More detailed information is available after the player obtains a member of the species, either through capturing the Pokémon in the wild, evolving a previously captured Pokémon, hatching a Pokémon egg (from the second generation onwards), or through a trade with another trainer (either an NPC or another player). This information includes height, weight, species type, typing, and a short description of the Pokémon. Later versions of the Pokédex have more detailed information, like the size of a certain Pokémon compared to the player character, or Pokémon being sorted by their habitat (so far, the latter feature is only in the FireRed and LeafGreen versions). The most current forms of Pokédex are capable of containing information on all Pokémon currently known. The GameCube games, Pokémon Colosseum and Pokémon XD: Gale of Darkness, have a Pokémon Digital Assistant (P?DA) which is similar to the Pokédex, but also tells what types are effective against a Pokémon and gives a description of its abilities.
