“Phoenix vs. Scarlet Witch!” Famke Janssen’s Rumored Return as Jean Grey in Avengers: Doomsday Sets Up an Epic Multiversal Clash with Wanda Maximoff—Find Out Why This Marvel Showdown Is Sending Fans Into a Frenzy!
The Marvel Cinematic Universe (MCU) is ablaze with excitement following unverified claims on X that Famke Janssen, the iconic Jean Grey from Fox’s X-Men films, is officially confirmed to return as the telepathic mutant in Avengers: Doomsday (set for release May 2026), where she’s rumored to face off against Elizabeth Olsen’s Wanda Maximoff, the Scarlet Witch. The speculation, fueled by posts like @AchillesDVR’s April 2025 claim, suggests Janssen’s Phoenix will clash with Wanda in a multiversal battle, pitting two of Marvel’s most powerful women against each other. While Marvel Studios has not confirmed Janssen’s involvement, the rumor builds on earlier reports of her potential return in Avengers: Secret Wars (May 2027) and aligns with the MCU’s expanding multiverse narrative, including Robert Downey Jr.’s Doctor Doom. Fans are divided, with some thrilled at the prospect of a Jean Grey-Wanda showdown, others skeptical of the rumor’s validity, and many concerned about the treatment of legacy X-Men characters in Doomsday. As anticipation mounts, this rumored casting could redefine the MCU’s Multiverse Saga.

A Phoenix Rising Again?
Famke Janssen, who portrayed Jean Grey/Phoenix in five X-Men films from 2000 to 2014 (X-Men, X2, X-Men: The Last Stand, The Wolverine, and Days of Future Past), is no stranger to the multiverse’s revolving door. Her character, a telepathic mutant bonded with the cosmic Phoenix Force, met various fates in Fox’s timeline, from death in The Last Stand to resurrection in Days of Future Past (SlashFilm, April 2, 2025). Posts on X, including @AchillesDVR’s “JEAN GREY RETURNS!” and @MarvelSpoiler’s claim of Janssen in “final talks” for Doomsday and Secret Wars, have reignited speculation that she’ll reprise Jean Grey in the MCU (X, April 23, 2025; X, April 1, 2025). A 2022 Giant Freakin Robot report also claimed Janssen would cameo in Secret Wars, suggesting a multiversal role (Giant Freakin Robot, December 29, 2022).
The rumor of a Jean Grey-Wanda Maximoff face-off stems from fan anticipation and earlier speculation about Doctor Strange in the Multiverse of Madness (2022), where fans hoped Wanda would battle a Fox-verse character like Jean (MovieWeb, August 26, 2021). Although that didn’t materialize—Wanda decimated the Earth-838 Illuminati, including Patrick Stewart’s Professor X—the idea persists, with X users like @sociedadexmen hyping a Doomsday showdown (X, March 28, 2025). The Russo Brothers, directing Doomsday and Secret Wars, have teased a massive cast, with The Hollywood Reporter noting Marvel is “not done with reveals” (The Hollywood Reporter, April 2025). This fuels speculation that Janssen could join confirmed actors like Downey (Doctor Doom), Benedict Cumberbatch (Doctor Strange), and James Marsden (Cyclops) (CBR, April 4, 2025).
However, the rumor’s validity is questionable. No official Marvel statement confirms Janssen’s involvement, and Elizabeth Olsen recently stated she’s not set to return as Wanda for Doomsday or Secret Wars (ComicBookMovie, March 25, 2025). A conflicting rumor from SuperHeroHype suggests Olsen may reprise Wanda as Earth-616’s Scarlet Witch, potentially aligning with the Jean Grey clash (SuperHeroHype, January 7, 2025). The lack of concrete evidence, coupled with Doomsday’s filming start in March 2025, keeps Janssen’s return speculative (SuperHeroHype, January 7, 2025).
The Dream Matchup: Phoenix vs. Scarlet Witch
The prospect of Jean Grey facing Wanda Maximoff has long captivated fans, given their status as Marvel’s most powerful female characters. Jean, an Omega-level mutant, wields telepathy, telekinesis, and the Phoenix Force, which grants near-limitless power, as seen in X-Men: The Last Stand (ScreenRant, December 23, 2023). Wanda, empowered by Chaos Magic and the Mind Stone, can alter reality, manipulate minds, and traverse the multiverse, as shown in Multiverse of Madness (LiveAkhbar, November 22, 2022). A ScreenRant analysis posited that a live-action battle between them could be the MCU’s “biggest” yet, with Wanda’s reality-warping edge potentially outmatching Jean’s raw power unless the Phoenix Force is fully unleashed (ScreenRant, December 23, 2023).
