Missingno. (Japanese: けつばん Ketsuban) is a dual-type Bird/Normal glitch Pokémon in Pokémon Red and Blue, and a dual-type Normal/999 glitch Pokémon in Pokémon Yellow. Due to the ease of which it can be found, it is one of the best-known glitch Pokémon.

In later generations, other glitch Pokémon are referred to as "a Missingno.", despite there being little relation to the one found in Pokémon Red and Blue or Yellow.

Missingno.'s cry is the game's equivalent of a "blank" cry: a Nidoran♂'s voice with a pitch of 0 and no echo. However, a few Missingno. have different cries, such as a Rhydon's cry.

The Pokédex entries of Missingno. and all glitch Pokémon with a Pokédex number of 0 will only appear upon capture if the player has not encountered Cubone, but as with all glitch Pokédex entries, they normally remain inaccessible through the actual Pokédex. An exception to this is in Red and Green, where Missingno. can be "registered"; in the Pokédex if the player enables the 'seen' flag for #152 through select button glitches and memory corruption. If Missingno.'s Pokédex data is viewed, it will consist of a very long string of glitchy sounds, much like ゥ .4 or h POKé's entries. However, unlike their entries, Missingno.'s does not lock up the game.

The leveling up learnset, base stats and types of the Kabutops fossil, Aerodactyl fossil and Ghost forms are the same as the Pokémon whose data was accessed last.

Forms

Normal form

Missingno. normal form has a sprite that is a strange block of glitched pixels in a backward-L shape. Due to the larger number of characters that can be used to make it appear, it is the most common form. Normal form is exclusive to Pokémon Red and Blue.

This form appears through the 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.
This form appears through the Mew glitch with a Special stat of 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.

Kabutops fossil form

Missingno. Kabutops fossil form uses the sprite of the Kabutops fossil found in the Pewter Museum of Science.

This form appears through the old man glitch if w is the character in the third, fifth, or seventh slot of the player's chosen name.
This form appears through the Mew glitch with a Special stat of 182.

Aerodactyl fossil form

Missingno. Aerodactyl fossil form uses the sprite of the Aerodactyl fossil found in the Pewter Museum of Science.

This form appears through the old man glitch if x is the character in the third, fifth, or seventh slot of the player's chosen name.
This form appears through the Mew glitch with a Special stat of 183.

Ghost form

Missingno. Ghost form uses the sprite of the Ghost found in Pokémon Tower if the player does not have the Silph Scope.

This form appears through the old man glitch if y is the character in the third, fifth, or seventh slot of the player's chosen name.
This form appears through the Mew glitch with a Special stat of 184.
This form apperars through evolving Z ゥ at level 224.

Yellow form

Missingno. Yellow form is Normal/999, whereas Missingno. forms in Pokémon Red and Blue are Bird/Normal. It uses the palette of Pikachu, and so appears as a yellow and red glitched box. It also causes glitches that Missingno. in Red and Blue did not. If caught, it will cause graphical glitches, possibly rendering the player invisible and making duplicates of the player and all other on-screen characters walk in random locations on the screen. Yellow form is exclusive to Pokémon Yellow.

This form does not appear through the old man glitch, as the old man glitch was removed in Pokémon Yellow.
This form appears through the Mew glitch with a Special stat of 31, 32, 61, 62, 63, 67, 68, 69 or 86.

Glitches caused

Examples of corrupted Hall of Fame entries

Missingno.'s appearance in-battle allows the item duplication glitch, which increases the number of items in the 6th bag slot by 128 unless the number of items in the slot already exceeds 128.

Encountering Missingno. has been known to interfere with the save game data in various ways, such as adversely affecting the Hall of Fame saved data and (if its stats are viewed) messing with some graphics until the stats of a normal Pokémon are viewed. When a Trainer battles with Missingno. in their party, both the Trainer sprite and their Pokémon's sprites will be scrambled, and all other sprites will be reversed. Viewing the stats screen of a non-glitch Pokémon will remove the effects.

Trading Missingno.

Missingno. can be traded from Red and Blue into Pokémon Yellow, but cannot be traded forward through the Time Capsule into Pokémon Gold, Silver, and Crystal. In Yellow, Missingno. levels down to level 1 if it gains any experience, and cannot grow any higher. The only way to use a Missingno. at a different level in battle is to use a link cable to battle between two games.

In the trade center, Missingno., due to its index number, appears as many different Generation II Pokémon from the perspective of Pokémon Gold, Silver, and Crystal, most commonly Tyrogue (due to the common name of ASH in Generation I). For a full list of the Generation II Pokémon Missingno. can appear as, see list of Pokémon by index number (Generation I). If the player tries to trade Missingno., a message will appear stating "Your <name> appears abnormal." and the trade will automatically be cancelled. Rarely, if a Missingno. is successfully traded, it will become the Pokémon it was said to be, and act normally (though it will retain any and all moves it had as a Missingno.). At this point, it only may be traded back into the Generation I game while the player is still in the Time Capsule (where it will again become a Missingno.), as if the player leaves, the Generation II game will detect it as a Generation II Pokémon and not allow the player to enter the Time Capsule.

In Pokémon Stadium

When viewed in Pokémon Stadium, Missingno. will appear as a substitute doll, while in Pokémon Stadium 2, Missingno. will show up as a Ditto, and if the game is saved via Stadium 2, will then become a Ditto permanently. Capturing Missingno. in the Game Boy Tower in Pokémon Stadium may cause the cartridge to become unable to be played with Pokémon Stadium.

Nintendo on Missingno.

Nintendo has an official description of Missingno. listed in their Customer Service troubleshooting section:

"MissingNO is a programming quirk, and not a real part of the game. When you get this, your game can perform strangely, and the graphics will often become scrambled. The MissingNO Pokémon is most often found after you perform the Fight Safari Zone Pokémon trick. To fix the scrambled graphics, try releasing the MissingNo Pokémon. If the problem persists, the only solution is to re-start your game. This means erasing your current game and starting a brand new one." ^[1]

Nintendo was incorrect on the method for fixing graphical issues; releasing Missingno. does not fix the graphics. The actual way to fix these issues is to view the Pokédex data or stat page of a hybrid glitch Pokémon or official Pokémon.
