The Pro Heroes (プロヒーロー, Puro Hīrō) are those who are licensed to use their Quirks to protect the civilians and save the world from the villains, natural disasters, or any other kind of harm. The overall hero activity is managed by the World Heroes Association.

To become a Pro Hero, the students in U.A. High School must work as interns through Hero Agencies. The students can also take part in Hero-Work Studies under the guidance of a Pro Hero, and the permission to fight the villains in emergency situations, by passing the exam for the Provisional Hero License.

In the aftermath of the Paranormal Liberation War, many Pro Heroes have retired or quit due to the massive destruction left by Gigantomachia's rampage and the prison breakouts by All For One's escape from Tartarus, causing them to receive excessive criticism from the public especially where they were vandalized by the anti-hero protestors.
Enji Todoroki (轟 炎司, Todoroki Enji) / Endeavor (エンデヴァー, Endevā) Voiced by: Tetsu Inada (Japanese); Patrick Seitz (English)

Enji Todoroki is a hotheaded and stern hero whose Quirk Hellflame (ヘルフレイム, Heru Fureimu) gives him powerful pyrokinetic abilities. He himself is immune to flames and can easily control the shape and temperature of a blaze. As a Pro Hero, Enji is depicted as confident, reliable, and imposing, thanks to his excellent track record of solving cases. His rude and aggressive personality is well-known to the public, with his fans thinking of that as a selling point while others are scared by his overall violent attitude. His obsessive drive to surpass All Might in terms of strength and power has followed Enji throughout his entire life, with repeated failures having plagued him since his youth. Dedicated to his studies and hero work, Enji strives to become the absolute strongest Pro Hero in the country, but the figure of All Might proved itself too much of an insurmountable obstacle for him or anyone else to overcome, leaving Enji in a growing state of despair as he becomes more and more aware of the impossibility closing the gap between him and the Symbol of Peace. Even though he dislikes his longtime rival All Might, Enji still respects his power and feats as the No. 1 Hero, to the point of not believing that the "real" All Might was a sick and weak-looking man. Enji is the husband of Rei Himura and the father of Shoto and his three older siblings. Enji has a strained relationship with his wife and children due to having projected his obsession of surpassing All Might on them, particularly on his sons Toya and Shoto. However, after becoming Japan's No. 1 hero following All Might's forced retirement, Enji starts to realize his mistakes and resolves to make amends to his family. During the series epilogue, Enji is confined to a wheelchair as a result of his injuries from the war, forcing him to retire and focusing on a new goal of making amends for his own past misdeeds against his family, which includes regularly visiting Toya at the prison.

After the League wins their war with the Meta Liberation Army, Tomura merges both organizations to form the Paranormal Liberation Front.

Tenko Shimura (志村 転弧, Shimura Tenko) / Tomura Shigaraki (死柄木 弔, Shigaraki Tomura) Voiced by: Kōki Uchiyama, Arisa Sekine (young) (Japanese); Eric Vale, Emily Fajardo (young) (English)

The main antagonist of the series and All For One's apprentice. Born the grandson of All Might's master Nana Shimura, as a child he was rescued from the streets by All For One after he accidentally slaughtered his entire family with his Quirk Decay (衰替/腐らす/腐れる/朽ち果てる/朽ちる/衰える/腐る/濫費/乱費/凋落/凋尽/萎靡/漸減/衰勢/荒廃/衰退/腐敗/減衰/崩壊/ディケイ/デカダンス, Suitai/Kusarasu/Kusareru/Kuchihateru/Kuchiru/Otoroeru/Kusaru/Ranpi/Ranpi/…

