Mother: Mitsuki Bakugo (((She is very similar to her son physically and in character))) Father: Masoru Bakugo (((Calm character and doesn't resemble his son)))

Furthermore, because his Quirk relies on his sweaty hands, it's more difficult for him to use it in colder climates. Without the sweat on his palms, he can't utilize his Quirk to its full potential.

Explosion (Bakuha): Katsuki's Quirk allows him to secrete nitroglycerin through the sweat of his hands and detonate it at will to create explosions.[7] The more Bakugo sweats, the stronger his explosions become.[8] As noted by Best Jeanist, Katsuki has a strong understanding of his Quirk's applications.[9] 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.[10] The explosions are powerful enough to send opponents flying with little time for them to react.[11] He can use them quickly enough to evade incoming attacks, even in mid-air.[10][12] 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 away with the subsequent shockwave that shook the entire Sports Festival stadium.[13] He later uses it several times in a row 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.

Katsuki is a young man of 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. During his internship with Best Jeanist, he wore a pair of tight blue jeans with his hero costume, instead of his usual baggy pants. His hair was also styled and parted to the side during this time.

However, his beliefs differ: Katsuki feels that a hero should never stop fighting or give up, regardless of the threat they face, and that always winning is the mark of a true hero. Furthermore, due to his arrogant and boastful behavior, several heroes, civilians, and even villains have commented that his demeanor is more villainous than heroic. Nevertheless, Katsuki is unwavering in his goal of becoming a hero, having flatly rejected Tomura's invitation to join the Alliance of Villains.

At first, when he was defeated, he went into a kind of shock, and in addition to this, he does not admit that he surpasses others when the fight ends without him delivering the final blow, like when he fought against Ochaco Uraraka in the Sports Festival and they decided to end the confrontation before he finished Ochaco. As the story has progressed, Katsuki's personality has gradually changed. Initially, he was very arrogant and intolerant, but little by little, he has softened his attitude to the point of implicitly showing concern for others, as demonstrated in the provisional hero license exam when he reduced his explosions to avoid harming Denki and Eijiro, or when he waited for Eijiro to return from the battle against the Eight Precepts of Death. He has also shown empathy, as seen in Shoto's case when he secretly listened to his past.

Katsuki presented himself as a very impulsive, aggressive, and arrogant person, as seen in the way he treated Izuku, whom he constantly violated physically and psychologically, even telling him to kill himself, showing his bastardly attitude. 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 demonstrated during the Trial Battle, when at the entrance of the academy, Izuku tried to explain to him that his Quirk One For All came from another person, and Katsuki interpreted that he was mocking him, so he tried to shut him up by saying that he simply beat him.[4] 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 the enclosed environment they were in. Despite this, and regardless of his lack of compassion, he has been recognized for his enormous talent and fighting prowess, as he not only attacks and destroys, but is also able to use his Quirk to move through the air. This has been noted by Momo Yaoyorozu, Shoto Todoroki,[5] and even All Might.[6] Although he isn't the hero with the best character, as the story progresses, his behavior slowly begins to mature, becoming less rude and arrogant. As the year goes on, he begins to trust and cooperate with his classmates, whom he previously rejected because he wanted to do everything on his own, neither helping nor expecting help. That egomania cost him several mistakes in class that led to defeat or being very close to it, were it not for the fact that he had to reluctantly cooperate with his classmates. His inspiration to become a hero was the same as Izuku's, the symbol of peace All Might.
