Showrunner Beau DeMayo announced Morph as non-binary with a redesigned bald, mask-like appearance, and the character arc incorporates gender identity exploration; Rogue refers to Morph with they/them pronouns in episode 9. This change was defended by original series creators like Larry Houston as aligning with shapeshifting powers but drew pre-release backlash for injecting contemporary gender concepts into a 1990s-set story.

Casting and design choices extended to body diversity mandates confirmed by lead character designer Amelia Vidal. While core themes of mutant prejudice and coexistence echo classic X-Men allegory without new systemic oppression lectures, the prominent non-traditional identity focus and creator statements prioritizing inclusion elevate it beyond incidental elements. Audience reception showed clear divides, with online complaints labeling the Morph update as 'woke' and citing it alongside other redesigns as prioritizing messaging, though the season maintained strong viewership overall.
