There's one occasion where Black Mages kick ass: When they happen to include Tsuyoshi Sekito and Kenichiro Fukui. Plus, the Black Mage does at least look totally awesome :)

Shame they didn't do such a good job of FF1's battle theme... Not nearly metal enough considering it was the first track of the first album. Ah well, Matoya's Cave was a kickass bluesy piece so it's forgiven.
