The MCU has charged into the Multiverse Saga, and now all the cosmic gears are lining up for what looks like its biggest event yet: Avengers: Doomsday. According to official sources, the film sees the Avengers, Wakandans, Fantastic Four, New Avengers—and even the “original” X-Men—joining forces against Doctor Doom. 

But with such a massive roster already, one of the most exciting questions is: which key heroes have not been confirmed yet? And which ones matter most to the story, to us emotionally, and to the multiversal stakes?

I’ve ranked ten of the biggest “missing” heroes—from least to most important—and why their inclusion (or absence) would resonate in deep ways.

10. Star‑Lord / Peter Quill

Why we want him: At the end of Guardians of the Galaxy Vol. 3, Peter Quill returns to Earth, hinting “The Legendary Star-Lord Will Return.” His blend of cosmic swagger and human vulnerability makes him a compelling bridge between Earthbound Avengers and the wider cosmos.

What he brings: Quill has seen galaxy-spanning threats, he’s got the heart (he’s lost friends, made mistakes), and he’s familiar with feeling out of step—a great mirror to multiversal chaos. He can show up, crack jokes, connect emotionally, and remind us that even cosmic heroes can be messy.

The missing piece: If he doesn’t show up, it feels like a gap in the “cosmic to earth” arc—especially for a movie that promises to span realities.

9. Captain Marvel / Carol Danvers

Why we want her: Carol’s one of the heaviest hitters in the MCU. Her power set is cosmic, her knowledge is deep, and after The Marvels, she has personal stakes (especially through her relationship with Monica Rambeau). If there’s a universe-level threat, Carol’s absence would leave a big hole.

What she brings: Leadership, cosmic awareness, and a different vantage than earthbound Avengers. Her presence could unify the massive scale of Doomsday with characters who live beyond Earth-616.

The emotional layer: Her connection to Monica adds depth. If they bring Monica in (see below) and Carol’s absent or sidelined, it might undercut that relationship. If Carol is in, you get heroics plus kitchen-table stakes.

8. Kate Bishop (Hawkeye)

Why we want her: She represents the next generation. While the big cosmic threats dominate, there’s always room (and emotional need) for characters who ground the story, who show us how ordinary-heroic evolves into legendary-heroic. Kate Bishop fits that role.

What she brings: Archery skills, heart, a lighter touch—but still gravitas. Especially if Doomsday leans very heavy cosmic/multiversal, Kate provides a human anchor, reminding us: heroes don’t need to wield infinity stones to matter.

Narrative opportunity: Her earlier teaming with Ms. Marvel hinted at youth-driven hero teams (Young Avengers). Including her could set up the MCU’s next generation within the event.

7. Scarlet Witch / Wanda Maximoff

Why we want her: Wanda’s arc has been one of the most human, raw, emotionally intense in the MCU. Her magic connects to the multiverse. Her loss, guilt, power—she’s perfectly positioned for a story about unraveling realities.

What she brings: Mystical power, emotional weight, redemption potential. And if the multiverse is unraveling, the person whose story is unraveling—Wanda—makes so much sense to put front-and-center.

Why her absence would sting: Leaving Wanda out would feel like leaving a major piece of the multiversal puzzle unreconciled. Her personal story intersects with chaos magic, other universes, loss and hope.

6. Hulk / Bruce Banner / Hulk

Why we want him: Bruce Banner (and Hulk) is more than a smash-jumper. He’s a scientist, an Avenger founder, a character who bridges raw power and intellect. For a crisis of realities, you want both.

What he brings: Strength and brain. Emotional history (loss, regret, identity). The Hulk’s very existence has always been about inner and outer battles—so he maps well to a cosmic external threat with internal echoes.

What we’re worried about: He hasn’t had major screen time in a large-scale conflict lately. His return could signify that the MCU is re-engaging older founding heroes with newer stakes.

5. Moon Knight / Marc Spector

Why we want him: Moon Knight occupies a strange, lesser-used niche: supernatural, psychological, mystical. The MCU has teased gods, magic, alternate realities. Bringing Moon Knight gives the strange, the “other”, the edge.

