Kitty Pryde is a Jewish mutant with versatile phasing abilities which allow her to move through solid matter. After her powers first manifested, Pryde was approached both by Emma Frost, the White Queen of the Hellfire Club, and the X-Men, a mutant superhero group. Realizing Frost had vile intentions as she captured and tortured the X-Men, Pryde demonstrated immense bravery and freed the X-Men. As Sprite, she became the X-Men's youngest member by enrolling at Xavier's School for Gifted Youngsters.
Proving to be a controversial but invigorating addition to the team, Pryde had her life completely guided by her tenure with the X-Men, who became her second family. After being brainwashed by the sword master known as Ogun, Pryde connected herself with darker aspects of her soul, adopting the codename Shadowcat for years. She was also a founding member of the British-based mutant team known as Excalibur, experiencing an exceptional adolescence, by growing up as a superhero. As an adult, she returned to the X-Men and, as a mutant superhero, she had a great impact on the world, such as sacrificing her freedom to save Earth, becoming the headmistress of the Xavier's School, and leading the X-Men.
More recently, Pryde had a drastic change of attitude. After mutantkind moved to the island nation of Krakoa, Pryde was seemingly unable to interact with the island's functionalities. As this exclusion put her own identity into question, she started calling herself "Kate" and adopted a more ruthless position, forming the Marauders, a group of mutant raiders who rescue mutants from non-amicable nations. Moreover, she found herself in coalition with Emma Frost, by becoming the Red Queen of the Krakoan Hellfire Trading Company and joining the Quiet Council of Krakoa, the Krakoan governing body.
