 These are Pokémon which have a different coloration than normal; in earlier games, this was done by means of a palette swap.Encountering a Shiny Pokémon is extremely rare; the probability under normal conditions is 1 in 8,192 (1 in 4,096 from the sixth generation onwards).There are some major exceptions to this rule, such as a red Gyarados present in "Pokémon Gold", "Silver", "Crystal", "HeartGold", and "SoulSilver", and three Pokémon present in "Pokémon Black 2" and "White 2", all of which are guaranteed to be Shiny.
