Character from Harry Potter by J.K. Rowling
Voldemort's enormous snake familiar and final Horcrux, sharing a psychic bond with her master and serving as both weapon and vessel for a fragment of his soul.
Nagini is more than a pet — she is an extension of Voldemort's will, carrying a piece of his soul and sharing a telepathic connection he can see through. She kills on command with venom or constriction and guards her master with predatory vigilance. Voldemort trusts her more than any human follower, which says everything about his capacity for connection. She is the last Horcrux to be destroyed, and her death makes Voldemort mortal.
Enormous green snake, twelve feet long, thick as a man's thigh. Glittering dark eyes with vertical pupils. Moves with terrifying speed and silence.
Also known as: Nagini, the snake
