Lancelot participates in the first episode of Fate/Grand Carnival, entering a competition among heroic spirits to resolve resource shortages. This event features various challenges, including sporting contests and elimination battles. His involvement occurs within the series' comedic and exaggerated narrative. In one instance, manipulated by James Moriarty, Lancelot dons Mash Kyrielight's "Dangerous Beast" outfit, an ill-fitting, revealing costume, intending to improve their relationship. This action causes Mash significant distress, necessitating psychological recovery afterward. Additionally, Lancelot briefly appears with Gawain and Tristan in the series' opening sequence, depicted celebrating before a poster featuring Swimsuit Altria, to her visible discomfort.