X posts amplify the hype, with @rarestdreams tweeting in 2021, “If Jean Grey makes her MCU debut by getting in a cosmic showdown with Wanda Maximoff, I’m gonna go into cardiac arrest” (ThePressFree, August 26, 2021). Fan edits and videos, like those shared by @gxthicrogue, tease the spectacle of Phoenix’s fiery energy clashing with Wanda’s crimson chaos (ThePressFree, August 26, 2021). Reddit’s r/MCUTheories speculated that Doomsday could feature a “Phoenix v Scarlet Witch showdown,” with some users arguing Jean’s inclusion is vital, or she should be “written off” (Reddit, March 27, 2025). However, concerns linger that Jean, like Professor X in Multiverse of Madness, might face a “brief cameo before a horrible death” (Reddit, March 27, 2025).
The narrative fit is compelling. Doomsday centers on Doctor Doom, played by Downey, whose multiversal schemes could draw in variants like Jean from Fox’s X-Men universe (ScreenRant, April 14, 2025). Wanda, if she returns, might confront Doom after surviving Multiverse of Madness, with GeekTyrant suggesting she could be Doom’s ally or lover (GeekTyrant, November 8, 2024). A Jean-Wanda clash could serve as a climactic moment, pitting two women with reality-altering powers against each other, possibly orchestrated by Doom to destabilize the multiverse (Reddit, March 27, 2025).
The X-Men in the MCU: A Farewell or a Rebirth?
Janssen’s rumored return aligns with the MCU’s integration of Fox’s X-Men, following Disney’s 2019 acquisition of 20th Century Fox (ScreenRant, December 23, 2023). Patrick Stewart (Professor X), Hugh Jackman (Wolverine), and Kelsey Grammer (Beast) have reprised their roles in Multiverse of Madness and Deadpool & Wolverine, signaling a farewell to Fox’s universe (ComicBook, April 24, 2024). CBR noted that Doomsday may “bid farewell” to Fox’s X-Men, with Marsden’s Cyclops confirmed and speculation about Halle Berry (Storm) and Anna Paquin (Rogue) (CBR, April 4, 2025; Reddit, March 27, 2025). Reddit users predict Doomsday and Secret Wars will serve as a “send-off” for original X-Men actors, paving the way for a rebooted X-Men team led by younger mutants or James McAvoy’s cast (Reddit, March 27, 2025).
Janssen has expressed openness to returning, telling ComicBook in 2024, “You never know,” while citing Jean’s history of resurrections (ComicBook, April 24, 2024). In a 2021 Observer interview, she noted she’d be “very open” to reprising Jean if Marvel called, referencing Days of Future Past’s surprise returns (ThePressFree, August 26, 2021). However, SlashFilm warned that Doomsday might repeat Multiverse of Madness’s mistake of killing off legacy X-Men like Xavier, risking fan alienation (SlashFilm, April 2, 2025). The rumor of Janssen’s role, if true, could mean a significant part or a fleeting cameo, with fans on X like @GFRobot hoping for an “epic shot” of the original X-Men (X, December 29, 2022).
Wanda Maximoff’s Uncertain Return
The rumored Jean-Wanda showdown hinges on Wanda’s survival after Multiverse of Madness, where she seemingly died destroying the Darkhold (SuperHeroHype, January 7, 2025). GeekTyrant and Beyond The Trailer reported that Olsen’s Earth-616 Wanda could return in Doomsday, potentially as a major player alongside Downey’s Doom (GeekTyrant, November 8, 2024). However, Olsen’s March 2025 statement that she’s not returning for Doomsday or Secret Wars casts doubt, though she left room for future involvement (ComicBookMovie, March 25, 2025). IMDb and SuperHeroHype suggest her return is likely, given Wanda’s multiversal significance and fan demand (IMDb, September 25, 2024; SuperHeroHype, January 7, 2025).
Wanda’s Chaos Magic, enhanced by the Darkhold, makes her a formidable foe for Jean’s Phoenix Force, with LiveAkhbar noting her reality-warping could challenge Jean’s raw power (LiveAkhbar, November 22, 2022). Reddit’s r/marvelstudios debated whether Wanda and Jean’s absence from Doomsday stems from their overpowering abilities, which could overshadow Doom’s threat (Reddit, April 4, 2025). If both return, their clash could be a narrative necessity to balance their godlike powers, possibly orchestrated by Doom to weaken Earth’s defenses (Reddit, March 27, 2025).
