Meloetta seems to be a femininely anthropomorphic figure with musical bar-style streaks in its hair, quarter notes (♩) for its arms and hands, and pupil-less eyes resembling whole notes. It has a third eye or a jewel on its forehead and a black headpiece that seems to be shaped like a rabbit. Its ovular head seems to be 1/3 its body's height and about half its height in width. In its Aria Forme, it has flowing, wavy green hair and light blue eyes. In its Pirouette Forme, it has auburn hair that seems to be stylized in a high bun and red eyes. In either Forme, its midriff and eyes match its hair.
Gender differences
Meloetta is a genderless species. Often referred to as a female.
Special abilities
According to artists in Unova, Meloetta's beautiful music and dance inspired many works of art, music, and songs. This made the Pokémon popular among both musicians and dancers.
Meloetta is able to change forms when it uses the move Relic Song, which changes its form from Aria Forme to its Pirouette Forme, or vice versa. In its Aria Forme, it is a dual-type Normal/Psychic-type Pokémon; in its Pirouette Forme, it is a dual-type Normal/Fighting-type Pokémon. It reverts to Aria Forme when switched out or the battle ends.
Behavior
In its Aria Forme, Meloetta can sing beautiful songs. While in its Pirouette Forme, Meloetta can perform graceful dances.
Meloetta once played a song and danced so lightly, it filled people's hearts with joy. However, when sorrow darkened the world, Meloetta lost the melody. At the same time, its red shoes were lost somewhere.
Upon entering the cafe in Castelia City, a guitarist, who knows of the story, remembers Meloetta's melody. Upon playing it, Meloetta remembers the song that it had danced to.
Meloetta is the only Generation V Pokémon able to learn Perish Song.
The red shoes mentioned in the history may be a reference to the Hans Christian Andersen fairytale The Red Shoes.
Meloetta was leaked on a poster for M15 during the release of Black and White 2.
Origin
Meloetta's Aria Forme also resembles a typical singer with the black headpiece acting like a head microphone, while the Pirouette Forme resembles a ballerina wearing a tutu and its "hair" curled up in a bun. Its headpiece resembles a G clef.
Name origin
Its name likely derives from "melody," and a corruption of the word "pirouette", a type of movement in ballet. "-Etta" is also a common, feminine Italian suffix meaning "little," and could be a reference to Meloetta's feminine look and diminutive size. Italian words are commonly used for musical directions and descriptions. Meloetta's name may literally mean "Little Melody."
Aria is a term now used almost exclusively to describe a self-contained piece for one voice usually with orchestral accompaniment, and is commonly used in opera.
Pirouette, literally "to whirl", is a controlled turn on one leg, starting with one or both legs in plié and rising onto demi-pointe (usually for men) or pointe (usually for women). The non-supporting leg can be held in retiré position, or in attitude, arabesque level or second position.
