High Quality Content by WIKIPEDIA articles! Night of the Sentinels is a two-part pilot episode of the 1990s X-Men animated series. It originally aired on October 31 and November 7, 1992. The episode is loosely based upon "Uncanny X-Men #14". Introduced in the episode were an X-Men team similar in look and line-up to the early 1990s X-Men drawn by Jim Lee. The members of the X-Men introduced compose of Professor X, Cyclops, Beast, Jean Grey, Wolverine, Rogue, Gambit, Storm and Jubilee, as well as an original character, Morph. The series was originally to premiere over the Labor Day weekend in September; however, due to production delays, it was pushed to the end of October. The two-parter aired as a "sneak preview" even though it was not considered ready for broadcast. Therefore, there were many animation errors. However, the errors were later corrected when FOX re-aired the pilot in early 1993.
