 The Nemesis, named after the Goddess of Vengeance from Greek mythology, first appears in the 1999 PlayStation game Resident Evil 3: Nemesis as the game's title character and primary antagonist. The product of years of research, the prototype is deployed by the Umbrella Corporation to hunt and kill the STARS police team as a field test, and as revenge for the destruction of the original Tyrant. The game ’ s protagonist, Jill Valentine, first encounters the Nemesis outside Raccoon City ’ s police station where it kills Brad Vickers and then pursues her, uttering "STARS ..." on sight. The Nemesis continues to stalk Valentine throughout the game, attacking with physical blows and grabs, and later, armed with a rocket launcher. After losing its overcoat as a result of heavy damage, the Nemesis mutates, and gains the ability to attack with long, extendable tentacles. Despite later being doused in acid, the Nemesis continues its pursuit, and mutates into a much larger monster after absorbing a dead Tyrant, gaining the ability to spew poison. Jill finally defeats the Nemesis using a rail cannon, and then depending on the choice of the player, she either kills it once and for all by unloading her weapons into it, or leaves it to die in the nuclear explosion that destroys Raccoon City.
