Debut: Chapter 164 (Manga)
A newbie teacher at Masegaki Elementary School.
- All There in the Manual: Her name was only revealed in the Volume 18 extras.

- Badly Battered Babysitter: She can barely keep up with her students, never mind Bakugo and the others.
- Meaningful Name: "Komari" means "to be troubled/vexed".
- Shrinking Violet: Horikoshi describes her as having a timid personality.
Debut: Chapter 164 (Manga)
Student's Quirks: Tongue Tank, Binging Ball, Queen Beam, Assault Dust
A class of mischievous elementary school students that Bakugo, Todoroki, Yoarashi, and Camie need to win over for their license exam retaking lessons.
- Adorably Precocious Child: Some of them are very socially aware for their age, but it's mostly Played for Laughs.
- Bratty Half-Pint: They're all very hyperactive and mischievous.
- A Child Shall Lead Them: Subverted. There is one sharp-dressed boy who is decidedly not pure of heart and acting as the class's ringleader, smugly coaxing on the rest of the kids and lashing out because he hates how adults are so sure of themselves that they know best and quick to dismiss children like him from having the freedom to be in charge of anything, making all the decisions for them. He is easily frightened into backing down when Bakugo confronts him and has him about ready to wet himself in fear.
- Children Are Innocent: Subverted. The high schoolers are ready to approach them as innocent children, but the boys are all insufferably cocky and scrappy while the girls are already aware of seduction and sex appeal.
- Dirty Coward: The "boss" of the class hangs back and arrogantly leans against a wall acting all confident and mocking the remedial students when the teens can't get through to the group, but he is easily cowed when he's cornered by Bakugo, evidently hiding behind the other kids he convinced to run wild.
- Kids Are Cruel: The girls slut-shame Camie for taking the boys' attention off them, while the boys are happy to make fun of the hero students assigned to take care of them and attack them with their Quirks.
- Meaningful Name: "Masegaki" can be translated as "precocious brat."
- Troubling Unchildlike Behavior: Some of the boys act like teenage rebels. The girls also partake in Slut-Shaming Camie. They're also much better at using their Quirks than Aizawa's generation and have much wilder mutations, which leads into some slightly disturbing theories on what is referred to in series as the "Singularity".
- Unusual Weapon Mounting: One of the kids is capable of turning themselves into a cannon, with the muzzle coming from his mouth.

Debut: Chapter 57 (Manga), Episode 31 (Anime)

- All There in the Manual: He is given a name and a brief backstory in Volume 7.
- Base-Breaking Character: In-universe, he became this after cutting one of his horns off for the sake of his job, as his horns obstructed camera views. While there is a group of viewers that praise him for putting his job over his Quirk, there is another group that derides him for seemingly denying his own Quirk, thus "promoting Quirk discrimination".
- Horned Humanoid: Thanks to his Quirk.
- Villain Respect: Twice of all people (or at least one of his personalities) respects his journalistic integrity.

