Skrulls

• Core Identity: The Skrulls are a technologically advanced, militaristic civilization of reptilian humanoid shapeshifters, whose mastery of espionage and infiltration makes them one of the most persistent and unpredictable threats in the Marvel Universe.
• Key Takeaways:
• Role in the Universe: Originally the dominant power in the Andromeda Galaxy, the Skrull Empire is defined by its millennia-long, existential war with the kree Empire. Their core ability to perfectly imitate other beings makes them galactic masters of subterfuge, capable of destabilizing entire worlds from within. secret_invasion.
• Primary Impact: The Skrulls' most significant impact is the pervasive paranoia they sow. Their ability to replace anyone, from a civilian to a superhero, was the basis for the Earth-shattering Secret Invasion, an event that broke the trust of the hero community for years. Their actions have directly catalyzed major galactic and terrestrial conflicts.
• Key Incarnations: In the primary comic continuity (Earth-616), the Skrulls are a proud, ancient, and often ruthless imperialistic power. In the Marvel Cinematic Universe (MCU), they are reimagined as a sympathetic race of refugees, their homeworld destroyed by the Kree, desperately seeking a new home and protection from their oppressors.

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.

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.

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:

• The Prime Skrulls: The baseline, non-powered evolutionary path, similar to humanity.
• The Skrull Eternals: A long-lived, powerful variant imbued with cosmic energy, led by Kly'bn.
• The Skrull Deviants: A variant with a mutable genetic code, granting them the power of shapeshifting.

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.

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.

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

Biology and Abilities:

• Metamorphic Physiology: The Skrulls' defining trait is their complete conscious control over the molecules of their bodies. This allows them to alter their shape, size, color, and texture at will. They can flawlessly replicate the appearance of any humanoid or object, including clothing and equipment.
• Mimicry: Their imitation is not just skin-deep. They can replicate specific genetic markers and even the powers of some superhumans, though typically at a much lower level unless augmented.
• Psychic Detection Vulnerability: Highly powerful telepaths, like professor_x or jean_grey, can often detect a Skrull's true mind beneath their disguise.
• Technological Detection: Certain advanced technologies, such as Reed Richards' specialized scanners or S.H.I.E.L.D. protocols, can identify their unique biological signature. However, during the Secret Invasion storyline, the Skrulls developed a new infiltration method that made them undetectable by both psychic and technological means.
• Super-Skrulls: The most formidable Skrull warriors are those who undergo the Super-Skrull process. The original, Kl'rt, was bio-engineered to possess the combined powers of the fantastic_four. Later versions were created with the powers of other heroes, making them incredibly powerful and versatile soldiers.

Culture and Society:

• Imperial Theocracy: The Skrull Empire is an absolute monarchy, ruled by an Emperor or Empress from the Throneworld (originally Skrullos, later Tarnax IV, and others after various destructions).
• Militarism: Skrull society is deeply militaristic and expansionist, a direct result of their eternal war with the Kree. Military service is a high honor, and conquest is seen as a birthright.
• Religious Dogma: Their religion revolves around the prophecy of Kly'bn and Sl'gur't, the Skrull gods, which states, “He loves you.” This phrase was twisted by Queen Veranke during the Secret Invasion to justify the conquest of Earth, claiming it was a promised holy land.
• Intrigue and Deception: Deceit is not just a tactic but a deeply ingrained part of their culture. Political maneuvering, assassinations, and betrayal are common within the imperial court.

Technology: The Skrulls possess technology far in advance of Earth's.

• Starships: They command massive fleets of interstellar warships capable of devastating entire planets.
• Weaponry: They utilize advanced energy-based weapons, from personal sidearms to planet-destroying cannons.
• Genetic Engineering: Their mastery of genetics is central to their power, allowing them to create Super-Skrulls, clone powerful individuals, and augment their soldiers.

Biology and Abilities:

• Shapeshifting: The core ability remains the same. A Skrull can perfectly replicate the appearance and voice of another being. The process requires intense concentration.
• Memory Probing: When a Skrull copies a person, they can access their recent memories, allowing for a more convincing impersonation. This is demonstrated by Talos when he probes a Kree soldier's mind in Captain Marvel.
• No Known Weaknesses: The MCU has not yet established a specific weakness to their shapeshifting, such as a telltale sign or a common detection method, making them exceptionally effective infiltrators.
• Super-Skrulls (Gravik's Faction): In the Secret Invasion series, a radical Skrull named Gravik creates a machine to imbue Skrulls with superpowers. Using a collection of DNA from Earth's most powerful beings (called “The Harvest”), he creates a new generation of Super-Skrulls. These Skrulls can manifest powers such as Groot's elasticity, Extremis's healing and heat generation, and Cull Obsidian's super-strength. Gravik himself becomes the most powerful, capable of using multiple powers at once.

