Shadowcat's X-Treme X-Men Costume
Katherine Anne "Kitty" Pryde was born in Deerfield, Illinois to Carmen and Theresa Pryde. Of Jewish descent, her paternal grandfather, Samuel Prydeman, was held in a Nazi concentration camp during World War II. Kitty started to have headaches at age fifteen, headaches which signaled the emergence of her mutant powers. She was approached by both the X-Men's Charles Xavier and the Hellfire Club's White Queen, Emma Frost, both of whom hoped to recruit her for their respective causes. Kitty was unnerved by Frost, observing that the White Queen had looked at her as if she were "something good to eat." She got along better with Xavier and the three X-Men who escorted him to his meeting with her and her parents, becoming fast friends with Ororo Munroe. Ororo told Kitty who she really was and about the X-Men, which made the teenager even more enthusiastic about attending Xavier's school.
Their conversation was cut short, however, when they (along with Wolverine and Colossus) were attacked by armored mercenaries in the employ of Frost and the Hellfire Club. The X-Men defeated their assailants, but were subdued by the White Queen's telepathic powers immediately after. In the confusion, Kitty had become separated from the X-Men and therefore was not captured along with them. She managed to contact Cyclops, Phoenix, and Nightcrawler. With the help of Dazzler and Pryde, those X-Men rescued their teammates and Xavier (who had also been captured) from the Hellfire Club.
The White Queen appeared to perish in the battle, which meant she was no longer competing with Xavier for the approval of Kitty's parents. Unfortunately, Kitty's parents hadn't heard from her in more than a day, because during that time she was first being pursued by the Hellfire Club's men and then working with the X-Men to save their friends. All they knew was that Kitty had left with Xavier's "students" to get a soda, there had been reports that the soda shop had been blown up, and that Kitty had been missing since. Understandably, they were angry at Xavier when he finally returned with Kitty in tow. At first, it seemed like there was no chance of Kitty being allowed to attend the school and join the X-Men. Phoenix then decided to use her considerable telepathic power to erase the memories of Kitty's parents and plant false ones, resulting in a complete shift in their attitude towards Xavier. Questions concerning the morality of tampering with minds in such a fashion aside, Kitty was then allowed to enroll at Xavier's school with her parents' blessing. She was the youngest person to join the X-Men up to that point.
Kitty joined the X-Men, and assumed the costumed identity of Sprite. Early in her career as an X-Man, Kitty's adult self from an alternate future took possession of her body in the present to help X-Men thwart the assassination of Senator Robert Kelly by the second Brotherhood of Evil Mutants. Kitty then singlehandedly defeated a N'Garai demon. Kitty also briefly attended the White Queen's Massachusetts Academy.
During her teen years, Kitty fostered a number of close relationships with others at the school and in the X-Men. She developed a crush on Colossus and became close friends with his little sister Illyana Rasputin. Initially uneasy around Nightcrawler and other mutants with physical deformities, Kitty finally overcame her fears and became close friends with him. Kitty also befriended Lockheed, a highly intelligent alien resembling a dragon, who followed her home after a mission in outer space. Lockheed is extremely loyal to Kitty, and the two of them share a psychic bond. Wolverine became something of a mentor to Kitty despite his usually gruff personality. Storm came to view Kitty as the daughter she never had.
Kitty was later assigned to the New Mutants, a team of younger mutants established in the absence of the X-Men while they were in outer space. Kitty convinced Professor Xavier to allow her to remain a full member of the X-Men on the basis of her high intelligence, maturity, and the fact that she was already a fully-trained member of the team. Kitty was later abducted by the Morlocks and nearly forced to wed Caliban. She was then abducted by the White Queen, but rescued by the New Mutants.
During this time, Kitty began to "date" Colossus, but this did not last long. Colossus developed feelings for an alien woman named Zsaji whom he met on the Beyonder's planet in the first Secret Wars. Colossus' feelings toward Zsaji were primarily a side effect of her own unique healing abilities, which she had used on him after he became injured. Regardless, Colossus' feelings were real and he returned to Earth consumed with grief after Zsaji's death. He admitted to Kitty that he loved Zsaji, which hurt her deeply and ended the budding romantic relationship. Kitty had made good friends with a local boy from Salem Central named Doug Ramsey around this time, but her feelings for him never went as deep as his for her, and they never actually dated, though they remained close, even more so after Doug's status as a mutant was revealed and he joined the New Mutants under the codename Cypher. They remained friends until his death some time later.
During the 1985 Kitty Pryde and Wolverine miniseries, Kitty is possessed by a demon, the ninja Ogun. Ogun psychically bestows upon Kitty a virtual lifetime of martial arts training. Kitty was brainwashed by Ogun into becoming a ninja assassin, and was sent to attack Wolverine. Kitty is able to resist Ogun's influence with Wolverine's help and the two form a strong teacher/student bond. Kitty returns to the X-Men, no longer the innocent girl they once knew, and officially adopts the codename Shadowcat.
Kitty was badly injured by Harpoon's energy spear during the Mutant Massacre story arc, in the massacre of the Morlocks, with the result that she lost control of her power and was stuck in an intangible state and could not regain her solidity. She was rushed to Muir Island along with other surviving casualties of the Massacre to be tended to by Moira MacTaggert. MacTaggert was able to keep Kitty's condition from deteriorating to the point where she completely lost physical substance and ceased to exist, but wasn't able to do any more to help her. At this time, Kitty's natural state was to be intangible. Where she once had to make a conscious effort to phase, she could now only maintain her solidity through an act of conscious will. She was saved by Reed Richards, Mister Fantastic of the Fantastic Four, but not without trouble. The X-Men had gone to Richards for aid, but he had initially refused because he was not sure he would be able to help (Reed was in a struggle with the rest of the Fantastic Four about their origins. They thought that Reed deliberately caused their accident which turned them into the Fantastic Four, thus making him very uncertain about his personal motives and abilities). Having nowhere else to go, the X-Men turned to Richards' enemy Doctor Doom. This created a moral dilemma for both the X-Men and the Fantastic Four. Both teams fought each other because the Fantastic Four were trying to stop the treatment while the X-Men were determined to save Kitty's life. In the end, both the personal crisis of the Fantastic Four and the life of Shadowcat were saved. It was Franklin Richards, with the help of Lockheed, who brought both teams to their senses. Kitty has since recovered from this state and now has full control over her power again.
