Kirt Niedrigh first appeared trying out for membership in the Legion of Super-Heroes. Calling himself Absorbancy Boy, and possessing the ability to absorb the energy residue of any super-powered being, gaining their powers himself. He was rejected on the grounds that his powers were too limited.
Incensed at his rejection, Niedrigh found the costume of 'Zoraz', a fake villain used as a final test for new Legionnaires. Attacking the Legion and defeating them, Niedrigh revealed himself, believing that he had earned his place on the team. The Legion did not see things this way, and Superboy attempted to confiscate the suit. Niedrigh used the suit to project red sun radiation and, absorbing Superboy's powers, was able to defeat the Kryptonian. Niedrigh was then defeated by the Legion's new member Tyroc, who used an ultrasonic scream to blister his newly-acquired superhearing.
Years later, after the Dominators had secretly taken over Earth and disbanded the Legion, Kirt's name appeared on a list of Dominator test subjects.
