There have been many theories about Missingno. Some say it was supposed to be the fourth legendary bird (it sometimes has the cry of Zapdos, and 2 Water Guns and 2 Sky Attacks), so it was probably a Water/Flying type. Also, Missingno. has been the deevoulution of Kangaskhan, the evoulution of Rhydon, and the missing link (i think) between Marowak and Kangaskhan.

MissingNo. (けつばん Ketsuban?), or MissingNO,1is a Pokémon species found in the video games Pokémon Red and Blue. Standing for “Missing Number”, MissingNo. Pokémon are used as error handlers by game developer Game Freak; they appear when the game attempts to access data for a nonexistent Pokémon species. Due to the programming of three in-game events, players can encounter MissingNo. via a glitch. The species was first documented by Nintendo in the May 1999 issue of Nintendo Power.
