Overview
Severus Snape is a prominent character in J.K. Rowling's Harry Potter franchise. Serving as the Potions Master and Head of Slytherin House at Hogwarts School of Witchcraft and Wizardry, he later becomes the Defense Against the Dark Arts professor and eventually the school's Headmaster. A former Death Eater loyal to Lord Voldemort, he operates as a secret double agent under Albus Dumbledore's guidance, playing a critical role in the main story while using the alias 'the Half-Blood Prince'.
Appearance
Severus Snape has sallow skin, a prominent hooked nose, thin lips, black eyes, and uneven, yellowed teeth. He has shoulder-length, greasy black hair and typically wears heavy black robes, which lead others to compare his appearance to a giant bat. He speaks in a quiet, soft, silky voice.
Personality
Snape possesses a cold, gloomy, and highly strict demeanor. He exhibits clear favoritism toward his own House, Slytherin, while showing extreme harshness and unfairness toward students of other houses, particularly Gryffindor. Harboring deep-seated resentment toward James Potter and Sirius Black due to past hostility during his school years, he projects intense dislike onto Harry Potter. Despite his unpleasant outer personality, he possesses a strong sense of obligation and an extraordinary capacity for lifelong devotion to the person he loves.
Abilities
Snape is exceptionally skilled in the Dark Arts, Potions, Occlumency, and Legilimency, able to completely deceive Lord Voldemort's mind-reading capabilities. During his Hogwarts years, he invented original spells like Sectumsempra and Levicorpus while improving standard potion-making procedures. He is capable of performing non-verbal spells and flying freely through the air without the aid of a broomstick. His Patronus takes the form of a silver doe.
Background
Born to a Muggle father and a pure-blood witch mother, Snape grew up in a troubled home at Spinner's End. During his childhood, he befriended Lily Evans. Upon entering Hogwarts, he was sorted into Slytherin House, where his growing obsession with the Dark Arts and an unforgivable slur severed his friendship with Lily. After graduating, he joined the Death Eaters, but defected to Albus Dumbledore when Lily became a target of Voldemort. Following her death, he dedicated the rest of his life to protecting her son, Harry, while acting as a undercover double agent.
Relationships
Lily Evans was Snape's childhood best friend and sole lifelong love; his devotion to her shapes his ultimate allegiance. He holds deep hostility toward James Potter and Sirius Black due to their schoolyard rivalry, extending his bitterness to James's son, Harry Potter, whom he nevertheless protects to honor Lily. He brews Wolfsbane Potion to manage Remus Lupin's condition despite their tense relationship. Snape shares a complex bond of trust and absolute obedience with Albus Dumbledore.
Trivia
The surname 'Snape' was inspired by a village in North Yorkshire, while 'Severus' derives from the Latin word for severe. In his youth, he adopted the title 'Half-Blood Prince', combining his Muggle heritage with his mother's maiden name, Prince. In the film adaptations, he was famously portrayed by Alan Rickman. Following his death, he was posthumously awarded the Order of Merlin, First Class, and Harry Potter named his second son, Albus Severus, in his honor.