Debut: Chapter 70 (Manga), Episode 40 (Anime)
Quirk: Unnamed Water Quirk
Mandalay's young nephew. His parents were heroes who were killed in the line of duty. He possesses a Quirk like theirs that lets him generate water.
- The Bus Came Back: Along with the Pussycats, he visits Class 1-A at their dorm in Chapter 184 after about ninety chapters of absence.
- Cool Hat: His hat has two spikes sticking out.
- Freudian Excuse: Hates heroism because it cost his parents their lives, and everybody around him would go on about how it was an honorable way for them to die.
- Groin Attack: When Midoriya attempts to introduce himself, Kota responds by punching him straight in the family jewels. He later apologizes for it in his letter to Midoriya.
- Hero-Worshipper: Though he's loathed to admit it, he becomes Midoriya's first fan after being saved by him from Muscular. The next time they meet after the training camp incident, Kota has picked out red sneakers to be just like his idol.
- Irrational Hatred: He utterly despises all heroes and Quirks because his parents were heroes and they got killed when they were murdered on duty by a villain. However, this is justified because he's a young child who doesn't really understand why everyone praised his parents' honorable deaths.
- Making a Splash: As both of his parents had water-based Quirks, he gets this by default.
- Meaningful Name: His given name contains the character for "sparkling water", while his surname means "flood". Fitting for someone with water powers.
- Must Make Amends: He sends a letter to Midoriya, thanking him for saving him and apologizing for his Groin Attack. He also asks him to heal soon so he can apologize properly.
- Nice Shoes: He asked Mandalay to buy him a pair of red shoes just like Midoriya's, which she eagerly points out when the Pussycats stop by the U.A. dorms and check their street shoes at the entrance for indoor slippers, drawing attention to his new red shoes sitting by her dress heels. Kota is instantly embarrassed for being outed for his secret hero worship of Midoriya.
- Strong Family Resemblance: Flashbacks show that he strongly resembles his father, having inherited spiky black hair and similar face and eye shapes.
- Tears of Fear: The second he lays eyes on Muscular for the first time after the villain sheds his cloak and mask to fight, Kota realizes this is the monster who murdered his mom and dad and understandably falls apart. He's so distraught that all he can do is cry and scream in panic.
- Troubled Child: Very surly, and talks like someone much older than he actually is to cope with his grief.
- Tsundere: He tries to keep up his tough, surly facade in an effort to hide his fanboy tendencies towards Midoriya. He is flustered when Midoriya tells him he treasured the letter that Kota sent him while recovering in the hospital.
Debut: Chapter 186 (Manga)
An 18-year-old Endeavor fan who became the In-Universe meme "Can't ya see-kun".
- All There in the Manual: His name is only given in the volume 21 omakes.
- Creator Backlash: In-Universe. He's not exactly happy about his Rousing Speech becoming a meme, but he's proud that he's managed to improve Endeavor's public image.
- Hero-Worshipper: He obviously greatly admires Endeavor, but he also just likes heroes in general.
- Memetic Mutation: An In-Universe example. His Rousing Speech in support of Endeavor not only got other people to support Endeavor, but a recording of it also went viral and even lead to unofficial merchandise being made.
- Rousing Speech: Gives an impressive one during the Darkest Hour of Endeavor and High-End's battle. The crowd watching has lost all hope due to Endeavor's apparent defeat and begin wishing All Might was there to save them. Then Hiroshi's voice rings through the crowd, and he begs them to believe in their new #1 hero, because his flames are still burning and he's there to protect them. Cue Endeavor, half blind and running on pure adrenaline, rising from the ashes, using his flames to propel his battered body straight into High-End, with a crowd of people cheering for their heroes success.
- We Want Our Jerk Back: When he got a chance to meet his hero, it was around the same time that Endeavor decided to clean up his Jerkass image. Unfortunately, Hiroshi thought Endeavor was cool in-part because he was antagonistic and is put-off be the change in attitude. It doesn't deter him from being a fan, however.
Debut: Chapter 218 (Manga)
Quirk: Unspecified Animal Quirk
An employee working for the Detnerat Company who has a close relationship with the CEO.

Flashback Only Characters
Voiced by: Kenta Okuma (Japanese)
Debut: Chapter 1 (Manga), Episode 1 (Anime)
Quirk: Unnamed Demon Wing Quirk
A young boy with an unnamed Quirk letting him grow and fly with wings. He was friends with Bakugo as a child and helped him bully Midoriya for being Quirkless.
- All There in the Manual: He is the grandson of Dr. Tsubasa, the doctor who diagnosed a young Midoriya as Quirkless. This information is only found, along with his name, within the databook.
- Ambiguous Situation: While heavily implied by Kōhei Horikoshi in Volume 7 that Tsubasa is connected to the winged Nomu, it is not yet clear whether his Quirk was simply stolen by All For One to give to that Nomu, or if he was actually turned into that very Nomu himself.
- And I Must Scream: Implied. While possibly having been turned into a Nomu, as shown below under Fighting from the Inside, he likely retained a certain degree of his own memories and consciousness in this form. If so, his death by Stain was unintentionally a Mercy Kill.
- The Bully: As a child, he, along with their unnamed friend and Bakugo, often beat up and belittled Midoriya, just for being Quirkless.
- Eyes Always Shut: In both Midoriya and Bakugos flashbacks, he is shown looking like this.
- Fat Best Friend: Was this to his Childhood Friend Bakugo back in elementary school.
- Fighting from the Inside: Implied. In the Volume 7 omake, Horikoshi gives the "hint" of - "Why did the winged Nomu pick Midoriya out of the whole crowd specifically?" - providing only a sketch of Tsubasa. This question, combined with the actions of that Nomu grabbing Midoriya in its wounded state - heavily implies that not only might it have once been Tsubasa, but that it still retained some subconscious sense of self and memory of Midoriya at that point, possibly because of his connection to its past.
- Good Wings, Evil Wings: Downplayed. His wings manifest themselves as red and draconic, but he is not truly evil, just a mean-spirited bully.
- Growing Wings: How his Quirk seems to work. Episode 1 shows he can instantly manifest and presumably retract both pairs of wings at will.
- Meaningful Name: Tsubasa's name means wing or wings, which fits perfectly with the nature of his Quirk.
- What Happened to the Mouse?: This is lampshaded in the databook, which notes that - despite being in elementary school with Bakugo, their unnamed friend, and Midoriya - for some reason, he didnt end up going to the same middle school like the rest of them.
- Winged Humanoid: His Quirk gave him large wings.

