The universe of Marvel is vast, populated by street-level heroes like Spider-Man and galactic defenders like the Guardians of the Galaxy. However, hidden within the cracks of human history lies a group of beings far older and more complex than almost any other faction in the Marvel mythos: the Eternals. Created by the legendary artist Jack Kirby, these immortal beings represent a unique intersection of science fiction, ancient mythology, and high-concept cosmic horror. Whether you know them from the 2021 blockbuster film directed by Chloé Zhao or from the dense, psychedelic pages of 1970s comic books, understanding the Eternals requires a journey back through millions of years of fictional history and decades of real-world creative evolution.

The Genesis of an Immortal Race

The story of the Eternals begins not in the stars, but in the creative mind of Jack "The King" Kirby. In 1970, Kirby famously left Marvel Comics for its rival, DC Comics, where he created the "Fourth World" saga and the New Gods. When that project was prematurely ended, Kirby returned to Marvel in the mid-70s with a head full of ideas regarding ancient astronauts, hidden gods, and the evolutionary potential of humanity.

In July 1976, The Eternals #1 introduced a world where humanity was not the only intelligent life on Earth. Kirby proposed that a million years ago, god-like alien entities known as the Celestials visited Earth to perform genetic experiments on proto-humans. This experimentation resulted in three distinct branches of the human tree:

  1. The Eternals: A long-lived, powerful, and beautiful race of "Homo immortalis."
  2. The Deviants: A genetically unstable, monstrous, and constantly mutating race.
  3. Humanity: The "baseline" species, gifted with the latent potential for superpower mutation (which would later explain the existence of Mutants and X-Men).

Kirby’s original vision was intended to be separate from the main Marvel continuity, functioning more as a standalone epic about the return of "gods" to Earth. However, over time, the Eternals were integrated into the broader Marvel Universe, interacting with the Avengers, the X-Men, and the cosmic hierarchy.

The Celestial Architects and the Deviant Threat

At the heart of the Eternals' existence are the Celestials. These towering, silent titans in multicolored armor are the ultimate gardeners of the cosmos. Led by figures like Arishem the Judge and Eson the Searcher, the Celestials travel from planet to planet, seeding life and then returning millennia later to judge whether that life is worthy of continued existence.

The Eternals were tasked with a singular, eternal mission: to protect humanity from the Deviants. In the comics, the Deviants established a massive undersea empire called Lemuria and viewed themselves as the rightful rulers of Earth. Their unstable DNA meant that no two Deviants looked alike, leading to a culture that deified physical strength and shunned "perfection." The conflict between the god-like Eternals and the demon-like Deviants formed the basis for many human myths and legends, from the Greek gods of Olympus to the stories of angels and fallen demons.

Key Members of the Eternal Collective

Unlike many superhero teams, the Eternals are a society. While there are hundreds of them across the globe (and on other planets like Titan and Uranus), a core group of ten has become the face of the franchise for modern audiences. Each member possesses the ability to manipulate cosmic energy, but most choose to specialize in one specific discipline.

Sersi the Transmuter

Sersi is perhaps the most famous Eternal in comic book history, largely due to her long tenure as a member of the Avengers in the 1990s. Unlike her brothers and sisters who prefer isolation, Sersi loves humanity. She thrives in the social circles of New York City and London, working as an entertainer and socialite. Her primary power is molecular transmutation—the ability to change the physical structure of matter. In the 2021 film, portrayed by Gemma Chan, she is the emotional core of the story, showing a level of empathy for humans that eventually leads her to defy her creators.

Ikaris the Prime Candidate

Ikaris is the archetypal superhero of the group. Often compared to Superman due to his ability to fly and fire cosmic beams from his eyes, Ikaris is defined by his unwavering loyalty to the Celestial mission. In the comics, he is often the "Prime Eternal," the leader of the group. His name is a direct reference to the myth of Icarus, though in the Marvel Universe, the myth is said to be based on Ikaris’s own son. His rigid adherence to duty often puts him at odds with the more rebellious members of his race.

Thena the Warrior

Thena, the daughter of the original Eternal leader Zuras, is a master of combat and weaponry. She can manifest any weapon she imagines out of pure cosmic energy. In both the comics and the film (played by Angelina Jolie), she is portrayed as a tragic figure. In the MCU, she suffers from "Mahd Wy’ry," a psychological condition where an Eternal’s mind collapses under the weight of thousands of years of memories, causing her to lash out at allies and enemies alike.

