Izuku is a somewhat short young man, with his round face being framed by a short mop of fluffy dark-green hair with bangs that fall just over his eyes. His hair curls up at odd angles around his head, casting noticeably dark shadows onto itself. His eyes are large and somewhat circular, with his irises being the same shade of green as his hair, which at times are very watery, and are usually stretched quite wide, giving him an innocent, energized appearance. He has a set of four symmetrical freckles in diamond formations, one on each cheek. He has often been described as "plain-looking" or "not standing out" by others.

Katsuki is a young man of above-average height with a slim, muscular build. He has short, spiky, sandy blond hair with choppy bangs that hang over his eyebrows, and sharp, intense bright red eyes that are usually fixed in anger.

Shoto is a moderately tall and rather muscular young man who is well-built for his age, stemming from his intense training as a child. He has short hair that doesn't pass his neck, with bangs that fall to his nose bridge, parted twice to avoid obscuring his vision. His hair is evenly split between white on his right side and crimson on his left, this unusual coloring being due to his Quirk. As another result, he also possesses heterochromia iridum, causing his quite thin and reserved eyes to have two differently colored irises; his left being turquoise, while his right is a dark gray. Additionally, he has a large burn scar on the left side of his face, which reaches from his hairline to halfway down his cheek. He usually has a serious expression, but despite this, several people in his class have claimed that he is quite handsome, as some classmates even goes as far as to say that he's the best-looking guy in Class 1-A.

Shota is a slender and tall, pale-skinned man with messy, shoulder-length black hair that partially hangs in front of his face and half-opened black eyes. He is usually recognized for his worn-out appearance, often looking fatigued. His facial hair is almost always in a stubbly, unkempt state (shaved for the press), and his eyes tired, bloodshot, and flat unless he's in combat.

Mina is a girl of medium height, set a little more broadly than some of her other female classmates, with, according to her profile, "healthy thighs". Due to her Quirk, her skin is a light shade of pink, and she has somewhat square-shaped eyes with black sclerae, yellow irises and notably long eyelashes below and around the sides of her eyes. Minoru Mineta once commented that "she's got a super athletic body".

Ochaco is a young teenage girl with a slender yet curvy figure, fair skin, and auburn hair with eyes that match in color. She has perpetual pink blush marks on her cheeks, and her eyes are large and round with thick upper lashes and pronounced lower lashes. Her hair is above shoulder-length with short, side swept bangs hanging above her eyebrows, and her hair is bobbed with two shoulder-length long locks of hair framing her face. She has small, pink, thick pads on her fingertips similar to the digits of an animal's paws; she uses these when activating and deactivating her Quirk.

Eijiro is a muscular young man of average height and a rather impressive physique for his young age. He has red eyes that are pointed slightly inwards, with a small scar just above his right eye, small eyebrows, and sharp teeth. His hair is somewhat long, dyed a bright red, and spiked away from his head at all angles with gel, with two more pronounced tufts spiked on either side of his forehead like little horns. This lofty style takes a full three minutes to set.

Tsuyu is a short girl of a relatively slender build and has notably large hands. Her appearance is rather frog-like; she has a wide mouth, which dips down a little in the middle just like a common frog, and oval-shaped eyes with large, black irises, with lower eyelashes being visibly pronounced. Between her family, Tsuyu's frog-like traits are the least pronounced. She also demonstrates some frog-like mannerisms, such as hopping on all fours instead of running and holding herself in a way that is somewhat connotative of a frog.

Denki is a light-skinned boy with messy golden-blond hair parted to the right with a black lightning-shaped streak on the left of his side fringe, which is angled to partially obscure his left eye. He has slanted, somewhat triangular golden eyes with small eyebrows, and is slimmer than most male students in his class, with little visible muscle mass.

Kyoka is a young, petite girl with a slender build. She has black, triangular eyes, with notably long lower eyelashes and small eyebrows. Her dark-purple hair is chin length, with an asymmetrical fringe that has two reflections shaped like sound waves on either side. She also has two chin length strands framing her face, and keeps the rest up to her neck. Her most prominent features are the flexible, plug-like earphone jacks hanging from each of her earlobes; they act like extra limbs that she is able to control at will, and change their length if so desired.
