|Ethan Clark Gallery|
Ethan Clark is a Gotham City businessman.
Clark was an estate banker, rarely taking financial risks. To shield himself from any mistakes, he turned to the mystic Nostromos. Several revelations came true: a cave-in at the Zanza mine, a fire at the Karobi oil field, and lastly Nostromos advised against going on a gambling cruise—rightly so, because the ship sank under suspicious circumstances. His daughter Lisa was a vocal critic of his trust in Nostromos, and was appalled when her father inducted her friend Bruce Wayne into the society. On their way to their first meeting, he informed Bruce of Nostromos' greatest prophecy yet: economic downfall in the West. But at the advice of Nostromos, they had set up a superfund.
That night, Nostromos convinced him that the downfall was near; the next morning the first thing he did was put all his money into the superfund. But Nostromos was not fully pleased: the entire superfund would have to be converted into gold bullion. When Clark refused (stating that at least the Brotherhood should be notified), Nostromos showed his true self: he would kill Lisa if he didn't sign the papers. When he did, Lucas tied him up so he would die when the building exploded.
Batman broke in. After a fight in which he defeated both Nostromos and Lucas, Batman got Lisa and Ethan to safety.
