Kitty's mother, worried about Kitty's mutation, seeks help from Professor Charles Xavier. Kitty becomes a student at Xavier's school, when her mother allows her to attend under the condition she does not take part in any X-Men missions, nor train in any "Danger Room" simulations. Kitty soon rebels against this and joins the X-Men as their youngest member. She idolizes Spider-Man and has a crush on him; she even dates Peter Parker for a time. After a fierce argument with Professor Xavier concerning Peter's secret identity, which his Aunt May had just found out about, Kitty leaves the X-Men and enrolls in Peter's school. Their relationship is strained after their romantic involvement (as superheroes) becomes publicly known, making it impossible for them to date anymore in their civilian identities, and eventually comes to an end when Peter realizes he cannot get over his feelings for Mary Jane. However, Kitty still retains strong feelings for him.
Following the disastrous flood triggered by Magneto and the subsequent ban of public use of mutant powers, Kitty assumes the identity of the Shroud. When the authorities find out that she has continued to use her powers, however, she becomes angry even towards her close friends and flees into the sewers, thereby demonstrating her new ability to alter her mass to become extremely dense, becoming capable of even punching Spider-Man several feet through the air in a rage. Kitty also located Jimmy Hudson, who is revealed to be Wolverine's son. Kitty was charged by Logan before his death to locate Jimmy and reveal his true origins to him.
