Since 1996 and the release of Pokémon Red and Blue, fans fo the Pokémon series have been able to explore a new region of the Pokémon world with each new iteration, with inspirations ranging from different Japanese islands to the bustling city of New York. As the anime follows the video games fairly closely, it would be safe to assume that the regions shown in the RPG series are all the world has to offer.

That is, in fact, not the case, and there are more regions of the Pokémon world seen through spin-off titles such as Colosseum and Mystery Dungeon that never appear in the mainline Pokémon RPGs.

9 Orre

Pokemon Orre region from Colosseum and Gale of Darkness

Orre, based on Phoenix, Arizona, is the region players explore in Pokémon Colosseum and later return to in Gale of Darkness, both on the Nintendo Gamecube. Unusually for a Pokémon region, Orre has no wild Pokémon to speak of, though that begins to change in Gale of Darkness with the appearance of Poké Spots. As many Pokémon in Orre are used for criminal acts, the player's main goal in Orre is to catch Shadow Pokémon, partners who have had their hearts artificially shut in a plot point that seems more suitable in Kingdom Hearts than Pokémon.

8 Fiore

Fiore from Pokemon Rangers

The setting of the first Pokémon Ranger game, Fiore is unlike many other regions in Pokémon, as there are no trainers to speak of, no Pokémon League, and, by extension, no Pokéballs at all. The ones who interact with Pokémon the most are the titular Pokémon Rangers, who use wild Pokémon to help keep the peace with both humans and Pokémon while ensuring their freedom by not capturing them. The less extreme sect of Team Plasma would fit right in with the Pokémon Rangers.

7 Almia

Almia from Pokemon Rangers 2

The location of the second Pokémon Ranger game, Shadows of Almia, it has many similarities to Fiore, in that there are no Pokémon trainers to speak of. Almia is also the home to the evil and unfortunately named Team Dim Sun, which is far too close to sounding like a gang of chefs than Pokémon thieves.

Like many spin-off regions, it is unclear where exactly Almia fits on the map, but fan theories indicate it being close to Sinnoh, as it is stated it is the closest region to Almia for transporting Pokémon eggs, as well as its desert region looking similar to Orre from Pokémon Colosseum.

6 Oblivia

Oblivia from Pokemon Rangers 3

The third and final game in the Pokémon Ranger series, Guardian Signs, takes place in Oblivia, an archipelago of several islands not unlike Alola. Like Fiore and Almia, Oblivia has no Pokémon trainers and has Rangers in its place, with them being largely responsible for peacekeeping duties. Although there is no real word on where Oblivia is in relation to the mainline Pokémon world, it is said to be south of Almia and Fiore, giving it at least some geographical reference in its own series.

5 Pokémon World

Simply named the Pokémon World, this is the mysterious place where the Mystery Dungeon series takes place. It is populated by only Pokémon and is somewhat reminiscent of Digimon World in its approach to characters and infrastructure. Although it is entirely separate from the rest of the Pokémon series, it is established that it is possible for humans to travel there, though there is no explanation as to how or why they would do so.

4 Pokémon Island

The setting of Pokémon Snap, this island is a haven for many kinds of Pokémon, which makes it the perfect place for a budding photographer like Todd Snap. Since there are no humans living on Pokémon Island, the inhabitants appear to be less frightened of humans than they are in the rest of the world, giving both Professor Oak and Todd a good look at how Pokémon act in their natural habitats.

3 Ferrum

Ferrum is the setting of Pokkén Tournament, and is much different from any other region in how it deals with Pokémon battles. Instead of trainers sending out Pokémon and giving battle commands, they use the power of Synergy Stones to battle as one with their partner Pokémon.

While Ferrum isn't as fleshed out as other regions, since the central aspect of the game is the battles, there's enough background information to make it a region worth visiting.

2 Ransei

Ransei from Pokemon Conquest

The Arceus shaped island of Ransei that players can explore in Pokémon Conquest is yet another region with a unique take on the Pokémon formula. Taking a much more feudal approach to the Japanese setting, Ransei's 17 regions each have their own castle structure and are home to one of the then 17 Pokémon types, and is unique for the humans of the region being able to transform in a way similar to Pokémon evolution.

1 Pasio

One of the most recent additions to the Pokémon world comes in the island of Pasio, the setting of the Pokémon Masters mobile game. Unlike many other regions, the main attraction of Pasio is three on three trainer battles, with each trainer using up to two Pokémon each. Like Orre, there are no wild Pokémon on Pasio as it is an artificial island created for the sole purpose of battles, and the only Pokémon seen are the partners of trainers who travel there to take part in the tournament.
