Feebas Evolution

[acetrainer08]

Does Feebas really have to have a certain nature in order for it to evolve?

Not really. But there are 4 natures it shouldn't have.

EDIT: I'm REALLY not sure, but based on the 4 natures recommended (Modest, Mild, Rash and Quiet), I would say it shouldn't have Adamant, Impish, Jolly and Careful.

No, all it needs to do is have maximum Beauty from Blue Pokeblock or Poffin and then Level Up. But, some Natures will make that easier and some make it harder.
