'One Piece' 837 spoilers, rumors: Luffy to battle against Cracker; Nami to save Carrot and Chopper

A battle between Luffy and Cracker is speculated to happen in "One Piece" 837, while Nami will go head-to-head with Brulee in order to save Carrot and Chopper.
Fans of the manga are getting to discover the love affairs of Big Mom with the appearance of Pound. In the previous chapter, Pound is revealed to be the father of Lola and Chiffon and he seems to be sincere in wanting to get to know his daughters.
As he is being pursued by Cracker, Luffy defends Pound, which earns the ire of Cracker. Cracker has been described to be vicious and powerful, but Luffy is also known not to back up from a fight. While it looks like there is no way he can defeat Cracker, some suggest Luffy will awaken more of his powers.
As the manga's main protagonist, Luffy is expected to defeat all opponents no matter how strong and powerful they may seem. As his opponents grow stronger, viewers and readers get more excited to see what happens when he reaches the Perfection of Devil Fruits.
However, Pound is also seen suggesting Cracker could be his son and a father-and-son reunion may be witnessed in the next chapter.
Meanwhile, Carrot and Chopper are still trapped inside Brulee's magical mirror and, while Luffy is busy with Cracker, Nami might have to save their two friends by herself instead. Lola has given her a Vivre Card, which was shown to bring fear and cause Homies to concede. It suggests that the Vivre Card will help them get through the Seducing Woods, but it could also help in getting Carrot and Chopper out of the mirror.
With Pound by their side and some of Big Mom's children also coming to their aid, rescuing Sanji might happen soon.
