Dr. Larsen was a former student of Niles Caulder, but they had a falling out after Larsen accused Caulder of stealing his idea for the anti-decay ray. Larsen gained his superpowers after falling into a vat of amino acids. He used his powers to get revenge on Caulder and Doom Patrol. The Doom Patrol defeated him and were able to remove his powers. He later regained them (in Doom Patrol Vol. 1, #95, May 1965) and fought the Doom Patrol again
