Totally Vanitas, in Birth by Sleep is enough said how much force he uses.

I'm not picking until I get more answers.

Vanitas.

I got one more, couldn't wait any longer. XD

XD.

Anyway, how would they fight without keyblades? Struggle Bats? Dream Weapons?

I was thinking Struggle Bats...or just hand to hand. XD

Hand to hand, Aqua would be screwed XD

I dunno, she can still power up her hands with that kick ass magic of hers. She might stand a chance. =/ We'll never know, unless they get put into Super Smash Bros.

Yeah.

roxas is the nobody of sora. who needs a stinking keyblade when you have magic or nobody powers.

There aren't any special powers you get when you're a Nobody, other than being unaffected by anything bad that happens...but he is, obviously...he's not a Nobody since he has a Heart...but he would kick ass anyway. XD

Aqua or Vanitas would win. Most likely Aqua though because of her superior magic skill coupled with her flexibilty and agility. Shes already easily beaten Vanitas before, but of course he was holding back. Dunno, between the two of them it would be a draw. Roxas doesn't stand a chance against either, he has only half the power of Sora, and also Aqua and Vanitas far surpass anything Sora or Roxas has achieved. They are keyblade master level so they pawn.

HALF? He has VEN'S HEART! And Xion's Keyblade! He Has Sora stuff, Ven stuff, and Xion Stuff, so he has his stuff too, which makes four. -_-' Vanitas has Ven and Darkness...and Aqua has KICK-MOTHERFOOKING-ASS! XD
