Saw your post and just wanted to say: Zorua is a gift Pokemon in the new Black 2 and White 2 games. It is N's Zorua and as such will have N's trainer ID, and will be on level 25. No wi-fi connection needed, as it is given to you by one of Plasma's Sages after completing a certain point in the game, which will be relatively early.
If you have any more questions about the games, feel free to ask XanderO, or me, or check around the forums themselves! c:
