Evolution
Evolution is a permanent change from one species to another, triggered by a condition such as a level, an item or a trade
Generation I used three triggers: reaching a level, using an evolution stone and trading. Gold and Silver added friendship, held items during a trade and time of day, as Eevee evolves into Espeon by day and Umbreon by night at high friendship. An Everstone held by the Pokémon stops evolution.
Main-series games; introduced in Generation I, Red and Green.
