Katsuki Bakugo

Katsuki Bakugou (爆豪勝己) is a student of Class 1-A and a deuteragonist of the series.

Appearance
He has ash blond spiky hair and orange eyes.

His hero costume is composed of a fitted black sleeveless V-neck tank top with an orange X with the top half borders his shirt collar. His costume also has a seemingly metallic neck brace fashioned and used as a collar with three holes in both sides. His sleeves reach from within his large grenade-like gauntlets to his biceps. His belt, which also carries grenades, holds up his baggy pants with knee guards. He occasionally wears his hero mask that has large, flare-shaped cloth.

Personality
Katsuki is a very crude and aggressive person that has a tendency of bullying Izuku Midoriya, who he also treats in some ways as a rival.

Brutal and bloodthirsty, he smiles eerily when he's put into battle. While battling, his personality reflects his fighting style. His brutish way of fighting is shown through the Battle Trial: mercilessly assaulting Izuku and having no regard for nearby objects, merely destroying them with his power. Despite this, he's quite talented in fighting, able to use his Quirk to not only destroy but to maneuver around the battlefield.

While not the most mentally stable hero-in-training, nor having the image of one, he knows who his enemies and allies are. Cold to his allies, though not to the extent of friendly fire, but colder and brutal to his enemies. As the series progresses, his outbursts become less aggressive, usually becoming more comical, as he mostly gets angry at even small things like teasing. With that in mind, Katsuki seems to mature slowly but is still quite cold and distant.

He has a superiority complex and wants to be first and the best at everything. He doesn't like when people look down on him, as if they were superior to him; thus, it diminishes his already short fuse. Despite his extreme arrogance, he also thinks of people such as Izuku Midoriya as an obstacle on his path to becoming the greatest hero. Because of his complex, he's implied to be anti-social; He also seems to have bad memory, as he couldn't remember anyone's Quirks despite being in Yuuei for some time, and couldn't remember Eijirou's name. But after his fight with Ochako, he used her name, implying that he remembers the names of people who give him a challenge or who's ability he respects.

Ironically, his inspiration for becoming a hero was the same as Izuku's, the Symbol of Peace All Might. However, their beliefs differ, as Katsuki feels a hero should never stop fighting or give up, regardless of the threat they face, as he believed that always winning is the mark of a true hero.

Quirk and Abilities
Explosion (爆破 Bakuha): Katsuki's sweat is nitroglycerin-like, and Katsuki can use it to create explosions. The more Katsuki sweats, the stronger his explosions become. So far, the signature use of his Quirk is through his hands; usually between punches or to shroud his fist with explosive energy. It is unknown if he can create explosions from any other part of his body. His most powerful Explosion so far (without the need of the Grenadier Bracers) was able to completely destroy Ochako's meteor rubble shower, knocking her down onto the ground at the same time and caused a shock wave that was felt throughout the stadium. Due to his extensive combat knowledge and creativity, this makes it a very deadly and versatile Quirk.

One 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 cause chaos.

Moves

 * Blast Rush Turbo (爆速ターボ Bakusoku Tābo): Katsuki throws his hands backwards and then causes an explosion in his palms, to propel himself. This move was first used during the 50-meter dash of the quirk apprehension test in Chapter 6. This move can also be used to achieve a pseudo form of flight, as Katsuki used this move to fly over the giant robots during the Obstacle Race during the Sports Festival.
 * Stun Grenade (閃光弾 Sutan Gurenēdo): Katsuki creates a sphere of light with his hands. The sphere of light implodes, causing an explosion around Katsuki, damaging anything in Katsuki's vicinity. This move was first used in Chapter 42.
 * Howitzer Impact (榴弾砲着弾 Hauzā Inpakuto): Katsuki dashes into the air and creates two Explosions in his hands. While in the air, Katsuki spins himself around, building up momentum for his Explosions. After spinning himself around and gathering momentum for his Explosions, Katsuki fires an Explosive tornado at his opponent. This move was first used in Chapter 43.

Enhanced Strength: Katsuki possesses an above average physical strength, as he was able to fight on par with Izuku even when the latter is using his Quirk. He was also able to pressure and overpower Shouto Todoroki, a powerful combatant, during their battle.

Keen Intellect: Katsuki has proven to be very smart and strategic, as he was able to figure out Kurogiri's Quirk weakness and Fumikage's weakness in a short period of time. Additionally, he quickly assessed which of the attacking villains in USJ was the most dangerous threat in the long term. Even Pro Heroes (such as All Might) have mentioned several times his great potential and battle-sense. Shouta Aizawa stated that in battle Katsuki shines his brightest.

Equipment and Weapons

 * "Grenadier Bracers": An adjustment added to Katsuki's hero costume that stores his nitroglycerin-like sweat. Once filled he can pull the grenade pin in order to release a large blast. As shown when he fought Izuku in All Might's Heroes vs. Villains test. It has enough explosive power to destroy all parts of the building within its blast radius. This equipment was first used during the Battle Trial arc in Chapter 9.
