Izuku Midoriya

Izuku is a somewhat short young man with a round face, fluffy dark‑green hair, and large green eyes. He has four freckles in diamond formations on his cheeks and is often described as “plain‑looking”.

In Aldera Junior High, he wore a black gakuran with yellow buttons and bright red high‑top boots. After training with All Might, he gained toned muscles.

At U.A., he wears a light gray blazer with turquoise trimmings, white shirt, blue‑green pants, a loose red tie, and his signature red shoes. His right arm has scars from fights with Todoroki and Muscular; he wears a black compression sleeve to support it.

His hero costumes:

Alpha: light green jumpsuit with white outlines, red belt, black pads, white gloves, red boots, mask with ear‑like protrusions, and a translucent respirator (damaged after fight with Bakugo).

Beta: darker teal with black outlines, beige shoulder pads, extended knee pads, beige gloves with blue stripes, metal respirator.

Gamma: Beta with black iron soles on boots, arm braces, wrist straps, yellow bolts.

Delta: Beta with support gloves (white, green palms, yellow sights) for long‑range attacks.

Epsilon: post‑Paranormal Liberation War — damaged look, Gran Torino’s cape, dark red Mid‑Gauntlets, frequent mask/respirator use (shadows eyes, shows only irises).

Zeta: rebuilt Epsilon with Air Force Gloves, red Mid‑Gauntlets (golden stripe), cleaned cape as scarf, darker green, gold outlines, dark green kneepads, fourth belt pouch, no cowl.

Origin: post‑final battle — bandages on wrist/arm, light blue All Might shirt before final fight.

Eta: post‑war — similar to Zeta, repaired cowl/respirator, fixed Air Force Gloves, grayish‑blue protective wrappings with elbow pads, no Iron Soles or cape.

After the final battle with Tomura:

loses arms (regenerated via Eri’s Rewind);

gains scars on head and cheek, heavily scarred hands;

shaves hair to undercut (later returns to original style).

Eight years later, Izuku is taller and teaches at U.A. He wears a black suit, white shirt, green tie, and brown shoes.

He later receives a tech‑based costume (funded by Class A, gifted by All Might): resembles Zeta but mechanical — yellow nano‑machine cape (like Gran Torino’s), jet leg armor, red/yellow boots (like Iron Soles), gauntlets (like Shoot Style Gloves), green/orange stripes, folds into armored briefcase (#18 — his student seat number).

Izuku is a very timid, reserved, and polite boy, frequently overreacting to abnormal situations with exaggerated expressions. Due to yeаrs of being looked down on by Katsuki for lacking a Quirk, he is initially portrayed as insecure, tearful, vulnerable, and non-expressive. These traits are especially present around Katsuki, who also constantly harangued him for his aspirations to become a hero. However, after being accepted into U.A., making new friends, and facing Katsuki during the Battle Trial Arc, Izuku gradually matures into a more confident and braver person who’s always eager to prove his worth as a hero, eventually developing strong leadership skills, which combined with his passion and strategic abilities, have turned him into a central figure within Class 1-A alongside Katsuki.
Izuku is a quite diligent and strong‑willed student, being extremely (and sometimes scarily) enthusiastic about topics related to heroes. His dream drives him to write down notes about everything he learns about heroes’ Quirks and fighting capabilities. Thanks to this practice, Izuku has developed a great analytical mind and can form complex battle plans in a few seconds, factoring in the best ways he can utilize the Quirks of allies and enemies alike for his own advantage.

Izuku externalizes his observations through endless mumbling, a habit that annoys or creeps out his peers. Izuku often writes down his observations in a variety of notebooks he titles as Hero Analysis for the Future; he checks on them regularly during school activities, during his free time, or at night.
Izuku is caring and emotional, never hesitating to help or rescue someone in danger, even if he knows that he might not be strong or otherwise qualified enough to do it. Often, he does this on instinct, taking a more careless approach than the usual overthinking he goes through and putting himself in peril in order to protect someone. All Might claims that this trait gives Izuku the most important natural and innate instinct to be a hero; the pure and genuine desire to help people. However, Izuku putting others’ lives above his own can go to the extreme, to the point where he has little to no sense of self‑preservation. Katsuki speculates that the bullying Izuku received for being Quirkless made him internalize that his life has less worth. Izuku will routinely break his arms for the sake of others, even if it’s not completely necessary, such as demanding Shoto to unlock his full potential by using his fire side. This can make Izuku somewhat short‑sighted, as he continued to break his arms, despite warnings he could permanently paralyze them and cut his hero career short. Eventually, Izuku relented, adapting his battle style to put less strain on his body. Though when he’s in a particularly tight situation, he’ll pull back on old habits.

Izuku is known to help or lecture people with personal and emotional problems, regardless of if it’s his business or not, claiming that a hero should meddle in other people’s lives. This audacious spirit, while initially viewed as perplexing or even insane by others, is also recognized by many, and has earned him the loyalty, gratitude and respect of characters that were previously antagonistic towards him such as Tenya Ida, Shoto, Hitoshi Shinso, Kota Izumi, Sir Nighteye and even the likes of the Hero Killer: Stain and Lady Nagant.

He has a strong fascination with heroes and is shown well‑versed in their history, sometimes even surprising the heroes themselves with his vast knowledge of their abilities and past exploits. He is prone to geeking out and rambling on about the heroes he meets, often bringing up their history and accomplishments, while also being eager to share this knowledge with others. Of all heroes, the Symbol of Peace, All Might, has impacted and modeled Izuku’s life the most. Many of Izuku’s decisions and actions result from his desire to become a Pro Hero similar to All Might, and thus he has a great devotion to him.
Izuku is an avid collector of All Might merchandise, has knowledge of his numerous feats of heroism (no matter how minor), and emulates many of his traits. Having inherited his Quirk, one of Izuku’s current priorities is to be able to live up to his idol’s legacy, as he is always looking for ways to improve his usage of One For All, being aware of the immense pressure that comes with succeeding the Symbol Of Peace. The unwavering trust and approval Izuku receives from All Might has been vital to his development as a hero, especially when the aforementioned feelings of self‑doubt and unworthiness plague his mind.

