'Legend' (1985)

Creepy features: The aptly named Lord of Darkness is truly terrifying. He is the ultimate devilish demon with enormous horns, whose quest is to create eternal night by destroying the last of the unicorns. His skin-crawling voice saying "There shall never be another dawn" sends chills down the spine.

Friend or foe? Foe! He is the creature who encompasses everything feared about hell.
