Villain Sue: Subverted. Whist the Men and Women in White are incredibly powerful, it's a ruse. They've been buffing themselves up to stand up to the canon characters, but the buffs wear off. Since nobody actually knows this, Sora and Co have no idea that if they went on the offensive they could take them out easier than they did Xehanort.
Crowning Moment of Awesome: Several, including scaling a Darkside and bashing it's face in with his hands, or punching the Erin directly in the face whilst she was strangling him.
