Marvel moved away from Kang and toward Robert Downey Jr.’s Doctor Doom earlier than many fans realized. According to Kevin Feige, the studio had already started questioning whether Kang could function as the Multiverse Saga’s true Thanos-level threat around the time Ant-Man and the Wasp: Quantumania was arriving, and conversations about Doctor Doom had already begun before Marvel officially pivoted away from Kang. That shift eventually reshaped Avengers: The Kang Dynasty into Avengers: Doomsday, positioned Doom as the new centerpiece villain, and turned one of the MCU’s biggest long-range plans into a major course correction.
Kevin Feige quote on Marvel moving away from Kang
Kevin Feige’s clearest public explanation came in a 2025 interview in which he said Marvel had started to realize “Kang wasn’t big enough” and “wasn’t Thanos,” while also explaining that discussions about Doctor Doom had begun even before the official pivot away from Kang. Search snippets from that interview show Feige framing the move not as a last-second emergency rewrite, but as a realization that Doom was better suited to be the defining multiverse-scale villain.
That matters because it reframes the narrative. For months, the common assumption was that Marvel abandoned Kang only because Jonathan Majors’ legal case forced the studio’s hand. Feige’s account suggests the legal fallout accelerated a change that was already being seriously considered inside Marvel. Public reporting from late 2023 also showed executives discussing backup plans, including a possible pivot to Doctor Doom, before the final break with Majors was announced.
When Marvel started shifting from Kang to Doctor Doom
By Feige’s own timeline, Marvel started shifting from Kang to Doom around the Quantumania period in early 2023, or even slightly before the film’s release. In his telling, the studio was already reassessing Kang’s ceiling as the Multiverse Saga’s top villain and had begun talks with Robert Downey Jr. about a radically different MCU return as Victor von Doom.
That timing is significant because Quantumania was designed to sell Kang as the next grand MCU threat. Instead, the film ended with Kang defeated in a way that made him feel vulnerable rather than inevitable, and audience momentum around the character never fully reached Thanos-level intensity. Feige’s later comments imply Marvel could already see that problem while the saga was still being built.

Ant-Man and the Wasp: Quantumania Kang ending explained
At the end of Ant-Man and the Wasp: Quantumania, Kang the Conqueror is apparently defeated after being dragged into his own multiversal engine during the battle in the Quantum Realm, while the film’s post-credits material expands the threat by revealing the Council of Kangs. The intended message was that even if one Kang fell, countless variants remained.
On paper, that setup should have elevated the danger. In practice, it produced the opposite effect for many viewers. The version of Kang who was supposed to feel uniquely terrifying lost in his first full-feature spotlight, which undercut the character’s aura. That is why Feige’s later “wasn’t Thanos” framing lands so hard: Quantumania tried to crown Kang, but the ending left Marvel with a villain who felt conceptually important without yet feeling cinematically dominant.
Why Kang “wasn’t Thanos” for the MCU (Feige’s reasoning)
Feige’s reasoning appears to come down to scale, clarity, and comic-book status. His public comments point to Marvel deciding that Kang did not land as the singular, definitive saga villain in the way Thanos did, and that Doctor Doom was the one character with decades of comic history and enough mythic weight to fill that role.
Thanos worked because Marvel built him as a steadily escalating, unmistakable endgame threat. Kang, by contrast, arrived through variants, time loops, multiverse branching, and multiple incarnations with different power levels and agendas. That complexity is part of the character’s comic appeal, but it also makes him harder to center as a clean, mainstream blockbuster villain. Doom is more legible: ruler, scientist, sorcerer, tyrant, and archrival with a stronger brand identity for general audiences. That likely made him more appealing once Marvel decided it needed a more immediately commanding Multiverse Saga antagonist.
Jonathan Majors legal issues and the MCU Kang fallout
Jonathan Majors’ legal case became the turning point in public. In December 2023, Majors was convicted of one misdemeanor assault charge and one harassment violation related to an incident involving his former girlfriend, and Marvel and Disney dropped him the same day. That immediately threw the future of Kang-led MCU planning into doubt.
Even if Marvel had already begun reevaluating Kang creatively, the Majors verdict transformed that internal debate into an unavoidable business decision. A saga built around a recurring face becomes much harder to sustain when the actor is removed after a conviction. The result was not just a casting problem but a structural storytelling problem, because Kang had already been woven into Loki, Quantumania, and the then-announced Avengers: The Kang Dynasty.

