In the "Pokémon" games, a shiny Scyther is a Scyther with a dark green body with red coloring between its body segments. A non-shiny Scyther has a light green body with cream coloring between its body segments.
Shiny Pokémon were introduced in the Generation II games of the "Pokémon" series as Pokémon with an alternate coloration to the standard color palette. In Generation II, shininess is determined by a Pokémon's Individual Values, while in future generations it is determined by the original trainer's ID, a secret ID and the Pokémon's personality value. From Generations II to V, the base probability of finding a wild shiny Pokémon is 1 in 8,192. This probability is doubled in Generation VI to 1 in 4,096.
