When Mew was first revealed there was a rumor going around at my school saying that it was unique because it had the power to devolve Pokemon.
Honestly I wouldn't mind if such a thing were possible. You catch an evolved Pokemon, then instead of breeding it to get its pre-evolved form in the dex you reverse the evolution. Heck, they could even use it in the anime to show just how powerful Pikachu really would be as a Raichu for a couple of episodes before returning to being a Pikachu.
Wouldn't that be too much like Digimon though?
Speaking of which, I used to think Digimon was related to Pokémon when I was a kid. They're both Japanese in origin and have to do with monsters who are used as pets and in battle, and they both have 'mon' at the end. I used to think that the main orange lizard Digimon was Charmander or a baby Charizard. XD
