'''Missingno.''' ([[List of Japanese Pokémon names|Japanese]]: '''けつばん''' ''Ketsuban'') is a {{2t|Bird|Normal}} [[glitch Pokémon]]. Because it is easy to access, it is the best-known of all the glitch Pokémon.
'''MissingNo.''' (Japanese: '''けつばん''' ''Ketsuban'', lit. "missing number"), as it is displayed in-game due to the ten-character limit in Western [[Generation I]] games, is a dual-type {{2t|Bird|Normal}} [[glitch Pokémon]] in {{game|Red and Blue|s}}, and a dual-type {{t|Normal}}/randomly named glitch type (which often has '9' in it) [[glitch Pokémon]] in {{game|Yellow}}. It is arguably the best known glitch Pokémon, closely followed by [['M (00)]], and it is the easiest glitch Pokémon to find in the localizations. It has five distinct forms, but the most frequent forms (the Red/Blue and Yellow normal forms) share 36 index numbers each.


Some other glitch Pokémon, even in later generations, have been referred to by people as a "Missingno."; however, these aren't related to the Red/Blue Missingno. in any way, except possibly by way of sharing its designated number of 000.
In later generations, other glitch Pokémon are sometimes referred to as "a MissingNo.", such as {{?|10}}, {{gp|?}}, and [[-----]]. Despite this, the name "MissingNo." is a misnomer in this case; they have little relation to the one found in {{game|Red and Blue|s}} or {{v2|Yellow}}.


==Biology==
MissingNo.'s [[cry]] is generally the game's equivalent of a "blank" cry: a {{p|Nidoran♂}} (base 00)'s cry with a pitch of 0 and no echo. This is because the cries of these Pokémon are undefined in the data structure. A few MissingNo. have different cries (specifically <tt><b>0x43</b></tt>, <tt><b>0x45</b></tt>, <tt><b>0x4F</b></tt>, <tt><b>0x51</b></tt>, <tt><b>0x5E</b></tt>, <tt><b>0x5F</b></tt>, <tt><b>0x7F</b></tt>, and <tt><b>0xB5</b></tt>). The fact that these cries are valid and not garbage data (i.e. unrelated data read in the wrong way, as is the case with most of MissingNo.'s properties) supports the view that MissingNo. may have originally been a Pokémon that was deleted from the games. (See [[:#MissingNo. as deleted Pokémon|this section]] for further details).


===Physiology===
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 {{p|Cubone}}, but as with all glitch Pokédex entries, they normally remain inaccessible through the actual Pokédex. An exception to this rule is in {{2v2|Red|Green}}, where MissingNo. can be "registered" in the Pokédex if the player enables the 'seen' flag for #152 through [[select glitches]] and memory corruption. If MissingNo.'s Pokédex data is viewed, {{p|Rhydon}}'s cry will be heard, followed by MissingNo.'s (blank) entry and a series of glitchy sounds.
Missingno. has four well-known forms. For its alternate forms, a specific letter must be present in the player's name as the third, fifth or seventh character. The specific letters are put in the description of each form.


Its most common appearance is its normal form, a box of pixels in a backwards 'L' shape that is similar to the shape of a {{wp|Tetris}} piece. This form will appear if G, H, J, M, S, :, ], a, b, c, m, o, p, v are in the third, fifth, or seventh slot of the player's name, making it the most common form due to the default name of '''ASH'''.
No MissingNo. can evolve or learn any moves through leveling up.


A second form shares the sprite of the {{p|Kabutops}} fossil found in the Pewter Museum. It appears in two ways:
If the {{gameabbrev1|RB}} MissingNo. is traded to [[Generation II]], it will hold a [[Carbos]].


# If a lowercase 'w' is present in the player's name in the third, fifth, or seventh slot while performing the [[Old Man Glitch]]
==Forms==
# If a player does method #3 of the Mew glitch with a Pokémon which has a special stat of 182
==={{v2|Red and Blue|s}} normal form===
[[File:Missingno RB.png|thumb]]
MissingNo.'s Red and Blue normal form is a dual-type {{2t|Bird|Normal}} glitch Pokémon. It 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 {{game|Red and Blue|s}}.
* 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 {{stat|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.
* This form can be obtained through the [[Time Capsule exploit]] if the [[trade]]d Pokémon is {{p|Scizor}}, {{p|Shuckle}}, {{p|Heracross}}, {{p|Sneasel}}, {{p|Teddiursa}}, {{p|Ursaring}}, {{p|Slugma}}, {{p|Magcargo}}, {{p|Swinub}}, {{p|Piloswine}}, {{p|Corsola}}, {{p|Remoraid}}, {{p|Octillery}}, {{p|Delibird}}, {{p|Mantine}}, {{p|Skarmory}}, {{p|Houndour}}, {{p|Houndoom}}, {{p|Kingdra}}, {{p|Phanpy}}, {{p|Donphan}}, {{p|Porygon2}}, {{p|Stantler}}, {{p|Smeargle}}, {{p|Tyrogue}}, {{p|Hitmontop}}, {{p|Smoochum}}, {{p|Elekid}}, {{p|Magby}}, {{p|Miltank}}, {{p|Blissey}}, {{p|Raikou}}, {{p|Entei}}, {{p|Suicune}}, {{p|Larvitar}}, or {{p|Ho-Oh}}.