Culture and Society:

• Refugee Diaspora: With Skrullos destroyed, their society is fractured and scattered. There is no empire or central government.
• Survivalist Factions: The Skrulls are divided into at least two main ideological camps.
  • Talos's Faction: Those who maintain hope and work with nick_fury and captain_marvel_carol_danvers, believing in a peaceful solution and coexistence.
  • Gravik's Insurgency: A younger, more radicalized generation who feel betrayed by Fury's unfulfilled promise of finding them a home. They believe that humanity is weak and that Earth should be taken by force to become the new Skrullos.
• Loss of Identity: Their culture is one of mourning. They have lost their home, their government, and a cohesive sense of identity, which fuels the desperation of the insurgency.

Technology:

• Salvaged and Adapted: While capable of interstellar travel, the MCU Skrulls' technology appears less advanced than their comic counterparts. They often use salvaged ships and adapted alien technology. Their most significant piece of native tech shown is Gravik's Super-Skrull machine, a desperate gambit born from their circumstances.

The Skrulls, particularly in Earth-616, are known more for their enmities than their alliances. However, key relationships have formed.

• The Kree-Skrull Alliance (Earth-616): The most significant and shocking alliance in their history. Under the leadership of the Kree-Skrull hybrid Emperor Hulkling (Dorrek VIII), the two ancient enemies united their empires into a single, formidable galactic power. This alliance fundamentally reshaped the cosmic landscape of the Marvel Universe.
• Nick Fury (MCU): Fury has been the Skrulls' most important human ally for decades. He promised to find them a new home and, in return, has utilized a network of Skrull operatives (including Talos and his wife Soren) for intelligence and espionage missions, as seen in Spider-Man: Far From Home and Secret Invasion. This relationship is complex, built on mutual need but strained by unfulfilled promises.
• Captain Marvel (Carol Danvers) (MCU): As the one who discovered their plight and vowed to protect them, Carol Danvers is the Skrulls' champion. Her quest to find them a safe haven is a primary motivation for her cosmic journeys between her film appearances.

• The Kree Empire: This is the defining conflict of the Skrull race. Their war has raged for millions of years, costing trillions of lives and shaping both societies into militaristic, xenophobic powers. The hatred between them is genetic, cultural, and absolute, making their eventual alliance under Hulkling all the more monumental.
• The Fantastic Four: As the first heroes on Earth to repel a Skrull invasion, the Fantastic Four have been a perpetual thorn in the Empire's side. Reed Richards' intellect has outsmarted them countless times, and the team's power has thwarted many of their schemes, including those of their greatest champion, the Super-Skrull.
• The Avengers: As Earth's primary defenders, the Avengers have clashed with the Skrulls during numerous invasion attempts, most notably the Kree-Skrull War and the Secret Invasion. The latter event made the conflict deeply personal, as the Skrulls replaced heroes within their own ranks, shattering the team's trust.

• The Skrull Empire (Earth-616): The central governing body for the vast majority of Skrulls in the comics. A sprawling, interstellar dominion with countless member worlds.
• S.A.B.E.R. (MCU): The space-based intelligence organization run by Nick Fury is heavily staffed by his Skrull allies. They operate from a massive space station, serving as Earth's first line of defense against cosmic threats, a role detailed in WandaVision and The Marvels.
• The Annihilation Wave (Earth-616): During the Annihilation event, the Skrull Empire was one of the major powers that stood against the invading forces of Annihilus from the Negative Zone. They suffered devastating losses, including the destruction of their Throneworld, which directly weakened them ahead of their subsequent Secret Invasion attempt.

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.

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.

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.

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.

• Ultimate Universe (Earth-1610): The Skrulls of this reality are called the Chitauri. They are a far more monstrous and less subtle race. Rather than being individualistic infiltrators, they are a hive-minded, colonial species that can shapeshift but primarily seeks to consume and absorb entire civilizations. They were led by Herr Kleiser, a super-soldier equivalent who fought Captain America in World War II. This interpretation of a more overtly monstrous alien race heavily influenced the design and role of the alien army in the 2012 MCU film, The Avengers, who were also named Chitauri.
• Marvel Zombies (Earth-2149): When the Fantastic Four of this reality became zombies, their first off-world victims were the Skrulls who had come to Earth to offer them a cure in exchange for their surrender. The zombified FF devoured the Skrulls, and the zombified Super-Skrull returned to the Skrull Throneworld, spreading the hunger plague and dooming his entire civilization.
• Fantastic Four: World's Greatest Heroes (Animated Series, 2006): This series featured a notable episode, “My Neighbor Was a Skrull,” which played on the classic “body snatchers” theme. The Baxter Building's new landlord, a seemingly kindly old woman, is revealed to be a Skrull scout, leading to a direct confrontation with the Super-Skrull. It was a modern and lighthearted take on the classic infiltration premise.
