Im looking for a 70's or 80's animation, all I remember is a boy who some how meets as an old man in the future, and he has a metal plate on his head, later you find out the old man is him, then the boy has a accident, and that's how he gets a metal plate on his head.
I also remember something about small robots that could hear every thing in the universe.
Can any one help?
