Origins and prehistory

The Xorrians and the Progenitors

Over six million years ago, the Xorrians allegedly spawned the Kree (along with all humanoid life-forms, such as Skrulls and Humans) from their own DNA.[5]

The Celestials and the Progenitors

Two distinct groups of giant godlike aliens experimented on the early Kree:

The Skrulls

A million years ago,[8] a race of humanoid reptiles called the Skrulls came upon prehistoric Hala. At that time the Skrulls were a largely peaceful space-faring race, and they set about educating the natives to the point where they could join their trading empire. However, Hala was home to two equally intelligent races, the Kree and the Cotati.[3]

The Skrulls proposed a test to determine the worthier race between the Kree and the Cotati. Taking members of both races to a distant planetoid in another galaxy, the Blue Area of the Earth's Moon, the Skrulls created an arena and bid the two races to use the resources they had to create something of worth. The Skrulls then left. The Kree constructed a magnificent city, while the Cotati created a beautiful garden.[3]

A year later the Skrulls returned to judge the two races and found the Cotati's accomplishment the worthier. Enraged, the Kree killed the Skrulls and the Cotati and seized the Skrulls' star-ship. They used the ship to return to their native planet, then set about deciphering the technology of the star-ship. Within a hundred years of acquiring interstellar technology from the Skrulls, the Kree empire began to spread throughout the Greater Magellanic Cloud.[3]

Kree Empire & Kree-Skrull War

The Kree launched an attack upon the Skrull Empire and the peaceful Skrulls were again forced to become warlike to defend themselves. The Kree-Skrull War would continue for hundreds of thousands of years.[3]

At the same time the Cotati on Hala were almost driven to extinction by the Kree. However, a small handful of Kree, the pacifist Priests of Pama, hid and kept safe a group of Cotati. Eventually these Kree began worshiping the Cotati that they had kept sheltered. To further hide and keep them safe, the priests relocated the surviving Cotati throughout the universe.[9]

About 250 years later the Kree Science Council, aware that the Skrulls had once created an incredibly powerful weapon called the Cosmic Cube, designed a cybernetic/organic supercomputer called the Supreme Intelligence (sometimes referred to by the honorific "Supremor") to help them in creating a Cube. When the computer became functional, it determined that a Cosmic Cube would be too dangerous to construct and refused the Science Council's request. The computer was then used simply in an advisory capacity.[citation needed]

At the beginning of the Kree-Skrull War, millions of years ago in Earth time, the Kree established a station on the planet Uranus, a strategic position between the Kree and Skrull Empires. Through their work at this station, they discovered that sentient life on nearby Earth had had genetic potential invested in it by the alien Celestials. Intrigued, the Kree began to experiment on Earth's pre-humans.[10]

The Inhumans' Creation

Their goal was apparently twofold — to investigate possible ways of circumventing their own evolutionary stagnation, and to create a powerful mutant race of soldiers for use against the Skrulls. However, although their experiments were successful in creating a strain of humanity with extraordinary and diverse abilities, the Kree abandoned their experiment for reasons which are not yet clear.[citation needed]

Their test subjects, eventually dubbed the Inhumans, went on to form a society of their own, which thrived in seclusion from the rest of humanity. Their city Attilan has frequently been relocated and rested for a long time in the Blue Area of the Moon. The Kree abandoned the project eventually, but stationed a giant surveillance robot, Sentry 459, on a small South Pacific island. The Fantastic Four's unwary awakening of the long-dormant Sentry, alerted the Kree to Earth's advanced state of evolution. The Sentry's destruction brought the Kree official Ronan the Accuser, with the intent of passing judgment on those who "murdered" the outpost guard; his own defeat increased Kree scrutiny of Earth.[11]

Over time, and as the war with the Skrull dragged on, the Supreme Intelligence gradually accrued more and more political power and responsibility until finally it was elected as absolute ruler of the Kree. Eventually, the Supreme Intelligence came to be worshiped and an organized religion built up around.[12]

The Earth's importance as a strategic beachhead became apparent when the Avengers became involved in the latest round of Kree-Skrull hostilities. The Skrull were revealed to have been infiltrating human society in an effort to control America's political infrastructure, using their shape-shifting abilities to replace key political figures. In the meantime, the Kree were reestablishing cultural ties with the Inhumans, ostensibly for the purpose of technological exchange, although their true intentions turned out to be far more sinister.

At this point, Captain Marvel, former hero of the Kree Empire, approached the Avengers with evidence that renegade elements within the Kree Hierarchy (led by Ronan the Accuser) were planning to 'erase' humanity through the use of exotic technology. This particular scheme was foiled by Marvel and the Avengers (comprised, at that time, of Goliath, Quicksilver, the Scarlet Witch, the Vision, Yellowjacket, the Wasp, and eternal side-kick Rick Jones) but it proved to be only the tip of the iceberg.

