Creation

Creation is the Quirk used by Momo Yaoyorozu.

Description
Creation allows Momo to materialize different objects, such as weapons and tools, from any part of her body.

Apart from living things, Momo has the potential to replicate virtually any object, no matter how complex or advanced its structure may be. She only requires to understand the atomic configuration of said object in order to reproduce it: she first imagines the necessary parts, followed by the materials, then the assembling process and, finally, the coating. Momo's creations emerge from her body with a blue and pink glow and are otherwise no different from the regular objects they are based of, although she can customize the materials that form their composition, giving them whole new properties.

Momo doesn't necessarily have to completely dispense a creation from her body either, having the choice to materialize only half or more of its functional structure, while the rest remains within her person. This is useful for situations where she has to quickly maneuver said creation or herself around, or if both her hands are currently occupied with some other task.

Momo's body breaks down fat at a molecular level, which will then be re-used as material for her to shape into objects with her Quirk. Because of this, a considerable ingestion of food is necessary for Creation to be effective.

Weaknesses
Momo needs time to both make and use her items. Tokoyami defeats her in the Sports Festival by having Dark Shadow attack her continuously, giving her no time to think or go on the offensive herself.

The amount of objects that Momo can create depends both on the amount of lipids that she has in her body, as well as the size and complexity of the object she creates, spending more lipids the more difficult they are to create. Momo can end weakened if she is low in fat deposits.

In order to effectively create an object, Momo must have a deep understanding and knowledge of its atomic composition, which means she cannot create things she doesn't know how to create down to the atomic level.

Usage
Momo's first flawless creation was a Russian matryoshka doll, which she was able to materialize at a very early age after several failed attempts. Because of this, she can generate endless amounts of matryoshka dolls based on her image almost instinctively, further using those to store other creations of hers inside.

Momo prefers close-range combat, quickly producing basic melee weapons, such as metal poles and pikes, which she has skill wielding for offense, defense and support. For long range, she favors cannons of varying sizes. Her creations may be further used by her allies, giving them something to defend or help themselves with.

Because of her high intelligence, general knowledge about different materials and quick thinking, Momo is extremely capable of devising plans to solve almost any challenge she faces against, fabricating herself the necessary tools to do so.

Larger and/or more sophisticated creations tend to be reserved for situations where Momo has time to prepare a strategy and execute it. She has to leave her body more exposed in those cases, to allow room for said creations to arise.

Trivia

 * Creation is similar to the matter creation power of superhero from DC Comics. They both cannot affect organic life and need to know the chemical composition of the item in order to create it.
 * It was originally stated during the Quirk's introduction that Momo could not produce "organic material." Horikoshi noticed this oversight and later corrected it to simply "living beings," pointing out that, without organic fibers, clothes and insulator sheets would be impossible to make.
