The Female Furies arrived on Hawaii to reclaim Knockout. A battle broke out between Superboy, Knockout, and a small contingent of police officers against the Furies. One police officer died during the battle, but the Furies were driven off when Dubbilex used his mental abilities to convince them that Knockout had died in the battle as well. Dubbilex investigated the murder of the police officer, using his mental powers to scan the memories of most of the survivors. They soon realized that Knockout had killed the officer simply because he was in her way.
