Monkey D. Luffy/History/Final

Egghead Arc
Once the Sunny landed at the bottom of Wano Country's waterfall and the Straw Hats recovered, Luffy was severely beaten by Nami and placed in a cage; he apologized for his reckless actions and pleaded to be let out. Later, Luffy was released and learned from the newspaper that Nefertari Vivi was missing, her father Nefertari Cobra was dead and Sabo was credited with his killing. Luffy grew angry and distressed at this, proclaiming that Sabo would never do something like that and wanting to go to Mary Geoise to rescue Vivi. However, Zoro talked him down, saying it would be foolish to attack the city and that they needed to let Vivi live her own life until they knew for sure it was necessary to act. Robin then revealed the news that Buggy was now one of the Four Emperors, which a surprised Luffy believed was a mistake. She offered to share more news regarding other people Luffy knew, but Luffy declined unless it was truly bad. Luffy then reaffirmed Sabo's innocence and revealed the dream he had shared to Sabo and Ace 12 years ago; the revelation of this dream provoked a strong response from the Straw Hats, with reactions ranging from delighted laughter to stunned silence. However, everyone supported it and expressed a drive to find the final Road Poneglyph that would allow them to reach Laugh Tale.

Days later, the Straw Hats entered a bitterly cold area as they drew closer toward their next island. Luffy saw a gigantic warm eddy and then noticed something inside of it, causing Zoro to cut it open. The strong winds blew Chopper overboard and Luffy stretched out to grab him, but was swept overboard as well. The mysterious figure then emerged from the eddy, revealing herself to be a child Jewelry Bonney. Luffy stretched out his other arm to grab Bonney, but they were then attacked by a giant Mecha-Shark living in the water, causing the three of them to fall into the ocean. Jinbe dove in to save them, and was forced to take them deep down to escape the Mecha-Shark. They made their way to a cave in the coast of the island, where they dried their clothes and Bonney explained to Luffy that she was a fellow member of the Worst Generation. Luffy wished to look for a restaurant to get food, but Bonney said he would not find one as this was the Future Island Egghead, which contained Vegapunk's laboratory. Bonney revealed that she came here to take revenge on Vegapunk for turning her father into a mindless cyborg.

Luffy, Chopper, Jinbe, and Bonney ventured into the cave and accessed Egghead's surface via a ladder, where they found themselves surrounded by futuristic machines. However, Luffy found that a lot of the creatures and food around him were nothing more than holographic illusions. Atlas, a satellite of Vegapunk, then appeared and Luffy punched her to see if she was real, causing her to get angry and punch him back. However, he landed against the Cooking Machine which could make any food on demand, which he, Chopper, and Bonney gorged on. When Jinbe asked Atlas who she was, she responded that she was Vegapunk, which Luffy and Chopper took at face value. Once the group had eaten their fill, Atlas departed, and Luffy discovered a machine which gave him new clothes. The rest of the group used the machine as well, but were then approached by a police Pacifista which attacked them for using the cooking and clothing machines without paying. Luffy moved to launch a counterattack against it, but was kicked away by Bonney, who believed that the Pacifista was her father Kuma. Knowing this was not the case, Luffy rushed to save her from its laser attack. Following the blast, Bonney used her Devil Fruit ability to change everyone's ages, causing the Pacifista to no longer recognize them. As they recovered, they talked with Bonney about Kuma's past and how he came into the World Government's service.



Luffy's group resumed exploring Egghead, and came to the ruins of a very old mecha in a big scrap heap. While trying to get it to activate, a sudden burst happened as an old man, the original Vegapunk, appeared with half of his body inside the mecha due to a failed teleportation experiment. Luffy pulled him out, and noticed that he was floating, which Vegapunk revealed was a function of the DOM Shoes they were all wearing. However, their attempts to activate this caused them to blast high into the air. Following this, Vegapunk explained more about himself to the pirates, including how he split his consciousness into six satellites which included Atlas. Bonney then tried attacking Vegapunk with his Beam Saber invention, but fainted after the beam attracted a horde of bugs. Vegapunk talked to Luffy about Momonosuke and his dragon transformation, revealing it was the result of his artificial Devil Fruit creation. Luffy then asked about the mecha, and Vegapunk revealed that it was the Iron Giant, which had been built 900 years ago and attacked Mary Geoise 200 years ago. Vegapunk then asked Luffy to take him off of Egghead. When Luffy asked why, Vegapunk revealed his main dream of creating a free and abundant energy source for the whole world, an energy which once powered the Iron Giant centuries ago. However, this research caused him to delve too deep into forbidden history, resulting in the World Government now looking to eliminate him. Vegapunk then noted that CP0 was now on Egghead, and reiterated his request to sail with Luffy. Luffy agreed because he liked the scientist's funny-looking head, and Vegapunk requested he take Bonney to the Labophase above the clouds before this area became a warzone, saying he would meet them up there as he suddenly disappeared into thin air.



