Raid on Onigashima

The Raid on Onigashima was a battle that took place on the island of Onigashima in Wano Country during that year's Fire Festival. The invading forces were led by the Ninja-Pirate-Mink-Samurai Alliance, with the objective of defeating the Beasts Pirates, led by Kaidou of the Four Emperors and his allies, including Shogun Kurozumi Orochi and recent ally, fellow Emperor Big Mom.

They succeeded in their goal after many epic battles and with their victory Wano was finally free from 20 years of tyranny and ruined Kaidou's New Onigashima Project thanks to one of the alliance's main leaders, Monkey D. Luffy.

The Beginning of the Great Battle
The Ninja-Pirate-Mink-Samurai Alliance had successfully infiltrated Onigashima despite a few hiccups and even though they snuck into the Beasts Pirates' stronghold the Skull Dome by using disguises, it was not long until a full all-out battle had begun. After Kurozumi Kanjuro was exposed as the spy, Kiku asked him if there was any real companionship from their time together; Kanjuro took what she said as a complement to his acting skills, showing he had no remorse in betraying the Scabbards. This hurt Kiku even more as she fights Kanjuro. The rest of the Scabbards join in and knocked him out. Monkey D. Luffy did not go into battle just yet, as he felt it was not his place to strike the first blow. After 20 years of waiting, the loyal retainers of Kozuki Oden attacked Kaidou of the Four Emperors with all their strength to avenge their master's death and help make his dream of opening Wano's borders a reality, marking the start of the battle.

All the samurai present on the Live Floor were awestruck by Straw Hat Pirates as they showed off their extreme battle prowess by defeated a large portion of the Beasts Pirates's forces with relative ease. Then as the Straw Hats stood united against their foes, Luffy the captain of this motley crew confidently proclaimed that he would be the one to defeat Kaidou. X Drake decided to lend his aid to the alliance despite some of the members being suspicious of him. The All-Star Queen started infecting members of the alliance with his latest artificial virus Ice Oni and gave the antidote to Scratchmen Apoo for safe keeping. However, the Longarm was swiftly defeated by Roronoa Zoro who then retrieved the antidote and gave it to Tony Tony Chopper so it could be mass produced and distributed to everyone.

Kaidou's fellow Emperor Big Mom was reunited with her son Charlotte Perospero who is also an officer of her crew. She stated to her first-born offspring that joining forces with Kaidou was her idea, so Perospero reluctantly accepted her decision. Just as Perospero was about to use one of his candy arrows to kill Marco, the former 1st Division Commander of the Whitebeard Pirates who was held captive by his mother, he was attacked by the Minks named Carrot and Wanda in their Sulong forms and Marco was freed. After which Perospero promptly defeated the two female warriors, while Big Mom rendezvoused with Kaidou.

Glimmers of Hope
Yamato, the son of Kaidou who wished to see the end his father's regime over Wano, met Luffy got and the Straw Hat captain to listen to him. Upon getting Luffy's attention Yamato revealed that he is both a great admirer of Oden and a good friend of the late Portgas D. Ace. After hearing what Yamato had to say Luffy removed the exploding handcuffs from Yamato's wrists that preventing him from leaving the island. The Scabbards fought valiantly on the roof of the Skull Dome, but the samurai ultimately fell before Kaidou's superior might, so, their leader Kin'emon begged Luffy to carry the weight of 20 years of Wano's suffering and defeat Kaidou in their stead, which the Luffy agreed to without hesitation. To the surprise of both Kaidou and Big Mom, Luffy's attack actually did sufficient harm to the Governor-General of the Beasts Pirates and to their anger Luffy once again declared he would be the next Pirate King.

Yamato began helping the alliance by helping Shinobu and Oden's son Kozuki Momonosuke escaping enemy forces. After they found a place to hide and rest for a while Yamato gave Momonosuke his father Oden's journal which documented his travels with the Whitebeard and Roger Pirates, told him and Shinobu his backstory and about his desire to join the Straw Hat Pirates. Despite being infected by Ice Oni, the former yakuza boss Hyogoro defeated all the members of the Orochi Oniwabanshu and the Mimawarigumi, being cured shortly afterwards by Chopper. Queen's callous sacrifice of their lives and Chopper's benevolence in saving them from Ice Oni caused many of the Waiters and Pleasures of the Beasts Pirates to switch sides, giving the alliance some much-needed support.

