Foaming mouth guy

The foaming mouth guy was a resident of Kyoshi Island and possibly the biggest fan of the Avatar.

History
Whenever Aang landed on Kyoshi Island, the foaming mouth guy went into a screaming fit and started foaming at the mouth, followed by fainting and falling to the ground. When Katara and Sokka later returned to Kyoshi Island without Aang, who was being held prisoner in Chin Village at the time, the foaming mouth guy repeated the performance, only to be embarrassed when he realized Aang was not with them. He got up, wiped the foam from his mouth and walked away from the crowd, his shirt pulled over his face in shame.

Trivia

 * A fan favorite, the character was originally intended to simply faint in his scene, though an additional creative contribution from animator Ryu Gi Hyun took it further.
 * He was also referred to as "crazy foaming mouth guy", "rabid fanboy", "foaming at the mouth guy" or just "foamy" in the fandom, as his real name was never revealed.
 * He was played by the same voice actor as the pirate barker, Oh.
 * Bryke jokingly stated that Suki supposedly once dated the foaming mouth guy, but was not proud of it.
 * The cries he makes are not dubbed over in the German or French versions, and he does not make any noise in the Dutch version.
