Chapter Summaries

Roy and Dr. Gracia successfully tested a subject who could use three Devil Fruit abilities at once, though doing so consumed energy at triple the normal rate. Gracia refused to begin transplant surgeries until further tests verified the result, and Roy agreed to wait at least three months.

• Roy had the test subject eat the Smooth-Smooth Fruit after confirming that using two abilities at once greatly increased energy consumption.
• Gracia confirmed that the subject’s genetic sequence and vital signs remained stable after eating a third Devil Fruit.
• Roy commanded the subject to transform into an orange cat, change fur color, and use the Smooth-Smooth Fruit’s ability simultaneously.
• Gracia measured triple energy consumption but found it remained within controllable limits.
• Roy asked when the core members could undergo transplant surgery, but Gracia said he needed to observe Test Subject No. 7 for at least three months and conduct more tests.
• Roy accepted Gracia’s caution and agreed to wait.

Roy showed Hachinosu’s core members a test subject who could use three Devil Fruit abilities, confirming that Dr. Gracia’s experiment had succeeded. The group learned that transplants needed at least three months of further testing, and Roy told them to plan their fruit combinations while they waited.

• Roy brought Test Subject No. 7 to the training ground and ordered him to transform, revealing his Cat-Cat Fruit, Color Fruit, and Smooth-Smooth Fruit abilities.
• Bullet and Hawk Eyes examined the test subject as Roy explained that Dr. Gracia’s experiment could replicate Blackbeard’s special constitution.
• Bullet, Enel, and other core members rushed to the training ground and asked when they could receive transplants.
• Roy warned that Dr. Gracia needed at least three months of observation and comparative experiments before the dangerous transplant surgeries could begin.
• Roy told everyone to choose compatible Devil Fruit abilities and prepare a combination plan within three months, prompting them to consider their options.

Dr. Gracia’s three-month tests confirmed that Subject No. 7 could safely sustain multiple Devil Fruit abilities, though Logia combinations showed slight genetic fluctuations and simultaneous abilities multiplied stamina use. Roy began scheduling heart transplants for Hachinosu’s core members but hesitated over the surgery and learned there was no way to implant the cloned hearts without opening the chest.

• Dr. Gracia found no genetic collapse in Subject No. 7 and confirmed that combinations of two Zoan or two Paramecia fruits caused no problems, while Logia combinations produced slight fluctuations.
• Dr. Gracia reported that using multiple abilities multiplied stamina consumption, and Roy arranged a gradual transplant schedule for Hachinosu’s fighters.
• Roy reviewed the test results and asked Stella to summon Dr. Gracia because he had concerns about the heart transplant.
• Roy asked whether the cloned hearts could be implanted without opening the chest, and Gracia said surgery was the only method and carried almost no risk.
• Roy accepted Gracia’s explanation but remained unsettled by the thought of having his chest opened and an organ placed inside.

Roy searched for an alternative to undergoing heart surgery and realized Trafalgar Law's Op-Op Fruit could let him transplant the cloned hearts without an operation on the table. As Tesoro reported the Supernovas' growing trouble in the New World, Roy called Law and asked him to return to Hachinosu.

• Gracia told Roy that the cloned hearts were ready but would only keep for a month, leaving Roy to consider his options for surgery.
• Tesoro reported that Kid, Apoo, Hawkins, and Capone Bege had caused trouble across the New World and offered to send men to stop them.
• Roy spotted Trafalgar Law's name in the report and realized Law's Op-Op Fruit could perform the heart transplant.
• Roy called Law near Punk Hazard and asked him to return to Hachinosu, and Law agreed without asking why.
• Roy told Tesoro to handle the Supernovas as he saw fit while he relaxed, pleased that he might avoid an operation himself.

Roy prepared to upgrade Hachinosu’s core fighters by arranging heart transplants and collecting information about compatible Devil Fruits. Meanwhile, Law planned to attack Doflamingo’s secret laboratory on Punk Hazard, and a Den Den Mushi began ringing as he finalized the plan.

• Roy told Gracia that Trafalgar Law would perform the heart operation and ordered the first cloned hearts prepared for careful quality checks.
• Roy asked Stella to compile the core members’ abilities, fighting styles, and potentially compatible Devil Fruits within three days.
• Law reviewed intelligence about Doflamingo’s secret experiments on Punk Hazard and reflected on his history with Doflamingo and Rosinante.
• Law told Bepo and Penguin that they would attack the laboratory in three days through a drainage outlet during a patrol change.
• A Den Den Mushi began ringing as Law planned the attack.

