It seems that there is MUCH more to N than we thought after his background being revealed. If he was born from Pokemon, could he be one? Zorua and Zoroark in the event both transformed into humans. Also, N owns a Zoroark. Could his Zoroark have more of a relation to him than just being one of his Pokemon? In the intro of both Black and White, N is shown as a kid with a Zorua, so he's had it for awhile. Zoroark and Zorua are known to be tricky, so that could be why N is so smart. That's just a theory, though.
He could be Kyurem. He seemed to want you to catch the main legendary dragon of your game as he said he'd give you a chance when he got his dragon. The goal of team Plasma is to release Pokemon from their trainers, so why would he encourage you to catch a legendary Pokemon? My theory is he wants to seperate Reshiram and Zekrom. He wants two opposite trainers who have almost nothing in common and would rarely cross paths (the player and N) to have Zekrom and Reshiram. This may be so that Zekrom & Reshiram never see each other, so they could never fight. When his plan fails (his plan would be so elaborate because he's very smart) and the dragons are released (somehow both would be released in Gray, mayebe the player released theirs) he must fight them as Kyurem, in order to stop their fued (like in Ruby and Sapphire). In BW, you don't see N after the main story (I don't think) and you can't battle Kyurem until after the main story as well. Again, just a theory.
