The Not-Aris are an army of Erasers created by Jeb with the help of Dr. Hans Gunther-Hagen. They are Ari clones led by a new, improved Ari, and they are all linked to him; because of this, when he died from the fight with Dylan in Nevermore, they all died too. However, unlike Ari, they were useful as warriors; they were meant for one mission, and one mission only: to eliminate Fang before his immortal DNA destroyed the planet in the scientific world.
