Iron Man super hero character (help)?

Today at school 2 of my friends and I did this thing called the Chalk Festival. It’s were 3-4 students from an art class can choose to be in it, where they get a picture and draw on a 8 by 8 square on the sidewalk with chalk. Well our theme is “around the world” and I’m the team captain even though I don’t want to be. I just have to because they can’t go to any mettings or anything because they both play sports. Well to get on to the subject the school want all of the team captains for the Chalk festival to write a statement, like why Iron has to do with the subject around the world. I really need help though because I don’t really know hhow it relates only that he can fly around the world… and ya. Please help I’ll give the best answer 5 stars. =]
I MADE A MISTAKE!! The theme is Art around the world. can you help me
