Momo Yaoyorozu attends U.A. High School, securing admission through official recommendations based on her exceptional abilities. She holds the position of vice president for Class 1-A. Born into significant wealth, her privileged upbringing granted early access to resources for Quirk training, including the use of Russian matryoshka dolls to refine her skills. Despite her family's status, she displays no arrogance, focusing intently on personal merit and academic achievement. Physically, Momo possesses a tall, mature build. Her long black hair is usually styled in a spiky ponytail, with a single bang framing the right side of her face. Her hero costume consists of a red sleeveless leotard that exposes skin from her collarbone down past her navel, complemented by red heeled boots and functional gold utility belts. This design maximizes skin exposure necessary for her Quirk; an initial, even more revealing costume concept was modified due to restrictions. Winter adaptations add a red cape secured with a gemstone clasp. Post-graduation, her costume evolves to fully cover her torso and incorporates communication headphones. Academically, Momo consistently ranks first in Class 1-A. She excels particularly in molecular science, a direct requirement of her Quirk. She hosts study sessions at her home, significantly boosting classmates' performance and preventing failures on written exams. Her leadership extends beyond academics; she coordinates strategies in combat scenarios and mentors peers, though her feedback regarding their mistakes can sometimes be blunt. Her Quirk, Creation, enables the molecular restructuring of lipid cells into non-living objects via exposed skin. This power requires exhaustive knowledge of atomic structures and consumes body fat, demanding a high-calorie intake. Limitations include slower creation times for larger items, vulnerability during extended materialization, and physical depletion risking anemia. Her training focuses on accelerating production and improving lipid efficiency. In combat, Momo favors tactical ingenuity over direct confrontation. She wields weapons like bo staffs proficiently and creates items tailored to specific situations: insulated sheets during the U.S.J. incident, cannons in the Sports Festival, and replicas of Eraser Head's scarf. Signature techniques include "Yaoyorozu's Lucky Bag," firing support items from a cannon, and the collaborative "Electromagnetic Rail Gun" with Denki Kaminari. Her equipment includes a lexicon, the "Yaoyorictionary," detailing molecular structures. Character development reveals an initial confidence shaken by rapid losses to Fumikage Tokoyami in the U.A. Sports Festival and superficial internships with Uwabami, who prioritized Momo's appearance over her skills. This eroded her self-worth until Shoto Todoroki's encouragement during final exams restored her belief in complementary strengths. Later arcs showcase resilience; against Itsuka Kendo, she orchestrates diversionary tactics despite close-combat disadvantages, and on Nabu Island, she coordinates artillery assaults against Nine's group. Post-U.A., she achieves the rank of No. 19 Pro Hero. Momo's personality blends analytical rigor with supportive enthusiasm. She remains calm under pressure but can panic when comparing herself to peers. While sensitive to vulgar behavior like Minoru Mineta's advances, she exhibits no modesty concerns regarding her costume's exposure, viewing it purely as functional necessity. Occasional "bouncy" excitement surfaces when aiding friends or studying. Trivia notes her censoring during the U.S.J. arc, the meaning of her family name "Yaoyorozu" ("eight million"), her placements in U.A.'s midterm popularity polls (11th initially, rising to 7th), and her association with red-crowned crane motifs.
