Hellflame is the Quirk of the current Number 1 Hero, Endeavor. It goes without saying that this Quirk is very powerful, as it has helped Endeavor deal with some of the most vicious villains, such as the High-End Nomu. As of now, Hellflame is far more powerful than the level at which Midoriya can use the One For All.
Ojiro's quirk is almost completely useless. His tail may be able to propel him across certain obstacles and swat his opponents, but, unlike Shoji, it is impossible to surprise his opponents with his tail since he cannot retract it.
Izuku was raised primarily by his mother Inko, who has the ability to make small objects float towards herself. His father, Hisashi, whose quirk allows him to breathe fire, is not seen due to him working abroad in the United States.
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.
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.
While not every One For All user has had multiple Quirks, some of them did indeed possess more than one, with the first user of One For All, Yoichi Shigaraki, being the prime example. He has access to two Quirks, as did Hikage Shinomori, and Diagoro Banjo.
The seventh user of the One For All Quirk, Nana Shimura was quite a powerful woman, thanks to her receiving the Quirk from En before he died. Nana herself had the power of the Float Quirk which, as the name suggests, allowed her to levitate in mid-air.
The only way Midoriya can use One For All at 100 percent without training his body is with the help of Eri's quirk. Eri's quirk, Rewind, allows her to bring anyone's physical body to its previous state.
A "blank Quirk" is a Quirk factor that requires the user to gradually build up a certain resource to fuel its power. An analogy would be if Neito copied a car but only the vehicle itself, with no gasoline inside. He cannot refill the car's gas tank, so to speak, and thus the power does no good in his hands.
The three main types of quirks are known as emitter, mutant and transformation type. The emitter-type is known to not cause any abnormalities to the quirk user's body, whereas the mutant-type does lifelong physical abnormality to the body.
Fans know that his name is Hisashi Midoriya and that his quirk is fire breathing. It's assumed that Hishashi's fire-breathing quirk isn't as eye-catching as Dabi's flames since Inko brushed it off at Izuku's doctor's appointment as a child. Currently, Hisashi's work has taken him abroad, leaving Inko and Izuku alone.
