The X-Men have returned.

“Every design choice is actually a clue to the storylines we’re doing,” DeMayo says.

“Nothing is arbitrary.”

Beast (voiced by George Buza), Rogue (voiced by Lenore Zann), Morph (voiced by JP Karliak), Cyclops (voiced by Ray Chase), Wolverine (voiced by Cal Dodd), Gambit (voiced by AJ LoCascio), and Bishop (voiced by Isaac Robinson-Smith) in Marvel Studios' X-MEN ‘97.

The clue from the legacy costumes is all about nostalgia.

Was it truly simpler back then, or were we just more naive?

“Well, finally, you’re getting that ‘more.’

You’ll be able to find out what happened next.”

Its always interesting to take Xaviers dream and turn it on its head, DeMayo says.

It was so much more simplistic than it is today.

[The X-Men] spent years telling humanity to embrace the future, walk into the future together.

What happens when they get hit with a future they didn’t see coming?

EW can also exclusively confirm the cast of veteran and newcomer actors joining the sequel series.

(James voiced lead character Vesemir, and DeMayo wrote the movie.)

There’s still a place for other veteran actors ofX-Men: The Animated Seriesin the sequel.

Chris Potter, the original Gambit, is now playing Cable/Nathan Summers.

Lawrence Bayne, the original Cable, is now playing Carl Dentil/X-Cutioner.

Ron Rubin, the original Morph, is now playing President Robert Edward Kelly.

Finally, Alyson Court, the original Jubilee, is now playing Abscissa.

There were also more symbolic reasonings, as with Jean Grey.

DeMayo wanted the actress behind his favorite X-Men character to deliver the thesis ofX-Men ‘97as Valerie Cooper.

“Jean Grey is the epitome of empathy,” DeMayo says.

“She is the one person who truly understands the sacrifice that is necessary to be an X-Man.”

(See the Phoenix Saga from the original series.)

“Val has a very interesting arc in our first season, I will say.

I remember when I first met with Catherine.

What is that thesis?
