>>15992954Actually, Hilbert is searching the world for N even though N was in Unova this entire time and trying to find Hilbert. Seems like that whole final battle created a huge bond between the two and they want to be best friends. Apparently it was planned for Hilbert to be battleable in BW2 but it was cut in the end for GameFreak's bullshit reasons.
It's actually pretty sad if you think about, seeing how two best friends are looking for each other and will never find each other because GameFreak doesn't care.
