In the Pokemon world, there are obviously some that are either female-only (the Chansey line, Kangaskhan, etc.) or male-only (the Hitmons, Tauros, etc.) In the wild, it's easy for females to breed since their offspring will always be of their own species. But what about the guys? How can they be so abundant in the wild when the only known way to continue their line is to find a Ditto somewhere, which don't even appear in most areas? Some, of course, have a female counterpart, like the Nidorans and Volbeat/Illumise, so they have a 50/50 chance for either gender. But for many others, notably the new Pokemon like Nageki/Dageki and Wargle, this isn't currently an option (unless I'm missing something concerning Vuljina). Any theories?