Izuku appears to have a more brash and abrasive side to him, which typically shows up when he finds himself in combat. This side of him makes him act more like Katsuki, being rather loud and unwavering, and also with a strong drive towards victory. He claims that this is because he sees Katsuki as the embodiment of what someone who strives for victory should be. He has also admitted that he doesn’t like this side of him very much and tends to keep it in check. He does, however, find himself giving in to this almost feral rage when in dire situations and faced against opponents who had brutally hurt people he cares for, like in his battles against Overhaul and Tomura.
Izuku also possesses an empathetic side and has developed a desire to want to understand the Villains he has faced, and potentially save them from themselves. While initially believing Tomura to be a madman who just wants to meaninglessly hurt others, after learning about his tragic history and sensing the pain in his heart through their connection between One For All and All For One, this re‑invigorates his belief that a great Hero is someone who saves others, not kills, and because of this, desires to learn how they became villains and see if there is any way to prevent a fight, though he does concede he very well may have to kill Tomura. While he is not naïve in this ideology and will resort to violence if there is no other option, like during his second fight with Muscular, he truly wishes to reach out and help villains recover and reform themselves, even giving Kai Chisaki (whom he was still bitter towards) the chance to save his boss should he make amends with Eri. At the same time, Izuku desires to save Tomura from his life of villainy and pain, even when such a notion feels unlikely and is deemed pretentious by others, showcasing his great sense of humanity.
Following the conclusion of the Paranormal Liberation War, Izuku had begun to drastically change his behavior. After suffering from the trauma brought on by the War, seeing countless innocent people have their lives ruined by the current state of society, having All For One relentlessly target him for his Quirk, and bearing the responsibility of protecting his friends, Izuku became more cold and distant towards others. When All For One vowed to break him both physically and mentally, he became increasingly paranoid about how much harm he will bring to those who are around him. The overwhelming stress and burden resulted in him rushing into fights and leaving behind All Might and the other Heroes looking after him so that no one else will get hurt. His disregard for his own well‑being becomes the worst it ever has been as well, neglecting to look after his basic needs like sleeping and eating. Katsuki has noted this behavior to be very similar to how All Might was when he was the Symbol of Peace. This increasingly driven, serious side of him has even caused civilians to note that he doesn’t look like a hero. After his friends from U.A. get through to him and take him back in, these traits seem to have diminished, with him now being determined in stopping All For One alongside his friends, teachers, and allies.

During the Final War, even after witnessing Katsuki’s near demise at the hands of Tomura, Izuku maintains his desire to find a way to save his enemy. In the core of One For All, Kudo recognizes that Izuku’s drive to save people is through his belief that everyone possesses an innately human heart, motivating him forward despite suffering grave injuries during his battle against the overwhelmingly powerful Tomura. Once again, Izuku becomes willing to sacrifice One For All as a means of reaching Tomura’s origin and finding the source of his pain and hatred, though this would be interrupted by the untimely return of All For One’s vestige who seized back control of Tomura’s body. With his friends by his side however, Izuku manages to triumph over the Demon Lord, even seeing through All For One’s evil persona and recognizing him as the sad and lonely man that he really was deep underneath.
During the war’s aftermath, Izuku still holds some regret that he couldn’t save Tomura from dying, but was assured by All Might that he managed to save Tomura’s soul by vanquishing his pain and that he managed to complete the duty of One For All. After being rendered Quirkless again with only the leftover embers of One For All remaining, Izuku tries to put on a brave front but is visibly distraught over his time as a hero seemingly running out. He’s also rather muted when attending U.A. as a second year a week later, and doleful but accepting of Yuga’s decision to leave U.A. and start his hero education over. When he tries to strike up a conversation with Ochaco only for her to deflect by commenting on his hair, he also appears concerned for her while uncertain of how to speak with her further.
Izuku also chooses to visit Spinner at Central Hospital to deliver him Tomura’s final words; that he fought to the bitter end in order to destroy. Izuku was undeterred when Spinner labelled him as a murderer, only wanting to carry out Tomura’s final request, and kept his composure when Spinner grabbed him after activating his Body Bulk Quirk, even stopping the doctor from having the villain restrained. Out of compassion, Izuku tells Spinner that Tomura still cared about him and the rest of the League, and at the end of the visit, he assured Spinner that he would never forget about Tomura.

Much later, sensing that Ochaco was hiding something, he goes to comfort her, thanking Ochaco for always helping him and calling her his hero. When Ochaco breaks down and mourns over Himiko’s sacrifice, Izuku shares his own guilt over causing Tomura’s death, but states that even when times seem unbearable, going above and beyond to reach out and offer help will make a difference. Following this, Izuku accepts that he completed the purpose of One For All, a power meant to help others, and resumes his daily life with his classmates.

Eight years pass and Izuku continues his studies at U.A. while documenting his story and experiences in his notebook, reflecting over how his dream of becoming a hero came true even when it seemed impossible, and that everyone around him became a hero by giving him their hopes, prayers, and encouragement to succeed. Eventually, the embers of One For All fade away and Izuku accepts becoming Quirkless again as he goes on to become a teacher at U.A. High School, admitting that while he misses being a hero, he is content with using his experience to help and encourage others.

Izuku has also retained some of his old traits, such as his selfless need to help other people and his mumbling habit, as seen when he flung himself to the ground to save a boy from falling and encounters Dai, telling the middle school student that he can become a hero with his will to help others, even when he possesses an underpowered Quirk. While Izuku was hesitant to accept a mechanized suit as a gift from All Might and Class A, the former Symbol of Peace recognized that Izuku still has the heart of a hero and told him that he had earned it fair and square, causing Izuku to tear up and rejoice as he joins his friends and former classmates, becoming a hero once again.
While being driven by Katsuki and accompanied by Eijiro Kirishima to Class A’s reunion party a month later, Izuku reveals that he still intends to carry on teaching while doing hero work and collecting data on his suit, saying that he thinks he would have started teaching even if he kept One For All, as he enjoys sharing his knowledge with others.

