>>58425609There are certain spots you can consider "fixed spawn" alphas. There are certain spots where alphas spawn in some areas but aren't frequent enough. And any pokemon in a wild area can be an alpha of the same species in the regular spots the normal ones spawn naturally.
-Example of the first is the Houndoom in area 9 or the Pikachu in the same area. They are fixed to those spots and more often than not will spawn there at any time.
-Example of the second is Pidgeot in a rooftop where otherwise Pidgeotto and Pidgey spawn. It happen often but not always.
-Example of the third, Wild Area 1 can spawn Alpha of anything at any spot once the mechanic is unlocked, it also now has a fixed Alpha Pidget spot in the rooftop zone of it and the rare spawn Pichu can also spawn as an Alpha.
And shiny can stack with alpha pokemon.
