Recaps

After studying King’s genetic sample, Mousse and Vegapunk discovered why Lunarians could survive anywhere but concluded that the species could not be saved through cloning or crossbreeding. Their findings inspired Vegapunk to pursue mass-produced environmental energy conversion, but he wanted World Government support, while Mousse doubted the Government would cooperate; Mousse eventually agreed to let Vegapunk try.

• Mousse’s failed attempts to clone King led him to bring Vegapunk into the research.
• Vegapunk found that Lunarians absorbed energy from their surroundings, but their biology made reproduction with other races and viable clones effectively impossible.
• The Lunarian research inspired Vegapunk to consider developing mass-producible devices that drew energy directly from the environment.
• Vegapunk realized that Totto Land lacked the resources to advance the project quickly and proposed seeking investors and scientists, starting with the World Government.
• Mousse argued that the World Government would use the technology to preserve its rule and could not trust Totto Land, but Vegapunk insisted he had no time to wait.
• Mousse stopped trying to dissuade Vegapunk and agreed to let him attempt to secure cooperation.

After the World Government rejected Mousse’s proposal, he told Vegapunk that platinum lead caused Flevance’s White Rot Disease and offered to remove the poison. Vegapunk helped Mousse gain invisibility, and the Five Elders debated cooperating with Totto Land to save Flevance and preserve its revenue.

• The Five Elders rejected Mousse’s proposal, while Vegapunk accelerated clone cultivation in hopes of strengthening trust between Totto Land and the World Government.
• Mousse explained that platinum lead poisoning caused White Rot Disease, and Vegapunk realized Flevance faced disaster.
• Mousse said he could purge platinum lead from patients and their environment, prompting Vegapunk to see a chance to save Flevance and improve relations with Totto Land.
• Vegapunk implanted the Germa 66 Cyborgs’ invisibility ability in Mousse, who found he could hide Amon as well.
• Mousse and Amon spent several days in Flevance undetected before Totto Land informed the World Government.
• The Five Elders debated Flevance’s platinum lead revenue, the possibility of working with Totto Land, and whether to suspend the plan to destroy the kingdom.

Mousse negotiated with the World Government over the Flevance crisis while secretly ensuring the truth about his role would spread. As he treated the poisoned residents, his investigation uncovered how Platinum Lead caused the illness and revealed a possible way to make Giant Medicine more cheaply.

• Mousse accepted the World Government’s demand to take credit for the response, while seeking enough time to treat Flevance’s residents and planning to spread the truth through Director Trafalgar.
• Mousse met Trafalgar Law and introduced himself, while Law’s family grew more convinced of Totto Land’s power.
• Mousse examined the extracted Platinum Lead dust and discovered that cells could engulf the particles, leading him to consider a cheaper method of making Giant Medicine.
• Mousse explained that the residents’ use of Platinum Lead in paints and ceramics had exposed them to the poison, and that basic safety measures could have prevented much of the disaster.
• Doctor Trafalgar believed Mousse’s account of the World Government and royal family’s profiteering, and his words began spreading through Flevance.

Mousse revealed that his aid to Flevance brought him a fortune by having Xuanhuang extract the Platinum Lead pollution, while also securing ties with the Trafalgar family. He planned to keep the Platinum Lead as a strategic resource and recognized Trafalgar Law as a remarkably gifted future surgeon.

• Mousse explained that the World Government and the Flevance royal family each promised him 5 billion Berries for saving the kingdom and concealing the truth.
• Xuanhuang removed the pollution from Flevance and converted it into refined Platinum Lead powder worth an estimated 200 billion Berries.
• Mousse decided not to sell the Platinum Lead immediately because it was a valuable material for ammunition, science, and his family’s firearms businesses.
• Mousse considered buying more Platinum Lead while its price was temporarily low and noted that he could store it for centuries.
• Mousse judged ten-year-old Trafalgar Law to be an exceptional surgeon with outstanding intellect, vitality, and precise hands, and considered him more trustworthy than Hogback.

