Heres ny theory...Looker in B/W was actually Ghestis in disguise. He made your character do all the work to find the other sages and now hes rebuilding the team. This theory makes sense, right?
No, that doesn't make any sense at all. Ghetsis was taken care of.
-N as the player. Massively far-fetched, but it would be awesome imo. Have N lose his Dragon at the start (to Ghetsis and Kyurem?), and have him receive a starter from Bianca and challenge Gyms because why not. It would be similar to Black and White, but still be a sequel.
Wont happen. The main series games are always a nameless, speechless hero that the player can project themselves onto. By becoming an actual character you break that.
