X-Men The first X-Men animated series debuted on October 31, 1992 on the Fox Network as part of the "Fox Kids" Saturday morning lineup. The plot was loosely adapted from famous storylines and events in the X-Men comics, such as the Dark Phoenix Saga, Days of Future Past, the Phalanx Covenant, and the Legacy Virus. The show features a team line-up similar to that of the early 1990s X-Men comic books: the lineup largely resembles that of Cyclops' Blue Team, established in the early issues of the second X-Men comic series.
