The movie I'm trying to find the name for is a late 80's Sci-Fi action film that came out before Revenge of the Nerds 2 - so 85-87. It was in theaters during the summer.
In it there is this city that is under constant attack from a neighboring city or civilization of monsters. A young man volunteers to be turned into a cyborg to fight these monsters. He becomes a red and black leather covered cyborg able to change back and forth between human and cyborg.
Humans have been being captured and turned into slaves and mind controlled by a witch with an eye in the palm of her hand. At one point the hero is thrown or jumps into a pit only to transform and catch himself with a grappling hook from his cyborg arm, then jumping back out to kick butt.
Can anyone identify this movie?
