Long ago in the mountains, a fighting master known as Son Gohan discovered a strange boy whom he named Son Goku. Gohan raised him and trained Goku in martial arts until he died. The young and very strong boy was on his own, but easily managed. Then one day, Goku met a teenage girl named Bulma, whose search for the mystical Dragon Balls brought her to Goku's home. Together, they set off to find all seven and to grant her wish.