However, having lived his life consistently putting others before himself, with little to no regard for his own well‑being and personal happiness, Izuku was told by Katsuki to think more highly of himself, being further warned that giving everyone special treatment meant that no one is truly special to him. During Class A’s dinner party, Izuku listens on as his friends discuss the topic of heroes now having more free time to spend pursuing hobbies and desires outside of heroism, such as dating, and, in Shoto’s case, bowl and chopstick making classes. Left in deep thought, Izuku contemplates on whether he too wanted more out of his own life despite considering himself to already be “blessed enough”, ultimately leading him to fully realize his feelings for Ochaco.

Following through on Katsuki’s earlier advice, Izuku later finds Ochaco to openly confess his feelings, now wanting to spend more time together with her going forward, and is left overjoyed upon learning that their feelings for one another are mutual, as the two happily take each other’s hand to mark the start of a new relationship.
Shortly upon his return to hero work, Izuku would go on to achieve tremendous feats and is welcomed back to the hero world at large with thunderous applause by everyone who remembers him, being officially called the One For All Hero: Deku, and even skyrocketing up to the rank of No. 4 Hero in Japan.

Overall Abilities: Izuku's greatest asset prior to receiving his Quirk was his vast knowledge of fundamental hero skills and tactics. Izuku studied Pro Heroes for years and is able to apply that knowledge during crisis situations in a practical manner. His immense bravery and desire to become a hero were also important factors in giving him the mentality to protect others. Before gaining his Quirk from All Might, he took on the Sludge Villain and rescued Katsuki because of his boldness and application of heroic skills, something that deeply impressed the No. 1 Hero.

Upon training with All Might, Izuku inherited One For All from him and was granted the ability to harness a stockpile of powerful energy. He can move faster than the eye can see and take down an enormous Villain Bot in a single punch, but the physical backlash at the time prevented Izuku from being able to fight properly or compete with his peers on an even playing field, as throwing a punch or kick with anything beyond moderate force will shatter the bones in his arms and legs. Even so, he still possessed impressive physical durability, and his drive allowed him to withstand the drawbacks of One For All for the most part. Despite the intense drawbacks of One For All, Izuku's wits provide him with ways to use One For All that is still effective in battle. He also retains his ability to act instinctively based on his notes and possesses basic hand-to-hand combat knowledge. By applying those correctly, Izuku is able to fight toe-to-toe with even the strongest students of Class 1-A, such as Katsuki and Shoto.

Under the tutelage of Gran Torino, Izuku acquired more control over One For All, leading to the creation of Full Cowl, a technique that would eventually become a key component of his fighting style. With Izuku gaining greatly enhanced maneuverability, strength, and a significant reduction in the physical backlash created when using his Quirk uncontrollably, he was able to drastically improve his overall fighting capabilities; his newly attained abilities garnered praise from Gran Torino, who noted that Izuku was on a higher level than he was compared to the Sports Festival.[11] This specific improvement enabled Izuku to compete more closely with his classmates in the physical aspects of the Hero Course and even allows him to fight properly against top villains like the Hero Killer: Stain, who had single-handedly bested various Pro Heroes.
As Izuku's mastery over his Quirk improves, so do his practical skills. Also, when his skills and experience increase, so does his confidence, which is said to be a source of inspiration to his classmates as well.[5] His body, however, still remains relatively vulnerable to One For All's drawbacks, which gives Izuku a disadvantage against enemies like Muscular or Overhaul, whose Quirks were proven to be too powerful against One For All's weaker outputs, forcing scenarios where Izuku had to sacrifice his body in order to go all out. In order to protect his own body, particularly his arms, Izuku eventually develops his own unique fighting style, diverging himself further from All Might's.

Currently, Izuku is acknowledged by his classmates as a strong, reliable, leading figure, with both his strength and intelligence being respected equally. However, Izuku's Quirk is still an enigma for them (including Izuku himself), which makes him an unpredictable ally for better or worse. As Izuku keeps growing, so does One For All, and with the prospect of having new abilities unlocked in the future, Izuku has to work even harder in order to fully dominate the Quirk that was passed to him.

By the time of the Paranormal Liberation War, Izuku's skills have grown exponentially to the point that he is able to fight alongside exceptional Pro Heroes such as Eraser Head, Gran Torino, and even the current number one Pro Hero, Endeavor. But his biggest feat thus far is holding his own against the Grand Commander of the Liberation Front, Tomura Shigaraki, who has inherited All For One and has a modified body with strength comparable to All Might, and forcing the all-powerful villain on the defensive despite the latter easily overpowering the top Pro Heroes.

Following the aftermath of the Paranormal Liberation War, Izuku has displayed even greater mastery over his Quirks and showcased the ability to easily outmaneuver his enemies with Blackwhip and 45% of One For All, detect danger without gaining sensory overload, prove En wrong by creating a new Ultimate Move using Smokescreen, and easily alternate between his arsenal of Quirks in his fights with Muscular and Lady Nagant. In his fight against Class 1-A, Izuku displayed himself to be easily capable of fighting on even terms with some of U.A. High School's most powerful students and was shown capable of completely dominating them even when severely outnumbered before succumbing to exhaustion and stress.

During the course of the Final War, Izuku has improved over the span of a month, where he is the only one who has a chance at defeating the fully powered Tomura, and in their final encounter, he has achieved equal standing with Tomura in terms of strength and speed despite the latter changing into his final form. Later in the fight, Izuku demonstrates a level of immense power that he is easily capable of annihilating Tomura's fingers and arms, with Tomura himself even acknowledging Izuku could possibly finish him off with a single fully powered blow if he really wanted to, but since he refuses to kill him, is forced on the defensive instead.

