Typically, the most powerful and notable figures in One Piece are the many pirates of the world. This is due to a whole host of reasons, particularly owing to their incredible Devil Fruit powers, which are often compounded with their unparalleled prowess in the various forms of Haki.
However, despite pirates often belonging at the top of the most powerful characters’ lists, they aren’t the only ones to be considered the strongest in the One Piece world. So, in this article, let’s go over the strongest characters in the world who aren’t pirates to see what role they could play in the Final War of the series.

Sengoku Was Once One Of The Strongest Characters
Designation: Former Fleet Admiral
In the entire institution of the Navy, there are only two characters who stand among the titans of the old generation of pirates. One of them is Sengoku, a character so powerful that Roger himself considered him an equal and named him one of the only two Marines who could actually stand a chance at taking him on in a battle.
As one of the only confirmed Marines to have the ability to wield all 3 Haki types, Sengoku’s strength through these means alone sets him apart as being one of the strongest characters in history, but when seen in conjunction with his Mythical Zoan Devil Fruit, his strength becomes even more terrifying. Although he is old and far past his prime now, he remains a legend in the world.

Fujitora Has Some Of The Best Observation Haki
Designation: Navy Admiral
After the events of the legendary Marineford War, the Navy underwent a significant restructuring, which saw the departure of Aokiji and the promotion of Akainu to Fleet Admiral. Due to this, there were two vacant Admiral spots, which were then filled by Aramaki and Issho, the latter of whom proved to be insanely powerful.
Issho, better known as Admiral Fujitora, has some of the best Observation Haki in the series, as he was able to use it to see and fight despite being blind in both of his eyes. On top of this, his incredible gravity-manipulating Paramecia fruit gave him one of the most broken abilities in the series, marking him among the greatest forces allied with the World Government.

Kizaru Is The Fastest Character Of All Time
Designation: Navy Admiral
Of the 3 original Admirals in the story, Kizaru is the only one to have retained his position after the Summit War, and this has to do with the fact that he is one of the greatest assets that the World Government has at its disposal. Using his Logia Devil Fruit, which allows him to become and manipulate light, alongside his Haki, Kizaru was a terrifying foe for anyone to face.
During the events of the Sabaody Archipelago arc, Kizaru’s interference was what defeated the Straw Hats and led to the time skip. Moreover, during the events of the Egghead Island arc, Kizaru was personally chosen to act as security for St. Jaygarcia Saturn, which alone proves his importance and strength in the World Government.

St. Figarland Shamrock Leads The Holy Knights
Designation: Supreme Commander of the Holy Knights
One of the greatest One Piece theories was confirmed early on in the Elbaf arc, where it revealed the truth of Shanks having an evil twin brother who worked for the World Government. This was St. Figarland Shamrock, and his brief time in the arc truly did go to show how strong he was and proved him to be one of the major players in the Final War of One Piece.
Very little is known about this man, but seeing as how he leads a group which seems to rank even higher than the Admirals, it wouldn’t be too far to assume that his strength is equal to one. Some fans even believe that, owing to his lineage and relation to Shanks, he is also a wielder of Advanced Conqueror’s Haki, which would make him stronger than the regular Admirals.
6
Garp Is The Single Greatest Marine In History
Designation: Former Vice Admiral
Out of every character in the series who is allied with the World Government, none are even nearly as iconic as Garp. Although he never went past the rank of Vice Admiral, Garp did this by choice since it allowed him to do whatever he wanted, and his strength was so valuable to the entire organization that they allowed him to carry on as he wished.
In his prime, it’s fair to say that no one was on the same level as Garp, as he was an equal to the strongest pirates of the old generation, Roger and Xebec, whose strength still hasn’t been matched to this day. However, even in his old age, Garp’s physical prowess allowed him to take on the forces of the Blackbeard Pirates by himself, proving that he has surpassed his own legend.
5
Akainu Holds The Highest Power In The Navy
Designation: Fleet Admiral
It has often been stated that the most dangerous man in the entire One Piece story is Akainu. Starting his journey in the story as one of the Admirals, he would eventually defeat Aokiji in a 10-day-long battle to become the next Fleet Admiral of the Navy, which has given him some of the highest power and authority in the entire world.
Aside from this, he is stated to have the single most offensively-potent Devil Fruit in the entire story, using which he was able to kill many notable characters, such as Whitebeard and Ace. Most fans believe that he must also be a user of Conqueror’s Haki, and if true, it would cement him as the most powerful Marine of the modern era and the strongest of all time after prime Garp.
4
Loki Has Many Of The Strongest Powers In The Setting
Designation: Prince of Elbaf
Elbaf has always been steeped in mystery and intrigue, particularly due to the strength of the general population of Giants there. Due to this, it comes as no surprise that this island has one of the strongest Devil Fruits in the entire setting in the Ryu Ryu no Mi, Model: Nidhogg, as well as the legendary weapon Ragnir.
Loki is currently the character who has both of these overpowered things in his possession, making him a towering powerhouse whose strength is likely even above Luffy’s own in the current setting. This, alongside his uncanny natural talent of wielding Advanced Conqueror’s Haki without any prior training, make Loki one of One Piece’s strongest figures.

The 5 Elders Are Imu’s Greatest Generals
Designation: The Highest Authority
It’s known that the Final War of One Piece is destined to be a legendary conflict that will involve just about every inhabitant of the world. The main opposing force here is set to be Imu, and his greatest generals, who will enforce his will to maintain the order of the world, are the 5 Elders.
These characters are the highest authority in the entire World Government and are considered to be the outward ruling face of the organization. As such, they have been gifted with some incredible powers by Imu in the form of their Yokai transformations, which were so strong that they withstood attacks from Luffy’s Gear 5 state and utilized incredible powers and Haki abilities.

Monkey D. Dragon Is The Biggest Wildcard Of Them All
Designation: Leader of the Revolutionary Army
One of the biggest mysteries in the entire One Piece franchise is someone who was revealed in its earliest days. Monkey D. Dragon is Luffy’s father and the biggest enigma in the entire series, since his appearances throughout the story have been incredibly vague and his power is thought to be one of the greatest that the franchise has ever seen.
However, this is purely conjecture from the fans, though it is based on some interesting evidence. It seems that Dragon is always followed by a storm of some kind, leading to the popular theory that his Devil Fruit ability is that of a storm Paramecia, a wind Logia, or a Rain God Mythical Zoan. When his combat debut is made, Dragon will confirm every fan theory about his strength.

Imu Is Currently The World’s Strongest Character
Designation: Ruler of the World Government
It comes as no secret that the ultimate villain of One Piece is also the most powerful non-pirate character in the story. As the man ruling over the world for the past 800 years, Imu was the one who defeated Joyboy during the events of the Void Century and laid the foundations for the World Government to enforce the racist rule of the Celestial Dragons on the rest of the world.
In his fight against the heroes in the Elbaf arc, Imu showed prowess with his Devil Fruit and Haki that had seldom been heard about or seen before. Not only is Imu the strongest non-pirate character we have seen in the series so far, but he is the strongest character in the entire story so far, and will likely remain so until Joyboy’s official debut.
