Eternity

• Core Identity: Eternity is the sentient, abstract cosmic entity that embodies all of time and reality within a single Marvel Universe, serving as the literal personification of the universe itself.
• Key Takeaways:
• Role in the Universe: Eternity is the de facto supreme being of its universe, representing the sum total of all life, space, and time. It is a fundamental force of existence, sibling to Infinity (who represents space), and subordinate only to the multiversal authority of the Living Tribunal. Its health and well-being are directly tied to the stability of its reality.
• Primary Impact: As the universe personified, Eternity's primary impact is passive; its existence is the stage upon which all stories unfold. However, when the universe faces an existential threat that lesser powers cannot handle, Eternity may manifest or empower a champion, most frequently Doctor Strange, to act on its behalf. Its defeat or imprisonment, as seen in storylines like The Infinity Gauntlet and Ultimates, signals a catastrophe of the highest possible order.
• Key Incarnations: The distinction between the comic and film versions is profound. In the Earth-616 comics, Eternity is an active (though often cryptic) and immensely powerful consciousness that can be communicated with and even fought. In the Marvel Cinematic Universe, Eternity is depicted not as a sentient being but as a passive, sacred location at the center of the universe that grants a single, all-powerful wish to the first being to reach it.

Eternity first appeared in Strange Tales #138, published in November 1965. The character was a co-creation of writer Stan Lee and, most significantly, artist Steve Ditko. Ditko's groundbreaking, surreal, and psychedelic art style was the driving force behind the cosmic and mystical corners of the nascent Marvel Universe. Eternity was the apotheosis of this creative direction. The introduction of Eternity was a pivotal moment in comics history. It represented a bold move away from conventional heroes-and-villains storytelling into mind-bending, philosophical high-concept fantasy. Ditko's visual design for Eternity—a vast, human-shaped silhouette filled with a starscape, containing all of existence within its form—was instantly iconic. It visually communicated the entity's immense scale and abstract nature in a way that words alone could not. This character, alongside others like Dormammu and the Living Tribunal, cemented Doctor Strange's comics as the place where the conceptual boundaries of the Marvel Universe were explored and defined. Eternity's creation was a direct product of the Silver Age's creative explosion, reflecting a cultural interest in cosmic consciousness, metaphysics, and exploring the unknown.

The origin of Eternity is synonymous with the origin of the universe itself. Understanding its existence requires delving into the deepest cosmology of the Marvel Multiverse.

Eternity was not so much “born” as it “became.” At the dawn of creation, with the event known as the Big Bang, all matter, energy, space, and time exploded into existence from a singularity. Eternity is the sentient consciousness of that totality. It is the collective consciousness of every living thing in the universe across all moments in time, from the first spark of life to the final entropic heat death. Marvel's cosmology has been retconned and expanded multiple times, adding layers to this origin. The current understanding posits that the Multiverse has gone through several iterations or “Cosmos.” The very first universe was a singular, sentient being called the First Firmament. It was a lonely and perfect state of being. The creation of the Celestials, who desired a dynamic, evolving multiverse of life and death, led to a cosmic war that shattered the First Firmament. From these shattered fragments, the Second Cosmos and the first Multiverse were born. This cycle of destruction and rebirth has repeated, with the mainstream Marvel Universe (Earth-616) existing within the Seventh Cosmos before its destruction in the 2015 Secret Wars event and subsequent rebirth as the Eighth Cosmos. Within each universe of this multiverse, an Eternity entity comes into being. Our Earth-616 Eternity is therefore the embodiment of the Eighth iteration of this specific universal stream. It has a “sister” entity, Infinity, who represents the boundless potential of space, while Eternity represents the linear progression of time. Together, they form the complete space-time continuum. As an abstract entity, Eternity is not truly male or female, but its consciousness is so vast that it can manifest avatars, or “M-Bodies,” to interact with lesser beings. It most commonly chooses a male-presenting form, but this is merely a construct for the benefit of mortal perception. Its first chronological interaction with a human was with the Sorcerer Supreme, Doctor Stephen Strange. When the tyrannical Faltine entity Dormammu threatened to absorb Earth's dimension, Strange realized he was outmatched. He journeyed through the fabric of reality, seeking a power greater than his foe, and ultimately came before Eternity itself. By proving his worthiness, Strange convinced Eternity to intervene, and the entity easily banished Dormammu, establishing a long-standing (if distant) relationship between Eternity and the Sorcerer Supreme, Earth's mystical protector.

