Bright Eyes - S1-E7
Trivia: Trask refers to Mr. Sinister's Sentinel attack on Genosha as a "mutant massacre." In the comics, there is a storyline called "Mutant Massacre," which saw Sinister tasking a group of mutants called the Marauders to kill the Morlocks. Years later, it was revealed that Gambit was hired to help sneak the Marauders into the Morlock tunnels, making him culpable in the act. This is contrary to Gambit helping to save some Morlocks from the Sentinel attack in this show.

Trivia: Ross Marquand, who voices Professor X, previously portrayed Red Skull in Avengers: Infinity War and Avengers: Endgame. Cedric Smith, who voiced Professor X in the original animated series, also voiced Red Skull in one of the series' final episodes.
Trivia: Several actors from the original series are returning to voice different characters. Chris Potter, who voiced Gambit, will now be voicing Cable, while original Cable actor, Lawrence Bayne, will be voicing X-Cutioner. Catherine Disher, who voiced Jean Grey, will be voicing Valerie Cooper. Ron Rubin, who voiced Morph, will be voicing President Kelly. Alyson Court, who voiced Jubilee, will be voicing Abcissa, who is an older and digital replica of Jubilee.
Trivia: Jennifer Hale is taking over the role of Jean Grey from Catherine Disher. Hale previously voiced Jean Grey in Wolverine and the X-Men. She also previously voiced Felicia Hardy/Black Cat and Julia Carpenter/Spider Woman in the 90's Spider-Man and Iron Man animated series, respectively, which take place in the same continuity as this show.
Trivia: Ahead of its premiere, it was announced that Morph, who was created for the original animated series, would be non-binary. This led to backlash from some fans, claiming that the show was going "woke." Eric and Julia Lewald, who created the original series, pushed back against these fans, asking if they had learned nothing from the show and the comics that inspired it, as it was always an allegory for civil rights and highlighted people who were different from the norm and dealt with bigotry.
