10 Toshinori "All Might" Yagi (Unknown)

Anime My Hero Academia All Might Punch

Most famously known by his hero name "All Might," Toshinori Yagi is the top hero and Deku's number one idol. He's well-loved and has many years of Pro Hero experience to complement his overwhelming abilities. Unlike the other characters in My Hero Academia, Toshinori is the only character whose age is never fully revealed. However, fans know his birthday falls on June 10th.

Manga fans have decided to calculate Toshinori's age based on some of his life's milestones; they also based their findings on other characters' ages. One theory places All Might at 49 years old for most of the series, while another Twitter theory guesses he might be in his sixties.

9 Enji "Endeavor" Todoroki (45+ Years-Old)

Anime My Hero Academia Endeavor Stern

Shoto Todoroki's father, Enji, makes his first appearance as an angry 45-year-old. He's determined to outshine All Might and take the title of Best Hero. Enji's birthday is August 8th in the dead of summer, which perfectly fits his fiery powers and personality.

Unfortunately, Enji doesn't have the best track record. He hasn't been the best father to his youngest son Shoto, constantly forcing his ambitions upon him. Enji's lack of empathy created a rift between him and Shoto which will take a long time to mend.

8 Shota "Eraser Head" Aizawa (30+ Years-Old)

Anime My Hero Academia Aizawa Erasure Quirk

Also known as "Eraser Head," Shota Aizawa is a Pro Hero and Class 1-A's homeroom teacher. His age is difficult to determine because he looks older and more tired than his peers. Shota's actually 30 years old when he first debuts despite his haggard appearance. His birthday is on November 8th.

Shota's a tactical leader and strict teacher who tends to push his students to the limit. He's notorious for "failing" anyone he deems unworthy for U.A. — but it's actually a facade to encourage his students to rise to the occasion.

7 Tomura Shigaraki (20+ Years-Old)

As the League of Villains' leader, Tomura Shigaraki serves as one of U.A.'s main enemies. He has a severe hatred of heroes and wishes to completely eliminate them, especially All Might.

Tomura acts more childishly than his adult colleagues, but, like Shota, he looks older due to his corpse-like appearance. He's actually 20 years old, and his birthday falls on April 4th.

6 Himiko Toga (16+ Years-Old)

Himiko Toga From My Hero Academia

Like Tomura, Himiko Toga works for the League of Villains and is another primary antagonist. She's just a year older than Class 1-A, making her 16 years old. Himiko is cheerful and upbeat to the most uncomfortable extremes — especially compared to her brooding colleague.

Himiko is always seen in a school uniform, even in combat. She would be a second-year, considering she's a year older than Class 1-A, but it's not confirmed she attends school. Her birthday falls on August 7th.

5 Keigo "Hawks" Takami (22+ Years-Old)

Anime My Hero Academia Hawks Contemplates

Keigo Takami — also known by his hero name "Hawks" — is the third-best hero, now moved to second after All Might's retirement. Even though he's a Pro Hero, Keigo is about half his predecessors' ages.

For a 22-year-old, Keigo is both intelligent and powerful. His laid back and seemingly disinterested demeanor always throws people off when they meet him. But he always comes through when the time is right. His birthday falls on December 28th.

4 Mirio "Lemillion" Togata (18+ Years-Old)

Mirio Togata is an 18-year-old senior at U.A. and his hero name is Lemillion. His large build makes him appear older than other teenagers. On the other hand, his classmate Tamaki looks much younger despite being the same age.

Along with Tamaki and another classmate Nejire, Miro is part of U.A's "Big Three." The trio is considered the best of all of U.A.'s student body and have the most potential to become Pro Heroes. Mirio also shares a birthday with Deku: July 15th.

3 Katsuki Bakugo (15+ Years-Old)

My Hero Academia Bakugo Explosion Quirk

Katsuki Bakugo is one of My Hero's main characters and a first-year at U.A. High School. Like his classmates, Katsuki is 15 years old, and his birthday falls on April 20th. He's introduced as Deku's childhood friend, but he's more like a bully. Throughout childhood and middle school, he constantly teased Deku for not having a quirk, claiming Deku would never be a Pro Hero.

Despite wanting to be a Pro Hero, Katsuki is aggressive, harsh, and hot-tempered. He has the intelligence and fighting abilities to back up his confidence, but he refuses to work with others. He doesn't hold any of his classmates in high regard and has too much pride to ask for help.

2 Ochaco "Uravity" Uraraka (15+ Years-Old)

My Hero Academia's Uraraka training at U.A. High

Ochaco Uraraka, known as "Uravity," is one of Class 1-A's newest students and My Hero Academia's main protagonists. She's 15 years old when the series starts, and she may be the youngest in her class; her birthday falls on December 27th.

Since their first encounter, Ochaco has been Deku's biggest ally. She was the first person to talk to Deku during the entrance exams, and she helped him come up with his hero name. It has yet to be confirmed, but Deku may have a crush on Ochaco since he's always flustered whenever he talks to her.

1 Izuku "Deku" Midoriya (15+ Years-Old)

Deku in the forest

Izuku "Deku" Midoriya was 14 years old when he was first introduced. He spent some time training under All Might after inheriting his Quirk. Deku is shown again entering U.A. High School, making him 15 years old. His birthday is the same day as Mirio Togata's: July 15th.

My Hero Academia is told from Deku's perspective, as he studies to become one of the best heroes in U.A.. He greatly admires heroes and wishes to become one, even though he debuted without a Quirk of his own. Fans are excited to see how Deku evolves throughout the anime, learning to wield the new Quirk bestowed upon him.
