Kathryn Hahn drops a cryptic hint about Agatha Harkness in Doomsday! She’s eyeing the Avengers—ghost witch vs. Doom? Hype’s real! [link] #MCU #AgathaAllAlong #Doomsday

Kathryn Hahn’s Agatha Harkness has cast a spell over the Marvel Cinematic Universe, and she might not be done yet. A March 9, 2025, ScreenRant piece (reimagined here) captures Hahn dropping a tantalizing hint at SXSW about her witchy antihero’s potential role in Avengers: Doomsday (May 2026) and Secret Wars (May 2027). After stealing WandaVision (2021) and leading Agatha All Along (2024) to critical acclaim—79% on Rotten Tomatoes—Hahn’s ghost-witch ended her solo series mentoring Billy Maximoff (Joe Locke), only to leave fans craving more. Now, with the Multiverse Saga barreling toward its climax, Hahn’s coy tease—caught on THR’s red carpet—suggests Agatha could hex her way into the Avengers’ next fight. As of 8:26 PM PDT, March 9, 2025, Phase Five’s wobbling, and Doomsday’s filming looms—could Agatha be the supernatural spark to reignite the MCU? Let’s break down the hint, the odds, and the fan frenzy.

From Westview to the Multiverse

Agatha’s MCU arc is a rollercoaster. WandaVision unveiled her as Wanda Maximoff’s (Elizabeth Olsen) cackling nemesis—a centuries-old witch posing as nosy neighbor Agnes, undone by Wanda’s Scarlet Witch awakening. Trapped as Agnes, her story seemed sealed—until Agatha All Along broke her free. The Disney+ hit saw Agatha, powerless post-Wanda, trek the Witches’ Road with a ragtag coven, only to sacrifice herself to Death (Aubrey Plaza) and return as a ghost guiding Billy, Wanda’s reincarnated son. It’s a redemption arc wrapped in campy chaos—Hahn’s Emmy-nominated turn earned raves—and the finale’s open-ended exit with Billy hunting Tommy Maximoff screamed “sequel bait.”

Enter SXSW 2025. THR nabbed Hahn on the red carpet, asking if Agatha’s in Doomsday, set to start shooting soon. Her response? A sly, “I don’t know… but I’d play her forever if I could.” ScreenRant’s take: it’s no denial—more a tease that’s got fans buzzing. Posts on X erupt—“Agatha vs. Doom? Take my money!”—while others hedge, “She’d steal the show.” After Agatha All Along’s success—Kevin Feige called it “great for us” (ScreenRant, 2024)—Hahn’s hint feels deliberate. She’s not spilling, but she’s not shutting it down either. With Doomsday and Secret Wars poised to cap the Multiverse Saga, Agatha’s ghost could be more than a cameo.

Why Doomsday Fits

Doomsday’s the Russo Brothers’ return—RDJ as Doctor Doom, a roster of Fantastic Four, Strange, Spider-Man, mutants (GamingBible, March 6). Leaked art (GamingBible, March 4) paints Doom as a medieval tyrant ruling Battleworld—perfect for a witchy wildcard. Agatha’s comics roots tie her to chaos—she’s mentored Scarlet Witch, tangled with cosmic forces (Avengers #128). As a ghost, she’s invulnerable, per Agatha All Along’s finale—banishable, sure, but a spell-slinger like Doom wouldn’t flinch. ScreenRant’s op-ed might argue she’s the supernatural edge Doomsday needs—hexing Doom’s multiversal schemes, guiding Billy (a Young Avengers lock) against Strange’s corruption.

Her WandaVision ties help. Wanda’s Hex warped reality; Billy’s Witches’ Road did too. Doomsday’s multiversal mash-up—Doom vs. Loki’s TVA (GamingBible, March 6)—could use Agatha’s reality-bending know-how. Hahn’s tease—“forever if I could”—nods to her love for the role, and Feige’s praise suggests Marvel’s listening. X fans speculate: “Ghost Agatha whispering to Billy while Doom rants? Iconic.” Doomsday’s chaos—medieval vibes, mutant influx—screams for a witch who’s danced with Death herself. Plus, Hahn’s What If…? Season 3 gig (December 2024) as a musical Agatha variant proves she’s still in the game.

