Warning: Spoilers ahead. Details of the next episode of "One Piece" anime will revealed. Read on if you want to know the details.

Although "One Piece" fans are continually questioning about Sanji's whereabouts, the next chapter of the anime manga 810 is suspected to be all about Jack and many more details about his human form.

As speculated by Movie News Guide, there are two characters that might be related to Jack after-all and this were "Yonta Maria Grand Fleet Adventurer "Massacre Ruler" Orlumbus and Shichibukai Pirate Edward Weevil (Whitebeard Jr.)."

This speculation of Jack's relation with these two characters were based from his after features of becoming a human.

"In the "One Piece" chapter 810 spoiler image, Jack was shown to be a very huge pirate captain, about 9 feet tall. He had two braided hair similar to Weevil and an impression like Orlumbus," according to Movie News Guide. "He wore two curved horns at his ears and two mammoth tusks branching from his back. Just like Donquixote Pirates Captain Doflamingo, he also wore a feather-like coat that had metallic shoulder pads, which had horns too."

Apart from this, the outlet also dismissed the idea that Jack after-all is Renegade Marine Morgan.

Meanwhile, Design&Trend also included in their article that the succeeding episode will feature some past and present events. This part of the story is from the conversation of Law and Duke Nekomamushi.

"This week's chapter, like the last few chapters, will bounce between flashback and present time. During present time, we will see Law interact with Duke Nekomamushi," scooped by Design&Trend. "Nekomamushi will then tell his flashback story to Law, the same way Duke Inuarashi did with the Strawhats. After all, the King of Day fell asleep in the last chapter, so who else to tell the story than the King of Night."

Catch the release of "One Piece" Chapter 810 on Thurs. Dec. 17.
