#6 – Current Admiral Kizaru (Borsalino)
Fitting his title of admiral, Kizaru is one of the most powerful fighters within the World Government and the Marines.
The greatest aspect of Kizaru’s physical abilities is his immense speed and extraordinary reflexes, which is further enhanced by the light based powers of his devil fruit. Kizaru, in fact, possesses the power of the Pika Pika no Mi, a Logia-type Devil Fruit that grants him the powers of the element of light.
He is capable of moving and attacking at the speed of light, and all of his attacks are based on the element of light, such as firing energy blasts from his fingertips or feet with extreme accuracy and precision. His power is very destructive, causing huge explosions and can easily destroy buildings. He also has the ability to reflect himself, essentially moving from one location to the next at the speed of light. Due to this fruit’s power, Kizaru is possibly the fastest man in the world.
#5 – Former Admiral Aokiji (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.
#4 – Current WG Commander-in-Chief & Former Fleet Admiral 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.