Mousse left Flevance after inviting Trafalgar Law to join his future crew once Law was older, then traveled to the North Blue to meet Vinsmoke Judge and recruit Germa 66. Judge welcomed him but refused the offer, saying his children had not grown up yet.

• Doctor Trafalgar asked Mousse to wait a few years before taking the ten-year-old Trafalgar Law, and Mousse agreed while inviting Law to become his future ship's doctor.
• Mousse left Flevance and headed for the North Blue after learning Germa 66 was still there.
• Mousse landed on a Germa 66 snail ship and demanded to meet Vinsmoke Judge.
• Judge assumed Vegapunk had joined the BIG Pirates after Mousse mentioned Teacher Beck, and he recognized Mousse's reputation and scientific achievement.
• Judge gave Mousse a warm welcome but firmly refused his recruitment offer, citing that his children were still too young.

Mousse and Vinsmoke Judge negotiated a scientific exchange after Judge rejected making Germa 66 a vassal of Totto Land. They agreed to trade clone-related technologies, while Judge refused to hand over Germa 66’s Cyborg and Battle Suit technology, leaving Mousse to seek another way to obtain it.

• Mousse explained that the World Government would intervene if Germa 66 tried to conquer the North Blue before it had enough strength, and Judge rejected becoming Totto Land’s pawn.
• Judge agreed to exchange scientific achievements with Mousse after realizing Vegapunk had withheld information about Germa 66’s technology.
• Mousse offered Vegapunk’s improved clone soldier technology, which could grow clones to age eighteen in two years, in return for Germa 66’s Personality and Memory Transplant technology.
• Judge finalized the deal but refused to transfer Germa 66’s Cyborg and Battle Suit technology, fearing Big Mom would become impossible to counter if she acquired it.
• Mousse accepted the lesser exchange, while his research skills gave him another path toward learning Germa 66’s technology.

Mousse infiltrated Germa 66 and confronted Judge’s young children, testing their abilities and exposing the emotions they still retained. He overwhelmed the brothers, and Sanji was left crying after his attempt to help was rejected.

• Mousse used his invisibility to enter Germa 66 and found Sanji being bullied by Ichiji, Niji, and Yonji while Reiju hesitated to intervene.
• Mousse struck Yonji with Amon, sending him into Niji and a steel wall; Yonji fainted, and Niji became trapped and injured.
• Ichiji called for guards and mocked Mousse, while Reiju tried to prevent the siblings from attacking him and Sanji decided to join them.
• Niji kicked Sanji down, and Mousse grabbed Niji and swung him into Ichiji, causing Ichiji to faint.

Mousse revealed that his body ignored the Vinsmoke children's Electric Shock and teased them about his resistance. He drew a portable cell-scanning syringe to examine the Germa 66 children and pinned Vinsmoke Ichiji down, preparing to inject him.

• Vinsmoke Ichiji questioned Mousse about his resistance to Electric Shock, and Mousse told him to beg for an answer.
• Vinsmoke Reiju tried to coax Mousse into explaining, but he produced a living-cell analysis syringe and threatened to give her a shot.
• Mousse explained that the device could scan living cells quickly and that he wanted to compare the siblings' modifications.
• Vinsmoke Reiju released toxin while Vinsmoke Ichiji charged Mousse with flame-assisted speed.
• Mousse dodged Ichiji's charge and pinned him to the ground with his superior strength.

Mousse subdued the Vinsmoke children and Germa 66’s soldiers while collecting information on the siblings’ bodies. Vinsmoke Judge realized Mousse could eventually develop Germa’s technology himself and began considering whether to sell it.

• Mousse used his Seastone syringe on Vinsmoke Ichiji, then froze Vinsmoke Reiju when she tried to stop him from injecting Sanji.
• Mousse injected Sanji and scanned his body, while Sanji persuaded Reiju that Mousse did not intend to harm them.
• Germa soldiers arrived, but Mousse froze them all before they could attack.
• Vinsmoke Judge confronted Mousse, who mocked Germa’s family and defended collecting its scientific information.
• Vinsmoke Judge recognized that Mousse might uncover Germa’s cyborg secrets without help and began weighing whether to sell the technology.

