>>18219390N is actually a physical manifestation of a young boy's nightmare.
All kids like to do is have fun, however way they do it, they still just want to have fun. Some boys on the other hand have nightmares of having a life where they can't have fun.
A life with no family
A life by yourself
A life...alone
However, N purged that feeling of being alone by creating imaginary friends he call: Pokemon. There's a reason why he is the only one who can actually talk to Pokemon, because they were created through his mind, he is the only one who can see them, he's living a hell, and making unreal beings of magic were the only ways of coping with it.
This is why people think he's crazy, why Ghetsis tried to take advantage of him, why he actually thought he could split the world into a black one and a white one.
N is the little boy who thought he could, but in reality can't. Faggot.
