Creation

Creation arrives in Chapter 14 and Episode 10 as the signature power of Momo Yaoyorozu of Class 1-A. Written as Sōzō in Japanese, it is filed as an Emitter Quirk whose effective range shifts entirely with whatever she decides to build.

The premise is matter fabrication on demand. Momo converts the molecular architecture of stored body fat into finished goods, which surface anywhere on her skin wrapped in a blue and pink glow. What emerges is indistinguishable from the genuine article, though she can alter the composition of the materials involved and hand a familiar object properties it would never normally have. Living things stay out of reach: humans and animals cannot be produced, but essentially anything else can, however elaborate its construction.

Kohei Horikoshi first sketched the ability for a seasoned professional and then handed it to a rookie instead, reasoning that something this versatile plays better in untrained hands. An early wording slip also needed patching, since the original ban on organic material would have made cloth and insulator sheets impossible, so the limit was narrowed to living beings.

Two requirements gate every fabrication. Momo has to grasp the atomic configuration of her target before it can exist, working mentally through the parts, then the materials, then the assembly, and finally the coating. She also has to pay for it in lipids, spending more as an object grows larger or more intricate, which makes serious eating a practical necessity rather than a quirk of character.

Neither her silhouette nor her surface area caps the result. Given deep enough reserves she can turn out something far bigger than herself, and she can generate items away from her body so long as some portion of the creation stays in contact with her. She also has the option of leaving a machine half-formed inside her while only the functional end protrudes, which matters when both hands are occupied or when she needs to swing the thing around in a hurry.

The costs bite. Building takes time, complicated pieces take more of it, and a relentless attacker who never lets her think can shut the Quirk down outright. Fumikage Tokoyami proved it at the U.A. Sports Festival: Dark Shadow pressured her over the boundary and out of the match, and Itsuka Kendo repeated the lesson at the Joint Training Battle, burying her under enlarged fists. Draining her fat stores too far leaves her underweight and frail, and any object whose composition she cannot picture down to the atomic level simply will not come.

Momo Yaoyorozu is the only holder. Her first flawless product came very young, after a run of failures, in the form of a Russian matryoshka doll, and the shape stuck: nesting dolls modeled on her own image now come almost instinctively, and she uses them as containers for other creations.

In combat she prefers to work close, snapping out poles, pikes, and similar melee hardware she handles well on offense, defense, and support, and reaching for cannons of assorted sizes when the distance opens up. Much of her output goes to teammates rather than herself. Her intelligence and her command of materials make her a natural strategist, building whatever a given problem demands, though the largest and most sophisticated constructions are held back for moments when she has time to plan and room to let them emerge, since those cases force her to leave her body exposed.

Two named moves stand out. Yaoyorozu's Lucky Bag uses a body-mounted cannon to fire a sack of support items downrange for allies to pick up. Electromagnetic Rail Gun pairs her with Denki Kaminari, whose Electrification powers the giant railgun she summons, hurling a projectile at an opponent at enormous speed. Her catalogue runs from staffs, swords, nets, and shields through flash bangs, gas masks, roller skates, catapults, and insulator sheets to dry ice, sedative canisters, infrared goggles, and a mechanical glider.
