Penny Polendina was a character who first appeared in "The Stray". She was originally an android created by her father, Pietro Polendina, when he somehow gave her a part of his own Aura to grant her a soul. In "PvP", Penny was destroyed by her own weapons during her fight with Pyrrha Nikos. She returned in "The Greatest Kingdom" with a new look made by her father who rebuilt her after the Fall of Beacon. Throughout Volume 7, she served as the official protector of Mantle and eliminated Grimm that invaded the city. In "The Enemy of Trust" after a grueling battle with Cinder Fall, she became the Winter Maiden.
