Summary of “Sabaody Battle (2)”

Key Plot Points and Events

• Donquixote Sun discovers that William survived and is aboard the Thousand Sunny. Furious, he orders Leo to destroy the Straw Hat Crew, threatening punishment if they escape.
• The Marines nearby react uneasily to Sun’s authoritarian attitude, though they are forced to obey because the Marines serve the World Government and Celestial Dragons.
• The Thousand Sunny prepares its Lion’s Roar Cannon. Fearing its destructive power, Sun orders his escort ship to move.
• The cannon narrowly misses the escort ship and devastates Island 4, blasting away earth and creating enormous waves. The resulting chaos gives the Thousand Sunny an opening.
• William orders Franky to activate the Sunny’s Outer-Wheel Drive and charge through the Marine and Celestial Dragon blockade. Although this risks allowing enemies to board the ship, it is their best chance to escape while waiting for Luffy and three other crewmates to return.
• The attack alarms civilians throughout Sabaody, while conflicting rumors spread about the Straw Hat Crew’s fate and location.
• On Island 1, Marines crush thousands of pirates associated with the fake Straw Hat Crew and the pirate Doughty.
• Meanwhile, the Caribou Pirates fight two Marine warships and nearly a thousand Marines. Caribou uses his Logia abilities and a hidden Gatling gun, while Coribou reflects cannonballs with his shovel.
• Caribou considers attacking the real Straw Hat Crew but decides against it after seeing them surrounded by more than ten warships. He and Coribou choose to remain hidden rather than risk suicide.

Character Developments

• William demonstrates tactical leadership by using the Lion’s Roar Cannon not primarily to destroy the enemy but to create a route through the blockade. He accepts the danger of close-quarters boarding because rescuing the missing crew members is more important than making a safe retreat.
• Donquixote Sun is shown as arrogant, vindictive, and dependent on Celestial Dragon authority. His personal hatred of William intensifies his determination to eliminate the Straw Hats.
• Franky follows William’s command and prepares the Sunny’s maximum-speed escape maneuver, despite recognizing the danger.
• Usopp remains cautious and points out that charging the enemy could allow them to board the ship.
• Caribou is portrayed as opportunistic but not entirely reckless. Though he wants to claim Luffy’s head, he recognizes that attacking the heavily surrounded Sunny would be foolish.
• Coribou acts as the more practical voice, advising his brother to lie low, while also proving capable in battle by deflecting artillery.

Significant Themes

• The abuse of authority: Sun’s treatment of the Marines exposes the Celestial Dragons’ absolute power and the resentment their privilege creates within the Marines.
• Justice versus obedience: The Marines may believe in protecting civilians, but their position requires them to follow orders from the World Government and Celestial Dragons.
• Strategy under pressure: William uses the Sunny’s weapon creatively, turning a missed shot into a tactical advantage.
• Reputation and misinformation: Conflicting reports about the Straw Hats spread rapidly, showing how confusion and rumor shape the battle.

• Caribou and Coribou debate whether to attack Luffy. Caribou is tempted by the opportunity, but Coribou persuades him that hiding is the wiser choice.

Summary of “Sabaody Battle (3)”

Key Plot Points and Events

• The Thousand Sunny, using the Dockyard Soldier System’s Outer-Wheel Drive, races toward Island 4 and the escort ship carrying the Celestial Dragon Donquixote Sun.
• The Marines are unable to fire on the Sunny because they fear accidentally damaging or frightening the Celestial Dragon. His presence disrupts their encirclement and gives the Straw Hats a potential escape route.
• Marine commander William exploits this hesitation by ordering Franky to steer toward the escort ship, using it as a shield against the Marine fleet.
• The Marines realize that their formation is collapsing and urgently attempt to reorganize. They also remember that the Sunny has been coated and can dive underwater, meaning they must sink it before it escapes beneath the sea.
• To prevent Donquixote Sun from coordinating the Marines, Nami unleashes Thunder Marquis. The lightning destroys the escort ship’s masts and gun emplacements, starts fires, paralyzes many personnel, and disables the Den Den Mushi.
• With the enemy temporarily disorganized, William’s plan is to use the escort ship as cover and dive into the sea.
• Donquixote Sun orders his forces to board the Sunny. More than five hundred P1 modified humans are stationed on his ship, and the first waves attack the Straw Hats.
• Luffy and Zoro combine their abilities, with Luffy launching Zoro into the air so Zoro can use Oni Giri to defeat the first boarding group.
• Sanji repels another wave with Diable Jambe: Scorching Iron Pot, then immediately resumes flirting with the women on the ship, irritating the rest of the crew.
• The Marines realize the Straw Hats are hiding behind the Celestial Dragons’ escort ship. Since they still cannot bombard it, four Marine warships close in to engage the Sunny through boarding combat.
• Across the Sabaody Archipelago, residents realize the conflict has escalated into a major battle. Most pirate ships have already been destroyed, and the ongoing bombardment and fighting cause widespread fear.

