STILL NOT OVERPOWERED
Jiggles doesn't break the damn metagame like, say, Meta Knight. Obviously she's damn good, but I wouldn't go as far as to say overpowered.
Ehhh... My knowledge of 64 isn't enough for me to judge if Pikachu is overpowered or not (Isai is overpowered, though). But in the realms of Melee and Brawl, yes, I believe Meta is the only broken bastard.
Tier? Isai shits on tiers and then commands Meta Knight to throw it at Sakurai. You cannot grasp the true form of Isai's godliness!
EDIT: GOD DAMNIT I'M OFF TOPIC AGAIN Dx! Pokemon trainer talk pllll00000xxxxx?!?!?
