A perfect assassin, a species that was bio-engineered, turned out to be both uncontrollable and unstoppable. This being, with its remarkable intelligence and physical prowess, could imitate voices and camouflage itself within its surroundings, much like a chameleon. Following the killing of the scientific team responsible for its creation, it entered a state of suspended animation, awaiting fresh victims. Eventually, expedition IL5, exploring the remnants of the bio-engineering facility where the creature was made, inadvertently released it. Once awakened, the creature initiated a hunt, systematically eliminating the research team.
