i think it could happen for example xion born from sora she considered male but she took kairi form instead but i always see her as a girl anyway that's why i think if xehanort put his heart inside female she'll become male in a way xehanortYou guys keep saying "in the end, they'll all be Xehanort", but how much?
To my knowledge, Nortification affects personality, ear pointiness, and hair/eye/skin color. I don't remember anything about a vessel's height and build changing to fit Xehanort's except KH2 Riku- who, I think we can all agree, was a special case.
What makes everyone think putting a male heart into a 'non-puppet' female body will turn it into a male body?
