No, Mine has a Sassy nature. :\
Well, you can always Pokesav it. But I do not think there is a code.
always be yourself even if your lonely :)
After a little while into the post game, Cresselia starts appearing into your dreams or at least Darkrai is. He was pretending to be Cresselia. Cresselia is really good, but the Cresselia in the dreams are Darkrai's doing.
I looked it up, you can get Cresselia, but it doesn't say how. It only says you can get Cresselia at Sharpedo Bluff.
lonely islands of poverty mean that people are always left lonely if poor in simple terms no one comes in times of need
Cresselia is always at a random spot on the map, and since every game is different, it is impossible to answer where Cresselia is next. You should get the Marking Map App for your Poketch, which gives the exact location of Roaming Pokemon (e.g., Mesprit and Cresselia).
If you are the only one in a group that likes certai thinks or acts a different way, you can feel lonely, but always be yourself.
you find cresselia on full moon island
no, cresselia can only be caught in gens 4+
Well, Ice beam for a Choice Specs Cresselia and Icy Wind for a Cresselia with high stats on defense
If Cresselia disappeared off of your map completely, then you have already caught Cresselia, or there is a glitch in your game where Cresselia has just disappeared off of your map. Further details would be needed for a more in-depth assessment as to why this has happened if neither of the two reasons stated are why Cresselia isn't on your map.
yes if you lower the hp enough. (clue cresselia always flees at the start of battle. use mean look or block to enable it you'll also want to use mean look again after 3 turns :).
