Background

Goku lives on Bun Mountain when Ye Bai first meets him in the forest. He immediately accepts Ye Bai into his home and agrees to teach him martial arts; the two soon share daily training, meals, and spars. Goku hunts enormous fish and game, while Ye Bai introduces him to seasoned cooking and basic routines such as bathing properly. 1 2 4

At the beginning of the story, Goku is twelve years old despite believing that he is fourteen. His numerical confusion and untamed upbringing reflect his isolated childhood. 3

Appearance

Goku begins the story as a tailed Saiyan boy living in the wilderness. He later grows enough during his training that longtime friends initially mistake him for a stranger at the Twenty-Third World Martial Arts Tournament. 4 15

• Has a Saiyan tail; it is severed after his first Great Ape transformation, then later regrows. 5 9
• As a child, routinely carries game far larger than himself, including wolves, fish, and dinosaurs. 2 4
• His adult growth is significant enough that Bulma and the others initially fail to recognize him. 15

Personality

Goku is innocent, straightforward, and unusually trusting. He readily befriends Ye Bai, Bulma, Krillin, Cabba, and even considers allowing his invading brother Raditz to remain on Earth after rehabilitation. 1 4 21 93

His greatest passion is martial arts. He seeks difficult fights for their own sake, often holds back to study an opponent's techniques, and is willing to use battle as training even while outnumbered. 7 92 133 138

Despite his battle enthusiasm, Goku shows mercy after victory. He spares Vegeta after defeating him, praises Cabba after their match, and refuses Ye Bai's offer to resolve his Tournament of Power opponents for him. 22 94 146

His Saiyan instincts become more pronounced after transforming into a Super Saiyan: he develops an intense desire for a satisfying battle, though he can still respond to danger and protect others. 28

Abilities & Skills

Goku is an instinctive fighter with exceptional growth during battle. Ye Bai observes him improving at an astonishing rate during their tournament final, and Goku later adapts to the increased power of his Super Saiyan state while fighting Ye Bai on Namek. 19 28

Ki Control and Sensing

Goku learns to sense ki from Ye Bai during their first World Martial Arts Tournament final. 9
