Other sprites, including those with a dimension width/height value of 0 can freeze the game, but certain glitch Pokémon including Yellow MissingNo., 4 4 (hex:BF) and 4(h4? (hex:ED) can corrupt the current battle (an effect known as a glitch battle not to be confused with a glitch encounter system) in ways such as corrupting what is on the screen or causing glitch music.
