Pokémon Ranger: Shadows of Almia was released in 2008 for the Nintendo DS.
This game contains 267 of the first 493 Pokémon, with an additional three Pokémon being available with access to event missions (for a total of 270 available Pokémon).
In 2016, Shadows of Almia was rereleased for the Wii U Virtual Console. Unlike the original releases, this version is not capable of communicating with any other Pokémon game.
Unless stated otherwise, all pages listed here are works in progress as I play through the game to verify data.
