The Xanatos Program is a minor antagonist in the Kingdom Hearts Unlimited Saga, only appearing in "Return of the Keyblade" as a powerful entity to be fought against for the Avalon-Manhattan campaign.
A digital program replica of David Xanatos developed by the Master Control Program to serve as a replacement for the real deal within the ranks of the Galactic Empire, the Program had its personality components tweaked to a much more colder, ruthless, and grandiose demeanor so as to satisfy Emperor Palpatine's requirements for his associates. He is equipped with high-tech weaponry and an upgraded Crimson Steel Clan armor, and is currently sent to Avalon/New York City to try and conquer the world through the Internet - wireless network. His mental schematics were inspired by those of COYOTE and Ultron.
