Sounds like this tbh. He might be the new CP-0 head, which is frankly surprising if true because I wouldn't have expected him to be the strongest of them. Would have more expected the 3 currently in Wano to be stronger.
How has this ruined Sanji’s development ? Vinsmokes hate him because his “mentality” is weak. Not his strength or abilities. He oneshotted Yonji in WCI, they dont care that hes physically strong now. They hate his kindness and caring attitude. They hate that he cooks. Basically everything that Sanji got from Sora and Zeff….
Sanji developing his own natural exoskeleton doesnt ruin him. Only the RS did, since that was using the tech of the family he hates.
That's not even the point of the argument, lol. You're saying that Sanji received a PU because he can't beat Queen but when and if Zoro will get it, you'll say it's for Kaido and Zoro could've defeated him anyway.
