Missing Number (Japanese: けつばん Ketsuban, lit. "Missing Number"), referred to by Nintendo of America as MissingNo., and appearing in-game as MISSINGNO. refers to a group of glitch Pokémon that act as fillers for vacant slots. For each version, there are 39 separate MissingNo. slots. Three particular examples also serve a specific purpose throughout the game; as the Kabutops Fossil, the Aerodactyl Fossil, and Pokémon Tower Ghost.

Most of the data pertaining to MissingNo. is clearly glitched and unintentional (and there is no error prevention, unlike for example the placeholder sprite loaded in place for the Generation III glitch Pokémon ??????????) and in itself MissingNo. is not a legitimate Pokémon, but curiously some data like nine of the MissingNo. cries are leftover development remnants. During the development of Pokémon Red, Green and Blue, the index numbers of many of the MissingNo. were instead occupied by unreleased Pokémon, but in the final games the leftover cries are the only hints that cut Pokémon ever existed.

The index numbers for "MissingNo." entries appear in between valid Pokémon, and combined they add up to 190 entries (151 valid Pokémon+39 MissingNo.). This was in fact an early number for the total number of Pokémon according to the 2020 Pokémon Blue source code leak, but it is also known that in total Game Freak have created even more draft designs of Pokémon/or any other monster designs pertaining to the Capsule Monsters pitch than 190, just not necessarily ever programmed into the game. One MissingNo. that doesn't exist in the final games may have also been replaced with Mew (hence hypothetically at this point in development, there were 40 MissingNo.; not 39). According to Iwata Asks (Pokémon HeartGold and SoulSilver), Mew was programmed into the game near the very end, after debugging features were removed to make space. At some point (as found by asset leaks) a cut Pokémon actually occupied Mew's index number (0x15, dec:21) as Omega.

While technically there can be 256 indexed species (2^8 entries in one byte), the other glitch Pokémon only exist after Victreebel (190) with names not programmed into the game but extrapolated from unrelated data beyond MonsterNames encoded as if they were Pokémon names. ('M (00)/3TRAINERPOKé₽ (00) can be interpreted as both the index 256 or index 0 Pokémon).

All MissingNo. are Pokédex number (family) 0, which is coincidentally the same Pokédex number as 'M (00). However, only (English versions) 'M (00)/3TRAINERPOKé₽ (00) are index number 0 (when distinguished from the Pokédex number, and some index number 0 Pokémon have non-0 Pokédex numbers, such as 176 for 3TRAINERPOKé₽).

MissingNo. is among the most well-known Pokémon glitches in the English player base, likely because it can be encountered through simple glitches and provide a means to duplicate items (see glitch Pokédex flags). It also typically but not always, appears identical to 'M (00).

Access and discovery

Coincidentally, both MissingNo. and 'M (00) are common with the left-facing shore tile glitch/old man glitch, and these were among the earliest known glitches in the English player base. In the English versions of Pokémon Red and Blue (unlike other versions like English Pokémon Yellow) the unused Bird-type also belongs to MissingNo. and 'M (00), meaning the Bird-type was an example of unused content in the Pokémon games known early on.

In the Japanese player base (where the left-facing shore tile glitch is impossible), the Select glitch (exclusive to Japanese Red/Green/Blue) and Trainer escape glitch (accessible in both Japanese and international versions but typically referred to as "fifth" in the Japanese player base), as well as move 0x00 corruption (all versions but easy to set up with Select glitch or Red and Blue using a move swap on an opponent with more than one move with Ditto and Transform), or unterminated name glitch item instant encounter (provided the front sprite is not problematic) are typically used in its place. In the Japanese player base, アネ゙デパミ゙ (FF) is also similarly well-known (in comparable popularity to MissingNo. and 'M), and can easily be seen replacing the first Pokémon with the dokokashira door glitch. The Japanese equivalent to 'M (00) is ィ゙ゃゾA (also Pokédex number 0).

