Fan Theories and Predictions Fueling the Multiverse Saga’s Next Phase

In the ever-expanding tapestry of the Marvel Cinematic Universe (MCU), fan theories have evolved from mere speculation into a cultural phenomenon, often presciently mirroring the seismic shifts in comic book lore. As Marvel Studios charts its course post-Endgame with the Multiverse Saga, enthusiasts pore over trailers, casting announcements, and comic precedents to craft narratives that could redefine heroes and villains alike. These predictions, rooted in decades of Marvel comics, blend Easter eggs, narrative breadcrumbs, and wild extrapolations, keeping the fandom pulse racing ahead of official reveals.

What makes these theories compelling is their foundation in Marvel’s rich comic history. From the cosmic incursions of Hickman’s Avengers to the devilish machinations of Doctor Doom, fans draw direct lines between page and screen. This article delves into the most tantalising fan speculations for upcoming films like Fantastic Four: First Steps, Thunderbolts, Blade, Avengers: Doomsday, and Avengers: Secret Wars, analysing their comic origins, plausibility, and potential impact on the MCU’s trajectory.

With directors like the Russo brothers returning for the Avengers epics and fresh visions from Matt Shakman and Jake Schreier, the stakes feel operatic. Will these movies honour comic fidelity, or twist canon for cinematic spectacle? Fans believe the answers lie in overlooked panels and long-dormant arcs, promising revelations that could eclipse even the Infinity Saga’s grandeur.

Fantastic Four: First Steps – A Cosmic Family Reunion?

The heralded return of Marvel’s First Family in 2025’s Fantastic Four: First Steps, directed by Matt Shakman, has ignited theories centring on their Earth-616 comic roots transposed into the MCU multiverse. Starring Pedro Pascal as Reed Richards, Vanessa Kirby as Sue Storm, Joseph Quinn as Johnny Storm, and Ebon Moss-Bachrach as Ben Grimm, the film promises a retro-futuristic vibe echoing Jack Kirby’s original designs.

One dominant theory posits that the Fantastic Four hail from an alternate universe ravaged by Galactus, forcing a multiverse-hopping incursion that dovetails with Secret Wars. Comic fans point to Jonathan Hickman’s 2011-2012 FF and Avengers runs, where Reed orchestrates the Illuminati’s desperate measures against the Great Eater. Online forums buzz with predictions that Julia Garner’s Silver Surfer will serve as herald, not villain, guiding the team to Doctor Doom’s Latverian stronghold – a nod to Stan Lee and Kirby’s 1961 debut where Doom debuts as their arch-nemesis.

Another fervent speculation involves Franklin Richards, Reed and Sue’s reality-warping son, manifesting as a young mutant whose powers accidentally trigger the film’s incursion. Drawing from Chris Claremont’s Fantastic Four issues in the 1980s and Mark Millar’s Ultimatum fallout, fans predict Franklin’s emergence bridges the X-Men into the fray, especially with mutant teases in Deadpool & Wolverine. Plausibility soars given Pascal’s comments on family dynamics; if realised, this sets up a Richards-Doctor Doom rivalry laced with tragic brotherhood from Books of Doom (2005).

  • Galactus as World-Eater Supreme: Not a cloud, but Ralph Ineson voicing a Kirby-esque colossus devouring timelines, per Earth X influences.
  • Doom’s Early Shadow: Robert Downey Jr. rumoured as Doom via multiverse variant, subverting his Iron Man legacy from Brian Michael Bendis’s New Avengers.
  • Nova Corps Cameo: Paving for Richard Rider’s solo film, echoing the Kree-Skrull War’s cosmic stakes.

These theories elevate the film beyond origin retread, positioning the FF as multiverse architects whose comic legacy – over 600 issues of innovation and heartbreak – demands a pivotal role.

Thunderbolts – Anti-Heroes or Secret Society?

Slated for 2025 under Jake Schreier’s helm, Thunderbolts assembles MCU’s black-ops misfits: Florence Pugh’s Yelena Belova, Sebastian Stan’s Bucky Barnes, David Harbour’s Red Guardian, Olga Kurylenko’s Taskmaster, and Wyatt Russell’s U.S. Agent. Fans theorise this isn’t a straightforward Suicide Squad analogue but a covert Illuminati offshoot, pulling from Fabian Nicieza’s 1997 Thunderbolts #1 bombshell where the team reveals as Baron Zemo’s Masters of Evil.

