Zekrom's catch rate is high enough that lowering its health and using a Dusk Ball or an Ultra Ball should take less than 10 balls.
Kyruem is pretty hard to catch unless you didn't use your Master ball to catch Zekrom, I caught Zekrom with a Quick ball.
Zekrom, and the best way to catch it is to keep your master ball and catch it that way, cause that's how I did it.
Either catch it with the Master Ball you received in Pokémon White or trade it with someone over the GTS.
you beat all 8 gym leaders and then you are required to go to N's castle. when you go there, in pokemon black, N is standing there with Zekrom and reshiram appears. you catch reshiram with a master ball. that's why professor Juniper gave you a master ball. If you're playing pokemon white, N is standing there with Reshiram and Zekrom appears. You catch it with the master ball professor Juniper gave you. if you already used it, then you just have to battle it out old style.
no
the master ball is for zekrom in white and reshiram in black
Well i lowered it's HP and caught it with a Ultra ball. I used my master ball on Kyurem. That dude is SOOOOOOOOOOOOOOOO hard to capture because it has a low catch rate. I caught it with a quick ball on the first turn. >poke master 3
I'm not quite sure what your talking about, but I would have to say that you would not have to catch it in a Master Ball.
Yes
No. Once you beat the Elite 4 you have to go into N's throne room. Zekrom will appear. Your best option would be to use the Master Ball to catch it.
you need to have two master balls.
you just defeat the the elite four and champion again and wella. ps.i recomend using a master ball