In the French, German, Italian and Spanish versions, the left-facing shore tile glitch was partially patched in the Italian and Spanish versions of Red and Blue. The Italian and Spanish versions require using walk through walls on the coast instead of Surfing. In all versions of Pokémon Yellow, the old man glitch was also fixed. For the affected versions, this (and versions where MissingNo.'s front sprite freezes) made the accessibility of finding MissingNo. harder, but it can still be encountered with the Trainer escape glitch in all versions, and with Move 0x00 corruption (though it may require a trade for Pokémon Yellow, as the swapping Transform moves glitch typically used to obtain it as the first move was fixed there). Additionally, the Spanish and Italian versions have their own exclusive glitch for finding MissingNo. or 'M (00), which some native Italian and Spanish players have exploited.

Sometimes, specifically for Fossil and Ghost MissingNo. (182-184) because they bypass a freezing front sprite while still duplicating the sixth item, players for versions such as Pokémon Yellow (English) will use a sub-glitch such as the Ditto glitch or a chain of encounters when speaking with a trade NPC before returning to the route) to access Special stats as high as 182-184.

Acknowledgement by Nintendo of America

The earliest mention of MissingNo. by Nintendo of America was on the May 1999 issue of Nintendo Power where it warned that "any contact with it (even if you don't catch it), could easily erase your game file or disrupt your graphics". It was later featured among other support notes for Pokémon Red and Blue on the company's Nintendo.com website as early as 2000 (link), where it is described as a "programming quirk", "not a real part of the game", and "most often found after you perform the Fight Safari Zone Pokémon trick". However, the Japanese player base knew about MissingNo. before this.

Despite these official statements, MissingNo. is a relatively safe glitch Pokémon in English Pokémon Red and Blue, but other versions may feature problematic front or back sprites of non-fossil Ghost/MissingNo. that could potentially harm the save file due to a game freeze.

Details

Encountering a variant of 'Red/Blue regular MissingNo.' through the old man trick

The sprites and core data of MissingNo. varies between versions (Red/Blue, Yellow and each of their localizations, in addition to the Japanese Red/Green and Japanese Blue), but its Pokédex category is common across all variants, being classified as the "???" Pokémon. Some of the MissingNo. have sprites which may freeze the game (although not necessarily), such as the front sprite of regular MissingNo. in the English Yellow version.

The old man glitch is sometimes referred to as the "MissingNo. glitch", but this is misleading because MissingNo. is not the only Pokémon or glitch Pokémon that can be found with the glitch, nor is it the only glitch (or original glitch) for encountering MissingNo., however the old man glitch had lead to MissingNo. becoming well known in the West. The old man glitch is not present in Yellow or certain foreign language versions such as the Japanese Pokémon Red/Green, so MissingNo. cannot be obtained that way in those versions.

Upon catching MissingNo., its Pokédex entry will be shown if the player has not seen Cubone, and this will activate the Rhydon trap. Otherwise, the Pokédex entry will not be shown and the MissingNo. will not be turned into a Rhydon.

English MissingNo. have invalid mini-sprites that vary based on location.

MissingNo. unlike 'M (00) and other 000 family glitch Pokémon cannot learn any level up moves.

Obtaining MissingNo.

Below are methods of obtaining MissingNo. in different versions.

Note that additionally, MissingNo. can be seen and can duplicate items using the Cable Club escape glitch in all versions.

Pokémon Red & Blue (English)

  • Old man glitch:- if the character in the third, fifth, or seventh slot of the player's name is : the end-name marker, G, H, J, M, S, T, :, ], a, b, c, m, o, p, or v.

In the Spanish versions, it is required to walk on the shore tiles with walk through walls instead of surfing on it. While the old man glitch is possible the same way in the Italian versions, MissingNo. and hex:00 may freeze the game.

The glitch can be pulled off by surfing in the French versions, MissingNo and hex:00 also freeze the game at either a black or white screen.

