The Kree-Skrull War

• Core Identity: The Kree-Skrull War is the foundational, galaxy-spanning conflict between two of the Marvel Universe's oldest and most powerful alien empires, a perpetual state of attrition that has repeatedly dragged Earth and its heroes into the crossfire.
• Key Takeaways:
• Role in the Universe: This ancient, seemingly endless war serves as the primary engine of cosmic conflict in the Marvel Universe. It defines the political landscape of the Andromeda and Large Magellanic Cloud galaxies and is the origin point for countless characters and events, including captain_mar-vell's connection to Earth and the subsequent rise of Carol Danvers.
• Primary Impact: Its most famous chapter, chronicled in the pages of Avengers, was a paradigm shift for Earth's heroes. It elevated them from planetary defenders to galactic players, directly led to the formation of the secretive illuminati, and planted the seeds of paranoia that would later blossom into the devastating secret_invasion.
• Key Incarnations: The core difference between the comics and the MCU lies in its framing. In the Earth-616 comics, the war is a morally gray struggle between two equally ruthless, expansionist empires. The Marvel Cinematic Universe (MCU) re-imagines the conflict as a Kree-led genocide against the Skrulls, who are initially presented as sympathetic refugees seeking a new home.

The Kree-Skrull War storyline was a landmark event in comic book history, first published across nine issues of Marvel Comics' Avengers title, from issue #89 to #97 (June 1971 - March 1972). The epic was primarily conceived and written by a young Roy Thomas, who sought to create a sprawling, novelistic narrative that would rival the scale of literary science fiction. The ambition was to craft a “war comic” that was more than just heroes punching villains; it was to be a complex saga with political intrigue, moral ambiguity, and universe-altering consequences. The artistic duties were split between two of the era's titans. Sal Buscema provided the pencils for the initial and concluding chapters, bringing his signature dynamic and character-focused style. The middle section of the arc was penciled by the legendary Neal Adams, whose photorealistic and innovative layouts brought a new level of cinematic grandeur and emotional depth to the cosmic conflict. The combined artistic vision gave the story a unique feel, blending classic superhero action with a more grounded, serious tone. Published at the dawn of the Bronze Age of Comic Books, the Kree-Skrull War reflected the growing complexities of the time. It contained a strong allegorical subplot involving McCarthyism and government paranoia, directly challenging the simpler moral certainties of the preceding Silver Age. It was one of the first true “event” storylines in Marvel's history, weaving together disparate threads from Fantastic Four, Captain Marvel, and The Incredible Hulk to create a cohesive, universe-defining narrative that is still referenced as a high-water mark for the medium.

The conflict chronicled in the Avengers comic was merely one chapter in a war that had raged for millions of years. The true origins of this cosmic animosity are ancient and deeply rooted in jealousy and betrayal, a story that differs significantly between the prime comic universe and the cinematic adaptation.

The genesis of the Kree-Skrull War dates back to a time when both races were still primitive. A star-faring, god-like race known as the celestials conducted genetic experiments on the ancestors of humanity, but it was a different ancient race, the pacifistic Skrulls of Skrullos, who first achieved space travel. In their early exploratory phase, the Skrulls were benevolent, sharing their technology and knowledge with “lesser” races. They arrived on the planet Hala, home to two sentient species: the barbaric, humanoid Kree and the peaceful, plant-like Cotati. To determine which race was worthy of their technological gifts, the Skrulls proposed a test. They took groups from both species to Earth's uninhabited moon, providing them with resources and one year to create something of value. The Kree, using their brute strength and engineering prowess, constructed a magnificent, technologically advanced city. The Cotati, in contrast, used their horticultural abilities to cultivate a beautiful, complex garden. When the Skrulls returned, they judged the Cotati's creation to be the nobler achievement. Enraged by this perceived slight, the Kree contingent slaughtered the Cotati and the Skrull delegates. They then reverse-engineered the Skrulls' starship, rapidly advancing their own technology. Decades later, the newly space-faring Kree launched a pre-emptive strike on the Skrull Throneworld, initiating a war that would engulf galaxies and span millennia. The Skrulls, forced to abandon their pacifist ways, became a militaristic, deceptive empire of shapeshifters. The Kree, driven by their inferiority complex and xenophobia, became a rigid, martial society controlled by the supreme_intelligence. This single act of jealousy on Earth's moon sparked the longest and most destructive war the universe had ever known.

