The Marines are the world’s military sea force, tasked with law enforcement, international security, and military operations. They are present in all the seas around the world, as evidenced by their branch offices. However, the main focus of their assets is on the far more dangerous Grand Line. The Marines were one of the three great powers in the world, alongside the four Emperors and the seven Warlords of the Sea, who were later replaced by the SSG.

Due to their actions and roles overall, they are one of the main antagonist groups in the series. He primarily played this role in the Romance Dawn, Loguetown, Enies Lobby, Sabaody Archipelago, Marineford, and Return to Sabaody arcs, as well as the Warship Island, Goat Island, G-8, and Marine Rookie filler arcs, the fifth and eleventh movies, and the third, sixth, and tenth specials.
Due to this major role, most people love marnie officers and are very curious to know who the strongest marine officers are in one piece. Because of your curiosity in this article, we will give you the list of the Top 13 Strongest Marine Officers in One Piece.
So without further ado, let’s begin

13. Koby

Koby is a Marine Captain who trained together with Helmeppo under Vice Admiral Garp’s supervision. He is currently a member of the Marine special forces unit SWORD. He was formerly an involuntary pirate ship caretaker for the Alvida Pirates until he was liberated by Luffy, and he was the first person Luffy befriended on his travels.
In his first appearance, Koby lacked any fighting skills. According to Alvida, the only reason she kept him around was because he happened to be good at navigation. He gained some fighting skills when he trained under Vice Admiral Monkey D. Garp alongside Helmeppo.
Due to his harsh training regime under Garp as well as further training after two years, Koby possesses immense physical strength and speed. He has shown himself to be an excellent swimmer. He can move incredibly fast even when underwater, as he caught up to a torpedo within seconds. With his strength, he was capable of redirecting the large torpedo underwater with his bare hands.Furthermore he has some knowledge of swordsmanship, as he was seen practicing with Helmeppo and Bogard.
12. Smoker

Smoker is a Marine officer and the Commander of the G-5 Marine Base, following the treason of his former superior, Vergo. He was first introduced as a captain in Loguetown, where he made it his mission to capture Luffy, and was later promoted to the rank of commodore, due to the events in Arabasta. At some point during the timeskip, he was promoted to the rank of vice admiral.
Smoker is a formidable combatant, as, on top of his sheer strength, his Logia Devil Fruit abilities set him apart from most Marines of his rank. In Loguetown, he was on the verge of arresting Luffy during their first encounter, and would have succeeded had it not been for Luffy’s father, Monkey D. Dragon, interfering.Before Luffy came, it was said that pirate activity in Loguetown had dropped significantly since Smoker’s arrival, a testament to his competency.
As evident of his strong build, Smoker possesses incredible physical strength: during their confrontation in Loguetown, he was able to jump about two stories high without difficulty while holding Luffy and pin him down while he was unable to retaliate, a noteworthy feat, considering Luffy’s inhuman physical power.

11. Sentomaru

Sentomaru is the bodyguard of Vegapunk and is in command of the Marines’ Science Unit as its Captain. After the timeskip, he has become a full-fledged Marine officer. Due to his actions, he can be considered the secondary antagonist of the Return to Sabaody Arc.
Sentomaru claims to be a world-class guard. His fighting style is similar to that of Bartholomew Kuma’s, standing like a sumo-wrestler and striking with open-palm thrusts, which are enhanced through the use of Haki. This allows him to injure even Devil Fruit users as easily as normal people. He is faster than his size and build would suggest, being able to outpace Luffy’s normal running speed.
In addition, he appeared unfazed by Usopp’s giant smokescreen shortly beforehand. The fact that he was in charge of the Marines’ Science Unit suggests that he had great insight in that field of expertise.
10. X Drake

X Drake is the captain of the Marine Secret Special Unit SWORD. In order to go undercover as a pirate, he publicly defected from his position as rear admiral and founded the Drake Pirates. He is one of twelve pirates referred to as the “Worst Generation”, and prior to the two-year timeskip, had a bounty of 222,000,000.
As a former high-ranking Marine officer, Drake has a deep understanding of the workings of the world government and is able to use this knowledge to protect himself from danger and predict the movements of the Marines. He is also aware of the Pacifista and Vegapunk movements. His considerable knowledge may have contributed to his enormous bounty. He is also quite intelligent, interrupting Killer and Urouge’s battle because he knew that it would only draw more unwanted attention.
He is skilled enough that he was capable of interrupting the fight of two other Supernovas with just one move and has demonstrated physical strength to the degree where he was able to knock aside a “copy” of the Warlord of the Sea, Bartholomew Kuma.
9. Aokiji

