Raditz
Raditz is a powerful Saiyan warrior from Planet Vegeta. He comes to Earth in search of a man he calls "Kakarot". Using his scouter, he finds Kakarot, who turns out to be Goku, and insists that he leaves Earth with him. When Goku refuses, he abducts his young son, Gohan, and demands that Goku slaughters 100 Earthlings if he ever wants to see Gohan again. A battle ensues, and Goku's enemy, Piccolo, joins forces with Goku to take down Raditz. Just when things are getting desperate, Gohan appears and sends an attack flying into Raditz's chest. Badly injured, Raditz is now vulnerable, and Piccolo finishes him off.
