Skrulls

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

Part 2: Origin and Evolution

Publication History and Creation

The Skrulls made their debut in the nascent days of the Marvel Age of Comics, first appearing in Fantastic Four #2 in January 1962. Created by the legendary duo of writer Stan Lee and artist Jack Kirby, the Skrulls were a perfect embodiment of Cold War-era anxieties. They were conceived during a period of intense public paranoia about “the enemy within,” drawing thematic parallels to films like Invasion of the Body Snatchers and the political fears surrounding covert spies and sleeper agents. Their initial appearance portrayed them as classic sci-fi “little green men,” albeit with the terrifying ability to change their shape. Kirby's design, with their large, pointed ears, wrinkled chins, and green skin, became instantly iconic. Lee's narrative established them not just as monsters, but as a cunning, technologically superior race with a clear agenda of conquest. This first encounter with the fantastic_four, where they were cleverly defeated by being tricked into impersonating cows, set a precedent for their combination of immense power and occasional hubris. Over the decades, they evolved from simple alien invaders into a complex civilization with a deep history, a unique culture, and a tragic, war-torn legacy.

In-Universe Origin Story

A critical distinction must be made between the Skrulls' origins in the comics and their re-imagined history in the MCU. The two narratives are fundamentally different and inform their respective motivations and roles in their universes.

Earth-616 (Prime Comic Universe)

The Skrulls' origins are ancient, dating back millions of years to a time when the cosmic beings known as the celestials visited their home planet, Skrullos. The Celestials experimented on the native reptilian race, splitting their evolutionary path into three distinct branches:

A brutal civil war erupted between the three branches. The Deviants, with their inherent advantage of disguise and adaptation, ultimately proved victorious, completely eradicating the Prime and Eternal branches. From that point forward, all Skrulls descended from this shapeshifting Deviant stock. The sole surviving Eternal, Kly'bn, was elevated to godhood in their pantheon, and the Skrulls came to believe that shapeshifting was the ideal and “true” form of their species. Their expansion into a galactic empire began when they encountered two primitive species on the planet Hala: the plant-like Cotati and the humanoid Kree. The Skrulls, then a relatively peaceful and commercial empire, proposed a contest to determine which race would receive their advanced technology. After a year, the Cotati's creation was deemed superior. Enraged and humiliated, the Kree slaughtered the Cotati and the Skrull delegates, seized the Skrulls' technology for themselves, and initiated the Kree-Skrull War—a conflict that would last for millennia and redefine both civilizations, transforming the Skrulls from a commercial power into a hardened, militaristic empire.

Marvel Cinematic Universe (MCU)

The MCU presents a starkly different and more sympathetic origin story for the Skrulls. First detailed in the film Captain Marvel (2019), the MCU's Skrulls are not galactic conquerors but a race of refugees on the brink of extinction. In this continuity, the Skrulls were a peaceful race whose homeworld, Skrullos, was annihilated by the aggressive, xenophobic kree Empire. The Kree launched a genocidal war against them, hunting the last survivors across the galaxy. The Skrulls' shapeshifting ability became not a tool for conquest, but a desperate means of survival, allowing them to hide in plain sight from their relentless pursuers. A faction of Skrulls, led by their general Talos, came to Earth in the 1980s seeking refuge and the help of a rogue Kree scientist, Mar-Vell (posing as Dr. Wendy Lawson). Mar-Vell was developing a light-speed engine powered by the Tesseract, which she intended to use to transport the Skrull survivors to a new, safe home far beyond the Kree's reach. After Mar-Vell's death, Carol Danvers discovers the truth and, empowered as Captain Marvel, vows to help the Skrulls find a new homeworld. This fundamental re-contextualization shifts the Skrulls from villains to victims. Their story in the MCU is one of loss, diaspora, and the search for a home, a narrative further explored in Spider-Man: Far From Home and the Secret Invasion series. The latter series reveals the consequences of this long, unfulfilled promise, showing a radicalized faction of Skrulls led by Gravik who believe that infiltration and conquest of Earth is their only remaining path to survival.

