Like adult acne and high heeled crocs, MissingNo. should not exist. Perhaps one of the most infamous Pokémon — and perhaps not a Pokémon at all — MissingNo. was found lurking around the Cinnabar Island coast to my absolute unparalleled horror. Sure, encountering MissingNo. in the Blue or Red version was an essential part of the Old Man Glitch, and those rare candies, Master Balls and nuggets weren’t going to duplicate themselves. But MissingNo. and his graphics-distorting powers definitely gave us all the wiggins as little kids, and his legend looms large today. Even still, the most unsettling part of the legend goes back to how this creature, this “Misssing Number,” should not exist.
However, MissingNo. does exist, and though we’ve yet to decrypt that existence in full, here’s a little bit of data on the iconic bundle of bytes.
