The Predator (プレデター) is a ferocious creature that was a fusion-evolution result of combining infected lab predators and lab primates. The Predator is the only creature that can be active outdoors as well as in, thanks to its molecular structure which can crystallise, forming an exoskeleton, in open air conditions. Conversely, the Predator cannot inhabit warm areas. It can also alter the refractive index of its body surface crystals, allowing it to become invisible.
