Fan Casting Silver Banshee in Return to the DC Universe

Centuries ago, Siobhan McDougal was to be the next leader of the McDougal Clan, but was opposed by her brother and uncle. When attempting the ritual to ascend to leadership of the clan, her brother interrupted the ritual, botching it and causing her to be sent to the Netherverse for centuries, where Siobhan met the Crone, an ancestor of hers, leading her to become the Silver Banshee, using her powers first to exact revenge, then to combat heroes such as Superman when she was freed form her imprisonment.
