Along with fellow founding Legion members Rokk Krinn and Garth Ranzz, Garth traveled through time back to the 21st century to stop the Persuader from killing Clark Kent. They found him to be at Clark's barn where he had just returned from seeing Jimmy Olsen off to Star City. After he had cut open his abdomen, Rokk took away his Atomic Axe using his ability of magnetism control and Imra distracted him using telepathy enough so that Garth could knock him out using his electricity before Rokk took away his stolen Legion ring sending him back to the 31st century.
Rokk, Garth and Imra then introduced themselves to Clark as the Legion of Super-Heroes. The three explained to Clark what he is truly destined to be, which is a model for all of the galaxy for aliens to come to Earth and live among humans. The three Legion members decided to help Clark defeat Brainiac, even if it had to kill its human host: Chloe Sullivan, although he refused their help. Imra went to see Lana Lang, to have her convince Clark to sacrifice Chloe to destroy Brainiac. The Legion attacked Brainiac, managing to subdue it while they tried to find a way to kill it. Working together with Clark, finally, Imra helped Clark connect with Chloe from within and held her down as Garth and Rokk used their powers to extract the particles of Brainiac.
As Lana was tempted to ask of her future, Imra only told her that she has a destiny to fulfill as well and that "her secret" would be safe with her. Imra, Rokk, and Garth had later returned to the future with what was left of Brainiac saying that they would reprogram it to be more productive, naming it 'Brainiac 5'. Imra voiced her hope that the new Brainiac would be "a little more friendly".
