Clefairy is a small, pink Pokémon with a cute appearance. Many people think Clefairy looks like a combination of two Pokémon, because it has a body like a Jigglypuff's, but ears like Pikachu's. Its ears are brown and it has a long tail.
Clefairy can have the ability Magic Guard or Cute Charm. Cute Charm allows Clefairy to have a 30% chance to infatuate the foe if the foe is the opposite gender and a physical attack hits Clefairy. Magic Guard allows Clefairy to only get damage by attacks. Clefairy can jump very high, as seen in the anime, and can hear very well. This is often the reason why they are hard to find.
Clefairy is very timid and rarely appears in front of humans. But it is very clever, and there are awareness among social and religious groups.
Despite having wings, Clefairy can't learn any moves involving its wings nor is it Flying-type too.
Clefairy was going to be called Aria.
Clefairy is the only non-Psychic-type to learn Cosmic Power along with its evolutionary family.
Originally, the Pokémon that Prof. Oak was going to give Ash was a Clefairy. This means that Clefairy was going to be the face of the Pokémon Franchise. This idea was later scrapped at the last minute for Pikachu, because Pikachu was more popular than Clefairy.
Clefairy is one of three Pokémon that can learn the attack Meteor Mash, and the only non-Steel-type to learn it.
Clefairy appears to be based on a star-shaped fairy whilst its name probably comes from clef (as in music) and fairy.
