Actually I am not really sure about the title because technically Iron man does not have any super powers. He is a really cool and a very rich scientist. But anyways, that still doesn't change the fact that he is the bravest and coolest of all the superheroes till now.

I mean look at spiderman, batman or superman for that matter. None of them ever wanted anyone to know their true identity. I think it's because they were too scared to know what people might think about them or how they will judge them. But Iron man is way too confident and really doesn't care. So he has never hidden his true identity.Hahahaahhahahahahaha
