This week, the hit pirate manga "One Piece" continues. Speculations suggest that aside from unraveling mysteries about Sanji's family, chapter 841 will shift back to the fight between Luffy and Cracker.

The fight in the Seducing Woods is reportedly reaching its climax, as both fighters are readying their most powerful skills and techniques.

Cracker, one of the top executives of the Yonkou Big Mom, has been revealed to have a technique under his sleeves. It even seemed that the tenth son of the Yonkou is slowly overpowering the captain of the Straw Hat Pirates.

According to industry followers, Luffy may be compelled to use some hidden skills in order to fight his way out. Mobipicker suggests that the Straw Hat Pirates captain will then draw out a much more powerful technique, Gear 5th. Although there are still no indications that Luffy has that much-hidden power, it is highly possible that his skill is not topping out only at Gear 4th since he has trained extensively for at least two years.

Meanwhile, aside from Luffy's fight, the other focus of the current arc is the background on Sanji's family. It has been revealed in the past chapter that Sanji's father has worked before with the mad scientist Dr. Vegapunk and has already proceeded deeply into the realm of human clone experimentation. This enabled the Vinsmoke family to create their own army of cloned workers. It is also confirmed that much of the Germa 66 army stemmed from the research.

With Sanji's arranged marriage happening soon, it is said that Sanji will have to develop more skills in order to escape from his family, or else, he would need some outside help — more likely from his sister — in order to meet with Luffy and the rest of his friends and to escape the Yonkou pirate Big Mom.

"One Piece" chapter 841 is scheduled to be released later this week.
