>>33622951I have to assume that Humans occupy their own egg group, probably just called the Human egg group, which would function as sort of a reverse Ditto egg group. As in, can only breed with others in the Human egg-group and nothing else. And attempting to breed something in the Human-Like egg group with a Human would be like trying to breed a Water 1 egg group with a water 2 egg group Pokemon. Similar, but not close enough to actually produce an egg.
>>33623231Probably something more similar to the former, depending on parentage. Like, if a woman got fucked by an Alakazam the offspring would likely end up with some egg moves from the Alakazam or some other traits. Maybe that's how you get the weirder trainer classes like Psychics and Hec Maniacs. If it were a female Pokemon getting fucked by a male human, the offspring would probably end up with some egg moves too, but not likely anything impressive or worthwhile.
