Azula

Azula is a princess of the Fire Nation, daughter of Fire Lord Ozai and Ursa, younger sister of Zuko and older half-sister of Kiyi.

After Zuko was banished from the Fire Nation, Azula assumed the role of direct heir to the throne and principal heir.

A prodigy in firebending, Azula is a manipulative and power-obsessed individual. She was a skilled strategist who orchestrated the coup in the Earth Kingdom capital, Ba Sing Se, and halted the invasion on the Day of the Black Sun.

Azula suffered from profound mental instability, believing that her mother loved Zuko more than her. Raised by her father in an environment devoid of a mother figure, Azula needed to be perfect in his eyes to gain his affection and attention.

Although Azula and Zuko had a decent relationship in their early years, the siblings drifted apart as they grew older due to their parents' behavior. While Azula was clearly Ozai's favorite, she felt her mother loved Zuko far more than her, creating a jealous rift between her and Ursa and Zuko. As a result of this resentment, as well as Ozai's influence, Azula became increasingly cruel and manipulative, frequently bullying Zuko and taking pleasure in his misery. She also manipulated her friends Mai and Ty Lee. Due to her growing tendency towards malice and a desire for perfection, Azula craved power to keep others close and avoid loneliness.

Her personality is marked by an unrelenting pursuit of perfection, emotional coldness, brilliant intelligence, and deep traits of narcissism and manipulation.
