The Dark Phoenix (4): The Fate of the Phoenix - S3-E14

The Dark Phoenix (2): The Inner Circle - S3-E12
Trivia: When the waiter is on the phone, he asks where his Chateau Calamari 59 is. This is a reference to Joseph Calamari, who has been Executive Vice President at Marvel Comics since 1986 and was also an executive producer on this show. (00:07:15)
The Dark Phoenix (2): The Inner Circle - S3-E12

The Phoenix Saga (4): The Starjammers - S3-E6
Trivia: Marvel Superheroes Captain Britain and Doctor Strange make brief cameo appearances when Phoenix departs the Earth with the X-Men. (00:04:50)
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.
Trivia: The show contained numerous references to the Terminator film series. Several episodes such as "Time Fugitives" and "One Man's Worth" (also "Days of Future Past," but that was based on a pre-Terminator comic) featured one or more characters traveling into the past to prevent an event that causes a dystopian future. The robots from Cable's future bear a resemblance to the T-800s. When Mr. Sinister's body is blown to bits in "Reunion, Part 2" it begins to reassemble itself exactly like the T-1000 when it was frozen and then blown to bits. Wolverine even refers to Bishop as Mr. Terminator in the episode "Days of Future Past, Part 1." Another Schwarzenegger movie, "Total Recall", is referenced in "Time Fugitives, Part 2" when Cable uses a hologram of himself in order to bait someone into shooting at him.
Time Fugitives: Part 1 - S2-E7
Trivia: War Machine (the supporting character from Iron Man) makes two brief cameo appearances in this episode. The first is in Cable's future after Cable tells his team that they aren't retreating. Whether or not the person inside the armor is James Rhodes or why he is a servant of Apocalypse is not explained. The second is when he is watching the Senate committee on TV along with G.W. Bridge and Nick Fury. (00:02:50)
