The Phoenix Saga (2): The Dark Shroud - S3-E4
Trivia: Beast can be seen wearing a Howard the Duck T-shirt in this episode.
Trivia: Lady Deathstrike's outfit had to be slightly modified due to censorship issues. In the show she is wearing a white shirt under her vest. In the comics, the white shirt is not there, revealing a lot of cleavage. Obviously not acceptable for a kids' Saturday morning cartoon show. Director Larry Houston even stated that they deliberately drew her flat-chested in storyboards, because they knew her large breasts would be an issue. However, Philippine Animation Studio, Inc, who were hired to animate the episode, were supposedly huge fans of Marvel Comics and took it upon themselves to improve on the storyboards they were given, and animated her in such a way, that when she would turn, her breasts would follow through and settle. Houston claims he still has the raw VHS footage of this animation in storage.
Mojovision - S2-E11
Trivia: One of the women tending to Longshot in his dressing room when Mojo is firing him is Dazzler, who would make her first official appearance on the show in the season 3 episode "The Dark Phoenix Saga Part 1, Dazzled" although with a different hair color. Longshot and Dazzler were a romantic item in the comics.
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
