10 Foresight allowed Nighteye to see the future

Sir Nighteye was once All Might's aide and now runs his own Hero Agency. Not just anyone could stand alongside All Might in his prime, but with a Quirk like Foresight, it's quite easy. Foresight allows Nighteye to see anyone's future for up to an hour (at his discretion). For the most part, his visions are infallible. But Izuku Midoriya proves that his visions are only probable futures, not certainties.

Still, Foresight is an indispensable tool for reconnaissance and knowing when an opponent is going to attack. With Foresight, Nighteye can predict the villains' movements and act accordingly. Nighteye sadly loses his life in season 4 of My Hero Academiabut the memory of his incredible Quirk is a testament to how essential he was.

9 Dark Shadow is somehow sentient

Dark Shadow is one of the more interesting Emitter Quirks, as sentient life seems to emanate from it. Fumikage Tokoyami has Dark Shadow attached to him, but Dark Shadow has thoughts and emotions of its own. Dark Shadow's true nature is never explained, but there are a few things fans learn about this Emitter Quirk as the story progresses. The most important part about Dark Shadow is that it is easiest to control, but weakest, in light.

It's much more powerful (and dangerous) in the dark. Tokoyami works hard to gain the strength needed to control Dark Shadow in the dark, but it takes a lot of training. Tokoyami also discovered a way to make Dark Shadow act like wings so he can fly. There are still a lot of mysteries about this Quirk, but that's what makes it one of the most dynamic Emitter Quirks.

8 Erasure is an invaluable peculiarity

Shota Aizawa's Quirk isn't flashy, but it is one of the most useful and powerful Quirks. Aizawa's Quirk is Erasure. With it, he can cancel out anyone's Quirk as long as he makes eye contact with them while activating it. As long as Aizawa keeps his eyes locked on his opponent, their Quirk will remain canceled out.

The downside to this Quirk is that Aizawa's eyes regularly dry out, and if he blinks, the person's Quirk returns to them. Aizawa has become proficient at pushing his limits to keep villains' Quirks in check, but he's not perfect. Even so, Erasure is one of the most useful Quirks to have—especially against someone with a particularly strong Quirk.

7 Half cold, half hot is as versatile as it is powerful

Shoto Todoroki is one of the luckiest people in terms of Quirk manifestation. Instead of receiving just one Quirk from one of his parents, or getting a combination of them, Todoroki received both of his parents' Quirks, separately. Todoroki's Half-Cold Half-Hot gives him the power of both fire and ice. His right side is built to resist and produce immense amounts of ice, while his left side is designed to resist and create enormous flames. Todoroki avoided using his Fire for a while, but has since embraced his full Quirk.

Half-Cold Half-Hot gives Todoroki a lot of attack options. Not only can he fight with either element, but he can also combine his powers into a deadly force. He has the advantage of using either side to regulate his temperature, so he doesn't get too cold or overheat either. Todoroki is also known for using his ice as a shield and a slide for agility. Both sides come in handy during almost any battle, making Half-Cold Half-Hot as versatile as he is powerful.

6 Bloodcurdle interrupts its victims

Bloodcurdle allows The Hero Killer: Stain to paralyze his victims for a period of time after ingesting their blood. The paralysis lasts longer depending on the blood type. Stain initially uses this fearsome Quirk to immobilize Pro Heroes before killing them in the name of purifying the Hero Society. Later, however, Stain becomes a vigilante and fights for the Heroes. Bloodcurdle – like Erasure – seems to be an indispensable tool in battle.

As long as Stain can ingest someone's blood (which seems likely in a fight), he can paralyze them just enough to easily obtain victory. After all, there's a reason why he was able to subdue and dispatch so many Pro Heroes during his attacks. The Heroes are lucky that he eventually sides with them because his Emitter Quirk is one they wouldn't want to face alone.

5 Brainwashing allows Shinso to control minds

Hitoshi Shinso has one of the most literally influential Quirks in the series. His Brainwashing Quirk allows him to control anyone as soon as they respond to him. Many are afraid of this power, but Brainwashing only works if Shinso decides to activate it. Even so, Brainwashing has virtually unlimited potential, as long as his target simply responds to Shinso.

Knowing that people would eventually realize the need to respond to his Quirk, Shinso now uses a voice modulator during battle to mimic the voices of others. This way, he can capture his targets by pretending to be someone else. Brainwashing is a Quirk so powerful that it even unlocks One For All and Midoriya's previous users. It's no wonder Shinso was automatically placed in the General Studies Course without considering how immensely strong his Quirk is.

4 Backtracking is hard to control for Eri

Rewind is an amazing Quirk to be found in a seven-year-old girl, but Eri carries it off with bravery. This incredible Quirk has the power to rewind someone to any point in their life that they have ever experienced. Any moment between the last second and the beginning of their life is fair game when it comes to Rewind. Unfortunately, due to her young age and her captivity at the hands of Overhaul, Eri has yet to fully control her Quirk.

She's been working closely with Aizawa to learn about it, but her emotions play a big part in exercising Rewind's command. Fortunately, Eri is becoming more confident in using her Quirk and even helps Mirio Togata regain his lost Permeation Quirk. Eri still has a long way to go, but there's no denying how powerful her Rewind Quirk is.

3 Explosion suits Bakugo's personality

Katsuki Bakugo is one of the strongest and boldest students in My Hero Academia. This is partially due to his indomitable Quirk, Explosion. The explosion is the result of the combination of Bakugo's parents' Quirks. With his Quirk, Bakugo can create explosions by igniting his nitroglycerin sweat. Over the years, Bakugo has perfected his Quirk so much that he can create a concentrated shot and can also use his Quirk for mobility.

Because of Explosion's power (and his personality), Bakugo is often seen as more of an antagonist than a hero. However, Bakugo has proven his naysayers wrong. Bakugo utilizes Explosion to blind and knock back enemies that would otherwise cause irreparable damage. Explosion isn't the stealthiest Quirk, but it makes up for it with sheer, unbridled power.

2 Decay is the most devastating

Tomura Shigaraki's decline is the most devastating Quirk in My Hero Academia. Anything he touches with his Quirk activated will immediately disintegrate. Now that he has awakened his Quirk, Shigaraki's Decay is spreading, causing things adjacent to something he touches to begin decaying as well.

Decay was tragic before Shigaraki’s Quirk awakened, and now it is utterly desperate. With one touch, Shigaraki decimates the city of Deika. Decay is one of the strongest Emitter Quirks because of the utter destruction it brings. If not used carefully, Decay could bring an end to society as we know it. Unfortunately, this unyielding power is in the hands of a villain. It is up to the Heroes to fight this Quirk to end Shigaraki’s reign of terror.

1 One for all has been passed down through generations

One For All is perhaps one of the strongest Quirks in the My Hero Academia universe. With each successive user, it compiles their current abilities to create a Quirk that is so powerful that it requires extreme training to use it. Furthermore, once it was granted to Izuku Midoriya, it gives him the Quirks of the previous users - essentially turning him into a charitable All For One.

One For All has many mysteries that even All Might is still figuring out. However, even without knowing everything about it, One For All is still incredibly powerful. Users who utilize this Quirk can destroy enemies with single strikes, and Midoriya has learned how to use it to empower his leaps to move in combat. It's no wonder All For One wants this Quirk so much, considering how much raw energy is stored in a single Quirk.