Did Marvel consider recasting Kang the Conqueror?
Public reporting indicates Marvel discussed alternatives while Kang’s future was in doubt, but the studio ultimately chose not to solve the problem with a straightforward recast. A late-2023 Variety report said executives were discussing backup plans that included pivoting to another villain such as Doctor Doom. In 2025, Variety also reported that Marvel decided not to recast Kang and instead overhauled its story plans around Doom.
So the most accurate answer is that Marvel appears to have weighed multiple paths, but the public evidence points toward a strategic pivot rather than a clean actor replacement. That distinction matters. Recasting Kang would have preserved the larger blueprint. Replacing Kang with Doom meant rewriting the blueprint itself.
Robert Downey Jr as Doctor Doom: what’s confirmed so far
What is confirmed is substantial. At San Diego Comic-Con 2024, Marvel officially revealed that Robert Downey Jr. would return to the MCU as Doctor Doom, not Iron Man. Marvel’s own Hall H recap quotes Downey saying, “New mask, same task,” while confirming he will play Victor von Doom in the upcoming Avengers films.
Marvel’s official movie pages now list Robert Downey Jr. as cast in both Avengers: Doomsday and Avengers: Secret Wars. The current Marvel.com listings give Doomsday a release date of December 18, 2026, and Secret Wars a release date of December 17, 2027. Marvel’s official Doomsday trailer page also explicitly identifies Doctor Doom as Victor von Doom.
By 2026, Doom has also been teased onscreen beyond the Hall H reveal. Reporting around The Fantastic Four: First Steps and Avengers: Doomsday indicates that Downey’s Doom was teased in Fantastic Four’s credits scene and then shown more directly in Doomsday footage.
Doctor Doom vs Kang: who works better as the Multiverse Saga villain
Doctor Doom works better than Kang as the Multiverse Saga villain if the goal is to give the saga one central face, one central ideology, and one central power fantasy. Doom is easier to market, easier to dramatize, and easier to elevate into a crossover event villain because he combines political power, scientific genius, mystical ambition, and personal obsession in one figure.
Kang remains a fascinating character, especially in comic storytelling built around paradox, recurrence, and variants. But that same complexity can dilute urgency in film if audiences are unsure which version matters most. Doom is more immediate. He is not just another variant in a crowd; he is usually the room’s most dangerous person by default. That is likely why Feige’s comments frame Doom as the one character who could fill the post-Thanos vacuum at this scale.

Avengers: Doomsday Doctor Doom role and story setup
Marvel has officially confirmed that Avengers: Doomsday is the next Avengers film, that the Russo brothers are directing it, and that Robert Downey Jr. is playing Doctor Doom. Marvel’s official pages and trailer materials place Doom at the center of the crossover, while recent reporting on CinemaCon footage describes Doom as preparing to invade the multiverse and battling heroes such as Thor.
That suggests Doomsday is no minor introduction. It appears designed as the film where Doom becomes the saga’s active, present-tense crisis. Rather than merely inheriting Kang’s slot in name only, Doom seems set up as the villain whose actions force the Avengers, the Fantastic Four, the X-Men, and other MCU factions into direct collision before Secret Wars.
Fantastic Four post-credits scene and Doctor Doom teases
By now, Doctor Doom is no longer only a Comic-Con concept. Reporting on The Fantastic Four: First Steps states that Doctor Doom appears in the film’s post-credits material, with coverage describing a brief but important scene involving Franklin Richards and a cloaked Doom figure later confirmed to be Downey’s character.
That tease matters because it ties Doom directly to Marvel’s First Family, which is where many fans expected his MCU foundation to begin. It also links the villain not just to a generic multiverse threat but to specific emotional and cosmic stakes involving Reed, Sue, and Franklin. In other words, Doom is being positioned not only as a crossover destroyer but as a character with narrative roots in Fantastic Four mythology.
What happened to Avengers: The Kang Dynasty plans
Avengers: The Kang Dynasty was once the official title for the first of the two Multiverse Saga Avengers finales. Marvel announced it at Comic-Con 2022, but the project was later reworked. At Comic-Con 2024, Marvel officially revealed the new title Avengers: Doomsday instead, with the Russo brothers directing and Downey returning as Doom.
In practical terms, The Kang Dynasty did not survive as the same movie under a different coat of paint. The change in title signaled a change in core villain architecture. The film that was supposed to center Kang as a dynasty-building, multiversal ruler was replaced by a movie built around Doom as the event-level antagonist leading into Secret Wars.

