It is no secret that the main character of My Hero Academia is Izuku Midoriya, who goes by the hero name “Deku.” During the early part of the series, he was revealed to be quirkless and was one of the few people in the world that didn’t have any powers, even though he wanted to develop a quirk so that he could become the same kind of hero that All Might was. Deku received the same powers that All Might did. Deku’s quirk was discovered in My Hero Academia.

Deku was granted his quirk in the third episode. All Might decided that he wanted One For All to be passed on to Izuku Midoriya because he recognized that he was a true hero. Deku was then named the new inheritor of One For All.

Deku did not have any quirks and could only have one quirk due to One For All’s ability to be passed from one person to the next. Nevertheless, Deku’s body wasn’t made for this quirk, and that was why he needed to work hard to become stronger so that he could use One For All effectively. Now, let’s look at when and how Deku got his quirk in My Hero Academia.

What Is Deku’s Quirk In My Hero Academia?

The entire premise of the My Hero Academia manga and anime relies on the fact that the world’s population has developed powers called quirks, which are abilities that people are naturally born with. Only around 20% of the entire world population doesn’t have any quirk, and that means that almost everyone in the MHA world has a special ability. People with quirks are often trained to be heroes in order to use their talents for the good of society.

Izuku Midoriya was the main protagonist of the series. He was described as someone who idolized All Might, a strong hero from the world who was also the symbol of peace in Japan. He admired All Might so much, he wanted to be like him as a grown man. However, he learned at a very young age that he couldn’t become a hero because he didn’t have any quirks, and that was a heartbreaking moment for the young character.

Deku met All Might as a result of the series. That was when he found out about All Might and how the character had become so weak that he couldn’t maintain his muscular form for an extended period of time. It didn’t take too long for All Might to choose Deku as the next successor of his quirk, which is called One For All.

Deku, like All Might, has the same quirk in the sense that he was handed it by the most powerful hero in the entire world. That means that Deku has what is potentially the strongest quirk in the entire world, but with the problem that he wasn’t cut out for this quirk due to his weaker body.

The basic idea behind One For All is that the quirk allows users to increase their physical abilities by using energy stored in the quirk. Neito Monoma, who has the ability to copy quirks, later confirmed that Deku’s quirk is a stockpiling quirk that allows him to stockpile enough energy that he could use as his source of strength. This quirk allows you to store power within One For All.

All For One, a supervillain in MHA’s criminal underworld, gave his younger brother an ability to stockpile quirks so that he could force him to follow his lead. However, what he didn’t know was that his brother’s quirk was the ability to pass his quirk to other people. The stockpiling quirk and this quirk made One For All. This quirk continued to stockpile energy, passing it from the very first user.

As such, when Neito copied Izuku Midoriya’s quirk, he couldn’t do anything with it due to the fact that he hadn’t stockpiled enough power in his body to use it effectively. Deku, the ninth user of this quirk, had enough power.

It was also revealed later on in the fifth season of the series that Deku’s quirk stockpiled not only energy but also the quirks that its previous inheritors also had. It was only during Deku’s time that the “core” of One For All had already grown big enough that Midoriya was now able to gain access to the quirks of all of the previous users of One For All. Such quirks include:

• FaJin – the ability to build up kinetic energy for explosive movements.
• Danger Sense – the ability to sense threats within the surrounding area.
• Blackwhip – the ability to manifest tendrils of black energy that can be used for grappling.
• Smokescreen – the ability to generate a cloud of smoke.
• Float – the ability that allows the user to suspend themselves in the air.

When Does Deku Get His Quirk In My Hero Academia?

His quirk was actually discovered by Izuku Midoriya in both the anime and manga. He received his quirk in the anime’s third episode, when All Might declared him the new inheritor for One For All. Deku had to go through ten months of physical training before he was able to inherit this power from All Might.

Midoriya was unable to access his other quirks until later in the series. Blackwhip first appeared in episode 98, after Midoriya accidentally used the device during the joint training of Classes 1-A and 1-B.

Deku was slowly gaining access to his quirks in the later portions of the manga as he began to understand how One For All worked and why he was not able to access the quirks the other inheritors had.

The origin of this phenomenon can be traced back to the time Izuku Midoriya received One For All by All Might. All the other quirks were stored within One For All due to the stockpiling quirk being one of the original quirks. Basically, the quirks from other users are kept within One For All.

How Did Deku Get His Quirk In My Hero Academia?

Deku was born with his quirk during My Hero Academia’s earlier portion of the anime. It was the attack of a slime villain that decimated the city and threatened the life of Katsuki Bakugo.

Izuku Midoriya was in the area. Bakugo survived, but Midoriya was the only one who attempted to save him. Bakugo was quite a bully, so Midoriya did not have the right to save him. Bakugo’s inner hero made him want to save him because that is what All Might and a true hero would do.

All Might appeared just in the right time to save Midoriya and Bakugo, and it was also the first time Deku met his childhood hero. All Might was convinced that Midoriya was the man he needed to pass on his quirk to. He was impressed at the boy’s willingness to do anything, even if he didn’t have a quirk.

Episode 3 of the anime shows All Might making Izuku Midoriya his successor. However, he had to go through intense physical training in order to prepare his body for One For All. This required that the user be physically strong enough to deal with the energy contained within the quirk. 

All Might ordered Midoriya to eat a strand from his hair after ten months. This was because it was impossible to pass One For All on to someone else unless they eat the DNA of the current inheritor. This was how Izuku Midoriya became the new inheritor for One For All.
