Momo

Momo is an 18-year-old girl, who's tall, with a "mature" physique, mainly shown by her huge breasts, large rear and thick thighs. She has long black hair, generally tied into a spiky ponytail with a large strand hanging on the right side of her face. Her eyes are big yet sharp, dark in color, and paired with short eyebrows set in a determined expression. 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 calf-length red boots with heels, which dip sharply down in the center, two gold utility belts around her waist, with the back holding her books on composition information, and another thinner one around the top 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. When she is just chilling in her room, her outfit consists of black leggings and a red T-shirt.

Momo's Quirk gives her the ability to create any non-living material/object from her exposed skin by transforming the molecular structure of her fat cells. To create something, she needs to understand the molecular structure of what the material/object is made of. The more Momo eats, the more material she has to work with, so she needs considerable food ingestion for her Quirk to be effective. However, it takes her a more extended period and more skin exposure to create large objects, to the point where she forces large objects through her costume, leaving it shredded, though she claims she can repair it. This aspect of Momo's Quirk is likely the reason for her slim figure, as she constantly burns her fat to create objects. It is also possible that this is a significant weakness because if she generates too much without replacing her calories, she can become weak and anemic.

Momo is a very prudent, dedicated person who is a natural leader. She is levelheaded and calm in dangerous situations, but she isn't above falling into a panic. Momo is very kind, polite, and relatively reserved, yet she can be blunt with her comments about people's mistakes and miscalculations, tending to be very direct and wishing to help her peers improve enough to become great heroes, such as when she tutored her classmates at her home. Momo shows further development as a selfless hero who gets inspiration from others while also taking the role of a leader in her class, thanks to her skills and intelligence. Because of her wealthy upbringing, she has a sensible and respectful attitude toward others, often being discouraged by discourteous behavior. 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 relatively 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 explains her lack of modesty in her costume.
