An iron man suit is possible. In fact they r making a real one at the moment. Agent Phil coulsen was promoting it. But after calculations a real iron man suit that's fully functional like the movie one would cost approximately 5mill and up
They'd definitely be onto something there if they made it look slightly more Iron Man-esque or instead of the streamers could add a big Superman cape..
Sorry just thought id show... thought it would relate to all the iron man armors made...and if it would ever be possible to have an actual iron man costume rigged up to it be it foam or something... anything seems possible here at RPF...:lol
