Izuku Midoriya is the main protagonist of Kohei Horikoshi's My Hero Academia. Born Quirkless, Midoriya had little future as a Hero, however, his bravery and the drive to help those in need with a smile made All Might, the strongest Hero of all time, choose him as his successor. Inheriting his strength, Izuku Midoriya has since gone on to achieve incredible things.
Along with the power that All Might passed down to him, Midoriya has also attained some incredible abilities. With time, his powers have only grown, and currently, he's strong enough to hold his own against some of the very strongest people in the entire series with his many abilities.
Updated by Rei Penber on March 17, 2023: My Hero Academia is currently closing on its end and that means all the characters that the fans hold close to their hearts are finally fulfilling their potential as well. With the Final War arc having begun, My Hero Academia has seen the likes of Deku and Bakugo, among others, grow significantly powerful. Deku, especially, is closing on his peak and has awakened powers that fans never expected him to possess. He is someone worthy of being considered as the strongest hero already and still has more room left to grow. In the Final War arc, Izuku Midoriya has gained several new powers. While this list already goes over the strongest abilities that he has up his sleeve, Deku has now mastered more abilities and, for that reason, this list has been updated accordingly.
13 Keen Intellect
Deku is one of the smartest people in the world of My Hero Academia. While he didn't have any Quirks bestowed upon him at birth, he did have a smart head on his shoulders. Even before becoming a Hero student, he had already kept a record of the strengths and weaknesses of the majority of the Heroes and studied them to his advantage.
Growing up, Izuku only used this intellect to his advantage in the many battles that he fought, and using his extraordinary creativity, turned even the toughest of situations in his favor, showing his immense skill as a Hero. Out of all of Deku's powers, his intellect might just be the most underrated one. However, it is also one of the most useful and seen as early as when Deku used it to gain admission into U.A during his entrance exam. Since then, his keen intellect has only grown and, currently, he is one of the smartest characters in the entire series
12 Willpower
Just like the majority of shonen protagonists, Deku possesses incredible willpower. This has been seen on countless occasions in the story, such as when he aimed to become a great Hero despite not having a Quirk.
Izuku has fought against overwhelming odds and conquered the toughest of situations, all thanks to his incredible willpower. He's beaten some of the most powerful enemies, such as Muscular and Chisaki, and even fought the likes of Shigaraki Tomura by putting his life on the line.
11 Leadership
Being the protagonist of My Hero Academia, it is no surprise that one of the very best Deku powers is his leadership ability. Often, in the toughest of situations, he takes charge of the situation and ends up leading his classmates into battle.
Using his strategic mind, Izuku often lays out plans and makes sure everyone sticks to them. Due to this characteristic of his, Izuku has the trust and the faith of all those around him, including strong characters such as Bakugo and Shoto Todoroki as well.
10 Smokescreen
Smokescreen is an emitter type of Quirk that once belonged to the sixth user of One For All, En. Later, this power awoke within Izuku Midoriya as well and has only grown stronger since due to Quirk Singularity. Smokescreen allows Midoriya to produce a thick smoke from his body to keep himself from the sights of his enemies and also take them by surprise.
The smoke produced can cover a very wide area and is usually enough to cause problems to anyone. Too much smoke, however, can cause navigational problems from Deku as well. Maintaining a perfect balance of its power is the key to using it as efficiently as possible.
9 Danger Sense
Formerly wielded by Hikage Shinomori, the fourth user of One For All, Danger Sense is quite a special ability. As the name suggests, this power allows the user to sense danger in their immediate surroundings. When used properly, it grants a sixth sense ability to the user and thus warns them of danger nearby before it even arrives.
It does, however, cause mild pain to the user when triggered. According to Deku, this can be controlled with enough training. After Hikage, this Quirk awoke within Izuku Midoriya. As expected, the powers of this Quirk under Midoriya is several times greater than it was under Hikage Shinomori.
8 Float
Float was the Quirk of the seventh user of One For All and the teacher of All Might, Nana Shimura. After being passed down to Izuku Midoriya, this power awoke within him during the Paranormal Liberation War arc while fighting against Shigaraki Tomura.
As the name suggests, Float allows the user to levitate in midair. While the basic power that it offers is quite simple, when combined with the stockpiled energy of One For All, it can be used to fly at high speeds, making it one of the most special powers in the world of My Hero Academia.
7 Blackwhip
Blackwhip belonged to the sixth user of One For All, Daigoro Banjo. In the current timeline of My Hero Academia, it was the first extra Quirk that Deku awakened during the events of a training arc. Blackwhip is quite a useful power, and it allows Midoriya to produce ropes of energy from any part of his body.
