Kree - Biology

Biology

True Kree resemble humans almost exactly, with the exception of blue skin. Kree have a higher strength level than that of a human, and require more nitrogen to breathe comfortably. Kree bodies are adapted to environmental characteristics on Hala that are un-Earthlike: they have a higher gravity and a higher concentration of nitrogen in the atmosphere. Under Earth's lesser gravity their strength and speed increase. However, they cannot breathe in Earth's atmosphere without using a chemical, "breathing formula", or artificial life-support devices.

The original Kree had blue-colored skin, but a second racial group with pink skin resembling that of human Caucasians emerged over the millennia. Presently, the blue-skinned "purebred" Kree are a small, but powerful, minority. Pink Kree are much more durable than their blue racial brethren.

Adult Kree range (typically) from between 5 to 8 feet (1.5 to 2.4 m) tall. Some female Kree can physically influence men, and a few can even drain the life force of others.

The Kree were an evolutionarily 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. 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. The Kree value what they consider to be their genetic purity, to such an extent that reproduction outside of the species is a strict taboo. In the Kree empire it is a crime for a male non-Kree to impregnate any Kree.

The Kree race has produced individual super-humanoid beings, either through natural mutation, genetic engineering, or cyborg technology, including Captain Mar-Vell, Ultimus, Shatterstar, Shatterax, Korath, and others.

The Supreme Intelligence attempted to jumpstart the evolutionary process of the Kree. Through a series of events discussed below during Operation: Galactic Storm and the Destiny War, 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.

This new brand of evolved Kree, called Ruul, have a grayish skin tone and many shoulder-length tentacles atop their heads. Individuals possess the ability to 'will' adaptation to different environments, spontaneously developing the ability to breathe underwater, fly, or whatever their circumstances require.
