Songoku's Saiyan name is Kakaroct. Kakaroct was classified as a low class Saiyan. He only  had a power level of 2 when he was born. This dissapointed his father, Bardock, very much. Kakaroct was then sent to destroy all the creatures on earth when he was still a baby. To the Saiyans, earth is a very weak planet and so they sent a low class Saiyan such as Kakaroct there. On earth Goku was then found by Songohan. Songohan then named Kakaroct, Songoku as he didn't know Goku's real name. Songohan found Songoku a very strange child because Songoku has a tail but yet he still treated Songoku as one of his own. As a Saiyan, Songoku has a really bad attitude in the beginning. Then one day, Songoku fell and his head bumped on a rock. Since then Songoku began to act like a normal kid. Songoku met Bulma when Bulma was on the hunt for the Dragonball. Songoku , at that time had the Fourth Dragonball so eventually they both met. As someone who has never seen another gender, he was very suprised to see a girl. Bulma was also suprised to see Songoku because he had a tail. Later on, Bulma managed to convince Songoku to come with her and hunt for the Dragonball. This is where the story starts.While finding the Dragonball, Songoku also made some other friends such as Yamcha, Wuloong, Mutenroshi and Puaru. After they had finally found all the Dragonball. They all split up. Bulma went off with Yamcha along with Wuloong and Puaru. Songoku then went to Mutenroshi to  learn Martial arts. Later on , Goku meets Kulilin and they become friends .Goku managed to destroy a big army organization named Red Ribbon.  Goku grew up and became very strong.He experienced many battles concerning Earth's fate. He fought Piccolo Daimao , a demon who wants to rule over earth and turn it into Hell. After defeating Piccolo Daimao he fought Piccolo Daimao's son at the Tenka-Inchi-Budokai. Goku won the match as well as another girl's heart, Chi-chi and they both got married and had a son.Goku named his son Songohan. Five years later, Songoku's Brother, Radeitz went to earth and revealed all Goku's life history.Radeitz forced Goku to follow him along with some other Saiyans to conquer the universe. Goku than had to pair with Piccolo to kill his own brother. Unfortunately Songoku died in the process.After knowing Radeitz Death two remaining Saiyans decided to go to earth and destroy the Planet. In the 'Other dimension'(yeah right) Goku learned Martial arts with Master Kaio for about a year .
