Beat the Elite Four and then you talk to N and Zekrom comes out of the Dark Stone. You have to catch it to battle N, so bring lots of Ultra Balls! After you catch it, you have to fight N and Ghetsis.
Any Pokemon could defeat Zekrom, but Dragon and Ground-Type are especially effective.
You can catch Articuno on seafoam island whenever you don't have to beat the Pokemon League.

First of all you have to find N in N's Castle, a Zoroark will guide you there. You will battle N. When you beat him Zekrom will turn into the Dark Stone and you have to take it to Dragonspiral Tower. Catch Zekrom and then go to Giant Chasm. Kyurem will be there.

All you need to do is get all eight badges and defeat the Pokemon League. But, you can decide your goal to beat the game. You still have to beat the Pokemon League, but afterwards you can decide on your goal. Your goal could be to catch all Legendaries of that game. You goal could be to catch a number of Pokemon. But, the true way to beat the game is to beat the Pokemon League.
In Pokemon black, you can't get Zekrom, but in white, just beat the elite four, and then you'll be walked through the storyline, and then you have to catch a level 50 Zekrom. Make sure you bring some pokeballs before you enter the elite four!
You find the extremely strong pokemon after you catch Reshiram or Zekrom in either game. There is a place you couldnt go in the city were you beat the dragon dude and after you catch either pokemon and beat N there are like level 50s and 60s
