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.
Despite being a Marine, Mashikaku was absolutely terrified of Luffy's bounty.
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 was later seen in Alabasta, explaining that Nico Robin has had a bounty since she was seven. He also wanted to capture the Straw Hats after they were passed out from fighting Baroque Works, but Tashigi was against it.

- His name means "Really Square", which is an accurate description of his features.
- Mashikaku is known as "Marney the Marine" in the FUNimation dub, possibly because at least one scene features his Marine hat erroneously labeled "MARNE" instead of "MARINE". He is also J. Michael Tatum's favorite One Piece role.
- 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.
