One Piece's Wano Arc anime has just started an epic battle, where Luffy attacks Kaido with a powerful punch that actually resulted in Kaido bleeding, which shocks everyone. Now, fans are hyped for what's to come, as they are expecting a sequence of epic battles to take place soon, starting with the Supernovas against Kaido and Big Mom.
While One Piece is among the most popular and beloved anime worldwide, it inevitably has its fair share of bad episodes, given that it has released 1000+ episodes in 23 years. Unsurprisingly, most of these are filler episodes, which fans sometimes think are a waste of time. Whether they don't move the plot forward, feature nonsensical conflicts, or simply aren't entertaining, some episodes are better left only watched once.
Episode 291: Boss Luffy Returns! A Dream or Reality Lottery Trouble- 6.1
This episode occurs on Jipangu, an alternative reality modeled on feudal Japan, where the Straw Hat Pirates and the Buggy Pirates live. The Buggy Pirates' captain, Buggy, tries to sell Rika as a slave to act as payment for Pandaman's debts, believing Pandaman to be Rika's father.
It is a filler episode and is a part of the 2-episode Boss Luffy Historical Arc. Fans are disappointed at how this episode is suddenly put in the middle of a heated battle during Ennies Lobby Arc, right after Chopper started rampaging in his battle against Kumadori, a member of a group of betrayers, 9.
Episode 492: The Strongest Tag-Team! Luffy and Toriko's Hard Struggle!- 6.0
As its title states, this episode is a crossover between One Piece and Toriko. In this episode, Luffy and Toriko meet up on Hungry-la Island. where there exist animals exclusive for this episode only. They also eat the Multi-fruit (a fruit from Toriko's world), after they rescue Komatsu and Nami from the Cocoalas who kidnapped them.
While it is cool to see characters from other anime in One Piece, the episode doesn't really have any significance to the overall storyline. A likely reason as to why the episode was rated poorly was because it is released right after the Marineford War, where fans saw the death of two fan-favorite characters, Ace and Whitebeard (and Luffy nearly died).
Episode 1005: The Power of Ice Oni! A New Version of the Plague Rounds!- 6.0
Several occurrences occur in several locations on the floating Onigashima Island in this episode. On their way to the Emperor, Luffy, Sanji, and Jinbe fight their way past Kaido's minions. Queen infects both allies and foes with a virus that turns them into ice monsters. The scabbards hit Kaido with a weaker version of Oden's hallmark technique together, which didn't do much.
While the episode seemed to have improved its infamous pacing as compared to the previous episodes, it still felt a lot slower even when compared to the manga. Some scenes deemed unnecessary and filler by fans are still present in the episode, particularly when the scabbards attack Kaido together, and flashbacks of their time with Oden is shown repetitively..
Episode 896: Side Story! Clash! Luffy vs. the King of Carbonation!- 6.0
Luffy confronts Cidre in this episode, who is equipped with his most powerful carbonated gear. After that, Luffy is invited to the Pirates Festival, and the former Cidre Guild offer the Straw Hats countless barrels of cola for free. The Straw Hats travel to Delta Island for the Pirates Festival, where they learn that a race for Gol D. Roger's treasure would be held.
Alongside Episode 895, this is another filler episode that serves as somewhat of a prequel to One: Piece Stampede. It is put right after the events in which Luffy Meets Tama, a girl Ace once met on his travel to Wano. Fans didn't really like having this episode released out of nowhere after an emotional scene in Episode 894 where Luffy reveals Ace's death to Tama.
Episode 881: Going into Action! The Implacable New iral of the Fleet- Sakazuki- 6.0
The narrative of the episode takes place at New Marineford, where Sakazuki, the new Fleet iral of the Marines, discovers that iral Fujitora has gone to Mary Geoise. iral Ryokugyu, the mysterious iral, is then ordered to send him away. Meanwhile, ex-Fleet iral Sengoku describes the events of two years ago at Impel Down and Marineford.
While the episode cannot really be considered a filler episode, it also doesn't add much new information to the series. While the beginning contains fresh content, the rest of the episodes are just pure flashbacks of events from previous arcs- albeit animated better. This left fans bored, especially those waiting for Wano Arc to come.
Episode 590: History's Strongest Collaboration vs. Glutton of the Sea- 5.8
This is the first episode in which One Piece, Toriko, and Dragon Ball have all collaborated at the same time. Multiple characters from the three animes compete in the Tastiest Under The Heavens tournament held by the International Gourmet Organization in order to win the legendary Carat Sizzled Cattle. They must survive multiple obstacles filled with traps and monsters in a Winner-Take-All survival race to obtain the meat.
Aside from the protagonists, ing characters such as Toriko's Sunny and Komatsu and Dragon Ball's Vegeta and Piccolo have appeared in the crossover episode. While it is fun to watch a crossover episode between several anime, it is completely skippable, and some fans think that it is a waste of time, which caused its low ratings.
Episode 1007: Zoro's Pursuit! Ice Oni Tag- 5.8
As the raid on Onigashima Island continues, one of the most powerful villains, Kaido, and his minions are busy fighting the alliance down. The All-Star, Queen is still infecting everyone with a virus. On the other hand, Kaido is fighting the Scabbards, and the Tobiroppo Sasaki's forces are fighting Yamato, who re Kozuki Oden's demise.
Like several Wano Arc episodes, fans have complained about how slow this episode is. Reasons include several scenes taking way longer than necessary (such as Queen's dancing), redundant flashbacks about Oden being shown again, and several minutes of scenes that didn't even exist in the manga taking place in this episode.
Episode 1006: I Won't Forgive Him! Chopper's Determination!- 5.8
In this episode, Yamato still rushes after Shinobu and Momonosuke to convince them about being allies. On the other hand, Shinobu is concerned that as Kaido's daughter, she would endanger Momonosuke. Meanwhile, Queen is continuing to infect foes and allies with his virus.
Again, fans generally didn't like how little manga content is adapted in this episode (although it is more here than in some other episodes). Also, despite the title having Chopper's name on it, Chopper actually only appears for a minute in this episode, and it wasn't even during its climax. These factors contributed to its low rating.
Episode 292: A Big Rice Cake Tossing Race at the Castle! Red Nose's Plot!- 5.8
The Grand Mochimaki Race, a celebration about catching a Mochimaki with a great treasure within, takes place in this episode, but Buggy has a plan to steal the treasure before the festival begins. Zoro eventually obtains the treasured Mochimaki, but he discards it.
It's a filler episode, just like Episode 291, and it's part of the two-episode Boss Luffy Historical Arc. Fans are dissatisfied with how this episode is thrown into the heart of a hot battle during the Ennies Lobby Arc, just after Chopper went on a rampage against 9 member Kumadori. Thankfully, its next episode is a canon episode of Ennies Lobby Arc.
Episode 336: Chopperman to the Rescue! Protect the TV Station by the Shore!- 5.5
In this episode, Chopper Man and Namifia are both cash-strapped. Meanwhile, Dr. Usodabada devises a scheme to bring down Chopper Man while gaining renown and forming a new crew to replace his uncooperative partners, Sanjilops and Zorogilla. His objective is to seize control of the television station and broadcast his demands live.
The episode happens right before one of One Piece's weirdest arcs, the Thriller Barc Arc, where the crew meets Brook for the first time. Aside from being a part of an 11-episode filler episode sequence, the reason for the low ratings is that fans think that the episode is somewhat cringy and childish and that it is an utter waste of time.
