The Kree race has produced individual super-humanoid beings, either through natural mutation, genetic engineering, or cyborg technology, including Captain Mar-Vell, Ronan the Accuser, Ultimus, Shatterax, Korath, and others.
Through a series of events discussed below during Operation: Galactic Storm and the Destiny War, it arranged for a large number of its 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.
[22] While the Celestials went on to spawn the Kree born Eternals, it was the Progenitors, a race of universal gardeners and cosmic scientists that made their home at the far end of the cosmos within the heart of a lone star, who through the introduction of the Prima Materia which the Progenitors mine and process on their World Farm called The Primagen, were able to force evolve the cro-magnon Kree race into the cosmic conquerors that they are today.
A small minority, like the Priests of Pama, practice a pacifist Cotati religion, but this is forbidden (early Captain Marvel stories mentioned an 'idol' called Tam-Borr and a 'fabricated' god named Zo, whom Mar-Vell served between issues 11 and 15).
Leaders of the Kree have included the Supreme Intelligence, Clumsy Foulup, Nenora, Zarek, Ael-Dan and Dar-Ben, Phae-Dor, Tus-Katt, Morag, Ronan the Accuser, and—most recently—Black Bolt of the Inhumans.
The Skrulls at the time were attempting to start a galactic empire of their own, this one based on free trade, and they landed on Hala to help the barbaric natives advance to the point where they could join.
The permanent ruler was the organic computer-construct called the Supremor (or Supreme Intelligence), an immense computer system to which the preserved brains of the greatest intellects of the Kree race have been linked.
In ultimate comics, they make use of nanomolecular shapeshifting battle armor with advanced genetic tailoring capabilities which can harness thermonuclear to cosmological force as both weaponry and power source.
[35] The Skrulls proposed a test which involved taking members of each race to distant planetoids, with supplies for one year, and then returning at the end to judge what each group had created.
In its haste, however, the Supreme Intelligence failed to download the full data packet, and five worlds that were seeded escaped the slaughter: Badoon, Centaurians, Dire Wraiths, Kymellians and early humans.
[37] As the war dragged on, the Supreme Intelligence accrued more political power and responsibility until finally it was elected as absolute ruler of the Kree and came to be worshipped.
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.
Armed with godlike powers, Rick froze both Kree and Skrull forces, allowing the Intelligence to re-establish control over his people and bring the war to a halt.
Due to the large amount of radiation of the Nega-bomb, the remaining Kree slowly began evolving which was sped up through the machinations of the Supreme Intelligence and the Forever Crystal until they transformed and renamed themselves into a new species: the Ruul.
Under the ruse of being a "new" spacefaring species from beyond charted space, the race orchestrated the events of Maximum Security that temporarily turned Earth into a prison.
[46][47] The machinations of the Supreme Intelligence were undone when a cosmically empowered Genis-Vell, son of Mar-Vell, restored the Kree race to its original form when he destroyed and recreated the universe.
[volume & issue needed] After the assassination of former Empress Lilandra, the Kree launch a T-Bomb powered by Black Bolt's voice, intended to end the war swiftly and decisively.
[59] Once after initial failure, earth's mightiest are eventually successful in the acquisition of its essence, however, Protector betrays the team and hands it to the Supremor as per his mission directive.
[61] A secret group working around the Kree hierarchy through Plex like mind control would later use the power of the cosmic force in conjunction with the M'Kraan Crystal to revitalize the original Captain Mar-Vell.
This plan failed as the Vision emitted a counter broadcast to said grand nephew's unique telepathic abilities controlling everyone on Hala, as the father committed suicide before killing his own son, The Kree homeworld was spared when Captain Marvel sacrificed his own life and the Phoenix energies sustaining him as the entity came to take it back.
[70] It is revealed that at some point the Supreme Intelligence had sent a Kree contingency away to explore and chart the Universe in order to find purchase and grow the name of Hala throughout the stars.
He accepts the offer which was to become the new ruler of the Kree-Skrull Alliance, adopting the mantle of "Dorrek VIII," and beginning the preparations of invading the Earth for "the final war.
"[76] General G'iah and her daughters named Alice, Ivy, and Madison obtain a sample of Cotati from a lab while explaining the history of the Kree and the Skrull's feud.
[193] The Ultimate Captain Marvel (Mahr Vehl) is a Kree spy on Earth, surgically altered to appear human, as well as having an arsenal of defensive cybernetically implanted weapons, and belongs to a family said to have descended from Hala.
[196] In Ruins, set in a universe where everything went wrong, when a Kree fleet led by Mar-Vell were going to invade Earth, they discovered the body of Silver Surfer, whose Power Cosmic was released negating the ships' cloaking.
agent Phil Coulson discovers a blue-skinned corpse in a secret, underground facility called the Guest House while searching for the source of the regenerative GH-325 serum.
[200] In season 2 episodes "...Ye Who Enter Here", "What They Become", and "Who You Really Are", it is revealed that a rogue Kree faction visited Earth as part of their experiments to create genetically altered soldiers.
According to Raina, in contrast to others believing they were acting to conquer or destroy humanity, the Kree created the Diviners for the purpose of engineering Inhumans while wiping out those the relics deem unworthy of the process.
Running afoul of Coulson's team and Sif, whose memory he temporarily robbed with his truncheon, Vin-Tak learned that Skye was an Inhuman and attempts to kill her.
[211][212] Pace and Hounsou reprise their roles as Ronan and Korath, and are joined by Jude Law as Yon-Rogg, Gemma Chan as Minn-Erva, Algenis Perez Soto as Att-Lass, and Rune Temte as Bron-Char, who are members of the Kree military team Starforce.
