Background / History

During Frieza's assault on Namek, Goku fights Frieza directly while Piccolo, Krillin, Gohan, and later Ron observe from nearby. He recognizes that the Saiyans’ destruction followed the crimes of their race, but refuses Frieza's offer to join him. 4

Outmatched by Frieza's suppressed power, Goku repeatedly escalates his Kaioken. His twentyfold Kaioken and Kamehameha can injure Frieza, but cannot defeat him; the recoil leaves Goku badly hurt. 7 10 11

When Frieza prepares to destroy Namek, Goku proposes combining forces with Ron to buy time for the others to escape. He is initially unable to grasp Ron's true strength, but witnesses Ron halt the Planet Destroyer Bomb and transform into a Super Saiyan. 20 21 23 24

The Grand Elder later unlocks Goku's potential. Three days afterward, Goku seeks out Ron for a sparring match, hoping to test himself and learn from a stronger Saiyan. The defeat exposes the distance between them and becomes a turning point in his training. 43 47 49

Goku and Piccolo later fight Cooler together on Namek. Goku uses twentyfold Kaioken to support Piccolo, but both are decisively defeated before Ron intervenes. 73 74

Under Whis's guidance, Goku ultimately achieves the Super Saiyan transformation. He immediately battles Vegeta to test their new forms; their fight ends without a victor, establishing them as acknowledged rivals. 117 118

Appearance

Goku is a Saiyan martial artist who normally wears a martial arts uniform. During Kaioken, he is surrounded by a deep-red aura; upon becoming a Super Saiyan, his energy manifests as a towering pillar of light. 7 11 117

• Possesses a powerful yet restrained Super Saiyan aura, contrasting Vegeta's more domineering energy. 117
• His Kaioken aura dissipates after sustained maximum output. 11 74
• Prefers his own martial arts uniform and has Piccolo recreate it after it is damaged. 54

Personality

Goku is compassionate even toward former enemies. He intervenes when Piccolo humiliates Vegeta, asking that Vegeta be given a chance to change because he wants a fair future fight with him. 38

He is intensely battle-driven and eager to improve, readily challenging Ron despite knowing the vast difference in their strength. He accepts being outclassed without resentment and treats the experience as a lesson. 47 49 54

Although he appears simple-minded, Ron recognizes that Goku is observant and perceptive. Goku quickly identifies Instant Transmission's reliance on sensing a target's ki and cautiously probes Ron's motives before accepting him as a training companion. 32 34

Sparring with Ron

After the Grand Elder unlocks his potential, Goku challenges Ron to assess his growth. He uses Kaioken up to twentyfold and forces Ron to use the Blood Burning Technique, but learns that raw confidence and predictable attacks limit him. 43 49 50 51 52

Trivia

• Despite having sufficient base strength and S-Cells, Goku cannot become a Super Saiyan until he overcomes the final emotional and mental barrier. 73 95
