A humanoid alien race from the Mass Effect video game universe.

The kett are a hostile race encountered in the Andromeda galaxy. They have been shown to be highly militaristic, and look down on other species, considering them lesser beings.
In lore, there are no visible distinctions between "male" and "female" kett of the same type.
Kett possess no reproductive organs, and they reproduce only through an artificial process called “exaltation”. It is speculated that exaltation arose long ago in kett history when their genetics reached a point of stagnation, leaving the species unable to breed through natural means. The kett began adding beneficial genes from other species into their own genome in order to continually improve themselves. Kett mastery over genetic manipulation enabled them to develop a serum to rapidly convert other species into obedient kett, which became the basis for exaltation. To build an army or replenish their numbers, kett simply capture members of other species and transform them through exaltation. Species that have been subjected to exaltation include the challyrion, who become wraiths, and the angara, who become Chosen and Anointed.
