Eternals (Race)

• Core Identity: The Eternals are a super-powered, near-immortal offshoot of humanity, bio-engineered by the cosmic god-like Celestials to serve as Earth's designated protectors and cultivators.
• Key Takeaways:
• Role in the Universe: Originally conceived as planetary defenders against their monstrous counterparts, the Deviants, their true purpose is to cultivate intelligent life on a planet until it reaches a population sufficient to trigger the birth of a new Celestial from the planet's core, an event which destroys the planet itself. jack_kirby.
• Primary Impact: For millennia, the Eternals operated from the shadows, their existence giving rise to humanity's myths of gods and heroes. Their recent re-emergence and the revelation of their true purpose have positioned them as a major cosmic power, often placing them in direct conflict with Earth's heroes like the avengers and the x-men.
• Key Incarnations: In the Earth-616 comics, they are an evolutionary offshoot of humanity, capable of biological reproduction and resurrection through a complex “Machine.” In the Marvel Cinematic Universe, they are synthetic, android-like beings created by the Celestial Arishem, unable to reproduce and programmed with false memories to ensure they fulfill their mission.

The Eternals were created by the legendary writer and artist Jack “The King” Kirby upon his return to Marvel Comics in the mid-1970s. They first appeared in The Eternals #1, published in July 1976. Kirby's creation was a grand, cosmic epic, deeply influenced by the popular “ancient astronauts” theories of the era, most notably Erich von Däniken's Chariots of the Gods?. The core concept proposed that Earth's myths, legends, and technological leaps were not the product of human imagination or evolution alone, but were influenced by extraterrestrial visitors. Kirby envisioned the Eternals, Deviants, and Celestials as his own pantheon, a self-contained mythology separate from the established Marvel Universe. The initial series was written and drawn entirely by Kirby and ran for 19 issues and one annual before its cancellation in 1978, leaving many plotlines unresolved. Despite this, the characters and concepts were too compelling to remain dormant. Writers like Roy Thomas and Mark Gruenwald later integrated the Eternals into the broader Marvel continuity, establishing connections to characters like the Asgardians, Olympians, and even the Kree. The race saw a major revitalization in 2006 with a seven-issue miniseries written by acclaimed author Neil Gaiman and penciled by John Romita Jr. This series served as a major reintroduction for a modern audience, positing that the Eternals had been memory-wiped and were living mundane human lives, slowly reawakening to their true nature. This storyline heavily influenced the 2021 MCU film adaptation and set the stage for the Eternals' more prominent role in 21st-century Marvel comics, culminating in their central involvement in the 2022 crossover event, Judgment Day.

The origin of the Eternals is a tale of cosmic experimentation and divine intervention, but the specifics differ dramatically between the primary comic book universe and the cinematic adaptation. Understanding these differences is crucial to understanding the race itself.

Approximately one million years ago, a colossal starship belonging to the space gods known as the Celestials arrived on Earth. This event, known as the coming of the First Host, marked a pivotal moment in the planet's history. The Celestials, cosmic gardeners of a sort, saw potential in the planet's nascent dominant species, a precursor to Homo sapiens. Led by the Celestials Arishem the Judge and Nezarr the Calculator, the First Host conducted a series of genetic experiments on this proto-humanity. This tampering resulted in the creation of three distinct subspecies from the common ancestral stock:

• The Eternals (Homo immortalis): Beings of immense power and longevity. They were imbued with the ability to process and manipulate cosmic energy on a molecular level. The Celestials designed them to be beautiful, orderly, and powerful—the designated protectors and shepherds of the planet. They were functionally immortal, living for millennia and capable of being resurrected even from total atomic dispersal through a planetary network known as “The Machine.”
• The Deviants (Homo descendus): The chaotic and unstable counterparts to the Eternals. The Deviant genetic code was highly mutable, resulting in a species with no two individuals looking alike, often with monstrous and grotesque appearances. This instability, or “excess deviation,” was considered a failure by the Celestials. They were created as a chaotic force, a genetic “chaff” to the Eternals' “wheat,” and their inherent nature drove them into an endless, brutal conflict with their immortal cousins.
• Baseline Humanity (Homo sapiens): The majority of the proto-humans were left largely unaltered, but a key latent gene was embedded in their DNA. This gene, often called the “X-Gene factor,” would eventually allow for the natural emergence of super-powered individuals, or mutants, effectively turning humanity into a self-powering defense system for the planet.