Roy summoned Law back to Hachinosu because he needed the Op-Op Fruit’s ability, forcing Law to postpone his plan to attack Punk Hazard. Law and the Heart Pirates arrived at Hachinosu, where he prepared to learn why Roy had called him.

• Roy contacted Law near Punk Hazard and ordered him to return to Hachinosu for a task requiring the Op-Op Fruit’s ability.
• Law told the Heart Pirates to turn their submarine around, and Bepo regretted abandoning their planned attack on Punk Hazard.
• Law reflected on Doflamingo’s increased strength and his own chances of defeating him.
• Law surfaced near Hachinosu and directed the submarine through the southern channel as a guide boat approached.
• A Hachinosu guide boat welcomed Law, and he saw the orderly network of ships around the expanded island.

Law returned to Hachinosu and learned that Roy and Dr. Gracia had succeeded in preparing people to host multiple Devil Fruit abilities. He agreed to perform heart transplants with his Op-Op Fruit and requested a complete surgical manual before beginning.

• Bepo and the Heart Pirates arrived at Hachinosu, where Stella welcomed Law and directed him to Roy's laboratory.
• Law saw the laboratory's cloned organs and research data before Roy explained that three fruits had been successfully tested on seven subjects.
• Roy revealed that Blackbeard's gene sequence could let people accommodate multiple hearts, and Dr. Gracia asked Law to use his Op-Op Fruit for the transplants.
• Law agreed to perform the surgery and learned that about a dozen core members, including Bullet, Mihawk, Tesoro, and Crocodile, were scheduled for the first batch.
• Law asked Dr. Gracia for the transplant procedures and a complete surgical manual so he could prepare.

Roy and Law prepared Hachinosu’s core members for three-heart transplants after completing Blackbeard gene insertions. Roy volunteered to undergo the first operation, declaring that the procedure would help Hachinosu surpass its rivals.

• Law explained that he could replace two hearts and reconstruct the circulatory system in half an hour, and Roy agreed to go first.
• Gracia reported that every core member had received Blackbeard’s gene sequence with a fusion rate above 99.9 percent, and he revealed that the cloned hearts were ready.
• Law warned that the operation required complete trust and relaxation because any involuntary rejection could disrupt the blood vessel connections.
• Bullet, Tesoro, and Crocodile volunteered to be the first test subject, but Roy stopped them and chose to undergo the transplant himself.
• Roy told the gathered fighters to watch as he began the operation, and his Conqueror’s Haki erupted through the laboratory.

Roy underwent surgery to receive two cloned hearts, giving him a stable three-heart circulatory system and two additional containers for Devil Fruit powers. Law then operated on the other core members of Hachinosu and completed a transplant on himself.

• Roy insisted on undergoing the heart transplant first, and Law began the operation as the others watched.
• Law implanted two cloned hearts beside Roy’s original heart and restructured the circulatory system while Roy controlled his heartbeat.
• The operation succeeded, and Roy felt his strength, endurance, and capacity to hold Devil Fruit powers increase.
• Bullet volunteered to go next, and Law performed heart transplants on Hachinosu’s core members over the next few hours.
• Law completed a heart transplant on himself.

Roy distributed the Devil Fruits from Hachinosu’s treasury, guiding his crew as they chose powers suited to their fighting styles. Bullet took the Combine-Combine and More-More Fruits, and several other crew members claimed their chosen fruits as the feast continued.

• Roy opened his storage space and presented the Devil Fruits to the gathered crew, then told Bullet to choose first.
• Bullet took the Combine-Combine Fruit, and Roy urged him to take the More-More Fruit as well so he could amplify his giant combined White Tiger form.
• Tesoro took the Gold-Gold Fruit, and Red Count Redfield chose the Blood-Blood Fruit to control his enemies’ blood and seek revenge on the World Government.
• Savi picked the Repel-Repel Fruit to strengthen his attacks and defense, while Kyros took the Mythical Zoan Fruit of the Onyudo Model and pledged his sword to Roy.
• Van Augur claimed the Door-Door Fruit and explained that its portals would let him fire from unexpected locations.

Roy distributed powerful Devil Fruits among Hachinosu’s fighters and instructed those without a suitable match to hunt for more abilities. The meeting ended with a ban on eating a third fruit for now, as Roy left open the possibility of giving everyone a Mythical Zoan.

