Madelyne Jennifer "Maddie" Pryor is a character appearing in American comic books published by Marvel Comics. Created by writer Chris Claremont and artist Paul Smith, the character first appeared in Uncanny X-Men #168 (April 1983). Primarily featured off-and-on as an antagonist of the X-Men, Madelyne Pryor is the ex-love-interest and first wife of Cyclops, a clone of Jean Grey, and the mother of Cable. She was a long-standing member of the X-Men supporting cast until a series of traumas eventually led to her being manipulated into being a supervillain known as the Goblin Queen.
According to Claremont, the original link between Madelyne and Jean was entirely the product of Mastermind. Seeking revenge against the X-Men after Mastermind was driven insane, Mastermind's powers of illusion to convince the X-Men that Madelyne is the Phoenix—a cosmic threat—in an attempt to have the team kill her. Mastermind's plan fails, and Madelyne and Cyclops are married shortly after. Claremont had conceived Madelyne as a device to write Cyclops out of the X-Men and have retire "happily ever after" with Madelyne and their child. The story became more complicated in 1986 when moves by the editors and other writers to reunite the original X-Men, for the new title X-Factor, resulted in Jean's resurrection and Scott leaving his wife and son. This deeply compromised Cyclops's character and left little room for Madelyne, and Cyclops's actions then—and towards even Jean much later—have been controversial ever since. Marvel avoided addressing these problems, instead resorting to a deus ex machina, in the 1989 Inferno crossover (co-scripted by Simonson with Claremont), in which Madelyne is retconned to be a clone of Jean created by Mister Sinister to produce a child with Cyclops, and corrupted by her anger and demonic influence as the Goblin Queen, leading to her elimination and into an object of damnatio memoriae (and "nonperson" status) for several years.
