Chapter Summaries

Key plot points and events

• Vegapunk releases an ancient mechanical war machine, the Leviathan, from dormancy beneath Egghead. More than five thousand meters long, it races toward Wano, protected by a powerful heat-repulsion system and an unfamiliar composite shield.
• News and intelligence vessels report the machine’s approach, and the World Government’s hidden weapon becomes the talk of the seas.
• At Wano, JARVIS detects the Leviathan. Tony attacks with Eclipse’s orbital cannons, but their beams barely affect its shield.
• Tony identifies the defense as a spatial-distortion system that redirects incoming energy. Rather than destroy the Leviathan, he hopes to capture it and reverse-engineer its technology.
• To stop it before it reaches Wano’s port, Tony removes the limiter on the underground No. 2 Ark Reactor and raises its power output to 120 percent. The chapter ends as the reactor enters full overload.

Character developments

• Vegapunk reveals the World Government’s hidden reliance on ancient machinery, presenting the Leviathan as a weapon built to counter Eclipse.
• Tony shifts from confident dismissal to fascinated admiration when the Leviathan withstands his attack. His curiosity and ambition lead him to prioritize acquiring its technology.
• Kahn remains calm and pragmatic, supporting Tony’s plan while stressing the need to protect Wano’s newly repaired port.
• Sabo recognizes the threat’s immense scale, while Ace offers to attack it with heat. Tony rejects brute force in favor of studying its shield.
• Luffy reacts with characteristic simplicity, wondering if the enormous machine can be eaten; Tony scolds him.

Significant themes

• Ancient technology versus modern innovation: Both sides wield extraordinary technology, and the Leviathan’s defenses prove that the ancient world may rival—or surpass—modern systems.
• Power and escalation: The orbital attack fails, prompting Tony to push Wano’s reactor beyond its normal limit.
• Weaponry as opportunity: Tony sees the Leviathan not only as a danger but as a potential source of technology that could strengthen Eclipse’s armor.

Character interactions

• Tony’s exasperated banter with Luffy provides comic relief amid the looming danger.
• Sabo and Ace voice the group’s concern and propose direct responses; Tony answers with technical analysis instead.
• Kahn and Tony work as pragmatic allies: Kahn sets the strategic priority of protecting Wano, while Tony takes charge of stopping the Leviathan.

Plot points and events

• In Wano’s underground energy chamber, Tony forces Enel to power the Arc Reactor with lightning, using a neck collar to keep him supplying energy. Enel protests, but Tony promises him extra apples if he keeps going.
• As the enormous mechanical Leviathan approaches Wano, Tony orders the orbital defense satellites to fire. Thirty-two satellites launch particle beams at the machine.
• Vegapunk insists that Leviathan’s Ancient Kingdom deflection field can withstand the attack. The shield does deflect the first barrage, though the impacts slow Leviathan only slightly.
• Tony analyzes the shield’s response and identifies a brief energy-refresh delay at a folding node beside Leviathan’s left gill. He directs the satellites to concentrate their fire there.
• The focused beam strikes the weak point, cracks the field, and shatters the shield, leaving Leviathan’s armor exposed.

Character developments and interactions

• Tony demonstrates confidence in modern technology and quick, strategic thinking, turning the failed barrage into a precise attack. He banters with Enel and dismisses Ace’s offer to fight with fire.
• Enel is resentful and coerced into serving as Tony’s power source, but continues supplying electricity under threat.
• Vegapunk expresses strong faith in the Ancient Kingdom’s technology, declaring it superior to Stark’s weapons; the shield’s eventual collapse challenges that certainty.
• Sabo tracks Leviathan’s approach and recognizes the destructive scale of the satellite attack.
• Luffy jokingly wonders whether Leviathan contains edible fish, while Ace pulls him away and explains that it is machinery. Ace also offers to attack, but Tony rejects the idea.
• Kahn cautions Tony against recklessness, reminding him of the cost of Wano’s breakwater.

