In thevibrant worldof My Hero Academia, extraordinary abilities known as “Quirks” define a society where the supernatural has become ordinary. While some heroes and villains wield flashy, complex powers that bend reality itself, there’s something particularly fascinating about Quirks built on simpler foundations.
My Hero Academia: 7 Weakest Quirks
Not all Quirks are powerful. Some are more of a burden than a gift, leaving their users struggling. Here are 7 Quirks that fall on the weaker side.
These straightforward abilities might lack the immediate wow-factor of more elaboratepowers, but they often reveal something profound about heroism itself, that true strength comes not from complexity, but from how one develops and applies their natural gifts. These 6 Quirks demonstrate that in the hands of determined users
6One For All
At its core, One For All is as straightforward as a Quirk can get: it grants the usersuperhuman strength, speed, and durability. It’s the kind of power you’d imagine in a classic superhero comic, punch harder, move faster, take bigger hits. No illusions, no tricks, no elemental manipulation. Just pure, unfiltered physical might.
What complicates One For All is its legacy. Originally formed from the fusion of a power-stocking Quirk and a Quirkless individual, it was passed down from one successor to the next, each user adding to its strength like a rolling snowball. Midoriya, the current holder, is its ninth user. But for nearly six generations, the power was used without the added complications we see today.
Back when All Might wielded it, there were no secondary Quirks. No Blackwhip, no Float, no Danger Sense. Just a fist powerful enough to change the weather.
5Invisibility
Toru Hagakure
Her quirk doesn’t shoot lasers, control elements, or alter gravity. It just makes her invisible, permanently. While the premise is basic, the strategic uses of Invisibility in My Hero Academia have become more nuanced over time.
Toru was born with this Quirk and has never been visible, not even to herself. That alone raises quiet, painful questions about identity and self-perception, especially for a teenage girl trying to understand who she is, literally unable to look in a mirror. It’s a simple power that comes with quiet emotional weight.
But on the battlefield, her Quirk turns her into a natural scout and stealth attacker. Whether sneaking up on villains or catching opponents off-guard in training, she turns an absence into an advantage. She’s shown real growth, especially during the Paranormal Liberation War arc, where she blinds a villain using her own light-reflecting gloves, a clever workaround using tech with her Quirk.
Neito Monoma
Neito Monoma’s Copy ability sounds almost too good to be true: touch someone, and you may use their Quirk for a limited amount of time. On paper, it’s a dream. But in execution, it’s surprisingly restricted and situational, making it a perfect example of a simple Quirk with untapped potential.
Monoma can hold multiple Quirks at once (up to four), but there are rules. He can’t use Quirks that require long-term buildup, like One For All, and he has no access to the target’s experience or instincts when using the Quirk. If he copies a power like Explosion or Half-Cold Half-Hot, he doesn’t instantly know how to use it well. That’s a huge limiter.
My Hero Academia: 7 Best Harmless Quirks, Ranked
Not all Quirks are built for battle. Some are harmless, quirky, or oddly useful in daily life. Here’s a look at My Hero Academia’s safest abilities.
Still, Monoma makes the most of it. He studies his classmates, learns the mechanics behind their abilities, and adapts in real time. His brilliance isn’t in the Quirk, but how he uses it. During the Joint Training Battle arc, he used Copy to chain together multiple powers, creating unpredictable offense and solid defense.
Tomura Shigaraki
Tomura Shigaraki’s Quirk doesn’t require aim, precision, or stamina. Just touch, and whatever’s under his fingers crumbles to dust. Decay is as brutal as it is straightforward, and that’s what makes it terrifying.
Originally, Shigaraki needed to place all five fingers on a target to activate the Quirk. But as he grew stronger, that limit dissolved. In the Paranormal Liberation War arc, his Decay reached the point where touching the ground with a single hand caused entire blocks of cityscape to disintegrate, buildings, people, heroes, everything.
There’s no flash or spectacle. No swirling energy or dramatic chant. Just a hand, a moment, and the end of whatever it touches.
The simplicity of Decay is what gives it weight. It’s symbolic of Shigaraki’s inner destruction, his trauma, his hatred, and his longing to wipe away a world that failed him.
Itsuka Kendo
Kendo Itsuka’s Big Fist Quirk allows her to enlarge her hands to massive proportions, a power that might seem basic but carries tremendous utility in combat situations.
As the Class 1-B representative, Kendo has demonstrated remarkable creativity with her Quirk. Her enlarged hands provide enhanced striking power and serve as shields capable of protecting herself and others from danger.
During the Joint Training Arc, Kendo showcased tactical brilliance when she used her Quirk to defeat Momo Yaoyorozu, one of Class 1-A’s most intelligent students. By creating air pressure with her giant hands, she dispersed Momo’s smokescreen strategy
Mashirao Ojiro
Quirk doesn’t scream power. It’s just… a tail. A strong, prehensile one, but still. a tail. He can swing it, balance with it, and deliver powerful strikes. That’s it. No explosions, no energy blasts. Just an extra limb.
But what Ojiro lacks in flash, he makes up for in martial discipline. He’s trained in traditional martial arts, adapting his fighting style around his Quirk to create a combat form that feels natural and highly effective. If you stripped away all the superhero aesthetics, Ojiro would still be dangerous in a street fight.