Upon becoming paralyzed by the recoil of Gearshift, Izuku displayed his remarkable experience with his Quirks, using Blackwhip to puppeteer his entire body and transfer Gearshift to Tomura by force. Transferring each Quirk dealt such a severe blow to Tomura's consciousness that the Villain's body instinctively entered its defense form before Gearshift was transferred, and only continued to mutate as it took more damage. Using Blackwhip to keep moving, Izuku managed to overcome the massive cluster of fingers created by Tomura's body, and fully transfer all the Quirks, including One For All itself, to completely break through the shell of hatred in his heart.

Even after sacrificing One For All and having to utilize the Quirk's embers, Izuku was still the only hero capable of harming Tomura, whose body was now in control by All For One’s lingering vestige. Despite being weakened and completely outnumbered, All For One viewed only Izuku as a threat, despite the countless other Heroes who had arrived to join the final fight. Upon striking "All For One" with his final smash, he committed his greatest feat of strength ever seen, not only destroying Tomura's body, but also completely clearing the massive storm above both Japan and North America, ending the war once and for all; the clear skies Izuku created from his smash would end up lasting for over a week.

Trained Muscles: Usage of One For All requires the user to have strong muscles, as One For All is a lot to handle and could cause the user's body to be blown apart if they don't possess the necessary bodily strength. Having been trained by All Might for 10 months in order to get his body physically ready to inherit One For All, Izuku gained a muscular physique that lets him perform at parameters higher than that of an average student outside U.A.'s hero course. During the Quirk Apprehension Test, he demonstrated a grip strength of 56 kilograms and the ability to run the 50-meter dash in 7.02 seconds (15.93 mph/25.64 kph). Even after these events, Izuku diligently trains his muscles every day and becomes physically stronger throughout the series. He is often seen running laps and using dumbbells or grippers to train during his free time. Izuku can also be observed doing the air chair exercise during the breaks between classes.
Overwhelming Stamina: Izuku has shown on many occasions that he is capable of handling large amounts of pain. Such times were mostly side-effects of overusing his Quirk and frequently led to various broken bones. Izuku is able to avoid those repercussions by staying in a safe range of One For All power output (the last recorded being 45%).

Should he be forced to output more power, Izuku is still capable of fighting decently even with broken limbs thanks to the effects of adrenaline, but will succumb to exhaustion a while later. Izuku also has to be wary of his arms, which have grown damaged due to his repeated injuries and could eventually stop working altogether if he doesn't restrain himself.

After multiple months of hard work and training with the No. 1 Pro Hero Endeavor, Izuku has become much sturdier and resilient when it comes to the drawbacks of his Quirk, allowing him to withstand the recoil from 100% attacks without being instantly incapacitated. He has also shown an even greater pain threshold, when he managed to endure multiple smash attacks at 100% and attacks from Tomura while still standing.

Izuku has shown to even be capable of operating for days on-end without eating or sleeping, going across Japan and fighting multiple villains. Even when severe sleep deprivation and physical exhaustion accumulated, Izuku still fought against powerful villains for nearly a month and made it very difficult for his former classmates to restrain him for a lengthy period of time before finally collapsing. By the time of the Gollini Invasion, it's implied that Izuku's efforts were so militant back then, that it's the reason Villains began referring to him as one of the "jailbreaker hunters" and recognizing the boy off the color of his costume alone.[12] Izuku was also able to withstand overusing Gearshift after its five minute limit was up, though had to wait several minutes to cool down or face complete loss of breath.

Later in his final battle with Tomura, Izuku showed to be capable of battling the villain even when experiencing near paralyzing pain and being unable to breathe properly due to the recoil of Gearshift. After All for One regains control over Tomura's body, Izuku proves able to continue fighting the villain even with all the damage accumulated earlier in the battle and only using the remaining embers of One for All.

Overwhelming Strength: Even without his Quirk, Izuku has shown high levels of physical strength for a person his age. During his training with All Might (who weighs 255 kilograms or 562 pounds), he was shown to be able to lift him on his back while walking. During the sports festival, he could lift a slab of metal roughly the size of his body and wield it as an effective weapon to cleave a one-point bot in two. Demonstrably, using One For All at steadily higher percentages ends up enhancing his body to superhuman levels in order to be capable of doing so.

When using One For All, his strength further increases to a variety of boundless levels: at 5%, he can shatter metal pillars with a single punch, at 8%, he can lift a steel I beam one-handed. At 15%, he could lift several vehicles in the air with the aid of Blackwhip. At 30%, he can lift a bus full of people one-handed and run fast enough to evade Tomura's Decay and restrain the enhanced Tomura with aid from Blackwhip and his anger.

During the Dark Hero Arc, Izuku's strength increases even further and he can now use 45% as his regular output with no backlash. Using 45%, he could defeat a weakened Muscular with a single punch when he was unsuccessful before, casually collapse a building when fighting his classmates, and even managed to break out of Fumikage Tokoyami's Ragnarök, shocking his friends.[13][14]

At 100%, Izuku's strength surpasses even the level of All Might, this allows him to commit astonishing feats. He could easily destroy a massive Villain Bot with a single punch, annihilate a twelve story building, create torrents of wind pressure with a flick of his fingers, and create a massive explosion with a single punch.

With the Second User's Quirk, Gearshift, and the Third User's Fa Jin combined, he can make his punches even faster and build immense kinetic energy feedback, inflicting catastrophic damage to "Tomura" during the Final War, as each punch breaks the sound barrier, to the point Mirio notices the delayed sound of the punches before it can be heard. This combination increases his strength from his 100% limit to what is described as 120% in power. Tomura admits that if Izuku landed a direct attack without holding anything back, even his body wouldn't be able to regenerate.