  • Ditto trick/Trainer-Fly variation:- with one of the following Special stats (if the value is greater than 255, take a modulo 256): 31, 32, 50, 52, 56, 61, 62, 63, 67, 68, 69, 79, 80, 81, 86, 87, 94, 95, 115, 121, 122, 127, 134, 135, 137, 140, 146, 156, 159, 160, 161, 162, 172, 174, 175 or 181.
  • Remaining HP glitch:- with one of the following remaining HP values (if the value is greater than 255, take a modulo 256): 31, 32, 50, 52, 56, 61, 62, 63, 67, 68, 69, 79, 80, 81, 86, 87, 94, 95, 115, 121, 122, 127, 134, 135, 137, 140, 146, 156, 159, 160, 161, 162, 172, 174, 175 or 181.
  • Time Capsule exploit:- with Scizor, Shuckle, Heracross, Sneasel, Teddiursa, Ursaring, Slugma, Magcargo, Swinub, Piloswine, Corsola, Remoraid, Octillery, Delibird, Mantine, Skarmory, Houndour, Houndoom, Kingdra, Phanpy, Donphan, Porygon2, Stantler, Smeargle, Tyrogue, Hitmontop, Smoochum, Elekid, Magby, Miltank, Blissey, Raikou, Entei, Suicune, Larvitar, or Ho-Oh.
  • Arbitrary code execution e.g. with 4F/8F/etc. (for exploits involving glitch items, requires other glitches to obtain them, such as with the expanded item pack, dry underflow glitch, Celadon looping map trick).
  • TMTRAINER effect via '-' (move 0x00 corruption) (when sprites are not flipped).

Pokémon Red & Blue (Italian/Spanish)

Via evolutions

MissingNo. itself cannot evolve (through level-up, stone or trade) (unlike 'M (00)), however other glitch Pokémon can evolve into it.

  • Ditto trick/Trainer-Fly variation (fossil/ghost MissingNo. recommended to avoid a freeze, alternatively the "stable unstable MissingNo." method, or setting up a Trainer-Fly inside of the Pokémon Tower, encountering it without a Silph Scope, then altering the current map to a map other than Pokémon Tower to catch it without the Silph Scope with expanded inventory).
  • Remaining HP glitch:- with one of the following remaining HP values (if the value is greater than 255, take a modulo 256): 31, 32, 50, 52, 56, 61, 62, 63, 67, 68, 69, 79, 80, 81, 86, 87, 94, 95, 115, 121, 122, 127, 134, 135, 137, 140, 146, 156, 159, 160, 161, 162, 172, 174, 175 or 181.
  • Time Capsule exploit:- with Scizor, Shuckle, Heracross, Sneasel, Teddiursa, Ursaring, Slugma, Magcargo, Swinub, Piloswine, Corsola, Remoraid, Octillery, Delibird, Mantine, Skarmory, Houndour, Houndoom, Kingdra, Phanpy, Donphan, Porygon2, Stantler, Smeargle, Tyrogue, Hitmontop, Smoochum, Elekid, Magby, Miltank, Blissey, Raikou, Entei, Suicune, Larvitar, or Ho-Oh.
  • Arbitrary code execution e.g. with 4F/ws m/Pikachu off-screen glitch etc. (for exploits involving glitch items, requires other glitches to obtain them, such as with the expanded item pack, dry underflow glitch, Celadon looping map trick).
  • TMTRAINER effect via '-' (when sprites are not flipped).

Pokémon Red, Green, Blue (Japanese)

Pokémon Yellow (Japanese)

  • Above exploits from Red/Green/Blue except for those requiring Select glitches. For move 0x00 corruption, like English Yellow, the swapping Transform moves glitch does not work here so trading/other glitches to obtain move 0x00 as the top move may be required. The available arbitrary code execution methods in Japanese Yellow are different to Red/Green/Blue (Japan). The Fossil conversion glitch may still be possible if exploited from the expanded party (see also: international fossil conversion glitch).

Data

All MissingNo. are Pokédex number 000. and cannot learn any level up moves, unlike 'M (00) which evolves into Kangaskhan at level 0 or Clefairy at level 128, and learns Pound at level 136. MissingNo. typically have 'blank' cries; i.e. a Nidoran♂ (base 00)'s cry with a pitch of 0 and no echo, but nine MissingNo. have unique cries that were actually programmed into the game (see this section).