Fan Reactions: Hype, Hope, and Hesitation
The fandom is electrified but divided. X posts like @sociedadexmen’s “Famke Janssen retorna como JEAN GREY/PHOENIX” and @Austin_Medzz’s claim of her MCU return have amassed likes, with fans sharing edits of Jean’s fiery Phoenix aura clashing with Wanda’s crimson magic (X, March 28, 2025; X, March 31, 2025). Reddit’s r/MCUTheories hyped the “Phoenix v Scarlet Witch showdown” as a must-have, with users like u/Flashy-Ad9129 predicting a multiversal spectacle (Reddit, March 27, 2025). Some fans, however, fear a repeat of Multiverse of Madness, where legacy characters were killed off, with one user stating, “Doom will probably kill Jean like Wanda killed Xavier” (Reddit, March 27, 2025).
Skeptics question the rumor’s credibility, citing Olsen’s denial and the absence of Marvel’s confirmation (ComicBookMovie, March 25, 2025). X user @SkepticFan123 called it “fan fiction,” while r/marvelstudios users debated whether Sophie Turner or Sadie Sink might play Jean instead, given Janssen’s age (60) versus the reboot’s younger focus (Reddit, April 4, 2025). The Adam Driver meme backlash against Essiedu’s Snape casting shows how fan expectations can fuel toxicity, raising concerns about similar reactions if Jean’s role disappoints (Newsweek, April 15, 2025).
The Multiverse Saga’s High Stakes
Avengers: Doomsday, with a $250 million budget, is a pivotal chapter in the MCU’s Multiverse Saga, directed by the Russo Brothers and featuring Downey’s Doctor Doom as a multiversal tyrant (GamesRadar, March 22, 2025). The confirmed cast, including Cumberbatch, Marsden, and Thunderbolts stars like Sebastian Stan and Florence Pugh, suggests a sprawling ensemble, with The Hollywood Reporter hinting at more reveals (The Hollywood Reporter, April 2025). Secret Wars will follow in 2027, potentially resetting the MCU with new X-Men and Avengers teams (Reddit, March 27, 2025).
The rumored Jean-Wanda clash fits the multiverse’s chaotic scope, with ScreenRant noting that Doomsday could explore Doom’s manipulation of variants like Jean to destabilize realities (ScreenRant, March 20, 2025). However, Multiverse of Madness’s violent treatment of the Illuminati—Xavier’s neck snapped by Wanda—raises fears that Jean might suffer a similar fate (SlashFilm, April 2, 2025). CBR highlighted Janssen’s absence from the initial Doomsday cast announcement as a “missed opportunity,” fueling hope for a surprise reveal (CBR, April 4, 2025).
The Industry Context: Diversity and Legacy
The Harry Potter reboot’s backlash against Paapa Essiedu’s Black Snape shows how diverse casting can spark toxicity, a risk Marvel must navigate with X-Men integration (Newsweek, April 15, 2025). Janssen’s return, as a white actress reprising a legacy role, avoids such controversy but faces scrutiny over age and narrative fit. Snow White’s 2025 flop ($145 million vs. $270 million) and Tangled’s pause over diverse casting highlight the industry’s sensitivity to fan reactions, suggesting Marvel will tread carefully (Variety, April 2025). A 2021 UCLA Hollywood Diversity Report noted that diverse castings trigger disproportionate abuse, a lesson Marvel may apply to protect its cast (Newsweek, April 2025).
Janssen’s openness to return, contrasted with Olsen’s uncertainty, underscores the delicate balance of legacy and innovation. The Independent noted that fan campaigns, like those for Spider-Man: No Way Home, can influence casting, suggesting X buzz could pressure Marvel to include Janssen (The Independent, March 2025). If confirmed, her role could be a cameo or a major part, with Reddit users hoping for an “original X-Men” moment akin to No Way Home’s Spider-Men (Reddit, March 27, 2025).
A Cosmic Clash or Wishful Thinking?
The rumor of Famke Janssen returning as Jean Grey to face Wanda Maximoff in Avengers: Doomsday is a thrilling prospect, blending nostalgia with multiversal stakes. The Phoenix-Scarlet Witch showdown, fueled by fan edits and X hype, promises a spectacle, but unverified claims and Olsen’s denial cast doubt. As Doomsday approaches, with filming starting March 2025, Marvel’s silence keeps the rumor speculative (SuperHeroHype, January 7, 2025). Whether Jean rises or remains a fan dream, the buzz proves Harry Potter and X-Men’s enduring power to spark passion and debate. This clash, if realized, could light up the multiverse—or burn out in rumor’s ashes.
