Kree
Formerly one of the three great Empires, the Kree are a blue-skinned race of warriors. There are two strains of Kree: blue-skinned and white-skinned. The blues have always been the dominant race, as the whites are the results of hybridization with other species in an attempt to bring mutative genes into the Kree gene pool. Aside from skin color, blue Kree look almost exactly like humans in both genders. White Kree are nearly indistinguishable from humans upon visual inspection. However, one biological difference is that Kree have two bladders, so never get into a drinking contest with one!
 The Skrull Judgment |
Millions of years ago, the Kree were a semi-barbaric race just emerging into civilization. At that time, they shared their home planet of Hala with another sentient species, the tree-like Cotati. When the more advanced (and peace-loving) Skrulls came to Hala, they agreed to ally with the more worthy of the two species. To test this worthiness, the Skrulls transported a sample of each species to Earth's moon, on which each group was to show their abilities and skills. The Kree built a magnificent city, but the Cotati coaxed a portion of the long-dead moon back to life, creating the region today known as the Blue Area of the Moon. The Skrulls voted for the Cotati, and in a fit of rage, the Kree killed the Skrulls and the Cotati, launching into a war of extermination of the Cotati.
As a result, the Kree Empire clashed for millions of years with the Skrulls, until Rick Jones used his latent Destiny Force to stop the war. Thousands of years ago, their scientists developed the race of beings now called the Inhumans to be their super-soldiers in that war, althought their creations evenutally rebelled. Later on, the Kree attacked the Shi'ar Empire, and the Avengers journeyed into space to stop the Kree-Shi'ar war because the alien armies were using Stargates powered by Earth's Sun, which was endangering the entire Solar System. The Kree are ruled by the Supreme Intelligence, a giant conglomeration of the minds of billions of Kree.
Their greatest champion was the warrior Mar-Vell, known on Earth as Captain Marvel. Once, when Captain Marvel was on Earth fighting a Kree villain, a NASA employee named Carol Danvers got between him and a blast from a Kree waepon called the Psyche-Magnetron. The blast turned Danvers part Kree and also bequeathed to her Marvel's powers of flight, strength and invulnerability, along with a precognitive 7th sense and the ability to fly in space unprotected. (These powers were later permanently absorbed by Rogue.) Marvel fought many foes in his time, and was respected by many heroes. Unfortunately, he contracted cancer and succumbed after a dignified and heroic fight with the disease.
 The Supreme Intelligence |
In the midst of the war, the Supreme Intelligence manipulated events so that the Shi'ar would create a Nega-bomb, which would destroy most of the Kree. While Lilandra discovered the evil plan, Supremor (the Supreme Intelligence) had some Skrull agents steal the bomb and detonate in on Hala, the Kree Homeworld, in an explosion that killed millions of his people. Supremor hoped that this cataclysm would force his people to begin evolving again, which they had stopped doing long ago. Some Avengers, incensed by this horrific act (and secretly manipulated by Kang) went to kill the Intelligence, and the Black Knight seemingly accomplished the feat. In reality, the Intelligence survived, and was relocated to Earth's Moon where he could study Earth and possibly prepare to invade it. Meanwhile, the Kree Empire was conquered by the Shi'ar and incorporated into its Empire. Lilandra brought some of the X-Men, including Professor Xavier to Hala for her coronation. While, there, the X-Men uncovered a terrorist plot and saved Lilandra and her entourae, with the help of one of the terrorist's leaders. However, as Lilandra had just proclaimed her sister Deathbird Regent of Hala, she could not stop the terrorist who assisted them from being arrested, leading to a rift between her and Xavier. The Starjammers recently got involved with resettling Kree fugitives on a collection of anarchist worlds called the Clench. They even added a Kree navigator to their ranks, a young man named Keeyah.
 Ru'ul forms: Diplomat, Warrior, Worker (clockwise from top) |
Recently, a group of aliens called the Ru'ul convinced the Shi'ar that humanity was dangerous and meddlesome and spearheaded a vote to turn Earth into a prison planet. It was soon revealed that the Ru'ul were actually the Kree, who had been given new abilities to evolve and devolve themselves by touching the Forever Stone. This was all part of the Supreme Intelligence's plan to jump-start his people's evolution. When the Ru'ul were revealed to be the Kree, their plan to besiege Earth was dismantled. As the Ru'ul, they could choose to be intelligent "diplomats," clever "warriors" or brutish but extremely strong "workers." What became of the unmutated Kree is still unknown.
