What's the name of the movie where a young man finds this item that attaches itself to him and somehow turns him into a monster? I think it is from the '80's or '90's.
Other people are looking for that same item and they can turn into monsters, too. The movie goes on and the young man eventually kills the other guys in their monster form and the last bad guy transforms into the biggest monster of all and was killed by the young man in monster form, too.
There was this one part where they thought they had killed him but he emerged from another monster's belly by cutting his belly with a blade on his elbow.
Was it called Magiver?
