10 Amazing Glitches That Made Video Games More Fun

10. Missingno - Pokemon Red & Blue

Let's start with the nightmare fuel of many kids growing up in the 90s: Missingno.

Missingno is a mysterious glitched Pokémon from the original Red and Blue games, which became the topic of numerous urban legends across the internet, simply because everything surrounding it just screamed eerie.

Its name literally refers to the fact that the glitchy pokemon is a missing number in the pokedex (it's listed as "000"). As if that wasn't creepy enough, its type (Bird) didn't exist in the original releases of Pokemon Red and Blue, and its appearance is a distorted mass of pixels.

Missingno can be caught on the east coast of Cinnabar Island. However, even just encountering it can cause your game to experience all kinds of issues. The Pokemon will temporarily mess up the game's graphics, break your Hall of Fame, and it can even erase your save data!

On the other hand, Missingno can be used to give yourself an unfair advantage, as it can duplicate items in your inventory, including the one-of-a-kind Master Ball.

Missingno adds some more fun (and fear) to Pokemon. Capturing it makes for an interesting challenge and a fun way to mess with your savefile after beating the game.
