You can get them at the lake's. they are lake verity lake valor and something else. mesprit is a roaming pokemon, which means that it roam's around sinnoh, and you can track it's location using the marking map pokeketch app.
No... so sorry. Next time SAVE before you try to catch a legendary being that you can't see again if you defeat it. You won't ever get Uxie unless you trade. But at least Uxie was registered in your pokedex.
You go to them, save, and turn off your game until they are shiny. Unless you want to turn off your ds about 24,000 times, I would recommend just living with having unshiny Uxie, Azelf, and Mesprit. By the way, Mesprit is so hard to catch anyway that it would be incredibly rare to find a shiny one.
Put it simply, you can't
beat the elite four and the champion
Yes, it will be gone; one can only meet it once. Make sure you have everything you need beforehand, and don't forget to save!
Uxie, Azelf and Mespret, but you have to find Mespret in tall grass.

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.
you cant once you ran you cannot find uxie again
You find Uxie in the cave in the middle of Lake Acuity.
After finding Mesprit, Azelf and Uxie in Pokémon Black 2, things you will be able to do would be going to N's Castle in order to battle him and defeat his Zekrom. Another option is taking the Dark Stone after beating N to the Dragonspiral Tower in order to reawaken Zekrom in order to attempt to catch it. Other options would include attempting to catch Cresselia, Heatran, Regirock and Regigigas.
Uxie doesn't flee from you, you must be thinking about Mespirit.
You cant find Uxie now because he turned into a Bidoof and ran away
