She is voiced by Marina Inoue in the Japanese version of the anime, and by Colleen Clinkenbeard in the English version of the anime.
Momo is a fairly tall teenage girl with a rather mature physique, considering her age. She has long black hair that is normally tied into a spiky ponytail with a single bang hanging on the right side of her face and onyx eyes that point slightly inwards, which seems to resemble a cat.
During school hours, she wears the standard female uniform which consists of a gray blazer with blue-green stripes, a formal white shirt, red tie, blue-green pleated skirt, black knee socks, and brown shoes.
Her hero costume consists of a high-collared, sleeveless crimson leotard with silver lines at her waist and around her arms, which is open to expose her skin from her neck to just below her navel. She sports short crimson boots which dip sharply down in the centre, and two gold utility belts around her waist, another, thinner one around the top portion of her chest, below her shoulders. The design choice allows her to create items from as many points in her body as possible, as her Quirk can only be used if her skin is exposed.
During the winter months, she wears a long, high-collared red cape, a ring going around her neck with a large gemstone at her throat.
Momo is a very prudent and dedicated girl who acts as a natural leader. She is generally level-headed and calm in dangerous situations, but she isn't above falling into a panic. Momo can be blunt with her comments about people's mistakes and miscalculations, tending to be very honest and wishing to help her peers improve enough to become great heroes, like tutoring them on her home. Momo shows further development as a selfless hero who gets inspiration from others, realizing the important thing is to focus on saving her and help them out at that moment even if it means losing her provisional hero license.
While originally confident in herself, Momo's pride was crushed after her rapid loss to Fumikage Tokoyami in the U.A. Sports Festival and the comparisons she made between Shoto Todoroki and herself, starting to lose confidence in her own ability to make quick choices on practical situations. It was further damaged during Uwabami's shallow internship, believing the heroine chose her despite being "an unworthy student" and tried to find deeper lessons to reassure herself. Thanks to Shoto's encouragement on their final exams, Momo regained confidence on her quick-thinking, learning people have different skills and sometimes can complement each other. Even when she is weakened and trapped by her opponents, she doesn't give up and shows the increase of her Quirk output, ultimately defeating her enemies.
When she displays excitement towards pass time with her friends or help them, Momo becomes upbeat and eager. She also tends to accidentally reveal how rich she is, yet most people understand she doesn't do it out of malice. Despite her mature mannerisms, she occasionally finds herself roped into silly situations such as cheerleading, although she rarely expresses much enthusiasm in doing so.
Momo typically takes adverse situations in stride, expressing little concern for losing most of her clothing in battle; as she knows how to construct another set, and would have made her costume even more revealing were it not for restrictions on exposed skin in a costume. However, this often makes others think of her as an exhibitionist. Ironically, she is rather innocent and sensitive to vulgarity and rude mannerisms, constantly frustrated by sexual advancements from Minoru Mineta and Katsuki Bakugo's crude attitude. This innocence shows that she has a somewhat casual, natural and non-lewd view toward nudity, which allows for her lack of modesty in her costume and the fact that she didn’t care when it was torn while fighting the villains invasion of the Unforeseen Simulation Joint.
Overall Abilities: Momo is a recommended student, which implies that she must have a very good level of skill. Her abilities earned her 1st place in the Quirk Apprehension Test, an impressive feat considering almost all her classmates had at least one superhuman result and the end result was cumulative of all eight tests. Momo was able to hold her own against Fumikage Tokoyami, for short period of time during the U.A. Sports Festival.
- Bukijutsu: Momo can skillfully wield several weapons to use against her opponent, for both offensive and defensive purposes, primarily bo staffs. Her bojutsu is quite remarkable, which allows her to knock out a large group of villains, as shown during the assault on the U.S.J.
Genius Intellect: Momo is ranked to have S-class intelligence, being a genius. Her analytical skills are strong, easily devising strategies and plans in battle and urgent situations, which she has no trouble putting in motion due to her Quirk's versatility. Academically speaking, Momo is highly efficient, having been ranked 1st place in the mid-terms of her class, and understanding the composition of anything she wishes to create using her Quirk. The latter is a complicated task for even the simplest materials. Regardless, Momo commonly uses the objects from her Quirk to provide auxiliary support for her allies, as well as blindside her opponents, making her a very crafty individual, and reliable comrade. What she lacks in raw strength and destructive power, she makes up for with her ingenuity. When she was paired with Shoto Todoroki, against Eraser Head for the Final Exams, she realized that the Eraser Hero's Erasure Quirk has a smaller time limit due to the injury he received from Nomu at U.S.J, and capitalized on that small interval to blindside Eraser Head and secure victory for her and Shoto.
During the Joint Training Battle, Momo demonstrated her ability to anticipate unexpected circumstances; she took notice of the opposing team having a two-fold plan. Shoto even stated that thinking and planning under pressure or in times of crisis is Momo's area of expertise. She also has good judgment, being fully aware that once Itsuka Kendo took the match to her own strong suit: close-quarters combat, Momo herself wouldn’t stand a chance. Even when overpowered by Itsuka, Momo effectively blindsided the big-fisted heroine by creating a cannon at point-blank range, making it look like she was going to fire it at the latter. Taking advantage of Itsuka's startled reaction, Momo quickly turned the cannon in another direction and fired her lucky bag over the wall of letters to give extra support to her teammates. Even though Momo provided assistance to her teammates, she was incapacitated by Itsuka, but not before the recommended student managed to tie herself to the latter before losing consciousness.
- Teaching Ability: Momo is considered an extremely good tutor by her peers, holding several study classes for other members of Class 1-A. The results have been noticeable judging by the U.A.'s First Term Final Exam, where none of the low-grade students failed in the written exam.
