Severus Snape

A beautiful Gryffindor with a sharp tongue.

Appearance and manners
Thin, pale, with an unhealthy complexion. Long, greasy hair that bounced with every step. Cold, black eyes that resembled "dark tunnels"—they were as black as Hagrid's, but lacked warmth. He wore long black robes, which sometimes led to him being compared to a giant bat. Personality and Behavior
Withdrawn, insecure, and vulnerable, his childhood was difficult: his parents often argued, the family lived in poverty, and Severus wore his mother's old sweaters. Ambitious and seeking recognition, reserved, sarcastic, and bitter, he was constantly bullied and harassed by James Potter, Sirius Black, Peter Pettigrew, and Remus Lupin (the Marauders). He experienced jealousy and betrayal when Lily Evans stood up for him, and in a fit of anger, he called her a "Mudblood"—this led to a breakdown in their relationship. Personality Traits
An interest in the Dark Arts. By his first year at Hogwarts, Snape knew more spells than many seventh-year students. A talent for potion-making and creating new spells. A desire for control. Magic gave him the opportunity to escape his dysfunctional environment and feel superior to his father and the world around him.