Though they landed a few hits and caused some significant damage, Luffy, Zoro, Trafalgar Law, Eustass Kid and Killer realized that Kaidou and Big Mom were too powerful together and their only chance at winning was if they could separate the two, so they disarmed Big Mom of her special Homies and threw her off the roof. Napoleon and Prometheus manage to save Big Mom from falling into the sea, and she returned to the Skull Dome to hunt down her enemies for revenge. Big Mom then created a new special Homie named Hera to replace Zeus because she was tired of his constant failures lately.

Fighting the Tobiroppo
Kanjuro recovered shortly after his previous fight then tormented his former comrades by using his paint powers to create a fake Kozuki Oden, resulting in the death of Ashura Doji, but then Kanjuro was critically injured by Kin'emon. After hearing a certain village, she became fond of was destroyed, a rampaging Big Mom severally wounded two of the Tobiroppo Page One and Ulti, the former being defeated, but Ulti got back up and attacked, Nami, and Usopp and their young companion Tama; however, Nami knocked out Ulti after Zeus permanently fused with her Sorcery Clima-Tact, giving her the extra power that she needed to defeat Ulti. Thanks to the efforts of the alliance, every Gifter who ate Tama's special dangos became the child's obedient servants and, on her order, attacked their ex-crewmembers. This act played a key role in turning the tide of the battle in the alliance's favor.The Tobiroppo member and highly skilled former CP9 agent Who's-Who, despite all his strength and ferocity, was ultimately defeated by Jinbe an extremely powerful fish-man, a former Warlord of the Sea and the new helmsman of the Straw Hats. Sasaki proved to be a worthy adversary for Franky and even managed to heavily damage the durable mech-suit General Franky, but in the end, Franky emerged victorious when he fired a Franky Radical Beam at Sasaki's major weak spot: his large belly.

Black Maria underestimated Nico Robin and it cost her dearly. Robin saw through all of Black Maria's tricks and penetrated her defenses. After using new fighting techniques, she learned from her friends in the Revolutionary Army, Robin eventually wore Black Maria down and finished her opponent off with Grand Jacuzzi Clutch. Brook did his share by defeating the Black Maria's subordinates and then helped keep CP0 from capturing Robin.

Knowing he could not do anything to help as a child, Momonosuke asked Shinobu to use her power to turn him into an adult. This allowed him to transform into a giant pink dragon so he could fly Luffy back to the battlefield after he was temporally indisposed and then used his new power to create flame clouds to begin the important, long and arduous task of putting an end to Kaidou's sinister plot by preventing Onigashima from landing on the Flower Capital and instead change its course to have it safely land near the city as he moved the flying island with all of his might.

Taking on the All-Stars
Just when it seemed all hope was lost for Inuarashi and Nekomamushi as they were about to be killed by Jack in his mammoth hybrid form and Perospero with his candy axe respectively, the clouds cleared up due to a Haoshoku clash between Kaidou and Luffy, and the full moon allowed them to transform into their Sulong forms once more, allowing them to simultaneously defeat the All-Star and the Charlotte Family's eldest son.

Killer dueled Basil Hawkins as revenge for his earlier betrayal, but Hawkins used his straw dolls to transfer all damage to Killer's captain Kid which greatly hindered him in his and Law's battle with Big Mom. Fortunately, Hawkins made a grave miscalculation, since Kid's left arm was a metal prosthetic it was unfaceted by Hawkins' power, so Killer wound up slicing off his left arm and defeating him.

