The Multiverse Saga

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Real-World Creation and Announcement

The Multiverse Saga was officially announced by Marvel Studios President Kevin Feige on July 23, 2022, during the studio's Hall H panel at San Diego Comic-Con. This announcement provided a formal structure and title to the collection of films and television series that began after Avengers: Endgame (2019). Feige laid out a detailed roadmap for Phases Four, Five, and Six, confirming that the sprawling, seemingly disconnected stories of Phase Four were, in fact, laying the groundwork for a multiversal conflict. This reveal was a direct parallel to how Feige had previously outlined The Infinity Saga, providing fans with a sense of direction and culminating in two new Avengers films: Avengers: The Kang Dynasty and Avengers: Secret Wars. The creative impetus for the saga stems from a desire to escalate the stakes beyond the universe-level threat of Thanos. By introducing the multiverse, the creative teams at Marvel Studios unlocked infinite storytelling possibilities, allowing for the introduction of alternate versions of beloved characters (variants), the integration of characters from previous non-MCU Marvel films (such as those from Fox and Sony), and the adaptation of some of Marvel Comics' most celebrated and reality-bending storylines.

In-Universe Origin Story

The seeds of the Multiverse Saga were planted within the Infinity Saga, but they only began to sprout and grow into the primary narrative following the defeat of Thanos. The origin of the conflict is a complex tapestry woven across multiple projects.

The Foundational Concepts in Earth-616 (Prime Comic Universe)

While the MCU's “Multiverse Saga” is a new construct, its conceptual roots are deeply embedded in decades of Marvel Comics history. The Marvel Multiverse was first explicitly mentioned in Captain Britain #279 (1976) by writer Chris Claremont, which designated the prime Marvel Universe as Earth-616. However, the idea of alternate realities had been explored even earlier. The foundational event that serves as the primary inspiration for the saga is the 2015 storyline Secret Wars, written by Jonathan Hickman. This epic event was the culmination of his multi-year run on Avengers and New Avengers. Hickman introduced the concept of Incursions: a cosmic phenomenon where two parallel Earths from different universes are drawn to the same point in space-time. If they collide, both universes are annihilated. The only way to prevent this is for one of the Earths to be destroyed first. This created a moral crisis for the Illuminati (a secret cabal of Marvel's greatest minds), who were forced to build planet-killing weapons to destroy other Earths to save their own. The Incursions were revealed to be the result of the premature death of the Eternity of one universe, orchestrated by beings known as the Beyonders. The Incursions caused the “death” of the entire Marvel Multiverse, with the only survivors being those who escaped on a “life raft.” Doctor Doom, having stolen the power of the Beyonders, used their might to stitch together the remnants of dead realities into a new patchwork planet called Battleworld, which he ruled as God-Emperor Doom. This comic storyline established the key elements the MCU would later adapt:

Marvel Cinematic Universe (MCU)

The in-universe origin of the MCU's Multiverse Saga is the direct consequence of the Avengers' actions in Avengers: Endgame. The “Time Heist” required them to tamper with history, creating branching timelines. Though Captain America seemingly “clipped” these branches by returning the Infinity Stones, the damage was done. The true catalyst, however, was revealed in the Disney+ series Loki. The series introduced the Time Variance Authority (TVA), an organization that existed outside of time and was tasked with pruning any timeline that deviated from the “Sacred Timeline.” It was revealed that a multiversal war had previously broken out between infinite variants of a 31st-century scientist named Nathaniel Richards. One variant, He Who Remains, discovered a creature called Alioth that could consume time and space. He weaponized it, ended the war, and isolated a single “Sacred Timeline” to prevent his more malevolent variants (all known as Kang the Conqueror) from ever coming into existence. He created the TVA to maintain this fragile peace. The saga officially begins when Sylvie, a female Loki variant, kills He Who Remains in the Season 1 finale of Loki. His death shatters the Sacred Timeline, causing it to branch uncontrollably into an infinite number of parallel universes, thus birthing the modern MCU multiverse. This single act unleashed all of Kang's variants back into reality and set the stage for the coming war. Subsequent projects built upon this foundation:

Part 3: Timeline, Key Turning Points & Core Concepts

This saga is defined by several new, complex cosmic rules and a carefully structured release slate that builds the narrative piece by piece.

Core Concepts Explained

To fully understand the Multiverse Saga, one must grasp its foundational terminology, which often differs slightly between the comics and the MCU.

What is a Variant?

A “Variant” is any individual who deviates from their prescribed path on a timeline, causing a new, branching timeline to be created.

What is an Incursion?

An Incursion is a destructive event where two universes collide, resulting in the annihilation of one or both.

The Sacred Timeline and the TVA

MCU Saga Timeline

The Multiverse Saga is officially divided into three phases.

