Here is everything you need to know about the strongest male marines in One Piece.
Koby
Koby, also known as the Hero, is one of the members of the secret navy unit, SWORD. The fact that he has been enlisted in this secret unit is a testament to his strength. Koby is an underling of X-Drake, which is close to showing that he is strong indeed.
Kobe is an excellent user of Haki as well. He most likely possesses both Armament and Observation Haki. He was heavily involved in the Rocky Port Incident. Currently, he has been abducted by the Yonko. In the future, he’s only going to get stronger.

John Giant
John Giant is a Vice Admiral of the Navy and was introduced during the Marineford arc for the very first time. As his name indicates, he is a giant from the land of Elbaf. He found his way to the Navy thanks to Mother Carmel.
Despite his sad past, he continues to fight for the Marines, and in the Paramount War. That said, John Giant possesses the strength that the Navy has coveted for centuries. As a Vice Admiral, he possesses the ability to use both Armament and Observation Haki.
Momonga
Momonga is a powerful Vice-Admiral, just like Onigumo. He 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 just like Onigumo. He knows both Armament and Observation Haki, which is one of the many reasons why he survived in the Calm Belt.
Smoker
Smoker is one of the Vice-Admirals of the Marines and rose to this rank after the events of the Marineford War. He 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.
Smoker has the ability of the Logia-type devil fruit Moku Moku no Mi, which allows them to control smoke and transform it at will. He can also use Armament and Observation Haki, adding to his power.
Sengoku
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, 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.

Monkey D. Garp
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.
