Inhumans

At the beginning of the Kree-Skrull War, millions of years ago, the alien Kree established a station on the planet Uranus. They discovered that sentient life on nearby Earth had genetic potential invested in it by the alien Celestials. The Kree began to experiment on Earth’s then-primitive Homo sapiens to produce the genetically advanced Inhuman race. Although their experiments were successful in creating a strain of humanity with extraordinary abilities, the Kree abandoned their experiment. The Inhumans went on to form a society of their own, which thrived in seclusion from the rest of humanity and developed advanced technology.
