A ghost from an old game with some unreliable coding, this spirit can shift between a few forms at will, some of which include a black ghost with a malevolent smile, one of 2 different fossils, and a backwards L of data. It can even make some of its body one form while the rest is another form, making it an unpredictable and chaotic creature.

Its hobbies include duplicating items, vandalizing various museums and halls of fame, and causing distortions and corruptions in the environment with its very presence. While the first hobby does make it useful, the second reason makes it very hard to control, while the last reason is why the other players and the staff have been advised to keep a safe distance from Missingno.

However, these corrupted bits and bytes of data can be used as a deadly, if unreliable stabbing weapon, especially if it transform some of itself into what appear to be the scythe-like arms of a Kabutops. Unfortunately, it only seems to do this when it wants to and not on demand. It is also hard to find out why it doesn't want to do it, mainly because its speech is all garbled and impossible to understand.

Either way, the management has hopes that this abomination of programming can at least do some damage to whoever the spooks go up against.
