Iron Man

When billionaire industrialist Tony Stark was captured by Asian terrorists, and ordered to make weapons for them to help overthrow the United States, he instead made a suit of armor to help him escape. Upon returning home, Tony began construction on a new suit of armor, and now saves the less fortunate as the Invincible Iron Man!

To date, Iron Man has over 43 suits of armor.
