This song to me is about a rebellion. Perhaps a rebellion against the evil things in the world people just accept. But in the song he's helping to rebel against evil (after all, this song was made for ironman 3) "off in the distance, there is a resistance, bubbling and festering." So that means a rebellion is starting."a man on a mission, changing the vision, I was never welcome here" so he is basically saying that he wants to change the world for the better and defeat evils, but people are basically slaves and too afraid to stand up for what they think is right, so they just go with it. However, since he stands out and won't put up with wrongdoing, people look at him as an outsider and they look down on him for standing up against evil.
