Izuku Midoriya — the Quirkless boy who became the story

Izuku Midoriya, nicknamed "Deku," grows up in a world where roughly eighty percent of people are born with superpowers, and he is part of the powerless minority. What sets him apart before he ever gets a Quirk is obsessive, notebook-filling analysis of heroes — the kind of preparation that lets a nobody survive alongside prodigies. When All Might chooses him as the successor to One For All, a power that can be passed hand to hand, Midoriya inherits strength his own body can barely contain, and Season 1 is largely the painful process of learning not to shatter his own bones using it. He is the emotional engine of the show: earnest to a fault, reckless in defense of others, and defined by the belief that anyone can be a hero.

Katsuki Bakugou — the rival who refuses to lose

Katsuki Bakugou is the childhood friend who spent years belittling Midoriya, and his Explosion Quirk — sweat that ignites into blasts — makes him one of the most naturally gifted students at U.A. His snarling arrogance is real, but it sits on top of a genuine terror of being second-best, and the series treats his ego as a flaw to be worn down rather than a joke. Bakugou functions as the story's rival in the classic shonen mold: the measuring stick Midoriya chases and the person most disturbed by watching a former "Deku" suddenly rise. Loud, competitive, and weirdly principled, he is a lead in his own right, not just an obstacle.

Toshinori Yagi — All Might, the Symbol of Peace

Toshinori Yagi is better known as All Might, the number-one hero whose beaming smile is meant to reassure an entire society. Behind the muscular public form is a man running on borrowed time, weakened by an old injury he hides from the public, which is why the search for a successor drives the whole premise. His mentorship of Midoriya is the beating heart of the early series — part training, part fatherly guidance, part passing of a torch he can no longer carry forever. All Might gives the show its stakes: as long as he stands, evil is held back, and everyone senses how much rests on that.

Ochako Uraraka — the heroine with a fighter's pragmatism

Ochako Uraraka is the first classmate to treat Midoriya with plain kindness, and her cheerful warmth makes her easy to underestimate. Her Zero Gravity Quirk lets her make objects — or herself — float by touch, a support-heavy power she turns into surprisingly aggressive tactics. Crucially, she is not in hero school for glory: she wants a stable, well-paid career to lift her working-class family, which gives her a grounded motivation the flashier students lack. Uraraka rounds out the core trio with Midoriya and Iida and quietly becomes one of the class's most determined competitors.

Shouto Todoroki — half-cold, half-hot, all pressure

Shouto Todoroki enters as a prodigy who barely needs to try, admitted on recommendation and able to freeze a battlefield solid with the ice half of his Quirk. The other half — fire — he pointedly refuses to use at first, a choice tied to a complicated inheritance from a famous hero father. Season 1 mostly establishes him as the cool, distant ace who out-classes his peers, with the emotional reckoning saved for later arcs. Even in these early episodes, though, he reads as the rival with the deepest well of unspoken history, and his gradual thaw becomes one of the franchise's defining arcs.

Tenya Iida — the class president who learns restraint

Tenya Iida is the rigid, rule-quoting honor student with engines built into his calves, letting him rocket around the battlefield at high speed. He comes from a distinguished hero family and takes the responsibility almost too seriously, chopping the air with earnest gestures as he lectures his classmates on procedure. Beneath the stiffness is real loyalty, and the series enjoys puncturing his formality to reveal a genuinely warm friend to Midoriya and Uraraka. As Class 1-A's representative, he is the group's conscience — the one who insists on doing things the right way, even when the right way is hard.

Shouta Aizawa — Eraser Head, the teacher who cancels powers

Shouta Aizawa, the pro hero Eraser Head, is Class 1-A's exhausted, cynical homeroom teacher, and he opens his tenure by warning that whoever finishes last in a brutal Quirk assessment will be expelled on the spot. His Quirk erases other people's powers just by looking at them, making him a nightmare for flashy opponents and a nerve-wracking proctor for students. The deadpan exterior hides a teacher who genuinely believes his brutal standards keep kids alive in a dangerous profession. When real villains attack, Aizawa is the frontline pro who proves the difference between a licensed hero and a talented teenager.

Tomura Shigaraki — the hand that wants it all to fall

Tomura Shigaraki is the unsettling young villain who leads the League of Villains onto the stage in Season 1, his body draped in severed hands and his Quirk able to decay anything he grips with all five fingers. Where All Might symbolizes stability, Shigaraki embodies the itch to tear that stability down, and his childish petulance makes him more disturbing rather than less. His introduction reframes the whole series — the heroes are not just training, they are being hunted. The deeper truth of who he is stays a mystery in these early episodes, but the threat lands immediately.

The rest of Class 1-A — the classmates who round out the roster

Beyond the leads, U.A.'s hero course is stacked with distinct personalities. Tsuyu Asui — "Tsu" — is the frog-Quirk hero and the most reliably level-headed voice in a crisis. Eijirou Kirishima can harden his body like stone and lives by a loud code of manliness that makes him the group's dependable backbone. Momo Yaoyorozu creates objects from her own skin and is the class's sharpest strategist, while Fumikage Tokoyami fights alongside the shadow beast Dark Shadow with a brooding cool all his own. Rounding out the fan favorites, Kyouka Jirou weaponizes her own heartbeat through earphone-jack earlobes, Denki Kaminari blasts electricity until his own brain short-circuits, and Mina Ashido melts obstacles with acid while keeping the class's social energy high.

Frequently Asked Questions

Who is the main character of My Hero Academia?

The main character is Izuku Midoriya, often called Deku. Born without a Quirk in a world of superpowers, he is scouted by the top hero All Might and inherits the transferable power One For All, then enrols at U.A. High to train as a hero. The series follows his growth from powerless dreamer to a student who can actually stand beside prodigies.

Who is the strongest character in My Hero Academia?

In the era of Season 1, the strongest hero is unquestionably All Might, the Symbol of Peace, whose raw power dwarfs everyone around him. Among the students, Katsuki Bakugou and Shouto Todoroki are the standout talents, while Midoriya's ceiling is the highest of all thanks to One For All — he just cannot use it safely yet. On the villain side, Tomura Shigaraki is positioned as the long-term threat.

How many main characters does My Hero Academia have?

There is one clear protagonist, Midoriya, supported by a tight inner circle of leads — All Might, Bakugou, Uraraka, and Iida — plus the ace rival Todoroki. Zoom out and Class 1-A holds twenty students, most of whom get moments to shine across the series, so the "main cast" you actually need to know sits at roughly eight to ten names.

What are Quirks in My Hero Academia?

Quirks are innate superpowers that around eighty percent of the population is born with, ranging from Bakugou's explosions to Uraraka's zero-gravity touch to Todoroki's ice and fire. Each person typically has one Quirk, which is why Midoriya being born Quirkless is such a big deal — and why the transferable One For All he receives is so unusual.

Why is Izuku Midoriya called Deku?

"Deku" starts as an insult from Bakugou, a play on Midoriya's name that also reads like a word for "useless." Uraraka later reframes it, saying it sounds like "dekiru" — "you can do it" — so Midoriya adopts it as his hero name. The nickname's journey from taunt to badge of pride mirrors his entire arc.

Is All Might related to Deku?

No. All Might, whose real name is Toshinori Yagi, is Midoriya's mentor, not his father or relative. Their bond runs deep because All Might passes his power and his ideals to Midoriya, making the relationship feel like a father-and-son handoff — but they are not blood family.