Following their creation, the Eternals established magnificent cities like Olympia in Greece and Polaria in Siberia. They largely withdrew from human affairs, their occasional appearances inspiring tales of the Greek, Roman, and Norse gods. Their primary directive from the Celestials was to “correct excess deviation,” which translated into a perpetual war against the Deviants who sought to enslave humanity. This charge was to be carried out while awaiting the return of the Celestials for judgment. The Eternals' society was governed by a Prime Eternal, a role most often held by Zuras or his daughter, Thena. A key aspect of their existence is the Uni-Mind, a collective psionic entity formed when a group of Eternals merge their consciousness and physical forms, creating a being of immense power and intellect used for monumental tasks.

The MCU, as detailed in the film Eternals (2021), presents a radically different and more tragic origin. In this continuity, the Eternals are not a product of evolution but are entirely artificial beings. They are highly advanced synthetic constructs, akin to androids, created by the Prime Celestial, Arishem the Judge, within a cosmic foundry known as the World Forge. Arishem's grand design involves the “Emergence” of new Celestials. Celestials are born from the core of specific planets, gestating for eons by feeding on the energy generated by the planet's intelligent life. To facilitate this, Arishem created the Eternals and the Deviants. The Deviants were originally intended to be a predator species sent to planets to eliminate the apex predators, thus allowing intelligent life (like humanity) to flourish unhindered. However, the Deviants evolved beyond their programming, becoming predators of the very life they were meant to protect. To “correct” this flaw, Arishem created the Eternals. These ten beings—Ajak, Sersi, Ikaris, Kingo, Sprite, Phastos, Makkari, Druig, Gilgamesh, and Thena—were dispatched to Earth in 5,000 BC. Their stated mission was to eradicate the Deviants and protect humanity, a task they believed they were performing for countless worlds before. They were programmed with false memories of a home world, Olympia, that never existed. Their true purpose, known only to their Prime Eternal Ajak (and later Sersi), was to ensure humanity's population grew large enough to trigger the Emergence of the Celestial Tiamut from Earth's core. This event would provide the energy necessary to create new stars and galaxies but would utterly obliterate Earth and all life on it. Upon completion of their mission, their memories would be wiped clean at the World Forge, and they would be reassigned to a new planet to begin the cycle anew. This fundamental lie—that they were protectors when they were in fact facilitators of planetary destruction—forms the central conflict of their story in the MCU.

The nature of an Eternal's power and body is a direct result of their unique origins, which again diverge significantly between the two main continuities.

An Eternal's body is a living crucible of cosmic energy. While biologically descended from proto-humanity, their physiology has been fundamentally altered. Every cell in their body is saturated with cosmic power, granting them a level of control over their own atomic structure that is beyond comprehension.

• Immortality and Durability: Eternals do not age past physical maturity and are immune to all terrestrial diseases, toxins, and conventional injuries. While they can be “killed” through catastrophic injury (e.g., molecular dispersal), their consciousness is automatically uploaded to The Machine, a sentient, planet-spanning computer system that serves as the Earth itself. The Machine can then regenerate or “resurrect” any fallen Eternal in a new body from one of the Exclusion chambers. This process has recently been revealed to have a terrible cost: each resurrection requires the expenditure of a random human life.
• The Uni-Mind: A core cultural and physiological practice. By joining hands in a specific ritual, Eternals can merge their minds and bodies into a single, powerful psionic gestalt. The Uni-Mind is pure energy and intellect, capable of making decisions and wielding power on a scale no single Eternal could achieve.

