====== The Kree ======
===== Part 1: The Dossier: An At-a-Glance Summary =====
  *   **Core Identity: **A technologically advanced, militaristic, and fiercely nationalistic alien empire from the planet Hala, whose eons-long war with the Skrulls and genetic experiments on other races have profoundly shaped the cosmic landscape of the Marvel Universe.**
  *   **Key Takeaways:**
  * **Role in the Universe:** The Kree are one of the three great galactic empires in Marvel lore, alongside the [[skrulls]] and the [[shi'ar_empire]]. They are defined by their rigid military culture, their expansionist policies, and their ancient, intractable conflict with the shape-shifting Skrulls.
  * **Primary Impact:** The Kree are directly responsible for the creation of the [[the_inhumans]] through genetic tampering on early humanity. Their war with the Skrulls has repeatedly spilled over to affect Earth, and their actions led directly to the empowerment of one of Earth's greatest heroes, [[carol_danvers|Captain Marvel]].
  * **Key Incarnations:** In the comics, the Kree are a complex, ancient empire with a sprawling history governed by the bio-computer known as the [[supreme_intelligence]]. In the Marvel Cinematic Universe (MCU), they are portrayed as a more straightforwardly villainous empire of religious zealots, with their war against the Skrulls being a central plot point in //Captain Marvel//.
===== Part 2: Origin and Evolution =====
==== Publication History and Creation ====
The Kree made their first, albeit subtle, appearance in **//Fantastic Four// #64 (July 1967)** with the introduction of the Kree Sentry, but the race itself was properly introduced and named in the following issue, **//Fantastic Four// #65 (August 1967)**. Created by the legendary duo of writer [[stan_lee|Stan Lee]] and artist [[jack_kirby|Jack Kirby]], the Kree were initially conceived as formidable antagonists for Marvel's First Family. Their first major representative, [[ronan_the_accuser|Ronan the Accuser]], embodied their core traits: technologically superior, physically imposing, and utterly contemptuous of "lesser" species like humans.
The creation of the Kree occurred during the height of the Silver Age of comics, a period of immense creative expansion for Marvel. They served as a perfect cosmic counterpoint to the more insidious, subversive threat of the Skrulls, who had been introduced years earlier. While the Skrulls represented a Cold War-era fear of infiltration and "the enemy within," the Kree represented the threat of a monolithic, expansionist military power. Their development culminated in the landmark //Kree-Skrull War// storyline in the pages of //Avengers// in the early 1970s, which cemented their status as a cornerstone of the Marvel cosmic mythos.
==== In-Universe Origin Story ====
The origin of the Kree Empire is an ancient tale of ambition, jealousy, and war, differing significantly between the comics and the cinematic universe.
=== Earth-616 (Prime Comic Universe) ===
Millions of years ago, the planet Hala was home to two sentient species: the humanoid, barbarian Kree and the peaceful, plant-like Cotati. At this time, the highly advanced, shape-shifting Skrull Empire was traversing the galaxy, uplifting "worthy" primitive races with their technology and knowledge. Upon arriving at Hala, the Skrulls were unable to choose between the two species. They devised a test.
The Skrulls transported groups of both Kree and Cotati to Earth's moon, providing them with the necessary resources and one year to create something of worth. The Cotati cultivated a magnificent, complex garden. In contrast, the Kree, led by General Morag, constructed a massive, technologically advanced city. When the Skrulls returned, they judged the Cotati's creation to be superior in its nobility and ingenuity. Enraged by this perceived slight, Morag and his Kree followers slaughtered the Skrull delegation and the Cotati. They commandeered the Skrull starship, returned to Hala, and used the reverse-engineered technology to build their own fleet, beginning a genocidal campaign against the remaining Cotati.
This act of aggression was the genesis of the Kree Empire and the spark that ignited the Kree-Skrull War, a conflict that would rage for millennia and define both civilizations. Driven by a desire for galactic conquest and a need to prove their superiority, the Kree established a vast empire centered on Hala. However, their evolution began to stagnate. To counteract this genetic dead-end, Kree scientists traveled the galaxy, experimenting on primitive races to create living weapons. One such experiment on early //Homo sapiens// on Earth resulted in the creation of the Inhumans. The Kree eventually abandoned the project, but their creation would grow into a powerful society of its own.
Over time, the Kree developed the Supreme Intelligence, a massive bio-organic computer created from the preserved brains of the greatest Kree minds, to guide their civilization. It became their absolute ruler, a living god-computer whose logic was paramount.
=== Marvel Cinematic Universe (MCU) ===
The MCU presents a more streamlined and morally unambiguous origin for the Kree's central conflict. As detailed in the film //Captain Marvel// (2019), the Kree Empire is a powerful, authoritarian society at war with the Skrulls. However, the context of this war is drastically different. In this continuity, the Kree are unequivocally the aggressors, having destroyed the Skrull homeworld, Skrullos, and embarked on a genocidal campaign to hunt the surviving Skrull refugees across the galaxy.
