Turn of the century Occult Hero Iron Man, aka Tony Stark.
For the interested:
The armor includes pieces from the Armor of Achilles, Weyland's Armor for Beowulf, the Kavacha (Armor of Karna), and the Shield of Lancelot. It is inscribed with many magical sigils and invested with spirits of the air and earth. The crystal that activates the armor draws its energy from Stark's own heart, which he had surgically (and mystically, of course) removed and sealed within.
His motto is 'Lux et Veritas', 'Light and Truth'.
Stark is a romantic in the truest sense and he sees himself as a modern St. George, battling dragons. Unfortunately, his bizarre crusade against evil has led to him being dubbed the "Iron Quixote" by many of the newspapers he doesn't have a controlling interest in.
He is a powerful Freemason of a very high degree, and a confirmed believer in the extra-medicinal effects of opium tincture.
