Deviants (Race)

• Core Identity: The Deviants are a genetically unstable, monstrously diverse offshoot of humanity, engineered by the cosmic Celestials as a counterpart to the god-like Eternals, forever locked in a tragic cycle of mutation, societal strife, and war against their perfect brethren.
• Key Takeaways:
• Role in the Universe: The Deviants serve as a dark mirror to the Eternals, representing the chaotic, unpredictable, and often horrific potential of the Celestials' genetic tampering. Their subterranean empire of Lemuria has plotted the downfall of surface-dwelling humanity and their eternal enemies for millennia.
• Primary Impact: Their greatest impact is their perpetual war with the Eternals, a conflict that has shaped ancient history and occasionally spills over to threaten all of humanity. Their worship and attempted manipulation of the Dreaming Celestial represent one of the most significant cosmic threats to Earth.
• Key Incarnations: In the comics (Earth-616), they are an ancient, technologically advanced civilization with a complex, caste-based society. In the Marvel Cinematic Universe, they are reimagined as feral, bio-engineered predators created to clear planets of apex predators, who later evolve sentience and seek revenge on their creators.

The Deviants, along with their eternal adversaries, were conceived by the legendary “King of Comics,” Jack Kirby, upon his return to Marvel Comics in the mid-1970s. They made their first appearance in The Eternals #1, published in July 1976. This series was a canvas for Kirby to explore epic, mythological themes on a cosmic scale, similar to his “Fourth World” saga at DC Comics. Deeply influenced by Erich von Däniken's popular pseudoscientific book Chariots of the Gods?, Kirby envisioned a secret history of Earth where god-like aliens (the Celestials) visited in the distant past and experimented on early humanity. From this premise, he created three distinct races: the god-like Eternals, the monstrous Deviants, and baseline Humanity, which carried the latent potential for mutation (eventually leading to the X-gene). The Deviants were Kirby's personification of chaos, genetic entropy, and the “demons” or “monsters” of ancient myths, designed as the perfect visual and thematic foils for the serene, beautiful, and unchanging Eternals, who represented the “gods” of those same legends.

The origin of the Deviant race is inextricably linked to the grand cosmic experiments of the god-like Celestials. While their genesis is the same in both the comic and cinematic universes, the nature and purpose of their creation are profoundly different.

Approximately one million years ago, the First Host of the Celestials arrived on Earth. These silent, colossal space gods conducted a series of genetic experiments on the planet's dominant intelligent life form, primitive proto-humans. From this single genetic stock, they engineered three distinct subspecies:

• The Eternals: Beings of cosmic power, granted perfect, unchanging bodies and near-immortality. They were designed to be Earth's protectors.
• The Deviants: Beings whose genetic code was deliberately left unstable. This “Deviant gene” ensures that every member of the race is born with a unique and often grotesque physical mutation, giving them their moniker, the “Changing People.” This instability was intended as an experiment to accelerate evolution and observe the outer limits of genetic plasticity.
• Baseline Humanity: Left largely as a control group, but with latent genetic potential for superhuman evolution, which would later manifest as mutants, Inhumans, and other super-powered individuals.

The Deviants, horrified by their own monstrous forms compared to the beautiful Eternals, developed a culture rooted in bitterness, paranoia, and conquest. They used their advanced intellect and proclivity for genetic engineering to build a vast, technologically superior empire that once spanned the globe. Their capital city, Lemuria, was established on the continent of Mu. This golden age came to a cataclysmic end when they declared war on their creators. The Second Host of the Celestials arrived in response to their hubris, unleashing their power and sinking the continent of Mu beneath the Pacific Ocean. The surviving Deviants established a new Lemuria deep beneath the waves and have spent the subsequent millennia as a subterranean race, nursing their ancient grudge. Their society became a brutal caste system, where one's physical form dictates their station. Led by a succession of warlords and priests, like the immortal Warlord Kro and the ambitious Priestlord Ghaur, they have continuously plotted against both the surface world and their hated Eternal cousins. Their religion often centers on worshipping the “Sleeping Celestial” (later revealed to be Tiamut The Communicator, the Dreaming Celestial), an entity they believe they can control to finally achieve victory.

