Gamefreak was really stupid when it came to naming N. Where are the characters with names consisting of the various letters before N.
His full name is N Harmonia Gropius, I've heard.
N Harmonia sounds like "enharmonia," which is a musical term, that, IIRC, means two different notes that sound the same (C-sharp and D-flat, for example), representing N's feelings about treating Pokémon right versus the player's. Same goal, different method.
Also, lul. "N" is stupid. Says Mr. Love-type.
Anatidaephobia is the fear that somewhere, somehow, a duck is watching you, staring into your soul, using its duckiness. QUACK.
N's name is highly symbolic. N is short for Natural, confirmed by Bulbapedia, which refers both to natural numbers (integers, without zero and the negatives, both emphasizing his uniformity and the recurring math motifs) and to how ironically unnatural his life was. N is also a variable, and he's one of the few characters with genuine character development. N Harmonia sounds like enharmonic, a musical term meaning having the same sound (C sharp and D flat, for example), representing how truth and ideals really are almost the same concept. Gropius I have NO idea about; Bulbapedia says it might have something to do with an architect. Also, the one-letter name (along with the real name) was given to him by Ghetsis (whose last name is Harmonia), which fits with Ghetsis' general dehumanization of N. So his name (except for Gropius and whatever that means) is a perfect representation of his character.