What he brings: A character layered in identity, pain, faith, mysticism. He isn’t just another hero with power—he’s someone haunted by his power, used by a god, wrestling with self. That’s rich fodder in a story about the multiverse collapsing, identities shifting, realities dying.

Narrative benefit: He could bring a tone-shift into the film—less purely cosmic blockbuster and more… weird, immersive, layered. His inclusion signals that Avengers events don’t always need bright banners and skyscraper fights—they can delve into internal mythologies.

4. Wolverine / Logan

Why we want him: Wolverine is more than a cameo-whack. He’s a living legend in the mutant world, one with lived history, scars, redemption paths, a disappearing cage. Bringing him into Doomsday bridges the X-Men world and the mainline Avengers world in a major way.

What he brings: Raw ferocity, deep legacy, moral complexity, experience that spans decades—even centuries. In a story where the multiverse is expanding, fracturing, creating alternate versions—Logan has seen a lot. He can be both stabiliser and wildcard.

Why his inclusion matters: The film already hints at X-Men involvement. Wolverine would be a key bridge to that thread. If he’s missing, the mutants’ part of the story might feel less tied to the emotional core.

3. Spider‑Man / Peter Parker

Why we want him: Spider-Man is a pillar of the MCU’s emotional heart. He’s the youth, the “every-kid” elevated, the underdog who rises. His experience with multiverse hijinks (thanks to No Way Home) gives him a credible doorway into the chaos.

What he brings: Relatability, humanity, stakes born of love and loss. He can ground enormous threats. He also serves as an audience proxy: while gods and cosmic guys fight, Spidey reminds us what being human means.

What his absence might signal: It would feel weird for the MCU’s flagship “friendly neighbourhood” hero to skip a mega event of this scale. It would raise questions: is this a “grown-up Avengers” event that leaves out younger heroes? Or is Peter Parker just busy elsewhere?

2. Monica Rambeau / Photon

Why we want her: Monica stepped into the multiverse via The Marvels, waking in a reality connected to the X-Men universe. That puts her at the crux of the Earth-616/X-Men/Multiverse boundary. Her story is already about being lost, powerful, transformed.

What she brings: She is both meta-symbol and narrative connector. For Doomsday, which seems to bring together Avengers + mutants + alternate realities, Monica could be the bridge. Her powers (Photon) give unique visual and thematic potential.

Emotional layer: She’s less about flashy heroics (though powerful) and more about identity, connection, transformation. In a story threatened by realities collapsing, someone who fell between realities has immeasurable resonance.

1. Doctor Strange / Stephen Strange

*Why he is the most important of the unconfirmed heroes.
Doctor Strange is the architect of multiversal awareness in the MCU. He’s dealt with incursions, alternate realities, chaos magic, multiverse collapse. For a film titled “Doomsday” that promises multiversal stakes—Strange is the specialist, the lens through which we understand what’s happening.

What he brings: Expertise, leadership, mystic depth. He can explain, intervene, act as the anchor for “why this matters.” Without Strange, the multiversal core of the story might drift into spectacle without meaning.

Narrative risk if missing: If Strange is absent or sidelined, the story could risk feeling disconnected or incomplete. The multiverse arc that he has front-and-center might lack a character who has lived it, understands it, carries its scars. It would be like staging a space war without the astronaut.

Extra weight: Many rumors suggest his role is still unconfirmed or indirectly referenced. His inclusion would signify that Marvel takes the multiverse threat seriously—and wants the audience to feel the weight of it.

As the Multiverse Saga edges closer to its breaking point, Avengers: Doomsday feels less like another MCU event and more like the moment everything converges — legacies, timelines, worlds, and every unresolved story thread the franchise has been weaving for years. The heroes we’ve discussed aren’t just “missing roster slots”; they’re emotional anchors, cosmic experts, mystical outliers, and future icons whose presence could transform Doomsday from a blockbuster into a cultural earthquake.

Whether they return or not, one thing is clear: this film is about the past colliding with the future. Redemption arcs, multiversal consequences, fractured identities, collapsing timelines — the MCU has set the table for a narrative that demands the return of its most defining heroes.
