Izuku Midoriya

Izuku Midoriya (緑谷出久), also known as Deku (デク), is the main protagonist of Boku no Hero Academia.

Though originally born without a Quirk, he manages to catch the attention of the legendary hero All Might and has since become his close pupil and a student at U.A., making him the ninth user of the One for All Quirk.

Appearance
Izuku has green eyes and black curly hair with green highlights. During his Junior High School days, he wore a black gakuran uniform with yellow buttons. In U.A., he wears the standard male uniform: a light grey suit over a white dress shirt and dark green dress pants, along with a red necktie that he doesn't tie properly, making it shorter than it should be. Izuku usually wears oversized red shoes. Though initially very skinny, Izuku has gained an array of well-developed muscles after his training with All Might.

Izuku's first Hero costume is a dark green full-body unitard with a red belt, elbow pads, knee pads, gloves, and red boots. He also wears a mask with long ear-like protrusions that resemble All Might's haircut, and a mask with a smile on it.

During the Unforeseen Simulation Joint Arc, while his costume is being repaired, Izuku wears his gym clothes: a blue track suit with thick white lines over his upper body and legs, which form the letters "UA".

Izuku's second hero costume had when to a few changes, though it may have some of the original aspects it has now looks more sturdy and combat efficient in appearance.

After his fight with Shouto, the fingers on his right hand became a little deformed and he gains two scars on the sides of his hand. His right arm is further scared after his fight with Muscular, leaving various scars on his arm and bicep.

Personality
Izuku is a very timid, helpful and polite boy. Due to being bullied since childhood for being born without a Quirk, he is initially portrayed as insecure, being more reserved and not self-expressive, especially in front of Katsuki Bakugou. However, after being accepted into U.A. High and facing Katsuki during the Battle Trial Arc, he has gradually become more confident and brave.

Izuku is also very diligent and strong-willed. Since he greatly admires heroes and has always dreamed to be one since his childhood, he developed a habit of writing down notes about everything he knows about heroes and their Quirks, including even other U.A. students. Because of this practice, Izuku has developed a great analytical mind and is easily able to form complex plans in short amounts of time, often taking advantage of his allies' Quirks to put them in motion. This aspect also helps him in figuring out ways to counter Quirks used by his opponents. Izuku also has the tendency to overthink about anything that grabs his attention, which makes him start mumbling to himself a lot.

Izuku is a caring person, and will never hesitate to rescue someone in danger, even if he knows that he's not strong enough to do it. Often, he does this in a whim, taking a more careless approach than usual. Izuku has also shown to be selfless enough to try to help people with personal, emotional problems, even if it doesn't concern him.

Of all heroes, All Might is the one that has had the most impact in his life, with the hero having shaped most of the goals and beliefs that he follows since childhood. Many of Izuku's decisions and actions are inspired by his desire to become a hero similar to All Might, and thus he has a great devotion for him, to the point of emulating several of his traits.

Izuku appears to have a more brash and abrasive side to him that mostly 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 has even gone as far as to taunt Katsuki when the two of them fought when he is in this mentality. He claims that this is because he sees Katsuki as the embodiment of what someone who strives for victory should be. He also has admitted that he doesn't like this side of him very much, and tends to keep it in check.

Quirk and Abilities
One For All (ワン・フォー・オール): Inherited from Toshinori Yagi, Izuku's Quirk grants him superhuman strength and greatly enhanced agility and mobility by spreading his power through his body. Though he has yet to demonstrate superhuman speed, immense reflexes, and durability on the level of All Might, Izuku has shown to be able to properly control a small percentage of One For All's power, using it to enhance his strength, speed and agility. He has also displayed a type of mental connection to the previous users of One For All.

Recently, Izuku's reflexes and speed seem to have improved with the use of One For All, being able to hold his ground against various incoming attacks during the Provisional License exam. Izuku control of One For All has improved as he can now use 8% of One For All's power.

Moves

 * Detroit Smash (デトロイトスマッシュ): The same as All Might's move, except Izuku does it in the form of an uppercut.
 * 5% Detroit Smash (5 パーセント デトロイトスマッシュ): Izuku activates One for All Full Cowl, then jumps into the air, and delivers an enhanced downward punch to the opponent. He has also used this move in the form a straightforward punch.
 * 100% Detroit Smash (100 パーセント デトロイトスマッシュ): Izuku activates One For All at 100% and delivers a straightforward punch to the opponent.


 * Delaware Smash (デラウエアスマッュ): Izuku flicks his finger to create a powerful shock wave. Doing this fractures said finger, limiting the time he can use this move without gravely injuring himself up to 10 times.
 * 1,000,000% Delaware Detroit Smash (1000000 パーセント デトロイトデラウエアスマッュ): Izuku uses One For All 100% that is also boosted by his adrenaline and delivers a powerful smack with incredible force that blasts the opponent away. This 100% adrenaline-enhanced move is powerful enough to overpower Muscular's Muscle Augmentation and incapacitate him.


 * One For All Full Cowl (ワン・フォー・オール フルカウル): This technique allows Izuku to now activate 8% (previously 5%) of One For All throughout his body, letting the power course and flow through him instead of concentrating it in one location. According to Izuku, this technique gives him greater maneuverability. Activating this technique gives him enhanced strength, speed, mobility and agility. It also prevents him from breaking his bones when attacking.
 * One For All Full Cowl: Shoot Style (ワンフォーオール フルカウル シュートスタイル): While using One For All Full Cowl, Izuku uses a fighting style that focuses more on kicking.
 * One For All 100%: A technique that allows Izuku to attack using the full power of One For All throughout his body.

Overall Abilities: Izuku has decent prowess and physical parameters above the ordinary student. However, he has improved his physical capabilities through training, enough to provide valuable assistance during the battle against Stain. During his second battle with Katsuki, Izuku was able to hold his own against Katsuki and was slightly able to fight back even though he was still outmatched in strength and speed; Izuku was also able to injure Katsuki, which shows a drastic improvement in Izuku's abilities as in his first battle with Katsuki he wasn't able to inflict any damage at all.

Keen Intellect: Izuku has proven to be exceptionally intelligent on many occasions. He has displayed keen skills of observation and analysis. It is usually his intelligence that has helped him more than his Quirk. Izuku is able to formulate strategies that takes advantage of the situation and uses his knowledge to creatively utilize the Quirks of other people to their full potential, such as working together with Tsuyu and Minoru to escape the villains at the flood zone in the USJ. Izuku also has extensive knowledge on Pro Heroes and their Quirks as well. Izuku's intelligence has allowed him to figure out One For All's mechanisms, allowing him to utilize the Quirk more efficiently in a short space of time. Gran Torino even compliments Izuku's intelligence, saying that Izuku is the type of person who thinks before he acts.

High Pain Tolerance: Izuku is shown many in many occasions that he is able to handle and bear with a lot of pain, such times are mostly because of the repercussion of over using his Quirk; however, he can still manage to move his body despite feeling excruciating pain.

Equipment
Costume Gamma (コスチューム): This is an upgrade to Izuku's second costume that Mei Hatsume created following Izuku's decision to change his fighting style, thus creating Shoot Style. The new additions consist of arm braces to support Izuku's arms in order to prevent further damage, and iron armor soles to enhance his kicking power.
