You have see to many different pokemons. Then you will fill it (you have to every Pokemon to get national pokedex).

In the Sinnoh Pokedex, there are 493, from (#1) Turtwig to (#493) Arceus.

See every Pokemon in the Sinnoh Dex and beat the Elite 4 The Elite 4 provides many Pokemon to see for the Sinnoh Dex that no one else has. Good tip (Dont skip trainer battles. Although they are annoying, they carry most of the Sinnoh Dex Pokemon)

210 from Turtwig to Giratina

493
