Shiny Pokémon

Shiny Pokémon, often called shinies, are alternate colorations of Pokémon. Shiny Pokémon are a feature that existed starting in PMU 6, and to staff in early PMU 7. They were discontinued, and then re-added to PMU 7 on the 19th of September in 2019. Using a cosmetic item on a shiny Pokémon will in turn make the disguise Pokémon appear shiny as well.

PMU 6
In PMU 6 select wild Pokémon had a chance of being shiny. Shiny Pokémon were most commonly available to players during Holiday Cave and other events.

PMU 7
In PMU 7, shinies were first available during the anniversary Holiday Cave of 2019, with shiny spawning enabled in other dungeons over time. Pokémon hatched from Mystery Eggs cannot presently be hatched shiny. Only Generation 1 to Generation 4 Pokémon can be shiny, with few Generation 5-6 Pokémon also able to be shiny.

Shiny Pokémon while visibly different also have an asterisk (*) to the right of their name, only visible in the battle log and recruitment window. If a shiny Pokémon is on a floor or has spawned, a sound effect will play across the entire map. A player can also turn their active Pokémon shiny with use of a Sparkle Token, an item that was only available in the shop of anniversary Holiday Cave 2019.
