 In the series'story, the Nemesis is the result of infecting a Tyrant — a humanoid bio-weapon created to be the ultimate lifeform — with a parasitic organism designed to increase its intelligence. Upon infection, the parasite takes control of the Tyrant's nervous system, forming its own brain and enabling it to follow precise instructions and make decisions without a need for constant direction. Clothed in black trousers, an overcoat, boots, and gloves, the Nemesis is armed with a rocket launcher mounted on its left arm. To emphasize its design as a prototype, the game developers left exposed muscles on its body and added stitches to cover the right eye. Upon spotting its target, it says the target's name out loud and attacks.
