Highest Rating One Piece Arcs: AnimeOshi’s 2026 Definitive Guide


Which One Piece arcs truly reign supreme? We analyzed AnimeOshi’s 2026 community data to rank the top 4 highest-rated arcs. Let’s see if your favorite made the cut!

One Piece is a world-famous anime series that has had a massive impact on the globe for decades. In 2026, there are countless fans all over the world discussing the series, cementing its status as the "strongest" anime ever. While great titles like Demon Slayer, Jujutsu Kaisen, and My Hero Academia seemed to have the potential to overtake it, time has proven that no matter how strong the competition is, no other anime can truly defeat One Piece.

With the release of Volume 114, One Piece manga sales have officially exceeded 600 million copies. Between the success of the Netflix live-action adaptation and the long-awaited Elbaf arc set to premiere on April 5, 2026, there has never been a better time to rewatch the series. As we enter the Elbaf arc, the story will dive deep into the mysteries of the "One Piece" and Nika; doing some "homework" via a rewatch is now essential to keep up with the lore.

To truly understand One Piece, a rewatch is often necessary. However, since the series has so many episodes, knowing where to start and where to stop is a big question for everyone. As a huge One Piece fan, and by using data from AnimeOshi, I can help you decide what to watch and where to end each session. In this post, I will share the four arcs that received the highest ratings and explain why they are so highly regarded.

Before diving any deeper—since this post explores specific scenes—there will be some spoilers. If you haven’t watched One Piece yet, please stop here! One more thing to note: instead of following a ranking order, this post will follow the chronological watching order to ensure the best experience, as watching in the correct order can help you understand One Piece better.

The first high-rating arc to rewatch — Straw Hat vs. Heavenly Yaksha, the Dressrosa Arc (Episodes 629–746):

Based on the data on AnimeOshi, the first high-rating arc that everyone should revisit is the Dressrosa Arc. Across the whole arc, AnimeOshi recorded 243 ratings with an average score of 7.43 out of 10. While the score might not seem that impressive, One Piece is known for having a lot of filler episodes, which naturally brings the ratings down.

The Dressrosa Arc is always the best arc to rewatch — and even though it spans 100+ episodes, it has everything you could ask for. We got a strong and menacing villain, a touching reunion, a heartbreaking backstory, and most importantly, Luffy's first Gear 4 transformation. As a huge One Piece fan myself, I've rewatched the Dressrosa Arc multiple times and it still amazes me every single time. There are three parts I loved the most about this arc.

The first part is Sabo obtaining the Mera Mera no Mi. The Dressrosa Arc doesn't just give us a glimpse of one of Luffy's brothers, Sabo — it gives us the full scene of him claiming the Mera Mera no Mi at the Corrida Colosseum. In the world of One Piece, although the Mera Mera no Mi is a Logia-type fruit, it isn't considered particularly powerful, so whoever obtained it wouldn't drastically change the story. Anyone could have gotten the Mera Mera no Mi — but the fact that it was Sabo makes it deeply emotional and gives it a true meaning.

The Mera Mera no Mi was once Ace's devil fruit, so watching Sabo eat it gives us the feeling that Ace has returned — once again willing to fight for Luffy. One of Ace's dreams was to witness Luffy become the Pirate King. While Ace never got that chance, Sabo gets to witness everything on his behalf, as the next user of the Mera Mera no Mi. For those of us who have followed Luffy's entire journey, watching Sabo unleash the Fire Fist hits differently. Sabo eating the Mera Mera no Mi doesn't just give Luffy a powerful ally — it means Luffy has finally reunited with his brother, helping to complete Luffy's personal growth.

The animation throughout the backstory is excellent, and the voice acting is incredible. Law’s voice actor, Hiroshi Kamiya, and Corazon’s voice actor, Koichi Yamadera, did a great job portraying their characters beautifully. This arc is essential viewing; you should definitely keep Corazon’s ability in mind, as Law combines his own power with Corazon’s influence in a later season.

The final part I love most about the Dressrosa Arc is Luffy’s new technique: Gear 4. Personally, I think the introduction of Gear 4 leaves the strongest impression on everyone. The transformation is spectacular, and seeing Luffy completely overwhelm Doflamingo makes their fight a sequence you can rewatch over and over without ever getting bored.

