Quirks are unique abilities in My Hero Academia that grant the user superhuman powers. Some are incredibly useful—particularly in combat—while others don't do much of anything. Many characters born with these traits use their powers for the greater good, while others have their eyes set on achieving evil deeds.
While most of the heroes in My Hero Academia possess excellent Quirks, there are also plenty of villains who have great ones themselves. These ten villains have some of the best in the series; even though a few of them aren't that powerful, they are practical in nature one way or another.
Warp Gate (Kurogiri)
Touma Shigaraki's right-hand man, Kurogiri, possesses an artificial Quirk called Warp Gate. It allows him to create portals that come in the form of dark fog. Anything or anyone that comes into contact with this portal is instantly transported to another location, and anyone caught in the portal when it closes could even be cut in half.
While it's not a Quirk best suited for fighting, it's very handy for the villains when it comes to teleporting and making getaways. But, for the portals to activate, Kurogiri's real body must be present.
Compress (Mr. Compress)
Atsuhiro Sako is otherwise known as the calculating MHA villain Mr. Compress, and his Quirk, though odd, is undeniably useful. Compress gives him the ability to shrink anything down to size into the form of a small marble. All he has to do is simply touch any object or person with his hand.
Thanks to this Quirk, Mr. Compress can carry large objects around in the form of marbles. Whenever he wants to end a fight on short notice, he can just compress his opponents and abduct them afterward.
Cremation (Dabi)
Dabi has a fire-based Quirk, Cremation, that lets him fire blue flames from his body. These flames are hotter than the ones from Endeavor's Hellflame—so much that they burned down a forest and incinerated an entire group of villains. The temperature of the flames depends on how much rage Dabi is feeling.
Using too much of the Cremation Quirk can be hazardous to Dabi, however. His skin can burn from the blue flames, and his body can also become numb. Should he lose his temper, the blue flames will go completely berserk.
Bloodcurdle (Stain)
Stain's Quirk, Bloodcurdle, is one of the more unique Quirks in My Hero Academia. With it, he can easily paralyze his foes just by simply drinking their blood, no matter the amount. It's very handy against a group, as he can subdue multiple opponents at once.
How long a victim remains paralyzed usually depends on what blood type they have. Blood type B has the longest time of paralysis, whereas O has the shortest. Stain has no way of determining a victim's blood type, and finding a way to steal blood from his foes can be a hassle in itself.
Double (Twice)
Twice has a Quirk called Double that allows him to create replicas of anyone he comes in contact with. These replicas have the same personality and ability as the person they replicated. Twice can only make two replicas at a time, but he can create an unlimited amount since he can clone himself—and so can his clones.
For Double to work, Twice requires the accurate measurements and exact physical features of whoever he's copying. Otherwise, his replicas would last for a short duration before dissolving. Any physical change to the original person would require another measurement for Twice to conduct.
Transform (Himiko Toga)
Himiko Toga's Transform Quirk is pretty much straightforward; she can transform into the appearance of any person, provided that she drinks some of their blood. She can become a perfect replica of anyone whose blood she drinks while also acquiring the voice that person has.
How long Himoka stays transformed depends on how much blood she has consumed. Transform isn't useful for offensive measures, but it's very useful when it comes to espionage missions. In the Quirk's awakened state, Himoka can effectively copy the Quirk of anyone she transforms into.
Weather Manipulation (Nine)
Nine is the main villain of My Hero Academia: Heroes Rising, possessing many different, powerful Quirks, but the Quirk that he was born with, Weather Manipulation, is a very powerful one.
Just as the name implies, Weather Manipulation allows Nine to summon all sorts of weather conditions such as lightning storms and tornadoes. He is more than capable of forming storm clouds and bringing forth strong winds. But, with such a strong Quirk, it comes with major downsides. Weather Manipulation can cause severe pain and cellular degeneration, which nearly brought Nine to the brink of death.
Overhaul (Kai Chisaki)
Yakuza leader Kai Chisaki has a Quirk that, in many ways, works similar to Tomura Shigaraki's. Overhaul allows him to disassemble and reassemble matter with only his bare hands. He can fuse into other people with this quirk or cure his allies' wounds.
As powerful as the Overhaul quirk is, it does have its downsides. Like many other quirks, his relies on physical contact to work. Additionally, overhaul requiring a brief cool-down period for matter construction doesn't help.
Decay (Tomura Shigaraki)
Touma Shigaraki's Quirk, Decay, is one of the more destructive Quirks out there. With just the touch of his hand, he can disintegrate anything he touches. For instance, Shigaraki was able to destroy a house after the Quirk was manifested on him.
Decay can even kill other people, causing their flesh to rot away. Originally, slow, the disintegration process of Decay is, during the events of the series, very fast, and it can spread quickly through the victim's body if the affected body part isn't amputated. While it is destructive, Decay can only work on solid objects, and, like Overhaul, it also requires hands to be activated.
All For One (All For One)
Given that he's MHA's main villain, it only makes sense that All For One has the best Quirk among the villains. His Quirk grants him the ability to steal Quirks from just about anyone. He can even create new Quirks or give stolen Quirks his lackeys.
All For One doesn't necessarily steal every Quirk he sees; he only goes after ones that are simple in nature. Additionally, he has a limit to how many Quirks he can steal, as having too many under his possession can lead to some major consequences.
