The shonen category is responsible for some of the most popular anime series, but My Hero Academia has made an especially big impact. The series is set to get into its fifth season and this brilliant blend of superhero and action tropes has turned into one of the must-watch anime titles from the past few years.

Part of the joy in My Hero Academia is how all of the young characters are able to mature and grow, but All Might is a character who enters the series as the established leader and symbol of peace. More details about All Might have come out over time and it’s been very interesting to get a better idea of this superhero’s full scope.

11 He’s 49 Years Old

My Hero Academia remains very focused on the next generation of heroes like Izuku Midoriya and the other students that freshly enter U.A. High. At the same time, the series doesn't completely disregard the older crop of talent and All Might is someone who still holds a lot of power. It turns out that All Might is actually 49 years old, which is actually revealed through Endeavor's age being 46, which comes to light during the Provisional License Exam. All Might is three years his senior, which provides the answer.

10 He Has A Scar On The Left Side Of His Chest

All Might is established to be one of the most powerful heroes in the series and this is even truer during his glory days before the anime begins. All Might is largely impervious to damage, but right from the first episode, he shows Izuku a massive scar that he has on his chest. This scar is a painful reminder of All Might's mortality. Even though Izuku speculates that Toxic Chainsaw is responsible for the wound and others have deduced it was All For One, it's still one of All Might's mysteries.

9 He Lowered Japan's Crime Rate By 3%

My Hero Academia is a series that’s all about how anyone has the capacity to become a superhero, but it still places a lot of emphasis on ranking and status as it wants its characters to know exactly how everyone stacks up against with one another.

All Might used to occupy the Number 1 Hero spot and he perfectly embodied the image of the Symbol of Peace. In fact, All Might’s work was so substantial and he instilled such positivity in the population that the crime rate of villains in all of Japan decreased by 3% thanks to his work.

8 He Was Initially Going To Be Much Older

It’s always fascinating to learn production secrets about how the story and character details can radically change over the course of a project’s development. Sometimes these shifts can even save a series from being a disaster. Initially, All Might was designed as a significantly older character who wasn’t supposed to be that important to the series. He would be a veteran hero that encourages Izuku to receive the call of action, but he wouldn’t be a frequent mentor for him. The editors weren’t impressed with All Might’s design and so they suggested that he have a younger and more severe appearance.

7 He's So Strong He Can Change the Weather

It’s easy to say that a character has super strength, but the range that this power can cover goes all over the place depending on the type of anime that’s being looked at. All Might is billed as one of the strongest heroes and even then this is when he’s not using 100% of his One For All Quirk. To properly demonstrate All Might’s power, a single punch from him contains the magnitude to make the weather shift. The same act can level several blocks of a city purely from the wind pressure that it creates.

6 He Can Only Use His Powers For An Hour

My Hero Academia has successfully introduced dozens of heroes with unique Quirks and it’s always impressive to see the sheer variety of superpowers that the anime explores rather than repeatedly rotating through the same few skills.

All Might’s One For All Quirk is a little basic in how it’s just immense strength, but due to its transference, All Might is left in a weakened state. He can only utilize his strong form for an hour each day. This ruse takes a lot out of All Might, but it’s even more stressful when he’s left with a small window of power.

5 He Has A Hero Agency In Tokyo

One of the more interesting components of My Hero Academia is to see how the series has slowly expanded its boundaries over time, both in terms of its characters and the worlds that they’re allowed to occupy. Later seasons get into the heroes’ efforts to get internships and find jobs as they meet characters like Sir Nighteye and get to apply their talents to the real world. All Might helps out in a lot of different areas, but he actually has his own hero agency that’s located in the Roppongi region of Minato, Tokyo.

4 All Might's Costume & Moves Are Modeled After The United States

My Hero Academia's All Might using United States Of Smash

All Might is such an entertaining character because at first glance he's largely a parody of superheroes like Superman and other American pop culture icons. All Might pushes this ideology as far as possible, right down to how the red, white, and blue colors of his costume are meant to be a representation of America and how it's an emblem of peace. However, even All Might's moves carry this branding. United States of Smash is his big finisher, but he also has techniques like Detroit Smash, Texas Smash, and even New Hampshire Smash as every detail about his reflects America.

3 His Ringtone Is His Catchphrase

My Hero Academia examines the full spectrum of what it means to be a superhero, which doesn’t just break down training and special powers, but even the more superfluous aspects of crimefighting. My Hero Academia dedicates time to heroes figuring out what their professional names should be and the intricacies of their costumes. Catchphrases are a less fundamental aspect of the work but something that’s still emphasized. All Might demonstrates just how thorough his branding is with how his catchphrase, “I am here!” is also what’s heard whenever his phone goes off. Even his e-mail notification echoes this mantra.

2 He's A Teacher At U.A. High

My Hero Academia’s scope has grown since the show’s debut, but U.A. High remains a grounding beacon for it. Midoriya and company may spend less time there, but it’s doubtful that this aspect will ever be dropped. There will always be characters that are connected to the institution in some way, whether as a student or a teacher. All Might himself actually teaches Foundational Hero Studies at the school, where he pulls from his vast experience and time in the limelight to analyze what it really means to be a hero and set the right example in these youth.

1 He Inherited His Quirk From Nana Shimura

Anime My Hero Academia Nana Shimura Smile

All Might's Quirk, One For All, is extremely powerful, but it's an ability that's all about looking towards the future and sharing this strength with a successor. My Hero Academia begins with Midoriya becoming All Might's selection to carry on the One For All legacy, but this naturally means that someone also had to gift All Might with the skill. All Might acquired One For All from Nana Shimura, his former mentor and a dear friend of Gran Torino. She unfortunately passed away but still was a crucial guiding force for All Might.
