mostly legendary and your first pokemon you started out with but if you dont have legendaries , use high level pokemon -50 through 100-
You cannot trade Pokemon on from other games (unless it's Pokemon black/white) until you have defeated the elite four.
you have to beat the elite four on white and when you come out of the pokemon league, champion alder will come out too and give it to you
wifi battles battle subway dress up do elite four again link battle (if fiends have pokemon black or white)
you battle zekrom during the elite four after you beat all 4 of the people
After you beat the elite four you can catch it in the giant chasm there is also a legendary Pokemon in the giant chasm called kyurem.
Once you defeat the elite four you will find it. It is kind of hard to miss.
using the transfer machine found in either one of the generation V games after you defeat the elite four
you get zekrom in Pokemon white version and resheriham in Pokemon black.(in my oppinion, it should be the other way around, zekrom in Pokemon black, and resheriham in Pokemon white version) IT IS JUST LIKE PUTTING DIALGA IN POKEMON PEARL AND PALKIA IN POKEMON DIAMOND.
You have to have game cheats.Battle Elite 4.If you see Meinshao, use Master Ball.Thank you!-Chloe Sciuto
well actually this game isn't the same as the old Pokemon games. in the other games you beat the team and get the legendary before the elite 4 but now you have to beat the elite 4 and then you can get either reshiram or zekrom
pokemon white is hareder than pokemon black
Virizion? After defeat the Elite Four and obtained the National Dex, go to Pinwheel Forest and head far East. There should be a entrance and once you enter there would be Virizion.
