Red Hare, a Rider-class Servant rooted in Chinese history and mythology, is celebrated as the legendary steed of the general Lü Bu. The adage "Among men, Lü Bu; among horses, Red Hare" cements their shared legacy of unmatched battlefield dominance. Renowned for loyalty to Lü Bu alone, Red Hare carried him through innumerable conflicts, enabling legendary feats like clearing a 30-meter-wide castle trench in a single leap. Within *Fate/Grand Carnival*’s comedic framework, Red Hare stands out as a rare low-rarity Servant fiercely prioritized by protagonist Ritsuka Fujimaru. This bond triggers Ritsuka’s intense protectiveness, erupting into rage if Red Hare’s care—especially feeding—is neglected. This devotion starkly contrasts the typical disregard shown toward other low-tier Servants, emphasizing Red Hare’s singular importance. Mythologically consistent traits define Red Hare’s design, blending Animal Characteristics and Demonic Beast classifications. Combat abilities mirror legendary agility: the Riding EX skill, a passive boost to Quick performance, and Noble Phantasm mechanics synergize with critical-hit tactics. Skills like temporary evasion, invincibility penetration, and critical-star generation prioritize swift, precise strikes. Though no narrative arc is elaborated in existing media, Red Hare’s role centers on comedic contrast—juxtaposing mythic grandeur with absurdity, exemplified by Ritsuka’s obsessive focus on the steed’s upkeep. Across appearances, the character’s core identity as Lü Bu’s mythic companion remains unwavering, with spin-offs and related media preserving this foundational lore.