Missingno. also has a skeletal form, with the sprite of the {{p|Aerodactyl}} fossil found in [[Pewter City]]'s museum. It's obtainable in two ways:
==={{v2|Yellow}} normal form===
# If a lowercase 'x' is found in the player's name in the third, fifth, or seventh slot while performing the [[Old Man Glitch]]
[[File:Missingno Y.png|frame|right]]
# If a player does method #3 of the Mew glitch with a Pokémon which has a special stat of 183
MissingNo.'s {{v2|Yellow}} normal form is a dual-type {{t|Normal}} and randomly named glitch type (often containing '9') glitch Pokémon. This form uses the palette of {{p|Pikachu}}, and so appears as yellow and red glitched boxes. They also cause glitches that MissingNo. in Red and Blue do not. If caught, they 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 after battle. These forms do not appear through the [[old man glitch]], as it was removed in Yellow. It is likely that the game will freeze or get stuck when attempting to battle Yellow MissingNo.'s normal form due to an invalid sprite pointer; <tt><b>0x0600</b></tt>. This is also what causes the walking characters effect.


Its final form displays the sprite of the [[Literal ghost|Ghosts]] found in {{g|Tower}} before obtaining the [[Silph Scope]]. In the Japanese versions, this Missingno. was named "Ghost." It appears in only two ways:
* This form appears through the [[Mew glitch]] with a {{stat|Special}} stat of 31, 32, 56, 61, 62, 63, 67, 68, 69, 86, 87, 94, 95, 115, 121, 122, 127, 134, 135, 137, 140, 146, 156, 159, 160, 161, 162, 172, 174, 175 or 181.
* This form can be obtained through the [[Time Capsule exploit]] if the [[trade]]d Pokémon is {{p|Scizor}}, {{p|Shuckle}}, {{p|Heracross}}, {{p|Sneasel}}, {{p|Teddiursa}}, {{p|Ursaring}}, {{p|Slugma}}, {{p|Magcargo}}, {{p|Swinub}}, {{p|Piloswine}}, {{p|Corsola}}, {{p|Remoraid}}, {{p|Octillery}}, {{p|Delibird}}, {{p|Mantine}}, {{p|Skarmory}}, {{p|Houndour}}, {{p|Houndoom}}, {{p|Kingdra}}, {{p|Phanpy}}, {{p|Donphan}}, {{p|Porygon2}}, {{p|Stantler}}, {{p|Smeargle}}, {{p|Tyrogue}}, {{p|Hitmontop}}, {{p|Smoochum}}, {{p|Elekid}}, {{p|Magby}}, {{p|Miltank}}, {{p|Blissey}}, {{p|Raikou}}, {{p|Entei}}, {{p|Suicune}}, {{p|Larvitar}}, or {{p|Ho-Oh}}.
* Encountering this MissingNo. form is '''not''' safe, as it usually causes the game to freeze or get stuck.


# If a lowercase 'y' is found in the player's name in the third, fifth or seventh slot while performing the [[Old Man Glitch]]
===Fossil and ghost MissingNo.===
# If a player does method #3 of the [[Mew glitch]] with a Pokémon which has a special stat of 184
The [[Fossil]] and ghost MissingNo. (otherwise known as 'special MissingNo.') are three unique forms of MissingNo. that share their sprites with the {{p|Kabutops}} Fossil and {{p|Aerodactyl}} Fossil from the [[Pewter Museum of Science]], as well as the {{OBP|ghost|Pokémon Tower}}s of [[Pokémon Tower]]. This is because the game actually uses their index numbers to get their front sprites. These Pokémon have no constant [[base stats]], [[List of Pokémon by experience type|experience types]] or starting [[move]]s; instead they take this data from the last Pokémon in the party other than another special MissingNo. If an enemy {{pkmn|Trainer}} sends out a special MissingNo. the aforementioned data is taken from the previous Pokémon they sent out (the user's Pokémon in battle does not count here).


====Gender differences====
The Fossil and ghost MissingNo. exist in Yellow and have the same sprites as in {{2v2|Red|Blue}}. They also work the same way. Since the sprites are valid, these MissingNo. can be encountered instead of Yellow's normal MissingNo. and will never freeze the game on the opponent's side.
Missingno.'s only appearances were in [[Generation I]] games, where genders were not yet specified. As a result, Missingno. has no known gender.


===Special abilities===
===={{p|Kabutops}} [[Fossil]] form====
Missingno. is notable as being one of the few non-Flying-type Pokémon to learn {{m|Sky Attack}}.
[[File:Spr 1b 141 f.png|thumb]]
MissingNo.'s {{p|Kabutops}} Fossil form uses the sprite of the {{p|Kabutops}} Fossil found in the [[Pewter Museum of Science]]. It is index number 182 (hex:B6).


Missingno.'s appearance in-battle allows what is commonly known as the "[[Rare Candy cheat]]," the {{2v2|Red|Blue}} versions' infamous item duplication bug. It is commonly used to duplicate valuable and hard-to-obtain items, such as the [[Rare Candy]] (hence the name of the cheat). However, the duplication bug can affect any item in the game, not just Rare Candies.  It even affects Key Items, making it nearly impossible to deposit them in the PC.  However, this does allow players to revive a large number of {{p|Aerodactyl}} and {{p|Omanyte}}/{{p|Kabuto}}.
* 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 {{stat|Special}} stat of 182.
* This form can be obtained through the [[Time Capsule exploit]] if the [[trade]]d Pokémon is {{p|Pupitar}}.


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. However, neither of these do any significant damage.
===={{p|Aerodactyl}} [[Fossil]] form====
[[File:Spr 1b 142 f.png|thumb]]
MissingNo.'s {{p|Aerodactyl}} Fossil form uses the sprite of the {{p|Aerodactyl}} Fossil found in the [[Pewter Museum of Science]]. It is index number 183 (hex:B7).


===Behavior===
* 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.
Having appeared in no canon other than the games, and having no discernable [[Pokédex]] information, Missingno. has no known behavior.
* This form appears through the [[Mew glitch]] with a {{stat|Special}} stat of 183.
* This form can be obtained through the [[Time Capsule exploit]] if the [[trade]]d Pokémon is {{p|Tyranitar}}.


