|This article is a summary page for different variations of a glitches, etc. when talked about as a whole.|
There have been so-called glitches that are merely myths, though they are often fallen for. Common examples are rumors of certain glitches deleting save files and also "secret" Pokémon (commonly called Pokégods).
MissingNo. erasing save files
A glitch myth is that if the player captures a MissingNo. or 'M, his or her save file will be erased. While glitchy occurrences happen such as messed up graphics and messed up Hall of Fame data, they can not cause more significant damage to a save file such as erasing it (messed up graphics can be fixed by viewing the stats of a non-glitch Pokémon).
PokéGod rumors are rumors of "secret" Pokémon, often in the Red, Blue, and Yellow versions of Pokémon. Common rumors include talking to Professor Oak a number of times earning the player a "PokéGod". Also, fake cheats involving hidden non-glitched maps, HMs above HM05, and happenings unfitting to the Pokémon series (e.g. Professor Oak giving the player a slap in the face) usually fall into this category, as they have no truth to them.
Receiving Mew without means of a glitch
The most common rumors involve using Strength on the S.S. Anne Ship Truck to 'find Mew behind the truck', or talking to the man that gives the player a diploma after having all 150 Pokémon. Some have said this only worked in the Japanese versions of the games. Nevertheless, it is still false.
The grass to the west of Route 1
For years gamers have wondered what lies in that seemingly endless expanse of grass to the right and left of Route 1 that is impossible to reach. Some people think that the player can find Mew or glitch Pokémon there. Others think there's a secret area beyond the grass. In reality, the game freezes when the player enters that grass, as there is actually nothing there. The game freezes when the player goes beyond the boundaries in Glitch City, and it freezes for the same reason when entering the grass past the fence in Route 1.
The "Celebi Glitch"
The so-called Celebi Glitch is a glitch myth saying that Celebi can be found in the grass of Route 123 in the Ruby and Sapphire versions of Pokémon. Reports have also existed of it appearing elsewhere. There is supposedly a very little chance of it appearing, such as a "1 in 1,000,000,000,000,000" chance. Glitch Pokémon have also been said to appear like this. Though reports have existed of Celebi being found and captured on Route 123 or somewhere else, there is little chance that there is anything in the game's code that says that it can happen. This glitch myth is not to be confused with the actual glitch to obtain Celebi, the Celebi Trick.
