Under normal circumstances, there is only a one in 4096 chance you’ll find a shiny Pokémon out in the wild. Some people have played Pokémon all their lives and have never actually encountered a shiny, one of those fabled Pokémon that comes in a special, rare colour.
Remember that machine that dekuNukem built, which would find shiny Pokemon for you? Somehow, it’s gotten even better. Now it requires no human input. It will find and catch shiny Pokemon for you, in almost all situations. Hell, now it even breeds, names and clones Pokemon for you.
