Tons of new Pokemon. But after you beat the elite four and go to the three other places that you couldn't before and there will be some old Pokemon from other regions.
Once you beat the Elite Four and N, you can access the Pokemon Transfer Lab on route 16(I think). If you have another DS or DSi with a Pokemon game that has one(or all) of the three, you can use the transfer lab to send them over to black.
theyre starter pokemon, you cant find them. you pick one of those three when you start your game
You have to have three different games for that to happen.
Trade for them.
You start your game and get 1 starter then trade it. Then start the game again and pick a different starter. Do the same until you get all of the starters from Pokemon black and white.
Nothing significant happens if you beat the Elite 4 three times in Pokemon Diamond, unless you include acquiring huge amounts of money and leveling up your Pokemon a very good amount.
tepig, oshawott, and snivy.
All of the elite four members have four Pokemon, in which you can fight them in any order. Three of each of their Pokemon are lvl 48, and each have one lvl 50. The types are phychic, ghost, fighting, and dark.
Yes, Squirtle, Bulbasar or Charmander are the three starter pokemon. You may choose to start with either of these three.
For the three shiny legendary dogs and the event Celebi go to Castelia and use the get the relocator. For everyone else, you have to beat the Elite Four in Black first. Then go over to Route 15 and go into the Pokemon transfer lab and talk to the guy at the end. There will be a very annoying mini game that you have to catch the Pokemon once you select the six you want to send over.
You cant its not possible to get them Melovepeas: ^that is incorrect. You cannot "find" the Three Lakes in Pokemon Black, as they're the legendary trio of the Sinnoh Region. It is possilbe, however, to migrate them from Pokemon Diamond/Pearl/Platinum to Black.
