Lu Ten

"fire"

- Happy birthday, my son. If only I could have helped you.

Prince Lu Ten was the son of General Iroh, grandson of Fire Lord Azulon, and great-grandson to Fire Lord Sozin. He was the nephew of Fire Lord Ozai and Princess Ursa, and cousin to Zuko and Azula. He was killed in combat during his father's famous 600-day Siege of Ba Sing Se.

Lu Ten's death had a traumatic impact upon his father, causing him to abandon the siege and ultimately provided an opportunity for Ozai to usurp the position of Fire Lord from his brother.

History
A prince of the Fire Nation and soldier in its war against the Earth Kingdom, and only son of General Iroh, Lu Ten died in combat against the Earth Kingdom several years before the start of the series during the Siege of Ba Sing Se. When he learned of his son's death, Iroh was so heartbroken that he abandoned the siege of the city, claiming that he and his men were tired from the extensive time away from home. Within the Fire Nation, after his uncle Prince Ozai learned of Lu Ten's death and Iroh's subsequent actions, Ozai petitioned their father Fire Lord Azulon to crown him heir to the throne, claiming that Lu Ten's death meant that the royal bloodline would end with Iroh, since he had no further heirs. Azulon was enraged at such a request, but because of his death soon after, Ozai took the throne. Iroh himself did not challenge Ozai's claim, even though he was the elder brother, and did not attempt to secure the throne for himself.

As revealed in flashbacks during "Bitter Work", Lu Ten and Iroh had a strong relationship during Lu Ten's childhood, and they remained close during his adulthood. His death had a profound effect upon Iroh, whose personality shifted more towards a calm acceptance of life, rather than continuing to participate in the current war. Judging by Zuko's stunned expression when he found out about Lu Ten's death, they may have been close, although their age difference may have resulted in more of a hero worship on Zuko's part.

Had Lu Ten lived through the war and Iroh taken his rightful place as Fire Lord, Lu Ten would have been next in line for the throne.

His exact cause of death in the battle is unknown.

Trivia

 * The picture on the altar that his father Iroh set up in "The Tales of Ba Sing Se" has his name as 路騰 (Lù T'éng) which translates as "road to gallop over".
 * Lu Ten was first mentioned in the Siege of the North when Iroh informs Zuko that after Lu Ten's death, Iroh began treating Zuko like his own son. A younger Lu Ten was then seen in "Bitter Work" and a picture of an older Lu Ten was displayed at Iroh's altar for him during "The Tales of Ba Sing Se".
 * When seen in the flashback in "Bitter Work", Lu Ten is voiced by Mae Whitman, who voices Katara.
 * Lu Ten's mother is unmentioned.
 * All the known Fire Lords, Sozin, Azulon, Ozai and Zuko, have the letters "O" and "Z" in their name. If Lu Ten had survived the Siege of Ba Sing Se and became a Fire Lord after Iroh, he would be the first in three generations not to bear either of the letters in his name.
 * "Tales of Ba Sing Se" with "Avatar Extras" bonus commentary misspell Lu Ten's name, spelling it as Lu Tin.
 * As he was the son of the Crown Prince (Ozai wasn't named as successor until after Lu Ten died) and heir to the throne after Iroh, it can be assumed that he was a powerful Firebender.
 * The words in top left of Lu Ten's portrait could be roughly translated as: "To General Iroh: See you after we win the war. Your loyal son Lu Ten."
 * It is thought by some that one of the faces Koh stole was Lu Ten's.
