Klefki is a Generation VI Steel/Fairy type Pokémon introduced in Pokémon X and Y. It is known as the Key Ring Pokémon. Klefki has the unique ability to collect and utilize keys, making it an intriguing Pokémon in terms of its nature and abilities. Klefki is small in size, standing at just 0.2m tall and weighs about 3.0kg. Its body is predominantly silver and resembles an old-fashioned key, with a head that's shaped like a key's bit. Klefki has a circular, key-ring-like appendage on top of its head in which it collects keys. Klefki has the unique habit of stealing keys, and it is said to never release a key that it likes. So, it uses its body to hold onto numerous keys, which jingle around when it moves. In terms of abilities, Klefki can have either the "Prankster" ability, which increases the priority of status moves, or the "Magician" ability, which allows it to steal an opponent's held item after using a move. Klefki doesn't evolve from or into any other Pokémon, making it a standalone species within the expansive Pokémon universe. It's noteworthy for its unique design, its intriguing habit of collecting keys, and its competitive abilities in battles.
