A good friend of mine and I wrote an X-Men screenplay for shits and gigs years ago- as fans, it was everything we wanted from an X-Movie. It had its own delightful little hypothetical life, fun stuff.
These designs were concept art for the sequel we were gearing up to write. Hasn't materialized yet unfortunately. And I never got around to designing any of the others besides Jean, Storm, and Nightcrawler.
The characters all bear the likeness of the actors we fancasted in the roles.
