Background / History

Saiyan Childhood

Goku and his sworn brother were sent to Earth and adopted by Grandfather Gohan. Their families had agreed that the children would become sworn brothers if both were boys. Goku claims the older-brother position because their grandfather retrieved him from his spaceship first, although his companion sometimes introduces himself as the elder 1.

During childhood roughhousing, Goku fell into a valley and struck his head. The injury erased his memories and left him markedly frank and straightforward. Before formal instruction under Roshi, the brothers largely relied on Saiyan strength and basic punches despite the foundation their grandfather had given them 2 5.

Dragon Ball Search and Kame Style Apprenticeship

Bulma’s arrival begins the brothers’ Dragon Ball journey. Goku initially protects the Four-Star Ball anxiously, but becomes enthusiastic when told that gathering the balls could bring their grandfather back 1 2.

During the journey, he hunts with Ribut, receives the Flying Nimbus, and becomes Roshi’s disciple. His effortless imitation of the Kamehameha astonishes Roshi, who immediately agrees when Goku’s brother suggests giving him an early training foundation 7 13 14 32.

The brothers later receive martial arts advice during a temporary reunion with their grandfather. Goku’s attachment persists afterward: his brother notices him repeatedly rubbing the stone Dragon Ball while thinking about Grandfather Gohan 39 106.

Tournaments and Independent Training

After eight months of weighted training, Goku participates in the 21st World Martial Arts Tournament. His semifinal against his sworn brother features ki blasts and a fierce exchange of techniques; he loses but acknowledges the victory without becoming discouraged 51 74 75.

He subsequently borrows the Dragon Radar to recover the Four-Star Ball and travel the world. The journey follows his brother’s suggestion that independent adventure would broaden his experience and temper his character 80.

After fighting alongside his brother during the King Piccolo crisis, Goku sets out for further training. Chichi accompanies him to Korin Tower, and he eventually studies at Kami’s Lookout. He returns after a year and a half and later faces Piccolo in a tournament final; the supplied passages do not establish that match’s winner 100 104 110 116 126 140 141.

Marriage and Earth’s Defense

Goku and his brother establish the Kame Style dojo headquarters in West City and plan a joint wedding. By this point, Goku has accepted Chichi as his wife after years of emotional adjustment. He later becomes a father and cares for Chichi and their newborn son, Son Gohan 149 161.

While his brother travels into space, Goku remains on Earth as its guardian. When Raditz arrives, Goku knocks him unconscious with one punch, then spares him and visits daily to help him recover 163 173.

A Crusher Fruit increases Goku’s strength before the Ginyu Force confrontation. He easily overpowers Captain Ginyu, but his brother must intervene to stop Ginyu’s attempt to take his body 179 181.

With Frieza approaching, Goku trains with Vegeta in the Hyperbolic Time Chamber. He emerges eager to become a Super Saiyan and later accompanies his brother into space to confront the invasion 184 185 186 188.

Majin Buu and Gogeta

During the encounter with Dabura, Goku wants to help Vegeta but follows his brother’s advice to trust Vegeta’s abilities. He later watches his brother test techniques against Majin Buu and eagerly requests a turn against the unusually durable opponent 242 251 253.

As a Super Saiyan 3, Goku repeatedly destroys Buu’s body and wears down the energy sustaining his regeneration. When Buu is reduced to a barely living miniature form, Goku allows him to speak rather than immediately delivering the final attack 254.

A year after Buu’s destruction, Goku and Vegeta regularly fuse into Gogeta to challenge Goku’s brother. The relentless sparring contributes to the latter’s decision to leave Earth for a journey with Bulma, with Gogeta left to guard the planet 259.

Alternate-Timeline Counterpart

In the ruined future visited by Goku’s sworn brother, Goku has already died. His contributions to Earth earned him a physical body in the Other World, where he continues traveling and training. Porunga cannot resurrect this counterpart because of a time paradox 201 203 204.

Appearance

• Childhood build: Small enough to serve as a disguised substitute for a village girl during the Oolong trap 16.
• Saiyan tail: A genuine, movable tail, explicitly identified as a racial trait rather than an accessory 1 7.
• Later growth: Taller when he returns from his extended training at Kami’s Lookout 126.
• Training clothing: Wears a Kame Style martial arts uniform during his sparring with Piccolo 158.
• Later transformed appearance: Displays golden ki during battle and is described with emerald eyes during the aftermath of the Buu confrontation 254 256.

Personality

Goku is straightforward, food-driven, and often oblivious to social implications. He complains about being unable to eat Ribut’s dragon meat and fails to understand Bulma’s teasing about Chichi’s affection. His simplicity also accompanies a clear heart that impresses Roshi and allows him to ride the Flying Nimbus 6 13 33.

His competitiveness rarely turns into bitterness. He remains carefree after his tournament loss, celebrates his brother’s Super Saiyan breakthrough, and immediately sets his sights on achieving the same transformation. He nevertheless openly wants to surpass his brother and enthusiastically seeks durable opponents 75 181 185 253.

Goku’s kindness extends beyond fighting companions. He nurses Raditz despite their hostile first encounter, supports Yamcha’s decision to pursue baseball, and gives the exhausted Mini Buu an opportunity to speak. His determination to grow stronger is also tied to protecting Earth and the people close to him 173 179 254.

King Kai’s Techniques
