When Lyle betrayed Cosmic Boy's trust by revealing to Brainiac 5 that several members had broken into Brainy's lab, he lied to the team by blaming everything on Shrinking Violet. He and Violet, who prefers the moniker Atom Girl, have since made a deal to continue the ruse, but his teammates still have a hard time trusting him. When Supergirl mysteriously appeared in the 31st Century, Lyle, along with half the male Legionnaires vied for her attention. However, Lyle convinced Cosmic Boy that he did not have a crush on Supergirl in order to remove the competition for her affections. He recently had his arm torn off when his flight ring exploded, and was given an alien arm to replace it by a member of the Wanderers. He is left in Metropolis, the doctors reproducing his DNA to give him another arm.
