Mirko has, so far, impressed the fans quite a lot. Although she is the Number Five Hero, her display has shown, time and again, that she is extremely underrated and deserves far more credit than she gets. From the Paranormal Liberation War arc, all the way to the final war, she’s proven herself to be a real fighter.

6Incredible Combat Prowess

Mirko is an incredibly skilled combatant. The fact that she places within the top 10 proves thather abilities are beyond the level of average pro Heroes. Her speed allows her to defeat opponents before they even realize that they have lost.

At the same time, Mirko also possesses tremendous physical power, as seen during her displays in the Paranormal Liberation War arc and, more recently, in the Final Arc ofMy Hero Academia. She is exceptionally well-versed in close-quarters combat and has demonstrated this time and again in the story.

5Fought High-End Nomus

Another incredible display of Mirko’s strength came during the Paranormal Liberation War arc, where the Heroes assembled to fight against the Paranormal Liberation Front in an attemptto stop Shigaraki Tomurafrom ascending to the next level. The war saw every Hero launch an incredible offensive against the villains and, unsurprisingly, Mirko was at the head of the army.

She was one of the first people to engage the Villains and was the closest to stopping Shigaraki. At the same time, she was faced with several High-End Nomu, all of which are known to be powerful enough to even take on the likes ofEndeavor, the Number One Hero. Despite that, Mirko was able to take them head-on for extended periods of time and impress the fans with an incredible show of might.

4Fought Shigaraki Tomura

Mirko is certainly not scared of any challenges and, even though she failedto stop Shigaraki’s evolution, she was still able to fight him. This happened during the Final War arc of the series where the leader of the Paranormal Liberation Front was confronted by Heroes once again.

Despite knowing that she wouldn’t be able to defeat him, Mirko was certainly not intimidated by him and took him on with everything that she had. Expectedly, she suffered quite a bit in this fight, however, that wasn’t enough for her to back down. This just goes to show that Mirko is certainly a different breed of Hero.

3Injured Shigaraki Tomura

Not only did Mirko fight against Shigaraki, but she also managed to injure him in combat. As fans saw during the Paranormal Liberation War arc, Shigaraki has incredible durability which has often been compared to that of All Might. As such, he doesn’t take damage easily even against some of the strongest characters, such as Endeavor.

In fact, even when Aizawa was using his Quirk erasure powers on him, his durability was great enough to take some of Endeavor’s strongest attacks. Despite that, Mirko was eventually ableto damage him in the Final War arcwith attacks such as the Luna Rush. Once again, this just goes to show that her abilities are nothing to take lightly. Mirko has always been one of the strongest Heroes in the series and she proves this time and again.

2Indomitable Fighting Spirit

Perhaps one of the greatest qualities of Mirko is that she possesses an indomitable fighting spirit. In the face of the enemy, she is never one to back down or surrender. This was very evident from her assault on the Paranormal Liberation Front where she fought against the many Nomu. Mirko took them all on at once and delivered powerful blows to them.

Thanks to their recovery Quirks, they were able to regenerate and injure Mirko seriously. She ended up losing her left arm and right leg in this fight yet didn’t stop pursuing her target, Shigaraki. Furthermore, in the Final War arc, where she fought Shigaraki, she ended up losing her other arm as well. Despite that, Mirko continued to fight in combat when other Heroes were already exhausted. It was only after she received her serious injuries that she was able to injure Shigaraki, which makes her even more impressive.

1Doesn’t Fear Anyone

Evidently, Mirko is not one to fear any of her opponents. Her personality is quite possibly one of the most comforting of any Hero to have for a person in need of help. Mirko always saves those around her with a smile on her face. Even in the face of the most powerful enemy, she is never scared and always fights with everything that she’s got.

Even if she knows that the enemy is way above her in terms of skill and strength, Mirko doesn’t give up and, more often than not, manages to pull through, one way or another. These qualities of hers certainly make her a very special Hero. Despite being Number Five in Japan, Mirko has won the hearts of the fans way more than some others, such as Edgeshot or Best Jeanist, both of which possess higher rankings. Undoubtedly, Mirko is a very underrated hero.
