Through time travel, Sloane and his successor, Michael Holt, have met. Sloane, Holt's JSA, and the Freedom Fighters of Sloane's time teamed up to stop a rampaging, highly destructive time traveler. In the past, the villain had already damaged many parts of Washington D.C., killing many, but they were able to defeat him when Sloane tricked the time traveller into thinking that he was the time traveller's ancestor, threatening to shoot himself before he could have any children to cut the other man's family history short (Although he later admitted that he was bluffing as it would be impossible to determine a family connection given the numerous generations between Sloane and the time traveller). Despite the JSA trying to be secretive, Sloane figured out much about their mission and methods.
