Before I saw any dialogue in the game, I thought he was a she, then once the dialogue said he was infact a he, I was surprised, but took in the information for what it is. He does indeed look like a girl, and dresses like one, and acts feminine like one, but we all know he's a girl. Some people (including myself) like to bash Kuja and call him a girl, just because he looks like it and and I don't like him. It's not as though I've mistaken his gender (besides the first time I saw him, with no dialogue), I know that he's a dude but I just like calling him a girl because he might as well be, from his appearance.
