Pokémon Gold and Silver Versions/New Features/Shiny Pokémon

These games introduced Shiny Pokémon—Pokémon which have a different coloring than their species has normally, and which appear very rarely (a 1 in 8192 chance). In these games, Shiny Pokémon often have higher stats than regular Pokémon, but can never achieve maximum stats for that species (as Shininess is based on the Pokémon's s in this generation).

In this generation, the odds of an hatching into a Shiny Pokémon can be significantly increased if one or both parents are Shiny.

There is one Pokémon guaranteed to be Shiny: a Red Gyarados can be found at the Lake of Rage. Since it is part of the storyline, it is impossible not to encounter this Pokémon as Shiny.