The MCU drastically simplifies and re-contextualizes the war's origins, presenting it through the lens of Carol Danvers's journey in Captain Marvel (2019). In this continuity, the conflict is not a symmetrical struggle between two empires but a one-sided war of annihilation waged by the Kree against the Skrulls. The MCU's Skrulls, led by talos, were a species who refused to submit to Kree dominion. In retaliation, the Kree Empire destroyed their home planet, Skrullos, rendering the survivors a scattered, homeless refugee population. The war, as depicted in the film, is actually the Kree's systematic hunt for these remaining Skrulls across the galaxy under the guise of fighting “terrorists.” A Kree scientist named Mar-Vell, disillusioned with her empire's genocidal campaign, defected and fled to Earth. Under the alias Dr. Wendy Lawson, she worked to develop a light-speed engine using the Tesseract's energy, intending to transport the remaining Skrull refugees to a new home beyond the Kree's reach. Her death and the subsequent accident involving pilot Carol Danvers led to the creation of Captain Marvel. The entire conflict is framed by the propaganda of the supreme_intelligence, which portrays the Kree as noble warriors and the Skrulls as insidious infiltrators. The core revelation of the film is that the Skrulls are not villains but desperate victims. This fundamentally alters the dynamic, shifting the moral culpability almost entirely onto the Kree and setting up the Skrulls as allies of Nick Fury and Captain Marvel, a stark departure from their traditional role as antagonists in the comics. The war effectively ends for this faction of Skrulls when Carol defeats the Kree fleet, but the consequences of their displacement continue to unfold in later projects like the Secret Invasion series.

While the war itself is ancient, the “Kree-Skrull War” as an event primarily refers to the specific storyline in Avengers #89-97. This section breaks down that pivotal chapter and its MCU counterpart.

The conflict for Earth's heroes began subtly, escalating from a series of seemingly disconnected events into a full-blown galactic crisis.

The war comes to Earth through captain_mar-vell, a Kree warrior sent as a spy who develops an affinity for humanity. His activities attract the attention of his superior, ronan_the_accuser, who attempts to devolve humanity using Kree technology, but is thwarted by Mar-Vell and the Avengers. Simultaneously, the Vision suffers a catastrophic breakdown, allowing the Avengers to discover his android brain patterns are a copy of the deceased hero Wonder Man. While being repaired by his creator, Ultron, his journey leads him to the Inhumans in Attilan. This subplot reveals the Inhumans' origins as a Kree experiment, tying another major Marvel race directly to the conflict. The public-facing element of the war begins when a Skrull senator, disguised as a human, launches a campaign to turn the public against the Avengers. This mirrors the McCarthy-era “Red Scare,” with the “Committee to Gain Control of Super-Humans” demanding the team disband. This internal pressure divides the Avengers just as the external threat is mounting.

The true scope of the war is revealed when three Avengers—Quicksilver, Scarlet Witch, and the Vision—are abducted by Skrulls. The remaining Avengers, aided by Captain Mar-Vell, pursue them into space. They learn that the Skrulls have been masquerading as Captain America, Thor, and Iron Man to sow discord. This leads to a direct confrontation with the Super-Skrull, a powerful warrior imbued with the combined abilities of the Fantastic Four. The Avengers find themselves fighting battles on the Skrull Throneworld and on Hala, the Kree homeworld. They are hopelessly outmatched, small players in an immense galactic chess game. They discover that both empires have constructed massive armadas, with Earth positioned directly in the crossfire. The Skrulls intend to destroy Earth to prevent the Kree from using it as a strategic base, while the Kree see Earth's population as a potential asset or an acceptable casualty.

The climax of the war hinges on rick_jones, the perennial Marvel sidekick. After being exposed to the “Psyche-Magnitron” by Ronan, Rick discovers he possesses a latent cosmic power known as the Destiny Force—a manifestation of humanity's ultimate evolutionary potential. As the Skrull armada arrives in Earth's solar system, poised for annihilation, the Kree supreme_intelligence reveals its true plan. It telepathically contacts Rick Jones and explains that it orchestrated many of the preceding events not to win the war, but to unlock the Destiny Force within him. The Supreme Intelligence had long recognized the Kree were at an evolutionary dead end, and it sought to use Rick's power to jump-start their genetic potential. In a climactic moment, Rick Jones unleashes the Destiny Force. The immense psychic energy doesn't destroy the fleets, but instead projects images of their childhood fears and freezes every Kree and Skrull warrior in the armada in a state of suspended animation, instantly halting the battle. The immediate threat is neutralized, but the war itself is far from over.

