From Bulbapedia, the community-driven Pokémon encyclopedia.
The Decolore Islands (Japanese: デコロラ諸島 Decolora Archipelago) is an anime-exclusive region consisting of a large chain of islands. It is located between Unova and Kanto.
It is inhabited by Pokémon that can be found in Kanto, Johto, Hoenn, Sinnoh, and Unova. The archipelago is sparsely populated, having only some coastal towns and many nature preserves. The region first appeared in Farewell, Unova! Setting Sail For New Adventures! when Ash, Iris, and Cilan decide to visit the Decolore Islands in order to travel together from Nuvema Town to Vermilion City.
- This is the second archipelago region that Ash has visited, the first being the Orange Archipelago. However, unlike the Orange Archipelago, there is neither any type of League known to exist in the Decolore Islands nor any regional Professor.
- This is also the only region in which neither Ash nor any other main character has caught a new Pokémon.
- This is also the only archipelago to not include a villainous team.
- Decolora was used as the OT of Japanese Jirachi event distribution via Wi-Fi in 2013, a reference to Jirachi's appearance in Searching for a Wish!.