As the war escalated and Earth's position became increasingly precarious, the original Avengers (including Thor, Iron Man and Captain America) were recalled to active service after a Skrull scouting party (led by interstellar menace the Super-Skrull) managed to abduct Marvel, Quicksilver and the Scarlet Witch. The Skrull also attempted to destroy the Inhumans' Great Refuge with a nuclear-level incendiary device, but failed when the Avengers intervened. This was the group's first inkling that an interplanetary war was being fought over possession of the Earth. During the ensuing conflict, the Skrull took his prisoners back to the Skrull homeworld, leaving the remaining Avengers to pick up the pieces and reform their tattered forces.

The conflict worsened when the Avengers began to understand the scale of the war erupting all around them. Setting off in pursuit of their kidnapped allies, they discovered a vast 'Skrull' armada en route to devastate the planet Earth; an equivalent Kree fleet poised to annihilate the Skrulls; and a full-scale insurrection breaking out between the Supreme Intelligence and Ronan the Accuser. All sides were determined to either invade or decimate the Earth in order to prevent it falling into the 'wrong' hands. Led by Thor, Iron Man and the Vision, the Avengers launched an attack on the Skrull flagship, somehow managing to turn back the fleet after a desperate battle (during which Goliath was deemed to be MIA and presumed dead).

The war came to a close when the Supreme Intelligence managed to bring Rick Jones into his presence. The Supreme Intelligence had been usurped by Ronan the Accuser, but (as he explained to Rick in retrospect), he was still capable of channelling his powers through an agent. While the Supreme Intelligence cared little for the fate of Earth and its inhabitants, he recognized that the Kree-Skrull war was futile, and temporarily altered Rick's DNA to release his 'full evolutionary potential.' Armed with godlike powers, Rick literally froze both Kree and Skrull forces in mid-stride, allowing the Supreme Intelligence to re-establish control over his people and bring the war to a halt.

The effort proved too much for Rick's fragile human physiology; as he collapsed lifeless to the floor, the Supreme Intelligence teleported the remaining Avengers to his side to witness his grim sacrifice. The irony was not lost on the assembled heroes, who reflected that a frail teenaged boy had succeeded where all of their collective might had failed. The final act in the cosmic tragedy was played out by Captain Marvel, who - understanding the debt owed by all of them - agreed to merge his life-force with Rick's body, bringing the boy back from the brink of death at the cost of his own existence.[13]

At several points in the years after the end of the first Kree-Skrull War hostilities were said to have broken out again between the two empires. It is unclear how serious these conflicts were though they were often referred to as "wars".[citation needed] The most significant of these instances came when the Skrulls lost their ability to shapeshift, and a Skrull Warlord provoked new hostilities. During this war, the Supreme Intelligence was incapacitated by the Silver Surfer who removed the Soul Gem which the creature used to maintain peaceful balance between its blue and pink Kree components. Afterwards, Nenora, a Skrull spy in the guise of a high ranking Kree official, took command of the Kree empire. The war ended with Nenora being exposed as a Skrull. Leadership of the Kree was assumed for a time by an alien named Clumsy Foulup.[14] Another significant conflict arose during the Infinity Gauntlet event when the machinations of Thanos led to the sudden elimination of half the universes lifeforms. Unaware of Thanos' role in the disappearance, the Kree and the Skrull blamed each other and temporarily renewed fighting.[15]

Not long after the conflicts with the Skrull ended, the Kree again found themselves embroiled in a war, this time with the Shi'ar Empire. This war was much shorter, and was engineered by the Skrull and the Supreme Intelligence.[16] The Avengers of Earth became involved in the conflict and their involvement (primarily between the Vision and Wonder Man) inadvertently set off a chain of events which led to a Nega-Bomb being detonated in Kree space. The bomb explosion, in which negative energy was released into space causing an extremely powerful explosive and radioactive reaction, devastating the Kree empire and killing ninety eight percent of the entire Kree population. This act of extreme genocide led to the Kree's surrender to the Shi'ar. The Supreme Intelligence was eventually revealed as being ultimately responsible for the bomb's detonation, the whole thing being a bid to kickstart the Kree race's genetic development.[17].

A Kree territory was then annexed by the Sh'iar, with Majestrix Lilandra naming her sister Deathbird as the territories' administrator. Deathbird has since abandoned this post and it appears that the Kree Empire has, at least in some part, been reestablished.[citation needed]

The remaining Kree were evolved into the Ruul through the machinations of the Supreme Intelligence.[18][19]

The Kree have since returned to prior form.[20][citation needed] The consensus is that when Captain Marvel convinced Entropy (son of Eternity) to destroy the universe, but then to recreate it almost exactly alike, it caused some 'discrepancies' (such as Genis-Vell's mother being still alive, and having a grownup daughter).[citation needed]

Destruction of Hala

With the resurgence of the Black Vortex, a powerful item capable of unleashing the cosmic potential of whoever used it, the Kree attempted to destroy it. The Supreme Intelligence sent Ronan and the Accuser Corps to take it from their current possessors, the cosmically enhanced Gamora, Beast and Angel.[21]

