Fang

Fang was Avatar Roku's friendly dragon, animal guide and loyal steed; Fang was at Roku's side from his birth until his death. He was Roku's animal companion, much like Appa was to Aang and Naga is to Korra.

History
Roku found Fang when he was just a baby, not yet hatched from his egg. Fang's parents were gone, so Roku raised the young dragon as his own and they became inseparable.

When Roku's island experienced a massive eruption in 12 BSC, Fang attempted to aid his friend. Even though Roku insisted that he leave, Fang stayed with him the entire time. After initially helping Roku to contain the eruption, Fire Lord Sozin betrayed Roku and left him to die. Fang then curled up around Roku to protect him and the two died together when they were overrun by a pyroclastic flow. Fang then entered the Spirit World along with Avatar Roku.



Fang first appeared to Aang when he was attempting to stop Hei Bai from destroying Senlin Village. After Aang discovered he was in his spirit form for the very first time, he was confronted by Fang. Fang took Aang to the Fire Temple on Crescent Island to see Avatar Roku's statue. Aang found out that Avatar Roku wanted to speak to him about Sozin's Comet, and the only time they could talk was during the winter solstice. The dragon then took Aang back to his body. Fang was not seen again until Roku talked to Aang about the dangers of the Avatar State. He was later shown flying Roku and Aang to the Southern Air Temple in Roku's memories, and then in his living form during flashbacks.

Spiritual abilities


As a spirit, Fang wielded several abilities common to all those who resided in the Spirit World, such as intangibility, passing through solid objects, and invisibility. Due to being a dragon, he retained his ability to fly. However, what really made Fang unique was that he had telepathic abilities, which were used for communication with others as well as information transmission, and were sent by using its whiskers. He could not actually transmit speech, but instead sent images and impressions. When Aang first saw Fang, the latter used his ability to tell Aang that he was Roku's dragon. When they reached the Fire Temple, he used it again to let Aang know when and where he can talk to Roku. Afterwards, he sent Aang back to the real world by flying into Hei Bai's statue, which reawakened Aang's lifeless, meditating shell. The only people known to see him in his spiritual form in the mortal world were Avatar Aang and General Iroh.
