About 70% of the time I play as Fox. He's quick, and has great up smash attacks. The only downside I feel playing Fox is that he falls like a rock.

If I'm not playing Fox, I spend about 20% of my time with Jigglypuff just because it pisses my friends off and rest is so much fun. Finally, I spend the last 10% of my playtime with Pichu. Yes, he flies way too far, and he hurts himself, but he's so dang fast I do a lot of fleeing and his ->A smash attack is great. Headbutt is fun too. You just have to know when to run with Pichu, which he is pretty dang good at.

Finally, even though I'm at 100%, there are occassional times when I'll use Kirby just because his taunt annoys the living daylights out of everyone.
