In a world where people can blow up buildings with a flick of the wrist or liquify metal with their breath, it’s easy to forget that not everyQuirkin My Hero Academia was born to dominate a battlefield. Some are quiet, peculiar, or even seemingly useless in combat, but that doesn’t mean they aren’t fascinating.
My Hero Academia: 8 Best Character Arcs
My Hero Academia thrives on growth and redemption. These character arcs showcase the struggles, sacrifices, and triumphs that define true heroism.
Harmless Quirks are a strange breed in the world of ProHeroes. They don’t cause explosions, they don’t summon storms, and they rarely send villains running. But what they lack in brute force, they often make up for in uniqueness, support utility, or simply, a touch of comedy. And in many cases, these Quirks say more about the creativity of the show’s world than the flashiest attacks ever could. Here are 7 harmless quirks in My Hero Academia.
7Inko Midoriya
Unnamed Object Attraction Quirk
Inko Midoriya’s Quirk doesn’t scream power, it whispers convenience.
Her ability allows her to attract small objects toward herself, and while its exact name remains unknown, it’s typically referred to as an “Object Attraction Quirk.” When we first see her use it, she’s pulling a cup across the room, a gesture so subtle and mundane it would be easy to miss entirely.
But what makes this Quirk charming is how harmless it is. There’s no offensive capability, no combat utility, and no potential for widespread destruction. It’s the kind of ability you’d want in daily life, cleaning up without standing up, or fetching the TV remote from across the room.
And yet, this small, gentle Quirk birthed a son who would go on to inherit One For All.
6Shino Sosaki
Shino Sosaki, also known as Mandalay of the Wild, Wild Pussycats, possesses a Quirk called Telepath. It allows her to communicate directly into the minds of others, transmitting thoughts over long distances without the need for devices or shouting.
This Quirk can’t harm, push, stun, or destroy, all it does is send messages. But in the world of heroes, where coordination can mean life or death, that alone makes it incredibly valuable.
What’s especially interesting is that Telepath doesn’t work both ways. It’s a one-way link; she can send thoughts, but she can’t receive them. In a way, that limitation makes her ability even more harmless. She isn’t reading minds, and she isn’t manipulating thoughts. She’s simply speaking, quietly and clearly, in the chaos ofbattle.
We saw this in action during the Vanguard Action Squad invasion in Season 3, where she was able to coordinate students and heroes amid the forest ambush
5Mirio Togata
Permeation
At first glance, Mirio Togata’s Quirk, Permeation, doesn’t feel harmless at all. It lets him phase through matter, allowing him to walk through walls, avoid attacks, and even sink into the ground.
But what makes Permeation harmless isn’t what it does, it’s what it doesn’t do. It doesn’t let him hit harder, burn enemies, or immobilize anyone. In fact, it renders him completely intangible. He can’t even breathe or see while phasing, and the moment he activates it fully, his clothes fall off because they’re not part of his body.
It’s a logistical nightmare to use. That’s why, for most of his life, Mirio was considered a failure, until he turned it into a strength.
My Hero Academia: 10 Best Teachers, Ranked
From Hawks to Aizawa, these are the very best teachers in My Hero Academia.
He didn’t survive battles because Permeation was powerful. He did it because he was skilled. The quirk didn’t make him a top student at U.A.’s Big Three, his obsession with precision, timing, and raw physicality did. It took hundreds of failed experiments, bruises, and training sessions for him to master its mechanics.
So yes, Permeation looks strong in his hands, but it’s not the Quirk that’s powerful.
4Shota Aizawa
Aizawa’s Quirk, Erasure, might be the most debated entry on this list. After all, what’s “harmless” about a Quirk that can shut yours down in an instant?
But the truth is, Erasure doesn’t hurt anyone. It doesn’t immobilize your limbs, burn your skin, or punch you across the room. It just takes away your ability, temporarily and only while Aizawa is staring at you without blinking.
And even that has drawbacks. If you’re a mutant-type Quirk user, like Tsuyu or Shoji, your body’s physiology doesn’t change. Aizawa can’t make wings disappear or erase tails. His Quirk is purely suppressive, not destructive.
In a sense, it’s more like a deterrent than a weapon. In the hands of someone like Aizawa, it becomes surgical, a first-strike tool that levels the playing field.
But without his tactical genius, his scarf skills, and his terrifying stare, Erasure is just that: harmless. A blink, and it’s over.
3Emi Fukukado
Ms. Joke’s Quirk is called Outburst, and it’s exactly what it sounds like; she forces people to laugh uncontrollably.
It doesn’t hurt them. It doesn’t knock them out. It doesn’t even leave a bruise. But in the right moment, it can completely disarm someone.
We saw her jokingly flirt with Aizawa during the Provisional License Exams, but make no mistake, Emi Fukukado is a skilled Pro Hero. Her Quirk might seem like a punchline, but it’s surprisingly clever in execution.
If you can’t stop laughing, you can’t concentrate. You can’t aim. You can’t even breathe properly. It’s harmless in every way… and yet psychologically disruptive.
That’s the magic of Outburst. It’s an emotional grenade. Instead of rage or fear, it triggers joy, weaponized joy.
2Tatami Nakagame
Telescopic
Tatami Nakagame’s Quirk, Telescopic, lets her retract into herself like a turtle, arms, legs, torso, and all. She can curl up and compress her body for defense or mobility.
It’s one of the quirks that caused fans to go, “Wait… that’s it?”
And yes, that is it.
There’s no offensive use, no energy blasts, no control over elements. She can’t hurt anyone. At best, she can roll into tight places or avoid damage. It’s useful for evasion or hiding, but in a head-on battle, Telescopic doesn’t give her an edge.
Still, her inclusion in U.A.’s hero course speaks volumes. The faculty saw something worth training, maybe her quick thinking, or the way she uses her Quirk creatively to survive.
1Mei Hatsume
Mei Hatsume isn’t a fighter. She’s an engineer. Her Quirk, Zoom, allows her to magnify her vision up to five kilometers.
She can’t bend metal, fly, or hurl objects with her mind. But she can see things others can’t, literally.
In a series like My Hero Academia, where physical might often defines ability, Mei stands out for using her harmless Quirk to design support equipment that heroes rely on. Her gadgets aren’t just toys, they’re survival gear. From mobility enhancers to combat armor, she builds the very tools that bridge the gap between Quirk and strategy.
It’s not her Zoom that makes her formidable. It’s her mind.
She turned a simple visual enhancement into a career that supports the entire pro hero system.
