David Xanatos

David Xanatos started life as the son of Petros Xanatos, a Greek immigrant who worked a fisherman from Bar Harbor, Maine. Young Xanatos received an anonymous letter that contained a set of valuable 10th-century coins. He sold the coins for $20,000 and invested the money in a series of successful ventures, thus pulling himself out of poverty in the process. He would later embark on a business career, the first steps toward building his own company, Xanatos Enterprises. Despite his father's belief that Xanatos did not deserve the gift that had launched his career, Xanatos continued to claim that he would one day prove himself a self-made man.

During this time, Xanatos took on Owen Burnett under his wing, a former employee of business rival Halcyon Renard, as his assistant. Eventually, Burnett revealed that he is actually Puck, a Child of Oberon, and offered Xanatos a tempting choice: a single wish (which could grant the immortality he sought) or a lifetime of service as the mortal Owen Burnett. Against Puck's expectations, Xanatos, confident that he could achieve immortality through other methods, chose Owen's service, and the decision deeply impressed Puck to keep his end of the bargain, with the inference that, should Xanatos achieve his goal, he will be guaranteed Puck/Owen's services for eternity.

Xanatos learned of Castle Wyvern from Demona, the only gargoyle from the Wyvern Clan who had neither been destroyed nor put into stone sleep. He purchased the ruins, transported them to Manhattan, and had the structure rebuilt atop his New York skyscraper, the Eyrie Building.[3] With the castle "above the clouds," Xanatos successfully released the Manhattan Clan from their frozen sleep.[3]

Xanatos initially posed as the Gargoyles' friend, convincing them to "acquire" technology from his rival Cyberbiotics for him and ultimately attempting to destroy the gargoyles once their replacements, the Steel Clan, came online. The Steel Clan was defeated, however, and Xanatos was convicted for receiving stolen property ("Awakening, Part V"). Xanatos continued to plot against the Gargoyles from prison, testing them and attempting to remove them from the castle. Upon his release, he became one of their greatest enemies, engaging in a particularly fierce rivalry with their leader, Goliath.

Xanatos also committed himself to getting his own clan of gargoyles that would be loyal and obedient to him. To that end, he tried several attempts throughout the series to do that such as resurrecting Goliath's brother Coldstone and some of the other dead gargoyles from the Wyvern Clan; enlisting the services of a "freelance geneticist" named Dr. Anton Sevarius to craft unwitting human subjects towards genetically creating his own clan of gargoyle-like mutates from humans, one of whom was Elisa Maza's younger brother, Derek; creating a clone of Goliath, and perfecting the Steel Clan. During this time, he also discovered the existence of the Illuminati and became a member.

When his attempts to create his own gargoyle clan failed, Xanatos instead changed his goal to acquiring immortality through the use of sorcery and magic, even involving himself with children of Oberon, including Oberon himself—the formidable Lord of the mystical island of Avalon.

Xanatos would meet an equal in Fox and marry her. It was on this occasion that, by inviting Goliath to the wedding and luring him into seeking reconciliation with Demona, Xanatos was able to reconstruct the Phoenix Gate. The wedding party was brought back in time to the 10th century, where Xanatos arranged for the ancient coins to be delivered to himself a thousand years in the future, via Illuminati, as well as a message to himself describing what to do with them. In this way, Xanatos fulfilled his own history through a predestination paradox, at the same time proving himself to his father as a "self-made man" ("Vows").

When Demona finally betrayed Xanatos to advance her own goals of destroying the human race, he was forced to call a truce with Goliath to stop her.[4][5] Goliath was later instrumental in saving Xanatos's newborn son Alexander, something which Xanatos owed him a great debt, and pledged to pay back to him ("The Gathering, Part II"). He soon created new robotic bodies for Coldstone's other personalities to inhabit, which he named Coldfire and Coldsteel. Since these gargoyles were also created by magic, though, it was impossible for mind transfer to occur. While he and Fox were out to dinner, Puck and Alexander performed the transfer for him. When the existence of the gargoyles was revealed to the public, Xanatos puts an end to the feud between them and voluntarily allows the gargoyles to come back to live in their ancestral castle ("Hunter's Moon, Part III").

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 their future plans towards 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, and "love each other" as much as two people such as themselves can.

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.

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, but silently admits.

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.
