The Point of Origin
Before I get the game I want to know how do you get the National Dex?
No I think seeing all is wrong because on multiple sites i've seen beat elite four to get natinal dex
Ok, to get the national dex, you need to SEE (not catch) all 150 pokemon of the sinnoh dex. heres a link if you care to look-http://www.serebii.net/diamondpearl/shinoudex.shtml
Now, its not that hard to see all of the national dex. all u have to do is verse as many trainers as you can during your adventure. the only pokemons i had left to see after beating the E4 was the lake trio (which i caught), and Diaruga (because i have pearl). You can see the other version's legendary by going to see the elder of the Kannagi Town after beating the E4.
THIS IS CONFIRMED BY ME, WHO HAS THE GAME. OK? I COULDNT GET THE NATIONAL DEX EVEN AFTER I BEAT THE E4, SO I FINISHED THE SINNOH DEX, AND GUESS WHAT? I GOT THE NATIONAL DEX!!!