===Habitat===
===={{OBP|Ghost|Pokémon Tower}} form====
Due to errors in the programming of the games, Missingno. is found most often on the east coast of [[Cinnabar Island]], though has been known to appear on the eastern coast of the [[Seafoam Islands]], and can be found via the [[Mew Glitch]].
[[File:Ghost I.png|thumb]]
MissingNo.'s Ghost form uses the sprite of the {{OBP|ghost|Pokémon Tower}}s found in [[Pokémon Tower]] if the player does not have the [[Silph Scope]]. It is index number 184 (hex:B8)


===Diet===
In the Japanese versions, this form is not actually a MissingNo. In these versions, rather than being named 'けつばん' (ketsuban) it is named "Ghost" (Japanese: ゴースト). This is unused, because all Pokémon Tower ghosts including {{OBP|Marowak|ghost|the deceased Marowak}} use the hiragana ゆうれい ('[[wikipedia:Yūrei|yuurei]]') instead, which can mean the same thing but may specifically refer to the Japanese interpretation of ghosts in folklore.
{{main|Pokémon food}}
Missingno.'s dietary specifications are unknown.


==Trading Missingno.==
* 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.
Missingno. can be traded into the [[Pokémon Yellow]] version of the game, but cannot be traded into [[Pokémon Gold and Silver]], the sequels to Red, Blue, and Yellow. In Pokémon Yellow, Missingno. levels down to [[level]] 1 and stays there, in essence, permanently. After gaining any experience points, Missingno. reverts to level one, so the only way it can be used in battle at a different level is during a [[link cable|linked]] [[Pokémon battle|battle]].  
* This form appears through the [[Mew glitch]] with a {{stat|Special}} stat of 184.
* This form appears through evolving [[.PkMn|.{{PK}}{{MN}}]]{{sup/1|RB}} or [[Z ゥ]]{{sup/1|Y}} at level 224.
* This form can be obtained through the [[Time Capsule exploit]] if the [[trade]]d Pokémon is {{p|Lugia}}.


When it is traded, Missingno. appears as one of many different [[Pokémon]] from the Gold/Silver perspective, and when the player tries to [[trade]] Missingno. a message appears that says "<i>Your <name> appears abnormal</i>" and the trade automatically cancels. However, there are rare cases of it successfully being traded and turning into to the Pokémon that it was said to be. If it does, and is attempted to be traded back a Generation I game while the players are still in the Time Capsule, it will turn back into a Missingno.
==Glitches caused==
[[File:Halloffameglitches.png|thumb|160px|Examples of corrupted Hall of Fame entries]]
[[File:Missingno glitch walking players.png|thumb|left|160px|Example of multiple walking players on the screen]]
MissingNo.'s appearance in-battle allows the [[Item duplication glitch#Pokédex 000 item duplication glitch|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.


==Why Missingno. appears==
Encountering MissingNo. has been known to interfere with the save game data in various ways, such as adversely affecting the [[Hall of Fame]] data. The Hall of Fame is corrupted because of its proximity to a buffer used to store decompressed sprite data, which is too small to properly hold MissingNo.'s garbage sprite data.
'''Missingno.''' is the [[Glitch]] Pokémon that appears after viewing the Old Man's tutorial in [[Viridian City]] on how to catch Pokémon, then immediately {{m|Fly}}ing to [[Cinnabar Island]] and {{m|Surf}}ing along the right hand side of the island until one is encountered, without visiting any other areas.


Whenever the game "sets up" the planned battle against the Old Man's {{p|Weedle}}, it needs to change the player's character name to "OLD MAN" so that it will display "OLD MAN" instead of the name the player has entered.  
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 [[Inverted sprite|reversed]]. Viewing the [[stats]] screen of a non-glitch Pokémon will remove the effects.


The programmers decided to use the area of data where wild [[Pokémon]] information is as a temporary storage area for the player's name, due to the lack of memory on a [[Game Boy]]. Normally this wouldn't cause any abnormal activity, as the correct data for the wild Pokémon available is written to this area in memory whenever the player travels to an area where it is possible to catch wild Pokémon, such as walking in tall grass or using a fishing rod.
In Pokémon Yellow, capturing MissingNo. will commonly cause multiple player sprites, and sometimes other NPC's, to walk around the screen. If the NPC is aligned to the grid, it is possible to talk to them. Doing so may display text from the area, or may cause glitch text. <!--There should be an article on that, but unfortunately isn't. If one were created, the error codes page could be merged.--> Collision with those NPC's is buggy, but the game does handle it.


Along Cinnabar Island's coast, however, there is no data indicating which wild Pokémon are catchable, and the same is true for both Viridian City and Cinnabar Island itself, at least by movement in long grass. The game uses whatever data was already in the corresponding area of data when determining which wild Pokémon encountered and their levels—now the player's name. Normally this space in memory would hold the data of the last area visited where wild Pokémon were catchable in grass and their level data (this same glitch allows players to exit the [[Kanto Safari Zone|Safari Zone]] and {{m|Fly}} immediately to Cinnabar Island to be able to catch and fight Safari Zone Pokémon in the same way as they would in other areas, as Fuchsia City also has no wild Pokémon data for long grass), however, since in both Viridian City and Cinnabar Island the data is empty for Pokémon obtainable in the grass, the active data is never overwritten, leading to Missingno.'s. availability, among other things.
In Pokémon Yellow, if MissingNo. is captured at a level above 1, it will instantly downlevel to 1 upon gaining any experience, and will stay on level 1 unless given [[Rare Candy]]. After this happens, MissingNo. will have seemingly infinite health, and, when damaged, the third digit of its health would, instead of going down through numbers, scroll through letters, numbers, and glitch symbols, and its HP bar will wrap across the screen.


