Deliberate mistake: When the news program is discussing Gyrich's assassination attempt on Xavier from the series finale of the original animated series, he's shown to have his classic look of auburn hair and sunglasses. However, when this scene occurred, Gyrich had black hair and was not wearing sunglasses. This was done deliberately to match the character design of the original series prior to the final 6 episodes, when Saban took over and redesigned much of the show's look.

Bright Eyes - S1-E7
Other mistake: SPOILER: Gambit's funeral is taking place in his hometown of New Orleans, as evidenced by the coffins being above ground (because New Orleans is at or below sea level). However, Gambit's coffin is oddly lowered into the ground.
Continuity mistake: When Carl Denti grabs Roberto's face, his thumb is near the corner of Roberto's lips. When the shot changes, his thumb is now on Roberto's cheek.

Trivia: When Cable scoffs at the uniform Cyclops gives him to wear, Cyclops asks if he was expecting black leather. This is a reference to the first X-Men film, when Wolverine scoffed at the X-Men's black leather uniforms, only for Cyclops to ask him if he preferred yellow spandex instead.
Trivia: Some episode intros feature a shot of Gambit cradling Rogue on the basketball court, and she proceeds to cover his mouth with her hand and then kiss her hand. This is recreated from a panel in X-Men #4, though in that panel, Rogue punched Gambit in the mouth instead of giving him a simulated kiss.

Magneto: Yet so many allow their leaders to be terrorists.

Madelyne Pryor: [In labor pains] Logan, he's, he's here!
Wolverine: Who? Apocalypse?
Madelyne Pryor: The baby!
Wolverine: Oh, crap!
Question: Why did writers decide to kill Gambit off?





Answer: The post-credits scene from season 1 implies that Apocalypse is going to bring him back to life as his Horseman of Death, which Gambit was at one point in the comics. I also read that former showrunner Beau DeMayo had planned for Gambit to be the central character of season 3, which would have been an adaptation of the Age of Apocalypse storyline from the comics, which seems to imply Gambit will eventually be freed from Apocalypse's control. Whether that is what ends up happening remains to be seen, since DeMayo was fired by Marvel before season 1 premiered.
