The Marines are a powerful organization in One Piece and they are known to be the World Government’s military face. Responsible for upholding justice, the Marines are often pitted against the pirates. The population of such pirates boomed after the death of the Pirate King, Gol D. Roger, and the beginning of the Great Pirate Era.
Over the years, some of the most incredible talents in One Piece’s world have risen through the ranks of the Marines. At the same time, some terrific additions have been made over the course of the series’ run, making them as powerful as they are today.
15 Onigumo Is A Powerful Marine Vice-Admiral
Onigumo is one of the Vice-Admirals of the Navy who was properly introduced to the fans during the Paramount War saga of the story. As a Vice-Admiral, Onigumo is quite powerful and knows two types of Haki, both Armament and Observation Haki.
Onigumo also has a Devil Fruit power that allows him to produce hairy arms from his back that turn him into a spider. With this power, he uses his famous Eight-Sword Style, as seen during the Marineford arc of the story.
14 Momonga Survived The Calm Belt
Momonga is a powerful Vice-Admiral, just like Onigumo, but one that fans have seen slightly more of. Momonga is a user of some of the Rokushiki arts, as seen during the Marineford arc. His skill with a sword is known to be great enough to push back some pirates from the New World.
Momonga is also an exceptionally skilled user of Haki and just like Onigumo, he knows both Armament and Observation Haki, which is one of the many reasons why he survived in the Calm Belt for quite a while.
13 Chaton Is A Strong Marine
Another Vice-Admiral, Chaton is a character that fans know little about. Being a Vice-Admiral, Chaton is strong enough to use the two basic Haki types but he is much more special than that.
During the timeskip, Chaton was being considered for the position of Admiral that was vacated by Akainu and Aokiji. This is a clear indication that his level of skill is certainly above the likes of the regular Vice Admirals, and is one of the many reasons why he is considered to be very powerful.
12 Momousagi Is As Strong As Chaton
Just like Chaton, Momousagi was also considered for the position of Admiral during the two-year timeskip. Although Momousagi wasn’t selected for the spot, the fact she even contended for this position proves that she is quite strong.
Momousagi’s abilities remain unknown, however, she is definitely a skilled user of Haki of at least two types, just like all the other Vice-Admirals out there. Her true abilities haven’t been seen in battle so far, however, she certainly ranks among the very strongest Marines in One Piece.
11 Smoker Rose Through The Ranks Quickly
Smoker is one of the Vice-Admirals of the Marines, and rose to this rank after the events of the Marineford War. Introduced back in Logue Town, Smoker was a Marine Captain who held the reputation of never letting a pirate escape from his grasp. After Luffy’s successful escape, he set out for the Grand Line and in doing so, gained a lot of power.
Smoker has the ability of the Logia type devil fruit Moku Moku no Mi, which allows him to control smoke and transform into it at will. He can also use Armament and Observation Haki, adding to his power.
10 X Drake, Member Of The Secret SWORD Force
X Drake is known to be one of the strongest pirates under Kaido; however, he’s actually a member of the Marines and serves as a Captain of the SWORD — the Marines’ Special Forces unit. Drake is currently fighting against Kaido and Big Mom’s forces on Onigashima alongside Luffy.
In terms of power power, Drake is a fearsome fighter who holds the rare ability of the Ryu Ryu no Mi, Model: Allosaurus. He’s also a capable user of Haki, as expected of someone with his rank.
9 Sentomaru, One Of The Best Haki Users In The Marines
Making his debut during the Sabaody Archipelago arc, Sentomaru gained an official Marine rank after the two-year timeskip. Although his exact rank remains unnamed, he’s certainly one of the higher-ranking officials, as expected of someone of his strength.
Before the timeskip, he was revealed to be a very capable user of Ryou, which is an advanced form of Armament Haki. Over the years, his skill is likely to have improved, making him even more powerful now.
