A young mutant from Chicago whose phasing abilities attracted the attention of both Prof. X and the White Queen, Kitty joined the X-Men after rescuing the former from the latter. She first took the codenames Ariel and Sprite. (She was not associated with others using these names.) Kitty was the youngest member of the team , but rejected demotion to the ranks of the younger New Mutants.
Later, as Shadowcat, she was seriously injured in battle with the Marauders. While she was recovering in Scotland with Nightcrawler, she got an invitation to join the new Xavier Academy in Ireland and has accepted.