Queen is a brilliant and gifted scientist and a highly capable cybernetically-enhanced warrior with the abilities of a brachiosaurus, but he met his match in Sanji the son of a former colleague of his. Wishing to prove himself to be a superior scientist to Sanji's hated father Queen attempted to get the Straw Hats' cook to use his raid suit so he could compare Germa 66's technology with his own. Unfortunately for Queen Sanji destroyed his raid suit after he awakened the same genetic modifications as his super-powered siblings by wearing it multiple times; such as a body that is nearly invulnerable and an exhilarated healing rate. Throughout their fight Queen irritated Sanji by constantly reminding him of his heritage. Sanji was shocked and even more infuriated when Queen revealed that his cybernetics could mimic the abilities of the raid suits of him and his brothers who he despised so much. After Queen was revealed to be the one to have struck O-Some while he was invisible, Sanji became so enraged that the demented scientist made him doubt himself earlier and decided he had enough of Queen's cruelty and disrespectful behavior. By combining his massively increased strength and speed, new exoskeleton, and Busoshoku Haki, Sanji created a devastating new fighting style of blue flaming feet called Ifrit Jambe that would have been impossible before. With this new power, Sanji was able to overwhelm the All-Star and send him flying out of the Skull Dome and off Onigashima.

The strongest All-Star and Kaidou's right-hand man King, proved to be a formidable opponent for Zoro due to his lunarian inherited abilities, such as the power to generate and control fire, and the renowned immense toughness and vitality of his species. Fighting King was even more challenging thanks to his Pteranodon Devil Fruit, serrated sword, razor sharp spiked gloves and boots. Zoro quickly deduced that King was not a true swordsman, but rather a merciless thug who has a very different fighting philosophy than his own. As the battle raged on Zoro became grievously wounded and exhausted. However, Zoro hung in there, intensified his attacks and soon discovered a weakness he could exploit; when the flames on King go down his speed increases exponentially but his durability drastically decreases. With this knowledge Zoro was able to severally injure King thanks to the properties of the legendary Haki-powered sword Enma and his recently discovered Haoshoku Haki. When Zoro learned that the World Government were offing a lot of money for any information on King’s race the All-Star did not bother to answer his question as he believed the Straw Hat would be dead soon. King came to acknowledge Zoro as a capable swordsman worthy of remembrance, but he was unwilling surrender as he stated because he was a lunarian Zoro was biologically incapable of defeating him which Zoro found to be a weak excuse. As King launched his final attack Zoro was able use his newly developed King of Hell Three Sword Style to slice the giant flame dragon in half and cut off King's right wing in the process, causing the defeated All-Star to plummet from Onigashima. The result of this fearsome confrontation shocked both the Marys and CP0 to the core as this meant now all of the All-Stars and Tobiroppo had fallen in battle. Before passing out, Kanjuro painted a fiery creature called Kazenbo that was sent to detonate all the explosives in the Skull Dome's basement. However, this plot was foiled thanks to the interference of Yamato who froze the bombs just in time.

CP0 encountered Drake and Apoo the latter of which recovered from his fight from Zoro and defected from the Beast Pirates as he desired to take down whoever won the war. Even though Drake dealt serious damage to a CPO agent he was eventually incapacitated by a Shigan, while Apoo who realized he was no match against the might of two CPO agents and retreated. Izou and Maha, an elite agent of CP0, engaged in a duel which ended in a double knockout, causing the former's death and causing CP0 to fail at capturing Robin.

The Final Clash with the Emperors
Raizo won his duel against fellow ninja veteran Fukurokuju through his remarkable endurance. Despite being exhausted by the fight, he recruited the help of Jinbe and mustered enough strength to flood Onigashima with water through the power of his scroll-based ability, which prevented the deaths of their allies by extinguishing the fires caused by Kurozumi Orochi, Kazenbo, and King. While he was briefly trapped under a pile of rubble, Orochi was beyond shocked when he discovered that the geisha "Komurasaki" he was enamored with for so long was in reality his enemy Oden's daughter, Kozuki Hiyori as she exclaimed all her animosity towards Orochi while she informed him that every day, he sat on throne of Wano was a day too long and he was never truly the shogun. In a final attempt to take his revenge, Orochi attacked Hiyori with extreme fury, but was stopped by the timely arrival of Denjiro, who sliced off Orochi's last remaining head.

