Severus Snape


Severus Snape is a fictional character in the Harry Potter book series written by J.K. Rowling. In the first novel, Harry Potter and the Philosopher's Stone (published as Harry Potter and the Sorcerer's Stone in the United States), he is built up to be the primary villain until the final chapters. As the series progresses, Snape's character becomes more layered and complex, and Rowling does not fully reveal the details of his true loyalties until the end of the final book, Harry Potter and the Deathly Hallows. Snape appears in all seven novels of the series.

Over the course of the series, Snape's portrayal evolves from that of a malicious and partisan teacher, to that of a pivotal character of considerable complexity and moral ambiguity. Snape teaches Potions at Hogwarts, and later becomes the Defence Against the Dark Arts teacher in the sixth novel, and becomes the Headmaster of Hogwarts in the final novel.
