Depending on rare, there are actual rare Pokemon and Legendaries. There is a rare Pokemon about in every location and what I mean is by the low encounter rate. Legendaries can be found by certain interactions in different places. I suggest using Bulbapedia, Serebii, or Azurilland to find these Pokemon depending on the game you are playing, for some "rare" Pokemon can be common in other games.
you cannot catch wild rare Pokemon in xd but you can catch the trainers rare Pokemon, if they are "inpure"
If the Pokemon is extremely uncommon, then it is rare.
