Tsuyu Asui, known as Froppy, possesses the Frog Quirk providing frog-like physiology. This grants her enhanced swimming, extreme jumping power, a strong prehensile tongue for grasping, wall-sticking capability, camouflage by adjusting skin color and temperature, and toxic mucus secretion from her stomach causing stinging or paralysis. Her Quirk also enables stomach storage for objects, though retrieval requires vomiting and causes nausea. Cold temperatures trigger hibernation, a significant weakness. Her hero costume features temperature-regulating neck gear to prevent hibernation and camouflage functionality matching her Quirk. A specialized winter variant includes insulation and enhanced goggles. Equipment variations encompass armored suits with technical enhancements, stealth-focused dark suits, and aquatic-themed designs. Academically, Tsuyu ranked 6th in U.A. High School mid-terms, demonstrating high intelligence. She exhibits analytical skills, deducing connections between Midoriya and All Might's Quirks during the U.S.J. Incident and devising team strategies like masking scents with mucus during the Joint Training Battle. Her calm, level-headed personality aids in crisis situations, such as coordinating escapes during the Flood Zone attack. Across media, including films like *Heroes: Rising*, Tsuyu engages in combat using Quirk-based techniques. These include deploying tongue whips for disarming or striking, combining acrobatic leaps with wall-clinging for mobility, creating adhesive nets for ensnaring, and using targeted venom sprays. She strategically employs camouflage for ambush tactics. Her fighting style incorporates environmental elements, gathering debris for projectiles or exploiting aquatic settings for enhanced mobility. Character development shows Tsuyu training to improve physical attributes, strengthening her tongue via rock climbing and boosting stamina to endure prolonged combat against enhanced foes. Post-*War Arc* narratives depict her operating independently as an infiltration specialist, undertaking clandestine missions outside official hero channels due to disillusionment with systemic limitations.
