~ Izuku Midoriya


In a world where most humans on the planet develop superpowers soon after they're born, a boy named Izuku Midoriya was one of the few who never developed any powers. As a child, Izuku dreamed to become a superhero like his idol, All Might, after he developed his power, or "Quirk". As such, he was devastated once he learned that he'd never get a quirk. His lack of a Quirk made him a prime target for bullying, but Izuku still wanted to be a hero, and planned to go to the prestigious U.A. hero academy. Ten months before the entrance exams for U.A. started, Izuku came face to face with All Might after he was saved from a villain by him. Izuku asked All Might if it was possible for someone without a quirk to be a hero, but he responded by telling him that he needed realistic dreams. Soon after, the same villain from before ended up breaking free and attacking one of Izuku classmates. Despite not having a quirk, Izuku still tried to save his classmate. While he didn't stop the villain, he did give All Might enough time to defeat them himself. After this, All Might decided that Izuku had the potential to become a hero, with his help. He decided that he would grant Izuku his own Quirk to help him achieve his dreams. After ten months of training, All Might passed his Quirk, One For All, down to Izuku. Izuku then managed to pass the entrance exam, and officially enrolled in U.A, taking on the Hero name "Deku".

Powers & Abilities

  • One For All: Izuku's 1st Quirk, which was passed down to him by All Might. A combination of a Quirk that can be passed down to others and a Quirk that stockpiles power, One For All grants Deku the ability to access the stockpiled energy, momentarily increasing his strength and speed to superhuman levels. By focusing One For All in one of his limbs, Deku can unleash explosive attacks powerful enough to release giant gusts of wind pressure and break apart massive structures, or jump several stories into the air with ease. Unfortunately, using One For All like this will usually break whatever body part it's used in, and overuse of it has led to Izuku's hand being permanently disfigured. However, Deku is capable of focusing One For All's power to a lesser degree and avoid injuring himself, though he can only access about 20% of his full power by doing this.
    • Detroit Smash: A punch enhanced by One For All. The air pressure from this attack was strong enough to shatter multiple windows and break through several floors of the building above him.
    • Delaware Smash: By enhancing his fingers with One For All and flicking, Izuku can fire powerful blasts of wind pressure from his hands. These blasts are powerful enough to cause vortexes in water and shatter giant structures of ice. He's even shown the capability to use this with already-broken fingers, at the cost of disfiguring his right hand.
  • Blackwhip: Deku's 2nd Quirk, which was originally wielded by Daigoro Banjo, Hero Name: Lariat, which also was a previous user of One For All, until Deku inherited it. It allows him to manifest tendrils of dark energy from his arms, which are useful for grabbing nearby objects or swinging around the environment. The dark energy came out from his body in the shape of ropes.
  • Float: Deku's 3rd Quirk, which was originally wielded by All Might's master, Shimura Nana until Deku inherited it. It allows him to levitate and suspend himself in mid-air.
  • Danger Sense: Deku's 4th quirk, which was originally wielded by Hikage Shinomori until Deku inherited it. It allows him to sense danger of any sorts via a painful stabbing sensation in his head. Comparable to Spider-Man's senses.
  • Smokescreen: Deku's 5th quirk, which was originally wielded by En until Deku inherited it. It alows him to generate large amounts of smoke in an area to obscure the vision of his opponents and catch them by surprise.
  • Fa Jin: Deku's 6th quirk, which was originally wielded by the Third User of One For All until Deku inherited it. It allows the user to build up kinetic energy through repeated movements for later use. Once the user chooses to release that energy it will grant the user an explosive burst of speed and power. The user can choose to only use some of the stored up energy at a time, allowing them to achieve multiple bursts of speed and power.


  • Costume Gamma: After deciding to make his fighting style more kick-based to lower the damage to his arms, Izuku had some modifications made to his Hero Costume. The new additions consist of arm braces to shield his arms, upgraded gloves that focus the wind pressure from Deku's attacks into long-ranged blasts, and iron boot soles to increase the power of his kicks.

Alternate Forms

  • One For All: Full Cowl: In order to prevent breaking his bones when he uses One For All, Izuku created this technique. By channeling a fraction of One For All's power and transferring it through his entire body, Izuku can empower his whole body. This grants him a boost in strength, speed, agility, and mobility, letting him scale buildings and make long leaps with ease. It also prevents Deku from injuring himself by evenly channeling power throughout his body. As of now, he can use at least 5% of One For All's power safely, though he's gone up to 20% before. However, due to only utilizing a portion of One For All's power, his attacks in Full Cowl don't possess the incredible destructive force of his normal attacks.
    • 5% Detroit Smash: A punch enhanced by One For All: Full Cowl.
    • Delaware Smash Air Force: Using the upgraded gloves of his Costume Gamma, Izuku fires a more compressed and focused version of his Delaware Smash that doesn't break his finger when used. The attack had enough concussive force to stun the villain Gentle with one hit. By using all five fingers on his hand, Deku can fire up to four shots at the same time.
    • One For All: Full Cowl - Shoot Style: A variation of Full Cowl that only affects Izuku's torso and legs. By concentrating the flow of power into only two areas, Izuku's legs gain a much larger boost than when he uses Full Cowl on his whole body. Izuku developed this technique to compensate for the damage his arms were taking when he fought, letting him utilize a kick-based fighting style that allowed for more range and power.
      • Shoot Style: St. Louis Smash: Deku leaps into the air before landing a roundhouse kick to the opponent's face.
      • St. Louis Smash Air Force: Using 45% of One For All's power Deku arches his leg back and performs a strong vertical roundhouse kick, firing a large blast of compressed air.
    • One For All: Full Cowl - 20%: In moments of extreme desperation, Deku can access 20% of One For All's power and channel it freely through his body, granting him a boost to his strength, speed, and agility even larger than Full Cowl without injuring himself. Using One For All 20% puts a lot of strain on Deku's body, to the point where he feels like his bones are about to break, and he can only use it safely in brief moments.
      • Manchester Smash: Using 20% of One For All's power, Deku leaps at his target and hits them with a downward axe kick capable of instantly pulverizing the ground.
    • One For All: Full Cowl - 100%: Deku lets the full extent of One For All's power flow freely through his body, granting him a tremendous boost to strength and speed that let him easily overwhelm the villain Overhaul. He can only use it without destroying his body in the process when in contact with Eri, who's rewinding Quirk cancels out the damage he does to himself.
  • One For All 100%: A rare state that allows Izuku to access to one hundred percent of One For All's power, granting him strength on the level of All Might. However, using this will basically destroy whatever limb he channels the power into.
    • 100% Detroit Smash: A punch enhanced by One For All 100%, which can send someone flying into a cliff hard enough to partially shatter it.
    • 1,000,000% Delaware Detroit Smash: Activating One For All 100% during an adrenaline rush to go even further beyond one hundred percent of its power, Deku does a point-blank Delaware Smash, followed up with a full-force Detroit Smash. This attack was enough to overpower Muscular's Quirk and incapacitate him.
    • Wyoming Smash: Drawing out 100% of his powers into his arms, Deku proceeds to spike his opponent's head, creating a powerful shockwave.
    • Texas Smash: Deku uses this move against Shigaraki duing the Paranormal Liberation War. It is likely the same technique as All Might's.
  • One For All Faux 100%: Deku draws out 45% of One For All's power, and combines it with the stored kinetic energy generated by Fa Jin. By doing this he is able to draw out the blinding speed of using One For All at 100%, without the recoil that comes with it.
    • Faux 100% Manchester Smash: Deku delivers a Manchester Smash using Fa Jin. He lands an axe kick on to his opponent at blinding speed.
