TO BE HERO X does not feature any explicit transsexual characters or themes. While it includes ambiguous queer subtext in male-male relationships and strong female character arcs challenging gender norms, it does not extend to trans identities or communities, aligning with broader trends in Chinese animation regarding LGBTQ+ content.

The show features female characters, notably Min, who engage in combat. However, their victories against male opponents primarily rely on the use of significant superpowers, such as monster transformations or energy blasts, rather than skill, strength, or martial arts in close-quarters physical combat.

To Be Hero X is an original series without pre-existing source material or historical figures. Therefore, no characters have a prior established gender to compare against their on-screen portrayal, meaning no gender swaps occur.

The characters in "TO BE HERO X" are consistently portrayed as East Asian, aligning with their Chinese origins in the source material and setting. There is no indication of any character being depicted as a different race than originally established.