How Loki connects to the Kang storyline after Quantumania
Loki is still essential to understanding the Kang storyline because the series introduced He Who Remains, explicitly tied Jonathan Majors to the wider Kang concept, and established the timeline chaos that made the Multiverse Saga possible. Marvel’s own coverage of the Loki Season 1 finale says He Who Remains is played by Majors and directly points ahead to Quantumania, while Marvel later explained that the end of Loki reactivated the multiverse in ways that enabled later stories such as No Way Home and Doctor Strange in the Multiverse of Madness.
After Season 2, Loki remains relevant even if Kang is no longer the main saga villain. The show ends with Loki sacrificing himself to preserve the timelines and protect the TVA’s broader mission, which means the infrastructure of multiversal storytelling remains intact even if the franchise’s primary enemy has changed. The TVA, variant logic, and timeline instability still matter; what changed is who stands at the top of the villain pyramid.
MCU Phase 6 changes after the Kang-to-Doom pivot
The Kang-to-Doom pivot changed Phase 6 at both the branding and story levels. Instead of moving from a Kang-led Avengers film into Secret Wars, Marvel is now moving from The Fantastic Four: First Steps and other Phase 6 stories into Avengers: Doomsday and then Avengers: Secret Wars, both led by the Russo brothers and both officially tied to Downey’s Doom.
It also changed the emotional center of the saga. A Kang-led endgame would have been built on Loki, time warfare, and variant escalation. A Doom-led endgame shifts more weight toward Fantastic Four, multiversal incursion-style conflict, and the return of a more traditional Marvel supervillain structure. That does not erase Phase 4 and Phase 5’s multiverse setup, but it does redirect where all that setup is pointing.
Will Kang return in Avengers: Secret Wars?
As of April 21, 2026, Marvel has not officially announced Kang for Avengers: Secret Wars. Marvel’s current official page for Secret Wars lists Robert Downey Jr. in the cast and gives the film a December 17, 2027 release date, but it does not publicly confirm Kang’s involvement.
That means Kang’s return remains possible in theory but unconfirmed in practice. Because Loki and the broader multiverse concept established variants across timelines, Marvel could always reintroduce some version of Kang later. But the studio’s public-facing strategy now centers Doom, not Kang, and that is the safest basis for any current analysis.

What the Kang-to-Doctor-Doom switch means for the MCU’s future
The Kang-to-Doctor-Doom switch means Marvel is choosing clarity over continuity. Rather than preserving every piece of the original Kang roadmap, the studio has prioritized a villain with stronger recognition, cleaner narrative gravity, and deeper ties to characters Marvel now fully controls onscreen, especially the Fantastic Four.
It also suggests that Marvel is entering a more flexible era of long-term planning. The Multiverse Saga is no longer a rigid march from one announced endpoint to another. It is a live franchise that can respond to audience reaction, creative reassessment, corporate reality, and actor-driven disruption. The result may be messier than the Infinity Saga’s famous precision, but it may also produce a stronger finale if Doom delivers the kind of commanding villain presence Marvel now openly admits it wanted all along.

conclusion
Marvel’s move away from Kang and toward Robert Downey Jr.’s Doctor Doom was not just a reaction to scandal. Kevin Feige’s comments make clear that Marvel had already started doubting Kang’s ability to carry the Multiverse Saga as its defining villain around the Quantumania period. Jonathan Majors’ legal fallout intensified that problem, but it did not create it from nothing.
The result is one of the biggest strategic pivots in MCU history. Avengers: The Kang Dynasty gave way to Avengers: Doomsday. Kang’s rise stalled. Doom took the throne. And with The Fantastic Four: First Steps, Avengers: Doomsday, and Avengers: Secret Wars now forming the spine of Phase 6, Marvel is betting that a more iconic, more forceful, and more immediately legible villain can restore the kind of saga-ending momentum the studio once had with Thanos.
