Sun Wukong's brother Raditz came to Earth and revealed Sun Wukong's original identity as a Saiyan, a fighting race. Sun Wukong and Piccolo joined forces to fight, but due to the gap in combat power between the two sides, they fell into a bitter battle. Sun Wuhan, the son of Sun Wukong, exploded with powerful fighting power at a critical moment and severely injured Raditz. Goku finally decided to die together, and held Raditz from behind the moment he showed his flaw, allowing Piccolo to use his special move "Magic Penetrating Light Cannon" to penetrate both bodies and defeat the opponent. But before his death, Raditz revealed that his two stronger Saiyan companions had learned through detectors that he had been killed and would invade Earth a year later.