Mousse’s earlier release of an improved King’s Fist led to a pirate devastating Marine forces, making Vinsmoke Judge more eager to trade Germa 66’s Cyborg technology. Mousse obtained the technical materials, but found they differed from what he had expected.

• Mousse continued studying the cell data he had scanned, expecting his research to reduce the value of Germa 66’s technology.
• A pirate named Phideas used the King’s Fist to destroy a Navy battleship and attack the Marine G-4 Branch, killing thousands before Kizaru knocked him into the sea.
• Mousse considered how the spread of the King’s Fist could overwhelm Marine defenses and benefit Totto Land, which was easier to protect.
• Vinsmoke Judge agreed to exchange his family’s Cyborg technology so he could strengthen Germa 66 and show goodwill toward the Charlotte Family.
• Mousse obtained the technical materials and discovered that they differed from what he had expected.

Mousse evaluated Vinsmoke Judge’s Cyborg technology and found it less useful to himself than Queen’s imitation, though it could benefit some of his siblings. Studying Judge’s technical documents gave Mousse a breakthrough on the Devil Radar, leaving him intent on seeking the Rumble-Rumble Fruit instead of giving Katakuri a weaker electric ability.

• Mousse learned that Judge’s Cyborg technology could implant different Devil Fruit abilities but had major limits, including weak powers, high costs, and incompatibility with other Devil Fruit abilities.
• Mousse reconsidered Queen’s imitation technology, recognizing the value of stacking abilities such as invisibility and electricity-powered speed.
• Mousse realized Judge’s technology could still help siblings such as Praline, while deciding not to erase the Charlotte children’s emotions to make them train harder.
• Mousse considered replacing Katakuri’s Mochi Mochi Fruit ability with an electric one, but studying Judge’s documents gave him a path toward building the Devil Radar.
• Mousse decided to use the Devil Radar to search for the Rumble-Rumble Fruit and make Katakuri wait rather than settle for a weaker electric ability.

Charlotte Mousse explained why Sanji had greater potential than his brothers and suspected Vinsmoke Judge had altered his sons’ loyalty after betrayal within Germa 66. He offered Sanji a chance to leave for Totto Land, but the crying child still clung to hope that his father wanted him.

• Mousse argued that the Vinsmoke brothers’ altered bloodlines and lost emotions limited their potential, while Sanji could still awaken Haki and benefit from his training.
• Judge challenged Mousse to take Sanji, and Mousse realized Judge might still care about his youngest son despite his harsh treatment.
• Mousse speculated that Judge’s father and elder brother had betrayed and disfigured him, prompting him to secure his children’s loyalty through science.
• Mousse decided to ask Sanji what he wanted before taking him, mindful of his past experience with Nico Robin.
• Sanji cried when he thought his father no longer wanted him, and Mousse offered him safety, respect for cooking, and training in Totto Land.

Mousse reconsidered how to cooperate with Germa 66 and began outsourcing non-secret research rather than sharing core technology. After Dr. Tsukimi joined Totto Land, Mousse learned more about the Moon People and the history of their settlement on Machine Island.

• Mousse left young Sanji behind, while his technology exchange with Germa 66 continued to benefit both sides.
• Mousse rejected selling Giant Medicine cheaply and decided to pay Germa 66 to handle research projects that did not involve Totto Land's core secrets.
• Dr. Tsukimi arrived in Totto Land and joined its research team, prompting Mousse to reconsider whether robots could reach the moon by balloon.
• Mousse learned that Dr. Tsukimi and Vegapunk descended from the Moon People, whose Machine Island settlement had a long tradition of scientific research.
• Mousse learned that Machine Island's technology had regressed because the lunar immigrants lacked people and resources, and because the World Government suppressed technological progress after the upheaval eight hundred years earlier.

