Baroness Blood was an ace Nazi fighter pilot with a sadistic personality. Her plane was shot down by Black Angel during World War II, but she survived the crash and continued to plague the hero as a Nazi commander. At one point, Blood captured the Black Prince, a heroic RAF pilot who had fallen in love with Black Angel, who was also being held captive. Blood insisted that the Black Prince marry her and explained to him that he would love her, if she had to torture him, in order to make that happen.
