Sorry, I have to make another Perona post. Here's the thing about Perona. To support Perona, you have to assume that she'll have a flashback of some formative experience that will justify her allegiance to Moria, explain some deeper reason for her behavior, and cast her character in a new light that makes her a good fit for the Strawhat crew. Like, let's say that when she ate the Horo-Horo Fruit she couldn't control when her ghosts appeared. So she scared away her friends and was cast out by her family. Or even better, her negative spirits drove her family to suicide. Moria's pirate ship drifted ashore a la Jaguar D. Saul, with all of Moria's crew having been slaughtered by Kaidou, and the two grieving and traumatized people joined up. That would mean that she took refuge in the first "family" she could find, and she has been trying to fill the friendless void in her life with zombie companions. But the zombies are inadequate, so she doesn't love or respect them. There! Now she's a more sympathetic character who can learn what it really means to be nakama, etc., and that explanation only took a couple minutes to think up.
But there's no explanation I can think of that can simultaneously make her appear to be a sympathetic character while still fitting with what we already know about her, the biggest example being that her dream is to rule a kingdom with cute people turned into her zombie slaves. That is the dream of a shallow and selfish person, and I'm not sure there's any way around that.
This isn't to say, "Oh, you foolish Perona supporters," - I'm saying that there's weeks to go before the next issue comes out, and making a theory for Perona's past is a good challenge to take up. There are already pretty coherent theories out for how Jinbei and Hancock can develop as characters, so let's see one for Perona. That would be interesting, and it would make this thread more interesting.
