They were a normal Stygian once. It could almost remember those days. But something happened, something broke. Around the time of the tournament with Treatropolis, they thought. Something that felt like a needle in the branch that fed them. Something changed.

The stygian's nature changed.

It forgot its name. Its body split, exposing its darkened Aether. Aether that glitched.

MissingNo isn't malicious. They do not try to inflict the damage their existence causes... but within their own nightmare reality breaks. And it's drawn to others now. Particularly to Divers.

Missingno is personable and gregarious, though often mean. It is prone to pulling pranks and trying to startle guests.

It rarely leaves its own nightmare, as they worry about if the glitches will Extend.
