Laserblast

A teenage loner discovers an alien laser cannon in the desert, which wreaks havoc on his life and the lives of those around him. As Billy's body begins to mutate into a grotesque green-skinned creature, he goes on a violent rampage, leaving destruction and death in his wake. The film's stop motion animation is one of its few redeeming qualities, but overall it has been panned for its convoluted plot, poor acting, and lack of coherence. Ultimately, Billy's transformation leads to his downfall, as he becomes the very monster he was meant to destroy.
