Catch 'em all
You can not catch any of them in black or white, but I think that you can catch all 3 in diamond.
you can catch water Pokemon by surfing on water and by using all the rods
no but if you catch all the hoenn pokemon you can catch jotho and kanto pokemon
catch all 150 original Pokemon i believe if not its you have to catch all of them from the hoen region too
It is not possible to catch all Pokemon on one game, however, you can obtain all of them by trading and cheating.
It is possible to have caught all 649 eventually.
It is a long and hard proccess, but if you are a PokeGeek and you put your heart to it (like me) it is very possible. You have to catch all of the wild Pokemon, legendaries too, trade from other games, restart games, etc. But with about 3 Pokemon you HAVE to cheat. Otherwise it is very possible if you take them one at a time.
There are a lot, so i cant tell you them all, but i will tell you there is a lot.
You must defeat the elite four and the Pokemon champion then catch all the Pokemon which is only possible with help from friends.
catch it
Catch 'em all
well in Pokemon diamond it can be possible to catch all of them but the easiest ones are dialga,shaymin,mesprit,and the other two lake Pokemon i cant remember the names.
YES!!!!!!!! all you have to do is see all the Pokemon and catch the ones you can catch in the game!!!
No to get Cyndaquil you must catch all Pokemon from that region, because if you have to catch every single Pokemon, won't you already have Cyndaquil?
There is a way but it is hard.(this is only possible if you mean only Pokemon from 1 region) First you must catch the most Pokemon that you can find (no doubles) and then you must trade from other games to get the Pokemon that you can't catch in your version
if you don't have that Pokemon just catch it and evolve it
