Dr. Kyudai Garaki, also known by his aliases Daruma Ujiko and Dr. Tsubasa, is the scientific mastermind and the most dedicated servant of the arch-villain All For One. For over a century, he has operated from the shadows, blending medical brilliance with moral depravity to transform the landscape of superhuman society. While the flashy battles between heroes and villains often take center stage, Garaki is the man who built the stage itself, providing the biological weapons and ideological framework that brought Hero Society to its knees.

The Architect of the Quirk Singularity Doomsday Theory

Long before he was a wanted war criminal, Kyudai Garaki was a brilliant, albeit controversial, medical researcher. Over seventy years ago, he proposed the Quirk Singularity Doomsday Theory. This hypothesis suggested that as Quirks are passed down through generations, they blend and grow in complexity and power. Eventually, these abilities would become so overwhelming that the human body would no longer be able to contain or control them, leading to a total societal collapse.

The scientific community of the time ridiculed Garaki, treating him as a paranoiac who sought to incite fear during an era that was finally finding stability. He was ostracized and vanished from the public eye. However, one individual saw the truth in Garaki’s warnings: All For One. The Demon Lord provided Garaki with the resources and the "raw materials" to prove his theory, cementing a bond of loyalty that would last for the next century. In our observation of the series' progression, the Quirk Singularity is no longer just a theory; it is the inevitable tragedy that characters like Eri and Tomura Shigaraki embody.

The Dual Identity of Jaku General Hospital

One of the most chilling aspects of Dr. Garaki is his ability to hide in plain sight. For decades, he maintained a public persona as the esteemed chairman of Jaku General Hospital. He was perceived as a philanthropic doctor dedicated to providing healthcare for the elderly and researching rare Quirk-related illnesses. This position was not just a cover; it was a strategic hub for his unethical experiments.

Hidden beneath the hospital was a sprawling, high-tech laboratory where Garaki conducted his most heinous work. He utilized the hospital’s morgue and patient records to source bodies for his research. This duality reflects Garaki's true nature: a man who can offer a kind smile to a patient while simultaneously planning to use their corpse as a vessel for a mindless super-soldier.

The Creation of the Nomu: Bio-Engineering Horrors

Dr. Garaki is the undisputed father of the Nomu, the bio-engineered monsters that have plagued the Pro Heroes since the USJ Incident. The process of creating a Nomu is a testament to Garaki's surgical genius and complete lack of empathy. By taking the deceased (or near-deceased) and pumping them full of multiple Quirk factors, he creates "empty vessels" capable of wielding powers that would normally kill a human.

The Classification of Nomu

Through the series, we see the evolution of Garaki's "children":

  • Lower-Tier Nomu: Mindless drones used for cannon fodder.
  • Middle and Upper-Tier Nomu: Possessing multiple quirks and enhanced physical durability, capable of challenging top heroes.
  • High-End Nomu: Garaki’s masterpieces. These creatures, such as Hood, possess sentience and can think strategically during combat. The High-End Nomu represent the pinnacle of his biological tampering, requiring months of "fermentation" in specialized tanks.

The most tragic example of Garaki's work is Kurogiri. It was Garaki who took the body of Oboro Shirakumo, a promising UA student and the best friend of Shota Aizawa and Present Mic, and reanimated him into the League of Villains' primary transporter. This act highlights that for Garaki, human life and memories are nothing more than data points to be overwritten for the sake of his master’s vision.

The Dr. Tsubasa Connection: A Dark Link to Izuku Midoriya

One of the most shocking revelations for the My Hero Academia fanbase was the confirmation that Dr. Garaki is the same doctor who diagnosed a young Izuku Midoriya as Quirkless in Chapter 1. Under the name Dr. Tsubasa, he sat across from Izuku and Inko Midoriya, bluntly telling the boy to "give up."

While many initially saw this as a minor background character, the retroactive realization of who Garaki really is adds a layer of malice to that scene. Garaki pointed to the double-jointed pinky toe as proof of Izuku's status. However, knowing his history of stealing Quirks for All For One, a popular and haunting fan theory suggests that Izuku may not have been born Quirkless, but was instead "harvested" by Garaki. While this remains unconfirmed in the manga canon, the fact that he was the gatekeeper of Izuku's despair proves his integral role in the series' inception.

Furthermore, the winged Nomu that grabbed Izuku during the Hosu City arc was later revealed to be the grandson of Dr. Garaki—the same boy who bullied Izuku alongside Bakugo. Garaki had turned his own family member into a Nomu, showcasing a level of depravity that even other villains find repulsive.

