The film lacks any visible LGBTQ+ characters or narratives addressing non-cisnormative identities. The story focuses primarily on sibling dynamics and monster mentorship.

A gender-balanced sibling duo provides a baseline for inclusion. While Abby serves as a co-protagonist, it is unclear if her role subverts traditional gender tropes.

There is no explicit mention of racial or ethnic diversity in the character descriptions. The cast appears to rely on standard animation archetypes without specific ethnic identifiers.

The narrative challenges the binary of good versus evil by redefining the role of monsters. However, the setting reinforces traditional social stability and Western genre conventions.

Herbert the Goblin's loss of will could serve as a metaphor for mental health struggles. Whether this is a deep portrayal or a simple caricature remains unconfirmed.
