Not just a costume, but a functioning apparatus that could perform the miracles the spectacular marvel in the movie does? Well, not really. We’ll have to pass on antigravity tech and jets blowing out the bottoms of our feet that are hot enough to roast our tootsies like marshmallows — never mind that the suit clearly breaks the first law of thermodynamics, creating energy for free.
