Lao Tzu, Ruler of the Lao Dynasty, was a character on Xena: Warrior Princess. He was the husband of Lao Ma, who ruled in his place, due to his tyrant ways. She did, however, allow him to take the credit for all of her good deeds, including her infamous book of wisdom. She kept him in a coma using pressure points, and let him be seen in the garden once a month, to dispurse thoughts of him having died. Considering that Ming T'ien began to reign as the supreme ruler of Chin, the Lao line was presumably wiped out, meaning that he must of died some time shortly before or after Lao Ma's death.
