Severus Snape

Snape is tall and thin, with black hair and a hooked nose. He is a teacher in potions at Hogwarts. He also is the head of slytherin house, but he does not like being a teacher, and he despises his students. Despite his forbidding appearance, he is an intensely intelligent and talented wizard with a passion for the Dark Arts, a gift for potion-making, and an ability to teach that no one can match - when he can be bothered. He is also a very complex character who can be cruel, vindictive, and self-righteous, but who can also be brave, selfless, and deeply loyal. He can also be sarcastic and bitter. Snape is also a double agent for Dumbledore. He spies at the deatheaters for Dumbledore, pretending to be a deatheater himself. He can also be sarcastic, bitter and he is extremely cold. He also is quite silent, but can abruptly become angry.
