Shiny Pokémon are Pokémon that have an unnatural coloration. A Pokémon has a very rare (1/8192) chance of being shiny, and they are much sought after for their unique look. The coloration can be mild - only a few shades darker or lighter than the original - or drastic. A shiny Pokémon will emit particles and have a star under its level while in battle with a trainer. Wild shiny Pokémon will not engage in battle with other wild Pokémon,
It is possible to spawn a shiny Pokémon by typing the command "/pokespawn name of Pokémon s". For example, "/pokespawn mareep s".
Pictures of the shiny forms of each Pokémon can be found here.
