In the world ofMy Hero Academia, nearly every individual is born with a unique superpower known as a Quirk. These Quirks define how people live, work, and even dream. But for Izuku Midoriya more commonly known as Deku life begins with a crushing realization: he is Quirkless. Despite this, he dreams of becoming a great hero like his idol, All Might. Deku’s journey from being powerless to inheriting one of the most powerful Quirks ever known, One For All, is a story of hope, determination, and the true spirit of heroism. Understanding how Deku gets his Quirk sheds light on the themes of destiny, choice, and legacy that run throughout the series.
Deku’s Life Before One For All
The Reality of Being Quirkless
Deku was born into a world where around 80% of the population possesses a Quirk. He idolizes heroes, especially the legendary All Might, and spends his childhood studying their abilities and actions. However, at the age of four, after a medical examination, he is told that he will never develop a Quirk. This diagnosis is devastating, not only crushing his dreams but also subjecting him to ridicule and bullying from peers, including childhood friend Katsuki Bakugo.
Despite being Quirkless, Deku remains devoted to the idea of being a hero. He takes notes on hero behavior, tactics, and abilities, filling notebooks with detailed observations. His mind becomes his greatest asset a sign that even without a Quirk, he still has the heart and mind of a hero.
A Heroic Act Without Powers
One of the turning points in Deku’s early life comes when a villain attacks Bakugo in the city. While many trained heroes hesitate, Deku, without thinking, rushes in to save him. This moment of pure courage and selflessness catches the attention of All Might, who is present at the scene. It’s this act that plants the seed for Deku’s future transformation.
Meeting All Might
The Truth Behind the Symbol of Peace
After the incident, Deku meets All Might in a private setting and learns a shocking truth All Might’s true form is a weakened, skeletal version of his muscular heroic persona. A past injury limits the time he can use his powers. During this conversation, Deku asks the question that changes everything: Can someone without a Quirk become a hero like you?
All Might initially responds with disappointment, thinking that Deku’s dream is impossible. However, after seeing Deku’s bravery and spirit, he reconsiders. All Might realizes that heroism is not about powers alone it’s about action and courage. This revelation leads him to make a life-altering decision.
The Inheritance of One For All
What is One For All?
One For All is a unique and powerful Quirk passed down from one individual to another. It accumulates power over time and allows its user to access tremendous physical strength. But One For All also carries the essence of its previous users, granting not just power but also memories and, eventually, access to their Quirks. Unlike natural Quirks, which are linked to genetics, One For All can be transferred by ingesting the DNA of the current holder.
All Might’s Decision
Recognizing Deku’s potential, All Might decides to pass One For All onto him. But before Deku can inherit it, he must first prove that his body is worthy of such an overwhelming power. All Might puts Deku through a ten-month training regimen, known as the ‘Aim to Pass: American Dream Plan,’ which involves cleaning up a beach covered in trash while building muscle and stamina. This training is symbolic it represents Deku’s journey from weakness to readiness, both physically and mentally.
The Moment of Inheritance
After completing the training, Deku is finally ready. All Might hands him a strand of his hair and instructs him to eat it. While the method is humorous, it is the key to transferring the Quirk. Once Deku consumes the hair, One For All begins to fuse with his body. However, he cannot use its full power immediately. His body is not yet strong enough to handle 100% of its energy without injury, which becomes a central struggle in his early journey.
Learning to Control One For All
Uncontrollable Power
At first, any attempt to use One For All causes massive damage to Deku’s body. In the entrance exam for U.A. High School, he uses all his power to destroy a giant robot and breaks his arm and legs in the process. Although this act impresses the judges and earns him a spot at U.A., it also underscores the dangers of using a power his body can’t yet support.
Over time, with guidance from mentors like Aizawa, Gran Torino, and All Might, Deku begins to understand the importance of using only controlled percentages of his power. He learns to use 5%, then 8%, and so on, creating combat styles like Full Cowling that allow him to distribute power evenly throughout his body.
The Evolution of One For All
As Deku continues to grow, One For All evolves. He begins to manifest the Quirks of its previous users, such as Blackwhip, Float, and Danger Sense. These new abilities open up new strategies and combat styles, making Deku a more versatile and unpredictable fighter. His journey becomes not just about physical strength, but also mastering a legacy of heroic power handed down over generations.

Unlike others who were born with their powers, Deku earns his through hard work, determination, and the trust of the greatest hero.

The Burden of Legacy
With great power comes immense responsibility. Deku doesn’t just inherit a Quirk he inherits the burden of continuing a fight against evil that began generations ago. He becomes the successor to All Might’s ideals and must learn to carry the weight of being a symbol of hope. His journey is not just about personal growth but about protecting others and shaping the future of hero society.