The Kree are ruled by the Supreme Intelligence, an artificial intelligence that takes the form of the person most respected by whomever it is communicating with. Their society is dogmatic, with their people taught from birth that the Skrulls are devious, terroristic infiltrators who must be eradicated. Kree warriors, like those in the elite Starforce, are indoctrinated with this belief system.
Their interaction with Earth began when a Kree scientist, Mar-Vell (under the human guise of Dr. Wendy Lawson), defected from the Empire. Believing the war to be unjust, she fled to Earth to develop a light-speed engine that could transport the last Skrull survivors to safety. A Kree Starforce unit, led by Yon-Rogg, tracked her down. In the ensuing confrontation, the engine exploded, imbuing human pilot Carol Danvers with cosmic power. The Kree captured Danvers, wiped her memory, transfused her with Kree blood, and repurposed her as "Vers," a Kree weapon.
The MCU also establishes in //Agents of S.H.I.E.L.D.// that a rogue faction of Kree visited Earth thousands of years ago, experimenting on humans to create super-soldiers they called Inhumans. This project was eventually shut down by the Kree leadership, who viewed the experiments as a failure and a threat, leading them to send a "Reaper" to cleanse the planet of their creations.
===== Part 3: Kree Biology, Society & Technology =====
The Kree are defined as much by their internal makeup and societal structure as they are by their external conflicts.
=== Earth-616 (Prime Comic Universe) ===
==== Biology ====
The Kree physiology is adapted to the high-gravity, high-nitrogen environment of their homeworld, Hala. This grants them several advantages over humans in Earth-normal conditions.
  * **Superior Physiology:** Kree possess superhuman strength, speed, durability, and reflexes, typically being able to lift several tons. Their bodies are denser and more resistant to injury than a human's.
  * **Two Subspecies:** There are two distinct Kree racial groups.
    * **Blue Kree:** Also known as "pure-bred" Kree, they are a numerically small but powerful ruling-class minority. They possess blue skin and are considered the original Kree stock. [[ronan_the_accuser|Ronan]] is a prominent example.
    * **Pink Kree:** The more common subspecies, they are physically indistinguishable from white-skinned humans. This group resulted from ancient Kree interbreeding with other humanoid species in an attempt to kickstart their evolution. [[captain_mar-vell|Captain Mar-Vell]] was a Pink Kree.
  * **Evolutionary Stagnation:** The Kree's primary biological weakness is their stalled evolution. This lack of genetic progress is a source of national shame and paranoia, and it was the primary motivation for creating the Supreme Intelligence and the Inhumans.
==== Society & Culture ====
Kree society is a rigid, militaristic, and collectivist autocracy.
  * **Government:** For millennia, the Kree Empire was an absolute monarchy ruled by the Supreme Intelligence from the capital city of Kree-Lar. Individuality is often suppressed in favor of the "greater good" of the empire, as dictated by Supremor.
  * **Military Structure:** The military is the central pillar of Kree life. Key institutions include:
    * The **Accuser Corps:** The judiciary and enforcers of Kree law, wielding powerful Universal Weapons.
    * The **Starforce:** An elite military unit composed of the Kree's most powerful warriors.
    * **The Kree Public Army:** The vast legions that prosecute the empire's wars across the galaxy.
  * **Xenophobia:** The Kree are intensely xenophobic, viewing most other species as inferior. Their imperialism is driven by a belief in their own manifest destiny to rule the cosmos.
==== Technology ====
The Kree are a Type III civilization on the Kardashev scale, wielding technology far beyond human comprehension.
  * **Weaponry:** The **Universal Weapon** is the signature armament of the Accusers, capable of energy projection, matter manipulation, and force-field generation. They also employ advanced energy rifles and starships.
  * **Travel & Communication:** Kree starships are capable of interstellar travel via warp drives or "stargates." They use **Omni-Wave** technology for faster-than-light communication across their vast empire.
  * **Genetic & Cybernetic Tech:** The **Psyche-Magnitron** was a device capable of turning thoughts into reality, which infamously empowered Carol Danvers. The Kree also created powerful robotic soldiers known as **Sentries** to guard their outposts.
=== Marvel Cinematic Universe (MCU) ===
==== Biology ====
The MCU's depiction of Kree biology is largely consistent, with some key cinematic adaptations.
  * **Strength and Durability:** Kree are shown to be significantly stronger and more durable than humans, as seen with Ronan, Yon-Rogg, and Korath the Pursuer.
