The saga is still ongoing and it will continue for quite some time. There are four arcs in the saga so far; the most recent arc in the saga is Wano. All the arcs in the saga are extraordinary and very well-written. Here all the arcs in the Four Emperors Saga ranked.

4 ZOU ARC

Zou arc is the first arc in the Four Emperors Saga. It starts after Luffy and co. take down Doflamingo and go to Zou to reunite with the rest of the crew. But, the crew was in for a surprise when they arrived on Zou. Sanji had left the crew! He left the crew for the sake of the safety of the crew. He was left with no choice but to go willingly with Capone Bege. Luffy was surprised to find out about Sanji leaving the crew without any reason. A lot of characters were introduced in the arc; some of them would go on to play a very important role in the future. The arc featured the creation of a new alliance— Ninja-Pirate-Mink-Samurai Alliance, that would take down Kaido. The Straw Hats also found out about the existence of a Road Poneglyph. The fans were expecting that the crew would be united once again, however, it wasn't the case. The Straw Hats split up once again. Luffy, Nami, Chopper, Brook left for Whole Cake Island- the territory of Big Mom. They were accompanied by Carrot.

3 LEVELY

Imu One Piece

The Levely arc was terse in comparison to Whole Cake Island. It focused on the events after the conclusion of the Whole Cake Island arc. This arc was filled with surprises. First, Luffy's new bounty was revealed, which was 1,500,000,000 beris. Secondly, the whereabouts of the Revolutionary Army were revealed. They had managed to leave Baltigo unscathed. Thirdly, the Revolutionary Army declared war on the World Nobles. Finally, there was the appearance of Im, a mysterious figure to whom even the World Nobles bow down. The arc was fast-paced and there was a lot of stuff of happening throughout. Also, it is impossible to ignore the appearance of Shanks at Mary Geoise and talking to the Five Elders. The arc showed that the world was going to be changed soon.

2 WHOLE CAKE ISLAND

The main focus of the arc was Sanji. Luffy and co. went to the territory of Big Mom to bring back Sanji. It wasn't going to be an easy task by any means. The arc featured the best fight in One Piece to date. Several mysteries were unraveled. The fans found out that Sanji is actually related to the notorious Germa 66. The arc has been subject of severe criticism mainly because there weren't as many fights as the fans would have liked. But, the main purpose of the arc was to focus on Sanji as a character and how far he had come. He was labeled as a failure by his own father. He was ostracized by his own family; only his mother cared for him.

Sanji was saved by Reiju who freed him from his cell. After a chain of events, Sanji ended up on Zeff's ship. Sanji considered Zeff his father, and Big Mom threatened to kill Zeff and all the cooks at Baratie. There was also a looming threat over his crew. Sanji chose to sacrifice himself in order to save everyone else. He was betrayed by Pudding as well, who was supposed to be the shining light in his dark time. The arc featured an unsuccessful attempt at assassinating Big Mom. We also got to see her backstory.

Towards the end of the arc, we saw Luffy beating Katakuri. Big Mom was rampaging and she wouldn't stop until she had eliminated every Straw Hat. There was only one way to stop her and that was to bake her a magnificent wedding cake. This was Sanji's biggest challenge to date, but he stepped up and made a marvelous cake, which stopped Big Mom and saved the Straw Hats from total annihilation. Also, who can forget Luffy ordering Jinbe to come to Wano and join up with the rest of the crew. The arc was unpredictable and fun. It showed that it was futile to try and predict what Oda was up to.

1 WANO

Wano is undoubtedly the best arc after the time-skip. It is going to be a long arc for sure. The first two acts are over; the third act is currently going on. The main antagonist of this arc is none other Kaido, one of the four Yonko. Luffy and Law formed an alliance all the way back at Punk Hazard to take down Kaido; now they have a chance to take him down. The arc is far from finished. So far the arc has been breathtaking. The fans found out the bounties of the current Yonko, Whitebeard and Gol D. Roger. The incident involving Rocks was also revealed. Also, the introduction of Kozuki Oden left the fans stunned. His backstory added more spice to the arc. The culmination of the Wano arc is expected to rival that of Marineford. It has certainly got the potential to become the best arc in the series to date. There will be a lot riding on Oda's shoulders, and hopefully he will deliver.
