Erm.. in pokemon, Fire > Ice.  It melts it you see.  Also, wee could go into vegitation :D

Also, I always thought it was wind, fire, water, earth.  Thunder could go in there in RPGs.  Sometimes they'll have electrical enemies weak to water, as well as usually thunder, but ti is almost always water is weak to thunder as well.  I think wee should have wind as weak to thunder, sort of like in Pokemon.  Funny thing, I was listening to Elements by Stratovarius earlier today.