Character Developments

• William demonstrates strategic foresight and a willingness to exploit the Marines’ fear of the Celestial Dragons. He has anticipated Donquixote Sun’s threat and prepared Nami’s lightning attack as part of a broader escape plan.
• Nami successfully uses Thunder Marquis for a tactical purpose rather than simple damage: disabling communications, weapons, and enemy coordination.
• Donquixote Sun, despite being more intelligent than typical Celestial Dragons, displays their characteristic entitlement by blaming the Marines for the interruption instead of recognizing that his own presence is preventing them from attacking.
• Zoro is unusually tolerant of Luffy’s impulsive teamwork, suggesting he is in a particularly good mood.
• Sanji remains effective in battle but immediately returns to his comical obsession with beautiful women, reinforcing the crew’s chaotic dynamic.
• The Castle Army recruits begin questioning whether the Straw Hats are reliable future companions, though Nojiko views the situation with amusement and confidence.

Significant Themes

• Power and institutional paralysis: The Marines possess overwhelming force but are immobilized by the political power of the Celestial Dragons.
• Strategic exploitation of authority: William turns the Marines’ fear of their superiors into a defensive advantage for the Straw Hats.
• Chaos versus organization: The Straw Hats succeed through improvisation and teamwork while the Marines’ carefully planned formation collapses.
• Escalation of conflict: What began as an arrest operation becomes a large-scale battle affecting the entire archipelago.
• Comedy amid danger: Luffy, Zoro, and Sanji’s absurd teamwork and behavior contrast with the deadly military confrontation.

Character Interactions

• William directs Franky and Nami, coordinating the Sunny’s movement and Thunder Marquis attack.
• Donquixote Sun orders Leo and the P1 forces to capture the Straw Hats, but the lightning attack temporarily leaves him paralyzed and unable to command effectively.
• Luffy assists Zoro by launching him into the boarding enemies, allowing Zoro to perform Oni Giri.
• Sanji protects the ship alongside the others, then embarrasses the crew by flirting with the women.
• Chopper and Usopp warn the crew as new attackers approach, while the wider crew reacts with frustration to Sanji’s behavior.
• The Castle Army observes from within Castle Space, waiting for William’s order to join the battle.

• William deploys his "Castle Army" — dozens of beautiful women emerge from his body carrying wooden explosive barrels filled with timed cannonballs.
• William orders the explosive barrels deployed to destroy the Navy warships above, with a five-minute delay to allow sailors time to escape — showing the crew will harm enemies but not needlessly kill them.

Character Developments

• William: Demonstrates strategic brilliance as the Straw Hats' strategist; shows a moral compass by timing explosions to spare Navy lives rather than killing indiscriminately.
• Donquixote Sun: Introduced as a vengeful Celestial Dragon who refuses to accept defeat; prideful and obsessed with William's survival.
• Leo: Introduced as a confident, calculating strategist with hidden resources; implies significant future threat.

Significant Themes

• Mercy vs. annihilation: Pirates choosing to spare enemy soldiers despite having lethal means; William's refusal to embrace wanton destruction.
• The Navy's corruption: William argues the Navy has become a puppet of the Celestial Dragons, referencing Zefa's past to justify opposition.

Summary: “New Fish-Man Pirates”

Key plot points and events

The Straw Hat crew and their allies discuss the World Government’s decision to threaten war against Fish-Man Island after it withdrew from the organization. Nami explains that the Government has previously punished nations such as Amazon Lily with extreme measures, comparing its actions to the destruction of Ohara. The former slaves in William’s Castle Army are especially angered because the World Government and Marines tolerated the slave trade on Sabaody Archipelago.
William explains that although the Five Elders appear to rule the World Government, it ultimately serves the Celestial Dragons. Meanwhile, Luffy ignores the political discussion and enjoys observing the enormous sea creatures around the ship. The group is then approached by the New Fish-Man Pirates, led by Aladdin, who has come to welcome Jinbe and escort the Straw Hats to Fish-Man Island. Aladdin reveals that King Neptune is already waiting for them at the palace.

