I absolutely LOVE super heroes. Finding out super hero personality types is awesome because if you find one that fits your personality type you feel a closer bond to that super hero, like you understand them better. For example: Spiderman, I believe, is an INTP. However, I have been discussing this with 2 of my friends (an INTP and an ENTP) and we haven't been able to find any ENFP super heroes. This isn't to say that there aren't any, we just can't think of any. If you can think of any please post their names and your reasons for ENFPing them. Or you can just say what any super hero's type is and why.
I love Captain America but I think he's an ISTJ. Not that being an ISTJ is a bad thing, I would just love being the same type as him.
The Best Of Luck!
