Mutaito is the teacher of Roshi and the Crane Hermit. Many years before the series, he and his students face Piccolo Daimao in battle. Many of his students are slaughtered and he is greatly injured, so he soon develops a technique to seal Piccolo away instead of facing him in combat. He then uses the new Evil Containment Wave to seal Piccolo at the cost of his own life. He appears in the anime after Goku uses a time traveling room to visit the time period. He will be played by Ernie Hudson in the upcoming film Dragonball.