8 Ryokugyu, A New Admiral Of The Marines
After the Paramount War, the Marines required additional manpower to fill the two vacant positions left by Akainu and Aokiji. Ryokugyu was chosen as one of the members of the Three Admirals, through a World Military Draft.
Unfortunately, he hasn’t been seen in action yet. However, being an Admiral automatically makes him one of the strongest people in the story. Interestingly enough, he hasn’t eaten anything for three years, implying that he possesses a power that doesn’t require him to eat. It may be interesting to see where this power comes from in the future.
7 Fujitora Joined The Marines Alongside Ryokugyu
Fujitora made his debut in the Dressrosa arc as an Admiral of the Marines. Just like Ryokugyu, he was chosen for the position of an Admiral through a World Military Draft.
According to Donquixote Doflamingo, Fujitora is known to be a monster throughout the world. He wields the power of the Zushi Zushi no Mi, a formidable Devil Fruit which allows him to control gravity at will. Fujitora is also a capable user of Observation Haki, as seen during his fight against Sabo.
6 Kizaru, A Fearsome Admiral
One of the Three Admirals introduced before the timeskip, Kizaru is an incredibly powerful fighter. He possesses the power of the Logia-Type Pika Pika no Mi, which allows him to turn into light and attack with it according to his will.
This Devil Fruit power is one of the most fearsome in the entire story. When coupled with his great mastery over two Haki types, he’s a force to be reckoned with. Kizaru could hold off Marco during the Marineford War, and even fight Whitebeard to an extent.
5 Aokiji Was Almost On Par With Admiral Akainu
Aokiji was an Admiral of the Marines until after the events of the Paramount War. With the era changing, Sengoku deemed it best to pass on the mantle of the Fleet Admiral to him.
However, failing to defeat Akainu led to him leaving the organization. Nonetheless, Aokiji was a force to be reckoned with and could take on Akainu in an even battle for 10 days. His power of the Hie Hie no Mi made him a threat to anyone in the world, and his control over Haki was incredibly refined.
4 Kong Is Among The Strongest Marines
Kong was the former Fleet Admiral of the Marines during the era of the Pirate King, Gol D. Roger. The likes of Sengoku and Garp worked under him, which just goes to show that he must’ve possessed tremendous strength himself.
Fleet Admiral is a position that not just anyone can attain. So far, only Sengoku and Sakazuki have obtained this role and both are strong enough to be considered among the top tiers of the One Piece world. In the Whole Cake Island arc, Mother Carmel claimed that if Big Mom joined the Navy, she was so strong that she could even end up becoming a Fleet Admiral, which gives fans an idea of how strong Kong must’ve been back in the day.
3 Sakazuki, The Strongest Active Marine Right Now
Formerly known as Admiral Akainu, Sakazuki is currently the Fleet Admiral of the Marines, and acquired this position after beating Aokiji on Punk Hazard. As the Fleet Admiral, it goes without saying that he’s incredibly powerful.
Sakazuki has the power of the Magu Magu no Mi, which allows him to create magma and transform into it. During the Paramount War, Sakazuki could fight against Whitebeard for an extended period of time and even inflicted severe injuries on him.
2 Sengoku, The Former Fleet Admiral
Prior to the events of the Paramount War, Sengoku was the Fleet Admiral of the Marines. This posting alone implies that he was monstrously powerful. With the power of the Mythical Zoan Hito Hito no Mi, Model: Daibutsu, Sengoku could match even the strongest of pirates in his prime.
He’s also the only Marine so far to possess all three types of Haki. According to Roger, he gave him a great challenge, meaning the two were close in strength.
1 Monkey D. Garp, The Strongest Marine
Luffy’s grandfather, Garp rules supreme as the strongest Marine in One Piece. Although just a Vice-Admiral, Garp’s strength surpasses that of all the Admirals in the story, as evident from the fact that he could fight the likes of Roger on an equal footing.
Garp’s control over Armament and Observation Haki made him a threat to any pirate in the world. His actions earned him the title of the “Hero of the Marines,” which is fully deserved considering his legacy.