  * **Blue vs. Pink:** Blue-skinned Kree are the primary visual representation of the species. Pink-skinned Kree are confirmed to exist through Mar-Vell's human disguise, but they are not shown to be a distinct social class as in the comics.
  * **Unique Blood Properties:** Kree blood has restorative and power-granting properties. A transfusion of Kree blood from Yon-Rogg saved Carol Danvers' life and stabilized her powers. In //Agents of S.H.I.E.L.D.//, the "T.A.H.I.T.I." project used a serum derived from an ancient Kree corpse to resurrect Phil Coulson, albeit with significant side effects.
==== Society & Culture ====
The MCU Kree are portrayed as a society of fanatical imperialists.
  * **Theocratic Rule:** Their society is less of a military autocracy and more of a theocratic state, with the Supreme Intelligence serving as a living god and absolute ruler.
  * **Indoctrination:** Kree citizens and soldiers are heavily indoctrinated into a belief system of Kree superiority and a fanatical hatred of the Skrulls. Questioning the Supreme Intelligence or the state's narrative is considered heresy.
  * **Starforce:** The elite fighting unit is given a prominent role in //Captain Marvel//, serving as the primary enforcers of the Supreme Intelligence's will on off-world missions.
==== Technology ====
MCU Kree technology is visually distinct but functionally similar to its comic counterpart.
  * **Energy Weaponry:** Kree soldiers are equipped with advanced energy pistols and rifles. Starforce members have specialized energy-channeling devices on their wrists.
  * **Starships:** Kree ships range from smaller interceptors like the Helion to massive warships like Ronan's //Dark Aster// and the Accuser battlecruisers. They possess advanced cloaking technology.
  * **Memory and Genetic Engineering:** The Kree demonstrated the ability to manipulate and erase memories, as they did with Carol Danvers. They also use devices to suppress her full power, indicating a deep understanding of energy and biological manipulation. The Light-Speed Engine, based on the Tesseract, was a technology they desperately sought.
===== Part 4: Key Relationships & Network =====
==== Arch-Enemies & Rival Empires ====
  * **The Skrulls:** The most significant relationship in Kree history. Their multi-millennial war is the defining conflict of the cosmic landscape. It has been a cold war, a hot war, and a war of infiltration. The conflict is ideological at its core: the expansionist, orderly Kree versus the adaptable, subversive Skrulls. This rivalry has shaped both empires and frequently drawn in other races, most notably humanity.
  * **The Shi'ar Empire:** The other major galactic power. The Kree and Shi'ar have often been rivals for territory and influence. This rivalry escalated into a full-scale war during //Operation: Galactic Storm//, which saw the Shi'ar, under Empress Lilandra, detonate a Nega-Bomb in Kree space, devastating the empire and killing billions. The Shi'ar then annexed the weakened Kree territory for a time.
  * **Annihilus and the Annihilation Wave:** During the //Annihilation// event, the Kree Empire was one of the primary targets of the interdimensional insectoid army from the Negative Zone. Their defenses were shattered, and much of their territory was conquered, forcing Ronan to work with other cosmic heroes like Nova to repel the invasion.
==== Significant Pawns & Creations ====
  * **The Inhumans:** The Kree's most famous and consequential experiment. Created to be a living weapon army and to solve the Kree's evolutionary stagnation, the Inhumans were abandoned on Earth. They developed their own complex society in the hidden city of Attilan and became a powerful force in their own right, eventually even taking control of the Kree Empire for a time under their king, Black Bolt.
  * **Captain Mar-Vell:** A Kree captain sent to spy on Earth, Mar-Vell grew to love humanity and became its sworn protector, defecting from the Empire and becoming the first Captain Marvel. He is the ultimate symbol of a Kree transcending his culture's xenophobia, a hero to both Earth and, eventually, the Kree people.
  * **Carol Danvers (Captain Marvel):** A human whose DNA was fused with Mar-Vell's in an explosion involving the Psyche-Magnitron. As Ms. Marvel and later Captain Marvel, she is a living bridge between the two cultures. Her immense power, derived from Kree technology, makes her one of the most powerful beings in the universe and a key player in the Kree's modern history.
==== Key Kree Figures ====
  * **[[ronan_the_accuser|Ronan the Accuser]]:** The Supreme Public Accuser of the Kree Empire. A radical traditionalist and military zealot, Ronan is the embodiment of Kree law and might. He has been a villain, an anti-hero, and even a ruler of the empire, but his actions are always guided by a fierce, unyielding devotion to the Kree people.
  * **[[supreme_intelligence|The Supreme Intelligence]]:** The bio-organic supercomputer that ruled the Kree for thousands of years. Composed of the collective consciousness of the greatest Kree minds, it is a being of unfathomable intellect and manipulative cunning. Its primary goal has always been the survival and advancement of the Kree race, often through cold, calculating, and genocidal means.