• Bar took the Barrier-Barrier Fruit, while Pea took the Mushroom-Mushroom Fruit and the Hobby-Hobby Fruit on Roy’s advice.
• Roy gave Burgess the Tremor-Tremor Fruit and urged him to combine it with his Strong-Strong Fruit.
• Roy gave Kyros the Float-Float Fruit and told him to become Hachinosu’s aerial fortress.
• Crocodile, Moria, Lucci, and others declined the remaining fruits because they did not suit their abilities, so Roy told them to hunt Devil Fruit Users and bring back the powers they wanted.
• Roy stopped Bullet from eating his fruits immediately and set the training ground for the morning after tomorrow.
• Roy adjourned the meeting after forbidding anyone without a Mythical Zoan from eating a third fruit for now.

After the meeting, Roy ate the Soul-Soul Fruit and discovered that it greatly expanded his spiritual power and perception. He successfully divided his attention into four simultaneous tasks, opening new possibilities for combining the fruit with his Telekinesis Fruit.

• After the meeting, Bullet carried two fruits while Tesoro, Jesus Burgess, Savi, and Kyros examined the fruits they had received.
• Kyros wondered whether eating the Float-Float Fruit could let him reach heights like Golden Lion Shiki, and Roy encouraged him to use its power in his own way.
• Roy ate the Soul-Soul Fruit, whose power took root in his second heart without conflicting with the Telekinesis Fruit in his original heart.
• Roy’s perception expanded across Hachinosu and into the surrounding sea, allowing him to sense people, creatures, and their emotions.
• Roy mastered the Soul-Soul Fruit’s abilities and divided his spiritual power into four parts to maintain island-wide Observation Haki, shape a barrier, test Telekinesis techniques, and use his awakened domain at once.

Roy completed his Soul-Soul Fruit test, then ate the Dark-Dark Fruit. Several days later, his crew tested their newly gained powers at Hachinosu, and Roy arrived as Bullet prepared to unleash his full strength.

• Roy fused his divided souls, felt his mental power triple and his Telekinesis-Telekinesis Fruit advance, then ate the Dark-Dark Fruit.
• Tesoro demonstrated Lightning Metallurgy by turning a golden spike into electrically charged needles, while Bar reinforced the training ground's barrier.
• Burgess used the Tremor-Tremor Fruit to split the sea and expose a deep trench.
• Savi uprooted a massive boulder and used Repulsive Force: Limit Blast to carve a huge crater into the training ground.
• Roy praised Savi's increased close-combat strength, then saw Bullet unleash his White Tiger Model and prepare to test his power.

Bullet demonstrated the immense power of combining his Devil Fruits, but Roy stopped his attack by sealing Bullet’s White Tiger Fruit power. Watching them, Dracule Mihawk recognized a gap in his own abilities and left to seek a way to grow stronger.

• Bullet combined his White Tiger, Combine-Combine, and More-More Fruit powers to grow into a gigantic beast and unleash a devastating punch at Roy.
• Roy tried to turn Bullet’s beast into a Homie, then used the Dark-Dark Fruit and Telekinesis to bind Bullet and seal his White Tiger Fruit power, causing the giant form to collapse.
• Roy gathered the falling inorganic matter, released Bullet, and praised his combination of abilities as the two discussed their powers.
• Dracule Mihawk realized that swordsmanship and Haki alone seemed insufficient beside Roy and Bullet’s combined powers, then headed to the intelligence room with Black Blade Yoru.

Roy left Hachinosu with Law and the Heart Pirates, heading for Punk Hazard to pursue several goals, including finding Momonosuke and Vegapunk’s replicated Azure Dragon fruit. He also intended to set Luffy on the path to awakening, while Law considered striking at Doflamingo’s SMILE operation.

• After Bullet’s enormous transformation impressed everyone, Savi and the other Hachinosu officers crowded the intelligence room to search for Devil Fruits suited to their abilities.
• Law prepared to leave Hachinosu with the Heart Pirates, whose crew had grown stronger after Bloodline Transplantation, and Roy joined them.
• Roy secretly planned to visit Punk Hazard to find Momonosuke and the replicated Fish-Fish Fruit, Model: Azure Dragon, and to help bring about Luffy’s awakening.
• During three days beneath the sea, Law told Roy that Doflamingo’s Punk Hazard facility was developing Artificial Devil Fruits for Kaido.
• Roy pointed out that destroying the factory would hurt Doflamingo, and Law recognized Roy’s larger, chess-like plans.

