Entertainment Weekly describes St. Cloud as "an ethereal beauty with the pristine manners of a Gotham debutante." Like Bruce, St. Cloud lost her parents as a young age, which sets up an instant bond between the two characters. However, where Bruce's tragedy puts him on the path to justice, St. Cloud has decidedly darker intentions.
Bruce will meet St. Cloud through her uncle Theo Galavan, a billionaire philanthropist and mayoral candidate. In much the same way he finds a kindred spirit in St. Cloud, he will find a father figure in Galavan.
