Shiny Pokémon



Shiny Pokémon are extremely rare Pokémon that differ in coloration from their regular appearance. These color variations may range from minor hue adjustments to completely new palettes. Only one shiny coloration exists for each Pokémon species.

In the Map View and tracker, shiny Pokémon are shown in their regular coloration until they appear on the encounter screen or on the summary page, where they have an aura of stars around them and their different coloration is visible.

Once a player captures a shiny Pokémon, their Pokédex will show that they have captured it and additional switch buttons for shiny forms will unlock in each individual Pokédex entry.
