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.
tepig, oshawott, and snivy.
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.
Yes, Squirtle, Bulbasar or Charmander are the three starter pokemon. You may choose to start with either of these three.
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.
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.
Get another black or white like a cousins or friends. Then you start three new games and each one with each starter and trade the first two to the other black or white and on the third on you trade them back to have all three
