Jaguar Man is a Pseudo-Servant formed by the fusion of Taiga Fujimura—a human connected to the Holy Grail and possessing an untamed demeanor—with an ancient Central and South American Divine Spirit linked to war, death, and revered by civilizations such as the Olmec and Aztec. This entity merges traits of a Jaguar Nagual, a guardian spirit tied to Tezcatlipoca’s mythology, manifesting as a Divided Spirit that seeks hosts marked by Holy Grail associations and primal vitality. Physically, the Servant maintains Taiga Fujimura’s human form but enhances it with jaguar ears and attire evolving across ascensions: early stages feature a whimsical onesie with paw-shaped accessories, while later forms adopt a refined black ensemble accented by a jaguar-patterned coat. Combat gear transitions from a comical paw-club to a naginata, underscoring adaptability in battle. The personality blends mischievous humor, feline-themed wordplay, and Taiga’s inherent cheerfulness, tempered by prideful aloofness. Trust is earned incrementally through persistent effort, metaphorically represented by accumulating "Jaguar Stamps" to gain her recognition. Within the Babylonia Singularity, Jaguar Man initially antagonizes protagonists under Quetzalcoatl’s command, recruiting sacrifices until defeated. Persuaded by strategic praise, she allies with Ritsuka Fujimaru, contributing tactical expertise in jungle navigation and terrain-based strategies during conflicts against Quetzalcoatl and Tiamat. A recurring rivalry with Quetzalcoatl emerges, blending competitive clashes with reluctant camaraderie rooted in shared jaguar symbolism. In comedic adaptations like *Fate/Grand Carnival*, her traits amplify for humor—exemplified by deploying the "Jaguar Kick" to comically launch Cú Chulainn skyward. These portrayals preserve core attributes: a carefree demeanor, insistence on wearing an actual jaguar pelt, and interactions emphasizing chaotic whimsy. Abilities include heightened agility, forest-stealth proficiency, and Noble Phantasms such as *Great Death Claw* for devastating strikes and *Jaguar in the Black* for night-based ambushes. Skills like *Jaguar Punch* and *Jaguar Eye* exploit jungle environments, mirroring mythological roots. Strategic limitations arise from lower magical reserves compared to full deities, balancing divine heritage with pragmatic combat utility.
