What If...?

• Core Identity: What If…? is a long-running Marvel Comics anthology series and a Marvel Cinematic Universe animated series that explores how history would have unfolded if key moments in the Marvel Universe had occurred differently.
• Key Takeaways:
• Role in the Universe: It serves as a narrative framework for exploring the infinite possibilities of the Multiverse. Each story is traditionally presented from the perspective of Uatu the Watcher, an omniscient cosmic being who observes, but is sworn never to interfere with, alternate timelines created by a single divergent choice.
• Primary Impact: What If…? was instrumental in popularizing the concept of a Marvel Multiverse for readers and viewers. It provides a creative sandbox for writers and artists to tell self-contained, often tragic or ironic, stories without altering the main continuity, and has occasionally served as a testing ground for concepts that were later integrated into the prime universe.
• Key Incarnations: The original comic book series consists of standalone, speculative anthology issues with no connection to one another. In contrast, the Marvel Cinematic Universe animated series, while also an anthology, builds a season-long narrative arc where the individual stories ultimately converge, forcing the Watcher to intervene and assemble a team known as the Guardians of the Multiverse.

The concept of What If…? was conceived by veteran Marvel writer Roy Thomas, who was inspired by a 1950s DC Comics story titled “What If Superman Ended the War?”. Thomas proposed a similar series for Marvel, focusing on pivotal moments in its own burgeoning history. The idea was to take a critical event—a hero's origin, a villain's victory, a character's death—and twist it just enough to send the timeline careening in a new direction. The series debuted with What If? #1 in February 1977. The inaugural issue asked the question, “What If Spider-Man Had Joined the Fantastic Four?”. This first story set the tone for the entire franchise: it took a well-known event from early in a hero's career (from The Amazing Spider-Man #1) and explored the logical, and often unforeseen, consequences of a different choice. The series was an immediate success, resonating with fans who loved to speculate on the “what ifs” of their favorite stories. The original volume ran for 47 issues until 1984. It was characterized by its often somber and tragic endings, reinforcing the idea that the events of the main Earth-616 continuity, however difficult, often led to the best possible outcome. These stories were narrated by Uatu the Watcher, whose presence framed the series as a glimpse into his cosmic observations. A second, more extensive volume of What If…? was launched in 1989 and ran for 114 issues, plus several specials, until 1998. This volume continued the tradition of the first but also introduced more humor and variety, including a famous issue (#34) that was entirely comedic. It also began to more formally interact with the burgeoning concept of the Marvel Multiverse, with some of its realities later being assigned official “Earth” designations in Marvel handbooks. Since the end of the second volume, Marvel has periodically revived the What If…? title for one-shots or limited series, often tying into major comic book events like Civil War, Annihilation, or Spider-Verse. These modern iterations continue to explore alternate timelines, reflecting the contemporary state of the Marvel Universe and solidifying the brand as a cornerstone of Marvel's multiversal storytelling.

The in-universe “origin” of What If…? is intrinsically tied to the nature and purpose of Uatu the Watcher. The Watchers are an ancient, immensely powerful cosmic race who, after a disastrous early attempt to share their technology with a lesser species resulted in that species' self-destruction, took a sacred vow of absolute non-interference. Their sole purpose is to observe and chronicle all of existence, from the birth of galaxies to the smallest choices of mortal beings. Uatu was assigned to observe Earth and its solar system. From his base on the Blue Area of the Moon, he has witnessed every major event in the history of Earth-616's heroes and villains. The What If…? comic series is presented as Uatu turning his cosmic senses away from the prime timeline to peer into adjacent realities. These are not mere fantasies; they are real, divergent timelines that splintered off from Earth-616 at a critical moment, known as a “Divergence Point” or “Nexus Event.” For example, in the prime timeline, Gwen Stacy died during a battle between Spider-Man and the Green Goblin. Uatu, in his role as narrator, would show the reader this established fact and then state, “But in another universe, in another reality… what if Spider-Man had saved Gwen Stacy?” He then proceeds to narrate the events of that new timeline, which now exists as a separate strand in the great web of the Multiverse. His narration is the framing device that gives these stories their context and authority, positioning them as factual accounts of alternate worlds rather than simple speculation. While he is bound by his oath, his choice to share these stories with the reader is, in itself, a form of subtle interaction, born from his deep, often paternal, affection for humanity.