The origin of the Deviants in the Marvel Cinematic Universe (designated Earth-199999) was significantly streamlined and altered for the film Eternals (2021). In this continuity, the Deviants are not a natural offshoot of humanity but are artificial, bio-engineered creatures. They were created millions of years ago by the Celestial Arishem the Judge. Their sole purpose was to be sent to planets seeded with new Celestial life (an “egg”) to hunt and eliminate the planet's apex predators. This would protect the burgeoning intelligent life forms, allowing their populations to grow. The growth of these intelligent populations would generate the necessary energy for the Celestial within the planet's core to “emerge,” a process that inevitably destroys the host planet. For a time, the Deviants performed their function perfectly. However, they began to evolve beyond their original programming. They became apex predators themselves and started preying upon the very intelligent life they were meant to protect. To correct this, Arishem created the Eternals, a group of synthetic, immortal beings with cosmic powers, to hunt down and exterminate the Deviants on every world. The Eternals believed they had successfully eliminated the last of the Deviants on Earth centuries ago. However, some had been frozen in the polar ice caps. As the Earth's temperature rose and the time of the “Emergence” of the Celestial Tiamut drew near, these surviving Deviants thawed and re-emerged. Imbued with cosmic energy from the impending birth, they began to evolve further. Their leader, later named Kro by Thena, discovered that by killing an Eternal and absorbing their cosmic energy, a Deviant could rapidly evolve, gaining humanoid characteristics, higher intelligence, and even a semblance of the slain Eternal's powers. This transformed them from simple beasts into sentient beings driven by a desire for survival and revenge against the Eternals and their creator, Arishem. This revision changes the Deviants from a tragic, fallen civilization into a tragic, living weapon that gained sentience and turned on its master. It simplifies the complex comic book lore of the three races, focusing the narrative on a direct creator-creation conflict.

The fundamental nature of the Deviants varies dramatically between the comics and the MCU, extending to their physical makeup, cultural structures, and technological capabilities.

• Biology:
  • Unstable Genome: The cornerstone of Deviant biology is their hyper-mutable genetic structure. No two Deviants (with extremely rare exceptions known as “pures” like Warlord Kro and Ransak the Reject) are born looking the same. Their offspring can bear absolutely no resemblance to the parents. This results in a staggering variety of physical forms, ranging from near-humanoid to utterly monstrous, often incorporating animalistic or demonic features.
  • Superhuman Attributes: Despite their varied forms, most Deviants possess physical attributes superior to a peak human, including enhanced strength, durability, speed, and reflexes. Their lifespan is also far greater than a human's, though not on par with the true immortality of the Eternals.
  • Powers and Abilities: Many Deviants are born with unique superhuman powers tied to their specific mutation, such as energy projection, shapeshifting (a rare and prized ability possessed by Kro), or immense physical strength.
  • The “Deviant Scent”: Eternals possess the ability to detect a unique pheromonal or genetic marker common to all Deviants, allowing them to instantly recognize one, regardless of its form.
• Society:
  • The Caste System: Deviant society is a rigid and cruel meritocracy based on physical form. Those with more powerful or aesthetically “pleasing” (by their standards) mutations form the ruling class, priesthood, and military elite.
  • Mutates: The vast majority of the population are “mutates,” individuals with hideous or non-functional deformities. They form the underclass, treated as slaves, laborers, or disposable shock troops in their armies. Mutates are often subjected to gladiatorial games or culled to maintain genetic “purity” within the ruling lines.
  • Religion and Governance: Their government is typically a monarchy or theocracy. Leaders like Priestlord Ghaur have often steered their culture towards the worship of powerful entities they hope to control, such as the Dreaming Celestial or the Serpent God Set. Their culture is defined by paranoia, ambition, internal scheming, and a profound, collective inferiority complex towards the physically perfect Eternals.
  • Lemuria: Their capital city, a sprawling, technologically advanced metropolis located deep beneath the Pacific Ocean. It is the heart of their civilization and military power.
• Technology:
  • Advanced Science: The Deviants are masters of science, particularly in the fields of genetics, engineering, and warfare. Their technology often rivals or even surpasses that of mainstream human civilization and is comparable to that of the Eternals.
  • Bio-engineering: They frequently practice selective breeding and genetic manipulation to create powerful warriors and living weapons, known as “mutates.”
  • Military Hardware: Their arsenal includes sophisticated energy weapons, powerful starships (often referred to as “raiders”), brain-mining devices, and advanced cloaking technology.

• Biology:
  • Bio-Engineered Predators: MCU Deviants are not a natural species but a manufactured one. Initially, they appeared as non-sentient, six-limbed, vaguely canine-like beasts with external, branch-like physiology. They shared a form of hive mind, coordinating their hunts.
  • Cosmic Energy Absorption: Their most critical biological trait is the ability to absorb cosmic energy, specifically from the Eternals they kill. This process triggers a radical evolution.
  • Accelerated Evolution: As seen with Kro, absorbing an Eternal's energy allows a Deviant to become more humanoid, develop full sentience and speech, and manifest a version of the fallen Eternal's powers (e.g., Kro gained Gilgamesh's ability to form cosmic energy constructs). Their physical bodies become more complex, healing from wounds and growing larger and more powerful with each Eternal absorbed.
• Society:
  • Pack to Tribe: Initially, their “society” was that of a simple predator pack. After evolving, Kro becomes the alpha and leader, forming a rudimentary tribe.
  • Vengeful Motivation: Their new, sentient culture is based on a shared memory of being hunted by the Eternals and a desire for vengeance against their creator, Arishem. Their goal is no longer predation but self-preservation and retribution. They do not have a city or a complex social structure, operating more as a vengeful, nomadic war party.
• Technology:
  • None: The Deviants of the MCU possess no technology whatsoever. Their power is entirely biological and innate. They fight with their claws, teeth, and absorbed cosmic abilities. This starkly contrasts with the hyper-advanced scientific civilization from the comics, positioning them as a purely natural/primal threat against the technologically-infused Eternals.