Character developments

Jinbe’s importance to Fish-Man Island becomes clear. Once a member of Neptune’s army and later a Shichibukai and Sun Pirate, he is now returning as a respected hero and the Straw Hat crew’s new helmsman. Aladdin warmly congratulates him for finally pursuing the life he wants.
Koala is revealed to have a personal history with Aladdin and the Sun Pirates. She is the human girl Fisher Tiger once rescued, and her connection surprises Usopp and the others. This deepens the crew’s understanding of Koala’s relationship with Fish-Men and her past with the Revolutionary Army.
Luffy immediately recognizes Aladdin’s strength, while Sanji becomes extremely excited at the prospect of meeting the mermaid princess. His attempt to appear refined quickly collapses back into his usual exaggerated behavior.

Significant themes

The chapter emphasizes the World Government’s hypocrisy and oppression, particularly its willingness to use “justice” and military force against nations that refuse to submit. It also highlights the lasting trauma caused by slavery and the resentment felt by former slaves toward the authorities that permitted it.
Another major theme is liberation and personal choice. Jinbe’s history shows him repeatedly sacrificing his own desires to protect others, and his new life with the Straw Hats represents a chance to follow his own path. The reunion with Aladdin and Koala also reinforces the bonds formed through shared suffering and resistance.

Character interactions

William and the crew debate the World Government’s actions, with Nami contributing knowledge from her continued contact with William. Jinbe warmly reunites with Aladdin, while Aladdin expresses pride in Jinbe’s decision to join the Straw Hats.

• Jinbe explains that Law has already been on Fish-Man Island for over a month and has been providing valuable medical assistance.
• Neptune’s decision to invite the Straw Hats, Law, and other pirate groups reflects Fish-Man Island’s need for powerful allies after leaving the World Government. Its existing alliances with the New Whitebeard Pirates and New Fish-Man Pirates are not considered sufficient protection.

• King Neptune is presented as both a powerful ruler and a politically pragmatic leader seeking alliances to protect his nation.

Significant Themes

• Political independence and vulnerability: Fish-Man Island’s separation from the World Government gives Neptune freedom but leaves the nation exposed to attacks and in need of strong allies.
• Alliance-building: The banquet serves not only as a social gathering but also as a diplomatic meeting between influential pirate groups and Fish-Man Island.
• Comedy versus danger: Luffy’s carefree eating and Sanji’s antics contrast with the serious political threats facing the island and Law’s suppressed hostility.
• Hidden power and secrets: Shirahoshi’s absence hints at the danger surrounding her identity as Poseidon, while William’s knowledge emphasizes the story’s deeper mysteries.

Key Plot Points and Events

• Luffy immediately agrees to form an alliance with Trafalgar Law, surprising Usopp and irritating Sanji, who feels excluded from such an important decision.

Summary: “Vander Decken”

1. Key Plot Points & Events

• The Ryugu Palace banquet for the Straw Hat Crew ends after three hours, mainly because Luffy and Jewelry Bonney eat nearly all the food.
• William suspects King Neptune is using the banquet to court the Straw Hats’ support, given Fish-Man Island’s dangerous position with the World Government and the fall of Whitebeard.
• Trafalgar Law, who has been on Fish-Man Island for over a month, was also invited—William concludes Neptune likely guessed Law was waiting for the Straw Hats.
• After the banquet:
  • Luffy, Zoro, and Sanji are reluctant to leave (food, booze, mermaids).
  • Nico Robin asks to see Fish-Man Island’s Poneglyph; Jinbe escorts her, with Chopper and Brook.
  • Aladdin of the New Fish-Man Pirates departs separately.
• William heads toward Fish-Man District, claiming he wants to visit a friend (Hachi).
• Law reveals key intelligence:
  • Hody Jones died three months ago fighting the World Government.
  • Vander Decken is Shirahoshi’s obsessed suitor, was seriously injured protecting her, and is currently missing.
• William reflects on both men:
  • Hody was once a royal soldier, embittered by racial hatred, and possibly involved in Queen Otohime’s assassination—but his death removes a future threat.
  • Vander Decken IX is a cursed fish-man who cannot swim and inherits the Target-Target Fruit ability through his family line.
• William notes that the Vander family’s Devil Fruit inheritance method resembles Blackbeard’s ability to steal Whitebeard’s power, and he sees potential value in learning that method.

2. Character Developments

• William: Acts as a strategist, gathering intelligence on potential destabilizing figures. He trusts Jinbe’s integrity and is skeptical of Neptune’s motivations. He is also deeply interested in the mechanism of Devil Fruit inheritance.
• Trafalgar Law: Serves as an information source, showing he has monitored Fish-Man Island’s undercurrents during his stay.
• Jinbe: Implied to have made some arrangement with Luffy; he remains protective and responsible, escorting Robin to the Poneglyph.
• Hody Jones / Vander Decken: Both are removed from the immediate picture—one dead, one missing—but their legacies/looming threats still weigh on William’s planning.

