10 Strongest One Piece Doctors, Ranked: From Chopper to Law

In the world of pirates, not every individual is a fighter. Not all sailors on the high seas yearn for battle; some have roles aboard ship that are more supportive than aggressive. Medical personnel like doctors and nurses often fit this description. Yet, among these pirate medics, there are those who do engage in combat, with some even being the most formidable members of their crews.

As an observer, I notice that several medical professionals, such as Tony Tony Chopper and Trafalgar D. Water Law, utilize their healing abilities in the heat of battle. It can be challenging to pinpoint the exact level of power these characters possess, but their roles within their crews and the reputation of those crews offer some insight. Characters like Kureha undoubtedly hold significant power, but those who aren’t pirates or aren’t inclined towards combat are not included in this discussion. The Doctorine may be incredibly strong when it comes to managing unruly patients, yet she rarely engages in direct confrontations herself.

In the world I’ve found myself in, characters such as Masked Duce appear to be formidable, but due to scarce canonical data, it’s challenging to fully gauge their capabilities. Interestingly, within the Marines, there are merely two recognized doctors, and none among the Revolutionary Army. This suggests that the pool of physician pirates with notable strength is relatively large. Despite not always being the most powerful individuals in a crew, doctors remain indispensable for their crucial role in providing medical care.

Hiriluk Was a Theif Before His Change of Heart

Hiriluk lacks any extraordinary physical abilities, but he’s surprisingly resilient in cold conditions and has a knack for surviving his own experiments. His unusual talent of putting his terminal illness into remission during his youth hints at an exceptional quality. Moreover, he was able to endure the blasts he triggered and cope with his enigmatic terminal illness. Nevertheless, his demise occurred when the bombs he attached to himself detonated, and it’s believed that the Amiudake mushroom provided by Chopper would have eventually led to his death as well.

Despite waving a pirate flag, Hiriluk didn’t embody the typical pirate persona, but instead excelled as a cunning thief in his younger days. His thefts ceased not due to incapacity, but rather a shift in morality. Notably, Hiriluk was proficient with various firearms and had a knack for handling explosives. However, his actions caused significant harm, making him far from an effective or compassionate doctor.

Zombies Follow Hogback’s Orders

Hogback, a highly skilled surgeon, has an unusual disdain for all his patients. He entered the field of medicine primarily for financial gain and recognition, which wouldn’t have been an issue if he hadn’t allowed himself to be manipulated by Gecko Moria. Using his abilities and this partnership, Hogback brought Victoria Cindry back to life, despite her having no affection for him during her lifetime. The medical community was shocked when Hogback suddenly vanished from the scene.

In the service of Moria, Hogback performed surgeries on dead bodies to produce perfect vessels for Moria to insert shadows into. Beyond being one of the Mysterious Four, Hogback plays a crucial role in assembling Moria’s undead army. Although he lacks personal combat abilities, Hogback commands a horde of zombies that follow his instructions. This may not be a conventional power, but it certainly makes dealing with Hogback challenging during battles.

Gerd is an S-Class Mercenary with a Giant Axe

In the anime so far, Gerd hasn’t had many opportunities to demonstrate her skills as a doctor or her prowess as a physician, but there are some logical inferences we can make about her. Firstly, considering she takes care of the New Giant Warrior Pirates, a rather rowdy crew, it’s clear she possesses the competence necessary to keep them healthy and fit. On top of that, given her status as a giant, she naturally possesses greater physical strength than most individuals at sea.

Gerd, too, wields a massive axe, signifying her readiness for combat. Given that giants age at a slower pace compared to other species, it implies that she’s had ample time honing her fighting skills. Her prowess in battle was recognized by Buggy’s Delivery Service, earning her an S-Class mercenary ranking. As the story unfolds further, we can expect Gerd to display more of her power, but it’s worth noting that she has a history with Big Mom as childhood friends.

Aladine is In Charge Now That Jinbe is Gone

As the physician for the Sun Pirates, Aladine still held the role of first mate during Jinbe’s tenure as captain. Upon Jinbe’s departure to join the Straw Hat Pirates, Aladine took charge of the remaining crew. To ensure their safety, Aladine needed to be quite formidable. He has been a part of the Sun Pirates since Fisher Tiger was captain and previously served as a soldier for the Ryugu Kingdom in the Fish Man Islands.

Aladdin possesses sufficient strength to confront one of the Big Mom Pirates, though he may not be among the Sweet Commanders. Nevertheless, he is an important member within their ranks, having demonstrated his abilities numerous times throughout his past and recent conflicts. It’s likely that Aladdin spends less time now serving as a doctor due to changes in ship position, but he should still retain the medical skills he has honed over time.

Crocus Lives Inside an Island Whale

As a passionate history enthusiast, let me share a fascinating tale about the legendary pirate Gol D. Roger. When he was diagnosed with an incurable disease, he embarked on a quest to find the world’s greatest doctor, Crocus, to sail alongside his crew. Although Roger had spent most of his life as a lighthouse keeper, Crocus was renowned for his exceptional medical skills, making him the ideal choice to help manage Roger’s illness.