In the final battle against All For One, despite only possessing the remaining embers of One For All, he was still the only one capable of harming the villain. With his final strike, he made his greatest feat of strength yet when he not only destroyed Tomura's crumbling body and reduced it to ashes, but also blew away the massive storm created by Shoto, Endeavor, and Dabi, clearing the weather of not only all of Japan, but also across America. This final attack was also so powerful that America was still experiencing strong winds days after it happened.

Afterwards, Izuku is also shown to be capable of easily lifting debris and rubble despite not using his remaining One For All embers. Even compared to the pros, Izuku demonstrates a high degree of bodily strength and keen insight into how to leverage it best that isn't tied to any Quirk.
Overwhelming Speed and Reflexes: Izuku possesses great speed and reflexes with and without Full Cowl. He can react in time to defend from Shoto's ice which has been shown to occur in the literal blink of an eye and can keep up with Katsuki's movements in their first fight.

When using Full Cowl, his reflexes and movement speed elevates to higher levels; at 5%, he can keep up with Tenya's Recipro Burst which can move faster than the eye can see, at 8%, he proved to surpass Katsuki's own speed and quickly and easily overwhelmed Hitoshi in combat in spite of Hitoshi's improvements, at 20%, he could outpace Overhaul and at 30%, he can keep up with the enhanced Tomura's speed. At 45%, he was capable of keeping up with Lady Nagant's bullet and was even capable of dodging several of her shots, as well as keeping up with Muscular's movements which he previously could not follow. At 100%, his speed rises to levels rivaling or even surpassing that of All Might, which allows him to casually blitz capable villains and move several times faster than the eye can see. During his fight with Overhaul, he could completely out speed the villain and move fast enough to create afterimages, and later completely overwhelm him with an instantaneous rush of punches. When fighting against Tomura Shigaraki, he could effortlessly blitz the villain and severely damage his weakened body, despite him possessing speed rivaling that of All Might and outclassing that of Gran Torino.

With his Faux 100%, Izuku's speed is on par with All Might's in his prime. Izuku overtook a already fired and moving sniper bullet from Lady Nagant. This allowed him to reach and push Overhaul aside, even before the bullet was able to finish the last small part of the entire distance. With this technique, his speed is so great that, even in an exhausted state, it took the combined effort of Class-A just to catch up with him.

After Izuku unlocked and mastered the Second User of One For All's Quirk, Gearshift, his speed is incredibly enhanced, enabling him to leave the sound of his attacks far behind his movements. His speed has increased so drastically that every punch he makes delayed a sound before it can be heard. "Tomura" stated that even his eyes are completely incapable of keeping up with him at this speed. More impressively, Izuku is shown to be able to react to Tomura in a millisecond and cut his fingers off the instant they touched his face before his Decay could activate. However, after his Danger Sense was stolen, Izuku's reflexes have taken a sharp downward spiral, but was still able to react to Tomura's onslaught of attacks that blasts him all the way to Mt. Fuji.

Overwhelming Durability: Izuku has shown the ability to withstand explosions from Katsuki without One For All and with 5% he's taken building-sized explosions from Katsuki and attacks from Muscular. At 30% of his power, he's withstood blows from the enhanced Tomura, who is said to have power rivalling All Might himself. At 45%, he withstood being shot by Lady Nagant and even managed to survive a massive explosion triggered by All For One. Upon facing his classmates, Izuku was capable of withstanding several powerful attacks such as Fumikage's Ragnarök, ramming full-speed into Shoto's Heaven-Piercing Ice Wall, and even withstanding a collapsing building with little to no injuries.

During Izuku's fight with Flect Turn, he showed to be capable of withstanding many of his own smash attacks being reflected against him and sending him crashing through the surrounding area multiple times. Later in the fight, he survived being shot by multiple lasers and lost a significant amount of blood, yet he continued to battle the villain fiercely despite his injuries.

At 100%, Izuku's durability and endurance rise to extreme levels, making him appear virtually invulnerable to physical trauma. In his fight against Tomura Shigaraki, he could withstand several attacks from the PLF leader and his own Quirk's backlash. In his fight against Nine, Izuku proved easily capable of completely nullifying several of the villain's attacks. However, Izuku's durability has shown to depend on the amount of injuries he has sustained, with minimal injuries providing the greatest results.

In his final battle with Tomura, Izuku was shown to be capable of receiving a powerful punch from the Villain with no injuries when Tomura's Quirks were erased, and later survived a powerful explosion triggered by the Villain as soon as he regained his Quirks. Using Blackwhip to shield himself, he managed to survive a barrage of attacks from the fully powered Tmura that sent him across the country all the way to Mt. Fuji, with the Quirk helping him avoid lethal wounds. Izuku goes on to withstand being shot by Tomura's black lightning and Impure Beam Quirks, with the latter sending him crashing hard into the ground. Using Blackwhip to control his body, Izuku was able to continue battling Tomura despite his injuries, with the Quirk allowing him to take several more attacks from the Villain yet remain in the fight.
Keen Intellect: Izuku has proven to be exceptionally intelligent on many occasions, displaying both keen observational and analytical skills as well as sharp intuition and resourcefulness. His grades are among the highest of his class, showing that his One For All training rarely interferes with his studying. Izuku's intelligence has probably been a more useful asset to him than One For All so far. Izuku is a quick learner, which has helped him figure out most of One For All's mechanisms in a short span of time and work around its limitations. While some of his moves have been directly inspired by All Might (if not, outright copied), the majority of Izuku's moves and techniques were all conceived by him during sudden sparks of inspiration, proof of his creativity.

Izuku also has extensive knowledge of Pro Heroes, his classmates, and their Quirks, taking notes of them in great detail in his Hero Analysis for the Future. This is fruit of excellent observational skills coupled with his own desires in becoming a hero by learning from the best, meaning that Izuku always has a natural interest in expanding his knowledge further and further.

