Early Life
Kakarot was born sometime in Age 737 on Planet Vegeta, during a time of great turmoil. Following a Saiyan custom, Kakarot was sent as a baby to planet Earth, in order to destroy its inhabitants and clear the planet for its future sale. As Earth's inhabitants were thought to be weak, a baby Saiyan was seen as enough for the task, especially after transforming into a Great Ape by Earth's full moon. Kakarot's father, a low-class Saiyan warrior named Bardock, perished in his home planet's destruction shortly after Goku's departure, and his older brother Raditz was nowhere to be seen. It is unknown what happened to Goku's mother.[30] Goku, found alone in the forestAdded by Piccolo30After crash-landing on Earth, the baby was found in the woods by an old man named Gohan and became his adopted grandson. He was then given his Earthling name, Goku. At first, Goku was extremely violent and ill-tempered, not obeying Gohan at all, but one day he fell down a deep ravine and hit his head, suffering severe head trauma that sent him into a coma and very nearly killed him. After he woke up, he had lost all of his Saiyan aggression, becoming a kind and mild-mannered young boy.His Grandpa Gohan taught him martial arts and told him about such things as the city and people, as they lived in a very remote place in Mount Paozu, with no communication with other people.

Gohan one day discovered Goku's full moon transformation, and thus told him to never look at the full moon. However, one night Goku did, and he transformed into a Great Ape, causing him to unknowingly kill Gohan. After his grandpa's death, Goku stayed at his home, carrying out his daily life of survival. From a young age, Goku developed the impression that his birth parents abandoned him in the mountains as a baby, leaving him for Grandpa Gohan to discover.