Aokiji is a former Marine admiral and the first one to be revealed. He was nominated by Sengoku for the position of fleet admiral. However, after losing the position to Sakazuki, he resigned from the Marines. He is currently affiliated with the Blackbeard Pirates for unknown reasons.
While an admiral, Kuzan held power over thousands upon thousands of lower-ranked Marine personnel, his status being just below fleet admiral Sengoku’s. He could command whole fleets, have a say in the overall strategy of the organization, and issue special orders, like the enactment of a Buster Call on any island he deemed a threat, and delegate to lower-status government agents the same privilege. With his resignation, of course, came the forfeiture of any such powers.
Combat-wise, Kuzan is among the strongest characters to have appeared in the series, having been held with his fellow admirals as the “Greatest Military Power” that the World Government and Marine Headquarters could bring to bear. As one of the Marines’ chief assets, his departure left a notably detrimental impact on their force, as supported by the Five Elders’ calling him an “enormous power” in their dismay over Kuzan’s affiliation with the Blackbeard Pirates.

8. Tsuru

Tsuru is a veteran Marine Vice Admiral and an old associate of former Fleet Admiral Sengoku and fellow Vice Admiral Monkey D. Garp. As a veteran Vice Admiral from the same generation of Marines as Garp and Sengoku, Tsuru is one of the most prominent Marines in the world. She is well-renowned and recognised as a legendary figure by the likes of Franky and Usopp.
Even at her elderly age of 63, Tsuru was strong enough to strike intense fear into Doflamingo, who even becoming a Warlord of the Sea was an extremely powerful pirate, as he was quick to flee during her many pursuits of the Donquixote Pirates throughout the North Blue and despite his initial plans to reclaim Law from the Marines’ custody to use his powers to immortalize himself, Doflamingo quickly changed this plan upon seeing her battleship off the coast of Minion Island.
Several years later, when Doflamingo lost his title as a Warlord, he still showed respect for her, a stark contrast to his usual disrespect for other high-ranking Marines.
7. Ryokugyu

Ryokugyu is an admiral in the Marines. He attained his rank during the two-year timeskip, along with Fujitora, both filling the two admiral vacancies left by Aokiji and Akainu. His real name is currently unknown; “Ryokugyu” is his alias as an admiral.
As an admiral, Ryokugyu’s authority in the Marines is directly below the fleet admiral’s, holding power over any lower-ranked personnel, the ability to command whole fleets, have a say in the overall strategy of the organization, and to issue special orders, like enacting a Buster Call at any time while also granting those of lower status such ability. In general, Ryokugyu can be assumed to hold a great deal of military leadership and coordination skills to be seen as qualified for his rank and the authorities that come with it.
Ryokugyu, with the other admirals, is thought to constitute the World Government’s “Greatest Military Power” (i.e., the three strongest single combatants it can bring to bear), making him one of the world’s most powerful people. Both Ryokugyu and Fujitora were stated by Doflamingo to be known as “true monsters” in terms of strength.
6. Fujitora

Fujitora is an admiral in the Marines. He was conscripted through a World Military Draft during the two-year timeskip, being appointed to his rank (next to Ryokugyu) to fill the two admiral vacancies caused by Aokiji’s resignation and Sakazuki’s promotion. A proponent of “Moral Justice,” Fujitora notably spearheaded a campaign to abolish the Seven Warlords of the Sea system, which came to pass during the most recent Levely.
As an admiral, Fujitora has command over the thousands of Marines ranked beneath him, his status being just below that of a fleet admiral. Among other things, he holds the authority to call out battleships however he sees fit and to initiate a Buster Call on any island he deems to be a threat, as well as pass on to lower-ranking government agents the same privilege.
Concerning combat strength, Fujitora is thought with his fellow admirals to constitute the World Government’s “Greatest Military Force”, making him one of the world’s most powerful people. As noted by Doflamingo and himself, Fujitora and Ryokugyu are known as “powerful monsters” in the Marines.

