By transforming into electricity, Fritz managed to secretly observe all four Charmed Ones for months as they battled Gaxageal. After the sisters defeated the Old One, Fritz reported back to his partner Valen, who concluded that the Halliwells are unique due to their ability to evade death. Valen then informed Fritz about an artifact known as the Ancient Athame, capable of killing souls and thus wiping them out of existence. Fritz noted he thought it was just a legend, though Valen replied that he knows its location.
