During a fight with the Eradicator (who was attempting to 'hijack' the B13 virus and use it for its own ends), Superman discovered that Brainiac 13 could not cope with Kryptonian technology, due to incompatibility issues. This gave Superman a plan to stop Brainiac 13's scheme. With the aid of the rebuilt Kelex, Superman tricked Luthor into connecting a Kryptonian battlesuit to one of Brainiac 13's power conduits. Kelex then reactivated the Red Tornado to help Superman break Brainiac 13 down into his respective nanobots and trap him in the suit.
