Avril Fenman

, also known as "the Soul Sucker", was squire to knight Cherry of the Female Knights of Rowan, until one day she abandoned her knight when she took a crystal that gave her the power to transfer her mind into the bodies of others. She later used this power to take over Bernice Summerfield's body and sleep with Adrian Wall, impregnating Benny with human-Killoran hybrid that would become Peter Summerfield. (PROSE: The Squire's Crystal) Many years later, she came back to claim Peter as her son before getting killed by Peter. (AUDIO: The Curse of Fenman)
