'One Piece' Chapter 921 Release Date, Spoilers: Jack Will Finally Make an Appearance While Emperor Kaido's True Power Is Unveiled

"One Piece" chapter 921 is going full speed ahead with the manga's Wano Country arc. With most of the Straw Hat Pirates already reunited with Luffy, the setting's big bad and the reason to fight him has finally been revealed.

The previous chapter has already set up the Straw Hat Pirates to take up Clan Kozuki's cause of eliminating Emperor Kaido in “One Piece” chapter 921. The Kozukis were once significant lords in Wano Country until their Lord Oden and his wife were killed by none other than Emperor Kaido himself. Since then, Lord Oden's followers and son have time-traveled from the past to hopefully re-establish the Kozuki name in the future and eliminate Emperor Kaido in an act of vengeance.

Spoilers were recently posted on Reddit showing a more in-depth look into “One Piece” chapter 921. It seems that the oft-mentioned Jack will finally be making an appearance in the series's upcoming chapter. Unfortunately for fans who have been constantly hyped about Jack's power and influence, it looks like the enforcer boss will be taken out quite easily by the samurai Shutenmaru.

The “One Piece” chapter 921 spoilers also have images of Emperor Kaido in what appears to be his Dragon form. While a spoiled image does mention that Luffy and Law have comments about Kaido's power, it is unclear whether they are reacting to a story being told to them, or if they are already encountering the Wano Country arc's main antagonist in person.

Fans may be pretty excited about the upcoming chapter due to last week's Shonen Jump not featuring the Straw Hat Pirates. Fans looking forward to finding out more about Emperor Kaido's power over Wano Country and the standoff between Jack and Shutenmaru can catch “One Piece” chapter 921 when it is officially released on Oct. 22.
