Evolution/Side games/GO

In Pokémon GO, the player can evolve Pokémon by spending Candy. The Candy cost for evolution varies between Pokémon species, ranging from 12 (to evolve into ) to 400 (to evolve  into  or  into ).

Each evolutionary family has their own kind of Candy. Candy can be obtained by catching or hatching Pokémon of that evolutionary family, or by walking with a Pokémon of that evolutionary family as a Buddy Pokémon. The player can also obtain 1 Candy for its evolutionary family by permanently transferring it to Professor Willow.

In Pokémon GO, species that require a held item (except ) or a Sun, Shiny or Dusk Stone to evolve in the core series also require an item to be spent in addition to Candy. For evolutions introduced in Generation II, the item required is the same as in the core series; for evolutions introduced in Generation IV, a Sinnoh Stone is required instead.

Normally, evolves into, , or  at random. If Eevee is the current Buddy Pokémon, and has walked at least 10 km with the player and obtained at least two Candies, it will evolve into in day mode or  in night mode. However, if Eevee is nicknamed after one of the Eevee brothers (for Vaporeon, Jolteon, or Flareon) or the Kimono Girls in the anime (for Espeon and Umbreon), it will be guaranteed to evolve into the corresponding evolution, although this can only be performed once for each nickname.
