The My Hero Academia anime is now on its last arc. We will get to see the fight between One for All vs. All for One, and we know it is going to be epic. Before that, let’s look at the villains who became relatively easy stepping stones toward this journey and gave our heroes experience in battles.

Today, we will be talking about the weakest villains who are well-known in the series and discussing why they made it onto this list. We will start our ranking with the easiest wins to the more challenging ones.

1. Mustard

He is considered a minor threat as he is not immune to his own Quirk. His Quirk allows him to release sleeping gas, which, if he did not wear a mask, would put him to sleep. He is a teenager and joined the Vanguard Action Squad. He is one of the villains who resorted to using guns to gain the upper hand in combat situations.

During the Hero Training Arc, he did some damage, but he was defeated as easily as Itsuka breaking his mask, which led him to fall asleep. He also is very underconfident about himself. We know that he was arrested, but it is unsure if Mustard was sent to Tartarus as he was underage.

2. Lower-Tier Nomu

A Nomu is only as good as its level; a lower-level Nomu is easily defeated by the heroes. Created by Kyudai Garaki, they were classified into different categories. The lower-level ones have no concept of understanding or free will.

They are just built to fight and lack battle sense, too. They were essentially bodyguards for their scientists and powered by giving Quirks to them. A higher-rank Nomu made Pro Heroes fight hard. The only disadvantage was the large number of low-level Nomu, making the battle more about endurance and stamina for the heroes rather than a test of strength.

3. Gecko

Also known as Spinner, Gecko was inspired by Hero Killer: Stain and joined the side of the villains. During the final fight, it is seen that his contribution is not significant. His Quirk was similar to Tsuyu’s frog-like abilities. At most, he could stick to walls and climb. The only Quirks that One for All gave him were what made him a bit of a challenge to fight.

Eventually, his body does not respond well to the Quirks he receives, and he is unable to cope with the fight against Mezou Shoji. Shoji tries to talk to him and turn him around by saying revenge is not the answer, which goes unheard. He is one of the weakest villains in My Hero Academia as his original Quirk was not very battle-efficient, and he eventually loses the fight.

4. Kyudai Garaki

We can give Kyudai Garaki some credit—when it comes to being smart, he sure is something. He is responsible for the creation of Nomu and even called them his children. His Quirk, called Lifeforce, extended his lifespan and gave him a younger look than his true age, which, again, when put into combat, is not a useful skill to have. His intelligence and scientific genius are what makes him scary.

He is a coward and panics when danger is in front of him, chooses not to show his face, and makes the Nomus he created fight for him. All of this makes him one of the weakest My Hero Academia villains.

5. La Brava & Gentle Criminal

One of Midoriya’s easiest battles was with La Brava and Gentle. We see both of them trying to enter U.A. High School during an event. Midoriya found them suspicious and chased after them. Both of them have a somewhat controversial relationship throughout the series. They are super codependent on each other.

During the fight, Midoriya used Full Cowl at 8%, which is a low number, considering how difficult the fights Midoriya had experienced before were. Not only did he help the Hero Association capture them, but he was also able to finish the fight and leave unscathed. He even made it to his performance, where he asked Eri to come and watch. For Midoriya, this felt just like a training session. Also, neither La Brava nor Gentle has any Quirk that would support them during battle. 

6. Tatsuyuki Tokoname

Tatsuyuki Tokoname, also known as Slidin’ Go, started as a Pro Hero but changed sides by joining the Meta Liberation Army and later became the No. 2 adviser in the Vanguard Action Intelligence Regiment: Carmine.

His Quirk allowed him to slide smoothly on any surface, which is a neat ability but not one that would provide an advantage during a battle. His combat abilities were not even recognized in the organization he joined, as he was not put on the front lines to fight. He was simply arrested by Death Arms, a Pro Hero, under orders from Hawks after receiving intel about him being a traitor.

7. Muscular

Goto Imasuji, known as Muscular, had a Quirk called Muscle Augmentation, allowing him to increase his physical abilities. He comes under the weakest My Hero Academia villains as he is defeated by Deku.

He appeared during the raid after joining the League of Villains. Muscular had not followed protocol and engaged in a fight with Deku, in which he had a very twisted way of acknowledging Midoriya’s strength. During their second encounter, Midoriya had powered up exponentially so that Muscular did not stand a chance. He pushed himself so much that his tendons sporadically unraveled. He lost to Deku’s One for All: Full Cowl 100%

8. Kai Chisaki

Overhaul was a former Yakuza and leader of Shie Hassaikai. He played the role of the main antagonist in the Shie Hassaikai Arc. He was among the most ruthless villains, especially in how he treated Eri.

With his Quirk, he was extremely dangerous—that is until he lost his arms. His ideology, if he had succeeded, would have created a world without heroes. Even though he was a notable villain, he became irrelevant during Midoriya vs. Lady Nagant, as Tomura erased his Quirk and stole his product to erase others’ Quirks. By the end of the Dark Hero Arc, he is nothing but a normal criminal, making him one of the weakest villains in the My Hero Academia universe.

9. Lady Nagant

She was introduced as the strongest villain as she was an elite assassin and never missed her shot. She has Rifle and Air Walk as her Quirk. Being an assassin for the Hero Association, she realized that they abused their power and made criminal and corrupt heroes be ‘taken care of’ in a non-legal manner.

We knew she was very powerful and a great shot. In her fight during the Dark Hero Arc with Midoriya, he was able to keep up with her. She finally realized that she was not going to kill him because, somewhere, she did not believe in All for One. She is one of the weakest anime villains, not because of her skills but because there is goodness in her. As a villain, she did not do a good job and eventually joined the Heroes’ side.

10. Hero Killer: Stain

Chizome Akaguro is Hero Killer: Stain. He had a good Quirk called Bloodcurdling, which would paralyze the opponent. It looked like a very powerful attack to have, and he did end up taking out a lot of Pro Heroes because he wanted to eradicate False Heroes.

During the fight, when Midoriya was fighting with him to save Tenya and Native, who were both paralyzed by him, he went to Full Cowl at 5%. He managed to do some damage, but by then, Stain had paralyzed him too. Shoto enters the scene, and after some time, Izuku realizes that his ability to paralyze is effective depending on the victim’s blood type.

From that moment, all three of them fight their best and end up winning against him. They tie him up, and by that time, other Pro Heroes arrive to take over. So, his weakness was caught, his Quirk was not scary anymore, and three students were able to defeat him.

Conclusion 

My Hero Academia has introduced villains of all levels, from terrifyingly powerful foes to those who serve as mere stepping stones in the heroes’ journey. While some villains posed serious threats, others were defeated with relative ease. However, every battle in the series, no matter how short or one-sided, played a crucial role in shaping our protagonists, especially Midoriya.

One of the key takeaways from My Hero Academia is that not all villains are inherently evil, and not all heroes are truly good. Characters like Lady Nagant and Gentle Criminal remind us that circumstances and ideologies play a huge role in defining “villainy.” At the same time, those who embrace true evil, like All For One, make it clear why some threats must be eradicated.

Despite the heroes easily defeating some of these villains, the writers crafted each fight with care, complementing the anime’s dynamic art style and well-choreographed action. Even the weakest villains contributed to the overall growth of the heroes, ensuring that every battle, no matter how small, had a lasting impact.
