Kull the Conqueror (1997)

A barbarian named Kull becomes ruler after defeating the old king in battle, thus receiving his crown. But direct heirs of the king, trying to topple Kull and regain the throne, bring an old witch queen Akivasha back to life. Their plan backfires, however, as Akivasha plans to have her demon lords rule the kingdom alone. The only thing that can stop her is the breath of the god Volka, and Kull.