Mousse prepared for an expedition to the moon, equipping himself and the scientists with protective suits before exploring the ruins of Moon Civilization. The expedition uncovered advanced but disappointing technology and suggested that lunar civilization had been less powerful than its inventions implied.

• Mousse concluded that his abilities might let him rival Vegapunk and decided to explore the moon while the World Government’s deception was exposed.
• Mousse built a space-capable Battle Suit and prepared spacesuits and oxygen equipment for the scientists.
• Mousse and Amon reached the moon, where Mousse used his oxygen tank and helmet after the thin atmosphere slowed his thinking.
• The scientists found Moon Civilization’s ruins and recovered intelligent robots, which Mousse judged too weak and costly to serve effectively as soldiers.
• Mousse realized that the Moon People had abandoned the lunar city over an energy shortage that a Devil Fruit user could easily solve, suggesting their civilization had been technologically advanced but not especially powerful.

Mousse gained electrical abilities that let him travel almost instantaneously across conductive media, making him a formidable strategic threat. After Fisher Tiger escaped Mary Geoise and exposed a weakness in the Celestial Dragons’ device, Mousse grew bolder but chose to stay behind the scenes, wary of their mysterious national treasure.

• Mousse used Vegapunk’s help to develop the Devil Radar in secret while the World Government stalled its promised payments and research support.
• Fisher Tiger broke free from slavery in Mary Geoise, rescued thousands, and escaped into the sea after discovering that distance and seawater could disable his bomb collar.
• Mousse concluded that the Celestial Dragons had not used their national treasure because it carried great costs or risks, then recognized that his existing travel methods were too slow for distant emergencies.
• Mousse shifted his research toward electrical abilities and, with Vegapunk’s assistance, implanted himself with electricity the following year.
• Mousse tested his new power and found that he could cross conductive media at nearly light speed, making him exceptionally difficult to hit and a threat even to Kizaru.
• Mousse decided not to confront the World Government or capture Kizaru, choosing instead to avoid provoking a desperate response and to keep draining its resources through schemes.

Mousse developed the Devil Radar, visited Jaguar D. Saul on Little Garden, and used the Scroll Amon to help him master the Hero's Spear. The chapter left Mousse fighting the giants Dorry and Brogy, relying on his extraordinary speed rather than Teleportation.

• Mousse learned that Queen's method allowed each special ability to be implanted in only one person, so he kept the Electric ability for himself and placed a Fish-Man informant aboard Fisher Tiger's ship.
• Mousse learned that Monkey D. Dragon had founded the Revolutionary Army, but decided not to approach him yet and focused on other urgent work.
• Mousse made a breakthrough on the Devil Radar, then traveled to Little Garden to visit Jaguar D. Saul, who had become sworn brothers with Dorry and Brogy.
• Mousse used the Scroll Amon to make Jaguar D. Saul collapse, explaining that he would wake within a day and be able to master the Hero's Spear.
• Brogy attacked Mousse, but Dorry stopped him long enough to hear Mousse's explanation; Mousse agreed to fight without Teleportation.
• Mousse rapidly stomped the ground to accelerate and effortlessly dodged Brogy's first probing strike.

Mousse tested his strength against Brogy, then won the trust of Dorry and Brogy by sharing liquor with them. From their stories, he learned that Elbaf’s reputation rested on the Giant race’s innate power and the Elbaf Spear, a technique that could be combined by multiple users.

• Mousse used his speed to evade Brogy and kicked the giant’s wrist, but Brogy barely reacted.
• Mousse used a 2.5x Strike to pierce Brogy’s palm, then ended the fight after judging the gap between their strength.
• Mousse brought out dozens of tons of strong liquor, and Dorry and Brogy eagerly drank with him.
• After getting the former captains drunk, Mousse learned that Elbaf had once killed a Marine Admiral and that the Giant Soldier Pirates had lost a civil war there.
• Mousse realized that multiple giants could combine their strength to unleash the Elbaf Spear.