3. Significant Themes

• Political maneuvering: Neptune’s hospitality is not purely gratitude; Fish-Man Island needs powerful allies.
• Trust and judgment: William distinguishes between Neptune’s statecraft and Jinbe’s personal loyalty.
• Intelligence and control: William’s role as a strategist depends on knowing threats before they act.
• Legacy and power inheritance: The Vander Decken “curse” and Blackbeard’s Devil Fruit theft both point to methods of passing on power—knowledge William covets.
• Past and future threats: Hody’s death closes one danger, but Vander Decken’s disappearance leaves uncertainty.

4. Character Interactions

• William and Law walk together after the banquet and exchange information naturally.
• William deflects Law’s curiosity about his sources by attributing them to Hachi—knowing Hachi is forgetful and unlikely to contradict him.

• Jinbe continues to act as a guide/guardian for the Straw Hats.
• Aladdin’s quiet exit hints at ongoing Fish-Man District matters behind the scenes.

Chapter Summary

Key Plot Points and Events

• Trafalgar Law questions William about the World Government’s attack on Fish-Man Island. William summarizes the attack as an attempt to “eliminate dissidents,” though he privately suspects the government may know that Princess Shirahoshi is the Ancient Weapon Poseidon.
• Law asks about Monet and Baby 5. William reveals that they, along with another member of the Poker Army, have joined his group. He assures Law that they are not spies and that Doflamingo does not even know they survived or changed sides.
• Law questions why William remains under Luffy’s command instead of forming his own crew. William jokingly credits Luffy’s charisma and says he lacks ambition.
• The discussion turns to defeating Donquixote Doflamingo. William proposes attacking the Poker Army’s underground weapons trade, which interests multiple factions, including the Revolutionary Army.
• Law suggests using Kaido to eliminate Doflamingo, reflecting his own strategy of using an emperor’s power to obtain revenge.
• William argues for a more direct approach. Since Luffy and Law’s alliance already intends to take down Kaido, defeating Doflamingo could serve as both a first step and a means of provoking Kaido. William also reveals that he fought Doflamingo six months earlier.

Character Developments

• William demonstrates caution and political awareness by withholding his suspicions about Shirahoshi’s identity as Poseidon. He also shows confidence in Luffy and accepts the possibility of confronting powerful enemies directly.
• Trafalgar Law remains distrustful and strategically minded, carefully testing William’s motives and the loyalty of his companions. Learning that Monet and Baby 5 are not Doflamingo’s agents eases his concerns.
• Law’s motivation is reinforced: his primary goal is still defeating Doflamingo and avenging Rosinante, though he recognizes that he may need allies and indirect strategies to succeed.
• Luffy’s influence is emphasized. William suggests that Luffy’s charisma, rather than ambition or political calculation, is what keeps stronger individuals willing to follow him.

• Their conversation gradually shifts Law from suspicion toward cautious trust, especially after William explains Monet and Baby 5’s allegiance.

William explains that, six months earlier, he accidentally attracted the attention of the Poker Army in Dressrosa and was attacked by senior officers Pica and Diamante, followed by a battle with one of Doflamingo’s clones.
• William escaped largely because of Doflamingo’s arrogance. Had he faced the real Doflamingo at that time, he likely would not have survived.
• Law teasingly accuses William of abducting Doflamingo’s subordinates, referring to Baby 5 and possibly Monet. William avoids explaining how they came to join him.
• Before leaving Fish-Man Island, Law gives William special coral that allows humans to breathe underwater. They also use coating bubbles to survive the crushing pressure of the deep sea.
• Both men discover that seawater weakens them because they are Devil Fruit users. Although they can move underwater with the coral and bubbles, William estimates that they would fight at less than half their normal strength.

• Law: He acts as William’s practical guide and provides the coral needed for underwater travel. His teasing shows growing familiarity with William, while his warning about Fish-Man District demonstrates caution and awareness of the local danger.
• Fish-Man District residents: Their fear and hostility toward humans are emphasized, reflecting the effects of long-term discrimination, persecution, and the recent war.

• Trafalgar Law appears ready to retaliate when the Fish-Men insult William, highlighting his protective and easily provoked nature.
• The Tiger Shark Fish-Man is shown to be cautious and authoritative. Despite distrusting humans, he prevents his subordinate from escalating the situation and agrees to contact Hachi.
• Hachi is reaffirmed as loyal and grateful. Although he once fought against the Straw Hats as part of Arlong’s crew, he has changed through his friendship with them and his willingness to protect their ship.
• William and the Straw Hats’ former hostility toward Hachi has been replaced by forgiveness and mutual respect. Nami and Nojiko’s acceptance of him further reflects this change.
