G-5 is a Marine branch that is located in the New World, near the Red Line. It was first mentioned by Aokiji after the Battle of Marineford and according to him, it is full of problems. It is said that the Marines of this branch are insane, cruel, and merciless who stick needles into pirates, feed them to sharks, or use them for kindling campfire. Although this is considered just rumors by some pirates, it was proven when some of the Marines lit one of the captured pirate on fire and repeatedly stabbing another pirate while hanging. They are known for not following the orders of their superiors, however, they seem to obey Smoker mostly by merit of intimidation. Some members do not wear the full formal Marine uniform and act flirtatious toward their female superior, Captain Tashigi, although they do respect her as they tried to protect her from Law and took her with them to escape from Law's sphere and reassemble her body. They do appear to not be entirely fearless, as they were hesitant to follow the Straw Hat Pirates to Punk Hazard, which the Marines had declared that no one, pirates and marines alike, should set foot on, for remnants of poisonous gas supposedly wreathed the island.
Regardless of their ruthless reputation, they seem to be easily frightened when they meet highly infamous people such as the Shichibukai Trafalgar Law. They too were helpless against the dangers of nature as seen when they panicked when a large piece of ice floated toward their ship.
