Heroes are often defined and made what they are by two things: the villains they face and the burdens they carry. Superman carries the burden of fear and anxiety, living a life afraid of breaking something, of killing someone should be be careless with his power. In some ways, Spider-man fought off depression after the death of his Uncle Ben by turning to crime-fighting. Batman turned his fear and anxiety into a weapon in his personal war, fueling his lone crusade against crime. However, in very few heroes is the relationship between burden and heroism as blatant and as prominent as in Tony Stark, the Iron Man.
