I don't think she's gonna be a "real" villian. I mean Kuja was a rival and a villian, same with seifer, but Le Blanc she jsut probably wants to get in the way.

Hopefully she will have a good reason for being a villian, and not just some lame excuse. Does anyone know? Or is it just that she's in a rival sphere group?
She probably wants them because she thinks that they'd make a good mirror or something, so she can admirer her sel all the time. That's the immpresion she gives me ^.^