The name of the player has six hexadecimal values in it. The game needs only three "slots" of wild Pokémon data to store this.  
In Pokémon Yellow, when MissingNo. is encountered, if the game doesn't crash, it will sometimes play a very long cry before the text "A wild MISSINGNO appeared!" is displayed.
{{-}}


The wild Pokémon the player encounters along the coast are determined by the third, fifth, and seventh characters of the player's name, while the levels are determined by the second, fourth, and sixth characters, respectively. By knowing which letters and symbols match which species and levels, through use of certain calculators and charts [http://glitchcity.info/misc/namegen2], it is possible to set the player name at the start of the game so as to find specific Pokémon at specific levels.
==Trading MissingNo.==
MissingNo. can be traded from Red and Blue into {{game|Yellow}}, but cannot be traded forward through the [[Time Capsule]] into {{game2|Gold|Silver|Crystal}}. In Yellow, MissingNo. levels down to level 1 if it gains any experience, and cannot grow any higher due to a glitched experience type. In Yellow, the only way to keep using a MissingNo. at a different level in battle is to use a [[Game Link Cable]] to battle between two games.


==Missingno. in Pokémon Yellow==
In the trade center, MissingNo., due to its [[index number]], appears as many different [[Generation II]] Pokémon from the perspective of {{game2|Gold|Silver|Crystal}}. (The full list of the Generation II Pokémon MissingNo. can appear as is documented on the [[List of Pokémon by index number in 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 {{cat|Generation II Pokémon}} and not allow the player to enter the Time Capsule.-->
[[Image:MissingnoYellow.jpg|thumb|right|The appearance of the Missingno. found in the Yellow version using the [[Mew glitch]] is different from the Red/Blue Missingno. appearance]]
When {{game|Yellow}} was released, the original Missingno. and M glitches were disabled and removed from the game.  


However, some time after Yellow was released, a [[Mew Glitch|new code]] was discovered that allowed the capture of any Pokémon, including Mew and Missingno (see [http://www.trsrockin.com/yellowmn.html] for details). Doing method #3 of the [[Mew glitch]] using a Pokémon with a special stat of 31, 32, 61, 62, 63, 67, 68, 69, or 86 will cause a Yellow version Missingno. to appear. The Yellow version Missingno. is known to be more malicious than the Red/Blue Missingno., and frequently causes the game to freeze when it is found. It is recommended that the game ''not'' be saved after capturing it, because it can corrupt or delete the data. If it is caught, it will cause graphical glitches, such as rendering the player invisible, and causing lots of duplicates of the player to walk all over the screen.
In the [[Nintendo 3DS]] [[Virtual Console]] versions, if the player has MissingNo. in Box 1 when they attempt to transfer it to [[Pokémon Bank]] via [[Poké Transporter]], one of the following error messages will appear. All Pokémon in Box 1 that are recognized as valid by Poké Transporter will be transported, but [[glitch Pokémon]] (such as MissingNo.) will not.
<blockquote>Attention!<br>There is at least one Pokémon in the Box that cannot be sent.
A problem has been detected with one of the Pokémon. Sorry. The problematic Pokémon cannot be sent.
Any Pokémon that could not be transported have been removed from the Transport Box.</blockquote>


Another way of capturing a Yellow version Missingno. is to trade a Missingno. from the Red/Blue versions. Until the discovery of the [[Mew glitch]], the only way to obtain a Yellow version Missingno. was to trade a Missingno. from the Red/Blue versions.
==In [[Pokémon Stadium]]==
[[File:Missingno Substitute doll screen.png|thumb|right|250px|MissingNo. as a [[Substitute (doll)|substitute doll]] in Pokémon Stadium]]
When viewed in [[Pokémon Stadium]], MissingNo. will appear as a [[Substitute (doll)|substitute doll]] (as will various other glitch Pokémon), while in [[Pokémon Stadium 2]], MissingNo. (and other glitch Pokémon) will show up as a {{p|Ditto}} with {{m|Transform}}. If the game is saved via Stadium 2, it will then become a Ditto permanently.
{{clear}}
 
==MissingNo. as deleted Pokémon==
The name "MissingNo." is used for the invalid Pokémon with index numbers in between valid Pokémon and is a shortened form of "missing number", derived from its Japanese name, けつばん (Ketsuban). The fact that {{p|Rhydon}}, the Pokémon with index number <tt><b>01</b></tt> was the first Pokémon ever made<ref>[http://www.nintendo.co.jp/nom/0007/gfreak/page02.html 開発スタッフインタビュー/キャラクターが決まるまで - Nintendo of Japan]</ref><ref>[http://www.glitterberri.com/pokemon-red-blue/game-freak-staff-interview/creating-the-pokemon/ GlitterBerri's Game Translations » Creating the Pokémon]</ref> led to speculation that the [[List of Pokémon by index number in Generation I|index numbers of Pokémon in Generation I]] represent the order that they were programmed into the game, with MissingNo. being deleted entries.
 
Supporting this theory was the fact that of the 39 MissingNo., nine of them have unique cries that do not consist of all <tt><b>00</b></tt> values.<ref>[https://iimarckus.org/i/missing-number/ Missing Number - IIMarck.us]</ref> These cries are located in a table in between real Pokémon cries, suggesting that they were not garbage data (unrelated data interpreted in the wrong way, as is the case with most of MissingNo.'s properties).
 
