Is Zod anything besides a character in Superman?

I know he's a Character from Superman, but is he anything else? The Disturbed song Meaning of Life says "Give in, Give in to Zod, Give in." and he's featured in the Aqua Unit Patrol Squad 1 episode "Wi-Tri." Is he biblical or anything, or just from Superman?|||He was created as an antagonist to Superman which first appeared in Adventure Comics #283 April 1961...|||I think his only extstence is due to Superman series.
