Ultimate Iron Man (Antonio "Tony" Stark), is the Ultimate Marvel version of the fictional superhero Iron Man that first appeared in the fourth issue of Ultimate Marvel Team-Up, written by Brian Michael Bendis and drawn by Mike Allred. He later appeared in the Ultimates and often appears in the same titles they do. In the Ultimate Universe, the character is a wealthy business tycoon and inventor who created the Iron Man power armor. Like his mainstream counterpart, he has a drinking problem and life-threatening affliction; in this case an inoperable brain tumor. With a life expectancy anywhere between six months and five years, he chose to become a philanthropist and superhero.
