Is there someone l need to talk to or do to make Kyurem appear at the giant chasm in white 2?

Question

I have beat the elite 4 twice in Pokemon white 2 and went to the giant chasm to catch Kyurem but he is not there.

Answer 1

You need to catch N's Reshiram at Dragonspiral Tower first. To do so, head to Victory Road and maneuver until you see a Zoroark. The Zoroark will lead you to N'S Castle. Then, go with N to the top floor and battle his Reshiram. After defeating him, he will convert his Reshiram to a Light Stone and give it to you. Take it to Dragonspiral Tower and go to the top floor. Reshiram will then appear from the stone. Catch it. N will come by and say that Kyurem has returned.

Answer 2

If you do have kyurem in Pokemon black or white trade it to black/white 2 then trade reshiram/zekrom from black/white 2 then merge them together with the DNA splicer that Drayden gives you when you beat him in a gym battle. then you should get white/black kyurem!!!

Good Luck!

P.S: use master ball if you have one or get down to red life then catch it with another type of pokeball.