The Deviants' paranoid and treacherous nature means they rarely form true alliances, preferring to manipulate others or forge temporary pacts of convenience.

• Warlord Kro & Thena: The most significant and complex relationship is the centuries-long, on-again, off-again romance between the Deviant Warlord Kro and the Eternal warrior Thena. As one of the few immortal, shapeshifting Deviants, Kro has hidden his identity and interacted with Thena across different eras. Their love is a source of constant conflict, defying the very nature of their two warring peoples and serving as a rare bridge between them.
• Atlanteans: The Deviants have occasionally allied with factions from Atlantis, another subterranean civilization. The most notable partnership was between the Deviant priesthood and the Atlantean priestess Llyra in a plot involving the Serpent God Set.
• The Damocles Foundation: A human organization obsessed with acquiring Celestial technology and controlling superhuman evolution. They have captured and experimented on Deviants, but have also been known to work with them when their goals of manipulating cosmic power align.

• The Eternals: The Deviants' primary and eternal foes. This is the central conflict of their existence. It is a war of ideology, biology, and history. The Eternals see the Deviants as chaotic monsters to be contained, while the Deviants see the Eternals as arrogant, oppressive jailers and a symbol of the perfection they were denied. Their war has been fought in secret for millennia, shaping the myths and legends of humanity.
• The Celestials: Their creators, judges, and destroyers. The Deviants live in absolute terror of the Celestials, who have judged them unworthy and destroyed their empire in the past. Yet, in a display of immense hubris, factions like Priestlord Ghaur's have attempted to seize control of Celestial power, most notably by trying to awaken and command the Dreaming Celestial, Tiamut.
• Humanity: While sometimes ignored, humanity is often seen by the Deviants as a resource to be enslaved or a rival species to be eliminated. They resent humanity for being the Celestials' seemingly “favored” creation and the inheritors of the Earth's surface.

The primary affiliation of the Deviants is their own subterranean empire, based in the sunken city of Lemuria. Within Deviant society, there are numerous competing factions, most prominently:

• The Military: Led by a Warlord (most often Kro), focused on direct conquest and warfare against the surface and the Eternals.
• The Priesthood: Led by a Priestlord (most often Ghaur), focused on religious manipulation, scientific heresy, and seizing cosmic power through subterfuge.

These two factions are constantly vying for ultimate control of the Deviant throne.

In Jack Kirby's foundational series, the Deviants are introduced as the monstrous “demons” of Earth's past, preparing for war as the Fourth Host of the Celestials approaches Earth for its final judgment. The storyline establishes their history, the sinking of Lemuria, the brutal nature of their society (showcased through the gladiator Ransak the Reject), and the forbidden romance between Kro and Thena. Their leader, Tode, captures the Eternals in an attempt to present them to the Celestials as a “pest” to be cleansed, a plan that backfires spectacularly and cements the core dynamic between the two races.

During this massive annual crossover event, the High Evolutionary sought to forcibly guide the evolution of all life, deeming the Deviants' unstable genetics a cosmic abomination that must be sterilized. In response, Priestlord Ghaur united the Deviant race in a grand scheme. He captured the Eternals and used their life force to form a “Uni-Mind,” then siphoned its power in an attempt to merge with the Dreaming Celestial and gain ultimate godhood. This act positioned the Deviants not just as a threat to Earth, but as a force capable of seizing cosmic power on a universal scale.

In this celebrated miniseries by Neil Gaiman and John Romita Jr., the Eternals and Deviants have their memories and powers suppressed by the Eternal Sprite. They live on Earth as ordinary humans, unaware of their true heritage. The story follows Ikaris and Makkari as they slowly reawaken their peers. The Deviants are presented in a more tragic light, with their leaders—now a warlord in charge of a Serbian arms-dealing party and a socialite—struggling with faint, monstrous memories. The plot culminates in the reawakening of the Dreaming Celestial in San Francisco, an event the Deviants both worship and fear, revealing the profound and terrifying bond between them and their “sleeping god.”

• Marvel Cinematic Universe (Earth-199999): This is the most radically different and widely known variant. As detailed extensively above, they are not a civilization but a species of bio-engineered predators that evolved sentience. This version strips away their technology, complex society, and internal politics, reframing them as a force of nature twisted by their own creators, with their leader Kro serving as a dark reflection of the Eternals' own struggle with their purpose.
• Marvel Knights: Eternals (Motion Comic): This direct adaptation of the Gaiman/Romita Jr. storyline presents a faithful version of the Earth-616 Deviants. It captures their re-imagining as amnesiacs living among humans and the eerie horror of their slow reawakening. It's one of the most accurate depictions of the modern comic book Deviants outside of the source material.
• Heroes Reborn (1996): In the pocket universe created by Franklin Richards, a version of the Deviants and their leader Warlord Kro existed. This version, from the sunken city of Lemuria, attacked New York and came into direct conflict with the newly re-formed Avengers of that reality, showcasing their classic role as subterranean conquerors.
