Deviants

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

The Deviants burst onto the comic book scene in The Eternals #1, published in July 1976. They were conceived by the legendary writer and artist Jack “The King” Kirby upon his celebrated return to Marvel Comics in the mid-1970s. This period marked a creative renaissance for Kirby, who sought to build a new, grand mythology within the Marvel Universe, separate from the heroes he had co-created in the 1960s. Kirby's work on The Eternals was heavily influenced by Erich von Däniken's popular “ancient astronaut” theories, which posited that extraterrestrials had visited early Earth and were responsible for humanity's technological and mythological development. The Deviants, Eternals, and their creators, the Celestials, were Kirby's comic book manifestation of this concept. The Deviants served as the perfect antagonists in this new cosmic pantheon: the flawed, monstrous “devils” to the Eternals' angelic “gods.” Their grotesque and infinitely varied designs allowed Kirby's famously dynamic and imaginative art style to flourish, filling pages with a menagerie of incredible creatures. Thematically, they explored ideas of genetic determinism, societal outcasts, and the nature of monstrosity, adding a layer of tragic depth to their role as villains.

In-Universe Origin Story

The origin of the Deviants is a tale of cosmic experimentation gone awry, with starkly different narratives between the primary comic universe and its cinematic adaptation.

Earth-616 (Prime Comic Universe)

Approximately one million years ago, the colossal space gods known as the First Host of the Celestials arrived on Earth. They found nascent life in the form of early hominids and, as they had done on countless worlds, began a series of genetic experiments. From this common stock, they engineered three distinct species:

The Deviants, with their superior strength and intellect over early humans, quickly developed an advanced civilization. Using their mastery of genetic engineering and technology, they established a vast, global empire centered on the continent of Lemuria. They enslaved the burgeoning human race and, in their hubris, decided to challenge their creators when the Second Host of the Celestials arrived for a planetary assessment. This act of defiance was met with swift and terrible judgment. The Celestials unleashed a cataclysm that sank Lemuria and much of the Deviant empire beneath the ocean, an event that would later be mythologized by humans as the “Great Flood.” The surviving Deviants were driven underground into subterranean cities, the largest of which was the rebuilt capital, also named Lemuria. This foundational trauma instilled in their culture a deep-seated fear and resentment of the Celestials and a burning hatred for their favored cousins, the Eternals, sparking a war that has lasted for millennia.

Marvel Cinematic Universe (MCU)

The MCU, as detailed in the 2021 film Eternals, presents a radically different and streamlined origin for the Deviants. They were not a result of experiments on early humans but were instead artificially created beings engineered by the Celestial Arishem the Judge. Their original purpose was entirely functional: they were created to be a form of cosmic pest control. On planets seeded with a nascent Celestial, like Earth, the Deviants were dispatched to eliminate the planet's apex predators. This would allow intelligent species, such as humanity, to thrive and multiply unhindered. A large, intelligent population is a prerequisite for the “Emergence,” the birth of the new Celestial, which consumes the planet in the process. However, the Deviants evolved beyond Arishem's control. They began to prey on the very intelligent life they were meant to protect, becoming a plague upon the worlds they were sent to cleanse. To correct this error, Arishem created a new set of synthetic beings: the Eternals. The Eternals were programmed to be immortal androids with cosmic powers, and their sole mission was to hunt the Deviants to extinction on each seeded planet, thereby ensuring the Emergence could proceed as planned. On Earth, the Eternals believed they had succeeded in killing the last Deviant centuries ago. However, some had survived, frozen in the ice. As the energy signatures heralding the coming Emergence of the Celestial Tiamut grew, the ice melted and the Deviants re-emerged. They had evolved a terrifying new ability: the power to absorb the cosmic energy of the Eternals they killed. This absorption not only healed and empowered them but also allowed their leader, a Deviant later named Kro by Thena, to develop sentience, humanoid features, and the ability to speak, transforming him from a mere beast into a vengeful intelligence seeking to halt the Emergence that would destroy his new home.

Part 3: In-Depth Analysis: Biology, Culture & Technology

The fundamental nature of the Deviants differs so profoundly between the comic and film universes that they are almost entirely different concepts.

Earth-616 (Prime Comic Universe)

Biology and Genetics

The defining feature of the Deviant race is their unstable genetic code. This results in what is known as “maverick genetics,” where every individual's offspring will have a completely unpredictable set of mutations.