Ajak the Spiritual Leader

In the original comics, Ajak was a male warrior who served as the primary link between the Eternals and the Celestials. The MCU reimagined the character as a female leader and maternal figure, portrayed by Salma Hayek. Ajak possesses healing powers and is the only one capable of communicating directly with Arishem the Judge. This role as a "prophet" places a heavy burden on the character, as she is often the only one who knows the true, darker purpose of their presence on Earth.

Kingo the Performer

Kingo represents the intersection of the Eternals' immortality and human culture. In the comics, he spent centuries in Japan, becoming a master samurai and eventually a movie star who specialized in samurai films. The MCU updated this by making him a Bollywood superstar, played by Kumail Nanjiani. Kingo specializes in projecting cosmic energy projectiles from his hands, but his real contribution to the team is his unique perspective on how to live a meaningful life among mortals.

Phastos the Inventor

Phastos is the technological genius of the Eternals. He is responsible for much of the advancement in human civilization, though he often struggles with the consequences of his inventions. In the MCU, this is highlighted through his grief over the development of the atomic bomb. His ability to manipulate cosmic energy to create complex machinery makes him the "engineer" of the team, capable of building anything from starships to the Uni-Mind interface.

Makkari the Speedster

Makkari is the fastest being in the Marvel Universe, often competing with Quicksilver or the Runner for the title. In the comics, Makkari was an inventor obsessed with speed. The MCU made the character female and deaf, portrayed by Lauren Ridloff, which allowed for a visually stunning representation of superspeed that focuses on sonic booms and vibrations. Her speed is so great that she can traverse the entire planet in minutes, making her the team's primary scout.

Druig the Mind-Controller

Druig is the "black sheep" of the Eternals. While others want to protect or live among humans, Druig often views them with disdain or as subjects to be controlled. His power of mind manipulation allows him to command entire populations. In the 2021 film, he is portrayed by Barry Keoghan as a disillusioned pacifist who uses his powers to force humans into a state of artificial peace, raising complex ethical questions about free will.

Gilgamesh the Strong

The strongest of the Eternals, Gilgamesh has been known by many names throughout history, including Hercules (though he is distinct from the Marvel character of that name) and Beowulf. In the MCU, played by Don Lee, he is the protector of Thena, choosing to live in isolation with her to help manage her Mahd Wy’ry. His immense physical strength is augmented by a cosmic exoskeleton he can manifest around his fists.

Sprite the Illusionist

Sprite is an Eternal trapped in the body of a twelve-year-old child. While physically young, Sprite is thousands of years old and is a master of illusions. This duality creates a deep-seated resentment in the character, as they are never allowed to experience the complexities of adult human life. This tragedy drives Sprite to make several questionable choices in both the 2006 Neil Gaiman comic run and the 2021 film.

The Uni-Mind: The Peak of Eternal Power

One of the most unique aspects of Eternal biology is the Uni-Mind. When the situation becomes dire, the Eternals can perform a ritual that merges their physical and mental forms into a single, massive, glowing entity of pure intellect and cosmic power.

The Uni-Mind requires at least seven Eternals to initiate. It is not just a physical weapon but a democratic collective where the wills of all participants are joined. In the comics, the Uni-Mind is often used to make major decisions for the race or to communicate with the Celestials. In the MCU, Phastos adapts the concept of the Uni-Mind into a technological link that allows the team to pool their cosmic energy into one individual (Sersi) to perform an act of near-impossible transmutation.

Comparing the Comic Canon to the MCU

While the 2021 film stays true to the spirit of Jack Kirby’s work, it introduces several significant departures from the comic book lore.

Synthetic vs. Biological

In the original comics, the Eternals are biological beings—an offshoot of humanity. They can have children (though it is rare) and are subject to biological evolution to some degree. In the MCU, the film reveals a massive plot twist: the Eternals are actually advanced synthetic beings, essentially "cosmic robots" created in a place called the World Forge. They do not age, and their memories are "reset" by the Celestials after every mission.

