Shuten Douji's portrayal in the animated special "Fate/Grand Carnival" preserves her core identity while embracing the series' comedic style. As one of Japan's Three Great Monsters, her origins adhere to Fate/Grand Order lore—including theories of descent from the dragon god Yamata-no-Orochi or Kuzuryuu, alongside her shared draconic heritage with Sakata Kintoki.

Her hedonistic personality prioritizes whimsical enjoyment, extravagant feasts, and intoxicating drinks, reflecting her canonical chaotic-evil alignment and disregard for conventional morality. The parody exaggerates these traits for humor, such as her participation in chaotic scenarios or a segment lampooning "Precure" where she comically advocates non-violence alongside Ibaraki-douji.

Relationships with Ibaraki-douji and Sakata Kintoki surface through shared appearances, echoing their main-series dynamics. Shuten's bond with Ibaraki fluctuates between mentorship and provocation, heightened in Carnival for absurdity during collaborative festival antics.

No unique character development or background expansion occurs in this adaptation. Her role utilizes existing lore—alcohol obsession, fascination with rare artifacts, and predatory charm—within the OVA's episodic, non-canonical structure. The adaptation introduces no new narrative elements beyond comedic vignettes. Her design remains consistent with Fate/Grand Order, featuring a purple-accented appearance, ornate kimono, and signature sake gourds.
