I loved Evolution Shadowcat. Her and Rogue were my two favorites on the show.
I'm always surprised to realize that Evo was my first long-form exposure to Kitty as a character. She was in Excalibur when I first got into comics, but I somehow either never saw it for sale or just never bought it. So the only things I can recall owning with her beforehand are a single Claremont reprint, the issue of Uncanny where Illyana dies of the Legacy Virus, and Pryde of the X-Men. It was still enough to leave an impression though. :)
