Jaguar Man is a Pseudo-Servant formed by a Divine Spirit from Central and South American mythologies possessing Taiga Fujimura's body. This spirit embodies the jaguar, revered as a symbol of war and death in Olmec and Aztec civilizations, specifically syncretizing aspects of the Jaguar deity and the Nagual—a supernatural guardian linked to Tezcatlipoca. Taiga was chosen as the vessel due to her inherent Holy Grail connection and "wild" fate aligning with the Jaguar's nature. Her appearance retains Taiga's features but adds jaguar ears. Initial ascensions feature a jaguar-themed onesie over a striped shirt, tiger-print shoes, and a "frightening club" resembling a cartoonish jaguar paw. Her third ascension adopts a black outfit with a jaguar-print coat, jeans, and a golden necklace, replacing the club with a naginata; her eyes shift from brown to red. Whimsical, mischievous, and brightly friendly, her personality heavily reflects Taiga's traits. She frequently uses cat puns and exhibits persistent fixation on teasing targets. Despite her playfulness, she is prideful and values earned trust: Masters receive daily "Jaguar Stamps," with accumulated stamps signifying progression toward becoming her "Jaguar-mate" (or Tezcatlipoca-mate). She maintains a rivalry and one-sided friendship with Quetzalcoatl, often acting as her subordinate despite Quetzalcoatl's annoyance. She vaguely recognizes other Pseudo-Servants like Parvati (in Sakura Matou's body) and Senji Muramasa (in Shirou Emiya's body), often staring at them. She feels partially responsible for EMIYA's delinquent-like demeanor, though the exact reason eludes her. In the Babylonia Singularity, Jaguar Man initially appears as a Stray Servant allied with Quetzalcoatl. She confronts Ritsuka Fujimaru's group multiple times in southern jungles and Ur, leveraging her agility and jungle mastery to force retreats. She assists Quetzalcoatl in collecting "sacrifices" (Uruk soldiers later revealed revived, not killed) for her army. After a decisive defeat by Ritsuka's party—aided by Ishtar—she is persuaded through flattery to switch allegiances. She then guides the group to Eridu, aids in countering Quetzalcoatl, and clarifies the latter's motives. Post-alliance, she navigates tensions with her former werejaguar subordinates. As a Divine Spirit Servant of moderate power, classified as lower-grade, her magical energy cost is reduced. Her parameters are Strength (C), Endurance (C), Agility (B), Mana (E), Luck (B), and Noble Phantasm (B). Key skills include **Jaguar Punch** (Divine Protection of the Jaguar, granting fear/pain immunity and combining Valor/Instinct effects), **Jaguar Kick** (temporary Strength boost via Monstrous Strength), and **Jaguar Eye** (enhancing forest/jungle capabilities, including frequent Noble Phantasm access). Her Noble Phantasms are **Great Death Claw**, an anti-unit attack transforming her club into a giant weapon for unavoidable strikes, and **Jaguar in the Black**, a nocturnal barrier granting stealth and attack modifiers to herself and allies. Passive abilities include Magic Resistance (A), Mad Enhancement (E), and Divinity (A), though Ana notes her divinity is lesser than Quetzalcoatl's, likening her to a "paper tiger."