The cry values are as follows:
 
{| {| style="background: #{{unknown color light}}; {{roundy|1em}}; border: 5px solid #{{unknown color}}; margin:auto"
|-

==Missingno. in Pokémon Stadium==
([https://www.youtube.com/watch?v=ZYEeLYSM5P0 Video of the cries])
When a Missingno. or other glitch Pokémon is viewed in {{Eng|Pokémon Stadium}}, it will appear as a baby {{p|Rhydon}} (the image used in the substitute attack). When viewed in {{g|Stadium 2}}, Missingno. will show up as a {{p|Ditto}}, and if the game is then saved from Stadium 2, the Pokémon will be a Ditto permanently.


==Nintendo on Missingno.==
These theories were finally confirmed in 2020, with {{wp|2020-2021_Nintendo_data_leak|the Nintendo data leak of that year}}. Among the game material leaked was the source code for the [[Pokémon Blue Version (Japanese)|Japanese version of Pokémon Blue]], which contained many internal development assets, such as map sources, moveset lists, cry data, and the back sprites for every Pokémon in the game in Generation I order, including previously-unseen sprites occupying the same index numbers populated by MissingNo. in the released games.<ref>[https://tcrf.net/Pok%C3%A9mon_Red_and_Blue/MissingNo.#MissingNo._List The Cutting Room Floor - Pokémon Red and Blue/Missingno.]</ref> Some of these sprites match the design and index number of Pokémon previously only shown on [[Satoshi Tajiri]]'s [[Satoshi Tajiri: The Man Who Created Pokémon|biographical manga]], while most of the others correspond to Pokémon that had never been seen before.
Nintendo has an official description of Missingno. listed in their Customer Service troubleshooting section<ref name="NintendoTroubleshooting">http://www.nintendo.com/consumer/systems/gameboy/trouble_specificgame.jsp</ref>:


<blockquote>"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 Flight Safari Zone Pokémon trick [or Viridian Old Man trick]. To fix the scrambled graphics, try releasing the MissingNO Pokémon."</blockquote>
==Official Nintendo statement==
[[Nintendo]] has an official description of MissingNo. listed in their Customer Service troubleshooting section:
 
<blockquote><p>"MissingNO is a programming quirk, and not a real part of the game. When you get this, your game can perform strangely, and the [[Inverted sprite|graphics will often become scrambled]]. The MissingNO Pokémon is most often found after you perform the [[Fight Safari Zone Pokémon trick]].</p>
 
<p>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."<ref name="NintendoTroubleshooting">[https://web.archive.org/web/20221001001612/https://www.nintendo.com/consumer/systems/gameboy/trouble_specificgame.jsp Nintendo - Customer Service]</ref></p></blockquote>
 
Nintendo's statement is incorrect on the method for fixing graphical issues; releasing MissingNo. does not fix the graphics and the player certainly does not need to erase their game to perform any fixes. The correct way to fix the graphics is to simply view the Pokédex data or stat page of any non-glitch Pokémon (or any [[Glitch Pokémon family|hybrid glitch Pokémon]]). The statement may have been deliberately worded to discourage players from performing the [[item duplication glitch]].
 
The title of the statement also refers to MissingNo. as "Pokémon 000" in reference to its Pokédex number.

===Pokédex entries===
===Pokédex entry===
If Missingno. is caught, it will not appear in the Pokédex (unless caught via the Mew Glitch BEFORE passing through [[Rock Tunnel]] or getting it as a starter by using a cheat device, and even then, the entry is blank). This is because the bit of data that tells the game that Missingno. is captured is the same as the data for battling a Cubone, and there are unavoidable trainers in Rock Tunnel who use Cubone. Because of this, there is no official Pokédex description for Missingno. If Missingno.'s Pokédex data is viewed, it will consist of a very long string of glitchy sounds, much like [[.4]] or [[H POKé|h Poké]]'s entries. However, unlike their entries, Missingno.'s does not lock up the game.