Significant themes

• Science versus ancient technology: Tony’s orbital weapons initially seem unable to overcome an advanced ancient defense, but careful analysis reveals a flaw.
• Power and coercion: Enel’s lightning is harnessed through force, making him both a powerful contributor and a captive resource.
• Adaptability over brute force: The decisive breakthrough comes from identifying and targeting a tiny weakness rather than simply increasing destructive power.

Key events

• Leviathan charges its superheavy laser cannon, threatening to devastate Wano’s surrounding ecosystem.
• Kahn intervenes at the last moment, crushing the machine’s head with a single blow and forcing it underwater, where its cannon discharge is smothered.
• Tony deploys fifty Anti-World Government Armor units. Their chains and electromagnetic brakes immobilize Leviathan, and they tow it to Wano’s deepwater dismantling zone.
• Vegapunk learns that Leviathan has been defeated and its power cut off. Tony taunts him, claiming Eclipse can decipher and improve the ancient technology.
• At the dock, Tony discovers valuable components, including a miniature space-folding generator. Kahn orders the useful technology adapted for Eclipse’s Third-Generation Mecha ahead of a future attack on Mary Geoise.

Character developments and interactions

• Kahn remains calm under pressure and decisively prevents the cannon from firing. He treats Leviathan as a valuable prize and focuses on preparing for the larger conflict.
• Tony demonstrates technical ingenuity by coordinating the capture, then eagerly studies Leviathan and boasts that he can surpass its technology. His call to Vegapunk is openly mocking.
• Vegapunk is shaken by the rapid defeat of the ancient weapon and collapses, confronting the limits of the technology he had trusted.
• Luffy, Ace, and Sabo watch the battle and later inspect Leviathan. Luffy humorously mistakes its glowing cannon for something cooked and wonders whether the machine contains meat; Ace and Sabo correct him and recognize the weapon’s formidable defenses.
• The wider world reacts with disbelief as spies and brokers report that Eclipse has captured the World Government’s enormous trump card.

Significant themes

• Technological rivalry: Eclipse’s engineering and force overcome a weapon built on ancient technology.
• Power used with restraint and purpose: Kahn stops Leviathan’s catastrophic attack while preserving it for study.
• Adaptation and escalation: Eclipse turns an enemy weapon into resources for its own military upgrades, anticipating a larger confrontation.
• Hubris and reversal: Vegapunk’s confidence in Leviathan’s superiority gives way to shock when it is decisively defeated.

Key plot points and events

• Atlas and Pythagoras are stunned that Leviathan’s defenses failed after only a few exchanges. Vegapunk replays the battle and realizes Tony Stark identified a 0.004-second vulnerability in its spatial-fold shield.
• Tony hacks into Punk Records and mocks Vegapunk’s security and his reliance on ancient technology. He reveals that a flaw in Leviathan’s energy circuit caused power to flow backward and the shield to collapse.
• Tony displays advanced blueprints, including a more efficient fusion system that could reduce the energy cost of spatial deflection. Vegapunk becomes absorbed in the designs, recognizing that they solve problems he has struggled with for decades.
• Tony invites Vegapunk to leave the World Government, bring Punk Records, and join him at the Eclipse Armory. The blueprints then vanish before the team can save them.
• When Atlas reports that the Five Elders want Leviathan’s results and another batch of Seraphim, Vegapunk chooses to sever his communication line to Mary Geoise.

Character developments and interactions

• Vegapunk shifts from shock and humiliation to intense fascination with Tony’s work. His scientific curiosity ultimately outweighs his loyalty to the World Government, prompting him to cut off contact.
• Tony Stark establishes intellectual and technological superiority, ridicules Vegapunk’s methods, but also acknowledges his ability and tries to recruit him.
• Atlas and Pythagoras react with alarm to Leviathan’s defeat, help process Tony’s information, and attempt unsuccessfully to preserve the disappearing blueprints.
• Tony’s encounter with Vegapunk is both a confrontation and a recruitment pitch: he undermines Vegapunk’s pride while offering him a chance to pursue greater scientific ambitions.

