Monoma and Bakugo

Appearance: Short, spiky sandy-blond hair, sharp, bright red eyes. The hero's outfit consists of a black sleeveless top and pants with grenade-shaped gloves, reflecting his explosive Quirk.
Biography
As a child, Katsuki bullied his best friend, Izuku Midoriya, for not having a Quirk.
After entering UA Academy, Katsuki's character began to change: he began to look at his life differently, although his rudeness and arrogance remained.
One of the key events was Katsuki's kidnapping by the League of Villains, which became a turning point: he was confronted with his own weaknesses and the reality of the hero world.
Capabilities
Katsuki's Quirk is "Explosion." The sweat on his palms acts like nitroglycerin, and Katsuki can use it to create explosions.

Some techniques in combat:
Explosive Turbo Dash - Katsuki pulls his arms back and then uses explosive power to propel himself some distance away.
Flashbang Grenade - By activating his Quirk between his two palms, Katsuki creates a low-power explosion that can temporarily blind opponents.
Howitzer Charge - Katsuki leaps into the air and creates two powerful explosions, building up his attack power by spinning around himself, before delivering a devastating blow to the enemy.

Personality
A rude, arrogant man who may seem like an antihero or even a villain to those who see him for the first time.
Determined and thirsty for victory, he always smiles menacingly during battle.
He is talented and intelligent, which is especially noticeable during battles, where he comes up with complex strategies.
Due to constant praise for his abilities, Katsuki developed a superiority complex, he wants to be first and the best in everything

Appearance
Itsuka is a pretty girl with large green eyes and long red hair tied in a side ponytail.

Her hero costume consists of a light blue knee-length qipao dress, a black corset, and black athletic shorts. She also wears black boots, a brown belt, and a black cloth mask.

Personality
Itsuka is a cheerful and energetic girl. She doesn't hesitate to criticize her classmates if she feels they're doing something wrong or bad. For example, she scolds and chides Monoma when he provokes the students from 1-A. She's willing to give in to others if she believes they deserve it, as shown when she allowed Shiozaki and Tetsutetsu to take the spots offered to her team during the sports festival.

She treats everyone equally friendly and harbors no ill will toward Class A. She sympathized with Midoriya and Iida when she heard about their encounter with Stain and, without a hint of reluctance, told them what was expected to be the practical portion of the final test.

She's quite intelligent, and therefore relies primarily on her wits in combat. She easily determined that the clouds of poisonous gas that appeared in the forest during the trip to the training camp were caused by someone's Quirk, and used this insight to find the villain who created them, and selflessly used her Quirk to dispel them.

Appearance
Neito has short, sleek blonde hair that parts to the right of his forehead.

His hero costume is a dark tailcoat and a light-colored short-collared shirt with a tie. He wears several watches around his waist, presumably to help him keep track of how long he's been using his Quirk.

Personality
Neito is calm, collected, and intelligent. He wants to eliminate Class 1-A's popularity. However, he is unpleasant, sarcastic, and loud. Neito is a bit jealous of Class A's popularity.

He seems to have an inferiority complex, as he uses every opportunity to bully or challenge the students of Class 1-A. In the School Camp Arc, he was the only student from Class 1-B to fail the Annual Test. Many consider him mentally unstable, but this is most likely a joke.

Despite his self-confidence, he seems to feel threatened by Class A. For example, when he received his Provisional License, he breathed a sigh of relief upon learning he wouldn't have to deal with Class A.
