Wisdom-San

The Sumos' yogi-like teacher, who raised them from infancy and taught them the ways of P.H.A.T. He is usually seen in flashbacks, but sometimes appears in contemporary sections of the episode. He resembles an Eastern mystic, seems to wear nothing apart from sandals (although this is debatable, as his beard covers most of his body) and is often seen meditating, levitating, or both. He found raising the Sumos incredibly frustrating due to their greed and clumsiness.
