What are the rarest Pokemon in each region, that aren't Legendaries/only one Pokemon?

Such as Dhelmise in Alola, since it is only 1% in one place.(This does not count SOS exclusive Pokemon, and I’m talking about regular encounters, not Shaking/Bubbling/Dusty spots.) Thanks! Sorry if this is unanswerable/really long to answer. Also, if they have a remake game, find the rarest in all and specify which game.

Ok I remember almost everything he said in the video so I’m just gonna do this again.