  * **Yon-Rogg:** A Kree military commander and a persistent rival of Mar-Vell. His jealousy and ambition led to numerous conflicts with Mar-Vell and were indirectly responsible for the creation of Carol Danvers as a superhero. He represents the more personal, petty ambition that can exist even within the Kree's collectivist society.
===== Part 5: Iconic Events & Storylines =====
=== The Kree-Skrull War (Avengers #89-97, 1971-1972) ===
This storyline is arguably the most important Kree-centric event in Marvel history. It elevated a long-simmering conflict into an epic that spanned the galaxy and threatened Earth. The war came to Earth when Captain Mar-Vell was captured by Ronan the Accuser. The Avengers became entangled in the interstellar conflict, discovering Skrull infiltrators on Earth and traveling to the heart of both empires. The storyline revealed the ancient origins of the war, showcased the Supreme Intelligence's manipulative genius, and culminated in the Avengers having to stop the Kree from de-evolving humanity. It established the template for all future Marvel cosmic events.
=== Operation: Galactic Storm (1992) ===
A massive 19-part crossover event, this storyline depicted the brutal, full-scale war between the Kree and the Shi'ar Empire. The conflict was engineered by two Skrulls and secretly manipulated by the Supreme Intelligence itself. The Avengers intervened, trying to broker peace, but were torn apart by an ethical schism when a rogue faction of heroes decided to execute the Supreme Intelligence for its role in the war. The event concluded with the detonation of a Nega-Bomb in Kree space, which devastated the empire and led to its temporary annexation by the Shi'ar. The Supreme Intelligence had secretly allowed this, calculating that the bomb's radiation would eventually restart Kree evolution.
=== Annihilation (2006) & Annihilation: Conquest (2007) ===
While not solely a Kree event, //Annihilation// featured the Kree Empire as a primary victim of Annihilus's invasion. The empire was quickly overrun, forcing Ronan the Accuser, who had been exiled, to reclaim his authority and lead a resistance. In the sequel, //Annihilation: Conquest//, the weakened Kree were targeted by the Phalanx, a techno-organic race led by Ultron. The Kree were assimilated and became the primary antagonists, with heroes like Nova and a new Quasar leading the fight to free them. These events fundamentally reset the cosmic status quo and positioned Ronan as the sole leader of a battered but defiant Kree Empire.
=== War of Kings (2009) ===
Following the events of //Secret Invasion//, the Inhumans, seeking a more secure destiny, left Earth and claimed leadership of the Kree Empire, with Black Bolt as their king. This bold move put them in direct conflict with the Shi'ar Empire, now ruled by the tyrannical mutant Vulcan. The resulting war was a devastating conflict between two of the galaxy's great powers, now led by new rulers. The war ended tragically with the apparent deaths of both Black Bolt and Vulcan, leaving the Kree Empire in a state of flux.
=== Empyre (2020) ===
This event represented the most significant change to the Kree-Skrull dynamic in their entire history. The two ancient enemies finally united under a single banner, forming a new Alliance led by the young emperor Dorrek VIII, also known as the Young Avenger Hulkling—a Kree-Skrull hybrid and son of the original Captain Mar-Vell. Their first act as a united force was to declare war on Earth, believing the planet to be a stronghold of their true, ancient enemy: the plant-like Cotati, who sought to eradicate all animal life in the galaxy. The event ended the Kree-Skrull War for good and established a powerful new galactic player.
===== Part 6: Variants and Alternative Versions =====
  * **Ultimate Universe (Earth-1610):** In this reality, the Kree are a more insectoid, hive-minded race. They are overseen by a leader named Yahn Rgg and have a very different relationship with their Captain Marvel, Mahr Vehl. Mahr Vehl was sent to observe Earth's destruction by the world-eater Gah Lak Tus but, like his 616 counterpart, grew to admire humanity and rebelled to help defend it.
  * **Marvel's Avengers (Video Game, 2020):** In this continuity, the Kree are a looming, unseen threat. It's revealed that a Kree Sentry was buried on Earth millennia ago. The "A-Day" disaster, which released Terrigen Mist over San Francisco and created a new wave of Inhumans, was caused by Captain America destroying a Kree-tech-powered reactor on the Avengers' Chimera helicarrier. The future of this universe hints at an impending Kree invasion.
  * **Avengers: Earth's Mightiest Heroes (Animated Series):** This beloved animated series provided a very faithful adaptation of the Earth-616 Kree. It featured Captain Mar-Vell's mission to Earth, his betrayal of the Kree Empire to protect humanity, and a multi-episode arc adapting the Kree-Skrull War. Ronan the Accuser and the Supreme Intelligence were also key players, closely mirroring their comic book counterparts in motivation and design.