Izuku is an exceptional strategist and tactician. By combining his aforementioned quick learning and knowledge about Quirks, Izuku is able to devise plans that take advantage of his friends' abilities to the fullest. Izuku's calculations have been crucial at several moments of his school life, allowing him to earn victories, such as in the Battle Trial; escape dangerous situations, such as the U.S.J. Incident; and save lives, such as in the Vanguard Action Squad Invasion and Kamino Incident. Indeed, in his battle with his classmates, he used his knowledge of their powers to his advantage and easily overcame a majority of them, shocking a few of them with his skill.

His intelligence is greatly respected by everyone in Class 1-A as many of his peers look up to him for planning and follow his strategies to the bottom line. Even Momo Yaoyorozu, the smartest student in the class, has looked up to Izuku as a reference.

Adaptability: Thanks to his analytical abilities, Izuku is able to replicate the techniques of others. For example, after training with Gran Torino and gaining minor mastery of One For All, Izuku was able to duplicate Katsuki's moves during a training exercise. After training and drawing inspiration from his classmate, Tsuyu Asui, Izuku has become proficient enough with Blackwhip to generate a dark tendril from his tongue, allowing him to replicate her "Froppy Style" combat.

After unlocking more assimilated Quirks from One For All, Izuku can craft and combine some of the Quirks to make custom Ultimate Moves such as Blackchain, Faux 100 Percent, and Faux 100 Percent: Manchester Smash.

Furthermore, during his final battle with Tomura Shigaraki, upon becoming immobilized from the use of Gearshift, he used Blackwhip to flex and extend his muscles manually from within, allowing him to build up Fa Jin and swing his arm.
Leadership Skills: As a natural consequence of his bravery and strategic mindset, Izuku has displayed incredible leadership skills on various occasions.

By the start of his U.A. life, Izuku had already earned the trust of Ochaco Uraraka and Tenya thanks to his actions in the U.A. Entrance Exam, which was enough to allow him to be voted class representative early on, although he relinquished the position to Tenya shortly after. Tsuyu and Minoru Mineta also placed their faith on Izuku during the U.S.J. Incident, following his instructions with little hesitation. By the time of the First Term Final Exam, he had already fought alongside Katsuki and Shoto, who were previously antagonistic to him.

Izuku might not be aware of this, but he is one of the main motivators within his class alongside Katsuki, thanks to a combination of his heroic drive and practical intellect.

Indomitable Will: Throughout the series, and as one of his greatest traits, Izuku displayed an extraordinary level of willpower. Following his dream to become the greatest hero, Izuku develops great determination and willpower. While feeble and doubtful at the beginning, Izuku steadily developed and proved his strong willpower against far menacing adversaries, people doubting and believing in him, and proven to be stronger than many of his classmates. He was the first one to move his body after All For One induced great fear onto him and his classmates. Even when Sir Nighteye foresaw Izuku's death and Eri's failed rescue, he refused to give up and promised to change fate. He has constantly displayed the ability to never give up no matter how severe the injury. When fighting Overhaul, Izuku continuously steeled his resolve to save and protect Eri. Even after being severely injured and feeling the drawbacks of using One For All at 20%, he still kept on fighting against the villain until going all-out with 100%.

During the Paranormal Liberation War, Izuku displayed his resistance against Tomura's terrifying aura. While he did hallucinate his death for a moment, he quickly recovered from it and showed no fear when confronting the villain. When all hope seemed lost, Izuku decided to do everything in his disposal to stop Tomura, no matter what would happen to himself afterwards and knowingly going for the risk of forever losing his arms or worse. Even after shattering his arms and legs and horrifically injuring himself, he developed the Froppy Style with Blackwhip after being inspired by Tsuyu Asui and desperately attempted to capture Tomura.

After the Paranormal Liberation War, Yo Shindo notices the change and development of Izuku's willpower, stating that he gives off a totally different vibe. Even when Izuku went to confront All For One in the Haibori Woods mansion, he only showed his anger-filled eyes and determination of defeating him. During the Dark Hero Arc, Izuku's will takes a large toll as he begins to succumb to the stress and trauma of the war, as well as leaving U.A. He began to over-exert himself, under-eat, and constantly fend off villains, while showing extremely worrying behavior. He eventually decides to leave behind All Might in order to track down the PLF himself. In reality, Izuku chose to commit these actions to protect his friends from anymore harm, not wanting more people to get hurt or killed due to his actions. This behavior is further enforced after the horrific disfigurement of Lady Nagant right in front of his eyes, which further increased his rage and hatred towards All For One. Eventually, after being rescued by his friends, having Katsuki Bakugo apologize to him for his actions, and Ochaco Uraraka publicly defend him, he finally leaves behind this depressive state and steels his resolve to fight against the villains.

By the time of the Final War, even though Izuku becomes outmatched by Tomura's power, with One For All vulnerable to be stolen and the villain on the verge of destroying Mt. Fuji, Izuku still won't give up and stands against Tomura with no sign of fear. This trait is why Kudo was strongly opposing Izuku as the successor of One For All at first, not because he's a peace-seeking or his desire to save one's archenemy to be a delusional madness, but because of his strong driven notion to save anyone, whether the most vile among them or the Quirkless, as each one of them as an innately human heart. His willpower was so motivated that even with his muscles being torn and suffering through Gearshift's recoil backlash, Izuku still keeps on fighting through. Even within the realm of One For All, and All For One, Izuku's extraordinary willpower was so strong that he was able to withstand against Tomura's immense hatred inside of his core, and make Tomura bend to his will in the final battle. Even after losing his arms, and All For One taking back control of Tomura, Izuku refused to give up fighting. Despite losing his Quirk with only the last embers of One For All, he still manages to turn the spark into a raging inferno similar to All Might's, as he was able to push himself to the brink and dealt the finishing blow to destroy All For One's vestige once and for all, at the cost of ending Tomura's life, with the villain conceding in defeat before succumbing to his injuries and dies as his body disintegrates into ashes.

