Mashikaku's facial structure resembles that of a monkey, with bushy brown hair and sideburns, tanned skin, and a square jaw. 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.
Despite being a Marine, Mashikaku was absolutely terrified of Luffy's bounty. However, it appears that he still has some courage as he fought in the war against Whitebeard.
Abilities and PowersEdit
Mashikaku appears to be somewhat strong as he survived the battle against Whitebeard and his allies.
East Blue SagaEdit
He went into the steam room when Smoker was stacking rocks and relaxing and told Smoker about the incident at the scaffolding. Smoker then gave Mashikaku orders on where each unit should be placed. He then followed Smoker and Tashigi around Loguetown for a while  and was shown to be terrified of Luffy's 30,000,000 bounty. 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.
He later accompanied Smoker to Alabasta. 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 the 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 Shichibukai in Alabasta, 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.

Anime and Manga DifferencesEdit
In the anime, he does not wear epaulettes. He was also replaced by a random Marine during Smoker's arrival at Marineford.
- His name means "Really Square", which is an accurate description of his features.
- A support character in One Piece: Grand Adventure, Navy A, bears a striking resemblence to Mashikaku. Since he is an underling of Tashigi and Navy A is a support, it is possible that they are the same person. Mashikaku wasn't named in the United States at the time of the game's release.
