Pokédex, Dexter/Pokémon Bestiary

Japanese VA:  Miki Shinichiro (first series), Hayashibara Megumi (Advanced Generation)
American VA:  Eric Stuart

The Pokémon Bestiary is given to Satoshi and Shigeru at the start of their journey. It is basically an electronic encyclopedia of Pokémon, telling a trainer what type of Pokémon a trainer may encounter, its attacks, its stats, where it can be found, and any other useful information. 

There have been several different Bestiaries seen in the animated series. The first one was the Bestiary given to both Satoshi and Shigeru in Masara Town and contains information on the first 150 Pokémon. It later got an upgrade that included information on a few of the Gold/Silver Pokémon, such as Togepy and Maril. Satoshi's Bestiary got a full upgrade, with information on all the Gold/Silver Pokémon (totalling 251 pokemon), right before he started his journey in the Johto Region. His Bestiary's most recent upgrade included information on the new pokemon that can be seen in the Hoen Region. As more and more Pokémon are discovered, you can be sure that there will be upgrades to the Pokemon Bestiary to go along with them.
