Pokemon Black 2 Cheats :
Secret - Zekrom Kyurem Black Kyurem
To get N's Zekrom, you will need to beat the game at least once. Do you remember where you found Zoroark but will not move? Well, now you should go back to the Victory Road and it wants you to follow it. When you follow Zoroark, you will see N's collapsed castle. N will be there. Reasons for him being there is unknown, but after you confront him at first he will join you. If you go to his room, he will tell you what happened 2 years ago or when he was a young child. He leaves the room, but he will still follow you once you leave.
I am unsure if there are any wild Pokemon in N's Castle, but keep on going until you see the center-most entrance where the old hero and N had their biggest battle in history. Once there, N will appear behind you and asks you if you're ready. His only Pokemon is Zekrom, but it is powerful otherwise. You will get to battle N, but this battle is deemed short. Once you beat N, you will acquire the Dark Stone from him. After all that, N will stand there in his castle alone. No one knows what would become of him, but it's going to be a waste of time if you insist on pestering him.
Take the Dark Stone to Dragon Spiral Tower to the top-most floor. Then the Dark Stone will become Zekrom again, where you will able to capture it. Once captured, Kyurem will be available in the Giant Chasm. Both of them will be at Level 70, so come prepared.
Remember the item that Drayden gave you when Opelucid City is frozen? This is one of the Link Pin that can be used to fuse Zekrom with Kyurem. It can also be used again to reverse the fusion. Once you used the Link Pin on Kyurem with Zekrom in your party, you will now have Black Kyurem, being the third strongest Physical Sweeper. Freeze Shock and Fusion Bolt will become available for Black Kyurem, however, Bolt Strike isn't available. Black Kyurem will have Teravolt as its ability.
