No.
You find them all at separate lakes. You can catch Uxie and Azelf at their lakes. Mesprit flees again when you go to her lake. You need to use the map marker poketch app to find it. PS: Don't fly towards the Mesprit. It will go to a different spot then. Use your bike or run to get to it.
After beating Cyrus on Mt. Coronet, surf to the caverns on the the three lakes. You can catch Uxie and Azelf here. When you meet Mesprit, it will flee. You will then have to run all around Sinnoh to catch it, and it will move if you fly. Hope that helps. the credit goes to maegirl77
Go to the three lakes and find the island in the middle sneak up behind them and paralyze or make them sleep then throw the ball with the highest catch rate you have and if they escape walk around in the closest grass and it will come to you.
You have to have the HM Surf, and surf into the middle of the lake. There will be an Island where you can catch either Azelf or Uxie (I'm not real sure) and they will be Lvl. 50. An Ultra Ball while they're asleep or poisoned or paralyzed will do the trick. But make sure you don't flee or knock 'em cold because you cant battle them twice. Hope this helps. :)
Azelf is in Lake Valor but,you must have faced Dialga to find it.If you have used your masterball already then I would say you may want an Action Reply Chip or Gameshark cheating device to get unlimited masterballs.If you do not have one,borrow one fro your friends.If you can't or none of your friends play video games or do not have a Action Reply Chip,do not despare.Try to stock up on as many different kinds of pokeballs and as many of them as possible.I would use the ball that gets stronger the longer the battle goes and save your game right before Fasing Azelf just incase you kill it or run out of pokeballs so you can just turn the game off.You can clone Azelf by putting it in the daycare center with a Ditto.Good luck.
Yes, Azelf will respawn, if you have fled or accidentally faint it, after defeating the Pokemon League.
No, Azelf will not come back in Pokémon Diamond once you have defeated it in a battle or you have ran from the battle. Mesprit, 1 of the 2 Pokémon that you encounter in a cave, it will flee once you interact with it but you will be able to run into it as you're walking across the region.
it is very hard to get azelf and mesprit and uxie. in my Pokemon diamond, azelf and mesprit fled the battle. if you want to find them, use your matching Pokemon app on your watch and DO NOT FLY UNDER ANY CONDITIONS. IF YOU FLY, THE POKEMON WILL ALSO FLY AND YOU WILL NEVER FIND THEM. DO NOT LOSE HOPE!!
When you catch dialga/palkia or defeat them, you can catch azelf and uxie in the lakes.Mespirit will flee so you gotta get a poketech radar to track it down.
Azelf will disappear from the game once you flee from it in Pokémon Diamond. It cannot respawn in Pokémon Diamond since that feature for Legendary Pokémon was not implemented at that point in time.
when they are in the lakes use a Pokemon with surf, there will then be an island in the middle, enter the island, the three possible Pokemon are azelf, uxie, and mesprit. you get one shot then they flee to a place on the map.
Its not Azelf its Mesprit that flees and you get it by using the Pokemon tracker app and you wil need a Pokemon with mean look so Mesprit does not flee.
Route 18
use your mouse to click flee...
Moltres, Articuno, and Zapdos all will continue to flee when you meet them, I'd consider using quick balls
If you're playing Platinum, then yes, Zapdos will flee, but in other Pokemon games, no. Zapdos is generally a stationary legendary Pokemon, so it won't flee after you attack and you can stay in battle as long as necessary.
After beating Iris, you first need to go to the Cave of Being which is found in Route 20 and you have to encounter Azelf, Uxie ad Mesprit there, they will then flee. After that, Azelf will appear in Route 23 provided you stand on a specific tile, the specific tile has stairs to the right of it in Route 23. Additionally 2 movable boulders that require the Strength HM can be found to the southeast of this specific file.
