'One Piece' chapters 859, 860 spoilers: Bege reveals his battle plan to defeat Big Mom

Chapters 859 and 860 continue the Whole Cake Island story arc in "One Piece," with the wedding between Sanji and Lady Pudding, one of the daughters of Big Mom, featured in both.

Luffy and Bege finally agreed to work together to stop this from happening — the former in order to attempt to rescue his friend, and the latter to wrest power from Big Mom. Belge observed that she gets touchy about a certain portrait, so they will use this to distract her. They will then use that as a diversion so that they can shoot special poison rockets prepared by Caesar Clown/Gangster Gangstino to weaken Big Mom, thereby giving them the opportunity to assassinate her. However, they will only have a four-second window to pull this off, which can be tricky given that Big Mom also has her own pirates.

Luffy and the Straw Hats will be responsible for rescuing the Vinsmokes, while Bege and his team will carry out the actual assassination. Once their task is completed, they will then use the mirror to get out of the island.

However, Luffy is not known to handle plans very well, so it is highly possible that their plot to assassinate Big Mom might not work as well as they want it to. However, the Straw Hats are known for their improvisation skills, so it is possible that they will be able to pull off saving Sanji and the rest of the Vinsmoke family. The assassination attempt itself will be a challenge because Big Mom is known to be very resilient to damage. However, speculations are suggesting that the portrait has an effect on her abilities, so damaging this may also lead to her demise.

Pudding, meanwhile, is planning to wipe the memories of at least some of the attendees of her wedding so that she can be a "good child" again. She is also expected to shoot Sanji in the middle of the ceremony.
