Her character is described as an ethereal beauty with the pristine manners of a Gotham debutante, reported Entertainment Weekly.
Silver St Cloud has been in "Batman" comics since the 1970s, dating back to when she made her debut in Detective Comics #470 as a love interest for the Caped Crusader.
St Cloud eventually becomes one of the few to discover Batman's hidden identity, before the two are eventually pushed apart because of Wayne's secret life as a costume-wearing vigilante.
