The Eternals first appeared in The Eternals #1, published in July 1976. They were created, written, and drawn by the legendary Jack “The King” Kirby upon his return to Marvel Comics after a stint at rival DC Comics. The series was Kirby's grand-scale exploration of cosmic mythology, ancient astronauts, and the origins of humanity, heavily influenced by popular pseudo-scientific theories of the time, most notably Erich von Däniken's 1968 book Chariots of the Gods?.
Initially, Kirby's The Eternals was not intended to be part of the mainstream Marvel Universe. It was a self-contained epic, allowing Kirby the creative freedom to build a new pantheon of gods without being constrained by existing continuity. However, after the series was canceled after 19 issues and one annual, characters like Ikaris and Sersi were gradually integrated into the wider Marvel continuity through guest appearances in titles like Thor and The Avengers. This integration retroactively established the Celestials' experiments as a cornerstone of Earth's superhuman history, explaining not only the Eternals and Deviants but also the latency of the mutant X-gene in humanity.
The concept was famously revived and modernized in 2006 by writer Neil Gaiman and artist John Romita Jr. in a celebrated miniseries. This series reintroduced the characters to a new generation, adding a layer of mystery and psychological depth by having the Eternals living on Earth with their memories wiped. Most recently, writer Kieron Gillen and artist Esad Ribić have radically redefined the Eternals' lore, introducing dark secrets about their resurrection process that have thrust them into major conflicts like the Judgment Day crossover event.
The origin of the Eternals is a tale of cosmic intervention on a planetary scale. While the core concept of Celestial experimentation is present in both major continuities, the specifics, purpose, and consequences differ dramatically.
Approximately one million years ago, a colossal starship belonging to the space gods known as the Celestials arrived at Earth. This “First Host” of Celestials, led by Arishem the Judge and Gammenon the Gatherer, discovered that the nascent life on the planet had the potential for greatness. They selected a tribe of early proto-humans (Homo erectus) and subjected them to a series of profound genetic experiments. This cosmic tampering resulted in the creation of three distinct offshoots of humanity:
Following their creation, the Eternals established great cities like Olympia in Greece and Polaria in Siberia. They became locked in a perpetual, brutal war with the Deviant empire based in the sunken city of Lemuria. Over millennia, human civilizations witnessed the Eternals' power and beauty, mistaking them for the gods of Greek, Roman, and other mythologies, a misconception the Eternals sometimes encouraged. Their primary directive from the Celestials was to protect the Celestial “process” on Earth, which primarily involved defending the planet from Deviants and awaiting the Celestials' eventual return for judgment. A major modern retcon by Kieron Gillen revealed a horrifying truth behind their immortality: every time an Eternal is resurrected by The Machine, a random human life is consumed to pay the “cost.” This revelation re-contextualizes their role as protectors into something far more parasitic and sinister.
The MCU origin, as detailed in the film Eternals (2021), is a complete reimagining of the comic book lore. In this continuity, the Eternals are not an evolutionary offshoot of humanity. They are entirely artificial beings, synthetic humanoids created by the Prime Celestial, Arishem the Judge, in a cosmic foundry called the World Forge. They are, in essence, highly advanced, immortal androids. Arishem's grand design involves seeding countless planets across the universe with Celestial “eggs” in their cores. For a Celestial to “emerge,” it requires a vast amount of intelligent life energy, which can only be generated by a large, thriving planetary population. However, an apex predator known as the Deviants would invariably evolve on these worlds and consume the intelligent life, preventing the Celestial birth. To solve this problem, Arishem created the Eternals. Their sole, programmed purpose is to be sent to these “seeded” planets to eliminate the Deviants, allowing the native population to flourish and grow. Once the population reaches the required threshold, the Emergence occurs, a new Celestial is born, and the planet is destroyed in the process. The Eternals are then collected, their memories of the previous cycle are wiped clean, and they are sent to a new planet to repeat the process. The Eternals of Earth arrived in 5,000 BC, believing their home planet was Olympia and their mission was simply to protect humanity from Deviants. They spent millennia guiding and protecting human civilization until they believed the last of the Deviants were defeated. They then went their separate ways, awaiting a call from Arishem to return home. However, the impending Emergence of the Celestial Tiamut from Earth's core forces them to reunite and confront the true, genocidal nature of their mission, causing a schism between those loyal to Arishem's plan and those who have grown to love humanity.
The powers of the comic book Eternals are vast, derived from their ability to metabolize and manipulate cosmic energy on a molecular level. While all Eternals share a baseline set of abilities, many choose to specialize in specific disciplines over their long lives.
A unique gestalt entity formed when Eternals join together in a ritual of collective consciousness. The Uni-Mind combines the will, intelligence, and power of all its participants into a single, immensely powerful psionic being of pure energy. It is led by the Prime Eternal and is used to make critical decisions or face threats too great for any single Eternal.
Eternal society is ancient and highly structured. They are led by a Prime Eternal, a title held by figures like Zuras and, later, Ikaris. Their primary cities are Olympia (hidden in the Greek mountains) and the Polar Eternals' city of Polaria in Siberia. Their culture is often depicted as aloof, conservative, and disconnected from the rapidly changing human world they are sworn to protect. A fundamental schism exists between those who wish to remain isolated and those, like Sersi, who actively engage with humanity.

Beyond their own society, the Eternals' primary affiliations have been with superhero teams.

During the Secret Invasion event, Ajak and Makkari were part of Hercules' “God Squad,” a team of divine beings assembled to fight the Skrull gods.
The foundational epic that introduced the world to the Eternals, Deviants, and Celestials. The story revolves around the impending arrival of the Fourth Host of Celestials to Earth to pass judgment on their creations. Archaeologist Dr. Daniel Damian and his daughter Margo stumble upon this hidden war, with Ikaris serving as their guide to a world of gods and monsters. Kirby used the series to build a massive, original mythology, establishing the core tenets of the Eternals' existence, their conflict with the Deviants under Warlord Kro, and the awe-inspiring, silent power of the Celestials.
This landmark miniseries revitalized the franchise for the modern era. The story begins with the Eternals living on Earth as ordinary humans—doctors, party planners, mechanics—with no memory of their true identities. A medical student, Mark Curry (secretly Makkari), begins to uncover the truth after being contacted by Ikaris. The plot reveals that the amnesia was the work of Sprite, who, tired of being a child forever, used the power of the Dreaming Celestial (a dormant Celestial buried beneath San Francisco) to rewrite reality. The series was a critical success, reintroducing the characters with psychological depth and setting the stage for their re-integration into major Marvel events. It also established the critical plot point that “The Machine”—their resurrection device—was broken.
This massive crossover event between the Avengers, X-Men, and Eternals elevated the Eternals to the forefront of the Marvel Universe. With the secret of mutant resurrection on Krakoa revealed to the world, the Prime Eternal Druig declares mutants to be a form of “excess deviation” and launches a genocidal war. To stop the conflict, a group of heroes and rebel Eternals resurrect the Avengers' Celestial base, creating a new, impossibly powerful god, the Progenitor. However, the Progenitor immediately decides to judge every single being on Earth on an individual basis, threatening to destroy the planet if it is found wanting. The event forced the Eternals to confront the dark secret of their resurrection—that it costs a human life each time—and broadcast this truth to the world, shattering their god-like image forever.
