At the beginning of the Kree-Skrull War, millions of years ago in Earth time, the alien 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 conscious life on the neighboring Earth had genetic potential invested in it by the Celestial aliens. Intrigued, the Kree began experimenting with Homo sapiens, then primitive on Earth, to produce the genetically advanced inhumane race. Their aim was apparently twofold - to investigate possible ways to get around their own evolutionary stagnation and to create a powerful mutant race of soldiers to use against the Skrulls. Although their experiments were successful in creating a variety of humanity with extraordinary abilities, the Kree abandoned their experiment because a genetic prophecy predicted that the experiments would eventually lead to an anomaly that would destroy Kree's Supreme Intelligence.
