I apologize for the long delay in getting this out. I hope this marks my return to a regular update schedule.
It is amazing that a creature which had survived unchanged for hundreds of millions of years could be nearly wiped out in the wild by man in the space of a few hundred. It is even more amazing that such a creature could be thoroughly domesticated, to the point where Totodile today are a friendly and docile pokemon which have changed so much from their wild forebears that they are properly considered a separate species – T. domesticatus. And yet through the power of artificial selection, Totodile are today among the most common pets in Johto.
Man has created not one species of Totodile, however, but two. For while most Totodile were bred for docility, there were those who saw in the species the seeds of a ferocious, amphibious warrior and bred them to that end. And it is these Totodile which survive in the wild today; indeed, it is their final form of Feraligatr from which we get the term "feral".
The feral Totodile, for all their skill in battle, were simply too hard for their trainers to control. The decision was made to release them all into the wild, for their breeders could not bear to destroy their own creations; perhaps it would have been kinder if they had. The new Totodile and their evolutions went after their prey with complete determination, even chasing pokemon such as Marill and Bidoof onto the land to devour them. The ancient Totodile, who had always waited for their prey to swim by and survived because they always eventually did, never stood a chance.
