Relationships
Though at first Xanatos seems to have an on and off partnership with Demona when neither magic nor technology seem to be enough to accomplish what they plan to do, neither Xanatos nor Demona seem to truly trust one another. This proves to be a fatal flaw on their part that tends to doom plans to failure.
In general, Xanatos has an odd way of dealing with those he "loves". One example can be found in Thailog, Goliath's clone that he had Sevarius create. While the clone was being grown he had a program playing giving him information about the world and his beliefs. He seemed to have a paternal feeling towards Thailog as, when the gargoyle was kidnapped during his stone slumber, he would not let Owen fire on the kidnappers out of fear of hurting Thailog, and handed over $20,000,000 for his safe return without a second thought. He even showed pride in Thailog's manipulative abilities and genius when he found out the clone had engineered the entire plot to abscond with the money, referring to him as "a chip off the ole block". He even expressed to Thailog that if he wanted the money he would have given it to him if he would have asked for it. However his paternalism seems thin as, when he thinks Thailog died during battle with Goliath, he states that he knew the whole time that a copy (Thailog) couldn't match the original (Goliath), which infuriates Goliath as Xanatos was able to dehumanize a living being to such terms. Though arguably lacking romance, Xanatos asks Fox to marry him on the basis that "it makes sense" because they are genetically compatible, share the same interests, think the same way, enjoy the finer things in life, and "love each other" as much as two people such as themselves can. Fox accepts, yet Xanatos's feelings for Fox are largely debatable.
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 Eye of Odin as an engagement gift. The necklace holds unfathomable power 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.
As Fox continues to go on rampages in search for food, Xanatos, Goliath, and Elisa scour the city for her. Eventually, they chase her to a rooftop and Goliath is able to free Fox from the Eye of Odin after electrocuting her with a neon sign. While preparing to leave and while holding Fox in his arms, Xanatos regretfully informs Goliath that now he knows his only weakness. Goliath turns to him, slightly disgusted and remarks, "Only you would regard love as a weakness." These words leave Xanatos speechless.
In the episodes of the Gathering, Xanatos seems instinctively protective of both Fox and Alexander, seemingly having come to terms with the idea of love not being a weakness.
