Prevalence: About 80% of the population has a quirk, the remaining 20% are "quirkless".
What is a quirk: a unique ability. Someone generates fire or ice, someone changes the body (for example, grows additional limbs), and someone influences others. There is no official classification, but according to mechanics they are conditionally divided into types: radiation (release energy / substances), impact (affect something upon contact), transformation (temporarily change the body) and mutation (ability is a permanent part of the body). Each has its own strengths and weaknesses.
How it works in society: A whole industry has emerged. The heroes are trained (the main one is the UA Academy), receive licenses, investigate crimes and protect citizens. In parallel, villains act - those who use abilities to harm. They form groups (for example, the League of Villains).
Special mechanisms: There are also unique cases. For example, the All-for-One quirk allows the owner to steal other people's abilities, accumulate them, and even transfer them to others. And scientist Kyudai Garaki has learned how to artificially create and combine quirky factors, which is how Nomu, genetically modified creatures with multiple abilities, appeared.
Conflicts: often the plot is based on confrontation. Heroes versus villains, as well as on internal issues — what it means to be a real hero, how society treats people with unusual abilities and those who do not have them.
