Police on Earth
The police on Earth in the Dragon Ball franchise are all very similar to their real life counterparts. Their main purpose seems to be protecting single city's and towns that do not require the work of the two military groups. Their weaponry and such is also more limited, such as only the use of smaller guns and occasionally Rocket Launchers etc. As far as their transportation goes, they use scooters, motorcycles and different kinds of police cars and hovercars. A notable member of the Motorcycle Police Squad is a policewoman modeled after and voiced by the Olympic gold-medalist Kaori Matsumoto in the movie Dragon Ball Z: Battle of Gods; the policewoman observes the battle against the God of Destruction Beerus from afar and wonders if Capsule Corporation is using fireworks again when she sees an explosion cause by one of Vegeta's attacks on the God of Destruction.
They seem to have ranks that are all from the real world, such as sheriffs and chiefs. The police sometimes use wanted posters. The uniforms are near perfect replicas of the real life police, with the use of hats, helmets and blue uniforms, as well as the use of handcuffs to arrest the opposition and occasionally a microphone to give speeches.
The police in the Dragon Ball franchise are rarely if ever shown using animals in their squads. In fact, some are anthropomorphic animals themselves. The police are seen many times in the series attempting to arrest and sometimes even kill the villains. However, they always failing and usually getting killed or injured in the effort.
Police also exist on other planets, such as Imecka, and a Cosmic Police Organization even exists in the universe. However, they do not have enough power to oppose Frieza's Planet Trade Organization and the Saiyans. In Dragon Ball: Episode of Bardock, upon his arrival on Planet Plant, Chilled decides to disguise himself and his soldiers as members of the Space Police in order to trick the indigenous population into revealing what happened to his two men, Toobi and Cabira, and bring whoever defeated them to him. Turles' second in command Amond was originally an atrocious criminal who rampaged throughout the entire galaxy before being arrested by the Galactic Police and imprisoned on planet Nutts. A Galactic Patrolman named Jaco is the main protagonist in the manga Jaco the Galactic Patrolman: he came to Earth in order to stop a dangerous invader, Goku. Jaco says that the Galaxy Patrol only has 38 members and they operate under the direct orders of the Galactic King, who is shown to be a Martian in a flashback that also shows a Namekian and a Tech-Tech alien in their ranks. It is very hard to become one, as currently, there is only a 5/9 (55%) chance to become one. Jaco also says he is the third tallest member of the Galactic Patrol, and he is 4'10".
