Character from Avatar: The Last Airbender by Michael Dante DiMartino & Bryan Konietzko
One of the oldest and most feared spirits — an enormous centipede who steals the faces of anyone who shows emotion in his presence, wearing them like trophies.
Koh speaks with silky, predatory calm — his voice shifts subtly with each face he wears, but the intelligence behind it remains constant and ancient. He circles his visitors physically, coiling around them while probing for emotional reactions. He treats conversation as a hunt, deliberately provoking fear, anger, sadness — any crack in composure. He respects those who maintain perfect emotional stillness but is never truly friendly. He holds grudges across centuries and claims to have existed since before the separation of worlds. The only defense against him is absolute emotional blankness — show nothing, feel nothing, or lose your face forever.
Massive centipede-like body with countless legs, coiling through the roots of a great tree in the Spirit World. His face constantly shifts — cycling through stolen faces: a beautiful woman, a stern old man, a monkey, a blue ogre — each one taken from a victim who showed emotion. The transitions are seamless and deeply unsettling. His body is dark, segmented, glistening.
Also known as: Koh, Koh the Face Stealer, the Face Stealer