In retaliation, the three cosmically-enhanced beings assaulted Hala.[22] The Accuser Corps tried to fight off their attackers, but were notably overpowered. After being denied by the Supreme Intelligence to use the power of the Black Vortex to fight back, Ronan the Accuser disobeyed him, and submitted to its power, ensuring a successful defense for the Kree homeworld, and forcing Gamora, Beast, and Angel to flee after the latter was knocked down.[23]

Once the dust settled, the Kree attempted to get rid of the Black Vortex once more. However, they were attacked by Mister Knife and the Slaughter Lords, another party interested in the Vortex. Taking advantage of the state of frailty in which Hala was left, he used all the firepower of his flying fortress to destroy the planet. The Supreme Intelligence demanded his Accuser Corps to escape, while he remained in Hala and perished.[24]



Kree philology originally developed through heavier gravity, higher nitrogen-to-oxygen air content, and a form of dependency centered around the Cotati (a highly intelligent and extremely mature species of telepaths in-tune with nature). Though as intelligent the Kree's were ignorant eventually ignoring nature, forging towards technology advancement then millennia of War.[citation needed]

Outwardly the Kree resemble humans, with little exception through skin color or modified genetics. Denser skin with increase muscles flexibility give the Kree endurance, durability, and stamina-- twice the level of humans. They also have "duplicates" of several internal organs,[25] and usually require more nitrogen to breathe comfortably on earth.[citation needed]

Evolutive stagnation

The Kree were an evolutionary stagnant race. This was due to a single member of the Kree race attempting to gain control of the Crystal of Ultimate Vision. This unnamed Kree found the crystal, but attempted to use it to become akin to a god, with powers as of those of the Phoenix Force. As punishment, the crystal "genetically froze their evolution in place" allowing the rest of creation to pass them by.[26]

Although, it was stated that the Kree produced superhumanoid beings through natural mutation.[27]

The explosion of the first Nega-Bomb in the Kree Empire had the survivors' genetic structures to quickly mutate and adapt to the radiation, allowing the Kree to escape their evolutionary dead end by changing their DNA and allegedly granting them unlimited potential.[16]


Somehow, a group of pink-skinned Kree managed to produce a mutant Kree, Tsu-Zana, in order to overthrown the domination of both Shi'ar and blue-skinned Kree, as the savior. She rejected that destiny and is still residing on Earth under the codename Ultra-Girl.[28]

Mutant Cataracts

On Earth-9591, Mar-Vell and his Kree contingent were irradiated by a nuke. Mar-Vell subsequently developed a mutant cataract.[29]


Humans and Eternals

The Kree have shown to be reproductive via cross-breeding with humans normals and Eternals.

Deathbird's and Vulcan's child was infused with Kree genes.[30][verification needed]


Hulkling is also a Skrull-Kree hybrid, conceived via natural ways.[31]


The Kree are vulnerable to many fatal diseases, among them Blackgorge, Betath's Plague, the Wasting.[32]

They are maybe also afflicted by cancer, whom they call blackend.[33]

On Earth-9591, Mar-Vell and his Kree contingent were irradiated by a nuke. Mar-Vell subsequently developed a mutant cataract.[29]



The Blue-skinned Kree represent the Archetype and the base of the Kree species.[citation needed]

"Seventh Sense"

Kree women possess the potential for psychic abilities of various kinds, collectively referred to as a "seventh sense". This psychic potential has manifested as clairvoyance, precognition, or even lethal attributes. Some Kree women can reach into the mind of male-sex species to manipulate their desires or drain another's life force completely. Kree technology has since been created to discover and remove the powers surgically, and technorganic Bloodhounds were used to track down female reaching the adult age with those abilities.[34]


In an attempt to further their development, some Kree bred with other species, producing the "pink-skinned" Kree, who are similar in appearance to Caucasian humans. These pinks (also called "whites") eventually outnumbered the blue-skin Kree.[citation needed]


The Supreme Intelligence arranged for further advancement of the Kree. Through a series of events, he arranged for a large number of his people to be irradiated with a Nega-Bomb (killing 90% of the Kree), and then artificially sped up their evolution by means of an artifact called the Forever Crystal,[16][35] effecting countless millenia of evolution in mere moments.[36]

This new brand of evolved Kree, called Ruul, have a grayish skin tone and many shoulder-length tentacles atop their heads. Individuals possessed the power of "forced evolution", the ability to "will" adaptation to different environments, spontaneously developing the ability to breathe underwater, fly, or whatever their circumstances require.[18][36]

Eternals and Deviants

The Celestials have at some point, as many others species visited and modified the ancient Kree genetics. The last and only known Kree Eternal is Ard-Con, alias Ultimus the Demon-Druid. The fate of the Kree Deviants is unknown.[8]

  • Despite the existence of both Kree Eternals and Kree Deviants created by the Celestials,[8] and the similar experiments which were performed on the Kree as those performed on the Skrulls, humans, and Eyungs,[37] the Kree themselves have not been explicitly stated to be granted a latent potential like other species.
  • Kree soldiers appeared during Avengers Disassembled when they attacked the Earth and were driven off by the Avengers. In the process, Hawkeye was killed. But this may not have been the real Kree, as the entire incident was later discovered to be a product of the Scarlet Witch's reality-altering powers.