Key plot points

• Vegapunk decides to sever Egghead’s connections to the World Government, but Shaka warns that a hidden control protocol would detect the disconnection and trigger a Buster Call.
• Tony Stark remotely breaks the protocol, disguises Egghead’s status, and feeds Mary Geoise false reports showing Leviathan attacking Wano. He gives Vegapunk twenty minutes to evacuate.
• Vegapunk orders the satellites to preserve his most important research, including Punk Records, Lineage Factor maps, artificial Devil Fruit data, and Seraphim backups. He dismisses the Government-funded equipment as expendable and activates Egghead’s self-destruct sequence.
• The group races toward an evacuation route as the facility’s weapons archives begin melting and laboratories collapse in flames.
• At Mary Geoise, the Five Elders believe Leviathan is winning in Wano. Their confidence ends when Egghead’s communications and monitoring systems suddenly fail.
• Realizing Vegapunk has defected and may take the Government’s secrets to Eclipse, the Elders order an emergency mobilization. One contacts Sengoku and demands that the Marines prepare for combat.

Character developments and interactions

• Vegapunk moves from frustration to decisive rebellion, openly rejecting the Celestial Dragons and choosing to preserve his work rather than serve their ambitions.
• Shaka acts cautiously, explaining the danger of the backdoor; Atlas, Lilith, and Pythagoras respond to Vegapunk’s orders and help prepare the evacuation.
• Tony Stark demonstrates his superior technical skill by defeating the Government’s security system and creating a convincing deception, while bluntly warning Vegapunk not to miss his chance to escape.
• The Five Elders, initially smug about their apparent victory, become furious and alarmed once Egghead vanishes from their surveillance. They recognize Vegapunk’s defection as a serious threat.

• Knowledge as power: The research the Government wants to control becomes the central prize of the escape.
• Technology and deception: Stark’s hacking turns the World Government’s surveillance against it, buying Vegapunk time.
• The cost of rebellion: Vegapunk sacrifices Egghead’s facilities and risks triggering a military response to escape the Government’s grasp.

Plot points and events

• The Five Elders learn that Dr. Vegapunk has defected to Eclipse, taking the ancient warship Leviathan, Punk Records, the Seraphim control authority, and their original templates. They fear Eclipse will gain an overwhelming technological advantage.
• The Elders order Vegapunk and Egghead Island destroyed before he can evacuate. They reject a conventional fleet as too slow and dangerous, and instead send Admiral Kizaru, whose Glint-Glint Fruit makes him the fastest available Marine.
• Fleet Admiral Sengoku relays the order to Kizaru. Though Kizaru complains about the assignment and lingering injuries from his encounter with Kahn, he obeys and speeds toward Egghead Island.
• The chapter ends with Kizaru racing toward the island as its evacuation begins, setting up an imminent confrontation.

Character developments and interactions

• The Five Elders’ anger reveals how seriously they view Vegapunk’s defection: they prioritize preventing Eclipse from gaining his knowledge over recovering the stolen data.
• Sengoku is troubled by the order and by Eclipse’s rapid expansion, but remains responsible for carrying out the government’s command. His final thoughts show growing fear that the Marines may not withstand the crisis.
• Kizaru maintains his laid-back, complaining manner, but ultimately acts on the order. His mention of Kahn hints that his confidence may be tempered by recent injuries.
• Sengoku and Kizaru’s exchange contrasts Sengoku’s urgency with Kizaru’s casual demeanor.

Significant themes

• The struggle for technological power: Vegapunk’s expertise could combine with Stark’s industrial capacity and shift the balance of power.
• Authoritarian control and desperation: The Elders respond to defection with an order to annihilate the scientist and his island.
• An escalating crisis: Eclipse’s victories and expansion leave the World Government and Marines increasingly on the defensive.

Vegapunk and Atlas tried to escape Egghead Island with the doctor’s research data, but Kizaru destroyed the defenses and cornered them underground. After defeating the Pacifistas, Kizaru aimed a lethal attack at Vegapunk, leaving his fate unresolved.

• Vegapunk and Atlas rushed to the escape submarine with thirty years of research data as Mr. Stark’s pickup ship approached.
• Kizaru destroyed Egghead Island’s defenses and confronted Vegapunk at the underground passage.
• Vegapunk activated three Second-Generation Pacifistas, and Atlas charged Kizaru to buy time for their escape.
• Kizaru evaded the Pacifistas’ lasers and destroyed all three with Yasakani Sacred Jewel, injuring Atlas.
• Kizaru pointed a charged light attack at Vegapunk and prepared to kill him for refusing to work for the World Government.

