Who is Koh?
Koh is known as the face stealer in the Spirit World. A centipede-like creature, he has been in the Spirit World for a long time and has encountered the Avatar throughout different incarnates. He particularly has a grudge against Avatar Kuruk and Roku. Avatar Roku stole a figure pendant of Koh’s mother, the Mother of Faces, from Koh himself.
The Mother Of Faces gave people their identity and had the power to give people different faces. Meanwhile, her son gained the capability of stealing faces, which he uses for food and intimidating victims.
In the animated series, Koh steals people’s faces if they show emotion towards him, leading Aang to be emotionless throughout the whole interaction. However, in the live-action adaptation, Aang is the only person allowed to show emotion to Koh. Koh kidnaps Katara and Sokka who are put in a deep slumber before they are eaten and have their faces stolen. Aang must return the pendant to Koh for his friends’ safety.