==Trivia==
==Trivia==
*Missingno. has the highest {{stat|Attack}} [[base stat]] of all Pokémon in [[Pokémon Red and Blue]] and the ninth highest out of '''''all''''' Pokémon. Likewise, it has the lowest {{stat|Defense}} base stat of any Pokémon, and the third lowest {{stat|Speed}} base stat, only losing to {{p|Shuckle}} and {{p|Munchlax}} whom each have a base Speed of 5 each.
[[File:MissingNo artwork.jpg|thumb|220px|The now-deleted fan art by TOKIYA]]
*Missingno. is the heaviest of all Pokémon, its weight surpassing even {{p|Groudon}}.
* The {{game|Yellow}} normal form MissingNo. have 0 base speed. This ties with various [[Generation I]] glitch Pokémon for the lowest base Speed stat.
*Despite it being almost half of [['M]]'s height, it is more than twice its weight.
* In the Spanish versions of Pokémon Red and Blue, viewing the stat screen of any Pokémon in the player's party changes MissingNo.'s sprite.<ref>[https://www.youtube.com/watch?v=4T1j_BV7NMM Change the sprite of MissingNo with view the stats of any Pokémon in your team]</ref>
*Missingno.'s cry is the game's equivalent of a "blank" cry: a Nidoran's voice with a pitch of 0 and no echo.
* In its normal form, MissingNo. has the same learnset as [['M (00)]], except that 'M (00) cannot learn {{m|Substitute}} via [[TM50]] and MissingNo. cannot learn {{m|Pound}}.
*Before the truth about how Missingno. exists was known, many fans speculated that it was a removed [[legendary Pokémon]] (Given its extremely low catch rate, one can see the reasoning behind this).
* Normal form MissingNo.'s stats in {{v2|Red and Blue|s}} are actually determined by the [[Party|parties]] of several {{tc|Biker}}s, read as base stats.<ref name="TheSmogIssue27">[http://www.smogon.com/smog/issue27/glitch Smogon - The Smog Issue #27]</ref>
*In its normal form, it shares the exact same movepool as 'M, with two exceptions; It doesn't learn {{m|Pound}}, and can learn the TM for {{m|Substitute}}.
* MissingNo. is the only [[glitch Pokémon]] in [[Generation I]] whose English name is entirely composed of typographical characters. Although other glitch Pokémon such as [[Trainer (glitch Pokémon)|Trainer]] and [[C (uppercase)|C]] may appear to be entirely composed of typographical characters, they contain illegible characters which change depending on the current tileset loaded into memory.
*If Missingno.'s [[Pokédex]] data is somehow accessed, it will consist of a very long string of glitched sounds. Unlike [[.4]] or [[h POKé]]'s Pokédex data, however, it will not lock up the game. Also when it's accessed when Missingno is first caught, Missingno will turn into a Rhydon.
* In the [[Generation IV]] games, there is a sprite ([[File:GenIVKetsuban.png]]) that contains text that reads {{ruby|欠番|けつばん}}, MissingNo.'s Japanese name in {{wp|kanji}}. However, unlike the Generation I placeholder text "MissingNo.", it exists only to substitute blank tile data, not blank species data. This means that the game will display this if a sprite is referenced that does not exist or cannot be accessed.
*A rumor claims that the player must have five or less [[Pokémon]] with him or her if he or she actually tries to catch Missingno., otherwise, his or her game may malfunction when he or she tries to withdraw it from [[Bill's PC]]. (If, of course, a player has six [[Pokémon]] at the time Missingno. is caught, Missingno. will be sent to Bill's PC, just like any other Pokémon.) This rumor will only hold true, however, if the Pokémon in question is level 0 (It is impossible to encounter a Missingno. at level 0). Therefore, it is possible to extract Missingno. from Bill's PC without game malfunction.
* MissingNo. is referred to as "Pokémon 000" on [[Nintendo]]'s consumer support website, referencing its Pokédex number.
*As mentioned before, if the Elite Four is defeated and the Hall of Fame option appears in the PC, seeing Missingno. will cause very distorted characters, glitched names and completely different Pokémon to show up instead of your Pokémon who have beaten the Elite Four. The Hall of Fame is the only extremely noticeable change after seeing Missingno.
** The only Pokémon to legitimately have the number 000 in any Pokédex listing is {{p|Victini}}, whose number in the [[Unova Pokédex]] is 000.
*Though Missingno. cannot usually be traded into [[Generation II]], it will appear to be a G/S/C Pokémon such as {{p|Remoraid}} or {{p|Stantler}} on the trade screen for Gold/Silver/Crystal, depending on its [[index number]]. If succesfully traded to a Generation II game, it will turn into the Pokémon that the Generation II game called it.
* In August 2016, TCG artist [[TOKIYA]] posted (now-deleted) fan art of MissingNo.'s Ghost form, Aerodactyl and Kabutops fossil appearances, and default sprite in [[Pokémon Red and Green]] on her Twitter;<ref name="TOKIYAMissingNoArt">[https://twitter.com/TOKIYA/status/760264929307799552 Art by TOKIYA on Twitter] [https://web.archive.org/web/20170403110029if_/https://twitter.com/TOKIYA/status/760264929307799552 (Archive)]</ref> MissingNo. is therefore the only known glitch Pokémon to have an intentional depiction by a franchise artist.
*Rumors are still plentiful that capturing Missingno. can cause permanant damage to your game, possibly even erasing the save files, when in fact, the Hall of Fame glitching is the only permanent side effect, rendering Missingno. usually safe to capture and train.
* MissingNo. was alluded to throughout an April 1, 2024 episode of [[Beyond the Pokédex]] about {{p|Magmar}}.<ref name="BeyondThePokedex">[https://www.youtube.com/watch?v=LN8P5lCPRsU Magmar | Beyond the Pokédex - Entry #126] - YouTube</ref>
*As Missingno. is caught at a [[level]] higher than 100, it is possible to increase its level even higher by using Rare Candies. The maximum level it reaches is 255, and if another Rare Candy is used, it will revert to level 1.
** After Maple captures an unseen Pokémon in [[Cinnabar Island]] at the beginning of the episode, the episode is then continuously interrupted with glitchy visuals, possibly referencing the [[Inverted sprites|scrambled graphics]] that can occur after encountering MissingNo. as well as other glitch Pokémon. Additionally, these interruptions notably occur after either of the hosts mention the phrase "missing number" and the move {{m|Water Gun}}, a move in MissingNo.'s starting learnset.
*When leveling up a Missingno. of a level over 100 via Rare Candies; if the Missingno. gains battle EXP and levels up, it will revert permanently to Level 100.
** Spruce asks Maple if she happened to be "{{m|Surf|surfing}} up the east coast of Cinnabar Island" when she captured the Pokémon, likely referencing the [[old man glitch]], which is the most well-known method of encountering MissingNo.
====Name origin====
** Maple suggests "turning [the camera] off and on again" and "blowing air into the bottom of the cartridge" to fix the interruptions. After neither method works, both hosts elect to "erase the whole file and start from the beginning", restarting the episode after the file deletion screen from Red and Blue is shown. This aligns with Nintendo's official statement on MissingNo., where erasing the save file is incorrectly presented as the only solution if releasing it does not correct the scrambled graphics.
Missingno.'s English and Japanese names are both derived from "Missing Number".

MissingNo. (Japanese: けつばん Ketsuban, lit. "missing number"), as it is displayed in-game due to the ten-character limit in Western Generation I games, is a dual-type Bird/Normal glitch Pokémon in Pokémon Red and Blue, and a dual-type Normal/randomly named glitch type (which often has '9' in it) glitch Pokémon in Pokémon Yellow. It is arguably the best known glitch Pokémon, closely followed by 'M (00), and it is the easiest glitch Pokémon to find in the localizations. It has five distinct forms, but the most frequent forms (the Red/Blue and Yellow normal forms) share 36 index numbers each.

