From Bulbapedia, the community-driven Pokémon encyclopedia.
This is a list of Pokémon in the order dictated by the Capture Styler's Browser in the Oblivia region. Oblivia features a different list to the Fiore Browser and Almia Browser as many of the species found there are native to one or neither of the previous Ranger-patrolled regions.
Pokémon Ranger: Guardian Signs uses the same methods of categorization as its predecessor. However, some adjustments have been made to many of the returning Pokémon and there are no longer any Field Moves unique to a single species, with the one exception of Staraptor's Fly.
Note, however, that this list only applies to the main game. The Browser contains a separate list in the past, changing the ordering and omitting 81 of the Pokémon from the main list in the process.
