My Hero Academia is set in the idea that more than 80% of the world's humans have "personalities." However, in a world where most people have personalities, there are 4 characters who are born without personalities, three of them inherit of offa (one for all), and the other chooses to become a scientist.
Olmet
Olmet is recognized as the No. 1 hero in the world and a symbol of peace, but few people know that Olmet is also a person born without personality. He inherited the offa because Shimura approved of him. After that, Olmet continued to grow stronger, and eventually became the world's number one hero, without the opponent he could not defeat, that is, afo (all for one) was also sent to prison by Uncle Ou himself, even if he escaped, he was defeated by Uncle Ou again.
However, Olmet has passed on the ofa to Midoriya Iku, and now he is back in the background and specially cultivated for a long time. Olmet is a symbol of the times, because of his existence, the crime rate in Japan is controlled below 6%, but unfortunately, when fighting with AFO, the physical damage is too large, and when there is no inheritance to give a long Afo, it can only maintain a strong form for about 2 hours. As for him now, he can hardly change.
Midoriya out of the long
The ninth generation of ofa inheritors is also a naturally impersonal figure. When he was detected to have no personality, he was once depressed, and later because of his instinct to save Hao, he was recognized by Olmet. Olmet passed on the OFA to him and trained him for ten months before he was able to use the OFA. Today, Green Valley already has its own combat suits and its own heroic name, and has shown outstanding combat talent in many battles.
Midoritani will one day become the strongest hero like Uncle Ou. Usually, he likes to talk to himself and collect information, but these can be transformed into important experiences in combat, and he is still growing, and may one day surpass Ormet.
AFO's younger brother
Afo (all for one) has a younger brother who is born without personality (no name known), and ofa is what afo gave him. Afo's younger brother is the owner of the original ofofa, but also a figure with a sense of justice, once rebelled against afo, but finally failed, after the failure of the offa passed down from generation to generation, to Uncle Ou is the eighth generation, Iku is the ninth generation.
Melissa
A character in the theatrical version of My Hero Academia: Two Heroes, she is also the daughter of David, a close friend of Ormet. At the age of 5, Melissa was detected to be born without personality and had a period of lows like Iku, but eventually came out, following the example of her father, David, who is now a brilliant scientist. Although they all sit behind the scenes and make all kinds of hero equipment, this is also her hero path. Melissa is a girl with a very good personality, who has fought with Iku and made him an all-round handguard.
These 4 characters, who are born without personality, are all very good characters, especially Melissa, and in the end there is no personality inheritance. Uncle Ou, Ikuhisa and Afo's younger brothers all inherited offa and became stronger from generation to generation.
