Setsuna Tokage, hero name Lizardy, stands as a strategic prodigy within U.A. High’s Class 1-B, wielding the fragmentation Quirk *Lizard Tail Splitter*. This ability lets her divide her body into fifty telekinetically controlled segments, operating autonomously before reintegrating—a process taxing her stamina. Her biomimetic costume, grown from her cells, seamlessly regenerates with each reconstitution, ensuring operational readiness. Born in Saitama to a family with reptilian Quirks, her father’s detachable limbs and mother’s Utahraptor-inspired traits shaped her dual passions for paleontology and heroics. A former gyaru fashion enthusiast, she redirected her energy toward combat mastery by U.A.’s entrance. At the U.A. Sports Festival, she deliberately placed 39th in the obstacle race to analyze Class 1-A’s tactics before facing elimination in the cavalry round. During the Joint Training Battle, she orchestrated a multi-phase strategy capitalizing on Katsuki Bakugo’s perceived individualism, deploying decoy fragments to scatter opponents. Bakugo’s battlefield intuition overturned her maneuvers, exposing her overreliance on rigid planning—a flaw she later remedied through adaptive combat drills. Interning under Pro Hero Majestic refined her predictive combat analytics, skills pivotal during the Paranormal Liberation War. There, she spearheaded efforts to immobilize Gigantomachia by dispersing Momo Yaoyorozu’s sedative vials across the battlefield. Majestic’s subsequent death tested her resilience, yet she channeled grief into composed leadership. Post-graduation, she ranked as the No. 22 Pro Hero, adopting a blonde aesthetic and upgraded gear. Leveraging her Quirk’s adaptability for covert operations and disaster response, she balanced solo missions with team-based tactics to conserve stamina. Within Class 1-B, she fostered unity through shared strategy forums and mentorship, maintaining lifelong camaraderie with childhood ally Juzo Honenuki. In the *World Heroes’ Mission* crisis, she deployed alongside Momo Yaoyorozu in Singapore, utilizing fragmented clones to plant sensors and neutralize Humarise’s Trigger Bombs—proving her Quirk’s scalability in global emergencies. Personality-wise, she merges calculated wit with battlefield psychology, disorienting foes through taunts or precision strikes against weaknesses. Off-duty, she maintains a relaxed, approachable demeanor, openly acknowledging missteps while encouraging peer collaboration—a duality cementing her reputation as both a shrewd tactician and grounded ally.
