This article is about the character. For other similar uses, see Sozin's Comet (disambiguation).

Sozin was the instigator of the Hundred Year War and the Fire Lord before his son, Azulon. He was grandfather to Iroh and Ozai and great-grandfather to Lu Ten, Zuko, and Azula.

As a young prince, Sozin was best friends with Avatar Roku. However, after Sozin took up the throne and Roku became a Fully Realized Avatar, their friendship became strained, as Sozin desired the Fire Nation to encompass the entire world, a plan to which Roku was strongly opposed. Following a confrontation over this which ended in Sozin's defeat, neither spoke to the other until they were seventy years old. Upon meeting the Avatar again, Sozin left his old friend to die, and began a war that would last one hundred years.

Using the fire-enhancing power of a comet, Sozin eradicated the Air Nomads in an attempt to preemptively eliminate the next Avatar, but failed. He spent the last years of his life hunting the new Avatar in vain.[1]


Early life

Roku and Sozin at age sixteen

In their early years, Roku and Sozin were close friends and celebrated their birthday together.

In his youth, Prince Sozin was best friends with Avatar Roku, and the two of them often celebrated their shared birthday together. As they were both firebenders, they regularly fought duels against one another for fun, and to test and strengthen their skills. Sozin also tried to get his best friend to confess his love for Ta Min, but Roku never found the courage to do so.[1]

At their sixteenth birthday celebration, Roku was unexpectedly told by the Fire Sages that he was the Avatar, and the two friends were forced to separate as Roku went to learn mastery of the three other elements. Before leaving, Sozin came by to talk and was told by Roku that the Sages told him to bring nothing, as the Avatar did not need material goods. By this statement, Sozin gave him a gift: the headpiece worn by the Crown Prince of the Fire Nation, hoping that he was at least allowed to have that.[1] Eight years later, Sozin would ascend to the throne; following the death of his father.[3]

Reign as Fire Lord (58 BG - 20 AG)


Twelve years after his departure, Roku returned to the Fire Nation. Even though many years had passed, Sozin still considered Roku his best friend, and warmly greeted him upon his return. The Fire Lord even willingly ignored old customs of respect for the Avatar and happily hugged Roku just like in their youth.

Adult Sozin and Roku

Seeing an opportunity for global expansion, Sozin explained his plans to Roku and invited him to help build an empire.

Sometime later, at Roku's wedding, the Fire Lord took the position of Roku's best man. However, Sozin also saw the wedding as his best opportunity to talk with his friend about his future plans. Subsequently, the Fire Lord approached Roku shortly after the wedding and took a walk with him. Sozin commented that the Fire Nation was going through a period of great prosperity and wealth and told Roku that together, the two of them could spread it throughout the world by expanding the empire, to make a "brighter future" possible. However, Roku was greatly disturbed by this, telling Sozin that the four nations were meant to be separate and that he should not think of this again. The Fire Lord asked his friend to at least consider the possibilities, but Roku remained stubborn.[1] Despite Roku's warnings, Sozin prepared for the unification of the nations through war. He greatly expanded the Fire Nation's already powerful army and navy,[4] and ordered the establishment of colonies in the Earth Kingdom.

Seventeen years later, however, Roku discovered the colonies and came to rebuke him. The Fire Lord was outraged that the Avatar, still a Fire Nation citizen, dared to treat him like that. Sozin warned his former friend that "[their] loyalty is to [their] nation first. Anything less [would make him] a traitor." Roku, however, replied that the Fire Lord should not challenge him, as it would "only end badly", leading Sozin to wrathfully attack him. The two engaged in a short battle, with Roku finally destroying most of the palace and defeating Sozin. Roku spared his life because of their past friendship, but warned him never to move forward with his plans again, or it would result in his "permanent end".[1]

Sozin refuses to help Roku

Sozin left Roku to die, knowing he could dominate the world without the Avatar's interference.

Twenty-five years later, Roku's home island was consumed in a volcanic eruption so massive that Sozin could see and feel it from a hundred miles away. The Fire Lord flew in on his dragon to assist his old friend. The two used their bending to try to contain the lava flow, but were hindered by poisonous gases, which eventually overwhelmed Roku, leaving him lying on the ground and begging for his old friend's help. Sozin suddenly realized, however, that Roku's death would allow him to fulfill his plans, and left his old friend to die along with his dragon, Fang.[1]


Twelve years after Roku died, Sozin used the power of a comet to enhance the abilities of his firebending army and launched a genocidal attack on the Air Nomads in an attempt to kill the new Avatar and break the Avatar Cycle.[5] However, Sozin failed, as Aang had run away from the air temples some time before.[6] Sozin spent the rest of his life searching in vain for the last airbender. After the comet, he lived twenty more years and had a son, Prince Azulon.[5]

Sozin and his army

Sozin assembled his forces to begin the Hundred Year War.