Culture and Society

Deviant society is a rigid, paranoid, and often brutal hierarchy built upon principles of genetic “purity” (a paradoxical concept for their race) and absolute authority.

Technology

Despite their monstrous appearance, the Deviants are technological geniuses, particularly in the fields of genetics and warfare.

Marvel Cinematic Universe (MCU)

Biology and Evolution

In the MCU, the Deviants are purely biological weapons, and their physiology reflects this singular purpose.

Culture and Society

Initially, the MCU Deviants have no culture. They are a pack of predators operating on instinct. Their primary drive is survival and killing Eternals. However, the evolution of Kro marks a turning point. He develops a personal motivation: revenge against his creators, the Eternals and Arishem, and a desire to stop the Emergence to save Earth as his home. This is the first flicker of a potential future culture, one founded on a shared traumatic past and a singular, unifying goal.

"Technology"

The Deviants in the MCU possess no technology. All of their weapons and abilities are purely biological, extensions of their own monstrous forms.

Part 4: Key Figures & Relationships

While the MCU's Deviants are largely faceless monsters, the comic universe features a rich cast of complex Deviant characters.

Arch-Enemies

Affiliations

The Deviants are fiercely xenophobic and isolationist, rarely forming alliances with outside powers. Their primary “affiliations” are typically networks of puppets or slaves. They have used their advanced technology to create the Delta Network, a clandestine web of human agents placed in positions of power across the globe to destabilize surface governments. On rare occasions, facing a mutual threat like a hostile Celestial judgment or the invasion of an Elder God, Warlord Kro has brokered temporary, uneasy truces with the Eternals or even Earth's heroes like the avengers.

Part 5: Iconic Events & Storylines

The Eternals Saga (//The Eternals// Vol. 1, 1976-1978)

Jack Kirby's original epic introduced the world to the Deviants. The story centers on the arrival of the Fourth Host of Celestials on Earth to pass judgment on their creations. This forces the Eternals, Deviants, and humanity into the open. The Deviants, led by Brother Tode and Warlord Kro, attempt to turn humanity against the “space gods” by presenting them as a threat. This storyline establishes their core conflict with the Eternals, Kro's complex relationship with Thena, and their absolute terror of their creators.

Atlantis Attacks (1989 Crossover)

This massive crossover event saw the Priestlord Ghaur unite the Deviants with the Atlanteans under attuma. Ghaur's master plan was to bring the Serpent God set to Earth, using the formidable psychic Llyra as his high priestess. To achieve this, he required the creation of a new Serpent Crown. The plot involved kidnapping seven superhuman women (the “Brides of Set”) and battling nearly every major hero in the Marvel Universe, from the Avengers to the Fantastic Four, showcasing the scope of the Deviants' threat when led by a truly ambitious mind.

The Dreaming Celestial (//Eternals// Vol. 3, 2006-2007)

In this celebrated modern revival by Neil Gaiman and John Romita Jr., the Eternals have been mind-wiped and are living as ordinary humans, with no memory of their true nature. The Deviants, taking advantage of this, plan to awaken the long-dormant Dreaming Celestial, Tiamut, who is imprisoned beneath San Francisco. They believe that by freeing their “anti-god,” they can destroy the other Celestials and remake the world in their image. The story re-establishes the deep lore of the races for a new generation and highlights the apocalyptic scale of Deviant ambition.

Notes and Trivia

1) 2) 3) 4) 5) 6)

1)
The name “Deviant” is an exonym given to them by the Eternals. Their own name for their species is rarely, if ever, stated.
2)
The concept of a genetically superior offshoot of humanity (Eternals) warring with a genetically “inferior” or monstrous branch (Deviants) is a recurring theme in Jack Kirby's work, mirroring the New Gods and the monstrous Parademons of Apokolips he created for DC Comics.
3)
It is a common misconception that Thanos is a Deviant. Thanos is an Eternal from the colony on Titan who was born with the “Deviant Syndrome,” a rare genetic condition that gave him the physical appearance (purple skin, massive jaw) of a Deviant while still retaining his Eternal physiology and potential. This is different from being a member of the Deviant race from Earth.
4)
Over the millennia, some Deviants integrated with the lost civilization of Lemuria's human population before it sank, and their descendants are believed to be the basis for the aquatic Homo mermanus, the race to which Namor the Sub-Mariner and the Atlanteans belong.
5)
The Deviants' religion, particularly their worship of the Dreaming Celestial, carries strong Lovecraftian undertones of worshipping immense, sleeping cosmic entities whose awakening means doom for all.
