features several new actors taking on roles from the original series, including Ray Chase as Cyclops, Jennifer Hale as Jean Grey, J. P. Karliak as Morph, and A. J. LoCascio as Gambit
With the revival's announcement, several voice actors were revealed to be returning from the original series: Cal Dodd (James "Logan" Howlett / Wolverine), Lenore Zann (Rogue), George Buza (Henry "Hank" McCoy / Beast), Catherine Disher (Jean Grey), Chris Potter (Remy LeBeau / Gambit), Alison Sealy-Smith (Ororo Munroe / Storm), Adrian Hough (Kurt Wagner / Nightcrawler), Christopher Britton (Nathaniel Essex / Mister Sinister), and Alyson Court (Jubilation Lee / Jubilee). Lawrence Bayne (Nathan Summers / Cable) and Ron Rubin (Morph) also returned. Dodd, Zann, Buza, Sealy-Smith, Hough, and Britton all reprised their roles from the original series, while the others voice new roles: Disher voices Dr. Valerie Cooper, Potter voices Nathan Summers / Cable, Court voices Abscissa, Bayne voices Carl Denti / X-Cutioner, and Rubin voices President Robert Edward Kelly.
Ray Chase takes on the role of Scott Summers / Cyclops following the death of original voice actor Norm Spencer; Jennifer Hale replaces Disher as the voice of Jean Grey; Holly Chou replaces Court as Jubilation Lee / Jubilee, with Court previously stating that she would not return to the role and hoped an Asian-American actor would voice the character instead; A. J. LoCascio replaces Potter as Remy LeBeau / Gambit; Matthew Waterson voices Erik Lehnsherr / Magneto, following the death of David Hemblen; Gui Agustini voices Roberto da Costa / Sunspot; J. P. Karliak replaces Rubin as Morph; Isaac Robinson-Smith voices Lucan Bishop, replacing Philip Akin; Ross Marquand voices Professor Charles Xavier, replacing Cedric Smith; Gil Birmingham voices Forge following the death of Marc Strange; and Eric Bauza voices the Sentinels after the death of David Fox.
Meredith Layne was the casting and voice director for the series, responsible for casting actors and directing the voice recording sessions. New cast members were hired for instances where the original voice actor was not available or their voice was no longer appropriate for the character, and were intended to match the original performances. Recasting was also done to have more authentic representation (as with Court and Jubilee), because of specific vocal intonations (as with Cable to better highlight the "weird" father-son relationship with Cyclops), or for symbolic reasons (as with Disher now voicing Valerie Cooper). Regarding Disher's new role, DeMayo explained that Cooper delivers the series' thesis and he wanted Disher to be the one to present that since he felt "she was such the heart of the original series" and her original role as Jean Grey was "the epitome of empathy".
In February 2024, DeMayo said Theo James, who DeMayo worked with on the film The Witcher: Nightmare of the Wolf (2021), had been cast in a "fan favorite" role, later revealed to be Bastion. Reprising their voice roles from What If...? in the first season are Josh Keaton as Steve Rogers / Captain America and Michael Patrick McGill as Thunderbolt Ross.
Voice recording for the series began by November 2021, primarily taking place remotely over Zoom due to the COVID-19 pandemic. Chase and Hale recorded scenes for the third episode together in-person because of how much dialogue they share in that episode, but they said this was a rare occasion. Dodd revealed in February 2023 that he had started recording for the second season, and Zann stated in August 2023 that she had begun recording material for the second season as well. Bayne also returned for the second season. Despite the pandemic having less of an impact on subsequent seasons, voice recording continued to take place remotely for most cast members due to them being based in different locations.
