Raditz is a character that appeared in only few episodes in season one of Dragon Ball Z. Raditz is the brother of Goku, and is the eldest son of Bardock. Saiyan Saga. Raditz had traveled to Earth to check on his brother Kakarot, as he he had been named by in the planet Vegeta.
Raditz was also worthless remnants of freeza's army and I doubt Roshi has caught up to him. I remember when Goku was so strong and fast pre-SS that 2 of the fastest beings in the universe jayce and burter couldn't keep up with his movements. Gohan could have neck chopped 100,000,000 worthless army nobodies before they could move. They dumbed down Gohan and Buffed up Roshi for a fight scene.
