who was the avatar before aang

This is the best avatar fan-fic ever with cool and strong chaotic anti avatar in. Story is good for now but after aang this story development is going to be bad and hard.

WATER💦, EARTH⛰️, FIRE🔥, AIR🌫️ Long ago, the four nations lived together in Harmony but then everything changed when the fire Nation attacked. Only the avatar, master of all four elements could stop them. But when the world needed him the most, HE VANISHED. A hundred of years has passed when my brother and I discovered the new avatar, an AIRBENDER named AANG. Although his airbending skills were great, he still has a lot to learn before he can save anyone. But I believe, AANG CAN SAVE THE WORLD.

I'll keep it short, very great novel = = = The world is divided into four nations -- the Water Tribe, the Earth Kingdom, the Fire Nation and and the Air Nomads -- each represented by a natural element for which the nation is named. Benders have the ability to control and manipulate the element from their nation. Only the Avatar is the master of all four elements. The ruthless Fire Nation wants to conquer the world but the only bender who has enough power, the Avatar, has disappeared ... until now. His tribe soon discovers that Aang is the long-lost Avatar. Now Katara and Sokka must safeguard Aang on his journey to master all four elements and save the world from the Fire Nation.

Katara (a fourteen-year-old Southern Tribe Waterbender) and her older brother, Sokka, find and revive Aang and Appa. Aang learns about the war, and the siblings join him to reach the Northern Water Tribe at the North Pole so he and Katara can learn Waterbending. Aang's return attracts the attention of Prince Zuko, the exiled son of Ozai, who pursues them. Aang is also pursued by Zhao, a Fire Nation admiral who intends to win Ozai's favor and rob Zuko of his redemption. En route to the North Pole, Aang meets the Kyoshi Warriors; his childhood friend, King Bumi, tries to learn Firebending from deserter Firebending master Jeong Jeong, and finds a winged lemur he names Momo. Aang learns about the genocide when he visits the Southern Air Temple. During the winter solstice he meets the spirit of his predecessor, Avatar Roku. With the Northern Water Tribe, Aang and Katara learn advanced Waterbending from Master Pakku; Sokka falls in love with the chief's daughter, Princess Yue. Zhao lays siege to the tribe, seizing the mortal forms of the ocean and moon spirits (the source of waterbending) and causing a lunar eclipse. Zhao kills the moon spirit, ****** the Waterbenders powerless. Aang uses his avatar state, joining the ocean spirit to drive off the enemy fleet while Yue sacrifices her life to revive the moon spirit. When Ozai hears about his older brother Iroh's resistance to Zhao, he sends his daughter Azula to capture Iroh and Zuko. After leaving the Northern Water Tribe, Katara continues teaching Aang waterbending while the group searches for an earthbending teacher. They meet Toph Beifong, a twelve-year-old, blind tomboy and earthbending prodigy who wants independence from her upper-class family. Pursued by Azula, Zuko and Iroh lead new lives in the Earth Kingdom as wanderers and refugees in the capital of Ba Sing Se. At a library guarded by the spirit Wan Shi Tong, Aang and his group learn that an imminent solar eclipse could let them stop the Fire Nation before Sozin's Comet arrives. During their journey to Ba Sing Se to inform the Earth King, Appa is kidnapped. In the city, they find it and the Earth King (Kuei) manipulated by Long Feng (leader of the Dai Li secret police). After Aang's group finds Appa and exposes Long Feng, Toph is captured. She escapes by metalbending; Aang tries to access the avatar state, as Azula nearly kills him. The Dai Li join Azula to instigate a coup d'état of Ba Sing Se, and Zuko (trying to ignore his past obsession) relapses when the Avatar appears to rescue Katara. With Ba Sing Se and the Earth Kingdom now under Fire Nation rule, the group escapes thanks to Iroh (who is imprisoned for betraying the Fire Nation); Kuei goes into hiding. Aang emergess from a coma to find his friends and allies disguised as soldiers on a Fire Nation ship, preparing to invade the Fire Nation. Zuko regrets his role in the Avatar's apparent death. Although the invasion is successful at first, Aang and his friends cannot find Ozai and are forced to retreat. Learning about his father's intention to destroy the Earth Kingdom during Sozin's Comet, Zuko leaves the palace to teach Aang firebending. Aang is reluctant to kill Ozai as the comet approaches, and consults his predecessors' spirits. Katara and the others unsuccessfully search for him. They find the escaped Iroh with the other members of a secret society, the Order of the White Lotus: Bumi, Master Pakku, Jeong-Jeong and master swordsman Piandao, who taught Sokka. The order liberates Ba Sing Se. Sokka, Toph and Kyoshi warrior Suki hinder the Fire Nation's airships, while Zuko and Katara prevent Azula from becoming the new Fire Lord. As the comet arrives, Aang confronts Ozai but is in a losing battle until Ozai mistakenly re-establishes Aang's connection to the avatar state. Aang strips Ozai of his firebending powers. Zuko is crowned the new Fire Lord, and arranges an armistice. The series ends with a meeting of the Ba Sing Se protagonists in the Jasmine Dragon, Iroh's tea shop, where Aang and Katara hug and kiss beneath the sunset.