Debut: Chapter 1 (Manga), Episode 1 (Anime)
A doctor who first diagnosed Midoriya as Quirkless when he was a child. His name is revealed in the databook.
- All There in the Manual: He is the grandfather of Tsubasa, the chubby winged kid who was childhood friends with both Midoriya and Bakugo. This information is only found, along with his name, within the databook.
- Badass Moustache: Sports a rather impressive mustache, as seen in his profile picture above, while also being completely bald.
- Bearer of Bad News: Informs Midoriya that he is Quirkless, which utterly devastates the latter.
- Brutal Honesty: His diagnosis of Midoriya being Quirkless is then followed by him telling the latter to basically give up any dreams of ever becoming a hero. Take note that Midoriya was just a four-year-old kid at the time.
- Inexplicably Identical Individuals: Bears a surprising resemblance to All For One's doctor, right to the mustache, style of glasses, and sharing a voice actor.
- Labcoat of Science and Medicine: Has this overall look as a doctor, complete with a stethoscope.
- Lennon Specs: Wears these kinds of glasses, which are dark green with brown frames.
- Mr. Exposition: Explains to Inko, and thus the audience, that her son's Quirkless status is due to having two joints in his small toe from birth, whereas Quirk users only have one joint in their small toes.
- Small Role, Big Impact: Only appears within two of Midoriya's flashbacks, but his diagnosis is responsible for changing Midoriya's life completely prior to him meeting All Might many years later.
Debut: Chapter 225 (Manga)
A former classmate of Himiko Toga in middle school, who was her first "love" and later victim.
- First Love: He's the first person that Toga fell in "love", and that ended up getting him horribly wounded.
- Identical Stranger: He bears a surprisingly strong resemblance to Izuku Midoriya, but is able to wear his necktie properly.
- Posthumous Character: Ambiguous. He was certainly Toga's first victim, but the new reporters only say she "attacked" him, and some of the interviewees talk about him like he's still alive.
The Luminescent Baby
Debut: Chapter 1 (Manga), Episode 1 (Anime)
Quirk: Unnamed Luminescent Quirk
Born Qing Qing City, China, the Luminescent Baby was the first person in the world to be born with a Quirk

- Light 'em Up: Their Quirk was a simple one; it made them lightly glow.
- Minor Major Character: They have no role in the present narrative, but since they were the first ever person to have a Quirk, they're an incredibly important part of My Hero Academia's world.
- Posthumous Character: They had the first Quirk, and Quirks have been around for at least five generations, so this is clearly the case.
The Mother of Quirks
Debut: Chapter 232 (Manga)
A historic woman. Her son was born with a Quirk during the era of chaos where prejudice against Metas (Quirk users) was at it's worse. She spoke out against this discrimination by claiming that his power was simply one of his "Quirks". Her words fell on death-ears at the time, but eventually, the government co-opted her words when they brought order back to the world via Quirk regulation. Her son, however, felt that the government had stolen her words without understanding what she truly wanted and rebelled against the regulations. He went on to found the Meta Liberation Army under the name "Destro" in order to defend his mother's wishes.
- Posthumous Character: She was killed by an Anti-Meta Mob for daring to speak out against Quirk discrimination.
