Eternity first materialized in the pages of Strange Tales
#138, published in November 1965. This landmark issue was crafted by the legendary duo of writer Stan Lee and artist Steve Ditko, the architects of Doctor Strange's mystical corner of the Marvel Universe. The creation of Eternity was a direct result of Ditko's and Lee's desire to push the boundaries of conventional comic book storytelling. The mid-1960s were a period of cultural and artistic experimentation, and Ditko's art, in particular, leaned heavily into psychedelic, surreal, and mind-bending visuals.
Eternity was conceived as the ultimate goal in Doctor Strange's epic battle against Baron Mordo and the Dread Dormammu. Instead of a simple physical confrontation, the story became a metaphysical quest. Strange had to prove his worthiness to a series of cosmic gatekeepers before being granted an audience with the embodiment of the universe itself. Ditko's visual design for Eternity—a silent, humanoid silhouette containing the vast starscape of the cosmos—was instantly iconic. It perfectly captured the character's incomprehensible scale and abstract nature, moving beyond the typical depiction of “powerful gods” into something far more conceptual and awe-inspiring. This introduction cemented the Marvel Universe as a place of infinite possibility, where philosophical concepts could be given form and agency, a trend that would define its cosmic landscape for decades to come.
The origin of Eternity is synonymous with the origin of the universe itself. Its history is not one of a character being born, but of a cosmos gaining consciousness.
In the prime Marvel continuity, Eternity came into being with the Big Bang, the singular event that created the current iteration of the universe (known as the Seventh Cosmos, later evolving into the Eighth). At the moment of creation, the primal forces of existence coalesced into sentient forms. Eternity emerged as the personification of time and reality, the collective consciousness of all matter, energy, and life that would ever exist within its domain. Simultaneously, its conceptual counterparts were also born. Its “sister,” Infinity, represents the boundless expanse of space. Together, Eternity and Infinity form the entirety of the space-time continuum. Opposing them were the entities of Death, the end of all things, and Oblivion, the void of non-existence. These four beings form the “Cosmic Compass,” representing the fundamental pillars of reality. Eternity is not a being that lives in the universe; it is the universe. Every star, planet, and living creature is a part of its whole. When a being dies, they leave Eternity's embrace and enter the realm of Death. Its health is directly tied to the well-being of the universe. When cosmic cancers like the Cancerverse emerge or when reality is threatened by beings like the Beyonder or a Thanos wielding the Infinity Gauntlet, Eternity itself is wounded, captured, or even “killed.” Over the eons, it has been a largely passive observer, allowing life to evolve and events to transpire according to the laws of physics and fate. It only manifests or allows itself to be contacted when the fundamental nature of its existence is threatened. In Al Ewing's acclaimed run on The Ultimates, it was revealed that previous iterations of the multiverse (or “Cosmos”) had their own equivalent of Eternity. It was also shown that the Eternity of the Seventh Cosmos had been “chained” by a cosmic parasite, the First Firmament, which limited its evolution. The Ultimates' actions freed Eternity, allowing it to evolve into the Eighth Cosmos's more complex and proactive form.
The MCU's interpretation of Eternity, primarily seen in Thor: Love and Thunder
, is a significant departure from the comics' abstract concept, adapted for a more direct cinematic narrative. In this continuity, Eternity is not explicitly the sentient universe itself but is instead a mysterious and ancient entity residing at a physical, albeit mystical, location known as the Gates of Eternity, situated at the “Center of the Universe.”
This location is presented as a destination, a cosmic nexus that can only be reached using the Bifrost. According to legend, the first person to reach its altar will be granted a single wish, capable of altering reality in any way they see fit. This reframes Eternity from a passive, all-encompassing consciousness into an active plot device—a cosmic “genie” of sorts. Gorr the God Butcher seeks to reach Eternity to wish for the death of all gods, while Thor and Jane Foster (The Mighty Thor) race to stop him.
Visually, when Gorr arrives, he enters a serene, watery dimension where a silent, star-filled silhouette (visually homologous to its comic counterpart) awaits. After Thor convinces Gorr to choose love over vengeance, Gorr wishes for his daughter, Love, to be brought back to life. Eternity grants this wish, and as Gorr dies, he entrusts his resurrected daughter to Thor's care. Love is shown to be imbued with cosmic powers, presumably as a result of her “birth” at the hands of Eternity.
