The Gamer from Mars will discuss the origins of the Pokemon Mew, Mewtwo, and Ditto. Update: It has come to my attention that in a recent interview with Game Informer, the Game Freak Staff have stated that they know nothing about this matter. Unfortunately, none of the men interviewed worked on the original games, so it's still possible that Ditto was originally meant to be a failed mew, but the idea was scraped in the development cycle.
