The Pokédex UI
A Pokédex is an item that displays a Pokémon's basic data, height, and weight. It contains a list of all Pokémon that the player has captured, and a brief description of each Pokémon. A Pokédex is useful for figuring out which Pokémon have been seen or caught.
By right-clicking a wild Pokémon with a Pokédex, the Pokémon will have its name and pictured entered into the Pokédex. To obtain the height, weight, and description of the Pokémon, it must be caught or otherwise obtained (i.e., trades, evolutions, commands).
If in Creative mode, a Pokédex lists all Pokémon up to Generation 5, even those that have not been implemented yet.
