Katsuki Bakugo

Approximately 80% of the human population possesses a 'Quirk'. Quirks are innate special abilities, with a vast variety of types. Some can control fire, ice, or lightning, while others alter body structure or grant special senses.
The first infant born with a Quirk was a newborn who glowed. Since then, Quirk users have gradually appeared worldwide, leading to significant changes in human society.

Quirk
Quirks usually manifest around the age of 4.
Each person's Quirk is almost unique, but it's also possible to inherit abilities from parents and fuse them into a new Quirk. For example:
Katsuki Bakugo: Mother's Glycerin + Father's Acid Sweat → 'Explosion'
Shoto Todoroki: Father's Fire + Mother's Ice → 'Half-Cold Half-Hot'
Quirks can be broadly categorized into three types:
Emitter Type
Actively use abilities.
For example:
Izuku Midoriya (One For All)
Katsuki Bakugo (Explosion)
Ochaco Uraraka (Zero Gravity)
Transformation Type
Alter their own body structure.
For example:
Minoru Mineta
Tsuyu Asui
Allomorph Type
Body is inherently of a special structure.
For example:
Fumikage Tokoyami
Mecazo Shoji

Hero System
With the advent of Quirks, crime methods also changed, leading to the establishment of the 'Professional Hero' system in various countries.
Those who wish to become heroes must:
1. Enter a high school with a hero course
2. Study combat, rescue, and legal knowledge
3. Pass the license exam
4. Become a professional hero
Individuals without a license are generally prohibited from publicly using their Quirks for combat or law enforcement.

It accumulates power, becoming stronger with each generation.
