6-RYOKUGYU
Ryokugyu is a Marine Admiral. Not much is known about his abilities, anyway he was stated by Doflamingo to be a “true monster” in terms of power.
Ryokugyu has claimed to not have eaten in three years, a feat normally impossible for a human to do, and he still has the strength to move around and fight the Revolutionary Commanders.
7-FUJITORA
Fujitora is a Marine admiral. In terms of combat strength, he is considered to be one of the strongest fighters within the entire World Government structure.
Fujitora ate the Zushi Zushi no Mi, a Paramecia-type Devil Fruit that allows him the to manipulate gravity around a chosen location at will by sending gravitational forces. Fujitora can manipulate gravitational forces by channeling his Devil Fruit ability through his sword. He can send the gravitational forces by swinging or just simply moving his sword.
Fujitora has also shown mastery over two types of Haki: Busoshoku Haki and Kenbunshoku Haki, which he uses to compensate for his blindness in battle.
8-KONG
Kong is the World Government Commander-in-Chief. He was the Fleet Admiral of the Marines at the time of the Battle in Edd War twenty-seven years ago and at the time of Gol D. Roger’s execution twenty-four years ago.
Due to his muscles, his former rank in the Marines, and his numerous scars, he could be considered as one of the strongest marines ever, however he still has yet to reveal his powers in the series.
9-KUZAN
Kuzan is a former Marine admiral. He was nominated by Sengoku for the position of fleet admiral but after losing the position to Sakazuki, he resigned from the Marines and affiliated himself with the Blackbeard Pirates.
Kuzan has the powers of the Hie Hie no Mi, a Logia Devil Fruit that allows him to control, create, and become ice. In battle, he uses his ice powers to disable and immobilize enemies, freezing their bodies solid just by touching them, and threatening to shatter their fragile forms. This fruit is so powerful that his usage of it during his ten day battle with Akainu permanently changed the weather on one side of Punk Hazard, turning that side into a frozen wasteland.
Kuzan was considered to be a massive asset to the Marines, and his departure left a negative impact to their military strength. This was confirmed by the Gorosei calling him an ‘enormous power’ while discussing his affiliation with the Blackbeard Pirates, to the point of being visibly distraught while doing so.
10-SENGOKU THE BUDDHA
Sengoku the Buddha was the Fleet Admiral of the Marines pre-timeskip, succeeding Kong and preceding Akainu.
Alongside Garp and Tsuru, Sengoku is one of the most powerful Marines of his generation. Even without his Devil Fruit powers, Sengoku has enormous strength, enough to effortlessly hold down an enraged Garp with only one hand.
Sengoku ate the “Hito Hito no Mi, Model: Daibutsu”, a rarer-than-Logia Mythical Zoan-class Devil Fruit which allows him to turn into giant, living, Buddha-like golden statue, gaining an extreme boost in strength to match his size.
In this form Sengoku can launch golden shock waves to cause heavy and widespread damage to the enemies.
