Actually, it seems more likely that Kuja has the tail the entire game. He just keeps it hidden. This is suggested by the following segment of dialogue:Originally Posted by Mercen-X
Um . . . dude . . . you can't see Kuja's tail during the story. He removed so he wouldn't be like the others. It only grows back when he finally achieves Trance.
The fact remains, of course, that the player wouldn't be aware of this fact until the above dialogue takes place.Zidane: Alike? I've never met anyone like me...
Garland: You judge by appearances. I mean someone with a soul similar
to yours. The one I sent to Gaia might also be called your brother... And
his name is Kuja.
Zidane: Kuja!? He's a Genome!? Impossible! He doesn't even have a tail...
Garland: He is only hiding it. He denies his own identity. He rejects
the meaning of his existence and tries to assert his own individuality.
Don't you see resemblance?
