Will Azelf come back if I knock it out in Black and White 2?

Question

I accidentally KOed it. Does it return?

Answer 1

If you accidentally run from or kill a legendary Pokemon, all you should need to do is beat the Pokémon League again for it to respawn. The legendaries will continue to respawn after beating the League until you catch them.
