your starter has to be squirtle and you need to defeat the elite four
Lugia Ho-oH Riakou Suicune Entei
everywhere its a random encounter like latios,cressila,and mespirt
because you are an losser Look who's talking!
If you get squitle as your starter, once you get the national dex, it will be a roaming Pokemon
Zapdos, Articuno,Moltres, Mewtwo,Entei,suicune,and Riakou
That's not possible since you don't have the national dex.