Brogy and Dorry explained Elbaf’s history, the Dwarf King’s legacy, and the rules for choosing its ruler to Mousse. Mousse learned that Prince Loki could inherit the throne, but suspected the royal family’s supposedly fair succession system favored its own candidates.

• Brogy and Dorry described how the Dwarf King united Elbaf, spared defeated rivals by sending them to sea, and taught the Giants the Elbaf Spear.
• They recounted how the Giant Soldier Pirates troubled the World Government and how its fleet was devastated when it attacked Elbaf.
• Brogy wept as he spoke of the Dwarf King’s kindness, while Mousse privately doubted the story’s idealized portrayal of him.
• Mousse told the brothers that Charlemagne had a son, Prince Loki, and they were encouraged that the royal line had an heir.
• Dorry and Brogy explained that Elbaf’s rulers had to defeat challengers to claim the throne, and Mousse learned that royal and outsider candidates fought separate contests before their winners faced off.

Mousse examined Elbaf’s warrior hierarchy and questioned how its royal family maintained its strength, then helped Jaguar D. Saul master the Elbaf Spear. The chapter ended with Mousse reconsidering why Dorry and Brogy had become captains of the Giant Soldier Pirates and what their departure meant.

• Mousse learned that mastering the Elbaf Spear made a Giant a Warrior of Elbaf and eligible to challenge the heir, and he considered how few Giants reached that level.
• Mousse questioned how the royal family kept producing rulers strong enough to dominate Elbaf’s challengers.
• Mousse found that Jaguar D. Saul had grown into a barbarian hero in the story world and released his soul, allowing Saul to use the Elbaf Spear: Hero’s Spear.
• Mousse asked why Dorry and Brogy had become captains when more than ten Warriors were stronger than them.
• Dorry and Brogy explained that they had sailed out of curiosity about the world, unlike crew members who had been forced to leave, prompting Mousse to reconsider the Giant Soldier Pirates’ search for them.

Mousse sent Dorry, Brogy, and the other Giants to Enies Lobby to retrieve two men, while deciding to let them investigate the truth about Charlotte Linlin before he visited Elbaf. He then traveled to Water 7 to meet Fish-Man Tom and see whether he could learn about Pluton’s blueprints.

• Mousse reflected on why the strength gap between teammates tended to persist and wondered what opportunities for growth Giants had in Elbaf.
• Mousse enlarged Amon’s scroll form into a huge entrance and brought the three Giants into Book World.
• Mousse told Dorry and Brogy about Charlotte Linlin’s history with the Giants, and they judged Yoruru’s defeat and Yaruru’s attempted ambush as potentially dishonorable while reserving judgment until they heard Elbaf’s account.
• Mousse sent the three Giants to Enies Lobby to retrieve two men, planning to publicize their presence so the World Government would not resist their release.
• Mousse traveled to Water 7 to visit Fish-Man Tom, who had previously rejected an invitation from Charlotte Linlin, and hoped to see Pluton’s blueprints.

Mousse examined Pluton’s blueprints and concluded that the battleship was prohibitively expensive, vulnerable to powerful individuals, and of little practical value. He found the explosive shells potentially useful for improving firearms, leaving with one possible benefit from his investigation.

• Mousse used his invisibility and Soul Capture to obtain information from Fish-Man Tom and find the Pluton blueprints.
• Mousse calculated that building Pluton would cost at least two trillion Berries and could destabilize the World Government’s finances.
• Mousse identified Pluton’s weaknesses: its heavy cannons struggled to target fast individuals, and its defenses could not withstand powerful attacks.
• Mousse considered Sea King’s vulnerability and wondered whether the real Pluton had a Ship Spirit that could repair damage.
• Mousse found little useful in Pluton’s materials or design but considered adapting its powerful explosives into firearm propellant.

