It has been established that Terrific's brother Ned was the grandfather of the Modern Age criminal Roulette; however, in her original appearance, Roulette believed for unknown reasons that Terrific himself was her grandfather and regarded the new Mister Terrific as a pretender to the role. During a separate time-travel adventure, Michael Holt helps Sloane after he has abducted Ned's daughter from the original Roulette's lair, refusing to allow his niece to grow up in a den of gamblers. It can be inferred that Sloane adopted his niece, thus explaining Roulette's assumption that Sloane is her grandfather.