The MCU's interpretation of Eternity is a radical departure from the comics, prioritizing narrative function over cosmic lore. First glimpsed visually during Peter Quill's celestial empowerment in Guardians of the Galaxy Vol.2 and as a dimension Doctor Strange is thrown through in Doctor Strange in the Multiverse of Madness, its true nature and purpose were revealed in Thor: Love and Thunder. In this continuity, Eternity is not a sentient being but a specific, physical (or quasi-physical) location: The Gates of Eternity, found at the very center of the universe. It is a place of immense power that is considered sacred and nigh-unreachable. According to legend, the first person to reach its altar will be granted a single, perfect wish—anything their heart desires. This cosmic boon is not easily accessed. Reaching the Gates of Eternity requires the Bifrost Bridge, which can only be summoned by a powerful Asgardian weapon like Thor's axe, Stormbreaker. The film's antagonist, Gorr the God Butcher, learns of this legend. Corrupted by the Necrosword, his goal is to reach Eternity and wish for the death of all gods in the universe. The MCU's origin for Eternity is therefore not tied to the Big Bang or the birth of consciousness, but framed as a mythological destination, a form of “cosmic genie.” This change serves several key storytelling purposes:

• Simplification: It avoids the complex, abstract nature of the comic book entity, which would be difficult to explain in a single film.
• Narrative Drive: It creates a clear, tangible goal for the villain and a specific location for the film's climax. The “race to Eternity” becomes the central plot engine.
• Emotional Core: It allows for the film's powerful resolution, where a dying Gorr, convinced by Thor and Jane Foster, uses his wish not for vengeance, but to resurrect his deceased daughter, Love. Eternity silently facilitates this act of love, giving the concept a thematic weight that resonates with the film's title.

The MCU's Eternity is a passive, silent force—a cosmic tool or mechanism—rather than the active, thinking, and feeling universal consciousness of the comics.

As the embodiment of an entire universe, Eternity's capabilities are, by definition, nearly limitless. However, there are crucial differences in how this power is expressed between the comics and the MCU.

Eternity's power is intrinsic to its being. It doesn't “use” power; it is power. Its abilities are best understood as fundamental attributes of reality itself.

• Core Nature:
• Abstract Embodiment: Eternity is a conceptual being. It is the sum of all things within its universe. An attack on Eternity is an attack on reality itself.
• Cosmic Hierarchy: It exists as one of the primary cosmic abstracts, alongside Infinity, Death, and Oblivion. Above them all is the Living Tribunal, the multiversal judge who ensures the cosmic laws are followed. Eternity can be, and has been, overruled by the Tribunal.
• Powers and Abilities:
• Nigh-Omnipotence: Within the confines of its own universe, Eternity's power is virtually absolute. It can manipulate reality on a universal scale, altering the fundamental laws of physics, creating or destroying galaxies, and restructuring space-time at will. Its power is only surpassed by the Living Tribunal and extra-dimensional beings like the Beyonders or trans-universal artifacts like the Heart of the Universe.
• Nigh-Omniscience: As the collective consciousness of all life and time, Eternity knows virtually everything that has happened, is happening, and will happen within its universe. This knowledge is not always perfect, as beings who exist outside of normal time or those who can manipulate probability can obscure their actions from it.
• Nigh-Omnipresence: Eternity exists everywhere and everywhen at once. It is the fabric of space and the flow of time.
• Reality Warping: This is its most fundamental ability. It can bring thoughts into existence, erase beings from reality, and reshape the cosmos according to its will, though it rarely does so directly, preferring to maintain the natural flow of causality.
• Manifestation (M-Bodies): To interact with mortals, Eternity projects avatars known as M-Bodies. These are finite, physical constructs that contain an infinitesimal fraction of its true consciousness and power. Its most common M-Body is a giant, robed humanoid figure, but it has taken other forms when necessary.
• Vulnerabilities and Limitations:
• Cosmic-Scale Threats: Despite its immense power, Eternity is not invincible. Beings wielding artifacts of sufficient power, like Thanos with the Infinity Gauntlet, can overpower and even supplant it as the supreme being of reality.
• Extra-Universal Beings: Entities from outside the standard multiverse, such as the Beyonders or the First Firmament, operate on a level of existence beyond Eternity and can capture, manipulate, or even destroy it. During the 2015 Ultimates series, a mysterious entity known as the “Chainer” successfully imprisoned Eternity, causing all of reality to break down.
• Conceptual Corruption: If the universe itself becomes “sick” or corrupted, so does Eternity. In the Cancerverse, where Death was eliminated, the entire universe became a twisted, immortal cancer, and its version of Eternity was similarly corrupted.
• The Law of the Multiverse: Eternity is bound by the decrees of the Living Tribunal and the cosmic balance. It cannot simply act on a whim without risking cosmic imbalance.