There are five 'forms' of MissingNo. in the English games. The first form is the 'regular' form, which there are 36 of. The second form is Pokémon Yellow's equivalent of the Red/Blue regular form.

All 36 'regular' and 'regular Yellow' MissingNo. use an invalid sprite. The other three forms are MissingNo.'s 'special' forms, which use the Kabutops fossil sprite from Pewter Museum (hex: B6 form), the Aerodactyl fossil sprite from Pewter Museum (hex:B7 form), and the Ghost MissingNo. sprite from ghosts in the Pokémon Tower (hex:B8 form), respectively.

In English Red/Blue, all 'regular' MissingNo. share the same sprite.

'Regular' Red/Blue MissingNo. data

All 36 regular Red/Blue MissingNo. are dual typed Bird/Normal Pokémon.

Their data is derived from Biker rosters; because the game uses extrapolation to work out the 'base' data for Pokédex number 000. For this reason, a lot of 'M (00)'s data is the same, because it shares the same Pokédex number (or 'family').

See this page for more information.

Starting moves

All 36 regular Red/Blue MissingNo. have the following starting moves:

Water Gun, Water Gun, and Sky Attack.

Learnset

All MissingNo. can learn no moves other than its starting moves, moves through TM/HM or through additional glitches/cheating such as the Time Capsule exploit, large storage box byte shift glitch, arbitrary code execution

Base stats

All have the following base stats:

  • Base HP of 33.
  • Base Attack of 136.
  • Base Defense of 0.
  • Base Speed of 29.
  • Base Special of 6.

TM/HM learnpool

  • TM01 - Mega Punch
  • TM02 - Razor Wind
  • TM03 - Swords Dance
  • TM05 - Mega Kick
  • TM06 - Toxic

  • HM01 - Cut
  • HM02 - Fly

Miscellaneous data

Red/Blue regular MissingNo. has a catch rate constant of 29, and Yellow regular MissingNo. has a catch rate constant of 0.

Red/Blue regular MissingNo.'s experience group is hex:1A. For this group, MissingNo. has a total experience of 345420 at level 100. In Yellow it is the hex:06 group instead, where MissingNo. will usually stay at Level 1 and has less experience at Level 255 than at Level 100.

Encountering this MissingNo. on the opponent's side or sending it out in battle will corrupt the Hall of Fame.

Due to an invalid Pokédex flag (#000, but essentially #256), MissingNo. (and 'M (00)) will increase the player's sixth item quantity by 128 if they do not have at least 128 items in that position.

MissingNo.'s base experience yield byte is 0x8F. Its base stats sprite dimensions are 8x8, while its actual front sprite dimensions are 13x13. Its front sprite source pointer is at 0x1900 and its back sprite source pointer is at VRAM:8F37.

Pokédex data:

RB Dex 1F.png

'Regular' Yellow MissingNo. data

'Regular' Yellow MissingNo.'s random front sprite commonly freezes the game, but when it doesn't, it may cause a multiple walking characters effect after exiting battle. Regular Yellow MissingNo. is a dual-typed Normal/Glitch (0x25) glitch Pokémon.

The corruption is caused by the source of Yellow MissingNo.'s front sprite, at 0x0006 in the ROM. Here the dimensions of Yellow MissingNo.'s front sprite are 0x0 which is apparently interpreted as a size of 256x256. However, in the base structure it is $AD (10x13). Yellow MissingNo.'s back sprite pointer is at 0x0D0C in the ROM where its dimensions are specified as 6x6.

Pokédex data:

Y Dex 1F.png

Miscellaneous data

Yellow MissingNo.'s catch rate is 0, but this does not mean it is impossible to catch it. Yellow MissingNo. needs an extremely large amount of experience to reach level 100 (16,136,684) but needs less to reach level 255 (13,582,671). It is part of experience group 0x06.

