Heavy Metal (1981)

As Loc-Nar, a pulsating green orb from deep space, finds its way into the Earth, a multifaceted story of cosmic malice that transcends the strict boundaries of our universe unfolds. No one knows the origin of the floating crystalline sphere; however, all those who have encountered mystical Loc-Nar--men and women across galaxies and dimensions--have fallen prey to the corrosive power of the ancient, green-hued entity. As the tentacles of the parasitic intergalactic force spread across time and space, the question remains. Who can stand in the way of pure evil? Will a noble defender answer humankind's urgent call for help?
