Hi looking for a movie wher a boy finds an alien suite. I think I start with a fish alien dies with the device in his hands and the boys falls on it. As memory recalles he got blades coming out of his elbows and the inactive souite looks like a pearl. Can't remember the title and it was not starkid

Perhaps Laserblast.

Or possibly Guyver (http://www.imdb.com/title/tt0101988/)
