Harlequin was a riot girl and one of many to follow the Joker's chaotic style. During the middle of a battle with a group of metahumans while endangering civilian bystanders with disregard, Harlequin was subdued by Superman. She was among the many rogue metahumans who were imprisoned at the Gulag by the Justice League and subsequently survived the U.N. nuclear bombing. Harlequin later became a reformed resident at Paradise Island.
