@AGOG - wow that is super long post..
But i still don't think anyone mention above will join the SHs..It'll be a new one
Super long posts are typically the better ones, they seem to contain a lot of heart in the argument.
I agree with @AGOG 's post pretty much, but I also think that Oda may not do that and just have her as a recurring side character like Bon Clay. But you never know, I mean, it may turn out that Oda was planning to have Perona join all along, he's the author, he'll come up with something good.
I don't think it can be denied at this point that she will have a future involvement of some kind. I can almost see her being roped into a huge chain of events. She obviously strives for companions. At least in the anime it showed that she was determined to keep that company around. I think she just has an odd an spoiled way of showing it.
