The latest "One Piece" Episode 782 spoilers reveal that there will be a big showdown between Luffy and All-Hunt Grount who is well-known in the pirate world for his mechanical and very powerful left arm. It appears that he will try to use his left arm to bring down Luffy. But will he be able to?

There were also speculations that "One Piece" Episode 782 will be the culmination of the Marine Rookie Arc. Previous reports claimed that this arc consists of just three episodes and the upcoming one is the last. That means the new arc that many fans are eagerly waiting for might start next week.

This is the Whole Cake Island Arc where Sanji and the Straw Hat Pirates will try to rescue Sanji from his wedding to Lady Pudding. Previous "One Piece" Episode 782 spoilers have indicated that the Marine Rookie Arc will serve as a lead-in to the WCI arc, and it seems they are proven true. It is also called the Sanji Retrieval Arc.

The title of the upcoming "One Piece" Episode 782 is "Fist of the Devil - Showdown! Luffy vs. Grount." It can be recalled that Luffy has already defeated Grount in Episode 781. Some spoilers for this upcoming episode reveal that the two will engage in a battle again. This time, their fight will be more intense.

The teaser trailer of "One Piece" Episode 782 shows Grount recalling the former Admiral Aokiji. Luffy has already encountered this character in the previous Water 7 arc. It is not certain how remembering the memory of this former admiral will affect Grount in his upcoming fight against Luffy.

After "One Piece" Episode 782, the next episode will dwell on Sanji's wedding to Lady Pudding. Some spoilers suggest that its title will be "Sanji Return Home - To Big Mom's Territory!" It seems that the show will see Sanji's return instead of just concentrating on the shenanigans of Luffy and The Straw Hat Pirates.
