You can't catch a Black Kyurem but you can get Zekrom by defeating N at N's Castle. After you beat him he will give you the Black Orb. Take the Black Orb to the top Dragonspiral Tower (which is is Iccarus city) and you'll see a really cool scene as Zekrom come out of his orb. Then after you've captured Zekrom you can goto the Giant Chasm and return to the place where you fought Black Kyurem and Ghetis and Kyurem will be waiting there. After you've captured Kyurem a poke ball will appear. Pick it up and inside will be the DNA Splicers. After that goto the key items in your bag and click on the DNA Splicers and pick use. Click on Zekrom and Kyurem and they will fuse in Black Kyurem. Its another form of Kyurem so if you un fuse them Kyurem will be at the level you got the Black Kyurem up to will be that level and the Zekrom will be at the level you fused it at. E.g: If you fuse the Kyurem and Zekrom when they're both level 70 and get the Black Kyurem up to level 85, when you un fuse them the Kyurem will be level 85 and the Zekrom will be at level 70. Hope this helps!
You can't make it transform in Pokemon Black, only Black 2 or White 2.
no just one or the other
i'm sorry to say that you can't catch black kyuram in black and white. i've tried every way i can think of. but you can get it in black 2 and white 2.
Black Kyurem is in Pokemon Black 2.
actually, you need to get zekrom to get kyurem
There are lots of different things to do at that point in the game, but the next place you are directed to is the Cave of Being on route 20, to start the hunt for the lake trio from Diamond and Pearl.
You cannot catch Rayquaza in Pokemon Black 2.
Yes, you would be able to trade your Reshiram from Pokémon Black over to Pokémon Black 2 in order to get White Kyurem however you will still need to catch Kyurem in the Giant Chasm but you won't be able to do that until you catch Zekrom in Pokémon Black 2 in the Dragonspiral Tower after defeating N in his Castle.
You would need to trade for them from Pokemon Black or White, for they are not available in Pokemon Black 2.
In the new pokemon black and white version 2, in the main story, something happens by accident and kyurem fuses with reshiram if you're playing pokemon black, but fuses with zekrom in pokemon white.
Technically, this move is hidden within the game and so NO pokemon can learn it, including kyurem. However, it is highly speculated that kyurem will be able to learn it in Pokemon Black 2 and Pokemon White 2.
no
