Monkey D. Luffy/History/Final

To Egghead, Vegapunk's Laboratory
After they departed Wano Country, a beaten up Luffy was locked up in a cage by a furious Nami, who scolded him for his recklessness and carelessness in engaging in the Kid Pirates' and Heart Pirates' descent from Wano, which put the whole crew in danger while Luffy, in his competitive demeanor, did not realize the jeopardy of such a maneuver. Luffy was however, later freed from the cage after he apologized and then listened to Robin as she was reading the newspaper out loud to the crew. When she mentioned the news of the Levely events, in which Sabo was accused of murdering Cobra, Luffy remarked that Sabo would never do such a thing. When hearing upon Vivi gone missing during the Levely, Luffy suggested they would set out for Arabasta, but after being corrected by Zoro that Vivi was last seen in Mary Geoise so Luffy suggested that they head there instead, only to be once again shut down by Zoro who reminded him that they would walk straight into the enemies' dent. Luffy is then reminded of Ace once saying to him that Ace had his own adventures and that he would be trusted to handle himself until he would need help. Zoro then argued that they should have the same confidence in Vivi's, only to be taunted by Luffy, Nami, Chopper, and Sanji. Luffy was then asked by Robin if he wanted to hear more of the news but replied that he left it in her care and only to be alerted if something big happened. Luffy then laid down and told everyone about how his dream is so no one would have to give up their freedom and have it taken away like it happened to him as a kid. He then told everyone about the day Sabo, Ace and Luffy made an oath and told everybody what he told them, with the crew reacting with measures of surprise, disbelief and wonder and Usopp even telling him what Luffy wants is impossible despite his beliefs. Luffy then realized he never told anyone what he had told to Ace, Sabo and Shanks, but says that at the end of the dream that is what he wants.

Days later, the crew was sailing close to a Winter Island when they encountered a gigantic Warm Eddy, with a person inside. Just as Zoro cuts the current, Chopper, who walked outside wearing his new amigasa, was swept away by the resulting wind and Luffy, who tried to save him, was swept away as well. In the process of being blown away, he also caught the person recently freed from the eddy, who turned out to be Jewelry Bonney. While still in the air, she warned the crew of the threat below, just in time for the Straw Hats to evade the jaws of the Mecha-Shark. Jinbe then jumped overboard to save the three Devil Fruit users, but the four were separated from the Thousand Sunny when the Mecha-Shark fired cannons at them. Jinbe then swam them to the nearest island, where they dried off, and Bonney introduced herself. She explained that they were on Dr. Vegapunk's island base, Egghead and that she came without her crew as she had personal business with the genius professor, stating that he had turned her father into a mindless cyborg, and that she wanted answers, or revenge.

The four then entered the island, where they were bedazzled by the futuristic sights of giant robots, aliens and parfaits, until they interacted with them and found out they were all holograms. When a large robot girl talked to them, Luffy punched her out of frustration thinking she was also a hologram, only to find out she was real when he was punched back into an Automatic Cooking Machine, which the pirates delightedly started playing with. The large girl introduced herself as Dr. Vegapunk and explained the various technologies such as the Cooking Machine and her Light-Pressure Gloves before leaving them to continue her job of violence. After eating their fill, Luffy found and damaged a Trancos, allowing the four of them to change clothes. However, soon after a Pacifista police attacked them for stealing the food and clothes, and when Luffy attempted to fight back, Bonney intervened, tearfully revealing that her father was none other than Bartholomew Kuma. Thankfully, the four managed to evade the cyborg detection with Bonney's ability, who turned Luffy and Chopper into elderly people while turning Jinbe and herself into children. As they hid in a junkyard, Jinbe recounted to the other three of what he knew about Kuma, such as how he was the king of Sorbet Kingdom, but was driven out due to his tyranny, became a pirate, joined the Revolutionary Army and was eventually captured, but was released by Vegapunk to be one of the Seven Warlords of the Sea on the condition he becomes the scientists guinea pig for experiments in cloning and body modification. However, as Bonney rummaged through the junkyard, and finding a beam saber in the process (much to Luffy's delight), she denied several of these claims, believing they forcefully experimented on him, and while revealing that her father is of a special race, restored the Straw Hats to their original age.

The four eventually stumbled upon an ancient-looking but highly advanced robot, which an excited Luffy, alongside Chopper, wanted to ride. However, they could not find a place to ride on it and thought that it was automatic, causing them to try and make it move. Suddenly, the machine let out a huge impact, which Luffy was shocked by, and a man appeared stuck in the machine, begging for help. Luffy went to the man and helped free him. The man, who turned out to be Vegapunk, thanked Luffy and recognized him as Dragon's son. He then showed Luffy and Chopper how to make their shoes fly, though they ended up flying too high in the process.