The Kree-Skrull War had profound, long-lasting consequences.

• The Illuminati: Tony Stark realized that Earth's heroes were completely unprepared for such a threat and that they couldn't trust outside governments or organizations. He secretly assembled the Illuminati—a council of the most powerful and influential minds on Earth (mr_fantastic, professor_x, doctor_strange, black_bolt, and namor)—to deal with future threats of this magnitude preemptively. This group's actions would have massive repercussions for decades.
• A New Era for the Avengers: The team was no longer just a New York-based club of heroes. They had proven themselves on a galactic stage, earning both the respect and the unwanted attention of cosmic powers.
• Seeds of Paranoia: The ease with which the Skrulls infiltrated Earth's power structures left a lasting scar, creating an atmosphere of distrust that would be exploited to its fullest extent years later during the Secret Invasion event.

The MCU's version of the war is less a sprawling epic and more a personal origin story, primarily confined to the events of Captain Marvel.

The “war” as seen by the audience is the Kree Starforce, including Carol Danvers (then known as “Vers”), hunting a cell of Skrull “terrorists” led by talos. The conflict is a series of skirmishes, from the planet Torfa to Earth in the year 1995. The key turning point is Carol's discovery of her own past and the true nature of the Skrulls. She learns from Talos that they are not invaders but homeless survivors. The central “battle” of this war is not between two fleets, but for control of Mar-Vell's light-speed engine, the Skrulls' only hope for escape. The climax sees a fully-powered Captain Marvel single-handedly destroying Ronan the Accuser's approaching fleet, forcing the Kree to retreat from Earth.

Unlike the comics, where the war rages on, the MCU conflict largely concludes for the main players at the end of Captain Marvel. Carol Danvers vows to find the Skrulls a new home, and leaves Earth with them to begin the search. In the post-credits scene of Spider-Man: Far From Home, it's revealed that Nick Fury has begun working with Talos and the Skrulls, using their shape-shifting abilities and advanced technology to protect Earth, laying the groundwork for the S.W.O.R.D. organization. However, the Disney+ series Secret Invasion reveals the dark underbelly of this aftermath. Decades have passed, and Carol's promise has gone unfulfilled. A radicalized faction of Skrulls, led by Gravik, has grown disillusioned and now seeks to claim Earth for themselves by inciting a global war and replacing key human leaders. The MCU's Kree-Skrull War, therefore, is not an endless stalemate but a catalyst that creates a new, more insidious terrestrial conflict born from a broken promise.

A militaristic, authoritarian empire with a rigid caste system, based on the planet Hala. They are characterized by their blue skin (though a “pink-skinned” minority exists, often treated as second-class citizens) and their fanatical devotion to the Supreme Intelligence.

• Key Figures:
  • Supreme Intelligence: The bio-organic supercomputer that rules the Kree Empire, composed of the preserved brains of the greatest Kree minds. In the comics, it is a manipulative entity playing a long game for Kree evolutionary dominance. In the MCU, it's a more direct antagonist that controls Carol Danvers.
  • Ronan the Accuser: A high-ranking member of the Accuser Corps, the Kree's fanatical military judiciary. He is a xenophobic zealot who views any non-Kree as inferior. His role in both the comic storyline and the MCU film is that of a primary military antagonist.
  • Captain Mar-Vell: A celebrated Kree hero who, in the comics, is sent to spy on Earth but becomes its champion. He is the central heroic figure of the comic book war. In the MCU, Mar-Vell is gender-swapped to be a female scientist who betrays the Kree to help the Skrulls.
  • Yon-Rogg: Carol Danvers's commander in the Kree Starforce and her primary nemesis in the MCU. He is responsible for her amnesia and manipulation. In the comics, he is a long-standing rival of Mar-Vell.

A vast, decadent empire built on conquest and infiltration, ruled from the planet of Tarnax IV (until its destruction by Galactus). Their natural ability to shapeshift makes them masters of espionage and psychological warfare.

• Key Figures (Earth-616):
  • Emperor Dorrek VII: The ruler of the Skrull Empire during the Avengers storyline, portrayed as an arrogant and ruthless leader.
  • Princess Anelle: Dorrek's daughter, who falls in love with Captain Mar-Vell and secretly bears his child, the future Young Avenger Hulkling.
  • Kl'rt the Super-Skrull: The first and most famous Super-Skrull, a genetically engineered warrior with the powers of the Fantastic Four. He is a fierce patriot and a recurring nemesis for Earth's heroes.
• MCU Distinction: The MCU's primary Skrulls are not an empire but a refugee group. Their key figure is Talos, a charismatic and weary leader who desires only peace and a home for his people. This portrayal is a near-total inversion of the classic Skrull identity.

