~ Izuku steeling himself to beat Overhaul to save Eri.

Izuku Midoriya is the main protagonist of the popular manga and anime series My Hero Academia. His Hero name is Deku and he was originally Quirkless, but after meeting All Might and impressing him with his bravery, he gains One For All, becoming its ninth user.

He is voiced by Daiki Yamashita in the Japanese version of the anime and by Justin Briner in the English version.



He is shown to be loyal to the hero academy and All Might. In the beginning, Izuku felt insecure about not having a quirk and was seen as an outsider to most of the community for lacking a quirk. However, when he was granted his quirk powers by All Might, Izuku was grateful that he would be a powerful hero. He is shown to be friendly and open-minded around others.

Despite being bullied by Katsuki Bakugo, Izuku did not show any negativity for his bullying and still tried to work alongside him.

As a hero, he is shown to be fearless and willing to confront the villains despite going against the rules of the academy such as leading a mission to rescue Katsuki from the League of Villains.

  • When asked by the One For All vestiges if he has the determination to kill Tomura, Izuku remarks on how he felt the pain of a crying child inside Tomura's heart, and in spite of all of the things that Tomura did, Izuku wants to try and save Tomura first and only kill Tomura if absolutely necessary.

  • He's disheartened when he sees that Overhaul still doesn't feel remorse for what he did to Eri and still holds hatred towards him to the point of calling him a "diseased maggot", but he still decides to honor the deal Overhaul made with Lady Nagant to see his boss even after everything he did to Eri and Sir Nighteye.
  • He decides to distance himself from All Might to protect him from any assassins sent by All For One, assuring him he'll be alright.
  • He spends several days without eating or rest traveling across the country, defeating villains and helping people, bearing the burden of fighting All For One, and protecting the fractured hero society all by himself.
  • Hesitates while fighting a villain, Dictator, due to being unwilling to harm the brain-controlled innocent civilians.

  • When he heard from Toru Hagakure that Yuga was the traitor, Izuku accompanied her to find him out of concern. When Yuga fired a laser at him (only to be deflected by Toru's Quirk), he restrained him with Blackwhip, telling him that Toru exposed him to stop him from harming anyone else and offers to take him in so he won't have to be the mole anymore.
  • While some of Class 1-A felt betrayed and angry towards the revelation of Yuga being the traitor, and Yuga himself believed that he was a rotten villain, Izuku reminded him that he still helped Fumikage and Katsuki at the training camp and left the cheese as a secret cry for help, telling him that he shouldn't blame himself since having to obey All For One was beyond his control and nobody should be labelled as a villain for the rest of their lives just for committing crimes. In the end, he offers his hand Yuga to convince him that he can still be a hero.
  • Hugged his mother and bid farewell to Kota and Eri as he left U.A.
  • Thanked Ochaco for defending him in her speech and sympathized with her drive to understand Toga, saying he wants to do the same with Shigaraki.
