Harlequin (comics) - Molly Mayne

The original Harlequin was Molly Mayne who appeared in stories alongside the Golden Age Green Lantern (Alan Scott).

Mayne developed a crush on Scott and, donning a colorful costume (which included harlequin glasses, a conical hat, and a mandolin), started a life of crime to attract his attention. Her crimes tended to be harmless and mostly for show, although the two clashed on several occasions in the late 1940s.

She briefly joined the Injustice Society until she turned on them by aiding the Justice Society of America. She had a deep running altruistic streak which occasionally led her to join forces with her enemy/would-be love interest. Despite being attracted to Harlequin, Scott never entered into a relationship with her and she eventually gave up in despair. She made a deal with the government in which she went on intelligence missions in return for amnesty for her past crimes and then quietly retired. On one occasion, she assisted Green Lantern, Superman and Lois Lane in capturing another foe of her love, the Sportsmaster.

Years later, after the death of his first wife Rose Canton, Alan Scott realized that he had loved Molly all this time and they got married. As the years passed a problem developed for the two; the Starheart (which gave Scott his powers) had reversed his aging processes, so he was physically a young man while Molly had since aged into an old woman. In despair over the rift this had caused between them Molly sold her soul to the demon Neron in return for youth in Underworld Unleashed: Abyss - Hell's Sentinel #1. Her body became that of a young woman (who had the power to create nightmares) but her soul remained in the underworld. Scott fought his way through Hell to obtain it and, with the help of the young Green Lantern Kyle Rayner, returned it to the Harlequin's body. This resulted in re-aging Molly, but making her whole once again. Some time thereafter, Scott himself was returned to his true physical age, as well. Mayne and Scott remain happily married to this day.

During the Brightest Day event, Molly briefly appears when Alan's daughter Jenny arrives at the Scott home in search of her father's old lantern. Molly informs her stepdaughter that Alan had been depressed in recent weeks, as Jenny had not been to visit her family since her resurrection at the close of Blackest Night. Later, a doppelganger of the younger, villainous Molly is created by Alan's ring after he goes insane and battles the Justice League. The doppelganger is briefly seen torturing Starman.
