Foaming mouth guy



Foaming Mouth Guy is a resident of Kyoshi Island. His real name has not been revealed. Whenever Aang lands on the island, Foaming Mouth Guy goes into a screaming fit and starts foaming at the mouth, punctuated by fainting to the ground. When Katara and Sokka return to Kyoshi Island while Aang is being held prisoner on the mainlands, Foaming Mouth Guy repeats the crazy performance--only to get up from the ground once he hears Aang is not with them, implying that the entire sequence is an act. He wipes the foam from his mouth and walks away with his jacket pulled over his head in embarrassment.

Foaming Mouth Guy has never been known to speak actual words, only crazed gibberish. Judging from the confused/embarrassed reactions from other Kyoshi Island residents, Foaming Mouth Guy is somewhat of an oddball and outcast.

Trivia
Now a fan favorite, originally, the character was designated to simply faint in his scene, but an additional creative contribution from an animator named Ryu Gi Hyun took it further.
