My Hero Academia's One For All is an incredibly powerful Quirk that was created when All For One gave a strength stockpiling Quirk to his younger brother, Yoichi, thinking he didn't have a Quirk. Little did he know that Yoichi actually had a Quirk that allowed power to be passed down, and the two Quirks combined to become what is known as the One For All.

Over the years, this Quirk has had many users, however, only Izuku Midoriya, the 9th user of this power, has been able to bring out its true powers. Under Izuku, One For All is at its strongest and within it lie several other Quirks that the former users of this power possessed.

Updated on January 30, 2023, by Rei Penber: One For All is the strongest of all Quirks in the world of My Hero Academia. Through its immense power, the likes of Deku and All Might have been able to topple even the toughest of foes. While the One For All quirk in itself is overpowered enough, it also offers quite a few other Quirks that have been laying dormant within it for the longest time. This list already goes over all the Quirks offered by One For All, however, this list has now been updated to include their utility as well.

6 Gear Shift

Gear Shift is the newest Quirk awakened by Izuku Midoriya during the events of the Final War arc. When his comrades were fighting for their lives, Deku arrived just in time on the battlefield and saved them and, in doing so, also unleashed a completely new power. Up until this point, he had awakened all the Quirks within the One For All except one, however, with the awakening of the Gearshift Quirk, he now has access to them all. This Quirk first belonged to the second user of One For All. When used, it allows the users to alter speeds instantaneously.

While on paper, this doesn't sound nearly as impressive as it really is, the fact that makes it truly scary is that it completely ignores the laws of inertia, as seen in the fight against All For One when Deku took him on in combat. Initially, this Quirk could not be used on big objects, however, as the One For All quirk boosts every single quirk, Gearshift gets boosted as well. That said, there is a time limit on the usage of this Quirk as it takes a massive toll on the body of the user. According to the second user of One For All, Deku can only maintain it for 5 minutes and after that, his body will start to weaken and potentially even die.

Gearshift Utility: 8/10

Gearshift is an incredibly overpowered ability and it has allowed Deku to contest evenly with the likes of all for one and, in moments, even overwhelm him completely. With its powers, combined with the other abilities that One For All offers, Gearshift is absolutely unstoppable. However, this Quirk is almost always left as a last resort because the toll it takes on the body of the user is excessive. Once utilized, Deku can only fight for 5 minutes and after that, his body will not be left in any condition to continue. With that in mind, the utility of this Quirk isn't all that high. Nonetheless, whenever used, it is most likely going to finish the job and for that reason, it scores high on the utility list.

5 Blackwhip

My Hero Academia Deku Manifests Blackwhip

The very first Quirk that Izuku Midoriya awakened was Blackwhip and he did so in the Joint Training Exam arc of the story. Not knowing what the power was, Izuku struggled to control it at the time, however, after significant training, his control over this power is just as good as One For All.

Blackwhip was originally the Quirk of the sixth user of One For All, Daigoro Banjo, and currently, it allows Izuku to produce tendrils of energy from his body that can be used to grapple onto things and even for long-ranged combat. With its powers, Deku can easily grab his enemies, lift others to safety, and even increase his own mobility, among many other things. Without a doubt, this Quirk is one of the most useful abilities that he possesses at the moment.

Blackwhip Utility: 7/10

Blackwhip was the first Quirk within the One For All that Deku awakened. Due to this Quirk's ability to produce webs of energy that can be used as ropes, this Quirk is quite useful. In combat, it can also be combined with other Quirks and is thus one of the best abilities that Deku possesses. As a Hero ability, its utility is certainly very high.

4 Float

Deku Float Quirk

Float formerly belonged to the seventh user of the One For All and the teacher of All Might, Nana Shimura. Just like every other Quirk, this one was passed down to Izuku along with One For All. During the Paranormal Liberation War arc, Deku was finally able to tap into its power when Shigaraki unleashed his Decay Quirk to destroy everyone around him.

As the name suggests, Float allows Deku to suspend himself in mid-air. When combined with the power of One For All, he can move in the air at high speeds, which makes it seem like he's flying. Deku's control over this power has dramatically improved over time.

Float: 7/10

Nana Shimura's Float is quite an incredible ability that allows Deku to levitate in mid-air. Considering that his main enemy is Shigaraki, who can cause decay without direct contact, this ability is priceless. It also allows him to fight in mid-air and makes him a much more versatile Hero and thus has high utility.

3 Danger Sense

My Hero Academia Deku Danger Sense Quirk

Also awakened by Deku in the Paranormal Liberation War arc, Danger Sense is quite a useful ability. It was formerly wielded by the fourth user of One For All, Hikage Shinomori. The powers of this Quirk are quite straightforward, as its name suggests.

It grants Deku a sort of sixth sense and allows him to sense any danger that is nearby. As long as the person has malicious intent, Deku will be able to detect it with ease. Those who don't have any ill intentions will not be picked up by this Quirk, even if they're an enemy. Initially, this Quirk caused a lot of pain to Deku when used, however, this can be lowered with further training.

Danger Sense Utility: 9/10

Danger Sense is quite possibly one of the most useful abilities that Deku has awakened. Ever since the Paranormal Liberation War Arc, it has given him the ability to sense all kinds of danger around him moments before something dangerous actually happens. Although it did cause him pain upon being used at first, that seems to have subsided with training and, thus, its usability is incredible in combat. As a Hero, sensing danger allows Deku to prepare for all situations and save as many people as possible. This Quirk is highly useful.

2 Smokescreen

Deku Smokescreen Quirk

Formerly belonging to the sixth user of One For All, Smokescreen is quite a useful Quirk that is now in the possession of Izuku Midoriya. He awakened this power after the events of the Paranormal Liberation War arc wrapped up and those close to him were finally made aware of the truth about his powers.

Smokescreen is a very useful ability as it allows Izuku to produce a very thick cloud of smoke from his body. This smoke can cause a lot of problems for the enemies as they can't pick up on Deku's location at all. At the same time, Deku can then catch them by surprise due to their obscured vision. The key to this Quirk is balance and, if used excessively, it can cause the same problems for Deku as it does for his enemies.

Smokescreen Utility: 5/10

Smokescreen was recently awakened by Izuku Midoriya and while it certainly is quite a useful Quirk, especially in combat, its utility isn't as high as the other abilities offered by the One For All. As a Hero, there aren't many instances where Deku needs to rely on it. In combat, it can certainly offer him an edge, however, given the power that One For All already holds, its need isn't all that high.

1 Fa Jin

My Hero Academia Deku Fa Jin Quirk

Fa Jin was formerly wielded by the third user of the One For All and after his death, this Quirk lay within One For All, only to awaken when Izuku received its powers. Out of all the extra abilities that One For All has, Fa Jin remains one of the most impressive.

By repeating regular motion, Fa Jin grants the ability to build up kinetic energy that can be stored within the body for later use. Once unleashed, it grants a significant boost in both strength and speed. The stored energy can be used by Izuku according to his will. What makes this Quirk terrifying is the fact that, when combined with 45% of One For All and the slinging of Blackwhip, the energy generated is equal to that of 100% of One For All.

Fa Jin Utility: 8/10

Fa Jin is a tremendous ability that Izuku possesses. This Quirk gives him extra power and, in combat, that always comes in handy. When combined with the likes of Blackwhip and One For All, it can mimic the same power that All Might once wielded. Fa Jin is, thus, highly useful and as One For All grows stronger, so does this Quirk. Against someone like Shigaraki, it will certainly come in handy.
