In Pokemon Platinum to get the National Dex you will need to have seen all 210 Pokemon in the Sinnoh Dex then talk to Professor Rowan and then after a while Professor Oak will give you the National Dex!
The sinnoh dex has 210 pokemon, and the national dex has 493 pokemon. It has an entire 664 pokemon (I think)
no to get the national dex you must defeat the elite four, and have at least 60 different Pokemon
Not including Kanto Pokemon their are 235 pokemon in the National Dex. With Kanto Pokemon included their are 386 pokemon in the entire pokedex.
493
You get the Poke-radar when you get the National Poke-dex. To get the National Dex, you need to see, not obtain, all of the sinnoh regioon pokemon.
150 (and Manaphy, but you don't need to see or get it) in the Sinnoh Dex, and 493 in the National Dex. There should be 151 Pokemon in Pokemon Diamond.

The last Pokemon on the national dex is Arceus.