The Purpose of the Emergence

The biggest narrative shift in the film concerns the "Emergence." In the MCU, the Eternals were sent to Earth to ensure the human population grew large enough so that their collective life energy could fuel the birth of a new Celestial, Tiamut, growing inside the Earth's core. This birth would inevitably destroy the planet. This adds a layer of cosmic horror and moral ambiguity that wasn't present in Kirby's original run, where the Eternals were genuinely meant to be the benevolent protectors of mankind.

The Role of the Deviants

In the comics, the Deviants are a sentient society with their own politics, religion, and culture. In the MCU, they are portrayed more as "apex predators" gone wrong—biological tools created by the Celestials to clear a path for intelligent life, which then evolved and became uncontrollable.

The Modern Revival: Neil Gaiman and Kieron Gillen

The Eternals have seen several major revivals in the comics that have reshaped their role in the Marvel Universe.

In 2006, acclaimed novelist Neil Gaiman teamed up with artist John Romita Jr. to bring the Eternals into the modern era. In this story, the Eternals have had their memories wiped and are living as normal humans, unaware of their god-like status. Ikaris is the first to "wake up" and must find his teammates before the Deviants find them. This run was highly influential on the MCU film, particularly the concept of the Eternals living hidden among us.

In 2021, writer Kieron Gillen and artist Esad Ribić launched a new Eternals series that tackled the darker side of their immortality. This run introduced the idea that every time an Eternal is resurrected by the "Great Machine" (the Earth itself), a human life must be sacrificed. This revelation forced the characters to reckon with the cost of their existence and eventually led to the A.X.E.: Judgment Day crossover event, where the Eternals, the Avengers, and the X-Men faced off against a Celestial that had deemed the Earth unworthy of survival.

The Future of the Eternals in Popular Culture

The introduction of the Eternals has permanently expanded the scope of the Marvel Cinematic Universe. With the introduction of characters like Starfox (Eros of Titan, played by Harry Styles) and the looming threat of Arishem the Judge, the cosmic side of the MCU is set for a major collision.

In the comics, the Eternals continue to be a bridge between the mythological past and the sci-fi future. They serve as a reminder that in a world of super-soldiers and billionaire inventors, there are forces that have been watching us since the dawn of time—beings who view the rise and fall of empires as mere blips in an infinite timeline.

Whether as Jack Kirby’s "Return of the Gods" or Chloé Zhao’s "Found Family," the Eternals represent our fascination with the divine and our hope that, even in the face of cosmic indifference, there are those who will choose to protect the humanity they have come to love.

Summary of the Eternals Lore

The Eternals are an essential part of the Marvel tapestry, representing the highest stakes of cosmic storytelling. From their creation as the "Homo immortalis" to their struggle against their own creators, the Celestials, they provide a philosophical lens through which we can view the Marvel Universe. They are not just heroes; they are living history, the guardians of the evolutionary spark, and the silent watchers of our world.

Frequently Asked Questions about the Eternals

What are the main powers of the Eternals?

All Eternals possess superhuman strength, durability, and the ability to manipulate cosmic energy. Common powers include flight, molecular transmutation, energy projection, and telepathy. However, most Eternals choose to focus their training on one specific power, such as Makkari’s speed or Phastos’s technological creation.

Who created the Eternals in the Marvel Universe?

Within the story, the Eternals were created by the Celestials—enormous, god-like aliens. In the real world, the characters were created by Jack Kirby, first appearing in The Eternals #1 in 1976.

Are the Eternals stronger than the Avengers?

Individually, many Eternals are more powerful than the average Avenger due to their immortality and cosmic energy. However, the Avengers have a greater diversity of powers and experience in teamwork. In the comics, the two groups have clashed and collaborated many times, with characters like Sersi and Gilgamesh even serving as members of both teams.

Is Thanos an Eternal?

In the comic books, yes. Thanos is a member of the Eternals of Titan. He was born with "Deviant Syndrome," which explains his purple skin and monstrous appearance compared to his brother, Eros (Starfox). In the MCU, this connection is hinted at in the post-credits scene of the 2021 film but has not been as explicitly detailed as in the comics.

What is the relationship between the Eternals and the Deviants?

The Eternals and Deviants are evolutionary cousins, both created by the Celestials. They have been at war for millions of years. While Eternals represent stability and "perfection," Deviants represent change and "instability." This conflict is the source of many human legends about the war between gods and demons.
