Yes , but first you have to defeat the elite four and champion again
you can catch azelf , mesprite and uxie before the 8th gym leader
Azelf is found in the Sinnoh Region, in one of the three caves in the middle of the three lakes. (Pokemon Diamond and Pearl). You can catch azelf after you catch the Pokemon Dialga or Palkia. It depends on the type of Pokemon game you have Pearl for Palkia and Diamond for Dialga.It would be best to catch Azelf with an Ultra ball. But if you havent used your master ball yet u can catch Azelf with that. Use Kricketune's false swipe, the use luxray's thunderwave to paralyze it. It took about 10 dusk balls.
On route 23
first:go to the place in the center of the map and catch palkia\dialga second:then go to any of the rivers and either mesprit,azelf,or uxie. third:go to valor lakefront for azelf. :)
Sadly, you cannot catch Azelf in normal Soul Silver gameplay. You can, however, trade it from a friend who caught it in a game in the Sinnoh region or you can use Action Replay.
you either killed him or didnt catch/kill palkia or dialga
Well, technically any pokeball will catch Azelf, eventually. A master ball would catch it on the first try, but if you have already used your master ball or would like to save it you can do what I did : buy 25 ultra balls, then go right in front of Azelf but do not talk to it. then save your game. now fight Azelf and get its HP down as much as possible. Then use all of your ultra balls. If you do not catch Azelf at that point turn off your game and start over. you will still have 25 ultra balls and Azelf will still be there. This may take several times but eventually you will catch it.
azelf is at route 23
Yes, but you have to defeat the Elite Four and the Champion again first.
You can't catch Azelf in Pokemon Heart Gold. Sorry! But you can catch it in Diamond, Pearl or Platinum. Hope this helps!
the way you catch azelf mesprit and uxie.
After you catch dialga you go to Valor Lake and use surf across it. Then you go in the cavern and azelf in inside it.
You must decrease azelf hp then try to catch it with 47 dusk balls and 47 ultra balls
You have to go to Lake Valor (south of Veilstone City) for Azelf. Azelf is a lot harder to catch than Uxie. I would recommend you to use Ultra balls. Keep Azelf's health as low as possible to throw Ultra Balls.
you have to go to lake verity cavern and catch it.
You cant catch it you need trade.
