A strong Saiyan warrior, Raditz comes to Earth originally to look for his brother, Goku. Angry and intolerant, Raditz can't understand why it has taken so long for his little brother to destroy the humans. Ruthless like all the Saiyans, he reveals that two even more powerful Saiyans will be coming to Earth in one year in order to destroy it. Unfortunately, his Scouter transmits information about the nature of the Dragon Balls to the Saiyans.
