Evolution

Methods are the current official ones. A ROM hack may change them — trade evolutions especially; the guide table below says which do.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
