Jane

Jane is Twilight's sister. She died during The Black Plague and was reincarnated in the modern era as Anik Sarrazin. Anik is a member of an all girl pop-group named the Space Girls. Her stage name is Deep Space. She was later captured by Lilith and used to blackmail her sister into helping her against Supergirl. Twilight, Supergirl, and Mary Marvel rescued her in the end, though.
