Katsuma is a teenage boy of average height with freckles all over his body and curly brown fluffy hair with hazel eyes, with an addition of a chipped tooth when he flashes a smile. He also wears a necklace with a floral charm, identical to the bracelet his older sister Mahoro Shimano, wears.

He wears the normal U.A. uniform during school hours, the second button of his blazer undone and he wears dark brown shoes. He also carries a small, brown messenger bag that has a pin of the Pro Hero Edgeshot's face fastened onto the strap.

His Quirk
Cell Activation (細さい胞ぼう活かっ性せい Saibō Kassei): Katsuma's Quirk allows him to speed up the activity of Cells within one's body, including his own. This makes it to where he can heal wounds and even improve bodily performance. Over time and with further training, Katsuma's Quirk has evolved to where it is capable of much more than simple regeneration. This includes the ability to either enhance or debilitate the Quirk Cells within another person's body, either making their Quirk much more powerful, or much weaker for a short time. He is also capable of enhancing the cells within his own body in order to drastically improve his own physical capabilities for a brief time. The longer Katsuma uses his quirk, the more stamina it takes. If he stops in time, it will only cause drowsiness and possibly insomnia. If he overexerts himself, he might pass out or have a panic attack. Also, if used in the wrong way, the same powers can be used to accelerate cancerous tumors, degenerative diseases, and other harmful conditions.

a Quirk is a unique superhuman ability possessed by a majority of the population. These abilities manifest in individuals around the age of four and can range from simple enhancements to incredibly powerful and complex capabilities.
Quirks play a central role in the story, shaping the society and its heroes and villains. They are diverse, with a vast array of manifestations and applications, often reflecting the user's personality or aspirations.
There are various categories of Quirks:

• Emitter Quirks: These are the most common type, allowing users to generate and manipulate various substances or phenomena, such as fire, ice, or electricity.

• Transformation Quirks: These Quirks enable users to temporarily alter their physical form or specific body parts.

• Mutant Quirks: These Quirks permanently change the user's body, granting them unique features or abilities from birth.

• Accumulation Quirks: These Quirks involve storing and releasing energy or power, often requiring a period of charging or buildup.

Quirks are often hereditary, with children inheriting a combination of their parents' Quirks or developing a new Quirk entirely. Some individuals, known as "Quirkless," are born without any special abilities.
The concept of Quirks in MHA explores themes of individuality, power, and responsibility, as characters learn to master their abilities and use them for good or ill in a world where superpowers are the norm.
