[Spank-A-Thon]

For sheer usefulness I'd be tempted to go with Hades (FFVII) cos of the status changes he could inflict (i.e. Stop on Ruby Weapon! ). But for total 'gobsmack-itude' without a doubt I go with Knights of the Round (VII). First time I saw that, especially given how time-consuming it is to obtain, I was literally sat there open-mouthed!

Edit: D'oh! Misread the title of the post! Anyway, as you can probably guess I go with FFVII.