In later generations, other glitch Pokémon are sometimes referred to as "a MissingNo.", such as ??????????, ?, and -----. Despite this, the name "MissingNo." is a misnomer in this case; they have little relation to the one found in Pokémon Red and Blue or Yellow.

MissingNo.'s cry is generally the game's equivalent of a "blank" cry: a Nidoran♂ (base 00)'s cry with a pitch of 0 and no echo. This is because the cries of these Pokémon are undefined in the data structure. A few MissingNo. have different cries (specifically 0x43, 0x45, 0x4F, 0x51, 0x5E, 0x5F, 0x7F, and 0xB5). The fact that these cries are valid and not garbage data (i.e. unrelated data read in the wrong way, as is the case with most of MissingNo.'s properties) supports the view that MissingNo. may have originally been a Pokémon that was deleted from the games. (See this section for further details).

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 rule is in Red and Green, where MissingNo. can be "registered" in the Pokédex if the player enables the 'seen' flag for #152 through select glitches and memory corruption. If MissingNo.'s Pokédex data is viewed, Rhydon's cry will be heard, followed by MissingNo.'s (blank) entry and a series of glitchy sounds.

No MissingNo. can evolve or learn any moves through leveling up.

If the RB MissingNo. is traded to Generation II, it will hold a Carbos.

Forms

Red and Blue normal form

Missingno RB.png

MissingNo.'s Red and Blue normal form is a dual-type Bird/Normal glitch Pokémon. It 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.

Yellow normal form

Missingno Y.png

MissingNo.'s Yellow normal form is a dual-type Normal and randomly named glitch type (often containing '9') glitch Pokémon. This form uses the palette of Pikachu, and so appears as yellow and red glitched boxes. They also cause glitches that MissingNo. in Red and Blue do not. If caught, they 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 after battle. These forms do not appear through the old man glitch, as it was removed in Yellow. It is likely that the game will freeze or get stuck when attempting to battle Yellow MissingNo.'s normal form due to an invalid sprite pointer; 0x0600. This is also what causes the walking characters effect.

Fossil and ghost MissingNo.

The Fossil and ghost MissingNo. (otherwise known as 'special MissingNo.') are three unique forms of MissingNo. that share their sprites with the Kabutops Fossil and Aerodactyl Fossil from the Pewter Museum of Science, as well as the ghosts of Pokémon Tower. This is because the game actually uses their index numbers to get their front sprites. These Pokémon have no constant base stats, experience types or starting moves; instead they take this data from the last Pokémon in the party other than another special MissingNo. If an enemy Trainer sends out a special MissingNo. the aforementioned data is taken from the previous Pokémon they sent out (the user's Pokémon in battle does not count here).

The Fossil and ghost MissingNo. exist in Yellow and have the same sprites as in Red and Blue. They also work the same way. Since the sprites are valid, these MissingNo. can be encountered instead of Yellow's normal MissingNo. and will never freeze the game on the opponent's side.

Kabutops Fossil form

Spr 1b 141 f.png

MissingNo.'s Kabutops Fossil form uses the sprite of the Kabutops Fossil found in the Pewter Museum of Science. It is index number 182 (hex:B6).

Aerodactyl Fossil form

Spr 1b 142 f.png

MissingNo.'s Aerodactyl Fossil form uses the sprite of the Aerodactyl Fossil found in the Pewter Museum of Science. It is index number 183 (hex:B7).

Ghost form

Ghost I.png

MissingNo.'s Ghost form uses the sprite of the ghosts found in Pokémon Tower if the player does not have the Silph Scope. It is index number 184 (hex:B8)

In the Japanese versions, this form is not actually a MissingNo. In these versions, rather than being named 'けつばん' (ketsuban) it is named "Ghost" (Japanese: ゴースト). This is unused, because all Pokémon Tower ghosts including the deceased Marowak use the hiragana ゆうれい ('yuurei') instead, which can mean the same thing but may specifically refer to the Japanese interpretation of ghosts in folklore.

Glitches caused

Examples of corrupted Hall of Fame entries
Example of multiple walking players on the screen

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 data. The Hall of Fame is corrupted because of its proximity to a buffer used to store decompressed sprite data, which is too small to properly hold MissingNo.'s garbage sprite data.

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.

In Pokémon Yellow, capturing MissingNo. will commonly cause multiple player sprites, and sometimes other NPC's, to walk around the screen. If the NPC is aligned to the grid, it is possible to talk to them. Doing so may display text from the area, or may cause glitch text. Collision with those NPC's is buggy, but the game does handle it.

In Pokémon Yellow, if MissingNo. is captured at a level above 1, it will instantly downlevel to 1 upon gaining any experience, and will stay on level 1 unless given Rare Candy. After this happens, MissingNo. will have seemingly infinite health, and, when damaged, the third digit of its health would, instead of going down through numbers, scroll through letters, numbers, and glitch symbols, and its HP bar will wrap across the screen.

In Pokémon Yellow, when MissingNo. is encountered, if the game doesn't crash, it will sometimes play a very long cry before the text "A wild MISSINGNO appeared!" is displayed.

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 due to a glitched experience type. In Yellow, the only way to keep using a MissingNo. at a different level in battle is to use a Game 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. (The full list of the Generation II Pokémon MissingNo. can appear as is documented on the List of Pokémon by index number in 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.

In the Nintendo 3DS Virtual Console versions, if the player has MissingNo. in Box 1 when they attempt to transfer it to Pokémon Bank via Poké Transporter, one of the following error messages will appear. All Pokémon in Box 1 that are recognized as valid by Poké Transporter will be transported, but glitch Pokémon (such as MissingNo.) will not.

