Jirachi

Jirachi is an Steel/Psychic-type Legendary Pokémon that first appeared in Pokémon Ruby and Sapphire. It sleeps for a thousand years before waking for seven days, and has the ability to grant wishes while awake. In Super Smash Bros. Brawl, it can be spawned from a Poké Ball and is one of the few Pokémon that does not fight; Jirachi instead flies away while dropping stickers. It has a 1/493 chance of being summoned, which is a reference to the number of Pokémon that existed at the time of Brawl's release.
