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 and falling 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, or perhaps an involuntary action that comes with being in the Avatar's presence. 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 seems to be an outcast.

Trivia

 * 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.
 * He is also referred to as "Crazy Foaming Mouth Guy", "Rabid Fanboy", "Frothers", "Foaming at the Mouth Guy" or just "Foamy" in the fandom, as we never hear his name.
 * In "The Runaway", a reference to Foaming Mouth Guy was made, when Sokka and Aang both frothed due to disbelief at Katara's desire to pull off a scam.
 * It is possible that he has Rabies, although this is unlikely due to the fact that the disease is fatal.
