The upcoming chapter 857 of "One Piece" is alleged to feature Luffy's attempt to stop Sanji and Pudding's wedding. However, it is said that the captain of the Straw Hat Pirates will not be alone in wreaking havoc at his friend's wedding as it is suspected that the next installment of the manga series will also feature the return of the Straw Hat Grand Fleet.

Reports claim that Luffy may finally win his fight against Big Mom in "One Piece" chapter 857 as it is possible for the upcoming chapter to feature the return of the Straw Hat Grand Fleet. To the uninitiated, the Straw Hat Grand Fleet is composed of the seven strongest organizations in the "One Piece" universe, namely, Yonta Maria Grand Fleet, Tonta Corps, New Giant Warrior Pirates, Barto Club, XXX Gym Martial Arts Alliance, Happo Navy, and the Beautiful Pirate crew.

With the return of the Straw Hat Grand Fleet, it goes without saying that Cavendish, Bartolomeo, Sai, Ideo, Leo, Hajrudin, and Orlumbus are also returning. As all the members of the Straw Hat Grand Fleet consider Luffy as their leader, it goes without saying that they will help him in his quest. Hence, it is believed that Big Mom will finally be defeated.

While the return of the Straw Hat Grand Fleet is nothing short of exciting, unfortunately, it is not yet confirmed whether it will really be the case. However, whether the group is really returning in the next chapter or not, it is alleged that "One Piece" chapter 857 will feature the Whole Cake Island as a battlefield.

According to other sources, Sanji's family, the Vinsmokes, may finally form an alliance with the Straw Hat Pirates and will fight Big Mom and her allies as one. After all, it is said that the Vinsmokes already have a gut feel that Big Mom and her allies will kill them on Sanji's wedding day. Hence, all hell will break loose in the upcoming installment of the popular manga series.

Will the Straw Hat Grand Fleet really return? Can Big Mom finally be defeated?