Secret Wars and Beyond

If not Doomsday, Secret Wars—2027’s saga-ender—ups the ante. Comics Secret Wars (2015) saw Doom forge Battleworld; Agatha’s ghost could haunt its ruins, aiding heroes or twisting fates. Agatha All Along set her as Billy’s mentor—echoing her comics role with Wanda—and Secret Wars’s reset (GamingBible, March 6) might resurrect her. A Young Avengers arc looms—Kamala Khan (Iman Vellani) recruited Kate Bishop (The Marvels, 2023); Billy’s next. Agatha whispering in his ear fits Hahn’s “side-door” MCU love (Rolling Stone, 2024)—not center stage, but pivotal.

Phase Six needs her too. Spider-Man 4 (GamingBible, March 7) hits November 2026—street-level, sure, but post-Doomsday multiverse ripples could pull her in. Vision Quest (2026) ties to Wanda’s kids—Agatha’s a natural fit. ScreenRant’s take: her ghost state’s a cheat code—untouchable, unbound, a witchy Yoda for a new MCU. Hahn’s SXSW dodge—“I don’t know”—feels like Marvel’s classic coyness; Feige’s “more Agatha” vow (ScreenRant, 2021) backs it. X posts dream big: “Agatha resurrecting Wanda for Secret Wars? Chills.”

Fan Split: Hype vs. Doubt

Fans are torn—X lights up with it. “Agatha in Doomsday would slay,” one raves; “Too crowded already,” another snipes. Doomsday’s roster—FF, Strange, Hulk (ScreenRant, March 9)—risks bloat; Hahn’s scene-stealing chops could unbalance it. Agatha All Along’s 79% trumps The Marvels’s 62%, but Phase Five’s flops (Quantumania’s 47%) spook skeptics—“Another cameo fest?” Deadpool & Wolverine’s $1.3 billion (2024) proves fans love chaos, though—Agatha fits that vibe.

Optimists see gold. “Hahn’s chemistry with Locke? Secret Wars needs that,” an X user insists. Her ghost form—practical, per Agatha All Along’s Mary Livanos (ScreenRant, 2024)—sidesteps power creep; she’s a guide, not a god. Brave New World’s mutant tease (February 2025) aligns with her X-Men comics ties (Fantastic Four #94). Doubt lingers—Hahn’s “goodbye” to Agatha (LA Times, 2024) worried some—but her SXSW pivot—“forever if I could”—flips the script. Fans bet on Marvel’s long game.

Marvel’s Move: Risk and Reward

Why tease now? Doomsday filming nears—March 2025 buzz (ScreenRant, March 8)—and Hahn’s hint stokes hype. Thunderbolts* (May 2025) and Fantastic Four (July 2025) build to it; Agatha’s a bridge—supernatural spice in a tech-heavy saga. Risk? Overstuffing—Doomsday’s $200 million-plus budget (Forbes, March 8) can’t falter. Reward? Hahn’s a draw—WandaVision’s 92% set her up; Agatha sealed it. Feige’s “no reboot” post-Secret Wars (GamingBible, March 6) means Agatha’s ghost could linger—Phase Seven’s mentor, not a one-off.

Her fit’s logical—Doom’s magic-tech hybrid (Doctor Strange #18) meets Agatha’s chaos magic. What If…?’s musical Agatha (December 2024) tests variants—Doomsday could too. Hahn’s “I don’t know” isn’t a no—it’s a Russo-style dodge (Infinity War leaks, anyone?). X theorizes: “Agatha banishing Doom’s army—ghost OP.”

The Verdict: A Witchy Wildcard

Kathryn Hahn’s SXSW tease—via ScreenRant—lights a fuse. Agatha Harkness in Doomsday or Secret Wars isn’t confirmed, but it’s not crazy. Her ghost form, Billy tie, and Hahn’s passion—“forever if I could”—scream potential. Doomsday’s multiversal war needs her edge; Secret Wars’s reset could crown her. Phase Five’s stumbles—The Marvels, Quantumania—crave a win; Hahn’s witch delivers.

Fans split—hype soars, doubts nag—but the MCU thrives on bold swings. Deadpool worked; Agatha could too. X’s “#AgathaHarkness” trends—hope’s alive. Hahn’s coyness, Feige’s praise, and Doomsday’s stakes align—Agatha’s haunting the multiverse, one way or another. Stay tuned—this witch ain’t done casting.
