Marlene is the daughter of archaeologist Peter Alraune Sr. and the brother of Peter Alraune Jr. She is first seen in
Sudan with her father when he is killed by the mercenary
Raoul Bushman. Another mercenary named
Marc Spector saves Marlene's life, but Bushman ends up leaving Spector to die in the desert. Peter Alraune's workers bring Spector's inert body to the tomb of
Pharaoh Seti III. Spector miraculously revives and he and Marlene return to the United States where he became the crimefighter Moon Knight. Marlene began to fall in love with Spector, who also used the alias of Steven Grant and Jake Lockley. When Moon Knight is called back to Sudan due to a vision of Khonshu, Marlene stated that she would leave Marc if he left. As a result, Marlene moves out of their
Long Island apartment. Enrolling in a university to study work, Marlene moves in with her husband Eric Fontaine. She graduates from the university and becomes a researcher at Seaview Research Hospital. Marlene and Eric later separate, with Marlene returning to Marc Spector's side. After a while, both of them went their separate ways as Marc Spector's lifestyle was starting to endanger Marlene. Some time later, Moon Knight's Jake Lockley persona has a child named Diatrice with Marlene. Moon Knight's other personalities are unaware of this until Bushman and Sun King attack Marlene's house, where the truth is revealed to them. ==Powers and abilities==
