As we can see, while Pikachu dominates on a global scale — accounting for roughly one in every 10 Pokémon-related searches around the world — local favorites crop up from country to country. Several clusters appear in various regions. In Europe, the tortoise-like Golem is the most uniquely popular Pokémon in the adjoining countries of Germany, Switzerland, Austria, and Slovakia.
Onix is the most popular Pokémon in the cluster of Argentina, Uruguay, Brazil, and Colombia, with searches for the boulderous serpentine occurring as much as eight times the global average rate. The rare, versatile Eevee is the most uniquely popular Pokémon in four countries — Denmark, Finland, Latvia, and Lithuania, with searches for these Pokémon occurring at twice the rate it does globally.