The MCU's Eternity is far more limited and defined, functioning as a plot device rather than an active character.

• Core Nature:
• Cosmic Locus: It is a destination, not a being. The “Altar of Eternity” appears to be a pocket dimension or a singular point in spacetime where the foundational power of the universe is accessible.
• Silent and Passive: The MCU Eternity displays no consciousness, personality, or will of its own. It is a neutral force that responds to the request of the first being to arrive, regardless of their morality or the consequences of their wish. It reflects the image of the wisher in its pool before granting the request.
• Powers and Abilities:
• Wish Granting: Its sole demonstrated power is the ability to grant a single, seemingly omnipotent wish. This wish appears to have no limitations. It was capable of fulfilling Gorr's initial desire to “kill all gods,” a feat of universal scale. It was also able to perfectly resurrect Gorr's daughter, Love, seemingly from nothingness, and imbue her with cosmic powers derived from Eternity itself.
• Cosmic Empowerment: A secondary effect of the wish seems to be the empowerment of the subject. Love, upon her resurrection, became a “child of Eternity,” wielding cosmic energy and traveling through space alongside Thor.
• Vulnerabilities and Limitations:
• Accessibility: Its primary limitation is the difficulty in reaching it. It requires the Bifrost and a specific key (like Stormbreaker) to open its gates, making it inaccessible to all but a very select few.
• One-Time Use: The lore strongly implies it is a “first come, first served” system that grants only one wish before presumably becoming dormant again for a time. It is a single-use ultimate weapon.
• Lack of Agency: Its greatest vulnerability is its neutrality. It has no power to refuse a wish, meaning a being with malicious intent like Gorr could have used it to bring about universal destruction without any resistance from Eternity itself. Its power is wielded entirely by the will of others.

As a fundamental cosmic force, Eternity does not have “friends” or “enemies” in the traditional sense. It has counterparts, superiors, subordinates, and existential threats.

• Infinity: Eternity's closest counterpart and “sister” entity. Where Eternity embodies Time, Infinity embodies Space. They are two halves of the same whole, representing the unified space-time continuum of their universe. They are almost always seen together when the cosmic abstracts convene and are equal in power and stature.
• Doctor Strange (The Sorcerer Supreme): Eternity's most significant mortal champion. As the Sorcerer Supreme, Strange's duty is to protect the Earth-616 reality from mystical threats. Since Eternity is that reality, Strange is, by extension, its primary defender. Their relationship is one of a distant god and its high priest. Strange has sought Eternity's counsel, fought to defend its existence, and acted as its agent on numerous occasions.
• The Living Tribunal: Eternity's superior. The Living Tribunal is the cosmic judge of the Multiverse, tasked with maintaining balance across all realities. Eternity, as the embodiment of a single universe, is subject to the Tribunal's judgment. When Thanos assembled the Infinity Gauntlet, Eternity appealed to the Living Tribunal, but the Tribunal decreed that the matter should be resolved within the universe itself unless Thanos threatened the wider Multiverse.