While the entire Gear 4 segment is amazing, what I love most isn't just the animation or the combat, t’s Luffy’s facial expressions. Compared to other protagonists, Luffy is someone who almost always smiles, no matter the circumstances. However, once he transforms into Gear 4, he remains intensely angry. You may not have noticed, but Gear 4 Luffy doesn’t smile at all. This might seem like a small detail, but seeing Luffy’s fury directed at Doflamingo’s absolute domination really shows his determination to take down these "demonic rulers" for the sake of the people. In a world where many have become complacent under oppression, they need someone who is willing to get angry on their behalf—and that man will always be Luffy.

On AnimeOshi, the entire sequence of Law’s backstory (episodes 703–706) received a perfect 100% score! With such an incredible rating, it's clear that Law’s past is a must-watch for everyone. If you have the time, you should definitely experience it for yourself!

The second high-rated arc to rewatch: The Straw Hats vs. One of the Four Emperors — The Whole Cake Island Arc (Episodes 780–877)

According to data from AnimeOshi, the second arc recommended for a rewatch is Whole Cake Island. With 198 ratings, the arc holds a score of 7.31 out of 10. Similar to the Dressrosa Arc, the score might seem a bit low at first glance, but the presence of filler episodes inevitably impacts the overall rating. Whole Cake Island is an arc that tends to divide the fanbase; while many consider it a must-watch, others feel it's a waste of time. I can understand both perspectives, but I’d like to offer a different point of view. 

While some argue that it doesn't move the main plot forward as much as other arcs, the author experimented with many new elements here. Compared to other arcs, Whole Cake Island features the most complex family conflicts, a sister who sells children to the government, a "giant child" who unknowingly ate people, and a terrible man who groomed a child into a terrifying pirate. While Whole Cake Island may not shift the overarching story as drastically as others, it provides a different, darker look at the world of One Piece by portraying these more brutal themes.

The first part I love about the Whole Cake Island Arc is the battle between Luffy and Charlotte Cracker. As one of the Three Sweet Commanders of the Big Mom Pirates, Cracker uses the Bisu Bisu no Mi (Biscuit-Biscuit Fruit), a Paramecia-type Devil Fruit. As the name suggests, Cracker can generate and manipulate biscuits to create an infinite, highly durable army of biscuit soldiers.

Luffy had a difficult time against Cracker, and during the fight, he showed us several new techniques and forms. Luffy introduced the Gomu Gomu no Kong Organ, and in the climax of the battle, he revealed a new version of Gear 4: Tankman. Although Luffy hasn't used Tankman since, it demonstrated the incredible possibilities of Gear 4 and allowed him to finally defeat Cracker.

The second highlight is the emotional conflict between Luffy and Sanji. During the Whole Cake Island Arc, because Sanji is threatened by the Vinsmoke family, he has no choice but to act like a completely different person—even if it means fighting Luffy. Hurting his captain clearly haunted Sanji, but with his cruel family watching his every move, he felt he had no other choice.

The conflict between them is portrayed beautifully. Through this struggle, we truly understand how kind Sanji is and how Luffy possesses such an incredible heart, allowing his nakama to express their true feelings, even when they are painful. While there are parts of the Whole Cake Island Arc that you might feel like skipping, the saga between Luffy and Sanji is absolutely essential viewing.

The final part I love most about the Whole Cake Island Arc is the epic battle between Snakeman and Charlotte Katakuri. Katakuri is one of Big Mom’s sons and another of the Three Sweet Commanders. He ate the Mochi Mochi no Mi, a "Special Paramecia" Devil Fruit that allows his body to act like a Logia. Because he has awakened his Devil Fruit ability and possesses incredible Observation Haki, Katakuri is one of Luffy’s most formidable enemies.

The reason I love the clash between Snakeman and Katakuri is that it feels like the last battle where Luffy really had to use his brain to fight. For better or worse, once Luffy became "Nika," his style changed to laughing and playing; there is less of that traditional, high-stakes seriousness. The fight with Katakuri was the last time we saw Luffy fighting with pure, focused intensity, constantly thinking of a way to win. The Snakeman technique, King Cobra, is just so epic and animated with such high quality. No matter how many times I watch it, I am still impressed by this finale.

