10T Bone

A Veteran Whose Dedication To Justice Never Faded

Debuting during the pre-time skip era,Vice Admiral T Bonebattled Zoro when the pirate and his comrades were en route to Enies Lobby tosave Robin from the hands of CP9. Despite acknowledging Zoro to be a fearsome foe, T Bone was ready to face him nonetheless to protect his subordinates and due to his moral code as a Marine.

T Bone’s moral code was present during many of his years in the service, as he even became overly stressed about his subordinates' relatively unimportant problems. Unfortunately, T-Bone died at the hands of a civilian, the very people he swore to protect.

9Issho (Fujitora)

The Blind Admiral Who Sees The Flaws Of The World

Before being conscripted through a world military draft to become an Admiral,Fujitoraserved as a defensive military chief in a kingdom in the Grand Line. As he was recently drafted, Fujitora hasn’t served with the Marines for long, causing many to wonder how he managed to become an Admiral so quickly.

With his proactive nature, Fujitora has achieved major accomplishments since joining the Marines, such as the abolition of the Warlord system. With his “Humane Justice” motto, the now 54-year-old Admiral prioritizes saving people over apprehending pirates, a habit that frequently puts him and Akainu at loggerheads.

8Sakazuki (Akainu)

A Marine Whose Ruthless Determination Has Withstood Generations

Particularly with his usually overbearing demeanor, it’s interesting to see that the now-Fleet AdmiralAkainuis even younger than Admiral Kizaru. At 55 years of age, Akainu holds the mantle of Fleet Admiral and possesses the Devil Fruit with the most offensive capabilities in the series.

Considering he was present in Ohara over two decades ago and had reached the rank of Vice Admiral even then, Akainu’s long-standing service to the Marines is apparent. With his unique and extreme form of justice, the current Fleet Admiral doesn’t seem like he’ll be toning down with age anytime soon.

7Brannew

An Experienced Officer Trusted With The Marines’ Greatest Bounties

As a Commodore,Brannewisn’t as high-ranking as many others his age, but he is in charge of placing bounties on pirates. Despite his relatively low rank, Brannew is often seen briefing the Marines on new and upcoming threats or wars, and even his higher-ranking superiors have to listen.

Perhaps because of his many years dedicated to the Marines in conjunction with his relatively old age, Brannew is well respected by many Marines, superiors and subordinates alike. Most of his battle abilities remain unknown, but for someone who survived the Summit War of Marineford, he’s not fodder to be picked off by any run-of-the-mill pirate.

6Borsalino (Kizaru)

The Oldest Active Admiral Still Flashing Across The Battlefield

As an Admiral, one of the first introduced in the series,Kizarustands out as one of the most powerful and experienced of all the Marines, even among the elite Admirals. At 58, Kizaru isn’t exactly considered young and vibrant, but he remains ever-powerful.

In his time, Kizaru has witnessed the rise and fall of powerful figures like Roger and Whitebeard. With Sakazuki’s promotion, Aokiji’s departure, and Sengoku’s retirement, Kizaru serves as the only pre-time skip Admiral still serving as an Admiral, making him one to watch out for; even more so with his Pika Pika no Mi.

5Vegapunk

The Oldest And Smartest Mind Behind Global Technology

The genius scientistDr. Vegapunk (Stella)lived a relatively long life, as evidenced by his white hair and overall aged appearance. While he would go to unimaginable lengths for his work and research in general, he still remained a very moral individual.

Aside from working for decades alongside the Marines, Vegapunkonce also worked with MADS, a group of scientists that included infamous characters like Caesar Clown, Queen the Plague, and Vinsmoke Judge. In his many years, Vegapunk achieved a lot for the Marines and the world as a whole. Unfortunately, his defiance of the World Government led to his eventual death, even as he lives on through his satellites.

4Tsuru

An Old Age Companion Of Garp And Sengoku

While most of her abilities or battle prowess remain unknown,Tsuruis known to be a renowned pirate with sufficient authority and ability. She’s a companion of both Garp and Sengoku and, with them, was one of the more prominent Marines when the pirate king, Gol D. Roger, roamed the seas.

In her past, Tsuru was fixated on capturing Doflamingo and had many run-ins with him until he became a warlord. Using both Hakiand the Woshu Woshu no Mi, Tsuru remains a powerful adversary of all pirates despite her old age.

3Bluegrass

The Perceived Older Sister Of Tsuru

As she hasn’t made her debut in theOne Pieceanime series,Vice Admiral Bluegrassisn’t yet well known, but her age allows her to stand out. As an Admiral older than even Garp and Sengoku, many wonder what she’s still doing in the service of the Marines, and joining Emperor-level battles no less.

Interestingly, Bluegrass is looked up to by Tsuru as an older sister. That says a lot about her age, considering Tsuru is from the same generation as Garp and Sengoku. Despite her age, Bluegrass is no liability to the Marines and eventakes part in the Egghead siege.

2Monkey D. Garp

The Battle-Hardened Veteran Who Still Shakes The World

Aside from being the grandfather of Monkey D. Luffy,Garp’scharisma and overwhelming strength put him above many in terms of how he is viewed overall. Despite his old age, Garp still stands asone of the strongest characters inOne Piece, as seen by the destruction he wrought on Fullalead against the Blackbeard pirates.

This makes many viewers wonder just how powerful he was in his prime. However, whatever the now-old hero of the Marines might be lacking in strength, he makes up for in experience and the legacy he’s left behind.

1Sengoku

A Marine Legend With Strategic Might

The ex-Fleet Admiral of the Marines has now retired, but during the first part of the series, he was a Marine in action. With his vast experience and powerful abilities,Sengokuled the Marines for many years, until the aftermath ofthe Summit War of Marinefordin the Marineford arc.

Even before his retirement, Sengoku was already considered an old man, but his skills made him useful. He was able to tactically lead the Marines against Whitebeard and could even go toe-to-toe with Blackbeard. As an old-timer with groundbreaking strength, Sengoku is highly respected inOne Piece.