Its base experience yield byte is 0x0B. Its sprite dimensions in the base data structure is 10x13, but actual sprite dimensions are 0x0. Its front sprite source pointer is 0x0006 and its back sprite source pointer is 0x0D0C with actual sprite dimensions of 6x6.

'Special' MissingNo. data

'Special' MissingNo. take the appearance of either a Kabutops Fossil (hex:B6), an Aerodactyl Fossil (hex:B7) or Pokémon Tower Ghost (hex: B8) on the opponent's side, but they have no valid back sprite.

The two-byte backsprite pointer is instead taken from another Pokémon that was in memory. In Red/Blue the pointer if banked, is from bank 0x0B for MissingNo. 0xB6 (Kabutops Fossil) or bank 0x0D for MissingNo. 0xB7 (Aerodactyl Fossil, Pokémon Tower Ghost).

The starting moves, TM/HM learnpool, base stats and experience needed to level up for these Pokémon is based on the last Pokémon in the party except for another MissingNo. of the same kind. For a Trainer with an opposing special MissingNo., this data is taken from the last Pokémon they sent out.

A special MissingNo. will only corrupt the Hall of Fame if the player sends it out in battle.

Japanese MissingNo. data

The Japanese Pokémon games have at least 5 forms of MissingNo.; which are the previously mentioned 'special' (Kabutops Fossil, Aerodactyl Fossil) MissingNo. as well as Red/Green MissingNo., Japanese Blue MissingNo. and Japanese Yellow (Pocket Monsters Pikachu) MissingNo.

The Pokémon that occupies 'Ghost MissingNo.' in the Japanese versions however is not called "MissingNo." (unlike the localizations) but rather "ゴースト" (ghost) (not to be confused with "ゆうれい" (yuurei), used for Pokémon Tower ghosts in the final game.

Red/Green MissingNo. and Japanese Yellow MissingNo. can freeze the game on the opponent's side, while Japanese Blue MissingNo. appears to be stable.

In Pocket Monsters Blue, MissingNo. was given the placeholder Pokédex entry "コメント さくせいちゅう" (meaning 'comment to be written') and became the ??? species. This was not translated, resulting in a glitched Pokédex entry in the localized Pokémon Red and Blue and the corruption of MissingNo.'s original height and weight (1.0 m (3.3 ft) and 10.0 kg (22.1 lb), respectively), showing instead a height of 10.0 ft (3.1 m) and a weight of 3507.2 lb (1590.8 kg).

Cut Pokémon that became MissingNo.

Some of the cut Pokémon that became the 39 MissingNo. are known (currently 33 of them), as well as Omega, the potential additional MissingNo. that became Mew (0x15, dec:21). For further information, see here and here. Note that a few of these designs such as Kotora and Raitora were carried forward to Pokémon 2 and the Nintendo Space World 1997 demo (prerelease period of Pokémon Gold and Silver), but still never became final Pokémon.

Nine of them also have unique cries other than declarations of 0, 0, 0, (Nidoran♂ pitch 0 length 0). However, of those MissingNo. hex:45 has a cry identical to Zubat (formally it was a pre-evolution of Zubat), and MissingNo. hex:89 has a cry identical to Dragonair (formally it was similar to Gyaōn, or possibly a pre-evolution of it).

The original Pokémon behind 0x73, 0x79, 0x87, 0xB6, 0xB7, 0xB8 (if any), are unknown.

This section avoids discussing cut Pokémon where there isn't any evidence of them being tied to these particular MissingNo. in the index order, because Game Freak have created many more draft Pokémon designs than 190 during the decade Capsule Monsters/Pokémon and the early versions of Pokémon 2 (Pokémon Gold and Silver) were in development.

Other uses of the term 'MissingNo.'

MissingNo. is sometimes used as a general term for every glitch Pokémon, but this is a misnomer, as not all glitch Pokémon are called MissingNo., and MissingNo. is a placeholder name rather than an error handler per se.

In Generation IV, there is a sprite that reads 'missing number' (けつばん) in kanji (欠番) but it is not related to the glitch Pokémon MissingNo. and the name MissingNo. from Generation I.[1]
