From the earliest days of his appearances in Marvel Comics' 'Tales of Suspense,' Tony Stark has always been modeled after aviator/inventor/industrialist Howard Hughes. With 'Iron Man 3,' Stark assumes a new dimension of Hughes' persona: that of the paranoid shut-in who, in his later years, became notorious for roaming his private floor of the Desert Inn Hotel in Las Vegas, freaking out about invisible germs and collecting jars of his own urine. 'Iron Man 3's' Tony Stark, played once again by the inimitable Robert Downey Jr.isn't quite that bad, but he's getting there.
After the events chronicled in 'The Avengers,' where Manhattan was nearly leveled by invading aliens and Tony himself was almost killed, he's become obsessed with upgrading his armor -- leaping all the way from the Mark VII to the Mark 42 in a matter of months. When anyone mentions New York or aliens, Tony gets panic attacks. There's a reason Daredevil, not Iron Man, is the Marvel hero known as "The Man Without Fear." Poor Tony is terrified.