This adaptation serves a clear narrative purpose: it provides a tangible goal for the film's villain and a mechanism for the film's resolution. It simplifies the impossibly vast concept of the comic's Eternity into a more understandable and character-driven MacGuffin, while still paying visual homage to its iconic Ditko design. A brief, non-sentient glimpse of Eternity's form was also seen by Star-Lord during his celestial awakening in Guardians of the Galaxy Vol. 2
.
Eternity's abilities and very essence are defined by its status as the universe personified. Its power is near-absolute but is constrained by the very laws of reality it embodies.
Eternity is a functionally omniscient and omnipresent abstract entity. It is aware of everything that happens within the universe simultaneously, from the grandest cosmic battles to the smallest subatomic interactions. However, its consciousness is so vast and alien that it perceives reality on a scale incomprehensible to mortal minds. It does not think in terms of good or evil, but in terms of balance, existence, and survival. It is typically a reactive force, only taking action or seeking champions when the universe's fundamental structure is at risk.
As the embodiment of all of time and space, Eternity is one of the most powerful beings in existence, surpassed only by multiversal entities like the Living Tribunal and the ultimate creator, the One-Above-All.
Despite its immense power, Eternity is not invincible. Its primary weaknesses stem from its nature:
The MCU's Eternity is far less defined, with its nature and powers observed only through the lens of the events in Thor: Love and Thunder
.
In the MCU, Eternity appears to be a non-communicative, passive entity. It does not speak or offer counsel; it simply waits at the Center of the Universe to grant a wish. Its consciousness, if it exists in a form similar to the comics, is not explored. It functions more like a fundamental force of nature or a magical mechanism than a sentient character. It is a place of power, a final destination.
The core difference is one of agency versus function. The comic book Eternity is an agent—a character, however abstract, with a will and a role in the cosmic drama. The MCU Eternity is a function—a plot device that provides a solution to the film's central conflict. This change streamlines a complex piece of lore for a general audience, transforming an existential concept into a tangible, goal-oriented quest.
As a fundamental force of the universe, Eternity's relationships are with other cosmic entities who define the nature of existence.
Eternity's “enemies” are typically beings or forces that seek to subvert, consume, or destroy the universe it embodies.
Eternity's appearances are rare but always signify events of universe-altering importance.
This is the quintessential Eternity story and its introduction to the Marvel Universe. Pursued relentlessly by Baron Mordo and the nigh-unstoppable Dormammu, a desperate Doctor Strange learns of a final, ultimate power he can appeal to: Eternity. Guided by the Ancient One, Strange embarks on a perilous journey through bizarre, hostile dimensions, facing surreal trials to prove his worth. The climax sees Strange finally reach Eternity. Instead of fighting Strange's battle for him, Eternity simply bestows upon Strange a fraction of its power and the authority to defeat Dormammu, establishing his role as a champion of reality and Eternity's chosen mortal representative.
During this 1991 epic, a nihilistic Thanos, seeking to win the affection of Mistress Death, assembles the six Infinity Gems. With godlike power, he defeats Earth's heroes and challenges the cosmic pantheon itself. In a now-famous sequence, the most powerful cosmic beings, led by Eternity, confront Thanos. The battle is short and decisive. Thanos, wielding the full power of the Gauntlet, effortlessly imprisons them all. He then ascends to a higher plane of existence, leaving his physical body behind to become the living embodiment of the universe, supplanting Eternity. Eternity remains trapped until Thanos is eventually tricked by Nebula and defeated by Adam Warlock. This storyline cemented just how powerful the Gauntlet was, as it was able to defeat the universe itself.
In Al Ewing's modern cosmic saga, the super-team known as The Ultimates (including Captain Marvel, Black Panther, and Galactus, the Lifebringer) takes on the mission of solving cosmic-level problems. They discover that Eternity has been “chained” and imprisoned by an ancient cosmic predator, the First Firmament. This event, known as the Eternity War, sees the pantheon of the current (Eighth) Cosmos battle the Aspirant gods of the First Firmament. The Ultimates manage to free Eternity, who evolves and helps defeat the ancient threat. This story fundamentally updated Eternity's lore, introducing the concept of multiversal evolution and giving the entity a more active and personal role in its own preservation.
As the embodiment of a single universe, every alternate reality in the Marvel multiverse technically has its own version of Eternity.
