The Hero Association (ヒーロー協会, Hīrō Kyōkai), also known as the Superhero Society, is an organization founded by the multi-millionaire Agoni that manages all of the cities' superheroes. Agoni has also established the National Superhero Registry, the database that embraces every recognized superhero. The Association uses a class system, with 4 classes and ranks within those classes (Classes A, B, C and S), to organize every superhero accordingly. They are now opposed by the Neo Heroes.
Three years before the current storyline, the Hero Association was founded by multi-millionaire Agoni, whose grandchild was attacked by a mysterious being and saved by Saitama (with hair). After hearing what happened, Agoni came up with the idea and founded the Hero Association and the National Superhero Registry from private funds.
After Garou's incident, the organization is under threat of replacement by the Neo Heroes. Furthermore, they also get into a lot of corruption scandals in regard to illegal activities of donors, employees (example: Guichess case) as well as the fact that they quiet neglect in controlling their S-class heroes especially Tatsumaki in term of collaborating damages during their heroes activities. Furthermore, the rising in losing battles of heroes against Mysterious Being causing the public to lose their faith in the competency of the organization as well as some people now aware of the dark and negative sides in term of some of the more arrogant, inept and violent heroes now begin to pose a bigger threat to the organization.
National Superhero Registry
The National Superhero Registry is a database that contains the names of every officially recognized superhero. Any person not registered in the National Superhero Registry is not recognized as a hero and, as such, is always looked upon as a delusional weirdo, regardless of how many times they saved the world.
Super Hero Entrance Exam
To become an official Hero of the Hero Association, a candidate must pass an entrance exam. The entrance exam consists of two parts:
1. Fitness Test - The fitness portion of the test tests agility and physical strength. The known components of this portion of the exam included: side-to-side jumps (for 30 seconds), a 1500 meter run, weight-lifting, and squat jumps. The anime version of the fitness portion adds shot put, whack-a-mole, and punching machine components.
2. Written Test - The actual content of the written test is currently unknown, but Genos referred to both the Fitness and Written Tests as a, "...walk in the park." Genos also said of the written test that it, "is too easy to be called a test..." The written test is designed to assess the candidate's "sense of justice"; one staff member of the Association mentioned that it had an essay section.
Passing the Entrance Exam has the following actions:
- A hero is officially recognized by the Hero's Association.
- A hero is entitled to the Association's money made from donations in proportion to the tasks completed.
- An "ability" rank will be assigned based on the results of the exam (see "Classes" section, below).
- A hero will be eligible to be voted upon by the public in the hero popularity ranking.
There are four classes for Heroes, with C-Class being the weakest and S-Class being the strongest:
- S-Class, with a total of 17 heroes
- A-Class, with a total of 38 heroes
- B-Class, with a total of 101 heroes
- C-Class, with a total of 390 heroes
Thus there are a total of 546 heroes. To go to the next class up, a hero must be ranked #1 in their class, at which point they can choose to stay at the top of their class or start at the bottom of the next class, or, such as with Genos, a hero can be put directly into a higher class if their score on the registry test is high enough.
