The series begins with Goku and Bulma finding all seven Dragon Balls, which can summon the dragon Shenlong to grant the user a wish. Their journey takes them to many people like Yamcha, Chi-Chi (Goku mistakenly agrees to marry), and Pilaf, an evil man who seeks the Dragon Balls to grant his desire to rule the world. Goku then must go through intense training by Master Roshi to fight in the Tenkaichi Budōkai, a fighting tournament. A monk named Krillin becomes Goku's best friend and training partner. After the tournament, Goku looks for the Dragon Ball his adoptive grandfather left him and almost single-handedly takes down the Red Ribbon Army and their assassin Taopaipai. Goku reunites with his friends to defeat fortuneteller Baba's fighters to locate the last Dragon Ball to revive a friend killed by Taopaipai.