Although this ability wasn't as powerful under Daigoro Banjo, thanks to it having grown over the years, it is incredibly strong under Midoriya. Blackwhip appears to be strengthened by emotions, meaning the more intense they are, the stronger it gets. It remains to be one of Izuku Midoriya's strongest powers so far and will continue to grow as he grows stronger as well.
6 Fa Jin
Used formerly by the third user of One For All, Fa Jin is quite an incredible power that Izuku Midoriya awoke after the events of the Paranormal Liberation War arc. This Quirk allows him to store kinetic energy by repeating certain movements and making use of it at a later time. When released, Fa Jin grants a tremendous boost in power and speed, making the user much more dangerous in combat.
As with every other Quirk, Fa Jin is much stronger under Izuku Midoriya than it was under his predecessor. When combined with One For All and Blackwhip, Fa Jin allows Midoriya to produce strength rivaling 100% of One For All just at 45%, which just goes to show that it is an incredible ability.
5 One For All
Izuku Midoriya's strongest Quirk is, without a doubt, the One For All. This Quirk first belonged to All For One's brother, Yoichi. After him, there have been eight more users of these powers. All Might, the eighth user of One For All, passed it down to Izuku Midoriya, making him the 9th and the final 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. When mastered, One For All becomes a power greater than even All For One, which just goes to show that this Quirk is easily among the greatest to ever exist.
4 Transmission
Transmission is the last Quirk that Deku inherited from the vestiges of One For All. This ability is extremely powerful and awakened during the Final War arc. Being the final ability that he awakened, this one is rather special and, while at first glance, it doesn't look as impressive as the others, its application with other Quirks certainly makes it immense. Transmission allows Deku to change the way acceleration works. Simply put, Deku can alter the acceleration of any object that he touches. While that doesn't seem all that impressive, the fact that it can ignore every law of inertia certainly makes it very scary. When this Quirk was being used by the second user of One For All, it was not deemed to be powerful and only worked on small objects.
However, now, this Quirk has grown several times stronger, thanks to being passed down from generation to generation. Transmission is now capable of working on much larger objects and humans as well. Its power was used by Deku against Shigaraki and it proved to be strong enough to give him trouble. When combined with other Quirks, it was able to beat back Shigaraki, which is certainly very impressive, considering the fact that the latter is among the very strongest in the world of My Hero Academia right now. However, this ability certainly does have a catch. It cannot be used all the time and, thus, puts the user on a time limit. Thus, Transmission can only be used as a last resort and in the fight against Shigaraki, Deku only had 5 minutes.
3
Overdrive
Overdrive is an exceptionally powerful ability in the arsenal of Izuku Midoriya. It might even be the strongest power that he has up his sleeve right now. Overdrive activates when Deku uses transmission with Fa Jin.
When he uses the ability known as Overdrive, Deku is able to accelerate his own strikes significantly and go beyond the 100% power of the One For All. According to what the manga tells the fans, every strike of Deku in this form equals 120% of the power of One For All, which is well beyond the peak of this Quirk that fans know exists.
2 Faux 100%
Faux 100% was developed by Izuku shortly before the final war arc. This ability of his is extremely powerful and sees him make use of his keen intellect to get the most out of One For All. Faux 100% is simply Deku combining 45% of One For All with the kinetic energy that he has stored within himself with Fa Jin. The result is a surprising power boost of the One For All which can be considered equal to 100% of the actual Quirk without actually using all of it.
This means that Izuku Midoriya can actually access 100% of the One For All without breaking any of his bones or pushing his body to extreme limits. In this form, Deku can unleash attacks with blinding speeds and overpower any enemy that he is fighting. Undoubtedly, this is a genius application of his Quirks and possibly the best combination that the fans have seen so far.
1 Blackchain
Another Quirk combination that Deku uses is Blackchain. This one sees him combine Blackwhip with Fa Jin. Fans already know Blackwhip to be a Quirk that allows Deku to produce rope-like energy tendrils from his fingers, capable of binding others, among many other things. When combined with the power of Fa Jin, Deku is able to produce a chain that is even stronger than Blackwhip.
Blackchain is powerful enough to wrap around any target and hurl them over great distances at a tremendous pace. This ability is very versatile and allows him to both attack his enemies and aid his allies at the same time. Deku used this ability against Tomura in the Final War and was able to hurl him across the battlefield. Once again, this just goes to show that Deku is still evolving as a fighter and that he is far from hitting his peak. The fact that fans have not seen the actual fight just yet means that Izuku Midoriya will continue to develop this ability further and perhaps come up with new skills as well.
