The Diploma is an item received by completing a regional Pokédex. It is typically given by a Game Freak employee in the game. The diploma is not an item in the regular sense as it is not added to the player's inventory. To view it the player must talk to the person that originally gave them the diploma. The event Pokémon (Mew, Celebi, Jirachi, Deoxys, and Manaphy) are still not required to qualify for the diploma. In Generation IV, only seeing all the Sinnoh Pokémon will earn the diploma.
A separate diploma will be given for completing the National Dex in Generation III and beyond. The event Pokémon (Mew, Celebi, Jirachi, Deoxys, Manaphy, Phione, Darkrai, Shaymin and Arceus) are not required. Furthermore, unlike in Generation II, Lugia and Ho-Oh are regarded as event Pokémon in all games but Pokémon Ruby and Sapphire, and as such are not counted towards obtaining the diploma in those games.
In Pokémon Red and Green, it was long rumored that the player could obtain Mew from Game Freak's lead developer in Celadon Mansion after completing the Pokédex of 150 Pokémon. However, this is false; instead, a diploma is awarded for finishing the Pokédex.
