On a version of Earth in Universe 7, a monkey-tailed boy named
Goku befriends a teenage girl named
Bulma, whom he accompanies to find the seven Dragon Balls (ドラゴンボール Doragon Bōru), which summon the dragon
Shenlong to grant the user one wish. The journey leads them to the desert bandit
Yamcha, who later becomes an ally;
Chi-Chi, whom Goku unknowingly agrees to marry; and
Emperor Pilaf, an impish man who seeks the Dragon Balls to fulfill his desire to rule the world. Goku then undergoes rigorous training regimes under the martial arts master
Kame-Sen'nin in order to fight in the Tenkaichi Budōkai (天下一武道会, "Strongest Under the Heavens Martial Arts Tournament"). A monk named
Kuririn becomes his training partner and rival, but they soon become best friends. After the tournament, Goku searches for the Dragon Ball his grandfather left him and almost single-handedly defeats the
Red Ribbon Army and their hired assassin
Taopaipai. Thereafter Goku reunites with his friends to defeat the fortuneteller
Baba Uranai's fighters and have her locate the last Dragon Ball to revive a friend killed by Taopaipai.
At the Tenkaichi Budōkai three years later Goku and his allies oppose Kame-Sen'nin's rival and Taopaipai's brother, Tsuru-Sen'nin, and his students
Chaozu. Kuririn is killed after the tournament and Goku tracks down and is defeated by his killer,
Piccolo Daimao. The samurai
Yajirobe takes Goku to the hermit
Karin, where he receives healing and a power boost. Meanwhile, Piccolo fights Kame-Sen'nin and Chaozu, leading to both their deaths, and uses the Dragon Balls to regain his youth before destroying Shenlong. Goku then kills Piccolo Daimao, who, just before dying, spawns his son/reincarnation
Piccolo. Karin then directs Goku to
Kami-sama, the original creator of the Dragon Balls, to restore Shenlong and revive his slain friends. Goku trains under Kami for the next three years, once again reuniting with his friends at the Tenkaichi Budōkai, where he narrowly wins against Piccolo before leaving with Chi-Chi to keep his promise to marry her.
Five years later, Goku is a young adult and father to his son
Raditz arrives on Earth, identifies Goku as his younger brother 'Kakarrot' and reveals to him that they are members of a nearly extinct extraterrestrial race called the Saiyans (サイヤ人 Saiya-jin), who sent Goku to conquer Earth for them, until he suffered a
severe head injury and lost all memory of his mission. Goku refuses to continue the mission, sides with Piccolo, and sacrifices his life to defeat Raditz. In the afterlife Goku trains under the
North Kaiō until he is revived by the Dragon Balls to save the Earth from the invading
Vegeta. In the battle Yamcha, Chaozu, Tenshinhan, and Piccolo are killed, and the Dragon Balls cease to exist. Kuririn and the galactic tyrant
Freeza learn of another set of Dragon Balls on planet Namek (ナメック星 Namekku-sei), whereupon Bulma, Gohan, and Kuririn search for them to revive their friends and subsequently the Earth's Dragon Balls, leading to several battles with Freeza's minions and Vegeta, the latter standing alongside the heroes to fight the
Ginyu Force, a team of mercenaries. The long battle with Freeza himself comes to a close when Goku transforms into a Super Saiyan (超サイヤ人 Sūpā Saiya-jin) of legends and defeats him, with Namek being destroyed in the process.
A group of
Androids (人造人間 Jinzōningen, "Artificial Humans") created by a member of the former Red Ribbon Army,
Doctor Gero, appear three years later, seeking revenge against Goku. During this time, an evil life form called
Cell also emerges and, after absorbing two of the Androids to achieve his "perfect form," holds his own fighting tournament to challenge the protagonists. After Goku sacrifices his own life to no avail, Gohan avenges his father by defeating Cell. Seven years later, Goku, briefly revived for one day, and his allies are drawn into a fight against
Majin Boo. After numerous battles, including destruction and re-creation of the Earth, Goku destroys Boo with a Genki-Dama (a sphere of pure energy drawn from all intelligent beings on Earth) and wishes for him to be reincarnated as a "good person." Ten years later, at another Tenkaichi Budōkai, Goku meets Boo's human reincarnation,
Oob. Leaving their match unfinished, Goku departs with Oob to train him to be Earth's new guardian.
Six months after the defeat of Majin Boo, Earth was at peace one again. Goku became a radish farmer, Krillen a father, Gohan married to Videl, and Vegeta spent more time with his family. After thirty–nine years of slumber,
Lord Beerus, the God of Destruction of the universe, had awoken to a prophecy of a warrior emerging that would rival his power being known as a Super Saiyan God (超 スーパーサイヤ人ゴッド Sūpā Saiya-jin Goddo). Beerus along with mentor/servant
Whis took course to find Goku and Vegeta to fulfill the prophecy. Goku along with the rest of the sayians Including Gohan and Videl's soon to be born
daughter, united to have Goku achieve the Super Saiyan God form through a ritual revealed by Shenron.
Goku with his new power faced the God of Destruction with Earth's destruction at stake. Although Goku defeated, Beerus spares Earth and looks forward to Goku being more powerful.
A year has past since the encounter with Beerus. Goku and Vegeta had been training under Whis who had taken them as his students to master on controlling their flow of energy, maintaining it from within themselves. During this time, the remaining remnant of Frieza's army had went to earth to use the dragon balls to revive the long dead galactic ruler. Being revived and regenerated from the army's latest technology of regeneration, Frieza had began to plot his revenge on Goku who had defeated him on planet Namek. Learning that he had defeated Majin boo, one of two beings warned not to fight with from his father; the other being Beerus, Frieza decided to begin intense training to reach new heights of power to face Goku. Frieza's army had arrived on Earth while Goku and Vegeta still training with Whis. Tien, Piccolo, Gohan, Krillin, and Master Roshi had fought the remnant until their return. Once arriving on Earth, Frieza and Goku had fought showing their latest forms and power. Goku achieved a form beyond the Super Saiyan God form being the Super Saiyan God Super Saiyan (Super Sayian Blue). Frieza revealed his new form achieved after training stating he has not done before, calling it his Golden form.
Freiza became a handful with Goku but was bested yet again. However, with his Commanders help, defeated Goku with a severe shot when he was no longer focused. Vegeta then came in to fight Frieza being able to transform to the form as well. Vegeta outmatched Frieza showing the flaw of his new form where his body hasn't been used to the energy that gets consumed. Out of desperation, Frieza had destroyed Earth but with Whis' do over ability, Goku was able to prevent Frieza from destroying the Earth after being too over confident against him in the first place and destroys him once more.
After Frieza's return, Lord Champa and Vados appears who are Beerus and Whis' relatives. Also being the God of Destruction and Angel of Universe 6. Champa arrived to Beerus' home to see whose universe was superior. Eventually settled in a tournament with the two universes' fighters who were selected by the Gods of Destruction.
