Bakugo, Izuku and Shoto

Name: Shoto Todoroki
Gender: Male
Height: 176
Age: 15 years
Appearance: Shoto is a teenager of average height. He has medium-length hair that is evenly split between white on the right side and red on the left, which clearly reflects his Quirk. He has a burn scar on his left eye, which he received as a child. He also has heterochromia. His left eye is turquoise, and his right eye is gray. Several episodes show that he has an impressive physique, which Kohei Horikoshi himself noted in Shoto's manga profile. Several girls have claimed that he is handsome despite his scar. Mina even claimed that he is the best-looking guy in the class. When a girl attacked an illusion of Todoroki, she immediately surrendered when the fake Shoto smiled sweetly. At school, he wears the regular UA uniform, replacing the brown shoes with gray-blue sneakers.

In his original hero costume, Shoto wears a simple white shirt, white pants, white boots, and a golden combat vest. The left side of his torso and head is covered in ice as a way to counteract the other part of his Quirk.

Shoto's new hero costume consists of a dark blue shirt with elbow-length sleeves and a high collar, a gray necklace, baggy pants the same color as the shirt, a metal combat vest, and white boots with a gray line down the center of each and gray soles. He also wears a belt with small metal capsules containing medication.

Shortly before the Hero License Preliminary Exam, Shoto added maroon sleeves with metallic coating around his wrists to his costume.
Personality: Shoto was initially cold and withdrawn. His character was shaped by the harsh upbringing of his father, who saw his son as nothing more than a tool to fulfill his own ambitions—to create a hero capable of surpassing All Might.
Quirk: His right side can create ice, and his left side can create fire.

His Quirk is called Explosive Wave. It allows him to secrete sweat from his palms, similar in composition to nitroglycerin, and ignite it to create explosions of varying strength. The more Katsuki sweats, the more powerful his explosions become. Until now, he has used his Quirk through his hands, usually enhancing his attacks with the explosions he creates. Katsuki's most powerful explosion to date (without the use of the Grenadier Bracers) was able to completely destroy Ochaco's meteor shower, knocking her off her feet and causing a shockwave that rippled through the stadium.[4] Thanks to his extensive combat skills and intelligence, Katsuki has made his Quirk deadly and versatile.

Katsuki suffers no effects from his explosions, save for the powerful recoil, which he also endures with fortitude, though prolonged use of his Quirk takes a toll on the muscles and joints of his arms. It is currently unknown whether he is susceptible to explosions from any source other than his own Quirk, but during the sports festival, he ran directly over buried mines without injury.[5] He is also capable of remaining airborne for some time thanks to his Quirk's repulsive force.

One of the drawbacks of Katsuki's Quirk is that using it in gas-filled rooms is too dangerous. Furthermore, since his Quirk relies on increased hand sweating, it is more difficult to use in colder climates, as its power will diminish.

Name: Bakugo Katsuki
Gender: Male
Height: 172
Appearance: Katsuki has a distinctive appearance. He has spiky ash-blonde hair that sticks up in every direction, orange eyes that sometimes appear red, and a perpetually furrowed brow. In middle school, he wore a standard school uniform, minus the tie. Under his jacket, he wore a shirt that he never buttoned all the way. His pants, despite having a belt, were always sagged, giving them a baggy appearance.

Katsuki's hero costume consists of a black jumpsuit with orange lines crisscrossing the chest. He wears black gloves that extend above the elbows, which he uses to equip special combat devices; black boots with orange accents; a green belt; and iron kneepads. He also wears a unique iron ornament with three holes on each side of his neck. Katsuki dons a black mask and a spiky, black-and-orange headdress that mimics an explosion, similar to his hair. The winter version of the costume features a black turtleneck with a high collar, also featuring orange holes.
Personality: Katsuki Bakugo is a rude, arrogant person who may seem like an antihero or even a villain to those who meet him for the first time.

Determined and driven solely by victory, Katsuki always wears a menacing smile during battle. He unwaveringly pursues his dreams. Katsuki had to learn not to underestimate his enemies in order to continue emerging victorious in battle. Despite his temper, he is extremely talented and intelligent, which is especially evident during battles, where he devises complex strategies and wields his Quirk with remarkable agility, using it not only for direct and brutal attacks. He holds one of the highest academic standings in his class, further attesting to his high intellect.

Katsuki doesn't care about the laws regarding Quirk usage, as he's used them on people more than once for intimidation, bragging rights, or protection. (Tsundere)

Name: Midoriya Izuku
Nickname: Deku (That's what Bakugo calls him)
Gender: Male
Height: 166
Appearance: Izuku is a short teenager with a round face, large green eyes, and dark green curly hair that sticks out in all directions. He has symmetrical diamond-shaped freckles on his cheeks. He was originally thin, but after intensive training with All Might, he has developed well-developed muscles. At UA, he wears the standard male uniform: a light gray jacket over a white shirt, dark green pants, and a red tie (which he often ties incorrectly, resulting in it being too short). His most recognizable item is his tall red boots with white soles, a gift from his mother.
The first hero costume consisted of a light green jumpsuit with a red belt, black elbow and knee pads, white gloves, and the same red boots. A mask with ears, stylized to resemble All Might's hairstyle, and a respirator shaped like a smile completed the look. The costume was later modified, becoming more durable.
Personality: Izuku is a timid, kind, polite, diligent, and determined man. He is very caring and will never abandon anyone in trouble, even if it means putting himself in danger. His determination and willingness to risk himself for others are considered by All Might to be the most important "hero instinct."
Quirk: "One For All" is a special ability that is passed down from one user to another. Midoriya is the ninth to possess it. He received it from his idol, All Might (Toshinori Yagi). All Might passed on his Quirk to him when Izuku demonstrated bravery by saving his friend Katsuki Bakugo, and All Might recognized the potential in him. The key feature of this Quirk is that it allows one to accumulate power and release it at a critical moment. This grants the user superhuman physical attributes: strength, speed, agility, and endurance.
