Leader of the Pack.Van Kleiss and the Pack arrive without warning at the Headquarters of the United Nations in New York City, where Rex is forbidden from attacking him due to Van Kleiss possessing diplomatic immunity as the leader of Abysus. Van Kleiss claims he has come to deliver a speech to the United Nations delegates on Abysus's behalf, but Providence remains suspicious of him. Rex is invited to a party by Van Kleiss, which he attends with Six, Bobo, and Holiday. At the party, Rex encounters Circe in an underground passageway, where Breach, one of Van Kleiss's followers, is using her powers to teleport soil from Abysus to New York, thus granting Van Kleiss his full power. Van Kleiss takes the U.N. delegates hostage, but Rex is able to defeat him by blowing a hole in the underground passages and causing them to be flooded by the East River. Rex prepares to kill Van Kleiss, but Van Kleiss reminds him that he knows the identities of his parents, causing Rex to hesitate long enough for him to escape.