Roy arrived at Punk Hazard and found Momonosuke hiding in the abandoned laboratory, where the hungry child was about to eat a strange fruit. Roy stopped him and took the fruit, while Momonosuke recognized him as one of the men present during the destruction of Kuri.

• Roy flew to Punk Hazard after telling Law to follow their original plan and handle his own business.
• Roy used Observation Haki to locate a faint life sign in an abandoned laboratory near the island's center.
• Momonosuke recalled being sent twenty years into the future and waking alone amid the ruins after Kaido destroyed Kuri.
• Momonosuke broke the glass cover around a strange pink fruit and tried to eat it because he was starving.
• Roy immobilized Momonosuke with Telekinesis, entered the laboratory, and took the fruit from him.
• Momonosuke recognized Roy from the day his father was executed and trembled in fear as Roy told him the fruit was not food.

Roy killed Momonosuke and took Vegapunk's replicated Azure Dragon fruit, then watched the Straw Hat Pirates arrive at Punk Hazard. He planned to use Luffy's Nika awakening against Imu while preparing to strike from the shadows.

• Roy took the Pink Dragon Fruit from Momonosuke and cut off the boy's head with a blade of space.
• Roy put the fruit in his storage bag and decided that the Kozuki Family bloodline ended with Momonosuke, while Kin'emon could still help lead Luffy toward Kaido.
• Roy reasoned that Luffy's Nika fruit could be essential to defeating Imu and planned for Luffy to draw Imu's attention while Roy prepared a secret attack.
• Roy hid behind a telekinetic barrier atop an abandoned cooling tower and watched the Straw Hat Pirates arrive on Punk Hazard.
• Luffy ran across the ice toward the island, followed by Zoro, Nami, Usopp, and Sanji.

Luffy rescued the frozen Kin'emon while Law asked the Straw Hat Pirates to help him take down Doflamingo. Luffy agreed, and Vergo appeared before the new alliance could move forward.

• Luffy found Kin'emon frozen in the ice and carried him toward somewhere warm.
• Law and Bepo fought their way through the facility toward Caesar while Roy observed them.
• Luffy and Law met in a corridor, and Law proposed an alliance against Doflamingo.
• Luffy accepted Law's proposal, and the Straw Hat Pirates agreed to join forces against Doflamingo.
• Vergo confronted Law and called him a traitor.

Law defeated Vergo and captured Caesar while Luffy and his crew rescued the children and destroyed the research base and SMILE factory on Punk Hazard. After the Straw Hats and Heart Pirates departed, Roy told Kaido that Luffy’s Gum-Gum Fruit was actually the Mythical Zoan Human-Human Fruit, Model: Nika, leaving Kaido stunned and asking whether Roy was certain.

• Law used ROOM to cut Vergo apart, then located Caesar and separated his limbs before Caesar could escape.
• Law sent Luffy, Zoro, and Sanji to rescue the children while he took charge of Caesar.
• Luffy found the imprisoned children, punched Caesar, and ordered Chopper to treat them as the crew freed them and destroyed the research base.
• Law handcuffed Caesar, Bepo carried him away, and Franky destroyed the SMILE factory’s poison gas pipes in an explosion.
• Luffy and Law agreed to continue their fight at Doflamingo’s stronghold, while Roy watched unseen and then contacted Kaido.
• Roy told Kaido that Luffy’s fruit was the Human-Human Fruit, Model: Nika, and Kaido asked if he was sure.

Roy told Kaido that Luffy’s Nika fruit needed to awaken and persuaded him to spare Luffy while pushing him to his limits in Wano. Afterward, Aokiji confronted Roy about his ambitions, and Roy openly declared that he intended to overthrow the World Government.

• Roy explained to Kaido the Nika fruit’s power and warned that Luffy and Law had destroyed Doflamingo’s artificial Devil Fruit base.
• Roy asked Kaido to nearly kill Luffy in Wano without finishing him, so the Nika fruit could awaken and draw the World Government’s attention; Kaido agreed.
• Roy invited Kaido to bring his core members to Hachinosu to see the giant beast that had caused a commotion there.
• Aokiji confronted Roy on Punk Hazard and questioned his actions and plans.
• Roy told Aokiji he wanted to overthrow the World Government and establish an era where strength and ability determined who rose to power.
• Aokiji left without joining Roy, heading toward a younger Marine being beaten by Doflamingo.
