Professor Severus Snape (January 9, 1960 – May 2, 1998), also known as the Half-Blood Prince, is a major character in the Harry Potter franchise.
Snape appears as a thin man with sallow skin, long greasy black hair, a hooked nose and black eyes. He also dresses in a flowing black robe.
Snape was normally a very calm and reserved person, but he possessed a brutal temper that would infrequently get the better of him. He would react violently if he thought he was being pitied.