Mousse assessed the Sea Train’s high costs and limited usefulness in the Pirate World, then explained how Katakuri’s new Rumble-Rumble Fruit would make him far more dangerous. The chapter ended with Katakuri’s lightning ability preserving the full properties of his Demon Halberd when he elementalized it.

• Mousse concluded that the Sea Train was costly to build and maintain, and that air travel for passengers and water transport for cargo would be more competitive if airplanes could be mass-produced.
• Mousse used the improved Devil Radar to find the Rumble-Rumble Fruit for Katakuri.
• Mousse reasoned that the fruit’s speed and boost to Observation Haki mattered more than its flashy lightning attacks, whose destructive power was limited compared with other Devil Fruit abilities.
• Katakuri tested the fruit and found that its Electric Shock could paralyze enemies and force them to expend Armament Haki to defend themselves.
• Katakuri discovered that he could elementalize his Demon Halberd and restore it without losing its original qualities.

Mousse assessed the immense power Katakuri gained from the Rumble-Rumble Fruit and publicized his new SS-rank abilities to deter the World Government. The World Government continued to ignore Totto Land’s growing power, while the Charlotte Family’s leverage and freedom to act increased.

• Mousse devised Triple Strike, combining lightning, the Demon Halberd, and Haki into a lethal sequence for Katakuri.
• Mousse concluded that Katakuri could become even stronger after awakening the Rumble-Rumble Fruit and could threaten the World Government, though Katakuri had no ambition to challenge it.
• Mousse updated Katakuri’s profile in the World Economic News Paper, publicly rating him SS-rank and revealing his new abilities to maximize deterrence.
• The World Government pretended not to notice Totto Land’s expansion, even after Amon enlarged its islands and dug earth and stone from the Red Line.
• The Charlotte Family’s strength and Katakuri’s speed left the World Government increasingly unable to threaten them, even with the Celestial Dragons’ mysterious national treasure.

The World Government failed to uncover Totto Land’s Devil Fruit removal method as Mousse strengthened its counterintelligence network. After awakening the Rumble-Rumble Fruit, Katakuri gained vast Observation Haki and powerful electromagnetic techniques, earning the name “Thunder God” and making Totto Land’s enemies wary.

• The Five Elders tolerated Katakuri while sending more spies to investigate Totto Land and its Devil Fruit removal method, but Mousse’s intelligence network turned captured CP0 agents into Homies and further improved its defenses.
• Stussy felt fortunate she had switched sides after Totto Land’s counterintelligence work left CP0 heavily infiltrated.
• In Marineford Era 1511, Katakuri awakened the Rumble-Rumble Fruit less than six months after eating it and gained control over electromagnetic waves.
• Katakuri expanded his Observation Haki to cover the Totland sea region, maintained it passively, and learned to move as electromagnetic waves.
• Katakuri developed radar-assisted lightning strikes and a microwave weapon, while finding little use for the electromagnetic cannon.
• After Katakuri defeated several rising pirates, Mousse analyzed his abilities in the World Economic News Paper, and Shanks kept his distance from Totto Land as Katakuri became known as the “Thunder God.”

Mousse split from Totto Land’s financial and intelligence departments after Katakuri stopped him from issuing Soul Coins, then built the ground-effect ship Aurora Goddess for his crew. He traveled to East Blue to measure the world’s constants and prevent Kuina’s death.

• Mousse planned to issue Soul Coins backed by Sky Island gold, but Katakuri halted the plan to protect the Charlotte Family from retaliation.
• Mousse transferred control of the financial and intelligence departments and recruited younger siblings, while Perospero persuaded him to remain involved in research.
• Mousse postponed setting out on his own while Trafalgar Law learned to use the Op-Op Fruit and the crew’s new flagship was built.
• Dr. Tsukimi supervised construction of the Aurora Goddess, a fast ground-effect ship that could transform into a submarine to avoid huge waves.
• Mousse traveled to East Blue to measure the world’s constants and prevent Kuina’s death.
