Very, very. very interesting news. I thought N's real name was Nicolai based off a thread here that was previously discussed (backed with a good name theory as well). Now, Natural Harmonia Gropius is one of the most interesting names I have ever heard, and it really seems to give meaning on N's name. The name Natural really seems to stick on me. After all, N (or who I should really call now "Natural") is one of my favorite Pokemon characters of all time.
With this in mind, I hope that Gamefreak will input his full name into the third version of Black and White. By adding giving his full name, I'm sure it'll add more to the story (perhaps Ghetsis was a mean father and simply just called him N).
