Ep 608. A Mastermind Underground! Doflamingo Makes His Move!

As Luffy, Zoro, and Viola continue their search for Caesar Clown, Joker (aka Doflamingo) puts plans into motion from underground. He meets with Vergo, his loyal henchman, and discusses their next move. Meanwhile, Sanji and Kin'emon continue their disguise as Doflamingo's subordinates in order to infiltrate his organization.

Back in Doflamingo's lair, the Shichibukai reveals his intentions to stir up chaos in the New World by selling weapons made from Caesar's research. He also reveals that he is aware of the Straw Hats' involvement with the dwarves and their search for Raizo. This knowledge puts them in danger as Doflamingo declares war against the Straw Hats and anyone who associates with them.

As the Straw Hats get closer to Caesar's laboratory, they encounter yet another obstacle - a giant robot guarding the entrance. Luffy, with his Gum-Gum powers, tries to take on the robot but is overpowered. However, with the help of Zoro and Viola, they are able to defeat it and make their way inside.

Sanji and Kin'emon, on their undercover mission, come across Doflamingo's "Toy House," a place where humans are turned into toys and forced to work for him. They see a familiar face among the toys - their friend, Thunder Soldier. They vow to rescue him and put an end to Doflamingo's cruel reign.

As the Straw Hats continue to make their way through Caesar's laboratory, they are attacked by a group of powerful subordinates. Luffy faces off against one of them, a powerful logia user named Smoker, while the others battle the rest. However, they are soon outnumbered and outmatched, and things take a turn for the worse when Caesar himself appears.

Doflamingo, watching from underground, laughs at the sight of his enemies struggling. He declares that he will destroy them all and take control of the New World. The Straw Hats are left to wonder what they can do in the face of such a powerful foe.

As the episode concludes, the stage is set for an epic battle between Doflamingo and the Straw Hats. Will they be able to overcome his schemes and rescue their friends? Only time will tell in the next installment of One Piece.