Kahn and Tony Stark used a spatial portal to rescue Vegapunk and his damaged satellites from Kizaru on Egghead Island. Kizaru was left alone in the wrecked passage as the portal vanished with the scientists and their research.

• Shaka threw himself between Vegapunk and Kizaru, but Kizaru kicked him into an alloy wall and incapacitated him.
• Kizaru fired a laser at Vegapunk, but an orange-gold portal opened and swallowed the beam.
• Tony Stark spoke through the portal and pulled Vegapunk and his metal case toward it with a mechanical arm.
• Tony said JARVIS had marked Atlas and Shaka, and tractor beams hauled both damaged satellites into the portal.
• Kizaru attacked the portal with a Haki-coated Light-Speed Kick, but Kahn stopped him with a Bio-Force Field and reminded him of their past encounter.
• Vegapunk, Atlas, and Shaka escaped as the portal closed, leaving Kizaru to face the loss of Egghead Island's secrets.

Tony and Sabo fought Admiral Kizaru as he tried to destroy Vegapunk’s research, but a mysterious force stopped Kizaru at the portal. The chapter left the source of that power unidentified as it addressed Borsalino.

• Tony and Sabo confronted Kizaru while protecting Vegapunk and the metal case containing his research.
• Kizaru attacked Tony with the Ama no Murakumo Sword, but Sabo blocked it with his Haki-coated pipe and white-gold flames.
• Tony launched Seastone-coated electromagnetic nets, but Kizaru scattered into flecks of light to evade them and reach the case.
• Sabo and Tony tried to intercept Kizaru, but he re-formed beside the portal and aimed a laser at the storage device.
• A powerful presence crossed the portal, made Kizaru’s photons tremble, and dissolved his laser as a calm voice called him Borsalino.

Kahn stopped Kizaru from reaching Vegapunk’s core data by projecting his crushing power through the Space Gate. Kizaru fled, and Tony, Sabo, and Vegapunk carried the data box through the portal to Wano Country.

• Kahn detected Kizaru approaching the Core Data Box and sent his Bio-Force Field through the Space Gate to Egghead Island.
• Kahn’s pressure immobilized Kizaru and disrupted his photon body while Tony and Sabo guarded Vegapunk and the data box.
• Kahn warned Kizaru to back away or die, and Kizaru collapsed to his knees before retreating from the laboratory.
• Kizaru abandoned the World Government’s elimination order and fled, saying he would report the truth to the Five Elders.
• Tony, Sabo, and Vegapunk entered the Space Gate with Punk Records’ core data and returned to Wano Country.

Kizaru staged an injury to retreat from Egghead Island after sensing Kahn's overwhelming power, while Sabo and Tony prepared to take Vegapunk to Wano Country. Vegapunk followed them through the Space Gate, leaving the ruined laboratory behind.

• Kizaru surrendered to the threat from the portal and told Fleet Admiral Sengoku that he had been badly wounded and was retreating.
• Sengoku accused Kizaru of pretending, but Kizaru hung up and fled Egghead Island as a pillar of light.
• Sabo and Tony reassured Vegapunk that it was safe and invited him to return with them to Wano Country.
• Vegapunk wondered what kind of being led Eclipse, then followed Sabo and Tony through the Space Gate.
• The Space Gate vanished after the three entered it, leaving the Egghead Island Laboratory silent.

Vegapunk, Tony, and Sabo escaped Egghead Island through a portal to Wano Country after Vegapunk triggered the island’s destruction. They arrived at the Eclipse Armory, where Vegapunk marveled at its automated workshops before following Tony and Sabo to meet Kahn.

