i know I have to complete the pokedex in order to get to the sanctuary. but do I have to see ALL the Pokemon. or just the ones in black2 or white2.
You have to see all the Pokemon in the unova pokedex.Exceptions are Victini,keldeo,meloetta and genesect since they event legendaries and it is not required to add them to your pokedex to visit the nature preserve.
