I'm looking for an explanation as to why Zidane has a tail. I've only just begun the game, so if it's explained later then I suppose I'm a bit premature in asking. The only explanation I have for it is the presence of other "demi-humans" located within the world and him being just another one of those demi-humans. In Dissidia, Ultimecia refers to him as "monkey boy" on one occasion, so I suppose he's half human and half monkey?

Anyone care to give me a better explanation? I know FFIX is a throwback to older FF games, but I don't recall any main character having obvious animal appendages before in previous games.

I briefly looked at the three pages of threads to see if there was a post about his tail, but I didn't see any so I apologize if there already is one.
