The Dragon Lord
Kangaskhan-Programmed to breed, despite its eggs still having the baby inside of them
I've always looked at that as a game limitation, rather than an actual fact. Sort of like Pokemon that live in water being able float above land when battling. If the game were more advanced (or the programmers cared enough), then Kangaskhan would be depicted differently. A less limited media (such as the anime) would show it more like it was intended.
Nidorina and Nidoqueen-Not programmed to breed, despite Nidoran Female being breedable
This is one of the few things that I will admit makes absolutely no sense. Though it's more of a problem with game mechanics than actual logic.
Yeah, and still, Mew has the DNA of all Pokémon, can use Transform like Ditto does and yet, still can't breed.
Mew doesn't have the DNA of all Pokemon, it is the ancestor of all Pokemon, and its DNA eventually evolved (in a Darwinian sense) into the DNA of all Pokemon. Probably it being able to use Transform is more of a superficial change when compared to Ditto using Transform, which is why they breed differently.
