it faints and disappears
In platinum it would be better not to kill mesprit uxie and azelf, it would be better to catch them.
Uxie doesn't run away. Mesprit does. So don't worry.
you get a 25 boost on stats .
mewtwo,mew,zcrom,lugia,uxie,azelf
i don't think anything happens.....
you head over to the spear pillar and catch or kill dialga
Yep. But you have to defeat the Elite Four and Cynthia first. Then you return to its cave.
I found it dificult but mespirit when he faints will just teliport to another place and for uxie and azelf you need to defeat the elite four and Cynthia then you can face them again.
You cannot catch them. However, you can still receive one in a trade - through a friend or over the WFC
little red pokeball shows up by them and u can use them in battles.
Yes, Uxie is capable of flying.
i will trade an uxie for your darkrai
