Master Mutaito

Master Mutaito, is one of the greatest Martial Arts teachers of all time, and the first known person to act as Earth's savior. He is Master Roshi and Master Shen's teacher and the one who taught them the most amazing skills of the martial arts. Mutaito was a disciplined and honorable warrior who cared deeply about his apprentices. He tried to avenge them once King Piccolo and his demon spawn killed most of them. He hated the Demon King Piccolo for what he did to his apprentices and the world and resolved to defeat him. However, he failed and was ashamed that he lost in front of his apprentices while also failing to avenge those who lost their lives. It was this failure that made him flee but also made him train more in hopes of finding a way to defeat King Piccolo. Eventually he managed to defeat the Demon King Piccolo using the Evil Containment Wave. Although it cost him his life, he died with a smile on his face as he regained his honor, avenged his apprentices, and rid the world of a terrible evil. When Goku time traveled, Mutaito showed he was strict with his apprentices, as he made Shen restart his training from the beginning once he saw he was causing harm to Goku and his friends. These traits earned the respect of Roshi who continues to think highly of his master and used his teachings to train the Z-Fighters, who would later also try to protect the Earth from the forces of evil. As he and his pupils Roshi and Shen were no match for King Piccolo, Mutaito created the Evil Containment Wave. Mutaito and his two pupils confronted King Piccolo and Mutaito managed to seal the demon into an Electric Rice Cooker, though he died upon doing so.
