My name is Mike and I work as a Media Consultant for a UK Gaming Retailer. I got e-mailed this a few hours ago. I am convinced it's fake. I'm a Nintendo fan and a Pokémon fan so there is a part of me that wants to believe that this list is real, but there's no way to find out. I'm posting it online to see what others think of the alleged leaked Pokédex. Enjoy!
