Midoriya Izuku, also known as Deku, needs no introduction as the successor of the number one pro hero, All Might. However, before earning the title, he was just a quirkless crybaby with a big dream of becoming a hero.
Fortunately, his wish came true when All Might passed on the “One For All” quirk to him. This quirk is known for its unique ability to stockpile power and boost the physical strength and speed of its user.
Deku possesses a total of seven different quirks, which were inherited from the previous users of One For All. These quirks have been passed down through generations from the very first user, Yoichi Shigaraki, to the current (ninth) user, Midoriya Izuku.
With the accumulation of these quirks, Deku has become an even more formidable hero, capable of taking on the most powerful villains.
Here are Deku’s One For All Quirks ranked from worst to best.
7. Smokescreen Is Merely Ninja Smoke Bomb 2.0

At the bottom of our ranking, yet still vital, is the quirk, Smokescreen. Once wielded by the sixth user of One For All, En, it now aids Midoriya Izuku in his quest to uphold justice.
While its capabilities aren’t lethal or exceedingly powerful, its utility lies in its subtlety and tactical advantage. It essentially transforms Deku into a living smoke bomb, shrouding his surroundings in thick, opaque smoke, which can be incredibly useful in creating diversions, executing surprise attacks, or facilitating swift escapes.
However, the utility of this quirk comes with a caveat – overuse can obscure the user’s own vision, diminishing its effectiveness. Yet, when paired with a powerful offensive quirk, Smokescreen’s strategic potential truly shines.
6. Danger Sense, More Like Spidey-Sense on Steroids

The sixth spot is occupied by Danger Sense, a quirky, intuitive alert system that increases the survival and combat potential of One For All. Originally possessed by Hikage Shinomori, this quirk alerts the user to imminent threats through sharp, neurological impulses.
Danger Sense offers a heightened level of awareness, even enabling the user to anticipate an enemy’s next move.
However, its predictive capabilities are not without limitations. It may falter against exceedingly quick attacks and only triggers in response to malevolent intentions. This means an enemy with well-masked ill intentions could slip past undetected.
Despite these limitations, Danger Sense remains a crucial defensive tool in Deku’s quirk collection.
5. Float – Levitation Made Easy

Ranking fifth, Float is a simple yet highly effective quirk that gives the power of flight. Once owned by Nana Shimura, All Might’s mentor, and the seventh user of One For All, this quirk grants Deku the ability to levitate and control his aerial movements.
This newfound agility quickly proved invaluable, offering a significant upgrade from his ground-based Shoot Style technique. By infusing Float with One For All, Deku can reach extraordinary speeds in the air, making it an extremely potent weapon during battles.
Moreover, Float also enables Deku to rescue his friends from precarious situations, such as evading Shigaraki Tomura’s Decay Quirk.
Despite its straightforward nature, Float drastically amplifies Deku’s combat capabilities and versatility.
4. Black Whip Is the Most Versatile Quirk in Deku’s Arsenal

Occupying the fourth spot, we have Black Whip – the first additional quirk that Deku unlocked in his One For All journey.
Initially possessed by Daigoro Banjo, this quirk enables the generation of energy tendrils that can be manipulated freely. This opens a world of possibilities, both offensively and defensively. Offensively, it can grasp and hurl objects, ensnare enemies, and prevent their escape.
Defensively, it acts as an extension of Deku’s mobility, enabling him to swing around objects much like Spider-Man.
The dynamic nature of Black Whip makes it a truly integral part of Deku’s arsenal.
3. The Unnamed Stockpiling Quirk is The Genesis of One For All

The unnamed stockpiling quirk serves as the foundation of One For All, holding the third spot in our ranking.
This quirk is the epicenter of raw power that permits superhuman feats of strength, speed, and agility. It offers the ability to control the amount of power unleashed and focus it on specific body parts.
However, using this quirk recklessly can lead to severe injuries, underlining the importance of control and restraint.
Despite the potential risks, this stockpiling quirk remains an incredibly adaptable ability that can augment the user’s existing quirk, opening up diverse tactical possibilities.
2. Gear Shift Alters Speed With a Single Touch

Gear Shift, the final quirk Deku unlocked, grants the intriguing ability to manipulate the speed of anything it touches, including Deku himself.
Initially, it could only affect small objects, but the stockpiled power of One For All enhanced it, turning it into a formidable force.
The major downside is its short duration and the subsequent physical exhaustion it imposes on the user.
Despite this, the tactical advantage Gear Shift can provide in a crucial moment of battle makes it a powerful weapon in Deku’s quirk repository.
1. Fa’ Jin Fuels on Kinetic Energy

Fa Jin is the strongest quirk in Deku’s One For All arsenal. This quirk allows the user to build and store kinetic energy by repeating motions and releasing it as a powerful burst of speed and strength.
Fa Jin allows its user to regulate the amount of energy released. This feature makes it possible to achieve multiple bursts of speed and power, with recharging as simple as repeating a certain motion.
When combined with 45% of One For All, Fa Jin generates energy equal to 100% of One For All without any adverse effects on the user’s body.
There is not much information about the constraints of Fa Jin, but we know that it takes a significant amount of time to build up the necessary kinetic energy for the quirk.
