MHA Shows People Born Without Quirks Can Be Heroes.
Generally, it is seen as impossible, though not actually prohibited, for Quirkless people to become Heroes due to their need to combat Villains and enter dangerous situations.
He can. He very much can become a hero even when Quirkless.
My Hero Academia is a world where 80% of the population possesses a superpower called a quirk. Over time, being a superhero became one of the most competitive jobs out there, and while most have power, few are strong enough to earn the title of hero.
It'd be slightly different from Endeavor or Todoroki because he could only create fire from his mouth, and he would have much better control over its movement. Also he would be able to manipulate external fire, like on a torch or stove.
Garaki specifically stole Deku's quirk from him as a child because of its impressive potential, it's also likely that same quirk could've been the ability that All For One chose to pass down to his quirkless successor, Shigaraki.
Izuku's quirk, One For All, can stockpile one's power, increasing the user's physical capabilities and being transferred from one person to another.
1 Shigaraki
All For One is arguably the rarest and most powerful Quirk possessed by any villain in My Hero Academia. This Quirk so thoroughly defines its bearer that he's taken it as his name. All For One's Quirk lets him steal Quirks from other people and use them as though they were his own.
One of the most rare quirks is any type of healing or medical related quirks. ONE character has it in the known MHA universe, which is the Recovery Girl. And the other is warp. Eri's quirk is proabably one of, if not THE most rare quirk in all of MHA.
All For One is, quite possibly, the strongest Quirk there is in My Hero Academia. It was formerly wielded by All For One and is currently in Shigaraki Tomura's possession.
It is then that Deku realizes that overuse of his new quirks will lead him to be temporarily paralyzed. Just like his journey to train his body to handle OFA, Deku learns that he must also slowly work to get his body accustomed to all the previous OFA users' quirks as well.
Deku's final quirk is known as 'gearshift'. It's a quirk that is activated via physical contact. It allows the user to change the velocity of anything they touch, meaning they can spontaneously slow things down, or speed things up.
No, it was explained in the manga that Monoma only copies the bare essentials of a quirk and One For All is only strong because of all the power it has stockpiled through various past One For All user and through so many generations so Monoma copying One For All wouldn't do anything for him.
Quirks came randomly. The series started with people spontaneously gaining quirks. So it follows that two quirkless parents could have a child with a quirk.
Quirks can also be used by civilians in public spaces for cases of self-defense—but only to help you dodge, escape, or shield yourself, not to actually strike back. So using your quirk to attack your attacker is illegal (with exceptions made in designated areas like the USJ).
10 The First Quirk
The first known Quirk is said to have been wielded by a baby in China's Qing Qing City. While the reason behind the sudden appearance of this Quirk is unknown, it is said that the baby wielding this Quirk glowed with a luminescent light, and was thus called the 'Luminescent Baby'.
Anime Debut
The Luminescent Baby (発光する赤児, Hakkō suru akago?) was the first person in the world born with a Quirk.
The protagonist of My Hero Academia, Izuku Midoriya was the first Quirkless character to be introduced. Izuku was born without a Quirk, but despite that, he wanted to become the Number One Hero, just like All Might.
Trivia. Life Force, All For One, One For All, Fa Jin, Gearshift, and the unnamed Luminescence Quirk are the oldest known Quirks in the series.
A quirk is a unique, odd, and sometimes charming trait that makes a person stand out from the crowd. Country comedian Minnie Pearl was known for her quirk of wearing a $1.98 price tag dangling from her hat. A quirk can be an adorable little habit, like wearing flowery dresses and big sun bonnets or bow ties every day.
After reading a few official theories about Deku having a quirk before, many canon claims said that the Doctor himself was the person who STOLE Deku's original quirk, which could've been Fire Breath or something like that.
His Quirk is Explosion (爆破), which allows him to make explosions from his hands by detonating the nitroglycerin-like substance he sweats; throughout the series, he learns various different ways to apply this.
Fans know that his name is Hisashi Midoriya and that his quirk is fire breathing.