Part 3: Biology, Culture & Technology

The nature of the Skrulls as a species and a society differs profoundly between the comic and cinematic universes, reflecting their different core narratives.

Part 5: Iconic Events & Storylines

The Kree-Skrull War (Avengers #89-97, 1971)

This landmark storyline by Roy Thomas, Neal Adams, and John Buscema was one of Marvel's first universe-spanning epics. The ancient conflict between the two alien empires spilled over to Earth, with the Avengers caught in the middle. The story featured Captain Marvel (Mar-Vell), the Inhumans, and the Supreme Intelligence, revealing deep cosmic lore. The Skrulls were portrayed as cunning manipulators, attempting to devolve humanity back to its primitive state. The event established the massive scale of the Marvel cosmos and cemented the Kree and Skrulls as major players.

Annihilation (2006)

While not a Skrull-centric event, their role was pivotal. The Annihilation Wave, a devastating armada from the Negative Zone, tore through the positive-matter universe. The Skrull Empire was one of its first major victims. Their entire Throneworld was consumed, and their fleet was shattered. This catastrophic loss created a power vacuum and a sense of apocalyptic desperation within Skrull society, directly setting the stage for their most desperate gamble. It explained why they would risk everything on a single, all-or-nothing invasion of Earth.

Secret Invasion (2008)

Arguably the definitive Skrull storyline. Written by Brian Michael Bendis, this event was the culmination of years of meticulous planning, both by the Skrulls in-universe and by Marvel's writers. It was revealed that a radical religious sect of Skrulls, led by Queen Veranke (impersonating Spider-Woman), had been systematically replacing heroes, villains, and political leaders across the globe for years. Their new infiltration techniques made them completely undetectable. The invasion erupted into a global war, turning hero against hero as no one knew who to trust. The event's climax saw Norman Osborn land the killing blow on the Skrull Queen, an act which propelled him to a position of national power and ushered in the Dark Reign era.

Empyre (2020)

This event represented the single greatest paradigm shift in Skrull history. The young hero Hulkling, son of the Kree hero Mar-Vell and the Skrull Princess Anelle, accepted his destiny and united the Kree and Skrull empires under a single banner. Wielding the legendary Star-Sword, he became Emperor Dorrek VIII of the new Kree-Skrull Alliance. Their first act was to launch a massive armada towards Earth, not to conquer it, but to destroy the plant-like Cotati, who had revealed themselves to be a genocidal threat to all animal life. The event saw the Avengers and Fantastic Four siding with their former enemies to save the galaxy, forever changing the cosmic political map.

Notes and Trivia

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

1)
The Skrulls' creation in 1962 was heavily influenced by the Red Scare and McCarthyism in the United States, tapping into a cultural fear of hidden enemies and communist infiltration.
2)
In the MCU, the name “Chitauri” is used for the alien army that Loki leads in The Avengers (2012). These are servants of Thanos and are a distinct species from the Skrulls. This was a divergence from the Ultimate Comics, where the Chitauri were that universe's version of the Skrulls.
3)
Legal rights surrounding the Skrulls were once complex. While Marvel Studios had the rights to the Skrull race, 20th Century Fox held the film rights to the Fantastic Four, which included specific Skrull characters like Kl'rt the Super-Skrull. This is why Skrulls could appear in Captain Marvel but the Super-Skrull, in his classic form, could not until after Disney's acquisition of Fox.
4)
The Skrull language is known as Skrullian, and their writing system is called Skrullos.
5)
A well-known Skrull delicacy is the Z'Rell, a type of worm.

Key comic book issues for further reading include: Fantastic Four #2 (First Appearance), Avengers #89-97 (Kree-Skrull War), New Avengers #1-47 (Build-up to Secret Invasion), Secret Invasion #1-8 (Main Event), and Empyre #1-6 (Formation of the Kree-Skrull Alliance).