• Thanos: The Mad Titan is the most famous being to have defeated Eternity. During the Infinity Gauntlet saga, Thanos used the combined might of the six Infinity Gems to become the supreme being of reality. He battled the assembled cosmic pantheon and, in a climactic confrontation, defeated Eternity and took its place, becoming the living embodiment of the universe. Eternity was only restored after Nebula seized the Gauntlet from Thanos.
• Dormammu: The ruler of the Dark Dimension represents a constant threat. Dormammu's goal is to absorb all other dimensions and universes into his own, which would mean the utter consumption and destruction of Eternity. Their conflict is a foundational part of Doctor Strange's lore, with Strange acting as the shield that protects Eternity from Dormammu's ambitions.
• The First Firmament / The Chaos King: These represent threats on a scale beyond even that of Thanos. The First Firmament is the sentient first iteration of the universe that seeks to reclaim its shattered parts and end the dynamic multiverse, which would mean subsuming Eternity. Amatsu-Mikaboshi, the Chaos King, was an entity from the primordial void that predated the universe itself. During the Chaos War storyline, he successfully consumed over 98% of the multiverse, effectively killing countless cosmic beings, including Eternity, before being defeated by a god-powered Hercules.

Eternity's appearances are rare and signify events of the highest cosmic magnitude.

This is the foundational storyline that introduced Eternity. To defeat the combined threat of Baron Mordo and Dormammu, Doctor Strange was forced by the Ancient One to seek out a power beyond all others. This sent him on a surreal, dimension-hopping quest across Steve Ditko's psychedelic landscapes. After overcoming numerous trials and proving his worth, Strange finally stood before Eternity. Instead of fighting for him, Eternity judged Strange worthy of its power, allowing the sorcerer to channel a fraction of its might to become powerful enough to defeat his foes. This arc established the entire concept of the Marvel cosmic hierarchy and cemented Strange's role within it.

Perhaps Eternity's most famous role. When Thanos acquires the Infinity Gauntlet and wipes out half of all life in the universe, the surviving heroes and cosmic entities unite to stop him. The cosmic abstracts, led by Eternity, confront Thanos directly. In a stunning display of power, Thanos systematically defeats them all. The final confrontation sees Eternity itself challenge Thanos, but the Gauntlet's power over all aspects of reality—Time, Space, Mind, Soul, Reality, and Power—proves superior. Thanos imprisons Eternity and usurps its position as the nexus of all reality, a moment that stands as one of the most significant defeats of a cosmic entity in Marvel history.

This modern series by Al Ewing redefined Marvel's cosmology. The story begins with the discovery that Eternity is in chains, imprisoned by an unknown cosmic force. This “chaining” is causing reality to break down, with time itself becoming unstable. The Ultimates team (Captain Marvel, Black Panther, Blue Marvel, Spectrum, and America Chavez) transform themselves from planetary defenders into cosmic problem-solvers. Their mission is to diagnose the “illness” of the universe and free Eternity. This quest reveals the history of the previous Cosmos, the nature of the First Firmament, and ultimately positions Galactus in a new role as the “Lifebringer” to heal the cosmic damage. This storyline treated Eternity not just as a deus ex machina but as a central character whose plight drove the entire narrative.

• Marvel Cinematic Universe (Earth-199999): As detailed extensively, this is the most prominent variant. It is not a conscious entity but a location at the center of the universe. It is a passive, wish-granting nexus of power, a stark contrast to the sentient, active, and personified nature of its Earth-616 counterpart.
• Cancerverse (Earth-10011): Featured in The Thanos Imperative, this reality provides a horrifying look at a corrupted Eternity. In this universe, Lord Mar-Vell defeated Death itself, resulting in a universe where nothing could die. Life became a cancerous, unending plague. The entire universe, and by extension its version of Eternity and the other abstracts, became a monstrous, tentacled abomination, part of a collective called the “Many-Angled Ones.” This variant demonstrates that Eternity's nature is fundamentally tied to the cosmic balance of its home reality.
• The Ultimate Universe (Earth-1610): The Ultimate Marvel imprint generally took a more grounded, less metaphysical approach to its universe. The high-level cosmic abstracts like Eternity and the Living Tribunal were largely absent or unmentioned. The cosmology of this universe was less defined, focusing more on threats like Galactus (reimagined as Gah Lak Tus, a swarm of city-sized drones) and the Phoenix Force. The absence of a personified Eternity is itself a defining characteristic of this alternate reality.
