A young girl who came out of the big robot names herself Dr. Vegapunk and it surprises Franky and the rest of the Straw Hats. Meanwhile, Luffy’s group gets to the surface of the island where futuristic buildings stand and unknown giant creatures wander about.

The Straw Hats without Luffy, Chopper, and Jimbei are taken to the laboratory on the clouds far above the ground by Lilith. They get excited about the things they've never seen before. However, inside the laboratory, a new threat is waiting for them.

Nami and the others are attacked by a Pacifista who resembles Jimbei and while they’re in battle, some of Vegapunk’s Satellites look on with excitement. Meanwhile, Luffy and the others find something extraordinary at the scrap heap.

Vegapunk Shaka shares with Robin and the others his theory about an ancient kingdom and the 100-Year Void. He even says that he visited Ohara after its destruction. Meanwhile, Luffy and Chopper try to activate the giant robot and something surprising happens.

Shaka reveals the secret behind the foundation of the Revolutionary Army and how the relationship between Vegapunk and Dragon affected it. Meanwhile, Vegapunk explains to Luffy and the others about his special power and how his clones work.

Vegapunk reveals the shocking history of the ancient giant robot and asks Luffy to take him off Egghead. Rob Lucci and his fellow Cipher Pol agents arrive at the island and ask for permission to enter the port.

CP-0 led by Rob Lucci makes a forced landing at Egghead and people on the Fabriophase are plunged into confusion while Shaka and the others prepare to fight back on the Labophase. The enraged Atlas stands up to defend the peace of the island.

Luffy transforms into the Warrior of Liberation as Rob Lucci also shows his awakened Devil Fruit form. As the two clash, Vegapunk reveals the shocking truth of the Gum-Gum Fruit and his eye-opening theory on Devil Fruits.

Vegapunk asks the Straw Hats to take him on board their ship which makes Franky and Usopp happy but annoys Nami. Lucci orders his troops to block off all Vegapunk’s escape routes and looks to invade the heavily-secured Labophase.

CP-0 enters the Labophase and starts attacking the Thousand Sunny as soon as they find it. Luffy reunites with Nami and the others but finds out that Vegapunk is missing. Meanwhile, Bonney is pressing Vegapunk to change back her father Kuma.

The Seraphim come following CP-0 to the Labophase, pitting Zoro and Brook against the seven of them. Sanji, Franky, Edison, and Lilith leave the lab to fight them, but the Seraphim launch a full-scale attack on the lab.

Stussy suddenly knocked out Lucci to the Straw Hats’ surprise, and when Shaka reveals her true identity, they’re stunned again. Meanwhile, a major incident occurs on an island called Sphinx where Whitebeard came from.
