Kyoshi

Kyoshi was the Earth Kingdom-born Avatar immediately succeeding Avatar Kuruk of the Northern Water Tribe, and preceding Avatar Roku of the Fire Nation. She died at the age of 230, making her the oldest confirmed human, and was also an exceptionally tall woman, towering over most people. Kyoshi was born to two criminals: Jesa, a renegade Air Nomad nun, and Hark, a thief from an impoverished family of Earth Kingdom actors. She inherited her later signature outfit from her parents, adopting her mother's golden headdress and metal war fans and her father's face paint. Later in her life she defeated an attempted armed takeover of the Earth Kingdom by Chin the Conqueror and founded Kyoshi Island and the Kyoshi Warriors to keep her adopted homeland safe. Kyoshi thus had few qualms about using her powers and enforce her will, openly threatening powerful people. In general, Kyoshi gave her most threatening opponents one chance to change their course and if they wasted it, she did not hesitate to end them. Despite that hard stance, she generally preferred to not kill anyone and was known to be more forgiving toward less dangerous foes. Kyoshi usually hid her self-doubts and compassion behind an image of righteous fierceness to fulfill her duties as the Avatar, showing her loving and friendly side only to those with whom she was close.
