The Saiyans had sent Goku (originally named "Kakarrot") to Earth as an infant to conquer the planet for them, but he suffered a head injury soon after his arrival and lost all memory of his mission, as well as his blood-thirsty Saiyan nature. Goku refuses to help Raditz continue the mission and has to team up with Piccolo, and sacrifice his life, in order to defeat him. However, Goku is revived a year later by the Dragon Balls, after training in the afterlife with King Kai, in order to save the Earth from the Saiyan prince Vegeta. However, in the battle Yamcha, Chaozu, Tenshinhan and Piccolo are killed. Due to Piccolo being one with Kami, the Dragon Balls no longer exist, resulting in a group traveling to their home planet, Namek, in order to use the balls there to revive their friends. However, the galactic tyrant Freeza is already there doing the same, leading to several battles with his minions and Vegeta, the latter of which teams up with the heroes to fight the Ginyu Force. After Goku arrives, the final long battle with Freeza himself comes to a close after Goku transform into a legendary Super Saiyan and avenges the lives of billions across the galaxy
