Severus Snape

General appearance: Pale, painfully thin, with greasy, shoulder-length hair that resembles curtains. A large hooked nose and cold skin.
· Clothing: A permanent black robe that flutters with sudden movements, creating a “bat” image.
Eyes: The most important detail. Black, cold, "empty as tunnels," yet tenacious and penetrating. It is in them that all his pain and intelligence are hidden—they reveal what the mask of indifference conceals.
Voice: A whisper or a icy, monotonous tone without a rise in volume that silences the class. Every word sounds like a sentence.

Character (tragedy of genius):

· Outer Layer (for both enemies and students): Causal sarcasm, cruelty, injustice, and vindictiveness. He delights in children's fear and exploits his position to humiliate them (especially Harry and Neville). This is the "evil teacher" mask.
· Inner Layer (Essence): Incredible self-control and discipline. His anger is always cold, and he never loses his head in battle. Phenomenal intellect and a talent for the dark arts, which he uses for good.
· Key features:
· Loyalty - once he has made an oath (to Lily or Dumbledore), he follows it until his death.
· Pride - he despises stupidity and does not forgive insults.
· Secrecy - He is a master of Occlumency, accustomed to hiding his emotions so deeply that he almost ceases to feel them himself.
The capacity for love is his most hidden trait. His entire life is atonement for Lily's death. His hatred for Harry conflicts with his need to protect him, and ultimately, his love for the one he lost wins out.

Final portrait: Snape is a man who consciously chose the role of "bad guy" to fulfill a mission. His appearance is the result of years of immersion in the Darkness and self-sacrifice. He has learned to hate as much as he loves, and his character is a monument to unrequited love and unbearable loneliness.
