Planet X (Star Trek)

Planet X (ISBN 0671019163) is a 1998 Star Trek novel by Michael Jan Friedman which is a crossover between the X-Men comic book series and the characters of Star Trek: The Next Generation. A New York Times bestseller, it was a sequel to an earlier crossover, detailed in the Marvel Comics one-shot Second Contact (which was itself similar to an earlier Star Trek/X-Men crossover comic, where a slightly different team of X-Men encountered the characters of the original Star Trek series). The novel is noteworthy for hinting at an attraction between Jean-Luc Picard and Ororo Munroe (Storm), and made a forward-looking reference to the (then uncast) X-Men feature film by remarking on the uncanny resemblance between Picard and Xavier, as the two converse via the holodeck after a reasonable facsimile of Xavier is programmed into it; (both characters were played by Patrick Stewart in Star Trek: The Next Generation and the X-Men film series).
