Tiger's Eye began as a tiger within the Dead Moon Circus before the Amazoness Quartet, under Queen Nehelenia’s orders, transformed him into a humanoid. As a member of the Amazon Trio with Fish Eye and Hawk’s Eye, he hunted the Silver Crystal by trapping Sailor Guardians in nightmares through psychological tactics like gaslighting, preying on their insecurities. In the manga and *Sailor Moon Eternal*, he focused on Rei Hino (Sailor Mars), luring her into a hall of mirrors to exploit unresolved trauma from her father’s abandonment. He crafted illusions of her childhood self yearning for marriage—subtly implicating himself—to destabilize her resolve. Rei countered by piercing the deception with aid from her raven familiars, Phobos and Deimos, and vanquished him with her Mars Flame Sniper. Unlike other iterations, he retained his humanoid form throughout the confrontation. The 1990s anime diverged, depicting him hunting Dream Mirrors while favoring young female targets. Armed with a whip, he sacrificed his human form to repair a shattered Dream Mirror, resulting in his demise. Pegasus later resurrected him and the Trio by gifting them new Dream Mirrors, enabling their existence as fully human. This version highlighted his theatrical demeanor and tendency to address his Lemures with playful endearments. Musicals like *Shin Densetsu Kourin* presented him as effeminate, using the term "okama" to describe his cross-dressing persona. He engaged in gossip, comedic antics, and even attempted to kiss Fish Eye. Naoko Takeuchi’s notes revealed his aspiration to become a legendary rockstar—a detail briefly acknowledged in the manga and expanded in *Eternal*. All adaptations maintained his feline motifs and quartz-themed identity, with his name and appearance mirroring the golden-brown striations of the tiger’s eye gemstone. Though his strategies and fates shifted across versions, his core role as a cunning manipulator weaponizing psychological fragility remained unchanged.