Attention!
There is at least one Pokémon in the Box that cannot be sent.

A problem has been detected with one of the Pokémon. Sorry. The problematic Pokémon cannot be sent.

Any Pokémon that could not be transported have been removed from the Transport Box.

In Pokémon Stadium

MissingNo. as a substitute doll in Pokémon Stadium

When viewed in Pokémon Stadium, MissingNo. will appear as a substitute doll (as will various other glitch Pokémon), while in Pokémon Stadium 2, MissingNo. (and other glitch Pokémon) will show up as a Ditto with Transform. If the game is saved via Stadium 2, it will then become a Ditto permanently.

MissingNo. as deleted Pokémon

The name "MissingNo." is used for the invalid Pokémon with index numbers in between valid Pokémon and is a shortened form of "missing number", derived from its Japanese name, けつばん (Ketsuban). The fact that Rhydon, the Pokémon with index number 01 was the first Pokémon ever made[1][2] led to speculation that the index numbers of Pokémon in Generation I represent the order that they were programmed into the game, with MissingNo. being deleted entries.

Supporting this theory was the fact that of the 39 MissingNo., nine of them have unique cries that do not consist of all 00 values.[3] These cries are located in a table in between real Pokémon cries, suggesting that they were not garbage data (unrelated data interpreted in the wrong way, as is the case with most of MissingNo.'s properties).

The cry values are as follows:

Hex Dec Base cry Pitch Length
0x43 67 0 128 16
0x45 69 29 244 64
0x4F 79 34 255 64
0x51 81 14 224 96
0x5E 94 15 64 192
0x5F 95 15 32 192
0x7F 127 17 32 16
0x89 137 15 64 128
0xB5 181 29 0 128

(Video of the cries)

These theories were finally confirmed in 2020, with the Nintendo data leak of that year. Among the game material leaked was the source code for the Japanese version of Pokémon Blue, which contained many internal development assets, such as map sources, moveset lists, cry data, and the back sprites for every Pokémon in the game in Generation I order, including previously-unseen sprites occupying the same index numbers populated by MissingNo. in the released games.[4] Some of these sprites match the design and index number of Pokémon previously only shown on Satoshi Tajiri's biographical manga, while most of the others correspond to Pokémon that had never been seen before.

Official Nintendo statement

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."[5]

Nintendo's statement is incorrect on the method for fixing graphical issues; releasing MissingNo. does not fix the graphics and the player certainly does not need to erase their game to perform any fixes. The correct way to fix the graphics is to simply view the Pokédex data or stat page of any non-glitch Pokémon (or any hybrid glitch Pokémon). The statement may have been deliberately worded to discourage players from performing the item duplication glitch.

The title of the statement also refers to MissingNo. as "Pokémon 000" in reference to its Pokédex number.

Trivia

The now-deleted fan art by TOKIYA
  • The Pokémon Yellow normal form MissingNo. have 0 base speed. This ties with various Generation I glitch Pokémon for the lowest base Speed stat.
  • In the Spanish versions of Pokémon Red and Blue, viewing the stat screen of any Pokémon in the player's party changes MissingNo.'s sprite.[6]
  • In its normal form, MissingNo. has the same learnset as 'M (00), except that 'M (00) cannot learn Substitute via TM50 and MissingNo. cannot learn Pound.
  • Normal form MissingNo.'s stats in Red and Blue are actually determined by the parties of several Bikers, read as base stats.[7]
  • MissingNo. is the only glitch Pokémon in Generation I whose English name is entirely composed of typographical characters. Although other glitch Pokémon such as Trainer and C may appear to be entirely composed of typographical characters, they contain illegible characters which change depending on the current tileset loaded into memory.
  • In the Generation IV games, there is a sprite (GenIVKetsuban.png) that contains text that reads 欠番(けつばん), MissingNo.'s Japanese name in kanji. However, unlike the Generation I placeholder text "MissingNo.", it exists only to substitute blank tile data, not blank species data. This means that the game will display this if a sprite is referenced that does not exist or cannot be accessed.
  • MissingNo. is referred to as "Pokémon 000" on Nintendo's consumer support website, referencing its Pokédex number.
    • The only Pokémon to legitimately have the number 000 in any Pokédex listing is Victini, whose number in the Unova Pokédex is 000.
  • In August 2016, TCG artist TOKIYA posted (now-deleted) fan art of MissingNo.'s Ghost form, Aerodactyl and Kabutops fossil appearances, and default sprite in Pokémon Red and Green on her Twitter;[8] MissingNo. is therefore the only known glitch Pokémon to have an intentional depiction by a franchise artist.
  • MissingNo. was alluded to throughout an April 1, 2024 episode of Beyond the Pokédex about Magmar.[9]
    • After Maple captures an unseen Pokémon in Cinnabar Island at the beginning of the episode, the episode is then continuously interrupted with glitchy visuals, possibly referencing the scrambled graphics that can occur after encountering MissingNo. as well as other glitch Pokémon. Additionally, these interruptions notably occur after either of the hosts mention the phrase "missing number" and the move Water Gun, a move in MissingNo.'s starting learnset.
    • Spruce asks Maple if she happened to be "surfing up the east coast of Cinnabar Island" when she captured the Pokémon, likely referencing the old man glitch, which is the most well-known method of encountering MissingNo.
    • Maple suggests "turning [the camera] off and on again" and "blowing air into the bottom of the cartridge" to fix the interruptions. After neither method works, both hosts elect to "erase the whole file and start from the beginning", restarting the episode after the file deletion screen from Red and Blue is shown. This aligns with Nintendo's official statement on MissingNo., where erasing the save file is incorrectly presented as the only solution if releasing it does not correct the scrambled graphics.

Name origin

MissingNo.'s English and Japanese names are both derived from "missing number".
