Madelyne Pryor
Madelyne Pryor was introduced during the acclaimed 1983 "Uncanny X-Men" run that saw long-time writer Chris Claremont pair with artist Paul Smith for a series of issues that would see the Jean Grey look-alike marry the retired X-Men leader Scott Summers (Cyclops).
Kitty Pryde
The fictional Kitty Pryde first appeared in "Uncanny X-Men" #129 (January 1980), by writer Chris Claremont and artist Byrne, as a highly intelligent 13-year-old girl. Claremont said several elements of the character's personality were derived from those of "X-Men" editor Louise Simonson's daughter, Julie. Claremont and Byrne made the new character a full-fledged X-Man in issue #139, where she was codenamed "Sprite". She was the main character in issues #141–142, the "Days of Future Past" storyline, where she is possessed by her older self, whose consciousness time travels to the past to prevent a mass extermination of mutants. The six-issue miniseries "Kitty Pryde and Wolverine" (1984–1985), written by Claremont, is a coming-of-age storyline in which she matures from a girl to a young woman, adopting the new name "Shadowcat".
