I'm trying to find a title for a movie I saw when I was younger -- I'm pretty sure it was filmed in the 1980's and the star is a 20-something male that becomes a superhero because of some sort of alien-symbiotic suit that either comes out of the back of his neck or from his mouth, it springs out in tentical-like fashion to cover, and consume his whole body -- after the suit covers him, he then begets great strength, speed, and agility. I realize this is a very vague description, the only other thing I can remember is at the end he fights this other alien that is probably 10 times his size, the alien had assumed the superhero to be dead -- then the hero stated that he was "rejected from hell" when the enemy stated that he thought the hero was dead. This is bugging me to death! If anyone can remember what this movie is called please inform me!

Sounds like Guyver (http://www.imdb.com/title/tt0101988/)

Pretty sure it's "The Guyver" with Jake Armstrong and Mark Hamill; It has a sequel too!
