The Ranger Union (Japanese: レンジャーユニオンRanger Union) is an organization in the Pokémon Ranger series that aims to protect humans and Pokémon. Members of the organization are known as Pokémon Rangers, who use Capture Stylers to maintain peace in the region where they work. The Ranger Union is known to operate in Fiore, Almia, and Oblivia.
The Ranger Union headquarters play a major part in the story of Shadows of Almia. The player visits once with Barlow while stationed at the VientownRanger Base. He/she is promoted to the rank of Top Ranger after the events at the Cargo Ship, and moves to the Ranger Union headquarters to continue his/her Ranger duties there. Late in the game, after clearing the Oil Field Hideout, the building is attacked by Team Dim Sun, and the player must defend the institution.
Although the Ranger School stresses the importance of Rangers, Operators, and Mechanics working together, there are no Mechanics at the Ranger Union headquarters.
The Ranger Union has an azure globe with meridians as insignia, as seen in the Glossary from the first game of the series. The globe represents worldliness, and might thus hint the Union is an organization operating world-wide. Below the globe, however, an arrow-like shape is seen. It might be a reference to the motion of the Styler's top-like part resembling that of a planetary orbit.
Inside Rand's House in Pokémon Ranger: Guardian Signs, players can see on the wall what is assumed to be Ranger Union's flag : a red field with a gray-bordered white oval in the centre containing the Union's globe. The same colours are seen on professional Stylers as well as the uniforms worn by most Rangers.
