I was fighting some random enemy that wouldn't die, and decided I wanted to be OP with Celes.
I have her double cast Meteor, and have Gogo mime that.
Now, before she can fire off the spell, the monster decides to be a douche and hit her with confusion. What does she do? She dual casts meteor on my party, of course. But that doesn't kill my party. No.
Gogo mimes what she did. He TOO casts meteor on my party, thus annihilating me.
I never used Gogo again for the rest of that play through.
