you cant unless u tade but someone else says if you defeat the elite four they come back even if u defeat them i dont know if its true or not hope it helped
The rare Pokemon which you can get before the Elite Four in Pokemon Platinum are Giratina, Mesprit, Uxie, and Azelf.
They will run away, and you have to find them in the wild and capture them.
in platinum the different sprites are UXIE,MESPRIT and AZELF
You can't, you will need to trade them from Pokemon Diamond, Pearl or Platinum.
Uxie, Mespirit, and Azelf are unavailable in Pokemon SoulSilver. They can, however, be traded from a Diamond, Pearl, or Platinum game, or transferred from a Gen III game.
Azelf is in lake Valor near Pastoria city
nothing cause it's gone
at the lakes
in the scert room
No
Yes, you can get Azelf back if it faints during your challenge against it but it will only come back in Pokémon Platinum, Pokémon Black 2 and Pokémon White 2, it will come back once you beat the Champion regardless of whether you've already beaten the Champion or not. However if you've knocked out Azelf in Pokémon Diamond or Pearl then it will not come back.
Use your master ball.

You can't catch Azelf in Pokemon Heart Gold. Sorry! But you can catch it in Diamond, Pearl or Platinum. Hope this helps!
