Floral Fallal, Machina Maw and Full Throttle all just seemed wholly unnecessary. Most people know X-2 isn't the hardest game around but even when it is challenging, I see no reason to waste your time zooming around the Garment Grid only to unlock this crap.
But if you did actually use them at some point, I'm curious as to when. Are they a good help against some bosses or whatever?
