That sounds more like something up Marluxia's alley.
Well that's IF there's is a level system like the drive forms.
It MIGHT happen. That, or Xehanort (Org. 13) is a CLONE of Terra.
Or maybe she cries tears that affect the opponent in whatever her element affects others. She could be some kind of emo.
If she had that power, why would she be gone in KH2?
Meh, they'll probably use the more powerful attacks near the end of the game.
Well since we don't know his name (yet) we'll have to wait for BBS.
If it's poison, maybe she accidentally "killed" herself with it.
Maybe they're poison needles gloves.
Maybe you can do that in the overworld.:D
Well if you have to kill her because she betray the Org., that'd be an ineffective element.
Maybe she uses grenades.
I particularly hope for Ars Arcanum.
I still say her bodily functions could be weapons.
I'm still going with poison.
Do you think they'll use the keyblade attacks like Ars Arcanum in Birth By Sleep?
Well she's new, so she might learn new techniques later in the game.
Though I can't believe people didn't think about this.
Number 14 probably IS a weapon. If her element was poison she could cry poison gas or have poison barf.:D
Maybe her element is poison and she has the power to cry poison gas, like that character in "Heroes".
