Episode 594

"Formed! The Luffy-Law Pirate Alliance!" is the 594th episode of the One Piece anime.

Short Summary
Luffy and Law agree on an alliance; the rest of the Straw Hats disapprove while Robin approves, even if she warns Luffy about a possible betrayal in a pirate alliance. Law switches Nami, Franky and Chopper's bodies again. Nami ends up in Sanji's body because Sanji is far away with Zoro and Brook. Law tells them that they can't go back once things start moving, for example capturing Caesar Clown who has the Logia type Gasu Gasu no Mi. He warns them that he is highly dangerous and therefore they need Haki users to beat him. Luffy says that the Haki users are him, Law, Zoro and Sanji.

The marines are continuing their fight against Caesar's men. The three centaurs open the door and see a big slop of slime that seeps out poison gas, most of them die and two survive so they run as it chases them. Caesar calls the pet slime monster Smiley and says that the Straw Hats and the G-5 marines are being used as test subjects for it.
