Casting remains true to the original ensemble of fantastical characters voiced by consistent actors, featuring organic diversity through non-human species, colors, and personalities rather than forced DEI mandates or swaps. The prominent 'Stakes' miniseries delves into Marceline's vampire backstory, confronting past trauma and relationships—including subtle subtextual hints of her history with Princess Bubblegum—but these are incidental to the action, horror, and character-driven plot, not lecture-like messaging on identity politics or social justice.

Other episodes like 'Princess Day' touch lightly on gender dynamics among princesses via comedic side character Lumpy Space Princess (noted as lesbian in canon but played for humor), but such elements do not drive narratives or dominate arcs. No explicit critiques of systems, patriarchy, or traditional norms; no creator statements emphasizing activism under showrunner Adam Muto.

Audience reception highlights creativity, Emmy wins, and trippy fun without significant backlash labeling it 'woke' or prioritizing message over entertainment. This season exemplifies pure, engaging fantasy for all ages, unmarred by contemporary social justice activism.
