Chapter Summaries

Key plot points and events

• Piccolo challenges Goku, but backs down after seeing Goku’s immense power. Goku demonstrates Super Saiyan and then raises his strength with Kaioken, eventually revealing that he can reach a 300-fold multiplier.
• Piccolo learns that Goku’s base power is just over 90 million. Though surprised that he has not closed the gap, Piccolo takes pride in having grown more than twentyfold after assimilating Slug.
• Goku and Piccolo return to Earth. Six months later, Goku uses Earth’s Dragon Balls to revive the Namekians killed by Slug, then visits Namek and obtains a new set of wishes from Porunga.
• Goku wishes for adjustable-gravity training clothes, unlimited stamina, and knowledge of the divine language. He continues training, mastering the full-power Super Saiyan state and, two months later, successfully transforming into Super Saiyan 2.
• Vegeta, Goshin, and Gohin adapt to 300-times gravity. Their power rises to roughly three million, and all three achieve Super Saiyan after several attempts.
• King Kai warns Goku that Turles is spreading Trees of Might and destroying planets. Goku agrees to stop him.

Character developments and interactions

• Goku remains confident and generous: he shows Piccolo his strength without forcing a fight, encourages him, and makes reviving the Namekians a priority. His training advances from full-power Super Saiyan to Super Saiyan 2.
• Piccolo recognizes the limits of his strength and prudently withdraws from the challenge. He accepts Goku’s encouragement and acknowledges his own substantial progress.
• Vegeta, Goshin, and Gohin demonstrate their growing discipline by adapting to extreme gravity and unlocking Super Saiyan.
• The new Namekian Grand Elder, Moori, warmly thanks Goku and willingly lets him use the Dragon Balls.

Significant themes

• Humility and honest self-assessment: Piccolo chooses not to fight once he understands the gap between himself and Goku.
• Responsibility and gratitude: Goku uses his strength and the Dragon Balls to help the Namekians, then answers King Kai’s call to protect other worlds.

Plot points and events

• Acting on King Kai’s information, Goku uses Instant Transmission to find Turles and the Tree of Might.
• Turles assumes Goku might join his crew, but Goku announces that he intends to kill him and take the tree. When Turles’s subordinate Damondo scans Goku, his power level reads 530,000—already above Turles’s 500,000.
• Turles plans to stall long enough to eat more fruit. Goku explains that his strength comes from years of training rather than the tree’s fruit, then reveals that his displayed power is only a tiny fraction of his full strength.
• Goku transforms into a Super Saiyan, overwhelming the group; their Scouters explode when they cannot measure his power. Turles rushes for the tree, but Goku defeats him and his men.
• Goku eats one Spirit Tree Fruit, finding that it barely boosts his strength but greatly increases his godly power. He gathers all 250 fruits and takes Turles’s spaceship to Earth.
• Goku gives the spaceship to Dr. Briefs and shares fruit with him and Bulma. The fruit makes them feel younger and stronger; Bulma’s power level rises dramatically. Goku then begins distributing the remaining fruit to people he knows.

Character developments and interactions

• Goku is confident in his strength and dismissive of shortcuts, but he also treats the fruit as a useful gift for family and friends. He speaks warmly with Dr. Briefs and playfully flirts with Bulma.
• Turles is arrogant and scornful at first, then shocked by Goku’s strength. His reliance on the fruit contrasts with Goku’s disciplined training, and his attempt to stall shows his fear and opportunism.
• Dr. Briefs accepts Goku’s spaceship and fruit after Goku insists they are family. Bulma eagerly tries the fruit and responds to Goku’s teasing with playful embarrassment.
• Turles’s crew serves as the first measure of Goku’s overwhelming power; their surprise gives way to their defeat.

Significant themes

• Training versus shortcuts: Goku values earned strength, while Turles boasts about power gained through the Tree of Might.
• Power and restraint: Goku’s true strength far exceeds what he initially shows, making the fight one-sided.
• Family and generosity: Goku turns the spoils of victory into gifts for his loved ones, sharing both the spaceship and the fruit.

Plot and events

• Goku gives ten Spirit Tree Fruits to his allies, raising most of their power levels by roughly 300,000. The boost is especially significant for the Earthlings and other weaker fighters; it matters far less to the already powerful Saiyans and Piccolo.
• Goku continues intensive training. After six months in the 100-times Gravity Room, his base power reaches 990 million, and he can use 3,000-fold Kaioken. He plans to master Super Saiyan 2 before attempting Super Saiyan 3.

• Goku remains disciplined and wary of future threats despite his immense strength. He also keeps Trunks’s questions at a distance, pretending not to understand why Trunks expected him to arrive later.
• Vegeta is eager to prove himself in combat and confidently claims the right to face the newcomers alone. His pride is also the target of friendly teasing from Goku and Nappa.

• Cooler initially lands a punch, but Vegeta reveals he can transform into a Super Saiyan. The transformation shocks Cooler and King Cold.
• While the fight begins, Trunks is bewildered by this unfamiliar world: Vegeta can become a Super Saiyan, Goku has two sons present, and Raditz and Nappa are alive.
• Trunks speaks privately with Goku and reveals that he is from twenty years in the future, the son of Bulma and Vegeta. Goku corrects his assumptions about the family relationships in this timeline.

Character developments and interactions

• Vegeta continues overpowering Cooler, who reveals a previously unseen Ultimate Form. Cooler’s power rises sharply, surprising King Cold.

• Raditz starts in Super Saiyan form and deliberately holds back, allowing Android 19 to land a few hits and boast.
• When Raditz reveals the enormous gap between their strength, Android 19 is stunned. Raditz then destroys him with a punch followed by an energy blast, reducing him to dust.

Character developments and interactions
