Izuku Midoriya

Izuku is a very shy, reserved, and polite boy, frequently overreacting to abnormal situations with exaggerated expressions. Due to years of being looked down upon by Katsuki for not having a Quirk, he is initially portrayed as insecure, whiny, vulnerable, and not expressive. These traits are especially present around Katsuki, who also constantly questioned him about his aspirations to become a hero. However, after being accepted into the UA, making new friends, and facing Katsuki during the Battle Trial Arc, Izuku gradually matures into a more confident and courageous person who is always eager to prove himself as a hero, eventually developing strong leadership skills, which combined with his passion and strategic skills, turned him into a central figure within Class 1-A alongside Katsuki.

Izuku is a rather diligent and strong-willed student, being extremely (and sometimes frighteningly) enthusiastic about hero-related topics. His dream leads him to write notes about everything he learns regarding the heroes' quirks and fighting capabilities. Thanks to this practice, Izuku has developed a great analytical mind and can form complex battle plans within seconds, considering the best ways to utilize the quirks of allies and enemies alike to his own advantage.

Izuku externalizes his remarks through endless mumbling, a habit that annoys or frightens his peers. Izuku often writes down his observations in a variety of notebooks he titles Hero Analysis for the Future, checking them regularly during school activities or at night.

Izuku is caring and emotional, never hesitating to help or rescue anyone in danger, even though he knows he might not be strong or qualified enough to do so. He often does this on instinct, taking a more careless approach than the overthinking he goes through and putting himself in harm's way to protect someone. All Might states 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 extremes, to the point where he has little to no sense of self-preservation. Katsuki speculates that the bullying Izuku received for being without a Quirk made him internalize that his life has less value. Izuku will routinely break his arms for the sake of others, even if it isn't completely necessary, such as requiring Shoto to unlock his full potential using his fire side. This can make Izuku somewhat short-sighted, as he continued to break his arms despite warnings that he could permanently paralyze them and cut short his hero career. Eventually, Izuku relented, adapting his battle style to put less strain on his body. Although, when he is in a particularly difficult situation, he abandons old habits.

Izuku has been known to help or lecture people with personal and emotional issues, regardless of whether it was his business or not, claiming that a hero should meddle in other people's lives. This audacious spirit, while initially seen as disconcerting or even insane by others, is also recognized by many, and has earned him the loyalty, gratitude, and respect of characters who were previously antagonistic to 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 to be well-versed in their history, sometimes even surprising the heroes themselves with his vast knowledge of their abilities and past exploits. [6][7][8] He is prone to ramble on about the heroes he knows, often bringing up their history and accomplishments, while also being eager to share this knowledge with others. Of all the heroes, the Symbol of Peace, All Might, had the most impact and shaped Izuku's life. Many of Izuku's decisions and actions stem from his desire to become a Pro Hero similar to All Might, and thus he has a great deal of devotion towards him.

Izuku is an avid collector of All Might merchandise, is aware of his numerous feats of heroism (no matter how small) and emulates many of his traits. Having inherited his Quirk, one of Izuku's current priorities is being able to live up to his idol's legacy, as he is always looking for ways to improve his use of One For All, well aware of the immense pressure that comes with beating the greatest Hero of all time. times. The unwavering trust and approval that Izuku receives from All Might has been vital to his development as a hero, especially when the aforementioned feelings of insecurity and unworthiness plague his mind.

Izuku seems to have a bolder and more abrasive side, which usually comes out when he finds himself in combat. This side of him makes him act more like Katsuki, being quite loud and unflappable, and also having a strong drive to win. He claims this is because he sees Katsuki as the embodiment of what someone fighting for victory should be like. He also admitted that he doesn't like that side of him very much and tends to keep it in check. He does, however, find himself giving into this almost savage rage when in dire situations and facing opponents who have brutally injured the people he cares for, such as 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. Although he initially believes Tomura to be a madman who just wants to senselessly hurt others, after learning about his tragic history and feeling the pain in his heart through the connection between One For All and All For One, it reinvigorates his belief that one A great Hero is someone who saves others, not kills, and therefore wants to know how they became villains and see if there is any way to avoid a fight, although he admits that he may well have to kill Tomura. While he is not naïve to this ideology and resorts to violence if left with no other option, such as during his second fight with Muscular, he genuinely wants to reach out and help villains recover and reform, even giving Kai Chisaki (with whom he was still resenting) the chance to save his boss if he made up with Eri. At the same time, Izuku wishes to save Tomura from his life of villainy and pain, even when such a notion seems unlikely and is considered pretentious by others, showing his great sense of humanity.

After the conclusion of the Paranormal Liberation War, Izuku began to drastically change his behavior. After suffering through the trauma caused by the war, seeing countless innocent people have their lives ruined by the current state of society, having All For One relentlessly target his Quirk, and taking it upon himself to protect his friends, Izuku has grown colder. and distant from others. When All For One promised to break him physically and mentally, he became increasingly paranoid about how much damage he would bring to those around him. The overwhelming stress and burden resulted in him rushing into fights and leaving behind All Might and the other heroes watching over him so no one else would get hurt. His disregard for his own well-being becomes all-time worse, neglecting to take care of his basic needs like sleeping and eating. Katsuki noted that this behavior is very similar to how All Might was when he was the Symbol of Peace. This serious and increasingly serious side of him made civilians take notice that he didn't look like a hero. After his UA friends come to him and accept him back, these traits seem to have diminished, with him now determined to stop All For One alongside his friends, teachers, and allies.
