Pokédex in HeartGold and SoulSilver

The Pokédex (Japanese: ポケモン図鑑 illustrated Pokémon encyclopedia) was created by Professor Oak as an invaluable tool to a Trainer in the Pokémon world. It gives information about all Pokémon in the world that are contained in its database, although it differs in how it acquires and presents information over the different medias. However, they are also only given to a few trainers at a time, generally to the ones that are felt to have exceptional potential and skill.

Pokédex entries are typically only two- or three-sentence bits of information about the Pokémon referred to. In some events it gives background information on the habitat or activities of this Pokémon in the wild; at other times it gives other bits of information on the Pokémon's history or anatomy.


In order to accomplish Professor Oak's goal of a complete database of information on every Pokémon, the Pokédex is designed to find and record data on each Pokémon the trainer meets. Pokémon are added to the Pokédex simply by encountering them in battle (or a few special exceptions in Gen IV, such as seeing a picture), but detailed entries are not recorded until the player catches the Pokémon or acquires it in a trade.


The main feature of any Pokédex are the entries on each individual Pokémon, which provide a lot of detail that would otherwise be unexplored in the games.

Generation I

The main interface of the first Pokédex model

In Generation I, the entries were simple and each individual section could be accessed directly from the listing. The first, and main part, was called Data, and included an image of the Pokémon, its number, name, species, Height, Weight, and a short blurb. The second part was called Cry, and selecting that would simply play the Pokémon's cry. The last part was called Area, and would display the map, along with flashing indicators at each location where the selected Pokémon could be found. In cases where the Pokémon was not available in the wild, was only available once, or could only be found by fishing or in Cerulean Cave, the message "Area Unknown" would be displayed over the center of the map instead. The Yellow version allowed players to print entries using the Game Boy Printer.

Generation II

Generation II retained the same elements as its predecessor, while adding the Pokémon's footprint to the information, and, like Yellow, allowing players to print entries. Unlike Generation I, selecting a Pokémon displayed the entry in a new screen from which the other sections could be selected. This became the norm for each subsequent generation.

Strangely, entries that would normally display "Area Unknown" on the map simply displayed an unmarked map.

Generation III

Generation III did not add anything to the main entry, however, Cry was given its own page, which would display the soundwave as it played. In addition, the Area section was changed to highlight locations instead of marking them and could now display the locations of Pokémon caught by fishing. A Size section was added, which displayed silhouettes of the Pokémon and the player character side by side.

FireRed and LeafGreen displayed entries in a much different format from Ruby, Sapphire and Emerald. It was the first Pokédex to actually display a Pokémon's type in its entry, as well as its box sprite. However, the Cry visuals were removed. Entries for Kanto Pokémon were taken from Red/Green for FireRed and Red/Blue for LeafGreen. Johto Pokémon entries were taken from Silver for FireRed and Gold for LeafGreen.

Generation IV

Generation IV added numerous features, but of FireRed and LeafGreen's changes, it kept only Type. Area would now change its highlight color depending on whether a Pokémon is found on land or in water, and the player could view the differences between morning, day and night, with the default being the current time. Cry's display returned, with a bar display in addition to the wave display, and the ability to modify the cry via Chorus/Pan, Reverb/Filter and Loop. Weight was added to the Size section, which put the Pokémon and the player character on either side of a balance scale. A new Forms section allowed players to see gender and form differences within species, but only for forms they'd already seen.

HeartGold and SoulSilver changed the formatting again, now by displaying the list on the lower screen and the actual entry on the top screen. Cry's page was again removed. By selecting to view details, players could view Area, Size and Forms. Area no longer defaulted to the current time or differentiated between land and water, Size now utilized both screens to display both Height and Weight at the same time, and Forms added a Compare option to see different forms side by side instead of having to scroll between them. Entries for Johto and Kanto Pokémon were taken from Gold for HeartGold and Silver for SoulSilver.

Search and Order

The original Pokédex had no search function.

In Generation II, the ability to search for Pokémon by type was added, as well as the ability to sort by New Pokédex mode, Old Pokédex mode, A to Z mode and Unown mode.

In Ruby and Sapphire, the search function was expanded to allow searches by name and color. Players were also given the option to order Pokémon by Heaviest, Lightest, Tallest, or Smallest. Two modes were available, Hoenn and National. National mode was unlocked via a trade with Kanto or Orre, or in Emerald, defeating the Elite Four.

However, in FireRed and LeafGreen, the search function was dropped altogether, instead choosing to expand the sort functions by adding lists of Pokémon by type and habitat. Heaviest and Tallest orders were also removed. National Mode was unlocked by completing a quest in the Sevii Islands.

Generation IV brought the Search function back, as well as Heaviest and Tallest orders. Habitat was dropped. Searches could now be conducted by Form, but not by Color. The two Pokédex modes were Sinnoh and National. National mode was unlocked by seeing every Pokémon in the Sinnoh Dex.

HeartGold and SoulSilver added the ability search by Height and Weight (instead of simply sorting by them), and also allowed search by Area (Johto, Kanto, or Unknown). National Mode was added by talking with Professor Oak after defeating the Elite Four.


Diploma awarded in Red/Blue

Completing the Pokédex is a common goal of trainers and carries with it much esteem due to its difficulty, which has gradually escalated with each new generation, as each has introduced at least 100 new Pokémon to be found. However, this is circumvented to a degree by the introduction of Wi-Fi and the GTS in Generation IV. The in-game rewards are always a congratulations from the director's avatar and a diploma, though in Emerald, the player could receive their choice of one Johto starter Pokémon for completing the Hoenn Dex.

