Agoni

We're entering an era when you and your loved ones can all live in peace and safety.

Agoni (アゴーニ, Agōni) is a multi-millionaire and the founder of the Hero Association. He came up with the idea when his grandson was attacked by a Mysterious Being 3 years prior to the events of One-Punch Man.

Appearance
Agoni is largely characterized by his enormous cleft chin. He is an older looking man with a wide nose, large mustache and heavy eyebrows. His hair is straight brown and parted on the left. He dresses in a formal business suit.

History
Agoni's grandson jokingly vandalized the shell of Crablante, a Mysterious Being, which made him the target of the being's slaughter. He was saved, however, by Saitama, a passerby stranger. Agoni was so moved by this that he created the Hero Association and the National Superhero Registry to create and manage superheroes like Saitama, who would protect humanity against the Mysterious Beings.
