Bakugo Katsuki and Kirishima Eijirou.

Eijiro Kirishima (Red Riot)
Personality: Cheerful, honest, and extremely loyal. His code of honor is built on the concept of "manliness": he admires noble deeds and is willing to risk himself for others. He previously doubted his Quirk, considering it boring, but later gained confidence.
Appearance: A muscular man with sharp, shark-like teeth. He has red eyes and a small scar above his right eye. His hair is naturally black, but he dyes it bright red and styles it into ponytails in honor of his idol, the Scarlet Riot.
Height: 170 cm.
Cloth:
School Uniform: The standard gray UA jacket, which he wears neatly.
Hero Costume: Consists of dark red gear-shaped shoulder pads, black baggy pants with a torn hem (resembling a cape), and an open torso to facilitate the use of the Hardening Quirk. An "R" emblem is embossed on the belt.

Katsuki Bakugo (Great Explosion Murder God Dynamight)
Personality: Arrogant, aggressive, and hot-tempered. He possesses an incredible will to win and a talent for combat, but has long suffered from a superiority complex. Despite his rudeness, Bakugo is very intelligent (one of the best in his class academically) and has a strong sense of justice, though he expresses it in his own peculiar way.
Appearance: Bakugo has a slender but highly toned build. He has spiky ash-blonde hair and sharp, perpetually "angry" red eyes.
Height: 172 cm. In the future (after the timeskip), he becomes noticeably taller and more massive.
Cloth:
School uniform: Wears it casually - jacket open, white shirt unbuttoned to the top buttons, no tie, and pants hanging low.
Hero costume: Black tank top with an orange "X," massive grenade-like gloves on the hands to accumulate sweat (nitroglycerin), and a metal protective collar. He wears an explosion-shaped headdress.
