Raditz

Raditz was one of the Saiyans that survived after Frieza blew up their planet.He worked for Frieza with Nappa and Vegeta.He was Goku's big brother,and he came to earth to tell him to join him.When Raditz found Goku,he was surprised that there are still humans on the earth.He told to Goku that he was supposed to conquer the earth many years ago,and that Goku has failed in his mission.Raditz told Goku all the things about his mysterious past.Goku just couldn't believe that.Raditz said that if Goku won't kill at least 100 humans until tomorrow,he will kill his little child,Gohan.Raditz kidnapped Gohan and Goku tried to attack Raditz,but Raditz gave him a single kick and told him that he has no other way to save his son.Then,Piccolo arrived and he and Goku decided to join forces to save the earth from Raditz.They flew after him,and began to fight him.But Raditz was faster and stronger than both Goku and Piccolo.And then,when Raditz was about to finish Goku,Gohan got very angry and he broke Raditz's spaceship and hit him with all his power.Piccolo took this chance and he pulled Raditz's tail,and he got weaker by it because it is the weakness point of the Saiyan.Goku grabbed Raditz around his body and told Piccolo to kill him when he is still holding him.Piccolo did his special Beam Cannon which passed through their bodies,and they died.Before he died,Raditz said that two stronger Saiyans will arrive after one year for revenge.