Phase Four (2021-2022) - The Aftermath and Introduction

Phase Four deals with the fallout from the Infinity Saga while simultaneously introducing the core concepts and characters of the Multiverse Saga. Its projects are often more character-focused and seemingly disconnected, but they all explore themes of identity, grief, and the consequences of past events.

Phase Five (2023-2025) - The Rise of Kang

Phase Five shifts the focus directly to the central conflict, with Kang the Conqueror emerging as the primary antagonist. This phase is designed to build Kang's threat level and show the heroes struggling to comprehend the scale of the war they are in.

Phase Six (2025-2027) - The Secret Wars

Phase Six is the grand finale of the saga, culminating in a conflict that threatens all of reality.

Part 4: Central Characters & Antagonists

Unlike the Infinity Saga, which had a clear focal point in Thanos, the Multiverse Saga features a more complex and decentralized network of heroes and villains.

Part 5: Architectural Pillars of the Saga (MCU)

While the saga is sprawling, a few key projects serve as the primary load-bearing walls for its narrative architecture.

Loki (Season 1)

This series is the Genesis block of the Multiverse Saga. It took the abstract concept of “branch timelines” from Endgame and codified it with a rich, detailed lore. It established the rules: the Sacred Timeline, the TVA, the concept of pruning, and the existence of variants. Most importantly, its finale, “For All Time. Always.”, is the inciting incident for the entire saga. The choice Sylvie makes to kill He Who Remains is the single moment the multiverse is irrevocably broken, setting every subsequent story in motion.

Spider-Man: No Way Home

If Loki opened the door to the multiverse, No Way Home blew the hinges off for a mainstream audience. The film served as a powerful, emotional proof-of-concept. It demonstrated that the stakes were not just about saving the world, but about the very fabric of identity and reality. By successfully integrating characters from two prior, non-MCU film series, it primed audiences for the “anything is possible” nature of the saga and celebrated Marvel's cinematic history, a key theme of a multiversal narrative.

Doctor Strange in the Multiverse of Madness

This film was the first direct exploration of the chaotic, untamed multiverse post-Loki. It visualized the concept of universe-hopping in a visceral way and, critically, introduced the saga's ticking clock: Incursions. The film established that multiversal travel is inherently dangerous and has apocalyptic consequences. It also elevated the Scarlet Witch to a multiversal-level threat, demonstrating that the dangers of this new era wouldn't just come from Kang.

Ant-Man and the Wasp: Quantumania

This film's primary function was to formally introduce the saga's main antagonist. It moved Kang from a theoretical threat (He Who Remains) to a physical, formidable, and personal one. The film established his powers, his motivations (conquest and escaping exile), and his history of wiping out entire timelines. The mid-credits scene revealing the Council of Kangs was a pivotal moment, transforming the threat from a single villain into an infinite army and setting the stage for The Kang Dynasty.

Part 6: Variants and Alternative Versions

The concept of “variants” is the creative lifeblood of the Multiverse Saga, allowing for endless reinterpretation of classic characters. In the MCU: The saga has already introduced numerous variants that have played significant roles. The Council of Kangs is the most prominent example, but the various Lokis (Sylvie, Classic Loki, Kid Loki, Boastful Loki, Alligator Loki) were the first to be explored in depth. Multiverse of Madness introduced the Illuminati of Earth-838, featuring variants like Captain Carter (Hayley Atwell), Captain Marvel (Lashana Lynch), Professor X (Patrick Stewart), and Mister Fantastic (John Krasinski). No Way Home featured hero variants (Tobey Maguire's and Andrew Garfield's Spider-Men) and villain variants (Willem Dafoe's Green Goblin, Alfred Molina's Doctor Octopus). In Marvel Comics: The concept has been a staple for over 60 years. Entire universes have been built around variants.

1)
The working title for Avengers: The Kang Dynasty was Avengers: Anchorage.
2)
The title “The Multiverse Saga” is a direct parallel to “The Infinity Saga,” helping to brand the MCU's long-form storytelling into distinct chapters for audiences.
3)
Jonathan Hickman's run on Avengers and New Avengers from 2012-2015 is considered the primary source material for the concepts of Incursions and the multiversal collapse that will be adapted in Avengers: Secret Wars.
4)
The introduction of Patrick Stewart as Professor X in Multiverse of Madness was a landmark moment, as it was the first time a character from the Fox-produced X-Men films appeared within an MCU project, directly linking those films to the wider Marvel multiverse.
5)
The concept of a Council of Kangs is lifted directly from the comics, first appearing in Avengers #292 (1988). Their comic book counterparts were a council of three Kangs who sought to eliminate all divergent Kangs from the timeline.
6)
Due to off-screen issues involving actor Jonathan Majors, there has been speculation and reporting that Marvel Studios may be pivoting away from Kang as the central antagonist or changing the title of Avengers: The Kang Dynasty. As of late 2023, no official changes have been announced.
