Yōfu

Yofu [萬月; ようふ] is a semi-mythical figure of north Kanton legend, thought to be based on a warrior under the first Emperor Usan. It is said that he accomplished many amazing and borderline supernatural feats, including but not limited to:
* swimming the East China Sea in a raft made from oak leaves
* climbing Mount Taba with only the clothes on his back
* eating lit coals and breathing fire
* building a castle which could walk of its own accord
* hunting six hundred deer in just one day
* freezing water into ice with his own cold breath
In addition, Yōfu was said to have psychic abilities, along with supreme intelligence and strength which made him almost invincible in battle. According to folktale, Yōfu's final accomplishment was discovering eternal life. He became an ageless spirit, and disappeared into the Ikumo Mountains, never to be seen again by any mortal being.