As Luffy's group started heading to the requested location, they ran into Rob Lucci, who had just taken down Atlas using Rokuogan. Initially ambivalent toward Lucci, Luffy became angry upon seeing what had happened to Atlas due to Atlas giving him food, and activated Gear 5 to fight the CP0 agent. Lucci countered by activating his awakened leopard Zoan form, and the two of them engaged in a fierce battle. In the midst of their sparring, Sentomaru arrived with the Seraphim S-Snake, S-Hawk, and S-Bear to counter CP0's invasion, but was struck down by Lucci while distractedly conversing with Luffy. Sentomaru managed to remain conscious to prevent CP0 from assuming control over the Seraphim, and Luffy used his environment and awakened abilities to keep Lucci away from him, overwhelming the CP0 agent. Sentomaru told Luffy to go and get Vegapunk off Egghead, and Luffy joined Chopper, Jinbe, and a now-conscious Bonney as they took the Vacuum Rocket up to the Labophase, which they reached in seconds.

Bonney quickly raced into the Labophase, still intent on getting revenge on Vegapunk, and Luffy and Chopper raced after her to stop her. He, Chopper, and Jinbe reunited with Nami, Usopp, Sanji, Robin, and Franky, but lost track of Bonney and Vegapunk in the process. Luffy and Chopper went to look for the two of them, but could not find them even after searching the entire Labophase, returning to the control room with the rest of the Straw Hats, all six of the Vegapunk satellites, and undercover CP0 agent/Vegapunk ally Stussy, who had incapacitated Lucci and Kaku. Satellite Shaka noted that they had lost control over the Frontier Dome that protected the Labophase from outside attack, meaning they were unable to get out of it. He told the group to do what they could to find the main Vegapunk, and as they all dispersed, Luffy remained in the room along with Zoro to recover from his exhaustion and watch over Lucci and Kaku. Originally able to hear everyone through a headset, the signal cut out and Luffy went to Shaka to find out what was going on. Shaka revealed that the camera feeds around the Labophase were being rapidly cut off, meaning there was an enemy on the loose inside the Labophase. Zoro then called for help, and Luffy and Shaka raced to him to find S-Hawk and S-Bear had arrived. The two Seraphim began attacking despite Shaka's orders, making him realize that one of the Vegapunks had ordered them to attack.



Now conscious, Lucci and Kaku proposed that Luffy and Zoro free them of their Seastone shackles so they could team up against the Seraphim, which the two Straw Hats found unappealing. Kaku promised they would go back in handcuffs once they were finished, and Luffy believed this, forcing Zoro to explain Kaku was lying. However, Luffy ultimately agreed to free them, saying he would beat them if they tried going after his friends. Luffy activated Gear 4 and he and Lucci performed a combined attack against S-Bear, while Zoro and Kaku attacked S-Hawk. Despite their powerful combined attacks, the Seraphim were able to get up little worse for wear; however, Zoro did notice that their physiologies were similar to King, who was a member of the rare Lunarian Tribe. As the battle raged on, Shaka departed to join the search for the main Vegapunk. With the knowledge that the Seraphim's strength was dependent on the flames on their backs, Luffy's group moved to diminish those flames, to little initial success. S-Hawk then disappeared suddenly, and Lucci revealed that it was going to eliminate its weakest targets first. Zoro raced after it, and Luffy told Kaku to go with Zoro before turning his attention back to S-Bear.
