Sophia Santos was an Italian terrorist who started a criminal campaing in Gotham City under the masked identity of Thanatos. She also used her civilian alias of Lina Muller, a gorgeous reporter, to attract some of Gotham's wealthiest men. Bruce Wayne became one of her targets and she took him to the Gotham Isle, where Bruce was forced to gamble thanks to a machine created by Amos Fortune. Unfortunately for Santos, Bruce realized there was something wrong with his own behaviour and after capturing Amos, he investigated "Lina" and found her true identity while also deduced her gambling addiction.
Batman lured Thanatos to a trap on Gotham Isle, where she was defeated and her gang captured. The Gotham City Police Department arrived soon enough to capture her and put an end to her criminal career.
