They will run away, and you have to find them in the wild and capture them.
DONT!!!! if you run away from azelf or uxie, youll never battle them again.(unless you have a action replay) if they k.o. you, you can battle them again. if you k.o. them youll never battle them agian.(unless you have a action replay)
In Pokémon Diamond and Pearl, you only have one chance to capture Uxie. If Uxie faints or if you run away, then you will not get another chance to capture it. The answer is no.
Yes
After the events of spear pillar check out all of the lakes and battle uxie and azelf, Mesprit will run away Sargent Pickles response: I caught uxie but defeated azelf by accident and i tried like 20 pokeballs on uxie until i had to use my master ball it just would give in lol but u can catch it :)
Uxie is found in a cave at Lake Acuity.
you can't find Uxie again if you have knocked out Uxie, unless u defeat the elite four again.
after you catch dialga
you need to use surf. there will be a cave -like thing in the middle of the lake. go inside and you will find the legendary pokemon. if it is mesprit, it will run and you have to get poketch app markng map from jubilife city and track it down. you will find it in the wild and again, it will run. if it is uxie or azelf it will stay and battle you.
Uxie doesn't run away. Mesprit does. So don't worry.
