Her playstyle already looks like it has the chance to be OP, have to wait and see. (Talk about balls to the wall) I like to think of her as Mrs. Freddy Krueger/Edward Scissorhands. A popular theory going around is that she's Amy only remodified. A lot can happen in 17 years, but...DAMN.
She's also the token Gothic Lolita as of now so Amy's chances either severely dropped, or there's more to it than that. She's supposedly 24, which doesn't match up with Amy's age, but heck magic swords have been proven to do anything so I wouldn't be the least bit surprised considering her father was jacked up with Soul Edge fumes. If it's in fact Amy it also increases Raphael's chances seeing as they both had the same play style more or less.
