Hello. I've killed my Volcarona on Black2, cause I was following a walkthru that said that I could beat it and then catch it after beating the Elite 4. The thing is, I've beaten the E4, and Volcarona isn't there. What should I do?
Perhaps you've been to the wrong room? You can go and beat the Elite 4 one more time and try again.
