Dragon Ball

The series begins with a young monkey-tailed boy named Goku befriending a teenage girl named Bulma. Together, they go on a quest to find the seven magical Dragon Balls. Along the way, they meet and befriend a plethora of martial artists. Goku also undergoes rigorous training regimes and educational programs in order to fight in the World Martial Arts Tournament, a competition involving the most powerful fighters in the world. Outside the tournaments, Goku faces diverse villains such as Emperor Pilaf, the Red Ribbon Army, the evil Namekian Piccolo Daimao and his offspring Piccolo Jr., who eventually becomes Goku's ally and close friend.
As a young adult, Goku meets his older brother Raditz, who reveals to him that they are members of a nearly extinct extraterrestrial race called Saiyans. The Saiyans had sent Goku to Earth as an infant to conquer the planet for them, but he suffered a severe 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, after which he begins to encounter other enemies from space, most notably the Saiyan prince Vegeta, who becomes his rival due to Vegeta's obsessive desire to surpass Goku in strength, though in the process, he too eventually becomes Goku's ally. Goku also encounters Frieza, the galactic emperor responsible for the destruction of the Saiyan race, whose actions cause Goku to transform into a fabled Super Saiyan. After an epic battle on the planet Namek, Goku defeats Frieza, avenging the lives of billions across the galaxy.
Some time later, a group of androids from the former Red Ribbon Army appear, seeking revenge against Goku. During this time, an evil life form called CellSon Gohan emerges and, after absorbing two of the androids to increase his power, holds his own fighting tournament to decide the fate of the Earth, but is eventually defeated by Goku's first child . Seven years later, Goku is drawn into another battle for the universe against a magical monster named Majin Buu. After many battles, Goku destroys the evil original Majin Buu and the good part of Buu settles down with them. Ten years later, at another World Martial Arts Tournament, Goku meets the evil Buu's human reincarnation, Uub. Leaving the match between the two of them unfinished, Goku takes Uub away on a journey to train him as the Earth's next defender.
