"One Piece 839" may feature the battle between Luffy and Charlotte Cracker that is more likely to get tougher as Luffy discovers that his enemy is stronger than he thought, even activating his Gear 4th does not seem to be enough. Luffy may need to activate his Gear 5th or an awakening, since he is struggling with the commander and his biscuit warriors.
The "One Piece 839" possibility could lead to Luffy growing weary of the biscuit warriors without even hitting Cracker himself and his Gear 4th may reach its limit. A similar incident happened when Luffy fought Doflamingo and his Gear 4th vanished after reaching a time limit.
"One Piece 839" release is going to be delayed to a week from now. The 'One Piece' team is currently on a break so there is not going to be a new chapter for a while. However, this also means that there will be a lot of spoilers to look out for, Bitbag reported.
Meanwhile, Big Mom's castle is busy with preparations for the pre-wedding events and the customary exchange of engagement gifts. Vinsmokes Nichiji and Ichiji arrive that may lead to a battle with Luffy in "One Piece 839."
The "One Piece 839" Straw Hats has to prepare for the Vinsmokes as they are the elemental types. Reiji uses poison, while the two Vinsmokes use electricity.
"One Piece 839" may also see Brook in a major role since Big Mom's Soul--Soul Devil Fruit does not have any effect on him. Brook may also be featured in the chapters to come. Additionally, he may have some connection with the Vinsmokes who may have assassinated the Rumbar Pirates.
"One Piece 839" will also give a closer look of Brulee's Mirror World, which is actually a vast network of pathways connecting every mirror in the entire cake island. Rumors are that Luffy and Nami may take advantage of the network of mirrors when they rescue Sanji, GamenGuide reported.
"One Piece 839" network of mirrors could grant anyone access to anywhere in the island that has mirrors in it. Nami, Chopper, and Carrot may be the ones to save Sanji, with Luffy's hands full with Cracker's "Thousand Arms" or biscuit soldiers.