After several lengthy and difficult battles, against all odds, what was thought to be impossible happened; two of the Four Emperors, Kaidou and Big Mom, were defeated by three infamous pirate captains of the Worst Generation, all of whom achieved Devil Fruit awakening. Kid and Law pushed themselves beyond their limits during their battle with the monarch of Totto Land with her fire and lighting attacks, her powerful sword skills, how she miraculously healed herself and her drastic increase in strength. Still, they found a way to exploit a weakness of her soul powers and attacked the ruthless and destructive Big Mom with every ounce of power they had left. Law made the area around Big Mom soundproof so she could no longer extract soul foul fragments for anymore Homie-based attacks. Then Kid magnetized Big Mom in order to pin her down and unleased a mighty final attack to send her crashing through several of the Skull Dome's floors into the ground below the flying Onigashima with tremendous force.

Luffy pressed onward in the glorious battle, determined to defeat the devastatingly fierce and powerful Kaidou. Luffy chipped away at Kaidou's legendary durability after he became an advanced user of all three forms of Haki and using his newly acquired abilities in creative and unpredictable ways; demonstrating the extraordinary power of a forgotten time. Despite all of Kaidou's powerful, unrelenting attacks, Luffy was finally able to land a mighty punch with his giant fist the size of an island, causing Kaidou to fall so hard the collision made a massive crater leading into an underground chamber filled with magma, where both Kaidou and Big Mom's unconscious bodies ended up. This event caused a volcanic eruption where Onigashima once stood, signifying both their defeat and the official end of their era as rulers of the sea.

Progress
The following is a list of status updates provided by CP0 with the help of the Mary network.

Aftermath


In the end, the raid was a total victory with Kurozumi Orochi being dethroned and deceased. Meanwhile the Beasts Pirates lost all their power in Wano Country because of their leader Kaidou being defeated at the hands Monkey D. Luffy. This caused many of the Beasts Pirates to flee or be imprisoned in Udon and some of them had defected to the alliance's side during the battle either because of Chopper saving them from the biological weapon Ice Oni or because they were tamed by Tama. Also, CP0 agent Guernica also retreated via Geppo so he could report to the World Government everything that happened during the battle. Kaidou's precious New Onigashima Project that he had been working on for decades was now totally in shambles and Onigashima itself had landed near the Flower Capital instead of on top of the city as Kaidou intended thanks to the power of Dr. Vegapunk's Artificial Devil Fruit and Kaidou's once mighty fortress, the Skull Dome was now in ruins. After giving it much thought the rightful heir of Wano, Kozuki Momonosuke decided to postpone opening Wano's borders for the time being. With all enemy forces vanquished, Momonosuke became the new shogun and announced to his subjects that Kaidou and Orochi will no longer opress them. After hearing this the people of Wano rejoiced at their regained freedom.

Days later, the children of Wano receive new school teachers who told them the true heroic tales of Kozuki Oden, shrines were planned to be built so that Oden could finally be laid to rest, along with the members of the alliance that gave their lives for the rebellion, including Shimotsuki Yasuie, Ashura Doji and Izou, and everyone in Wano also soon learned of Komurasaki and Kyoshiro's true identities as Kozuki Hiyori and Denjiro. As Luffy asked Momonosuke to not give his name to the people of Wano, due to his humility, everyone in the country came to know him as the warrior Joy Boy and heard about the tale of how he defeated Kaidou with the citizens compering his heroism to Shimotsuki Ryuma and became forever grateful for ending his reign of terror.



Naturally, news of Kaidou and Big Mom's defeat soon spread across the seas; it was then before the banquet to celebrate the alliance's victory that Scratchmen Apoo arrived and showed those present the newspaper, which named the new Emperors of the Sea as well as an update on everyone's new bounties. It was announced to the whole world that "Straw Hat" Luffy and Buggy the "Star Clown" had replaced Big Mom and Kaidou as Emperors. Additionally, Luffy, Trafalgar Law and Eustass Kid had been assigned bounties of 3,000,000,000 each. To the dismay of the Five Elders, Luffy also got a new picture in his wanted poster showing the whole world his awakened form, and the Marines did not receive the order to remove the initial D in his name.
