Lady Satan, Golden Age heroine sketch card

Lady Satan is a non-superpowered heroine from The Golden Age who mysteriously transitioned into being a sorceress. In 1941, an unnamed young woman and her fiance were on a ship sunk by Nazis. The young woman survived, and became a costumed vigilante to avenge her fiance. After a few adventures, she disappeared from comics until 1946, when she resurfaced with black magic powers. No explanation was given as to how she attained those powers, but she used them to battle supernatural menaces.