5. Kong

Kong is the World Government’s Commander-in-Chief. He was the previous Fleet Admiral of the Marines at the time of the Battle of Edd War twenty-seven years ago. Some time after Gol D. Roger’s execution twenty-four years ago, Sengoku succeeded him as Fleet Admiral.
While he was the fleet admiral of the Marines, he had absolute control of the organization under the World Government. Now, as World Government Commander-in-Chief, he works for the World Government and possesses not only power over the Marines, but also authority over the government’s espionage agents, the Seven Warlords of the Sea, Enies Lobby, and the Cipher Pols.
According to the World Government hierarchy, his authority is second only to the Five Elders and Im. His political powers enable him to revoke any Warlord of the Sea title at any time, as well as be able to declare a Buster Call on any island he deems to be a threat. Aside from his political powers, his muscles and numerous scars suggest that he is physically strong and proficient in combat. However, he has yet to reveal his powers in the series.
4. Kizaru

Kizaru is an admiral in the Marines. After Aokiji resigned from the Marines and Akainu was promoted to fleet admiral, Kizaru is now the only remaining admiral from the previous trio.He was first mentioned by Nico Robin during the Straw Hats’ initial encounter with Aokiji. Kizaru is an incredibly tall, relatively slim man, roughly the same size as the other two ex-admirals, Aokiji and Akainu.
As an admiral, Kizaru ranks second only to Fleet Admiral Sakazuki (formerly Sengoku) in the Marines, holding power over the many thousands of junior personnel. His authority includes commanding entire fleets, influencing headquarters’ overall strategy, and issuing special-purpose orders like a Buster Call to destroy any island he deems a threat, or temporarily granting such privileges to others.
The admiral’s being able to exercise these authorities duly and efficiently bespeaks a great deal of military leadership and coordination skills on his part. As a combatant, Kizaru is among the strongest characters to appear in the story; he and his two admiral colleagues are crowned the World Government’s “Greatest Military Force”.
3. Sakazuki

Sakazuki, formerly known by his admiral alias Akainu, is the current fleet admiral of the Marines, succeeding the previous fleet admiral, Sengoku. During the first half of the series, he was one of the three admirals, as he was the last one to debut. Upon becoming fleet admiral, one of Sakazuki’s first decisions was to relocate Marine Headquarters to the New World in preparation for the New Pirate Age.
As fleet admiral, Sakazuki has total operational command of the Marines, with at present only six direct superiors to answer to: the World Government’s Five Elders and the Commander-in-Chief. On top of any prior-held authorities as admiral (e.g., issuing special orders like the enactment of a Buster Call on any island he deems a threat, at any time, and granting others such privilege).
Sakazuki can now fully lay down the organization’s strategy, decide tactics and set policy, discretionally assign and reassign forces to deploy globally in missions (including the admirals), promote or demote the lower ranks, and delegate any such powers as he sees fit; during the two-year timeskip, he exercised his authority to have the Marine Headquarters relocated to the New World as well as institute a global-scale draft.

2. Sengoku

Sengoku was a former fleet admiral of the Marines, succeeding Kong and preceding Sakazuki. Sometime during the timeskip, he became an Inspector General. He was also one of the major figures along with Whitebeard, Shiki, and Monkey D. Garp during the times when Gol D. Roger was still alive, and still continues to be in the present, even after his retirement from the Marines. He raised Donquixote Rosinante as his own son.
Due to his actions and his position in the Marines, he is one of the main antagonists of the Marineford Arc. As the former Fleet Admiral of the entire Marine force, Sengoku had absolute power over every action the Marines took, including summoning a Buster Call and granting or removing a Warlord’s title at any time, provided they met the criteria for either. The only ones that are above him are I (in secret), the Five Elders, and Commander-in-Chief Kong.
However, with his resignation came the loss of such authority. Gol D. Roger held high regard for him. After defeating a group of Marines, Roger commented that he was one of the two Marines that were worth his time, the other being Garp. Sengoku possesses a strong will as he was able to resist Luffy’s unconscious burst of Haoshoku Haki.
1. Monkey D. Garp

Monkey D. Garp was an extremely famous and powerful Marine Vice Admiral. He is the father of Monkey D. Dragon, the paternal grandfather of Monkey D. Luffy, and the adoptive grandfather of Portgas D. Ace. He was responsible for overseeing Ace’s birth and raising a young Luffy before entrusting them both to the Dadan family.
Garp is one of the major figures, along with Kong, Sengoku, Shiki, Silvers, Rayleigh, and Whitebeard, from the times when Gol D. Roger, the “Pirate King”, was still alive. His feats as a Marine soldier were met with immense notoriety and prestige, with his actions during one incident in particular bestowing him the title of Hero of the Marines. Notably, Garp was offered the rank of Admiral several times throughout his career, but he refused the offer of promotion every time.
Garp is easily one of the most powerful Marines and one of the strongest, if not the strongest, characters seen in the series. A testament to his strength is that he was one of the very few people to be considered a rival to the “Pirate King”, Gol D. Roger, and he was offered the rank of Admiral several times throughout his life. It should be noted that those who hold the rank of Admiral are regarded as the World Government’s “Greatest Military Powers” and are the strongest individual fighters within the World Government structure and the Marines.