One of his lesser-known military accomplishments during this period was the Battle of Han Tui, which was applauded as a magnificent display of skill and military cunning.[7] He also fortified the Fire Nation Capital, designing a new road from the harbor to the Royal Caldera City. By creating a series of switchbacks in the narrow pathway, which forces any approaching party to travel in single column, and heavily fortifying it with watchtowers and battlements every hundred yards, he created one of the most secure roads in the world.[8] During his reign, Sozin started the tradition of hunting dragons for glory. If a firebender proved able to kill a dragon, the original firebenders, he would be showered with glory and praise, and earn the honorary title "Dragon". This led to the near-extinction of the dragons.[9]

As his reign carried on and the war escalated, Sozin established a vast cult of personality centered upon himself and the royal family, one that would be upheld through the reigns of Azulon and Ozai after him. Numerous monuments were constructed in reverence of himself, and the imperialist regime enforced various forms of propaganda that established Sozin as a higher, benevolent being. Such propaganda included the false claim that the Air Nomads possessed an army when in truth they were a pacifist culture.[10] Additionally, Sozin ordered that the Dragonbone Catacombs be sealed off so that all Fire Nation history recorded before his reign would be erased from the national conscience, making it appear as if Fire Nation history began with himself.[11] Furthermore, he outlawed same-sex relationships.[12]

He eventually died at the age of 102. Rumors circulated that he lived to be older due to the influence of the power of the comet.[5] According to what was learned in Fire Nation schools, Sozin died peacefully in his sleep, an old and successful man. However, according to his last testament, Sozin reminisced by the end of his life about how his younger years used to be "brighter". Like all Fire Lords, Sozin was buried in the Dragonbone Catacombs.[1]


Sozin outraged

Originally honest and kindhearted, the desire for power changed Sozin into a ruthless and cruel man.

Sozin was ruthless as Fire Lord, as demonstrated by his ordering the genocide of the Air Nomads simply to locate and destroy a single obstacle to his power, and his decision to start the tradition of hunting dragons despite having one as a companion. His betrayal of his closest friend, Avatar Roku, also highlights his willingness to embrace power over friendship and kindness. However, unlike his more militaristic son Azulon and grandson Ozai, Sozin, at least initially, saw his war with the other nations as a case of 'ends justifying means'- he hoped not simply to increase his own power, but to provide the other nations' with the Fire Nation's higher standard of living and perceived better system of order.[1] Domestically, Sozin preferred to silence, but not to completely destroy, opposition to his policies. This is exemplified in the fact that he did not execute Fire Sage Kaja, a known friend of Roku, when the latter declared that the new Avatar had not died during the Air Nomad Genocide.[13] Additionally, when Sozin wanted to eliminate the Fire Nation's ancient history to legitimize his policies, he chose not to destroy the historical corridors of the Dragonbone Catacombs but to simply seal them, believing he could still learn from the past.[11]

Sozin was close to his family, as he was genuinely worried about his father's well-being when the Fire Sages came to announce Roku to be the Avatar, and for at least the first few decades of his life, he treasured his friendship with Roku; despite his royal status, he consistently treated Roku as an equal until their friendship fell apart over his imperialistic ambitions. Despite their unpleasant split decades earlier, he went to help his former friend when he saw Roku's volcanic island erupt; though despite Roku saving him at one point, Sozin ultimately left him to die, realizing that without the Avatar, he was free to carry out his plans for the Fire Nation and the world.[1]



Heat redirection

Sozin was able to absorb and redirect the heat from the lava that consumed Roku's island.

Like many Fire Lords, Sozin was a powerful firebending master. When he was young, he sparred with Avatar Roku and defeated him on more than one occasion. When Roku confronted him years later about his actions in the Earth Kingdom, Sozin attacked him by unleashing a massive wave of fire against him, even though he did not have access to the power Sozin's Comet provided. However, he was still no match for Roku, who had all four elements and the Avatar State at his command. When he helped Roku tame an erupting volcano, he used a technique to redirect heat, cooling the lava.[1]

Other skills

Sozin was an intelligent strategist. When he and Roku were teenagers, Sozin tricked Roku into tripping over a tree root in order to win a sparring match. Sozin's intelligence made him a capable military leader. During the Hundred Year War, Sozin won the Battle of Han Tui by taking advantage of the fact that the enemy had been in the middle of a drought and downwind. According to Azula in a later recounting of the event, their defenses burned to a crisp in minutes.[7]

  • An early script of the premiere episode included a friendly duel between Avatar Roku and Sozin when they were younger, similar to the one shown in "The Avatar and the Fire Lord".[3]
  • People in the Avatar universe believe that the power granted from Sozin's Comet is what allowed Sozin to live as long as he did.[3]
  • Sozin was responsible for manipulating firebending's roots, changing it to match his militaristic and conquering goals,[9] as well as criminalizing same-sex relationships.[12]
  • Sozin is the only known firebender able to redirect heat.
  • Sozin began the tradition of hunting dragons, the original firebenders.[9]
