Silver Banshee

Silver Banshee is a super-villain with sonic powers and an enemy to Superman. Her family occupies Castle Broen on an island between Ireland and Scotland, where her father was the patriarch of their clan. During a conflict for leadership through supernatural forces, Siobhan McDougal was dragged into the netherworld and granted powers by a creature called the Crone. This turned her into a Banshee with the ability to use hypersonic screams, allowing her to violently deal with her enemies. She has been a member of the Secret Society of Super-Villains. In the New 52 reboot, she was renamed as Siobhan Smythe.
