Shiny Pokémon

Shiny Pokémon is a specific Pokémon with different coloration to what is usual for its species. It is one of the many differences that a Pokémon can have within its species.

When a Shiny Pokémon appears in the wild or from its Poké Ball, it is surrounded by a flash of stars or light, which is accompanied by a pinging sound effect.

Shinies encountered will also have the word 'Shiny' in front of their name.

Coloration
Form differences, such as that of Shellos and Gastrodon, are not normal/Shiny variations of one another, but the individual forms can be Shiny.

Shiny Pokémon can differ in color from their normal counterparts very little or very much. Some Pokémon, such as Gengar or Pichu, have a Shiny coloration only a few shades darker or lighter in color. Conversely, some Pokémon, such as Caterpie or Gyarados, have dramatic differences in color.

An evolutionary line is not necessarily guaranteed to have similar Shiny colorations even if their standard colorations are the same; both Ponyta and Rapidash have orange flames, but a Shiny Ponyta has blue flames while a Shiny Rapidash has gray flames. Sometimes, two Pokémon in an evolutionary line with different standard colorations will have the same Shiny coloration, as in the case of Skitty and Delcatty.

Basic Rules
Individual Pokémon cannot change their Shininess. A Shiny Pokémon will always be Shiny, and a regular Pokémon will never become Shiny. Upon evolution, a Pokémon retains its Shiny status; for example, a Shiny Charmander, if leveled up, will eventually become a Shiny Charmeleon and then a Shiny Charizard, while a regular Charmander will become a regular Charmeleon and then a regular Charizard.

Players, trying to use moves that would faint the Shiny Pokémon or flee from them, will get a prompt to confirm their actions.

Secret Shiny
A Secret Shiny is a rare shiny particle variant. Secret Shinies appear the same as normal shinies but with a different particle effect. This particle effect replaces the normal shiny particle; players can't have a Pokémon with both the Secret and normal Shiny particle.

Secret Shinies only appear in single encounters or naturally-occurring hordes (not in hordes summoned by Sweet Scent and not via breeding). When you encounter a Shiny Pokémon, there is a 1/16 chance that it is a Secret Shiny instead of a normal shiny.

Players can breed Secret Shinies with 'normal' Shinies and the Secret Shiny particle will be passed on to the Egg. Remember though that you cannot have both the normal and Secret Shiny particle on the same Pokémon.

Shiny Rates
The players have 1/30,000 chance to find a Shiny Pokémon in a single encounter. This means that horde encounters have a dramatically increased probabily to encounter a Shiny Pokémon.

This can be further increased if the player has an active Donator Status or Shiny Charm.