The origin of the concept in the MCU is established in the Disney+ animated series What If…?, which premiered in 2021. The series begins after the events of the Loki (TV series) finale, where the “Sacred Timeline” was shattered, allowing the Multiverse to branch into infinite possibilities. The MCU's Watcher (voiced by Jeffrey Wright) introduces himself in a manner nearly identical to his comic book counterpart. He is a cosmic observer, chronicling the vast new realities that have sprung into existence. His monologue defines the core premise for the audience: “I observe all that transpires here, but I do not, cannot, will not interfere. For I am the Watcher.” Each episode begins with him identifying a key moment from the MCU's “Infinity Saga” and posing a question that creates a new universe. For example, “What If… Captain Carter Were The First Avenger?” explores a universe where Peggy Carter, not Steve Rogers, received the Super-Soldier Serum. The crucial difference from the comics is that the MCU's What If…? series is not just an anthology; it has a distinct narrative arc. The Watcher's vow of non-interference is tested and ultimately broken. When a variant of Ultron from one of these realities successfully acquires the Infinity Stones, becoming Infinity Ultron, he becomes aware of the Watcher and the Multiverse itself. This “ultra-vision” allows him to transcend his own universe and threaten all of reality. This unprecedented threat forces the Watcher to abandon his oath and actively recruit heroes from the universes he has observed—including Captain Carter, Star-Lord T'Challa, and Doctor Strange Supreme—to form the Guardians of the Multiverse and fight back. This adaptation transforms the Watcher from a passive narrator into a reluctant, but pivotal, protagonist in the first saga of the MCU's Multiverse.

This section analyzes the core components of the What If…? concept, comparing its implementation in the comics and the MCU.

• Narrative Structure:
  • The Classic Formula: A typical What If…? comic follows a rigid but effective structure.

1. Introduction: Uatu the Watcher appears and addresses the reader directly.

    2.  **The Constant:** He briefly recaps a well-known event from Earth-616 history as it "should" have happened.
    3.  **The Divergence:** He identifies the single, precise moment where a different choice was made or a different outcome occurred.
    4.  **The Consequence:** The rest of the issue is a detailed narrative exploring the domino effect of that single change, showing how heroes, villains, and the world itself are altered.
    5.  **Conclusion:** The story usually concludes with an ironic, tragic, or thought-provoking ending, often with Uatu providing a final, solemn piece of commentary.
*   **Core Themes:**
  *   **Tragedy and Irony:** The most pervasive theme in the comic series is that of tragedy. Many stories end with the hero making a noble choice that leads to a far worse outcome than in the prime reality. A classic example is //What If?// (vol. 1) #24, "What If Spider-Man Had Saved Gwen Stacy?". In this reality, his success leads him to reveal his identity, which a vengeful J. Jonah Jameson uses to ruin his life, ultimately leading to a far more miserable existence. These endings often served to validate the often-painful canon of Earth-616.
  *   **Unintended Consequences:** The stories are powerful explorations of chaos theory. A small change, like a different hero finding a powerful artifact or a villain surviving a key battle, spirals into world-altering consequences, demonstrating how fragile the established timeline truly is.
  *   **The Nature of Heroism:** By placing familiar characters in unfamiliar circumstances, //What If...?// tests the core of their heroism. "What if Captain America was revived in the present day?" explores a world where a fascist America has taken over, forcing Steve Rogers to become a rebel against the very country he symbolizes.
*   **Canon and Continuity:**
  *   For decades, //What If...?// stories were considered strictly non-canonical "imaginary stories." They existed in a bubble, allowing creators to kill major characters or destroy the world without consequence. However, with the formalization of the Marvel Multiverse in series like //Exiles// and later event comics, this perception changed. Marvel began officially designating many of these alternate realities with their own Earth numbers (e.g., the world where Jane Foster became Thor was designated Earth-788). This retroactively integrated these "imaginary stories" into the larger, official Multiverse, making them just as "real" as Earth-616, merely different.

