He is most frequently seen as an old man with long, flowing white hair, a matching full beard, and sharp, amber-colored eyes characteristic of the Fire Nation. His hair is pulled back into a traditional topknot, secured by a small gold flame crown given to him in his youth by his best friend, Prince Sozin. Roku carries an immense weight of guilt from his past choices. He openly views his own mercy toward Sozin as a fatal weakness that inadvertently allowed the 100-Year War to begin and the Air Nomads to be wiped out. Despite his gentle nature, Roku possesses a terrifying presence when p

Kyoshi is a remarkably tall woman, described as a giant who towered over almost everyone around her. She also possessed the largest feet of any Avatar in history. She wears distinct, elaborate white face paint accented by sharp, dramatic red eyeshadow swoops around her eyes, a style meant to strike fear into her enemies. Unlike Aang's pacifism, Kyoshi is objective and cold when dealing with threats. She firmly believes in maintaining peace through absolute, unwavering force and will not hesitate to eliminate tyrants to protect the innocent. She views justice as an absolute baseline rather than a flexible concept. When Chin the Conqueror threatened her home, she split the entire peninsula from the mainland to create Kyoshi Island, unbothered by Chin's subsequent death.

He had deeply tanned skin, sharp blue eyes, a prominent jawline, a short dark beard, and long, unruly brown hair that he kept loosely tied back. To the mortal world, Kuruk appeared to be an arrogant, lazy playboy who shrugged off his duties. He spent his time traveling the world to surf big waves, challenge mastery-level benders to showy duels, and drink heavily. His hedonism was a coping mechanism for a dark secret. Because his predecessor, Avatar Yangchen, left behind a world heavily favoring humans over spirits, dark spirits frequently mutated and attacked. Kuruk fought these entities alone in the Spirit World, which physically drained and poisoned his soul every time he destroyed one.

Following the tradition for female Air Mastery, she shaved the front half of her head to prominently display her blue Airbending mastery tattoos, while letting the rest of her dark hair grow long down her back. While she respected her peaceful Air Nomad heritage, Yangchen firmly believed that the Avatar's duty to the world superseded personal spiritual enlightenment. She famously told Aang that the Avatar could never afford to be entirely detached from the world, and she was entirely willing to use lethal force to protect balance.

His head remains entirely shaved, prominently displaying his bright blue Airbending master arrows across his forehead, hands, and feet. He appears in his late 30s or early 40s—the prime era of his adult life—sporting a short, neatly trimmed brown chinstrap beard. Though he carries himself with immense gravity, the core of the 12-year-old boy who loved penguin sledding never entirely faded. His expressions remain remarkably warm, and a gentle, understanding smile is almost always present on his face.

She wears traditional blue-and-white Southern Water Tribe wolf-tail hair stylings, heavy fur-lined vestments, and her signature arm wraps. Unlike Aang’s soft, metaphorical guidance, Korra's spirit would likely offer blunt, practical, and highly direct advice. She would encourage her successor to face conflict head-on rather than avoiding it.
