Fan Casting Amazing Man in DC Characters

Around the time of World War I, a young orphan is selected by the Council of Seven, high in the peaks of Tibet, to be taken under their wing and trained to perfection. The process takes many years, but by the time he is 25 years old, young John Amon has awesome strength and invulnerability as well as the ability to become a green mist. After passing a grueling series of tests, he is allowed to head back to America where he battles his greatest enemy the Great Question and fights crime as the aptly named Amazing Man.
