>>52391359The more I think about the more it's because some Pokemon simply shouldn't be able to breed in captivity or conventional methods, nevermind lay eggs. Greavard is supposed to be a dead dog, so if you breed a Greavard egg where did the dead dog come from? If Yamask is a human then how the fuck did two Yamask breeding create a dead human?
Basically, Gamefreak is sidestepping Pokemon fucking mainly so you can get eggs in gameplay while also having all this weird shit lorewise. So by this logic, ie nobody knowing what the fuck eggs are, feel free to imagine that the eggs from your Pokemon are from you fucking them.
