Well, working from the movies, he is mostly typed as ENTP or ENTJ... although I rather think he is a P (racing the car in the second film, the birthday party, being VERY late for his flight in the first film... and of course annoying Rhodey and Pepper, who both seem to be J's...) I even read somewhere, that he is the perfect ENTP stereotype... which would explain why I can identify with him for about 60-80%...Well, hello there. And welcome
I like ironman too. I wonder if he is an ENTP. I've always assumed that he is.
