Been trying to think of the name of an old movie I watched when I was a little kid but with no luck, I dont remember much but what I do remember was a young guy who finds a small box or maybe it was a briefcase with some sort of alien artifact inside which attaches itself to the back of his neck and shoots out forming a blue power suit of some kind.
 
I think the bad guys also have the ability to transform too but their after the kid because his suit is something unique/prototype maybe.. something like that.
At the end I'm pretty sure I remember the main bad guy turns into a giant creature before the two of them fight it out?
 
Anyone know what I'm talking about?

Nope thats not it.....

i cannot fucking believe that i know this

Nope... a lot older than that.

Do you know how old it is?

Wow I thought it was star kid too...

my fav part is when he eats the cheeseburger and the suit makes it into this weird ball and feeds it to him. I can verify that even though he says its gross, cheeseburger is actually still very tasty in ball form

Nah I really dont remember, im thinking maybe 80's..

wish I had more info but I dont remember enough about the movie to give any more details out.