• Narrative Structure:
  • Anthology with a Meta-Plot: The first season of the MCU's What If…? largely follows the anthology format, with each episode telling a complete, self-contained story. However, it deviates significantly from the comic's purely episodic nature by weaving a subtle, and then overt, meta-narrative throughout the season.
  • Convergent Storytelling: Characters and plot points from earlier episodes reappear and become crucial in the finale. For example, the malevolent Doctor Strange Supreme from Episode 4 is later recruited by the Watcher for his knowledge of dark magic. The final two episodes fully abandon the anthology format to tell a single, serialized story about the fight against Infinity Ultron, uniting the season's protagonists.
• Core Themes:
  • Hope and Heroism: While the MCU series contains incredibly dark and tragic episodes (most notably the story of Doctor Strange Supreme), its overarching theme is more hopeful than the comic's typical output. Heroes like Captain Carter and Star-Lord T'Challa create demonstrably better universes through their actions. The finale, where a disparate group of variants unite to save the Multiverse, is a triumphant celebration of heroism in all its forms.
  • Found Family: A recurring MCU theme, the concept of a found family is central to the formation of the Guardians of the Multiverse. These individuals, torn from their own worlds and losses, find common cause and camaraderie, echoing the arcs of the mainline Avengers and Guardians of the Galaxy.
  • The Price of Power: The series also deeply explores the corrupting nature of power, most vividly through Doctor Strange Supreme, who destroys his entire universe in a selfish attempt to save Christine Palmer, and Infinity Ultron, whose logic of “peace” leads him to seek the destruction of all life in every universe.
• Impact on MCU Canon:
  • Unlike the comics' initially ambiguous canonical status, the MCU's What If…? was established as fully canonical to the Multiverse from the start. It serves as a crucial primer for the MCU's “Multiverse Saga.” Its direct impact has already been seen with the live-action appearance of Captain Carter (a variant of the one from the show) in Doctor Strange in the Multiverse of Madness. The series introduces and explains key multiversal concepts like Variants, Nexus Events, and Absolute Points in time to a mainstream audience, laying the essential groundwork for future films and series.

The one constant across nearly every iteration of What If…? is its narrator. Uatu the Watcher is the audience's guide through the Multiverse. In the comics, he is a figure of immense gravitas and cosmic loneliness, whose affection for humanity constantly strains against his sacred vow of non-interference. On the rare occasions he has broken his vow in the main continuity, it has been to help Earth's heroes against a universe-ending threat like Galactus. His role in What If…? is his “safe” way of interacting, sharing the stories of others without directly acting himself. The MCU's Watcher begins this way but undergoes a significant character arc, moving from passive observer to active participant out of necessity, transforming him into one of the Multiverse's most important defenders.

This is the core mechanic of every What If…? story. A Divergence Point, later termed a “Nexus Event” in the MCU's Loki series, is the exact moment a timeline splits. It's the single variable that changes everything.

• Comic Examples: What if Peter Parker's Uncle Ben had not died? What if Doctor Doom had become a hero? What if the X-Men died on their first mission?
• MCU Examples: What if Yondu had abducted T'Challa instead of Peter Quill? What if a zombie virus arrived on Earth during the events of Infinity War? What if Killmonger rescued Tony Stark in Afghanistan?

Answering the question, “What is a Nexus Event in Marvel?” is central to understanding the What If…? premise: it is the genesis of a new universe.

A concept unique to the MCU, this team was hastily assembled by the Watcher in a desperate attempt to stop Infinity Ultron from destroying the Multiverse. They represent the “greatest” heroes from the realities the Watcher had observed. The founding roster includes:

• Captain Carter: The super-soldier leader.
• Star-Lord T'Challa: A charismatic Ravager who redeemed Thanos.
• Doctor Strange Supreme: An immensely powerful but dangerous sorcerer who absorbed countless demons.
• Party Thor: An exuberant, powerful, but immature version of the God of Thunder.
• Gamora (What If...: A variant who killed Thanos and wields his armor and blade.
• Erik Killmonger: A brilliant strategist who briefly wore an Iron Man-style suit and the Black Panther habit.
• Black Widow (What If...: The sole survivor of a universe destroyed by Ultron, providing crucial intelligence.

Long before Jason Aaron's celebrated run on Thor, this classic issue explored the idea of Jane Foster proving worthy of Mjolnir. In this reality, it is Jane, not Donald Blake, who finds the enchanted cane and becomes a hero named “Thordis.” The story follows her journey as she battles Loki and navigates her relationship with Asgard. While Odin is initially displeased, Jane ultimately proves her worthiness and is welcomed as a goddess. This story is a prime example of a What If…? concept being so compelling that it eventually influenced the main Earth-616 continuity decades later, providing a conceptual blueprint for Jane Foster's beloved tenure as the Mighty Thor.

