Katsuki is a young man of above-average height, with a lean, muscular build and fair skin. He has short, spiky, ash-blond hair with choppy bangs that hang over his eyebrows. His eyes are sharp and a bright scarlet.

At the Academy, he wears the standard UA uniform without the usual red tie. Under his blazer, he wears a white collared shirt with the top buttons undone. His pants are loose, causing them to sag at the ankles, even though he wears a belt.

His hero costume consists of a tight, black, muscle-hugging T-shirt with an orange "X" in the center, forming a V-neck. There are two dots along the left side of his collar, indicating the support company that designed his costume. His costume also features a metal collar with rectangular ends, each with three holes. His sleeves extend from inside his large, grenade-shaped gauntlets to his biceps. His belt, which also carries grenades, holds up his baggy pants with knee pads, beneath which he wears knee-high black combat boots with orange soles and eyelets. His mask is jagged and black, and as it wraps around his eyes, a large, orange-rimmed flare protrudes from each side.

His winter hero costume consists of a large jacket with a high collar, instead of the usual sleeveless shirt, although it has the same orange "X" design, so he can still sweat a sufficient amount; that's how his Quirk works.

He has a superiority complex, always wanting to be the best at everything and trying to prove it at all costs; however, even with these traits, he knows how to admit when he has been defeated, as was demonstrated during the Test Battle.

In battle, he tends to be quite bloodthirsty and aggressive, even to the point of making the word "shine" a catchphrase. His brutal fighting style is on full display in the battle test, where he mercilessly attacks Izuku and recklessly destroys everything in their enclosed space. Despite this, and regardless of his lack of compassion, he has been recognized for his enormous talent and skill in combat, as he not only attacks and destroys, but is also capable of using his Quirk to move through the air.

Explosion (Bakuha): Katsuki's Quirk allows him to secrete nitroglycerin through the sweat of his hands and detonate it at will to create explosions. The more Bakugo sweats, the stronger his explosions become. As Best Jeanist noted, Katsuki has a strong understanding of his Quirk's applications. He usually uses small, powerful explosions from his hands not only to blow up his opponents but also to propel himself and move through the air, among other non-combat uses. He can maintain the sequence of his explosions long enough to destroy a giant ice wall created by Shoto.

The explosions are powerful enough to send opponents flying with little time to react. He can use them quickly enough to evade incoming attacks, even in mid-air. His most powerful explosion to date (without the need for grenade gauntlets) was used to completely destroy Ochaco Uraraka's meteor shower, sending her flying with the subsequent shockwave that shook the entire Sports Festival stadium. He later uses it several times in quick succession when facing All Might in the physical test of the final exam.

Katsuki does suffer some impact from his explosions due to their magnitude, but the overall effect is minimal given his physical conditioning. He can trigger constant explosions around him without feeling any negative repercussions, even after many powerful blasts. However, excessive use can result in Bakugo injuring his arms from the force of the powerful explosions.

Another drawback of Katsuki's Quirk is that he is unable to use his explosions in areas filled with flammable gas, as his explosions would ignite the gas and spread it even further.

General Abilities: Katsuki has proven to be one of the strongest students in Class 1-A, both physically and theoretically. Many pro heroes have remarked on his immense skill, including Shota Aizawa, All Might, and even the Number 3 Hero, Best Jeanist. The League of Villains has also recognized his strength and attempted to capture him, but their efforts were unsuccessful in recruiting him.

Enhanced Strength: Katsuki possesses superior physical strength compared to the rest of his classmates, having practiced for years. He has fought on par with Izuku when using his Quirk, and has also been able to pressure and subdue Shoto Todoroki during their battle at the festival.
Sharp intellect: Despite having an aggressive and childish character, Katsuki has shown on many occasions to be intelligent, strategic and astute, such as when he managed to discover Kurogiri's weak point and Fumikage's weakness.
