Trivia

 * There is a continuation of an easter egg that refers to the names of the Eevee Brothers, despite the fact that Sakura wasn't member of Eevee Brother, naming Eevee with her name will result in a Espeon when it is evolved.
 * Works only once per account and even if Eevee was already evolved into Espeon not using this method.
 * Walking an Eevee Buddy 10 km or more, and evolving it will cause it to become an Espeon during the day.
 * Along with Umbreon and Feebas, Espeon is the only Pokémon in the game that to evolve into it, there's no evolution item required but the evolution is the only way to acquire this Pokémon.
