What about those damn Flans (FF4 variety)? "Ooooh, look at me, I have 1000 more HP than that other flan beside me because I'm RED instead of GREEN!" Plus they don't give you any experience... And normal attacks would do 1-5 HP damage..
They each had different names in FF4 based on color, but I can't think of any of them at this point. Except Pudding, which was the black one (I think..)
