Hi people I have obtained the national pokedex now, and I was wandering..

Thats a pritty open ended question. You can find all sorts of Pokemon after you get the national pokedex but I would sugest using the pokeradar and talking to dawns sister in Sandgem town she'll tell you about swarming Pokemon that you can catch and where and it changes every day. And if you havnt already go to the island by getting on a boat in snowpoint city. Then also try surfing the net and look for a site that will tell you what Pokemon you can catch and where and how and trust me there is a site that has all of it, but I can't remember the name sorry

You can go to serebii.net to get info but I know that togepi and eevee can be caught in that richs guys garden south of hearthome city.

Sinnoh Pokemon will be found in the grass all the time.

You can find new Pokemon on every route using the poke radar, just certain Pokemon are found on certain routes. Look here for more info: http://www.serebii.net/diamondpearl/poketor..

There are also Pokemon that will be found in swarms by talking to your rival's younger sistrer (in Sandgem Town). For more on this, look here: http://www.serebii.net/diamondpearl/swarms...

And there are some Pokemon that can be found on certain routes depending on which GBA Pokemon game you have inserted in your DS. Look here for more info: http://www.serebii.net/diamondpearl/gbapoke..

If you need help finding more Pokemon, look here: http://www.serebii.net/pokedex-dp Once you're there, you'll see that there are many ways to find any certain pokemon; by it's type, number (in order of the National Dex), breeding section, etc. Happy hunting! :]
