Ancient cultures offered keys to Klefceus, believing it would bless family bloodlines with luck. Witnesses describe it galloping across the sky while producing constant jingling sounds.

It is described in mythology as the Pokémon that shaped the universe with its 1,000 arms. It never lets go of a key that it likes, so people give it the keys to vaults and safes as a way to prevent crime.
