Central to the emotional narrative is the queer romance between pansexual imp Blitzo and gay demon prince Stolas, which drives major episodes like 'Loo Loo Land' (babysitting amid their affair) and 'Ozzie's' (public humiliation of their relationship at a club run by queer characters). Additional queer identities include bisexual hellhound Loona and confirmed sexualities for others, integrated into the dysfunctional found-family dynamics of the I.M.P. assassin team. Episode 'Truth Seekers' directly confronts homophobic human cultists targeting Moxxie, framing prejudice as a conflict.

Creator Vivienne Medrano, who is queer, and queer voice actors like Brandon Rogers (Blitzo) emphasize authentic queer relationships, with media praising the show for normalizing them without tragedy. No race- or gender-swapping of established characters occurs, as it is an original IP with demon designs allowing organic diversity. There are no overt critiques of systemic oppression, patriarchy, or traditional norms beyond personal traumas and Hell's class divides. Minor anti-woke backlash exists in online criticism labeling stereotypical gay portrayals or juvenile bigotry handling, but it has not hindered massive YouTube popularity, indicating the elements are prominent but not foundational to the core premise of raunchy assassination comedy.
