The Straw Hat pirate leader, Monkey D. Luffy, was able to take down one of the strongest Sweet Commander of Big Mom, Charlotte Katakuri.

However, the fight is far from over as "One Piece" chapter 899 is likely to introduce a new adversary for the Straw Hat pirates. Fans are also worried about Sanji and Luffy, who are struggling to get aboard the Thousand Sunny as the Big Mom pirates launched an all-out attack against their enemies.

The latest scoop from the One Piece Forum does not bode well for the Straw Hat pirates. It is rumored that Big Mom will send in one of her children to capture Luffy. After the fall of Katakuri, it looks like the fans will see another intense battle as a female member of the Charlotte family unleashes her fury.

However, the exact identity of this new Sweet Commander is still unknown, although the plot rumors suggest that the new enemy has mastered the Geppo technique, making her just as dangerous as her brother Katakuri.

The fact that the rumored new antagonist in "One Piece" chapter 899 is a woman automatically turns the tide to her favor. This is because Sanji has sworn to his life that he will never hurt a woman, but his principles will be put into test as Big Mom's daughter threatens the lives of the Straw Hat pirates. At this point, Luffy is on his weakened state after using all of his power to fight Katakuri, and it is all up to Sanji to look after their leader. 

"One Piece" chapter 899 is also expected to feature the Germa pirates, and it is possible that the fans will see more of Sanji's relatives fighting the Big Mom pirates. The Vinsmoke clan entered the battle in aid of the Straw Hat pirates, completely turning their back on Big Mom. As the enemies send in troops to capture Sanji and Luffy, the Germa pirates will do everything they can so that the two will be able to return to the Thousand Sunny.

Possibly, the extent of the Vinsmoke family's power will be tested in "One Piece" chapter 899 as one of Big Mom's commanders challenges them in a fight. It is speculated that Daifuku will catch up on the Vinsmoke clan's ship, forcing Sanji and his family to deal with him before getting aboard the Thousand Sunny.

Nevertheless, this will be an opportunity for the fans to learn more about the powerful Germa pirates, as their previous appearances in the manga had shown little of their capabilities.

"One Piece" chapter 899 will be released later this week.
