Power Progression

Stage / Realm / Level	Chapter	Notes
Kaio-ken training	2	Catches Gregory on King Kai’s Planet and begins learning the Kaio-ken, a technique that multiplies combat power and speed at severe physical cost.
Kaio-ken x3–x5	9	With a base power of roughly 5,000–6,000, reaches x3 against Vegeta, then forcibly pushes to x5 for an amplified Kamehameha; the backlash leaves him severely injured.
Post-recovery base power	14	His near-death battle with Vegeta raises his combat power to approximately 18,000. He remains unable to safely control higher Kaio-ken multipliers due to accumulated bodily damage.
Gravity Chamber training	20	Raises his combat power to around 3 million while training aboard the Namek-bound spaceship.
Grand Elder potential unlock	21	The Namekian Grand Elder unlocks his latent potential, raising his combat power to approximately 5 million.
Kaio-ken x10–x15	29	Uses tenfold Kaio-ken to reach about 50 million against Frieza and can potentially force the technique to fifteenfold, or roughly 75 million.
Super Saiyan prerequisite met	31	Reaches an estimated 10 million base combat power—enough to survive the transformation—but cannot initially trigger Super Saiyan without extreme rage or a method.
Super Saiyan	38	Learns Vegeta’s spine-focused transformation method and becomes a Super Saiyan for the first time. His 10 million base power rises to roughly 500 million.
Post-Namek Super Saiyan growth	41	Gravity Chamber training raises his base power to about 60 million; as a Super Saiyan, he reaches approximately 3 billion.

Appearance

Goku commonly wears an orange martial-arts gi. On Namek, he removes his weighted inner clothing and shoes before fighting Frieza. 19 29

• Orange martial-arts uniform 19 29
• Uses weighted training garments during combat preparation 29
• His face strongly resembles his father, Bardock. 24

Personality

Goku is driven primarily by combat and self-improvement. Rather than being discouraged by defeat, Vegeta’s overwhelming strength gives him a new rival to pursue, while the prospect of battling Frieza excites him even when he recognizes the danger. 14 16 29

He is compassionate to a fault. He offers enemies opportunities to leave alive, including Frieza and King Cold, but his habit of lowering his guard repeatedly creates danger for himself and his allies. Piccolo criticizes this carelessness during their spar, and King Cold nearly kills Goku after Goku spares him. 14 24 42

As Gohan’s father and trainer, Goku pushes his son to develop his ki and fighting ability, but also recognizes when Gohan has overextended himself and orders him to rest. 15

Story Role / Major Arcs

Saiyan Conflict

While on King Kai’s Planet, Goku trains to catch Gregory and learns the Kaio-ken. He returns from the Other World after the Z Fighters are devastated by Nappa, receives Senzu Beans from Korin, and heads directly to the battlefield. 2 7

Goku faces Vegeta alone after sending Piccolo to protect Tien and Yamcha’s bodies. He pushes Kaio-ken beyond his limits but loses after Vegeta overwhelms his Kamehameha with the Galick Gun. Vegeta leaves him alive, and Goku is hospitalized with shattered bones. 9 10

Training for Namek

After recovering through a Senzu Bean, Goku trains in the Hyperbolic Time Chamber with Gohan. His rivalry with Vegeta motivates him to keep improving, even after realizing Vegeta remains far stronger. 13 14 16

During the journey to Namek, he trains in the Gravity Chamber until he reaches a bottleneck, increasing his power to around 3 million. 20

Namek and Frieza

The Grand Elder unlocks Goku’s potential, raising him to roughly 5 million combat power. Goku then helps Gohan and Krillin defeat the Ginyu Force, narrowly avoiding Ginyu’s Body Change through Vegeta’s intervention. 21 23

Goku battles Frieza repeatedly, relying on Kaio-ken to compensate for the difference in base power. He reaches 50 million with tenfold Kaio-ken and may force himself to 75 million at fifteenfold. 24 29

Though he has enough base power to survive a Super Saiyan transformation by the end of the Namek conflict, Vegeta is the one who transforms first. Goku leaves Namek with Gohan and the others. 31

Super Saiyan Training and Frieza’s Return

Goku later asks Vegeta to teach him the Super Saiyan transformation. He successfully transforms, but Vegeta defeats him without transforming and explains that raising base combat power is more important than relying solely on multipliers. 38

After further Gravity Chamber training, Goku raises his base power to around 60 million and reaches roughly 3 billion as a Super Saiyan. He confronts Mecha Frieza on Earth and defeats him, but is nearly killed after sparing King Cold. 41 42

Future Warning

Future Trunks reveals that Goku is fated to die from heart disease in his timeline. Goku reacts more strongly to the thought of missing future battles than to the danger itself, but Trunks provides medicine that can cure the illness if it manifests. 40 43
