Klefki is a small, grayish-white Pokémon resembling a key ring with four keys on it. It has a spherical head with a white face and a small, pink oval on its forehead. Two black circles and a keyhole form its eyes and mouth. Below its head is its pink, teardrop-shaped body with a white marking in the middle. Extending from the top of its head is an appendage, which resembles an old-fashioned key with two wide, blunt teeth. A thin loop surrounds Klefki, and connects at either side of the "key". Hanging from the loop are various keys that this Pokémon has collected. If Klefki finds a key it likes, it will never release it. To threaten attackers, this Pokémon jingles its key collection. Klefki is the only Pokémon capable of learning Fairy Lock.
A wild Klefki debuted in Gathering Klefki, which Grace had befriended. It helped her break free from her cells numerous times, and later helped free the Vaniville Town residents by stealing the keys of a sleeping Team Flare Grunt and using them to open their cells.
This Klefki later acquainted itself with X and his friends, giving X Clemont's glasses and allowing him to deduce the location of Team Flare's base. He eventually set off without informing the others.
