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 while the rest of the Straw Hats disapprove while Robin approves, even if she notices 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. Caesar has the Gas Gas Fruit and is a Logia user. Therefore, they need haki users to beat him for example: Luffy, Zoro, Sanji and Law himself.

The marines are continuing their fight against Caesar's men. The three centaurs open the door and see a big glop of Slime that seeps out poison. Caesar calls the pet slime monster Smiley and the Straw Hats including the G-5 marines are being used as test subjects for that venom monster.
