It looks stupid. I can't say much more than that. I just can't stand looking at it so it gets the bench. If it wasn't for having to recruit it to get to the other continent I would love it to rot in its' swamp.
Well, plot-wise, if you had change Quina's parts for some random NPC or other character it would have been the same. It only adds comical relief, nothing else. And Zidane does that better (certainly more subtle and less goofy). Plus, a fork? Really? Hadn't Final Fantasy had enough stupid weapons already?!?
The game wouldn't have been the same for me without Quina.I might be in the minority, but Quina is one of my favorite characters to use in battle.
As far as utility goes, the blue magic was great. I just found Quina annoying and silly looking though and the blue magic was definitely not necessary to have in the party. Much like Gau who I dislike as much as Quina. From the first time I met the little bugger and he's all "Awuu me Gau" or whatever. I was done.
