Uncanny X-Men, Vol. 1 #157 (1982)

Hide-'n'-Seek!
Professor Xavier's plan goes into action, thanks to Kitty and Nightcrawler. They are able to delay the Shi'Ar Samedar long enough for Lilandra's health and safety to be established, but not quickly enough to save every member of the team from possibly irreparable harm.
