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 Hat Pirates disapprove while Nico 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 not 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.

Long Summary
The episode begins with Law explaining his proposal of an alliance to Luffy and Nami. Law reveals he has found a way to take down one of the Four Emperors but Nami disagrees with the idea of forming an alliance and tries to convince Luffy not to agree. However, Luffy asks Law which one of the Four Emperors he is talking about and after hearing his answer he agrees to his proposal, leaving Nami shocked.

Back at the Straw Hat Pirates' camp, Usopp and Chopper are shocked by the news of an alliance with the Heart Pirates, causing Usopp to yell at Luffy for returning with such an eccentric idea whilst Nami points out that everyone disagrees with the proposal. Law then asks Chopper to treat Franky (in Chopper's body) leaving Chopper frantic at how badly hurt his body is and immediately tries to bandage it up. Robin states she is happy to go along with Luffy's decision but also warns him that alliances are often marked by betrayal and that it's dangerous for him since he is so trusting. In response, Luffy asks Law if he will betray them and when he answers no Luffy smiles with absolute trust, prompting Usopp to yell at him to at least have some doubts. Luffy says to his crew that Law is a good man but even if he isn't he has all of them, who have been training for 2 years, to rely on. Nami, Usopp, Chopper and Franky then become flattered by how much their captain believes in them. Law then puts Franky and Chopper back into their respective bodies whilst Nami is put into Sanji's since Sanji (who is in Nami's body) isn't around, leaving Nami upset and asking Law if there is anything he can do but he explains that there isn't.

Law then reveals that the children are drugged but Chopper replies that he already knows and expresses his desire to send the children home for them to recover. Law further reveals that turning people into giants was a project by the World Government, presumably for military purposes, and that Caesar had wanted to achieve it first as it means to surpass both Vegapunk and the World Government. Law then questions if Nami really wants to help the children and she replies that she does, as she thinks of the children who had asked for her help with tears in their eyes, and firmly states that she will not leave the island unless she knows for certain that the children are safe. Law asks if she will be willing to stay on the island alone, as he has no intention of aiding the children, however Luffy says that he will not leave his friends behind and that Chopper's and Nami's wish is his as well. Luffy also informs Law that Sanji wanted to help the samurai and that if he wanted to team up, he will have to help them. Usopp sighs and explains to Law that Luffy's idea of an alliance is different from that of Law's. Deciding to compromise, Law splits the tasks, telling Luffy to take care of the samurai while he researches the drug, requesting the Straw Hat Pirate's doctor to go with him. Chopper is then comically tied onto Law's hat, as he is too injured to move, which prompts everyone to laugh at the scene and leaves Law embarrassed.

At the burning lands, the centaurs are unlocking the huge door. They walk in and encounter a massive shape, but they cannot tell what it is due to the darkness. A centaur steps closer but clutches at his throat and falls. Gases are release in streams around the shape.

Law carries Chopper by tying a rope around his sword with the other end tied to Chopper. Law then warns Luffy and his crew that Caesar is going to get rid of almost everyone on the island and reclaim the children as he cannot risk the government finding out about the island, which is his perfect hiding spot. He informs them that Caesar has a 300 million bounty, owns weapons of mass destruction and that people who cannot utilize Haki should avoid him. Luffy says that there are only four Haki users available: Law, Zoro, Sanji and himself.

Law answers Luffy's question and confirms that their objective is to kidnap Caesar. However, despite the Straw Hat Pirates being puzzled at to the reason why they must capture him, Law chooses not to explain, saying that there is no point in telling them when Caesar has not been kidnapped yet and asks them to focus because it will not be an easy task. He further warns them that when Caesar is captured, the ball will start rolling and there will be no turning back, giving them the final chance to reconsider their decision. However, Luffy says that it is fine and remains steadfast.

At the fight between the Marines and the centaurs, Tashigi has identified some of them as former prisoners. Smoker is confused and wonders why four years ago, the government had said that there were no survivors.

The Den Den Mushi is ringing but Caesar refuses to answer it, having already predicted the nature of the call. True to his words, the centaur at the burning land is trying to contact Caesar. Something has flown out of the door that was opened and had killed all except two of the centaurs, who are now running. However there is no escape from the slimy like substance flows throughout the land, leaving a wake of destruction behind. It releases a cloud of gas that engulfs the centaurs and they slowly choke and faint. Caesar explains to his subordinate about his pet, saying that it is a very rare type of slime-like creature. He names it Smiley and states that no one will be able to leave the island.
