Uh...Kuja isn't a Red Mage. He doesn't have a sword, the spell Haste, or feathered hat. Though I'd have to be that, if it were available.

Blue Mage would be nice, though I'm not fond of eating my enemies to gain their powers...especially given what some of them look like. But I suppose it's a better alternative to getting hit by whatever attack I want to learn...

White Mages are awesome. Too bad Eiko couldn't have a cat hood like all the best White Mages...
