trade
the rarest Pokemon in Ruby Sapphire and Emerald is Feebas
in rout 114. with fishing.
you have to max out feebas happines and then level it up one level :DDD
Actually, it's impossible to catch Milotic in any Pokemon Game. But, it's possible to catch its pre-evolution, Feebas. To catch Feebas in Pokemon Emerald, there is a complicated way. But, I know that you can catch Feebas in Route 119. Hope I helped :)
you want catch it with the rod in rout 119.
supe rod
no
Feebas appears when fishing with an old rod in route 119 (extreme rare to the max but I got him in pearl).
You can't. You have to catch a Feebas & raise it into a Milotic.
it is pretty rare, but keep on trying
You can find Feebas along route 119 in Pokemon Emerald. Feebas is often over looked similar to Magikarp due to its dull wit and unattractive appearance.