This is arguably one of the most famous and heartbreaking What If…? stories ever published. In this timeline, Spider-Man successfully catches and saves Gwen Stacy. Overjoyed, he reveals his identity as Peter Parker to her, and they become engaged. However, their happiness is short-lived. The Green Goblin, knowing Spider-Man's identity, mails proof to J. Jonah Jameson, who exposes Peter to the world. Hounded, unable to find work, and living as a fugitive, Peter is eventually cornered by the police. The story ends with Peter and a still-loyal Gwen on the run, their lives destroyed not by a supervillain's plot, but by the consequences of their own happiness. It is a quintessential example of the series' often tragic and ironic tone.

Considered by many fans and critics to be the high point of the MCU series, this episode is a masterpiece of tragic storytelling. In this universe, the car crash that cost Stephen Strange the use of his hands instead claims the life of his love, Dr. Christine Palmer. This loss, not professional ambition, drives him to Kamar-Taj. After becoming the Sorcerer Supreme, he becomes obsessed with reversing her death. The Ancient One reveals that Christine's death is an “Absolute Point” in time—an unchangeable event that ensures Strange's path to becoming Sorcerer Supreme. Refusing to accept this, Strange spends centuries absorbing dark beings to gain enough power to break the Absolute Point. He succeeds, but the resulting paradox unravels his entire universe, leaving him as the sole, heartbroken survivor in a prison of his own making, a grim figure known as Doctor Strange Supreme.

This episode serves as the climactic turning point for the first season of the MCU series. In this reality, Ultron successfully uploads his consciousness into a new body made of Vibranium and acquires the Mind Stone. He defeats the Avengers and unleashes a global nuclear holocaust. When Thanos arrives on Earth with the other five Infinity Stones, Ultron instantly bisects him and claims the stones for himself. Now wielding the power of a god, Infinity Ultron creates a massive drone army and begins destroying all life in his universe. His purpose fulfilled, he falls silent until he senses a new presence: the Watcher. Having achieved cosmic awareness, Ultron breaks through the barriers of reality itself, invading the Watcher's observatory and threatening to extend his genocidal campaign to every universe in the Multiverse, setting the stage for the season finale.

The concept pioneered by What If…? has had a profound and lasting impact on Marvel storytelling, extending far beyond the confines of its own title. It normalized the idea of alternate realities, paving the way for more complex multiversal narratives.

The comic series Exiles, launched in 2001, can be seen as the logical evolution of the What If…? concept. Instead of merely observing alternate realities, this series featured a team of heroes (including variants of Blink, Morph, and Sabretooth) who were plucked from their own divergent timelines. Their mission was to travel across the Multiverse, repairing “broken” realities to prevent them from collapsing and threatening the entire cosmic structure. It took the passive observation of What If…? and turned it into an active, ongoing superhero adventure.

The multiverse-spanning Spider-Verse events owe a massive conceptual debt to What If…?. These stories brought together hundreds of Spider-People from different realities, many of whom were effectively “What If” characters. The most famous example is Gwen Stacy as Ghost-Spider (formerly Spider-Gwen). While she technically debuted in Edge of Spider-Verse #2, her concept—“What if Gwen Stacy was bitten by the radioactive spider?”—is pure What If…?. The series provided the framework for thinking about character variations that became the bedrock of the Spider-Verse.

The most significant modern legacy of What If…? is its role as the foundational text for the MCU's Phases Four, Five, and Six, collectively known as the “Multiverse Saga.” The animated series was not a side project; it was the mainstream audience's formal introduction to the very concepts that drive the overarching plot of the modern MCU. It explained what a variant is, showed the devastating consequences of tampering with time, and established that infinite versions of beloved characters exist. The narratives of Loki (TV series)Quest for a Time, No Way Home, and Doctor Strange in the Multiverse of Madness all rely on the audience's understanding of the principles first laid out in a clear, accessible way by the Watcher in What If…?. It is the narrative and thematic cornerstone of Marvel's current cinematic direction.
