Hi y'all, I have a theory here. I was reading a summary of a translation for the new chapter, and I read about this penguin who kicked all the zombies who were attacking Nami, and told them that they should never hurt a lady… and that if they wanted to fight they should fight him.
Now this is clearly Sanji's personality. And we know that Ryuma seems to have Brook's personality. So, since Sanji disappeared last chapter, something could've happened to him. Maybe the undead people and creations all have someone else's spirit, and this penguin has Sanji's, and Ryuma has Brook's. Now of course they wouldn't 'steal' their soul or personality, since Brook had his own personality, and Sanji probably will still have his, but I wouldn't be surprised if the "negative ghosts" allowed Perona to give dead things the "spirits" of others, or something.
It's a bit early but that's why I wanted to share it before it was revealed. What do you think? Could we see a copy of Luffy, Franky, etc? Who gets these spirits and how will it affect anything? Or is it a bunch of balony?