The prevailing prediction: Valentina Allegra de Fontaine (Julia Louis-Dreyfus) as the puppet-master, engineering the squad to hunt multiversal incursions while concealing her ties to the High Evolutionary or even Mephisto. Comic parallels abound in Kurt Busiek’s run, where Thunderbolts grapple with redemption amid betrayal. Enthusiasts dissect The Falcon and the Winter Soldier‘s Flagsmashers echo to predict a Zemo cameo (Daniel Brühl), manipulating from the shadows as in Ed Brubaker’s Winter Soldier arcs.

Key Wild Cards in Fan Speculation

Deeper dives reveal layered predictions:

  1. Sentry’s Introduction: Lewis Pullman as Robert Reynolds, whose Void persona unleashes chaos, mirroring Paul Jenkins’s 2000 miniseries and tying to Hulk’s World War Hulk rage.
  2. Ghost Rider Tease: Robbie Reyes variant via multiverse, avenging fallen Thunderbolts in Robbie Baldwin’s Dark Avengers style.
  3. Contessa’s Endgame: Valentina exposed as a Skrull or Dormammu agent, subverting the team’s heroic pivot from Charles Soule’s 2013 series.

If these pan out, Thunderbolts becomes the saga’s moral grey zone, contrasting Avengers’ purity with comic Thunderbolts’ theme of flawed redemption.

Blade – Daywalker’s Demonic Reckoning

Mahershala Ali’s long-awaited Blade, now eyeing 2025 amid reshoots, stirs theories of a Marvel Knights horror pivot. Fans invoke Marv Wolfman and Gene Colan’s 1970s Tomb of Dracula run, predicting Blade mentors a new trio: Lilith Drake (his daughter from 1990s comics), Morbius (post-No Way Home), and Elsa Bloodstone, forming a Midnight Sons precursor.

A scorching theory claims Snipes’ original Blade appears as a multiverse variant, clashing in a father-son duel echoing Blade: Trinity tensions but amplified by Dante’s Inferno-inspired hell dimensions from Daniel Knauf’s 2006 series. With Mia Goth as Lilith, speculation mounts for a vampire civil war, where Blade uncovers Dracula’s resurrection – a staple from Frank Miller’s Elektra crossovers.

  • Mephisto’s Strings: As the saga’s devil (teased in WandaVision), bartering souls per J.M. DeMatteis’s Marvel Zombies.
  • Blade’s Hybrid Origin: Half-vampire physiology granting Daywalker powers via ancient Bloodgem, from 1998’s Blade vol. 2.
  • X-Men Link: Wolverine cameo hunting vampires, nodding to their Curse of the Mutants alliance.

This film could anchor Marvel’s supernatural corner, reclaiming Blade’s comic grit amid MCU polish.

Avengers: Doomsday – Doom’s Multiversal Gambit

The Russo brothers’ Avengers: Doomsday (2026) swaps Kang for Doctor Doom, fuelling epic predictions. RDJ’s casting screams variant Iron Man turned Latverian tyrant, per Hickman’s Avengers where Doom steals Beyonders’ power. Fans foresee an incursion-ravaged Earth, with Doom allying Doctor Strange and Reed against Galactus, only to betray for godhood as in Secret Wars (2015).

Theories highlight Illuminati reformation: Strange, Reed, Black Panther, Maria Hill analogue, echoing Brian Bendis’s 2000s blueprint. Loki’s TVA remnants expose Doom’s Council of Reeds plot from Matt Fraction’s FF.

Avengers: Secret Wars – Battleworld’s Apocalypse

Culminating in 2027, Secret Wars promises comic cataclysm. Predictions centre on Battleworld mosaic: domains ruled by Doom, with heroes scraping from House of M-style remnants. God Emperor Doom (RDJ) vs. Avengers, Molecule Man as wildcard from Jonathan Hickman’s opus.

  • Spider-Man Saves All: Miles Morales bridging universes, per Spider-Verse comics.
  • X-Men Invasion: Krakoa fall unleashing Orchis, from Kieron Gillen’s runs.
  • Cosmic Reform: Beyonders slain, birthing MCU 4.0 with mutants integrated.

Conclusion

Fan theories for Marvel’s horizon aren’t idle chatter; they’re a testament to comics’ enduring blueprint, where Hickman, Kirby, and Wolfman laid multiversal foundations now blooming on screen. Whether Doom usurps as god-king, Thunderbolts shatter trust, or Blade ignites supernatural fury, these predictions underscore Marvel’s genius: inviting fans to co-author the mythos. As Secret Wars looms, expect mind-bending payoffs that honour the page while forging new legends. The multiverse awaits – what twists will you predict?
