Scáthach, known as the Queen of the Land of Shadows from Celtic mythology, is a Lancer-class Servant in the Fate series. In her Piercing Bunny variant from Fate/Grand Order, she dons a revealing black bunny suit with red accents, high heels, and fishnet stockings, armed with her iconic twin spears, Gáe Bolg. Despite the playful attire from a swimsuit event, she retains her formidable combat prowess and immortal nature, having trained countless heroes like Cú Chulainn in the Land of Shadows. As an ageless warrior queen, she seeks worthy opponents and eagerly instructs Servants in battle techniques, blending her serious demeanor with the event's whimsical theme.