The prime defenders of Earth, whose roster during the war included captain_america, iron_man, thor, vision, scarlet_witch, Quicksilver, and Goliath (Clint Barton). They acted as the story's moral compass, fighting to protect a world that was simultaneously beginning to fear and reject them. The war was a defining moment for the Vision, whose exploration of the Kree Sentry on a remote island forced him to confront his artificial nature and his burgeoning humanity.

The human linchpin of the comic's finale. A former sidekick to the Hulk and Captain America, his bond with Captain Mar-Vell (they shared a molecular space, swapping places via the Nega-Bands) placed him at the center of the conflict. His ultimate role as the vessel for the Destiny Force makes him arguably the single most important individual in the entire storyline, a classic Marvel trope of an ordinary human wielding extraordinary cosmic power.

The Kree-Skrull War is more than just a storyline; it's a foundational text whose influence permeates the entire Marvel Universe.

Before this story, most Marvel conflicts were Earth-bound. The Kree-Skrull War was one of the first narratives to treat the wider universe as a genuine setting for drama, politics, and war. It established the Kree and Skrulls as pillar alien races and set the standard for future cosmic epics like The Infinity Gauntlet, Annihilation, and War of Kings. Its multi-issue, interconnected format was a precursor to the modern “event comic.”

Roy Thomas infused the story with powerful social commentary. The “Committee to Gain Control of Super-Humans,” led by the duplicitous Senator H. Warren Craddock (a disguised Skrull), was a clear allegory for the House Un-American Activities Committee (HUAC) and the anti-communist paranoia of the McCarthy era. This subplot saw the Avengers publicly vilified and forced to justify their existence, tapping into the counter-culture sentiment of the early 1970s and exploring themes of civil liberties versus national security.

A key theme of the comic version is the futility and self-perpetuating nature of the conflict. There are no “good guys.” The Kree are fascist eugenicists, and the Skrulls are treacherous imperialists. Earth is just a piece of strategic territory, and its inhabitants are expendable. This grim, morally ambiguous portrayal was sophisticated for its time and stands in stark contrast to the clearer good-versus-evil narrative presented in the MCU's adaptation. The war is not an event with a clean resolution; it's a permanent state of the universe.

The paranoia engendered by Skrull infiltrators in the Kree-Skrull War never truly left Earth's heroes. The knowledge that anyone, anywhere could be a Skrull in disguise was a seed that writer Brian Michael Bendis would cultivate decades later into the full-blown Secret Invasion event. The formation of the Illuminati in the immediate aftermath of the war was a direct response to this threat, a secret pact to do what was necessary to protect Earth—a decision that would lead to its own dark consequences.

The Kree-Skrull War's iconic status has led to its adaptation in various forms, with each version re-interpreting the core conflict.

As detailed above, the MCU's primary adaptation occurred in Captain Marvel and its fallout was explored in Secret Invasion. The most significant changes were:

• Making Carol Danvers the central protagonist instead of Mar-Vell.
• Re-framing the Skrulls as sympathetic victims of Kree genocide.
• Removing the Avengers and the Earth-based political subplot entirely.
• Condensing the galaxy-spanning war into a more contained, personal story about identity and memory.

The most faithful adaptation of the original comic storyline appeared in the critically acclaimed animated series The Avengers: Earth's Mightiest Heroes (2010-2012). The season two arc directly adapted the comic plot, featuring Captain Mar-Vell, the Super-Skrull, the abduction of the Avengers, the political paranoia on Earth, and the ultimate climax with the Destiny Force. It is widely regarded by fans as a stellar and accurate retelling of the classic epic.

While no game has been a direct adaptation of the Kree-Skrull War, the conflict serves as a frequent backdrop.

• In games like the Marvel: Ultimate Alliance series, Kree and Skrull soldiers often appear as enemy factions.
• In the tactical RPG Marvel Strike Force, many Kree and Skrull characters are playable, and their lore often references the ongoing war.
• The conflict is a background element in the story mode for Marvel vs. Capcom 3: Fate of Two Worlds, where Doctor Doom captures Skrull warriors for his army.
