style (wait—no, this is the Russo-led Avengers film, not Reeves’ Batman; the rumor ties to the main MCU). It could symbolize X-23 stepping out of Wolverine’s shadow while honoring the legacy.
Fan reactions are electric. On X and TikTok, hashtags like #X23YellowSuit and #DafneInDoomsday trend locally, with edits, AI-generated images, and countdowns to 2026. Some express skepticism—”another rumor until we see set photos”—while others celebrate: “Laura in yellow? Marvel, take my money now!” The connection to Jackman’s Wolverine adds emotional weight: a mentor-protégé dynamic that could culminate in a passing-of-the-torch moment.
For now, it’s unconfirmed rumor territory—no official word from Marvel Studios, the Russos, or Keen. But with filming reportedly imminent and the yellow suit detail too specific to ignore, the hype is real. If true, Avengers: Doomsday could deliver one of the MCU’s most anticipated mutant moments: Dafne Keen as X-23, claws out, yellow suit gleaming, ready to carve her place in the multiversal war against Doom.
The wait for 2027 just got a lot more exciting. Stay tuned—because if this rumor holds, the claws are officially out.