All Eternals share a baseline set of powers derived from their ability to manipulate cosmic energy. However, most choose to specialize in honing a few specific abilities to a level of mastery.

• Shared Powers:
  • Superhuman Strength, Speed, Stamina, and Reflexes: While varying between individuals, all Eternals are far stronger and faster than the finest human athlete.
  • Flight: By psionically manipulating gravitons, they can levitate and fly at supersonic speeds.
  • Psionics: All Eternals possess some degree of telepathy and telekinesis, though some, like Sersi, are more adept than others. They can read minds, project their thoughts, and move objects with their minds.
• Specialized Disciplines:
  • Cosmic Energy Projection: The ability to project beams of raw force, heat, or light from their hands or eyes. Ikaris is the most powerful practitioner of this, able to generate optic blasts of immense destructive force.
  • Matter Transmutation: The power to rearrange the atomic and molecular structure of matter. This is the signature ability of Sersi, who is the most skilled transmuter among all Eternals, capable of turning a skyscraper into dust or transforming a living being into an inanimate object.
  • Illusion Casting: The ability to create complex and convincing illusions by manipulating psionic energy to affect the senses of others. Sprite, who is physically trapped in the body of a child, is the master illusionist.
  • Technopathy and Creation: The ability to mentally interface with and design complex machinery. Phastos is the master smith and engineer of the Eternals, capable of creating unimaginable technologies.
  • Mind Control: The power to psionically dominate the minds of others. Druig is the foremost expert, capable of controlling entire cities of people with a thought.

MCU Eternals are synthetic beings, not biological. Their bodies are constructed from cosmic energy by Arishem and are incredibly durable, but they are not truly “alive” in the traditional sense. They do not eat, sleep, or reproduce. They can be damaged and “killed,” at which point their memories and core programming can be retrieved and placed into a new body at the World Forge. Their bodies are powered by an internal source of cosmic energy, which is channeled to manifest their unique abilities.

Unlike the comics where powers are a matter of discipline, each MCU Eternal is specifically programmed with a single, unique superpower. Their power is visually represented by golden, geometric energy patterns. The ten Eternals and their designated powers are:

A key difference is the source of their power. In the comics, their power is inherent. In the MCU, their power is drawn from the same cosmic energy source that fuels the Celestial Emergence, connecting them directly to their creator and their grim purpose.

• Humanity: In both continuities, the Eternals' primary function is linked to humanity. In the comics, they are its sworn protectors, viewing humans as their younger cousins and defending them from Deviant threats and cosmic judgment. In the MCU, their relationship is more complex; they are tasked with nurturing humanity for slaughter, but many, like Sersi and Phastos, grow to love humans and ultimately defy their programming to save them.
• The Avengers: The Eternals have had a sporadic but significant relationship with Earth's Mightiest Heroes. Sersi served as a prominent member of the Avengers for a time in the 1990s. More recently, during the Judgment Day event, the Eternals' war against the mutants of Krakoa forced a massive conflict with the Avengers, who fought to protect the planet from the Eternals' newly-unleashed divine judgment.
• Thor and the Asgardians: Due to their similar nature as “gods” who walk the Earth, the Eternals have often been compared to and have interacted with the Asgardians. In some retcons, it has been suggested that the Eternal Zuras and the Olympian Zeus are so similar that humans often confused the two, leading to a pact of non-interference between their respective pantheons.

