Izuku Midoriya ( (みどり) () (いず) () Midoriya Izuku?), also known as Deku (デク Deku?), is the main protagonist of the My Hero Academia manga and anime series.

Even though Izuku was born Quirkless, he manages to catch the attention of the legendary hero All Might, due to his innate heroism and a strong sense of justice, and has since become his close pupil, as well as a student in Class 1-A at U.A. High School. All Might passed on his transferable Quirk to Izuku, making him the ninth and current holder of One For All.

Appearance[]

Izuku is somewhat short for his age, his round face is framed by a short mess of fluffy dark-green hair which sticks up at odd angles around his head, casting noticeably dark shadows onto itself. His eyes are large and somewhat circular, their irises the same green color as his hair, which at times are very watery, and are usually stretched quite wide, giving him an innocent, energized appearance. He has a set of four symmetrical freckles in diamond formations, one on each cheek.

Though he was initially very skinny, Izuku has gained toned muscles after his ten months of extensive training with All Might, and as the series progresses, these are shown to become more developed and defined as he gradually grows stronger.

After his battle against Shoto Todoroki, the fingers on his right hand became slightly deformed, and his hand shows visible scarring. His right arm was further damaged after his intense fight with Muscular, leaving many more scars. Following his recovery after the previously mentioned fight, Izuku wears a black compression sleeve on the upper portion of his right arm in order to support the heavy damage it sustained: it is partially visible when he wears short sleeves.

During his time in Junior High School, he wore a plain black gakuran uniform with yellow buttons, accompanied by white sneakers. While at home, he wears a green jinbei over a white shirt and gray sweatpants.

At U.A., he wears the standard male uniform: a light gray blazer with dark turquoise trimmings over a white dress shirt and dress pants, along with a red tie which he doesn't do up properly, leaving it much shorter than how it should be. Instead of the plain brown shoes worn by the majority of the student body, he wears his signature pair of red high tops with white soles and black laces.

Izuku's first hero costume, known as "Costume Alpha," was a green full-body jumpsuit with a red belt, elbow pads, knee pads, and gloves, along with his signature red boots. He also wears a mask with long ear-like protrusions that resembles All Might's haircut, and a respirator with a makeshift smile on it that also reflects that of said hero. The costume was severely damaged as a result of his first battle against Katsuki Bakugo and had to be repaired, so during the U.S.J. Arc and My Hero Academia - Save! Rescue Training, Izuku had to wear the U.A. gym uniform. This attire consists of a dark blue high-collared tracksuit with thick white lines over his torso and down his legs, forming the letters "U" and "A," and along with this, a respirator.

His second hero costume, known as "Costume Beta," has a few changes and now looks sturdier and more combat-ready in appearance. It includes light beige shoulder pads, and its knee pads have been extended to his legs, now reaching up to his thighs. His new gloves are also tinted light beige and are decorated with blue stripes. His respirator is now metal, diamond-shaped, and has eight holes. Izuku goes without a mask in his second suit, and although the mask is still present, he doesn't wear it much. In terms of its color scheme, it is now a darker shade of green with black outlines instead of white.

During Class 1-A's week of Ultimate Move Training, Izuku had his costume upgraded again to suit his new fighting style, Shoot Style, by adding iron soles to his red boots to increase the power of his kicks. Arm braces were added, and his knee pads now have yellow bolts fastened into them (they were originally added in his second costume in the manga). He called this collection of upgrades "Costume Gamma".

Izuku's fourth hero costume, known as "Costume Delta," makes some minor alterations from his previous hero costume. Before the U.A. School Festival, Mei Hatsume creates support gloves to better help him use his powers for long-range attacks. Prior to the Joint Training Arc, Izuku adds the gloves to his hero costume and uses them in combat.

During Mission: Humarise, Izuku and his classmates at the Endeavor Agency are given special advanced stealth costumes by the World Heroes Association for their mission at Otheon. Izuku's stealth costume was redesigned based on his Delta Costume, consisting of a black suit with teal-green highlights on the lines, equipped with black iron soles and black boots. This costume also includes two silver plates on his shoulders with the letters "WHA" and two straps coming down from his upper body pads with a red button on the left.

