MissingNo.
Pokémon species
MissingNo. ( ; Japanese: けつばん, Hepburn: Ketsuban) is a glitch and an unofficial Pokémon species found in the video games Pokémon Red and Blue. Due to the programming of certain in-game events, players can encounter MissingNo. via a glitch. Encountering MissingNo. causes graphical anomalies and changes gameplay by increasing the number of items in the sixth entry of the player's inventory by 128. This beneficial effect resulted in the glitch's coverage by strategy guides and game magazines, while game publisher Nintendo warned that encountering the glitch may corrupt players' game data.
IGN noted MissingNo.'s appearance in Pokémon Red and Blue was one of the most famous video game glitches and commented on its role in increasing the series' popularity. Fans have attempted to rationalize and incorporate MissingNo. as part of the games' canon as an actual in-game character, and sociologists have studied its impact on both players and gaming culture as a whole.

Why this record matters
“MissingNo.” is worth following because a concise public description often conceals a longer documentary argument. Here, MissingNo, Pokémon and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q1070682. None of the 1 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