Shigaraki (死柄木) / All For One (オール・フォー・ワン, Ōru Fō Wan) Voiced by: Akio Ōtsuka, Hiroshi Kamiya (young) (Japanese); John Swasey, Ryan Negrón (young) (English) All Might's arch-enemy and once the world's most powerful supervillain, also known as the Symbol of Evil (悪の象徴, Aku no Shōchō). His Quirk All For One (オール・フォー・ワン, Ōru Fō Wan) enables him to both steal and bestow Quirks, as well as wield multiple Quirks at once. He is also obsessed with stealing One For All because it is the only Quirk that can successfully defy him. The character was inspired by the Star Wars antagonist Darth Vader and the X-Men villain Cassandra Nova. All For One is a subtle, sadistic, and malevolent man, who likes to rule from the shadows and enjoys himself at the expense of others. In the past, he looked after his younger brother Yoichi, although he was condescending towards him. He mocked his frail brother for harbouring ideals of justice. He has a firm contempt for ideals of morality and justice, dismissing them as beliefs that shackle personal freedom. All For One is a patient mentor of his protégé, Tomura. He gives constructive criticism and encouragement to his successor. He also prefers to teach Tomura by giving him varied experiences that he can learn from. However, this apparent benevolence is a façade, because All For One views Tomura merely as a valuable tool with which to steal One For All. Although he is initially defeated by All Might and imprisoned in Tartarus for his crimes, it is revealed that All For One arranged for his original Quirk to be transplanted into Tomura. All For One eventually escapes when Tomura and Garaki's surviving Nomus launch an assault on the prison and free all of its inmates. Acquiring a drug that Kyudai reverse-engineered from Overhaul's Quirk-Destroying Drug to function like Eri's Quirk and warned that it would eventually revert him into nothingness, All For One uses it on himself during the final battle to fight at his prime while adamant that his visage within Tomura would see him through to the end. But All For One senses his visage destroyed by Tomura and makes his way towards his ward to regain control of him. During the final battle, All For One becomes emotionally unstable due to the side effects of the drug, which made him lose control of his Quirk factors, and eventually is defeated by Katsuki Bakugo. With the drug ac…

The primary rival of U.A. High School, Shiketsu High School (士傑 高校, Shiketsu Kōkō) is regarded as the top hero school in West Japan. Shiketsu has very strict regulations compared to those of U.A. and has a more militaristic environment. During the Dark Hero Arc, it is revealed that Shiketsu allied itself with U.A. to help provide security; and it also established a protocol in light of the events caused by Himiko Toga.

Inasa Yoarashi (夜嵐 イナサ, Yoarashi Inasa) / Gale Force (レップウ, Reppu) Voiced by: Ryota Iwasaki (Japanese); Matt Shipman (English)

A first-year student whose Quirk Whirlwind (旋風, Senpū) allows him to control the wind. He was the top-recommended student for U.A. High School but he withdrew his application. Inasa is a hyperactive and enthusiastic young man who expresses himself with vigor. He is loud and can come off as obnoxious, but he is oddly polite and speaks very formally most of the time. Inasa claims that there is almost nothing that he dislikes, and growing up as a kid he enjoyed everything, even bugs. He has a habit of approaching strangers to try and make friends with them. Sometimes, he becomes so excited that he will start talking emphatically about being passionate, and the person or people he's talking to tends to get confused. He developed a rivalry with Todoroki, at first, which arose from a moment in his childhood where Endeavor denied him an autograph. However, he is shown to have apologized to Shoto after the Provisional Hero License Exam, despite admitting that he still hated him. Inasa was truly sincere, showing that his hatred of Shoto had at least diminished. In the Remedial Course Arc, the relationship between the two appears to have improved quite a bit, although their differing personalities and tastes still clash every so often.

Camie Utsushimi (現見 ケミィ, Utsushimi Kemii) / Maboromicamie (マボロミカミィ, Maboromikamii) Voiced by: Minori Chihara (Japanese); Brittney Karbowski (English)

A second-year student whose Quirk Glamour (蠱惑/哀れ/優れ/色気/魅力/幻惑/グラマー, Kowaku/Aware/Sugure/Iroke/Miryoku/Genwaku/Guramā) allows her to create illusions that form from a mist-like substance that she emits from her mouth. Camie is perceived as less serious than most of her Shiketsu peers, easily brushing off that she has been targeted by the League of Villains who impersonated her to infiltrate the Provisional Hero License Exam. Seiji Shishikura believes that she is an utter fool, but their teacher describes her as simply being bubbly. She is very laid back, straightforward, and tends to be quite talkative. While she appears to be naïve to a fault, in hindsight Camie is seen as rather clever. During the remedial course, she came up with the idea of the remedial students using their Quirks to impress the children rather than fighting violence with violence. She is also truthful and to a point, insightful, telling Katsuki Bakugo that he does well when putting his loud and aggressive attitude aside.