History Expertise: Izuku is teaching high school history and hero history, indicating he has a good amount of knowledge on the subject.

One For All (ワン・フォー・オール Wan Fō Ōru?): Transferred to him from Toshinori Yagi, Izuku's Quirk allowed him to stockpile an enormous amount of raw power, allowing him to significantly enhance all of his physical abilities to various boundless levels. This resulted in unbelievable levels of strength, speed, stamina, agility, and durability. When Izuku activated One For All, red, vein-like lines course throughout the empowered part of his body.

Izuku could focus the stockpiled power into a single body part, or spread it across his entire body evenly, though, focusing the power in a single part puts a greater strain on that part of his body. He was also able to control what percentage of his full power that he uses. Since he was not born with this power, his body was not naturally suited to handle it, however, over time and with continued training with it, his body has become more accustomed to bracing for the strain. By the Dark Hero Arc he was able to handle and make use of 45% of his full power without breaking his bones, and in his final confrontation against "Tomura Shigaraki", he was able to demonstrate a sufficiently high level of proficiency on the Quirk to use 100% of his stockpiled power to match the monstrous strength and speed of the fully evolved villain without inflicting damage upon his body like his previous uses, thanks to using Gearshift and Fa Jin.
In addition to the stockpiling power, Izuku also had access to a subconscious realm where vestiges of the consciousnesses of the previous One For All holders dwell. These vestiges could trigger Izuku to activate One For All without any conscious input from himself, as seen when he was under the control of Hitoshi's Brainwashing Quirk and illusionary shadows of these echoes appeared in his vision. Izuku had little to no control over this aspect of One For All, being unable to freely enter or exit, his body not being fully materialized, which limited his movement within the realm, and only being able to talk through muffled sounds since his mouth has not fully manifested yet. However, Izuku had reached the point where he can freely communicate with the vestiges of the previous users while still conscious. Izuku is the first holder of One For All known to have gained access to this realm while still alive.

Izuku was granted access to the Quirks of the previous owners of One For All, but he has since transferred all of them to Tomura in an effort to defeat him.[20] In addition to transferring the Quirks of One For All, Izuku also transferred One For All itself to Tomura, leaving him with only the "leftover embers".

Gearshift (変へん速そく Hensoku?): The Quirk of the second user, Kudo. This Quirk allows Izuku to change the speed and/or velocity of any target he touches, including himself. This allows him to greatly accelerate his own speed and/or the velocity of his target, and enhance the impact force of his own strikes. After years of being empowered within One For All, Gearshift has evolved into an unusual power that cannot be wielded the usual way. It has also been designated as a last resort. Izuku forcibly transferred this Quirk to Tomura so that he can defeat him from the inside of his soul.
Fa Jin (発はっ勁けい Hakkei?): The Quirk of the third user, Bruce. This Quirk allows Izuku to build up and store kinetic energy by performing repetitive movement. He can later release this stored energy as an explosive burst of speed and power.Izuku forcibly transferred this Quirk to Tomura so that he can defeat him from the inside of his soul.
Danger Sense (危き機き感かん知ち Kiki Kanchi?): The Quirk of the fourth user, Hikage Shinomori. Formerly residing in One For All, this Quirk allowed Izuku to detect threats in the surrounding area. Due to the amplification of One For All, the detection caused a stabbing sensation in his head and took a toll on his body. This Quirk was stolen by Tomura during the Final War.
Blackwhip (黒鞭クロムチ Kuro Muchi?): The Quirk of the fifth user, Daigoro Banjo. This Quirk allows Izuku to generate tendrils of black energy from his body that are good for grappling. It is useful for grabbing things from long distances, capturing opponents, and increasing Izuku's mobility. Izuku forcibly transferred this Quirk to Tomura so that he can defeat him from the inside of his soul.
Smokescreen (煙えん幕まく Enmaku?): The Quirk of the sixth user, En Tayutai. This Quirk allows Izuku to generate a thick cloud of purple smoke from his body. This smoke can cover a very wide area and obscure peoples' vision. Izuku forcibly transferred this Quirk to Tomura so that he can defeat him from the inside of his soul.
Float (浮ふ遊ゆう Fuyū?): The Quirk of the seventh user, Nana Shimura. This Quirk allows Izuku to suspend himself in mid-air, granting him flight. Izuku forcibly transferred this Quirk to Tomura so that he can defeat him from the inside of his soul.

Former Equipment
Costume Zeta (コスチュームZゼータ Kosuchūmu Zēta?): The sixth iteration of Izuku's hero costume. After his previous outfit was almost completely destroyed, this new patchwork includes most of the primary features of the previous versions, including the improved arm bracers and the iron soles to support his arms and legs. The hood has been removed, replaced with Gran Torino's cape as a scarf. The damaged mask from his previous costume remains a part of this one.

Iron Soles (アイアンソール Aiansōru?): Created by Mei, these Iron Armor Soles attach to Izuku's signature red shoes. Upon kicking something, the soles absorb the impact and redistribute the kinetic energy back out to increase the impact strength of Izuku's kicks.[50] Izuku requested the soles to strengthen his kicks after resolving to change his fighting style.
Air Force Gloves: Created by Mei, these gloves allow Izuku to focus and aim bursts of pressurized air that he creates by flicking his fingers. This allows Izuku to use long-range projectile attacks using One For All. After Izuku's battle with Tomura during the Paranormal Liberation War, the gloves, along with the arm bracers, were completely destroyed, but he later received a new version of them from Mei.
Mid-Gauntlet (ミッドガントレット Middo Gantoretto?): Presumably created by Melissa after the Paranormal Liberation War, similar to the Full Gauntlet, it allows Izuku to use One For All's power in higher percentages without the worry of harming his body, though it will break if used at 100%. Following his fight with Lady Nagant, Izuku's left Mid-Gauntlet is partially destroyed, leaving it practically useless. He later receives new replica versions of the Mid-Gauntlets from Mei.
Full Gauntlet (フルガントレット Furu Gantoretto?): Created by Melissa, it was given to Izuku after she figured out that he was limiting his output of One For All, during the faux villain course at the I-Island Expo. The device allowed him to use his Quirk at higher percentages without the risk of self-injury. The gauntlet was later destroyed at the climax of Izuku and All Might's fight against Wolfram.

