First appearance

Chapter 20: The Campaign of Two Nations Part 2: A Divided Nation

Gao Zu is one of the few oldest kings who ruled in Omashu in the history of the entire western Earth Kingdom. The Earth Kingdom has always been a divided nation since the beginning of the settlements in the area. Civil wars have happened but they have always kept the province divided rather than united. King Gao Zu, the arrogant old coot that he is, never knows when to stop talking. He is a minor character in Avatar: The Legacy of Rong Yan.


Gao Zu, was born to the royal family of Omashu in 781 BG being a crowned prince to the throne. His great grandfather held the throne for many years of Gao Zu's life until he died when Gao Zu was eleven. After that Gao Zu's father had ascended the throne in 770 BG. When Gao Zu had turn 38 years old his father retired from the throne and had given the title of king to his son Gao Zu.

In 743 BG, Gao Zu took the throne and the crown at 38 years old after his father had retired from being king for 27 years. Gao Zu when he was a boy was taller than the average child of his age growing to be four feet at the age of six and five feet at the age of nine. When Gao Zu became king he was roughly six foot five, he a muscular man because he liked the hobby of working out his body.

As a boy he didn't go to the public or private schools that Omashu provided he was taught by a royal tutor who taught him the history of the western Earth Kingdom, mathematics, literature arts, and religion. As he grew older the history changed to politics. Gao Zu at the age of seventeen had to know all the problems that were going on in the western Earth Kingdom and basically summaries of the other world leaders and the basics to their governments.

As he studied the various world politics, economies and the like his favorite hobby was exercising, working out his body with earthbending he grew boldly. His grand-uncle had trained him in earthbending, when Gao Zu was twenty he became a master of earthbending. With the skills and the body he had, Gao Zu had grown cocky, being the son of the current King of Omashu and the crowned prince of Omashu had made him grow into a braggart and later brought in his arrogance.

From the age of twenty through the age of 26, his cockiness brought trouble as far as to gangs targeting him for not paying them the money he owed and such. Although he would have been protected at all times there were times where he would sneak out of the palace. He always told himself that the life of royalty was never for him, he wanted a thrill-seeker's life full of fun.

It was later that his father had gotten to know Gao Zu's little fiasco and at one point had him arrested along with some friends who were petty criminals that Gao Zu would hang out with. Learning his lesson and spending half a year in prison did Gao Zu truly learn his destiny. Almost 27, he cleaned up his act and began to prepare himself to become King of Omashu, up to his father's high standards of a King.

Being the only child, his father and mother expected great things of Gao Zu and wanted him to be a smooth leader. But with his personality the first few years of his reign were a little rocky for the western Earth Kingdom. Behind the curtains his father the former king helping his son fix things both economically and politically so that the other world leaders would not see the King of Omashu as weak, that would've made him vulnerable to attacks from either of the other nations.

Thirty Year War

During the Thirty Year War, Gao Zu lent his aid to Ta Po, when the eastern Earth Kingdom had become a target of the Southern Water Tribe, who had aid from the Northern Water Tribe as part of their ancient treaty. The war had begun on raids from the Water Tribes to coastal towns of the eastern Earth Kingdom. It is unknown the main reason why the Water Tribes had attacked the coast of the eastern Earth Kingdom, but that had sparked the war. Where the Earth Kingdom nations had retaliated in return.

It was fifteen years later into the war that Gao Zu had pulled out his large military from the battle of Gunglao Forest. Leaving the Ba Sing Se military alone, two hundred men died in the battle of Gunglao, if Gao Zu hadn't pulled his men out it would've been a decisive victory for the Earth Kingdom. It is also unknown as to why Gao Zu had pulled out from the war, but if you were to ask you would be ignored.

Avatar Ku Tei, had threatened Gao Zu for the completely coward decision he had made at Gunglao. The two fought in a battle in Gao Zu's arena but the duel ended in a stalemate, Gao Zu never told anyone why and to this day it is still unknown. Captain Senlin and a few others were later found in Chao recovering from their wounds in Gunglao. General Senlin and four others were the sole survivors of Gunglao while the rest of the forest was covered with rotting bodies from both sides.

War Council

During the first few days of the new war that had begun, Earth King Qiang Zhen had invited Gao Zu to stay in Ba Sing Se for a few days and discuss the meeting he had invited him to. The meeting had later turned into a war council, it was during the war council that Gao Zu was presented evidence as to what had begun the war. After making plans for first movements, Gao Zu had changed his mind and had declined Ba Sing Se the aid in the new war.

Commenting that this was Qiang Zhen's war not his, and he will have no part in his affairs. That's when General Ren had mentioned the Thirty Year War and saying that the claims of the once great legendary King of Omashu was nothing but a myth. Saying that Gao Zu was too afraid to fail and that he was an arrogant coward. Gao Zu had snapped and had assaulted Ren, in return the fight was stopped by General Tsyuo-sa the result was Gao Zu and Naoren De were kicked out of the war room. Storming back to the Ba Sing Se palace they gathered their things and left Ba Sing Se.

Long Live the King of Omashu

No check Not done


Gao Zu was born an earthbender, it was at the age of seven that his gran-uncle had trained him in earthbending. Through all the long years of bloodshed, tears, and discipline did Gao Zu eventually master earthbending at the age of twenty.


Thanks to the royal tutor within the palace, Gao Zu had learnt a great amount of world politics and economy tricks and tips. Although it really didn't help him in the beginning since his first few years of his reign everything was pretty difficult for him to maintain. His retired father was the actual king behind the curtains as Gao Zu ruled as a puppet until he was 41.
