After this, All Might decided that Izuku had the potential to become a hero, with his help. He decided that he would grant Izuku his own Quirk to help him achieve his dreams. After ten months of training, All Might passed his Quirk, One For All, down to Izuku.
Nicknamed "Deku" by childhood classmate and middle school bully - Katsuki Bakugo, Izuku would later save him from a villain, in turn winning over the interest of All Might, Izuku's childhood idol and #1 hero, who in turn passes down his sacred One For All quirk to him.
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.
All Might is one of the most important people in Deku's life, and it's not just because he gives him the Quirk that allows Deku to become a hero. All Might is the reason why Midoriya dreams of becoming a hero at all, and it's thanks to All Might's training that Deku is ready to take on hero school.
Part of what makes One for All so powerful is its ability to accumulate and strengthen Quirks from previous users. Because of this, in truth, Deku has not one, but seven Quirks, stored in One for All's core and passed down from user to user.
One For All is one of the strongest Quirks in My Hero Academia, if not the strongest. It allows the super to stockpile incredible amounts of power within their body which, when released, grants a tremendous boost in power.
As of now, Deku has access to seven Quirks, namely One For All, Transmission, Fa Jin, Danger Sense, Blackwhip, Smokescreen, and Float. The basic gist of all these powers is that they all come from the previous One For All users, with their abilities becoming stronger throughout the generations.
According to Deku's mother, the inherited quirk Deku should've naturally received would've either been his father's quirk, breathing fire, or her own ability to levitate small objects.
Unnamed Fire Breath Quirk: Hisashi's Quirk allows him to breathe fire.
The speculation here is that Izuku Midoriya was never actually quirkless - in fact, quite the opposite: he had a quirk that was powerful enough to attract All For One's attention, and Dr. Ujiko stole it, informing the unaware Midoriya family that Izuku simply didn't have one.
According to the events of My Hero Academia so far, Deku grew up without a Quirk. He was given the OFA Quirk when he met All Might. The series does give an explanation for why Deku was deemed Quirkless. With that said, more than a few fans are skeptical about it.
No. Deku's father hasn't been shown yet, but he has a fire-breathing Quirk. I doubt that All For One would conceive any children. It just doesn't seem like him.
7 Izuku Midoriya (Temporarily)
The protagonist of My Hero Academia, Izuku Midoriya was the first Quirkless character to be introduced.
Yes but no, if you are referring to base OFA that is always shown then yes but OFA is composed of 6 different quirks (7 counting the strength boost) so no user has used 100% of its power seeing as it's only the strength boost that we see used.
In order to try to protect people, Izuku left UA and is working with All Might and an elite squadron of heroes as he goes through his Batman phase—better known to fans as Dark Deku.
He then decided to pass on a Quirk power named, One For All to Midoriya by getting the Quirkless protagonist to consume some of his DNA via eating a strand of his hair [2]. This results in Midoriya inheriting All Might's powers and attending U.A. High.
The Mother of Quirks ("個性"の母, "Kosei" no Haha?), as she came to be known posthumously, was the mother of Chikara Yotsubashi, also known as Destro, founder and former commander of the Meta Liberation Army. She got this title because she was the first person to use the word "Quirk" to describe Meta Abilities.
Manga Debut
Akazuko Midoriya (fan-made character) is the eldest son of Deku (Izuku Midoriya) the worlds greatest superhero he is reffered to as ''next''. he is one of the main characters striving to achieve his dream of becoming the number 1 hero,after receiving one of the worlds most powerful quirks.
Given how the plot is being discussed this late in the story, it could be a hint towards the identity of Deku's father, Hisashi Midoriya, being a heteromorph himself. The manga is currently focusing on the struggles a heteromorph faces through the perspective of Shoji.
The first person to manifest a Quirk was a newborn baby in the city of Quig Quig, China, who had the ability to emanate light from their body.
One For All: All Might inherited the Quirk called "One For All." It would allow him to stockpile an enormous amount of raw power, allowing him to significantly enhance all of his physical abilities to a superhuman level.
Why does Deku become a villain? The concerns surrounding Deku grew after he awoke his new quirk Black Whip, originally belonging to Daigoro Banjo, one of the inheritors of One for All. Deku was unable to control its powers and its generally dark and intimidating image didn't help his case.
The seventh user of One For All, Nana Shimura is a superheroine with the Quirk, Float. She was a friend of Gran Torino and All Might's mentor, teaching him in an optimistic manner.
