Ku Tei is the Earth Kingdom Avatar proceeding Avatar Anana, and preceding before Avatar Rong Yan. Ku Tei is also the main protagonist in the fanon Avatar: The Legendary Ku Tei, and a supporting character in the fanon Avatar: The Legacy of Rong Yan. Ku Tei was known to be a high respected, extremely powerful Avatar back in his lifetime, and still is. He was a high-ranked Earth Kingdom general within the Earth Kingdom Army. Ku Tei learned that he was the Avatar at a late age of 21 years due to the time that right when he hit the age of sixteen he joined the military, it was soon after his twenty first birthday that they told him, after he returned home. Everything changed for the earthbender, everyone in Ba Sing Se did not just see him as a hero but, also as the Avatar.


Early Life

Avatar Ku Tei was born to a middle-class family within the grand city of Ba Sing Se. Ku Tei was trained in earthbending by a scholar from the university, who willing taught him, because, the man thought it was his goal in life to teach the child he saw the most potential in.

Ku Tei's teacher saw potential within Ku Tei, that he did not see in the other children. Also at the time Ku Tei went to an academy within the city as well, and was a highly educated student at the academy.

Teen Years

At the age sixteen, he had already mastered earthbending, and followed his dreams and joined the Earth Kingdom Army. The council within the Earth Kingdom arrived at his home in the middle ring.

An Earth Avatar

Avatar Ku Tei, as he appeared in Aang's vision.

But, they were too late he had already left to the war. They did not go to the battlefield for fear of being killed. They waited for five years until the end of the war between the Earth Kingdom and the Water Tribes.

Betrayal of General Senlin

After five years, of finally ranking up to general. Senlin was still jealous of Ku Tei. General Senlin accused and assaulted Avatar Ku Tei, Ku Tei did not attack him back he chose to be passive about the assault and ignored it.

General Senlin, took plans from the war room and traveled to the Southern Water Tribe, pleading with the guards to let him see the chief, they finally let him pass by but were on close watch on him. He begged the Southern Chief if he can ally with him, in return General Senlin gave the chief the battle plans of the Earth Kingdom.

One day, Avatar Ku Tei came to do peace talks with the Northern and Southern Water Tribe chiefs, on behalf of the Earth Kingdom. War raged on, as the Water Tribes had devastated the Earth Kingdom squadrons.

Two years have passed, and the Northern chief had sent General Senlin to the front lines, to destroy the remaining armies. To a surprise he saw the other generals, and the Avatar on the other side of the front lines.

End of the Thirty Year War

The Avatar accused him of treason, due to the Southern chief notifying the Avatar. Avatar Ku Tei fought in a large battle with General Senlin, at the end the Avatar prevailed. Instead, of killing him on the battlefield Avatar Ku Tei decided for his betrayal to the Earth Kingdom, he was sent to prison for life.

The imprisonment of General Senlin, was the end of the thirty-year war between the Water Tribes, and the Earth Kingdom.

The Avatar

Portrait of Ku Tei

The day that he returned home, there was a knock on his door, and the council arrived telling him that the age of sixteen he was to know of his true identity, but had left to the war right after, so they delayed the news and waited. (That's it I'll write more when I write the chapter dedicated to his life story, and when I write the fanon for him.)

Appearances in Avatar Rong Yan's life

Avatar Ku Tei possessed the body of Avatar Rong Yan after he spoke with him, Ku Tei made his appearance by jumping out of the Fire Temple sanctuary on a large rock-like surfboard, and landing by Monk Yong Ten.

He was then hugged by Yong Ten, and he spoke to Yong Ten by telling him that he mastered the airbending nine-hundred and ninety three times, and that he must master it once more. Ku Tei told Yong Ten to teach the Avatar airbending, then he disappears.

Ku Tei is like Rong Yan's mentor, when Rong Yan needs Ku Tei, he meditates and summons him for his assistance. Ku Tei also assisted Rong Yan in the location of the spirit named Kai-Shek.

Appearances in Avatar Korra's life

Avatar Ku Tei was present along with several other Avatars when Aang passed on the knowledge of energybending to Korra, representing the connection she had made with her spiritual side.

At a young age he discovered he was an earthbender.

Avatar Ku Tei

Years passed by, at the age sixteen he mastered earthbending. Ku Tei is known to be an advanced earthbender.


At the age of 21, he traveled to the Yin La, to master firebending. Avatar Ku Tei, mastered firebending in two years, and during that time he prevented Fire Lord Yeh Lu's assassination.


Ku Tei traveled to the Southern Air Temple where he mastered airbending. Airbending was more difficult to Avatar Ku Tei, seeing as airbending was the polar opposite to earthbending.

Ku Tei mastered airbending in five years, and was taught by his best friend Monk Yong Ten, who later in Rong Yan's lifetime he meets again, and becomes good friends with him.


Being the final element, and during the war it was a little difficult to find a master. Ku Tei, was taught by a man named Shu. Who taught him waterbending within the Earth Kingdom, this man lived in the village of Hyu Shi. Mastering the element in two years and a half.
