List of X-Men episodes

The 1992 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 line-up largely resembles that of Cyclops' Blue Team, established in the early issues of the second X-Men comic series.

The series' first 13 episodes were notable for being possibly the first time ever that an American animated series had a full season of episodes flow one into the next, creating a single continuing narrative, something the series producers fought heavily for. However, starting with season three, most episodes (except for multi-part stories) were shown in random order.

Each episode was assigned two different numbers internally. One is for Script Order, which indicates the number assigned by the production company. The other is for Production Order, which are the official episode numbers assigned by FOX Children's Network, indicating the order in which they received the episodes. These both vary from the order in which the series actually aired after season three. According to series writer Steven Melching, the Script Order is the "best guide in terms of overall series continuity, as this is how the stories were originally envisioned to flow together."

The X-Men also appeared on Spider-Man in episodes "The Mutant Agenda" and "Mutants' Revenge". Storm later appeared in the three part episode "Secret Wars".

As of 2009, the X-Men animated show stands as the longest-running Marvel Comics based TV show, lasting for six years, with five seasons and a total of 76 episodes. The series was canceled after the episode "Graduation Day", which aired on September 20, 1997.

Season one
The continuity within the first season of X-Men, according to Story Editor Eric Lewald: "The first season order was thirteen episodes, which was standard for a network show. The Sentinel story wrapped up at the end of the season because the writers were not sure that there would be more than one season. Looking back at the previous Marvel animated adaptations, there was great fear that X-Men would fail. When the first season became a number one hit, the network ordered 39 more episodes."

Season three
After the "Phoenix Saga," episodes were aired in a more random sequence. Also, due to animation problems with a few episodes, several would not appear until the fourth or even fifth season.

Season four
Some of the Season 4 episodes were aired during Season 3 to compensate for episodes in that season being pushed back.

Season five
"Beyond Good and Evil" was meant to be an ending to the series, until FOX bought a few more episodes at the last minute. As such, the final six episodes have a different animation style. Saban hired a studio in the Philippines (simply called the Philippine Animation Studio, which also worked on the second season of the 1994 Fantastic Four series) because the animation studio AKOM (the company that did the previous four seasons) was un-available due to other projects in their pipeline. Production costs could have also been another reason why they changed studios.