• Tony, Sabo, and Vegapunk evacuated the research crates through a portal while Sabo confirmed that Kizaru and the Marine warships had withdrawn.
• Vegapunk activated Egghead Island’s self-destruct and crossed through the portal with Tony and Sabo.
• The Ancient Power Furnace exploded, causing Egghead Island to collapse and sink beneath the sea.
• Vegapunk, Tony, and Sabo arrived at the underground Eclipse Armory in Wano Country.
• Vegapunk eagerly examined the armory’s automated production lines and machinery.
• Tony told Vegapunk that Kahn was waiting, and Vegapunk followed Tony and Sabo toward the Castle Keep.

Vegapunk marveled at Tony’s Arc Reactor, then saw Tony’s equations overcome the limits of his Seraphim research and agreed to assist him in dismantling the ancient Mechanical Leviathan. As Tony and Vegapunk began planning the work, Kahn appeared above them and watched.

• Vegapunk was astonished by the Arc Reactor’s clean, efficient power and praised its potential to improve the Mother Flame and restore the Ancient Kingdom’s energy grid.
• Tony criticized Vegapunk’s Seraphim designs and gave him equations that could raise their energy conversion efficiency above ninety-two percent.
• Vegapunk recognized the value of Tony’s work and agreed to become his assistant, offering to decode the Mechanical Leviathan’s ancient spatial deflection system.
• Tony and Vegapunk inspected the Mechanical Leviathan and debated how to remove its power core safely, while Sabo watched them work together.
• Kahn appeared on the workshop’s upper walkway and silently scrutinized Tony and Vegapunk.

Kahn forced Vegapunk to join Eclipse and ordered him to develop a spatial deflection shield for Tony's enormous warship within fifteen days. As construction advanced, Sabo reported that the World Government had covered up Egghead Island's sinking and falsely declared Vegapunk dead.

• Kahn confronted Vegapunk and ordered him to combine Punk Records with Tony's production lines to build a pilot spatial deflection shield in fifteen days.
• Vegapunk bowed to Kahn, granted Eclipse full access to Punk Records, and agreed to work for the organization.
• Tony showed Vegapunk the design for a vast seastone-vibranium warship intended to attack Mary Geoise, and JARVIS corrected a flaw in its power system.
• Vegapunk hurried to retrieve an ancient coding dictionary and promised to complete the shield without delay.
• Tony told Kahn that the warship's main keel had been laid in an underground workshop using Wano Country seastone and Pluton Blueprints from Water 7.
• Sabo told Kahn that the Five Elders had concealed Egghead Island's sinking and claimed Vegapunk died in an accidental explosion.

After Vegapunk defected to Wano with his research, the Marines and World Government confronted the loss of Egghead and its technology. Sengoku tried to conceal the news, but Morgans exposed the defection worldwide, while the Five Elders decided to seek Imu’s approval to use Uranus against Wano.

• Sengoku confronted Kizaru over his account of the Egghead mission, while Garp laughed and Akainu accused Kizaru of failing to protect Vegapunk.
• Tsuru reported that Egghead had sunk and Vegapunk had defected to Wano with researchers, satellites, and core research data, leaving the Marines’ science programs crippled.
• The Five Elders recognized that Eclipse could turn Punk Records’ secrets into weapons and agreed to request Imu’s approval to awaken Uranus and destroy Wano.
• Sengoku ordered a news blackout and instructed the Marines to claim Vegapunk had died in a tsunami.
• Morgans released newspapers across Marineford and the Grand Line, publicizing Vegapunk’s defection and Eclipse’s technological gains.

Imu ordered the Five Elders to release monsters sealed away across the world and use them to wear down Kahn after Uranus proved unable to target Wano reliably. Marine forces began carrying out the plan, and the chapter ended as the sealed door to Impel Down’s deepest passage opened and bloodthirsty eyes appeared in the darkness.

• The Five Elders told Imu that Vegapunk had defected to Eclipse and that Uranus lacked the power to destroy Wano while Kahn’s magnetic field disrupted its targeting.
• Imu gave the Five Elders an ancient list and ordered them to summon its imprisoned and sleeping monsters, promising pardons and territories to those who killed Kahn.
• Sengoku received the deployment order and divided the operation among Impel Down, Deserted Island, and Elbaf, assigning Kizaru and other forces to recruit the monsters.
• Magellan and Hannyabal descended to Impel Down’s unmarked sealed level, where Kizaru and the CP0 commander joined them.
• The CP0 commander unlocked the massive seastone door, and several pairs of bloodlust-filled eyes opened in the darkness.

