For the anime non-canon pirate of Foxy’s crew, see Mashikaku (Non-Canon).

Chief Petty Officer Mashikaku is a subordinate of Smoker and Tashigi. However, it is unknown if he remained with the two after they transferred to G-5 as he is not seen with the G-5 Marines.


Mashikaku’s facial structure resembles that of a monkey, with bushy brown hair and sideburns, tanned skin, and a square jaw. His signature features are his sideburns that are curved and pointed inwards towards his face and his mouth that is pointed upwards when closed. He wears the standard Marine shirt and cap. In the manga, he wears epaulettes which may serve to differentiate himself in rank as a Chief Petty Officer. In the anime, however, he lacks the epaulettes and so, in terms of uniform, looks no different from a common Marine sailor.

During the Summit War of Marineford, he wore a Marine officer’s coat over his standard Marine shirt.


Mashikaku is somewhat afraid of those with a higher authority than him, as shown when he was afraid of what the higher-ups would say if Smoker disobeyed them, and was also afraid of Smoker when he shouted at him that he did not care.

Abilities and Powers

Mashikaku appears to be somewhat strong as he survived the battle against Whitebeard and his allies.


While in Arabasta, Mashikaku carried around a long rifle.

During the Summit War of Marineford, Mashikaku was seen armed with a large sword behind his back.


East Blue Saga

Loguetown Arc

While Smoker was stacking rocks and relaxing, Mashikaku barged into the steam room and told Smoker about an emergency involving pirates at the town square. Smoker then gave Mashikaku orders on where each unit should be placed. He then followed Smoker through town and when they encountered Tashigi, Mashikaku handed her her jacket. Later, when Smoker decided to head out into the Grand Line to chase after Luffy, he expressed concern over how the higher-ups would react if Smoker were to abandon his post, but Smoker simply told him to report to them that they do not get to order him around.

Arabasta Saga

Arabasta Arc

Mashikaku later accompanied Smoker to the Arabasta Kingdom. In Nanohana, Smoker wondered what the commotion occurring in the restaurant in front of them was. Mashikaku then came running towards Smoker and Tashigi from that direction and told them that they would never have guessed who showed up in town. Later, after Smoker encountered Luffy in the restaurant, Mashikaku was seen wiping down his sweat as his captain yelled at Tashigi to chase down the pirate.

After Ace helped Luffy escape, Smoker wondered how they would locate the Straw Hats in such a large country. Afterwards, Tashigi and Mashikaku came running back to Smoker, who then asked them where they were. Mashikaku told him that they were at the opposite side of town, to which Tashigi then tells him to shush. When Smoker started to discuss how he was having a bad feeling about a certain Warlord in Arabasta, Mashikaku asked him if he was talking about Crocodile.

Later, in Alubarna, the Marines encountered Miss All-Sunday holding Nefertari Cobra hostage. Upon seeing her use her Treinta Fleur, Mashikaku immediately stated that he recognized the woman to be Nico Robin. He then warned his men that she had had a bounty since she was eight. Tashigi then ordered him to take the Marines to the city square to stop the bombing while she dealt with Nico Robin.

After Crocodile was defeated at the hands of Luffy, Mashikaku wanted to capture the Straw Hats after they had all passed out from exhaustion fighting Baroque Works. However, Tashigi forbade him from arresting them.

Summit War Saga

Amazon Lily Arc

Upon the summons to reinforce the headquarters ahead of the execution of Portgas D. Ace, Mashikaku walked behind Smoker and Tashigi as they arrived at Marineford

Marineford Arc

Before the war began, Mashikaku, Smoker, and Tashigi listened on as Sengoku revealed Portgas D. Ace’s past to the Marines.

Towards the end of the war, Mashikaku stood alongside Smoker, Tashigi, and Hina after Shanks arrived at Marineford and Sengoku declared the war to be over.

Translation and Dub Issues

His name is a katakana rendering of Mashikaku (真四角?), an old-fashioned term for squares that is – fittingly enough – commonly used to describe strongly angular faces.

Being a databook-exclusive fact, his name didn’t appear in any licensed English translation of the series until World Top 100. Taking advantage of this, some English-speaking fans jokingly named him “Marney the Marine” (stemming from an animation error in Episode 52 that misspelled his cap label as “MARNE”), something even his Funimation voice actor J. Michael Tatum eventually acknowledged.

Anime and Manga Differences

Whereas Mashikaku made his manga debut after the Buggy and Alvida Alliance were causing trouble in the town square, his anime debut was, instead, when he received the new bounty of Monkey D. Luffy and ran to report to Smoker of it. Furthermore, he was not shown with epaulettes in his anime debut.

He was also replaced by a random Marine during Smoker’s arrival at Marineford.


  • His appearance in Chapter 550 can only be seen in older versions of the chapter.
  • The 4Kids-licensed video game One Piece: Grand Adventure assigns Tashigi a support character, “Navy A”, that appears to be modeled off Mashikaku.
    • In addition, Tashigi’s in-game profile states she is the leader of the “Mashikaku (Perfectly Square) Troop”.
