Radditz
Radditz is the brother of Goku. He came to Earth before the Vegeta & Nappa Saga to find if Goku had destroyed the planet as his orders were supposed to be. But as you know, when he was little, he had a deadly fall that scrambled his memory. Radditz decided that since he didnt complete his orders, he knew that he will ahve to complete them for him, and he knew how to get it done. He had to find Goku, and take something that was dear to him. So he found Gohan and took him away and put him in his space pod for a while. Until his father and Piccolo teamed up to defeat this Angry Saiyan. The two barely were enough for him, Goku sacrificed his life to defeat Radditz. Goku grabbed Radditz and Piccolo charged and shot his Makankosappou and in went completely through Radditz and Goku. They both faded away. Goku then went to King Kaioh for training.
