Meloetta...isn't she one of those pokemon from the Black/White versions that can only be obtained via an event (or by trade in Black/White 2)? Guess it makes sense I've never heard of this one until now.

I like the design of the "Melody Pokemon" (from what the in-game pokedex describes) as well...she has something of a pop idol/singer look about her, given the wavy green hair, dress, and headset mic-like appendage on her head. :)

From what I've looked up online, this is her "Aria" (Normal/Psychic-type) form, and once a certain specific move is taught to it, it can change to a "Pirouette" (Normal/Fighting-type) form as well.

I wouldn't know that much since I haven't finished playing Black/white. But I've seen tons of fanart of her.

Ah, I see.
