Koh, a centipede-like creature dwelling in the Spirit World, is infamous for his ability to steal faces. Encountering various incarnations of the Avatar over time, he particularly bears animosity towards Avatar Kuruk and Roku.His vendetta against Avatar Roku stems from the theft of a precious pendant belonging to his mother, the Mother of Faces.
The Mother of Faces possessed the unique ability to grant individuals their identities through different faces. Unfortunately, her son, Koh, acquired the dark power to steal faces, using them for sustenance and intimidation. In the animated series, Koh's victims fall prey to him when they display emotions in his presence. However, in the live-action adaptation, Koh's malevolence extends to kidnapping Katara and Sokka, placing them in a perilous slumber before devouring their faces.
Aang, the Avatar, is the only one permitted to exhibit emotions in Koh's presence. In a desperate bid to save his friends, Aang must confront Koh and return the stolen pendant to appease the vengeful spirit.
The tale of Koh reveals the intricate dynamics of the Spirit World and the consequences of crossing its denizens. As Aang navigates his journey to master all four elements, his encounter with Koh serves as a chilling reminder of the perils that await him in his quest to restore balance to the world.

In the enigmatic realm of spirits and avatars, Koh's story stands as a testament to the intricate mythology woven into the narrative of Avatar: The Last Airbender. As viewers immerse themselves in the saga of Aang and his companions, they are drawn into a world where the line between darkness and light blurs, and the true nature of heroism is tested.
