Blue magic is great, apart for that one spell that blows you up in order to deal a fraction of the enemy's total HP.

The thought of consuming one's enemies to gain their powers is pretty disgusting when some of those enemies are Marlboros, but I'd probably be more worried about the power generators and dark matters.

Then again, the Devour command already exists...

...I've come to realize that FFVIII is a pretty damn gross game.
