Shadowcat is a mutant and part of the X-Men. She was one of the original students recruited to the team. After the New Mutants were formed, Kitty served as an instructor for them, alongside the other original students. She formed a relationship with Avalanche, who she broke up and rekindled with on numerous occasions. She developed deep friendships with Jean Grey, Rogue, Nightcrawler and Cyclops, the latter she initially expressed romantic interest in. She also had a father-daughter relationship with Wolverine, who she saved and had been saved by on occasion.
She served as the leader of the X-Men sent to fight against Magneto while he was controlled by Apocalypse, operating against his will as a member of the Horsemen of Apocalypse. During the battle, she was knocked out by Magneto with the use of his controlled-Sentinel and rescued by the Brotherhood of Mutants, a group of mutants that Kitty had been enemies with ever since joining the X-Men. She reaffirmed her relationship with Avalanche for the final time after Apocalypse was defeated and in a vision Charles Xavier had of his X-Men in the future, she was still a member of the team as an adult.
Little is known about Kitty before she discovered her mutant powers. She was a good child who got along well with her parents. However, at school she was considered nerdy and picked on by other girls. The most prominent of these girls was Riley, who had become aware that Kitty was getting high grades and often tried to make fun of it with a friend of hers. She began to pick on Kitty at school sometime after this discovery and was not seen by any of the teachers.
Joining the X-Men
The young lady developed her powers over the course of a dream, where she was flying and without control.
Powers and Abilities
Kitty has the ability to phase through solid matter, this lets her walk through walls and walk on air. She can also phase various objects with her, though the larger the object the greater the strain it puts on her.
Kitty was initially vibrant in her wishes to remain a normal human, rather than the mutant she was becoming. Though her powers posed no real threat to her living a normal life, her initial reluctance to use them secretly caused a detractor, Lance Alvers, to become aware of them and try to use them for his own purposes. Kitty was very intelligent, and easily saw through his tricks once she used her powers to get the two into their school's office and he started to change grades. Despite not initially understanding, her knowing of right from wrong was on track. She knew that what he was doing was not something to take comfort in, nor be a part of.
Shadowcat was voiced by Maggie Blue O'Hara.
First time Kitty appeared in animation since she appeared in the proposed "Pryde of the X-Men" pilot, named after her. In it, Kitty was the newest member of the X-Men. However, her characterization was highly criticized as being annoying and whiny. When X-Men was produced, Jubilee essentially filled the same role with the same criticisms. This was largely why Kitty was absent from the series.
