Pokémon Kanto Handbook by Katherine Noll is a handbook that was published in 2005 and is one of the sequels to The Official Pokémon Handbook. It served as a paper form of the Kanto Pokédex from FireRed and LeafGreen, and was released as an update of the original Official Pokémon Handbook in concordance with the remakes. It contained an entry for all the Pokémon in the Kanto Pokédex. The front cover has pictures of two of the final evolutions of the starter Pokémon (Charizard and Venusaur) that one can choose from in the remakes of the Generation I games.
