Jirachi is a dual-type Steel/Psychic Mythical Pokemon introduced in Generation III.

Jirachi hibernates for extensive periods, forming a protective crystalline shell as it sleeps. However, it is still capable of fighting while asleep if it is in danger. It awakens for seven days every thousand years, but can also waken if sung to by a voice of purity. During the short periods when it is awake, Jirachi is said to grant wishes.

trivia

• Despite being legitimately obtainable in Generation III, Shiny Jirachi were previously locked out of Generation VI's Wi-Fi features prior to an update, and were also blocked from entering Pokémon Bank until after the 2014 Tanabata Shiny Jirachi event was released in Generation VI; this makes Jirachi the only Pokémon to have undergone this kind of issue.
