Olimar is a beast because his aerials have priority and his grab is insane. I've been trying to mess around with Fox, but he's been nerfed to badly to make any safe approaches on opponents. Shine spiking is a lot harder to hit also.

I really like Toon Link though. His short hop double bair is really good. Out of PT, I think Ivysaur has the most potential, although Squirtle is my best.
