Trivia

 * Since Generation VI of the core game series, Eevee can evolve into Sylveon, but this is not currently possible in Pokémon GO.
 * Since 0.163.0 update, Eevee has a gender difference. Tail of female has heart-shaped pattern.
 * This was implemented more than one year later than the launch of Pokémon Let's Go.
 * As an update of Pokémon GO was released on April, 2021, it was revealed that the naming trick for evolving Eevee into Sylveon is "Kira". However, evolving a Eevee with the name "Kira" resulted in a "Network Error" at that moment.
