Known by her hero name Creati, Momo Yaoyorozu originates from a wealthy Aichi Prefecture family. After attending Horisuma Junior High, she entered U.A. High School via recommendation, showcasing her exceptional abilities. Her Quirk, Creation, transforms lipid reserves into non-living objects through her skin, demanding extensive knowledge of molecular structures and careful caloric management. She developed this power through childhood practice with items like Russian nesting dolls. Momo stands 173 cm tall with long black hair typically in a high ponytail and a mature physique. Her hero costume includes a crimson sleeveless leotard for maximum skin exposure, red boots, and utility belts holding reference materials; a winter variant adds a red cloak. Post-graduation, her updated costume fully covers her torso and incorporates communication headphones. Initially confident as a recommended student, Momo ranked first in U.A.'s Quirk Apprehension Test and midterm exams while serving as Class 1-A's vice president. This confidence faltered after a swift defeat by Fumikage Tokoyami in the U.A. Sports Festival and an internship with Uwabami that emphasized her appearance over skills. She regained self-assurance during final exams paired with Shoto Todoroki against Shota Aizawa, using his encouragement to exploit Aizawa’s Quirk limitations for victory. Her S-tier intellect enables complex strategic planning and rapid crisis analysis. She excels academically, demonstrates teaching prowess through successful study sessions, and prioritizes support-based combat using weapons like staffs and cannons. Signature techniques include "Yaoyorozu's Lucky Bag" for supply deployment and the collaborative "Electromagnetic Rail Gun" with Denki Kaminari. Overusing her Quirk risks stamina drain and anemia. Key involvements span multiple conflicts: At the USJ Incident, she crafted weapons tactically despite costume damage. During the Forest Training Camp, she created a tracking device after Nomu injuries. In the Provisional License Exam, she led rescue operations through teamwork. At the Joint Training Battle, she commanded against Class 1-B and tied herself to Itsuka Kendo while unconscious. During the Paranormal Liberation War, she produced sleeping medicine to subdue Gigantomachia, nearly sacrificing her life. Post-war, she mourned Midnight’s death. Eight years later, she graduated U.A. and became the No. 19 Pro Hero. Momo speaks politely and formally, reflecting her upbringing. She remains calm under pressure but grapples with self-doubt after failures. While practical about costume exposure, she reacts with annoyance to vulgar behavior like Minoru Mineta’s antics. Supportive and resourceful, she hosts study sessions and aids peers, occasionally unintentionally referencing her wealth. Close bonds with Kyoka Jiro and Denki Kaminari formed during the USJ attack.
