Pokémon Opalo is a highly regarded Spanish-language fangame created with RPG Maker XP and Pokémon Essentials. Its Pokédex is not a simple copy of any main series game; instead, it is a custom regional Pokédex featuring a curated mix of Pokémon from Generations 1–7 (and some from Gen 8), along with regional forms, altered evolutions, and a handful of original Fakemon designed to fit the Opalo region’s lore. The total Pokédex size is 386 Pokémon (a deliberate callback to Gen 3’s Hoenn Pokédex).
Pokemon Opalo introduces 24 new regional forms that fundamentally change the typing and roles of classic Pokémon. Notable entries include: Pokemon Opalo Pokedex
Every journey begins with a choice, and the Pokémon Opalo Pokédex offers a starter trio that rivals the official generations in design and concept. Report: The Pokémon Opalo Pokédex 1