After the Paranormal Liberation War, his costume was damaged, so he wore Gran Torino's cape, as a memoir to his former mentor and to the deceased Nana Shimura. Due to his arm bracers and gloves being destroyed, he wore four Mid-Gauntlets to support his arms and legs, as well as the old gloves from his beta costume. In addition, Izuku wore his mask much more frequently in order to conceal his identity. Interestingly, him wearing the mask now cast shadows over his eyes, which causes only his green eyes to be visible. This appearing feature is very similar to All Might's look, who has his blue eyes shine through the shadows. This is Izuku's fifth hero costume, known as "Costume Epsilon."

Personality[]

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 brave 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 in regards to 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, checking on them regularly during school activities 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 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. Izuku putting others' lives above his own can go to the extreme, to the point where he has little to no 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 listened, adapting his battle style to not put so much 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 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 the loyalty and gratitude of characters that were previously antagonistic towards him such as Tenya Ida, Shoto, Hitoshi Shinso, Kota Izumi, Sir Nighteye and even the Hero Killer: Stain.

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.[6][7][8] 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 several feats (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 greatest Hero of all time. The unwavering trust and approval Izuku receives from All Might has been vital to his development as a hero, especially when 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. 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 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 wellbeing becomes the worse it ever has been as well, neglecting to look after his basic needs like sleeping and eating. 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.

Abilities[]

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. 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 One For All: 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.[9] 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 is powered by All For One and 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.

Quirk[]

One For All (ワン・フォー・オール Wan Fō Ōru?): Transferred to him from Toshinori Yagi, Izuku's Quirk allows him to stockpile an enormous amount of raw power, allowing him to significantly enhance all of his physical abilities to a superhuman level. This results in unbelievable levels of strength, speed, stamina, agility, and durability.

Izuku can 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 is also able to control what percentage of his full power that he uses. He is currently able to handle 45% of his full power without breaking his bones, with 30% being his normal output.Template:Ref When Izuku activates One For All, red, vein-like lines course throughout the empowered part of his body.

The Quirk factors of the previous power holders have merged with the core of One For All and have drastically increased in strength since. This grants Izuku the ability to access and utilize the Quirks of the previous holders of One For All. He can even use more than one of these assimilated Quirks at a time, granting him even more options in battle. The known Quirks within One For All are:

  • Gearshift ( (へん) (そく) Hensoku?): The Quirk of the second user. 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.
  • Fa Jin ( (はっ) (けい) Hakkei?): The Quirk of the third user. This Quirk allows Izuku to build up and store kinetic energy as he moves. He can later release this stored energy as an explosive burst of speed and power.
  • Danger Sense ( () () (かん) () Kiki kanchi?): The Quirk of the fourth user, Hikage Shinomori. This Quirk allows Izuku to detect threats in the surrounding area. Due to the amplification of One For All, the detection causes a stabbing sensation in his head and it takes a toll on his body.
  • 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 capturing opponents. It is useful for grabbing things from long distances, as well as increasing Izuku's mobility.
  • Smokescreen ( (えん) (まく) Enmaku?): The Quirk of the sixth user, En. This Quirk allows Izuku to generate a thick cloud of smoke from his body. This smoke can cover a very wide area and obscure peoples' vision.
  • Float ( () (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 also has access to a subconscious realm where vestiges of the consciousnesses of the previous One For All holders dwell. These vestiges can 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 currently has 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 limits his movement within the realm, and only being able to talk through muffled sounds since his mouth has not fully manifested yet. However, Izuku has 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.

Empowerment: One of the two quirks that was forceful given to him by Tomura Shigaraki during the Arkadia City War. Enpowerment allows Izuku to empowered himself and others enhancing the physical strength and quirk. Not only this quirk power was enhanced by One for All it also made One For All much more powerful beyond anything then it was before.

Chi: One of the two quirks that was forceful given to him by Tomura Shigaraki during the Arkadia City War. Chi grant him augment and sensory abilities. Not only this quirk power was enhanced by One for All it also made One For All much more powerful then before.
