The Nemesis is characterized by its relentlessness, strength, sheer stamina, and comparatively high intellect. Unlike the various Tyrant models before it, the Nemesis shows it is capable of employing weaponry and firearms to achieve its objectives. It demonstrates rational thinking abilities, shooting down a rescue helicopter in order to trap Jill Valentine. It can even be heard speaking at times (though its only utterance is "S.T.A.R.S."). Unlike the other Tyrant models, the Nemesis had no mutated claws to attack its targets, relying instead on its sheer power, rocket launcher, and tentacles.