Throughout their journey to Laugh Tale, despite numerous conflicts that arose along the way, Crocus ensured that Roger remained in peak fighting condition. This unwavering dedication by both Roger and Crocus played a significant role in shaping the course of pirate history as we know it today.

It’s clear from the Edd War and Roger’s ascension to the Pirate King, along with its aftermath, that Crocus possessed some formidable strength. Not every member of the Roger Pirates needed to be incredibly powerful, so it’s plausible that Crocus generally avoided engaging in combat. Nevertheless, Crocus was a crew member and even resided at Reverse Mountain – a region known for its frequent conflicts.

The Ten Titanic Captains Need Power to Keep Their Following

Other people rely on Doctor Q to treat their injuries, but it seems like he’s more focused on causing illness rather than healing. Given his nickname, Sick Sick Fruit, this isn’t too surprising. However, despite being born with an illness himself, Doctor Q has managed to stay healthy enough to work alongside his crew members. Remarkably, he appears to be quite resilient and has a greater endurance than one might initially expect.

During the Summit War, Doctor Q demonstrated an impressive strength capable of inflicting harm on the injured Whitebeard. As one of the Ten Titanic Captains, he commands a significant following within the Blackbeard Pirates. Despite being unable to walk unaided, he wields a massive scythe with agility. While his physical prowess is notable, it’s not where Doctor Q truly excels. Leveraging his expertise in chemistry and the devastating diseases conferred by his Devil Fruit, he also crafts explosive bombs, making him a formidable adversary.

Chopper’s Passion Fuels His Need to Protect the Straw Hat Pirates

In the anime, fans observe Chopper becoming progressively stronger since he belongs to the compact Straw Hat Pirate team, where every member is a fighter. As he engages in more battles, he gains confidence, even when fearful of a fight. Remarkably, this determination propels him to challenge Emperors. Moreover, his Rumble Balls grant him the ability to creatively control his Devil Fruit powers.

Chopper, an extraordinary medical professional, excels at discovering remedies for diseases even amidst the heat of battle, and he encounters numerous adversaries during these battles too. However, Chopper’s primary interest lies in finding cures for all diseases. Despite this, he consistently strives to improve his own strength. This was evident when he managed to master his monster form following the time skip. Although it has been a while since he received an upgrade of his own, Chopper continually uses his abilities to create more effective Rumble Balls to aid in combat.

The Red Hair Pirates Are Small and Unquestioned

Among all individuals on this list, Hongo stands out as the most enigmatic figure. Initially, he made an appearance early in the narrative, merely blending into the crowd of Red Hair Pirates during their stay at Foosha Village. Since then, only a few instances have shown him in the manga, yet these instances provide little insight into his personality or background. What we do know is that Hongo holds a significant position within the Red Hair Pirates and was the one who reminded Shanks of his territorial matters. It can be inferred that Hongo maintains oversight over Shanks’ domains.

During the Summit War, Shanks’ mere presence with his team was enough to bring the conflict to an end, even though they were relatively small and preoccupied with Kaido. Their appearance was so intimidating that it made the Marines retreat. Hongo, without a moment’s hesitation, moved among them, suggesting he is another influential figure. Even though he may just be a doctor on board, being part of Shanks’ crew, which belongs to an Emperor, increases the likelihood that Hongo holds significant power.

Mythical Zoans Have Many Uses

Marco, also known as Phoenix, was previously the top commander in the First Division of the Whitebeard Pirates. Following their loss at Marineford, he assumed leadership of the pirate remnants during their futile quest for revenge. Despite the Whitebeard Pirates suffering defeat, Marco’s strength did not diminish; instead, it grew to a point where he could confront high-ranking Marines like Monkey D. Garp and Marine Admirals fearlessly. This formidable power enables him to safeguard Whitebeard’s remaining treasure, Sphinx Island.

In his medical practice, Marco possesses an uncommon shortcut known as the Bird Bird Fruit, Model: Phoenix. This unique artifact grants him the ability to generate revitalizing flames, which serve not only to heal himself but also others in need. Beyond providing aid, these self-rejuvenating flames make him a formidable adversary on the battlefield due to his perpetual self-healing abilities. In the Raid on Onigashima, Marco proves an indispensable ally, offering robust defense against illnesses and reinforcing the team with his impressive strength.

Law Faced Emperors With His Allies

In a failed effort to save his sister from Amber Lead Disease, Law studied medicine. As a child, he picked up fighting skills while following Donquixote Doflamingo. These skills were honed over time. Now, Law primarily employs his Devil Fruit powers in combat. He also uses his cursed sword, Kikoku, to complement his Devil Fruit abilities. This combination has proven useful in the majority of his battles.

The employment of the Devil Fruit by Law ultimately leads him to summon its powers. With these newfound abilities, he manages to challenge Big Mom single-handedly, backed only by Eustass Kid. Although they don’t possess the same level of strength as Monkey D. Luffy, they are undeniably formidable pirates. However, Law succumbs to Marshall D. Teach’s surprise attack on Winner Island. Despite suffering defeat and losing his ship and a significant number of crew members, he manages to wound Blackbeard with relative ease.