In the Anime

Ash's Pokédex and stylus

When a young "Sammy" Oak was accidentally warped to a future of his own time, Ash explained to him how the Pokédex works, unknowingly giving him an idea. In The Evolution Solution it was mentioned that the Pokédex entries were written by Professor Westwood V of the Seafoam Islands. Unlike the games, entries in the anime are pre-programmed into the database and do not require catching to give full information. In this way, they act more as a aide or guide than a recording instrument.

To look up information on a particular species, trainers may simply point the Pokédex at an individual or manually enter it in. The Pokédex will then display a picture and read the entry out loud. It may also be able give more information on individuals, such as level and learned moves.

Trainers without the luxury of a Pokédex may have access to other means of finding information. Some use high-tech computers, like Giovanni in The Thief That Keeps On Thieving! or Shingo in Wired for Battle!. In several episodes, James uses a deck of cards.

In the Manga

The Pokédexes of the holders from the Emerald chapter

Pokémon Adventures

In Pokémon Adventures, it is seen that Pokédexes make a signal when brought close to one another, a sort of communication mechanism that can help locate others. This signal is only activated when held by their rightful owner, as seen in PS085. This signal seems to apply for all models of the Pokédex, as the Johto Pokédex Holders also had their Dexes beeping when they were united at the Whirl Islands, and the Hoenn trio in the Emerald chapter. Later within the same chapter, all ten Pokédexes made another signal after the previous five to be petrified in the end of the FireRed & LeafGreen chapter were restored. The Sinnoh Dexes had the same function as the past trios, but as they have yet to meet their predecessors, the same one seen when all users were brought together has not been seen since.

Much as in the anime, the Pokédex in Pokémon Adventures displays the known moves by an individual Pokémon, as well as its current health, but unlike in the show counterpart, the Dex Entries are usually taken directly from the games and as such contains readable text, cries, and area-tracking functions rather than vocal functions. The Pikachu interaction feature featured in Pokémon Yellow was added to Red's Pokédex, allowing him to see its mood (though he never is seen making much use of it, as Yellow was in possession of his Pokédex for most of the chapter, and could tell Pika's mood on her own anyway). The Pokédex's function takes over much of the control the games give to the player, being able to prevent a Pokémon's evolution, whereas Trainers without a Pokédex have no choice in the matter. As seen in Wanted: Pikachu!, the Pokédex can discover where a Pokémon was first met by its Trainer, much as the Gen III-added feature allows one to view a Pokémon's origin.

The Electric Tale of Pikachu

In the manga series The Electric Tale of Pikachu, Pokémon Trainers receive their Pokédexes when their application to become a Pokémon Trainer is accepted. A Pokédex contains information on a Pokémon's moves and abilities, as well as general information (such as how some Pokémon, like Pikachu, dislike Poké Balls) and the ability to tell if a Pokémon has critically low HP. In addition, all Pokédexes contain a copy of the Trainer's licence.

Updated versions of the Pokédex are released from time to time: in Clefairy Tale, Professor Oak gives Ash a beta version of the latest model of the Pokédex.

In the TCG

Pokédex HANDY910is

This listing is of cards mentioning or featuring the Pokédex in the Pokémon Trading Card Game. The Hoenn region's model did not receive a TCG card, and the Generation I and Generation II Pokédexes, which featured model numbers on the Japanese card, did not show these model numbers on the English card. Every card has allowed the player to look at a certain number of cards from the top of their deck and then either arranging them as they like, or in the case of Pokédex HANDY910is, choosing one to put in their hand.

  • For Two Degrees of Separation!, Professor Oak's lecture is about the Pokédex. He writes this Pokémon senryū about it: こまったら ひらいてみよう ポケモンずかん Komattara hiraite miyō, Pokémon zukan. "When troubled, let's open the Pokédex."
  • Most of the Pokédexes appear similar to one of Nintendo's handhelds. The Johto Pokédex resembles a Game Boy Color, the Hoenn Pokédex appears similar to the Game Boy Advance, the Generation III Kanto Pokédex resembles a Game Boy Advance SP, the Sinnoh Pokédex resembles Nintendo DS Lite, and the Generation IV Johto Pokédex is in similar appearance to a Nintendo DSi.
  • The Pokédex is evidently encased in material that is invulnerable to almost anything within reason. It has been soaked in water and (in the anime) electrocuted and exposed to high-temperature flames, all with no ill effect. It is also voice-sensitive. There are some limitations to its ability; certain circumstances can prevent the Pokédex from accurately identifying its target:
    • A Pokédex which has not received a National Mode upgrade will not display any information on Pokémon not usually found in its home region, even if those Pokémon have been caught.
    • Similarly, Gary's Pokédex failed to identify Mewtwo at the Viridian Gym, displaying only static interference. This may be attributed to the mechanical battle armor Mewtwo was wearing at the time.
  • All five of Ash's Pokédexes have been red, as were the Pokédexes in the games prior to HeartGold and SoulSilver, while other characters have had other colors. May had a yellow one in Kanto, Paul has a dark blue Pokédex, and Dawn has a pink Pokédex.
  • The Kanto regional Pokédex and the Sinnoh regional Pokédex (Diamond and Pearl) have 151 members, the smallest of all regional Pokédexes. The largest regional Pokédex is the Johto regional Pokédex, with 256 members.
  • The Pokédex models of Generations I and II rounded the weights of all Pokémon to full pounds except for Gastly and Haunter, despite the Japanese games' use of tenths of kilograms since the start. From Generation III onward, all weights have been given to the nearest tenth of a pound.
  • The Pokédex lost several buttons with every new model, due to various upgrades: Kanto's first model has twenty-two buttons, Johto's original model has five, Kanto's second model, Hoenn's, and Sinnoh's only have three, and Johto's second model apparently has none whatsoever, solely using the touch-screen interface.
  • Numerous toy Pokédexes have been manufactured by companies like Tiger Electronics and Jakks Pacific.
