Question: pokemon ultra sun and moon how to get national pokedex?
Answer: Unfortunately you can't get the National Pokédex in Ultra Sun/Moon. You can use Pokémon Bank to check the National Pokédex status though. This is the same for all Gen VII games, meaning the Shiny Charm only needs you to complete the Alola Dec, which is a plus. There is no National Dex for the Alola games.