★★★ AnimeOshi Real-Time Data Corner ★★★

On AnimeOshi, the fight between Luffy and Cracker (Episodes 798 and 799) received a perfect 100% score! With a rating like that, it’s obvious that this segment is a must-watch for everyone. While I can’t deny that many people still feel the Whole Cake Island Arc is a waste of time, I believe that if you are looking for a different "flavor" of One Piece, you simply can't miss it.

The third high-rated arc to rewatch: The Straw Hats vs. Two of the Four Emperors — The Wano Country Arc (Episodes 892–1085)

According to data from AnimeOshi, the third arc everyone should revisit is the Wano Country Arc. With 366 ratings, the arc holds a score of 7.63 out of 10—slightly higher than the previous arcs we discussed. While this is still a bit far from a "perfect" score, we have to remember that Wano is massive, spanning three distinct acts, which naturally affects the overall rating.

Like many other long-running arcs, Wano contains its fair share of filler. For newcomers, I recommend trying your best to watch every episode, as the story is vital to the world of One Piece. However, for those who have seen it before, the parts that truly deserve a revisit are found after the raid on Onigashima begins. Whether you love it or hate it, the story before Onigashima focuses heavily on the samurai and the internal history of Wano. If you are watching for the "big picture" of One Piece, the Onigashima segment is the essential part to focus on, as it finally introduces the Sun God Nika.

The first part I love about the Wano Country Arc is when the Gomu Gomu no Red Roc strikes one of the Four Emperors, Kaidou. Episode 1015 went viral across the internet and remains one of the most beloved episodes in the entire series. Although it might sound hard to believe for a weekly show, the animation in episode 1015 is so spectacular that watching it feels like watching a high-budget anime movie.

In this episode, after an emotional conversation with Kin'emon, Luffy uses his powerful Red Roc tchnique against Kaidou, forcing the Emperor to the ground. This scene is incredibly hype and exciting; as Luffy finally reaches the rooftop battlefield, we finally see a glimmer of hope that Kaidou can be defeated. Kaidou is a monster who has been unstoppable for decades, but in this moment, his legacy begins to falter as Luffy punches him down.

The second part I love about the Wano Country Arc is Tama’s act of bravery. Although Tama is just a little girl, she showed every viewer just how strong a child can be during the raid on Onigashima. It might sound harsh, but between the samurai and the Straw Hat members, no one thought to count on a little girl as a source of power, especially since Onigashima was such a dangerous place to be.

Tama understood how terrifying Onigashima was—especially after seeing Kaidou's dragon form—yet she still went there with the help of the Gifters. Not only did she make it to the island, but she also had a brilliant plan and executed it bravely. It may sound hard to believe, but if Tama hadn’t been there, Luffy would have lost; the Beasts Pirates simply outnumbered them by too much. Thanks to Tama’s willingness to fight alongside everyone, the Straw Hats were able to turn the tide of the battle, eventually leading to a massive victory.

The last part I love about the Wano Country Arc is the awakening of the Sun God, Nika. For better or worse, once Luffy awakened this form, the scope of One Piece shifted significantly. It no longer focuses solely on current pirate wars, but now encompasses the entire history of the One Piece world. To truly understand the series, the awakening of Nika is a moment you definitely cannot miss. By connecting to this ancient history, Luffy no longer fights like an ordinary human; instead, he embodies a legend, jumping around and laughing constantly. While many fans dislike—or even feel annoyed by—Nika’s antics, we have to remember that this is their story, and we should embrace both Luffy and Nika.

From this point on, Luffy moves away from traditional combat logic, choosing instead to play and "fool around" during his fights. While this style of battling might frustrate some viewers, according to the legend, Nika must laugh all the way through. For those who can't stand it, think of it this way: in a world of terror and demonic domination where people die for irrational reasons, they desperately need a reason to laugh at even the silliest things. This is what led to the birth of the "Warrior of Liberation," the smiling warrior, Nika.

