History
Shadowcat was among her fellow X-Men teammates who were playing a game of baseball when the Press Gang from Genosha attacked them in order to kidnap their healer Triage.[1]
Kitty got involved in the battle with Lockheed by her side but she used her phasing abilities to help push Anole out of the way of Havok's plasma blast. The burst disrupted her powers knocking her onto the ground.
Nightcrawler teleported her to Memorial Hospital to be diagnosed by Dr. Reyes who at some point got knocked out and replaced by the shapeshifter Mystique. Kitty only suffered from a concussion.[2]