Armor Suitcase: A mechanical briefcase that can transform into a mechanized suit, being a technology-based Hero costume that looks markedly like his Costume Zeta. It was created by Melissa Shield and Mei Hatsume, funded by the former Class A members, led by Katsuki, who also gave a very large donation in the funding, allowing Izuku to rejoin them as an active hero. The suit is based on the Armored All Might suit previously designed by Melissa, using data from the final battle between All Might and All For One. The suit is capable of mimicking some of the Quirks Izuku used when he had One For All.[2]

Jet boots and a jet pack making him capable of flying like Float.
An extendable whip and cable extensions to swing off of like Blackwhip.

Izuku was originally planned to be an adult as seen in the one-shot My Hero.
In the early concept stages of My Hero Academia, Izuku was known as "Mikumo Akatani". He had a longer and curlier hairdo, with bangs blocking one of his eyes. He was Quirkless in this concept, relying more on makeshift gadgets and luck to deal with obstacles. His hero costume was also slightly more intimidating. The costume was shown in a sketch having an orange color scheme.
Kohei Horikoshi once commented that he was unsatisfied with Mikumo's design, especially his hair. This made Horikoshi think up the current design with slightly shorter hair.[1] He also received suggestions from editors to give the protagonist an actual superpower, so he wouldn't naturally fade into the background.
According to Izuku's profile in Volume 1:
His favorite food is Katsudon.
He was deliberately designed to look plain.
Regarding Izuku's academic life and performance, his U.A. data is as follows:
Student No. 18 in Class 1-A.
Ranked seventh during the U.A. Entrance Exam.
Ranked twentieth (last) for the Quirk Apprehension Test.
His fifty-meter dash record is 7.02 seconds. His previous record was 7.49 in middle school.
His grip strength record is 56 kilograms (123.459 pounds). His previous record was 40 kilograms (88.185 pounds) in middle school.
His softball throw record is 705.3 meters (2313.98 feet). Without his Quirk, it's 46 meters (150 feet).
Ranked fourth in Class 1-A's mid-term grades.
Ranked in the Top 8 of the U.A. Sports Festival First-Year Stage.
Izuku received only one nomination from Gran Torino for his U.A. Sports Festival performance, technically making him the tenth most nominated Class 1-A student.
Scored seventy-one in the Provisional Hero License Exam.
Initially, Izuku was voted to be 1-A's class representative before he decided to willingly pass the position over to Tenya.
Izuku's surname contains the kanji for "green" (緑 midori?) and "valley" (谷 ya?), and his given name contains "coming out/being from a certain place, one's turn to go on" (出 izu?) and "long ago, old story" (久 ku?).
"久" is also homophonous to "nine" (九? usually read as kyū), which refers to him being the ninth user of One For All.
"Deku" (デク?) is another reading of his first name, Izuku (出久?). Written with different kanji, it can refer to a wooden figure or puppet (木偶でく deku?), which is a term often used as an insult for someone who can't do or achieve anything.
Izuku's nickname, "Deku," was given to him by Katsuki when they were children as an insult.
According to Kohei Horikoshi, the inspiration for the name Deku was from Kenji Miyazawa's poem "Ame ni Mo Makezu" (Be Not Defeated by the Rain).
Later, Ochaco finds the nickname inspiring and says that "Deku" gives off a feeling of "I can do it" (頑張がんばる ganbaru?), because of its similarity to the word meaning "to be able to do" (できる dekiru?).
In the Funimation dub of Episode 1, Katsuki implies that Izuku's nickname is an abbreviation of a different insult: "Defenseless Izuku," hence Deku.
In that version of the anime, the scenes that directly discuss the nickname's Japanese definition are typically written around, though it's still referenced roundaboutly in relevant dialogue (i.e. the flashback of Katsuki creating the nickname in Episode 7, and grafting the insult on to the name instead of plainly stating its definition.)
Also as a result, Ochaco's primary reason for liking the name "Deku" in the dub comes from her believing that it sounds like a great Hero name on its own, additionally mentioning that she finds it cute.
Izuku's rankings in the Popularity Polls are as follows:
Izuku ranked first in the first Popularity Poll.
Izuku ranked second in the second, third, fifth, sixth, seventh, eighth, ninth, and the Global Popularity Polls.
Izuku ranked second in every single voting region for the Global Popularity Poll with the exception of Europe, where he placed first.
Izuku ranked third in the fourth Popularity Poll.
Izuku has the most Hero costumes variant of any character in the series, with ten (eleven if counting his temporary costume in the U.S.J. Arc).
He shares his birthday with Mirio Togata and Rapt Tokage.
His Quirk is listed as "Super-Power" (超パワー Chō Pawā?) in public records, in order to protect the secret about One For All.
Izuku's alpha costume cost only ¥40,380 ($370.53 U.S. dollars) to make.
Izuku's later costumes share the same designer as Shoto's.
According to Izuku's Ultra Analysis profile:
Due to the mysterious nature of One For All, the databook considers Izuku to be a dark horse candidate for the position of Number 1 Hero.
He still has and cherishes the thank you letters that he received from Kota and Eri.
His personality describes him as a "get-it-done fanboy".
After leaving U.A. and going rogue from the other Heroes, Horikoshi admitted that Izuku's dirty appearance and damaged costume took him extra long to draw.
Izuku's Japanese voice actress for when he was a child, Akeno Watanabe, also voices Mika Jiro and Midnight.
Izuku is one of three characters (along with Nine and Gigantomachia) with the third most amount of Quirks, possessing a total of seven Quirks.