The last high-rated arc to rewatch: The Warrior of Liberation and the World’s Greatest Genius — The Egghead Island Arc (Episodes 1089–1155)

According to the data on AnimeOshi, the final arc everyone should watch is Egghead Island. Since this arc is effectively divided into two halves, let’s look at the numbers. The first part (Episodes 1086–1119) received 111 ratings with a score of 7.80. Meanwhile, the second part (Episodes 1120–1155) has 328 ratings and boasts a massive score of 9.43.

While the first part seems to have a lower score, it follows the pattern of previous arcs: it starts with slower pacing and some filler, which impacts the rating. However, once the story becomes highly focused, One Piece achieves high scores very easily—as seen in Part 2. The Egghead Island Arc is absolutely essential; it explains vital information about the world of One Piece and provides clues as to why everyone is searching for the Warrior of Liberation, the Sun God Nika.

The first part I love about the Egghead Island Arc is the reunion between Bartholomew Kuma and Jewelry Bonney. Kuma is a man who has walked through hell; he has lived in a nightmare since he was a child. He lived obediently under the orders of the world’s "true darkness," enduring every hardship thrown his way. But in the present, things have changed.

One of the Five Elders (Gorosei), Saint Jaygarcia Saturn, attempts to kill Kuma’s beloved daughter, Bonney. As a young girl captured by a terrifying monster, there was nothing Bonney could do but cry; after her attacks proved useless against Saturn, she was forced to give up. However, Kuma arrived. Whether he sensed her danger, whether Vegapunk left a fail-safe in his programming, or whether Kuma’s own bloodline awakened—there are many "maybes" behind how he could still move—the point is that Kuma finally decided to fight the darkness for his daughter’s sake. Kuma is no longer just enduring sadness and death; for Bonney, he doesn't care who the enemy is—he will fight to protect her.

The second part I love about the Egghead Island Arc is the epic "true" arrival of the Sun God, Nika. What I mean by "true" is that while Luffy used Gear 5 earlier against Rob Lucci, it is his transformation when Saturn tries to kill everyone that truly matters. Here, Luffy acts like Nika—not just by jumping and laughing, but as a warrior truly intent on saving everyone from hell.

It can be hard to understand why Gear 5 or Nika must constantly jump and laugh, but once you’ve seen the past—the suffering of Kuma and Bonney—it finally makes sense. For the two of them, they didn't want a military alliance or to be used by others just to defeat the darkness; what they truly needed was someone to set them free. If you were Kuma or Bonney, it might be hard to trust someone who suddenly claims they want to save you. However, someone who is simply jumping around, having fun, and laughing feels far more trustworthy than a serious leader who might just want to use you for their own ends.

The final part I love about the Egghead Island Arc is Bonney’s beautiful transformation into Nika. It might sound hard to believe, but during the battle on Egghead, Bonney transforms into Nika to fight against the Gorosei. At first, she didn't believe she could do it, but after listening to Luffy and finally trying, she actually became a Nika! I know this part frustrated a lot of fans; they worry that if Bonney can become Nika, then anyone could potentially do it in the future. While I understand that concern, I have a different view.

Between Kuma fighting Saturn and Bonney transforming into Nika, the story is showing us that the true hero isn’t someone else—it’s yourself. Kuma waited and listened for Nika his whole life, but Nika never came, so in the end, he had to be the one to fight for his daughter. Similarly, Bonney waited for years and felt helpless until now. Once they finally chose to fight for themselves, everything changed: Kuma was able to hug his daughter again, and Bonney was able to punch Saturn as hard as she could. Although "Nika" sounds like a legend in the One Piece world, to me, it is a symbol of fighting for one’s own freedom. In the end, it might really happen that everyone "becomes" Nika—not because of a Devil Fruit power, but because they finally choose to stop waiting and start fighting for their own lives, just like Luffy.

★★★ AnimeOshi Real-Time Data Corner ★★★

On AnimeOshi, episode 1151 received 13 reviews from scouts and holds a high score of 96%, while episode 1152 has 17 reviews with a 92% score. These are the specific episodes where Bonney transforms into Nika and fights for her own freedom. The data shows that the shift in the story is truly dramatic; even if you are someone who dislikes this direction, these episodes are still an absolute must-watch for everyone!
