Quinn is not the first DC Comics supervillain to sport the Harlequin name. Her predecessors include the original Harlequin, a foe of the Golden Age Green Lantern Alan Scott, who later became his wife. The second Harlequin originally debuted as the Joker's Daughter, and was a member of the Teen Titans. The third Harlequin was a member of the Injustice Unlimited super-villain team, and battled Infinity, Inc.. The fourth Harlequin has only appeared on a few occasions, and is an enemy of Alan Scott.
