Dokukurage said:Maybe in White (nature themed) he'll think Pokemon are too powerful and the opposite in Black (since it's technologically themed); that humans hold too much power in the world. Maybe he'll just want to balance it out.
Also, that's probably where the legendaries come in. As Black version will be more industrialised, N will probably use Reshiram (the nature Pokemon) to balance out industry and nature, and vice-versa for White version.
Edit: I guess I repeated what you already said lol
