Remnants of unused Pokémon have been found in the Pokémon games.

Generation I


The Missingno. occupy 39 index numbers in between the index numbers of valid Pokémon.

It is believed that the existence of the Missingno. (although having unintended glitch characteristics) may suggest Game Freak did (or intended to) work with additional Pokémon in Generation I, because Shigeki Morimoto is said to have confirmed (according to a Smogon thread by Zog) that 190 Pokémon were originally planned for Pokémon (with the rest being added later), and the value 151+39 equals 190.

Supporting this theory is the fact that nine Missingno. have special cries.

0x43's cry sounds identical to Zubat. 0x51's cry is comparable to Pidgey and Ditto.

Though speculation, 0x43 has been compared to Togepi, and 0xB5 has been compared to Crobat.

0x5E, 0x5F and 0x89's cries are comparable to the Dratini evolution line (note that there is an unused Pokémon design for a Pokémon that looks like Dragonair).

The cry data can be found in the table below, and can be listened to on the Pokémon Red and Blue TCRF article.

Index Number Hexadecimal Identifier Base Cry Cry Pitch Cry Length
67 0x43 0 128 16
69 0x45 29 224 128
79 0x4F 34 255 64
81 0x51 14 224 96
94 0x5E 15 64 192
95 0x5F 15 32 192
127 0x7F 17 32 16
137 0x89 15 64 128
181 0xB5 29 0 128

Generation III


Unused cries for two Pokémon were discovered in Generation III. These can be played as cries 266 and 269 in a leaked development version of German Pokémon Ruby known as "Debugging Version 0509A".

It is unknown whether these cries were intended to belong to Shellos and Gastrodon.

(In the May 2007 edition of the now defunct magazine Nintendo Power, Junichi Masuda commented that the development team were unable to put Shellos and Gastrodon in Pokémon Ruby and Sapphire but they were able to put them in Pokémon Diamond and Pearl.)

Generation IV

This section is incomplete, please feel free to add any missing information about the subject. It is missing: {{{1}}}.

Hidden within the code of Diamond and Pearl is an unused backsprite presumably belonging to Gastrodon, along with one for Shellos.

The Shellos backsprite is pink like West Sea Shellos, but has the 'wings' belonging to East Sea Shellos.

The unused Gastrodon backsprite looks like the final Gastrodon except it is missing the yellow stripes and 'flaps' on its head. Instead, its head has five bumps on it.

Additionally, the unused 'Gastrodon' backsprite has a different protrusion pattern on its back. There are three visible bumps on its sprite instead of the final backsprite two, and the three bumps have surfaces which are 'flattened out', unlike the final version which has rounder bumps.

Along with the backsprites for Shellos and Gastrodon, there are a multitude of other sprites, belonging to Treecko, Torchic, Mudkip, Ralts, Kirlia, Gardevoir, Turtwig, Chimchar, Piplup, and Manaphy.
