Though he does love Fox, he is shown using her to get what he wants as well. In the Halloween episode, Xanatos gives Fox the Avalon-crafted Eye of Odin as an engagement gift. The necklace holds unfathomable occult powers that Fox cannot control. It turns her into a large red-haired beast, looking like a 'fox'-human hybrid bearing a resemblance to a werewolf. Though Xanatos suspects it has an effect on her, he does not fully understand, until he witnesses Fox transform in front of him. Terrified by what he has set into motion, he asks Goliath and Elisa for assistance, though they are initially reluctant. Goliath seems especially perturbed at how he has treated Fox and seemingly disregarded her life.
