History
The history of this incarnation of Kitty Pryde most likely mirrors that of her Earth-616 counterpart.
Pryde was among the many New York superheroes that responded to a rampage seemingly caused by the Hulk (in reality, it was caused by the Abomination, who had been defeated by Hulk and Power Pack shortly before the heroes arrival). Wanting to be left alone, Hulk angrily attacked the heroes, forcing them to fight him. Like all the others, Pryde found herself outmatched by the green giant until Katie Power used her powers to revert Hulk back to Bruce Banner.
Sometime after this, Wolverine invited Power Pack to visit Xavier's Institute. When Jack Power met Kitty, he instantly fell in love with her and even attended a class lectured by her because of this. Pryde did not return the feelings however. When a group o Sentinels attacked the school, Pryde was among the mutants that tried to fight them off. In the battle, Jack learned to his dismay that she was already in a relationship with Colossus.