Kizaru and Magellan visited Impel Down’s forbidden prison level to offer Douglas Bullet, Patrick Redfield, Byrnndi World, and other prisoners pardons in exchange for killing Kahn. Bullet, the Red Count, and World accepted the mission and were released under the Five Elders’ control, then headed for a warship bound for the New World.

• Kizaru, Magellan, Hannyabal, and two CP0 agents entered Impel Down’s unrecorded prison level, where Douglas Bullet, Patrick Redfield, and Byrnndi World were chained to pillars.
• Kizaru read the Five Elders’ offer of pardons, freedom, and territories in exchange for traveling to the New World and killing Kahn.
• Bullet erupted with Conqueror’s Haki, knocking out the jailers and cracking the seastone hooks, while Magellan prepared to stop him.
• Patrick Redfield remarked on the World Government’s desperation and expressed interest in Kahn, while World demanded release so he could attack Marine Headquarters and kill Kahn.
• A CP0 agent warned that neurotoxins and tracking devices controlled the prisoners, then unlocked Bullet, Redfield, and World and removed their hooks.
• Kizaru told the three former prisoners that a warship awaited them, and they walked toward the exit.

After their release from Impel Down, Douglas Bullet killed a Marine Rear Admiral and fought Kizaru before the World Government ordered him, Byrnndi World, and the Red Count to target Kahn and Eclipse. The three villains sailed toward the New World, intent on destroying Kahn and pursuing their own violent ambitions.

• Douglas Bullet killed the Rear Admiral who ordered him to board the warship.
• Kizaru attacked Bullet, but Bullet repelled his Light-Speed Kick with a Haki-coated punch.
• Kizaru offered Bullet and Byrnndi World freedom and territory in exchange for killing Kahn and destroying Eclipse.
• Byrnndi World rejected the offer of kingship and threatened to destroy Marine Headquarters and the World Government.
• The Five Elders ordered Bullet, World, and the Red Count to attack Wano Country within half a month and bring back Kahn's head.
• Bullet, World, and the Red Count boarded a warship and departed Impel Down for the New World.

CP0 envoys arrived in Elbaf with treasure and supplies to ask the giants for military aid. After Asgar demonstrated his strength by killing an Ancient Land Tyrannosaur and splitting a distant mountain, he heard the Five Elders wanted Elbaf’s Berserker Legion to fight New World rebels.

• A CP0 delegation sailed to Elbaf under the Five Elders’ orders, carrying food, liquor, gold, and other valuables as a goodwill offering.
• Elbaf’s giant guards allowed the envoys to dock and directed them to the king at the central training arena.
• Asgar killed a charging Ancient Land Tyrannosaur with one Haki-coated axe strike, cleaving through the arena wall and a distant snowy mountain.
• Asgar confronted the CP0 leader, who asked Elbaf to deploy the Berserker Legion against rebel forces in the New World.
• Asgar mocked the World Government for failing to defeat the rebels and questioned whether their strength exceeded the beast he had just slain.

Sengoku appointed Issho and Aramaki as Admirals through the World Military Draft, hoping to bolster the Marines against Eclipse. Issho accepted the role to protect civilians, while Aramaki pledged fanatic loyalty to the Celestial Dragons, deepening Akainu’s anger as the World Government’s God's Army began to take shape.

• Sengoku defended bypassing the usual promotion process because the Marines urgently needed powerful fighters against Eclipse.
• Issho crushed a fleeing pirate ship with gravity, and Aramaki drained the pirates aboard another ship with roots.
• Sengoku persuaded Issho to accept the Admiral's coat by appealing to his desire to protect ordinary people.
• Aramaki accepted the other Admiral's cloak and declared his loyalty to the Celestial Dragons, demanding to be sent to Wano to kill Kahn.
• Akainu condemned the appointments and stormed back into headquarters, while Sengoku recognized that the Marines' internal divisions were worsening.
