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.
