While Luffy and the others are enjoying the futuristic machines of Egghead, someone who resembles Bartholomew Kuma comes after them. When Luffy tries to fight back, Bonney stops him and reveals her shocking relationship with Kuma.

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 describes how he managed to grant the Seraphim Devil Fruit powers, which surprises Franky and the others. Meanwhile, Luffy is still facing Lucci in his savage, awakened form, but the rocket to the Labophase is about to leave.

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.

Lucci and Kaku from CP-0, who came to Egghead with a mission to eliminate the seven Vegapunks, ask Luffy and Zoro to uncuff them so they can fight alongside them against the Seraphim, but Luffy and Zoro are reluctant to do so.

The Straw Hats and CP-0 relentlessly attack the Seraphim, but the Seraphim keep getting back up. Then, Zoro notices that the Seraphim remind him of someone who he fought before. Meanwhile, Shaka goes to check one place where he thinks Vegapunk Stella might be.