• The Deviants: The ultimate adversaries. In the comics, they are a genetically unstable race driven by chaos and a desire to conquer and enslave humanity. The war between the Eternals and Deviants has raged for a million years. Their leader is often Warlord Kro, who has had a complex, on-again-off-again relationship with the Eternal Thena. In the MCU, the Deviants are failed creations of Arishem, monsters who evolved beyond their programming and hunt intelligent life, including their creators.
• The Celestials: A profound irony defines this relationship. The Celestials are the Eternals' creators, their “gods,” and the source of their power and purpose. However, they are also their greatest threat. The Celestials' cycle of planetary judgment and “harvest” is an existential threat to all life on Earth. The Eternals' struggle is often one of faith versus morality: obey the divine will of their creators or protect the mortal lives they have come to value.
• Thanos the Mad Titan: While not a “true” Eternal, Thanos is their most infamous descendant. Born on Saturn's moon of Titan to an Eternal colony, Thanos carries the “Deviant Syndrome,” which accounts for his grotesque appearance and immense power. His nihilistic obsession with death and cosmic balance makes him an enemy of all life, and the Eternals view him as a perversion of their kind.

The Eternals' primary affiliation is to their own race. They operate as a sovereign nation with their own laws (The Three Principles), culture, and leadership (the Prime Eternal). However, individual Eternals have forged other allegiances. As mentioned, Sersi was a long-serving Avenger. Gilgamesh, also known as The Forgotten One, has adventured alongside Hercules and other heroes. In the modern era, the Eternals have had to act as a unified political and military force on the global stage, interacting with nations like Krakoa and organizations like the avengers.

Jack Kirby's original saga introduced the core concepts. The story begins with the arrival of the Fourth Host of the Celestials, who have come to Earth to pass judgment on their grand experiment. Their silent, colossal presence incites panic across the globe. The narrative follows Ikaris as he works to reawaken humanity to the existence of the Eternals and prepare for the Celestials' verdict. This series established the fundamental conflict between the orderly Eternals and the monstrous Deviants, introduced the Uni-Mind, and set the stage for the cosmic scale of their mythology.

Neil Gaiman and John Romita Jr.'s influential miniseries provided a modern entry point for the race. The story opens with Mark Curry (secretly the Eternal Makkari) experiencing strange dreams of ancient gods and monsters. It's revealed that a former Eternal, Sprite, frustrated with being forever a child, used the power of the Dreaming Celestial to alter reality, wiping the memories of all 100 Eternals and casting them into ordinary human lives. The series follows their gradual and often traumatic reawakening as they rediscover their powers, their history, and the looming threat of the Dreaming Celestial buried beneath San Francisco. This storyline's “sleeper agent” premise was a direct and powerful influence on the MCU film adaptation.

This massive crossover event between the Avengers, X-Men, and Eternals elevated the race to a new level of importance and menace in the Marvel Universe. Following a revelation that mutants are a form of “excess deviation,” the new Prime Eternal, Druig, declares war on the mutant nation of Krakoa, unleashing god-like weapons to eradicate them. This act brings the Eternals into direct conflict with the Avengers and X-Men. The ensuing war awakens the Progenitor, a new Celestial formed from the corpse of the First Host, which now serves as Avengers Mountain. The Progenitor decides to judge the entire planet, giving every individual 24 hours to justify their existence or face total annihilation. This event fundamentally redefined the Eternals' purpose, casting them not as simple protectors but as agents of a terrifying cosmic process.

• Marvel Cinematic Universe (Earth-199999): As detailed extensively above, this is the most prominent alternate version. They are synthetic beings, programmed with a false purpose to facilitate planetary destruction for the birth of new Celestials, a stark contrast to their organic, evolutionary origins in the comics.
• Ultimate Universe (Earth-1610): In this continuity, the Eternals are a more ancient and interventionist race who genetically engineered Homo sapiens millions of years ago. They see humanity as their creation and feel they have the right to cull or control it, viewing super-powered humans (mutants) as a threat to their plan. They served as heralds for the cosmic entity Gah Lak Tus.
• Heroes Reborn (2021): In this alternate reality created by Mephisto where the Avengers never formed, the Eternals are depicted as cosmic parasites. They travel from world to world, masquerading as gods and saviors, only to drain the planet of its life force to sustain their own immortality before moving on to the next victim.
