MissingNo.

'''MissingNo. '''is a character in Stealing the Diamond, who only appears in the Goodball fail.

When the Goodball option is chosen, a Pokémon minigame begins in which the nightguards choose Joe to fight, and Henry uses the ball to summon a MissingNo, the glitch Pokemon. This causes the game to glitch and many errors appear on the screen, followed by a blue screen of death, which results in the destruction of the surrounding. This results in a fail.
