Not tall, but compared to player. Generally unsafe to approach unless his brother nearby. Horror sans weapon is heavy thigh bone, he pulls from ground. Red eye narrows when feeling emotion. Loves puns, papyrus, and psychological torture, extremely bored after so many years in underground; will not harm player (at distance) as long as he's entertained, head injury left him mild retrograde amnesia and unpredictable mood swings. Some events from Frisk's play though are lost in his memory.
