   Izuku Midoriya Anime expert Nicole Favarelli states that Midoriya is the main character, and at first, he’s a “classic nerdy guy:” “He’s short, skinny, he looks like a child compared to many others, and he has no superpower… But his biggest dream in life is to be a hero, so he tries anyway.” He ends up inheriting the Quirk One for All from All Might, which grants him incredible levels of strength, speed, stamina, and agility.

   • Favarelli adds that Midoriya chose the hero name “Deku” (which refers to someone useless) to reclaim it after Bakugo used it to call him weak.
   • Hero name: One for All Hero: Deku
   • Quirk: One for All
   • Birthday: July 15
   • Height: 5’5” (166 cm)

   Katsuki Bakugo Anime expert Ed Erskine explains that Bakugo is Deku’s rival. Favarelli adds, “He’s really a bully at the beginning. But later on in the show, he’s always the one that follows the rules, always the one that goes to sleep early because he needs to wake up early to study before an exam. So he’s really the kind of guy that takes what he’s doing seriously.” Bakugo’s Quirk is Explosion, which fits his explosive and angry personality.

   Shoto Todoroki Shoto Todoroki starts out as a cold, aloof boy recognized by his half red, half white hair and the burn scar that covers half his face. As his hair suggests, Todoroki has both fire and ice powers thanks to his Quirk. Favarelli explains, “His journey is more of a self-discovery of his own purpose and detaching himself from his father, [who] was already a famous hero, [and] not wanting to follow in the steps of his own dad.”

   • Anime expert Megan Blue adds that Todoroki has “overcome his past abuses and his personal vendettas with his family to become a better person and a hero.”

   Denki Kaminari Denki Kaminari is an energetic boy with blond hair with a black lightning-shaped streak on the side. As you can probably guess from his character design, his Quirk is electricity-based.

Her Quirk also allows her to do anything a frog can; she can extend her tongue 63 ft (20 m) and use it to lift people, and she can stick to walls.

    Hanta Sero At first glance, Hanta Sero looks like an average student… until you realize he has tape dispensers for elbows. His Quirk is literally tape—he shoots out tape from his body and uses it to tie up his opponents or to pull himself to different locations. Hanta is a pretty social and confident student, and he’s not afraid to call his classmates out when they’re acting out.

    • Hero name: Taping Hero: Cellophane
    • Quirk: Tape

    Kyoka Jiro Jiro is a blunt and sarcastic girl most recognized by the permanent earphone jacks that extend from her earlobes. This is thanks to her Quirk, which allows her to plug the jacks into things, channel her heartbeat, and create massive vibrations.

    Mezo Shoji At first glance, Mezo Shoji is a frightening sight to see. He’s tall and muscular, and he has 6 arms. In addition to his extra arms, his Quirk also gives him a set of tentacles, which he can use to replicate other body parts, which in turn enhances his senses. But despite his tough appearance, he’s a gentle, selfless person.

    • Quirk: Dupli-Arms
    • Birthday: February 15
    • Height: 6’2” (187 cm)

    Mashirao Ojiro Mashirao is a hard worker who’s very humble and doesn’t enjoy the spotlight. He’s often described as “plain,” but he’s anything but; he has a large tail that also serves as his Quirk.

    Koji Koda Koda has one of the most unique appearances of all the students in Class 1-A, as his head resembles a rock. Though he looks big and intimidating, he’s actually pretty timid and uses sign language instead of speaking. His Quirk, Anivoice, allows him to communicate with animals, and he seems to enjoy being around them more than people.

    Rikido Sato One of Sato’s most defining features is his large mouth, and it makes sense when you consider his Quirk—for every 10 grams of sugar he eats, his strength increases fivefold for 3 minutes. However, his intelligence decreases until the effects wear off. In his free time, Sato loves baking sweets for his classmates.

    • Hero name: Sweets Hero: Sugarman
    • Quirk: Sugar Rush
    • Birthday: June 19
    • Height: 6’1” (185 cm)

    Toru Hagakure Toru Hagakure is a cheerful and easygoing girl. She loves shopping and anything cutesy, and she’s a romantic at heart. Her Quirk is invisibility, so people usually only know she’s around because her uniform is visible. Her Quirk also allows her to refract light and generate light to blind enemies.

    • Hero name: Stealth Hero: Invisible Girl
    • Quirk: Invisibility
    • Birthday: June 16
    • Height: 5’0” (152 cm)

    Yuga Aoyama Yuga Aoyama is a flamboyant young man who loves attention, even though his classmates often ignore him. Deep down, he’s actually pretty insecure and just wants to make friends. His Quirk, Navel Laser, is pretty much what it sounds like—he can shoot a sparkling laser from his navel.

    • Hero name: Shining Hero: Can’t Stop Twinkling
    • Quirk: Navel Laser
    • Birthday: May 30
    • Height: 5’6” (168 cm)

    Minoru Mineta Mineta is widely considered the least popular character in Class 1-A, and that’s because he’s a total pervert. He’s constantly thinking lewd thoughts and trying to spy on the girls. In fact, trying to get ladies is one of his main reasons for wanting to become a hero. His Quirk, Pop Off, allows him to remove the purple balls from his head and use them as projectiles. Erskine also adds that Mineta “brings comedic timing into the show as well.”

    • Hero name: Fresh-Picked Hero: Grape Juice
    • Quirk: Pop Off
    • Birthday: October 8
    • Height: 3’7” (108 cm)

• Anime & manga expert Cedric Han says there’s a common misconception that the students in Class 1B are weaker than Class 1A. He says they’re equally strong, but the main characters are in Class 1A and Class 1B has more side characters.
