You find Uxie in the cave in the middle of Lake Acuity.
yes just do what you do to catch Pokemon at acuitys cave
you need azelf,uxie,mesprit to open the cave after beating the Pokemon league
After you release Azelf, Uxie and Mespirit from the Team Galatic HQ, go to Lake Acuity. Surf across to the cave. Talk to Uxie to start the battle.
soon after you get palkia they are in each of the lakes in a cave
Uxie is in Lake Acuity after you catch Palkia. Go to Lake Verity first, go into Mesprit's cave, and the Professor will talk to you and you will be able to catch Azelf and Uxie. ~Lucario
Go to Lake Acuity with a Pokemon with Surf. Surf to the Middle of the Lake and go into the Cave. Uxie is in there (Lake Acuity is up North by Snowpoint City)
i don't know but it has to do with the 3 Pokemon UXIE MESPRIT and AZELF and DIALGA
Uxie is found in a cave at Lake Acuity.
uxie is at the end of steam cave
Those are nothing, but they look suspiciously like Mesperit, Uxie, and Azelf.
some say you can catch dialga in the celestic cave, that's how i got him.
on Pokemon yes after you beat the electric gym leader you then can find uxie or mespirit or azelf in the cave
