Team Rocket's Meowth was supposed to be a special case who trained himself to walk on 2 legs, but then it became the standard for Meowth and now all Meowths are portrayed that way.
Same as Ditto keeping its face when transforming. It was just supposed to be one retarded Ditto, but now it's portrayed as the standard.