The Life Force Quirk: The Secret to Immortality

How has Dr. Garaki remained active for over 120 years? The answer lies in his Quirk, Life Force. This ability doubles the user's lifespan at the cost of physical mobility. In a move of absolute devotion, Garaki gave his original Quirk to All For One and currently utilizes a duplicated version of it.

This duplicate Quirk is the only thing keeping him alive and "youthful" (by 120-year-old standards). During the Paranormal Liberation War, when Eraser Head used his Quirk to nullify Garaki’s abilities, we saw the doctor’s true form: a shriveled, decrepit man whose body instantly caught up with his chronological age. This moment of vulnerability was a rare sight for a character who had spent decades manipulating the very fabric of life.

Personality: The Cowardly Devotee

Unlike the bravado shown by Shigaraki or the charismatic evil of All For One, Dr. Garaki is fundamentally a coward. When confronted directly by heroes like Mirko or Present Mic, he panics, shrieks, and begs for mercy. He is a "guy in the chair" who thrives when he has layers of protection—be it concrete walls or High-End Nomu.

However, his cowardice is eclipsed by his fanatical loyalty. He views All For One not just as a boss, but as a god who validated his existence when the rest of the world cast him out. His relationship with Tomura Shigaraki was initially skeptical; he viewed the young man as an unproven brat. But after Shigaraki proved his "destruction" was absolute during the battle with the Meta Liberation Army, Garaki committed all his resources—including the perfected Quirk-transplanting procedure—to making Shigaraki the ultimate vessel.

The Scientific Arsenal: Beyond the Nomu

Garaki’s contributions to the villainous cause extend beyond biological monsters:

  1. Quirk Duplication: He developed the technology to scan, store, and duplicate Quirks, allowing All For One to build a massive library of powers.
  2. Quirk-Destroying Bullets: While Overhaul and the Shie Hassaikai created the original bullets using Eri’s DNA, Garaki was able to reverse-engineer and mass-produce them without the original source, demonstrating a level of technical prowess that rivals the best hero-tech developers.
  3. Body Modification: He performed the agonizing surgeries on Shigaraki and Dabi, allowing them to withstand the self-destructive nature of their own amplified Quirks.

What is Dr. Garaki's Current Status?

Following the raid on Jaku General Hospital in the Paranormal Liberation War arc, Dr. Garaki was finally apprehended. Despite his capture, the damage he inflicted on the world is largely irreversible. The "Central Hospital" and other facilities were left to deal with the aftermath of his experiments, and the Quirk-destroying drugs he helped perfect continued to be a factor in the Final War.

Even in custody, Garaki remains unrepentant, viewing the chaos outside as the ultimate validation of his Quirk Singularity Theory. He is a man who won the ideological war, even if he lost his freedom.

Summary of Dr. Garaki's Role in MHA

Dr. Kyudai Garaki is more than just a mad scientist; he is the structural foundation of the series' antagonism. By providing the means for All For One to survive, for Shigaraki to evolve, and for the Nomu to terrorize society, he proved that a sharp mind and a lack of conscience can be more devastating than the most powerful combat Quirk. His legacy is one of stolen lives, shattered families, and a world teetering on the edge of a biological apocalypse.

FAQ: Common Questions About Dr. Garaki

Did Dr. Garaki steal Deku's Quirk?

While it is a popular fan theory due to Garaki being the doctor who diagnosed Izuku, there is no official confirmation in the manga that Izuku originally had a Quirk. The narrative currently maintains that Izuku was born naturally Quirkless.

Is Dr. Garaki still alive?

Yes, as of the latter stages of the manga, Dr. Garaki is imprisoned. However, without his Life Force Quirk being active (due to suppression or aging), he is in a very frail state.

Why did he help Dabi?

Garaki and All For One took interest in Toya Todoroki (Dabi) after his "death" at Sekoto Peak because of his incredible firepower. Garaki used regenerative tissue to patch Toya's body together, though he initially viewed Dabi as a "failed experiment" because his body couldn't handle his own flames.

What is the Quirk Singularity Theory?

It is the belief that as Quirks continue to mix through reproduction, they will become too powerful and complex for the human body to handle, eventually leading to a point where humanity can no longer control its own evolution, resulting in destruction.

Who voiced Dr. Garaki?

In the Japanese version of the anime, he is voiced by Minoru Inaba. In the English dub, he is voiced by Mark Stoddard.
