Almost sounds like Spawn: In the Demon's Hand (Sega Dreamcast), except that ad doesn't have a shirtless biker. It DOES have the Violator (who has insect eyes) tons of other demons, fire AND a red head with 2 guns.
edit: The human violator does look like a biker, and his shirt is pulled up showing his belly because he is so obese
further edit: eff it, was this it?
