Negative is a very pathetic, insane, and evil demon, but always very apologetic and very whiny. He is the 0th's alter. In the past, Negative possessed 0th which makes 0th looks like the demon, but in reality, Negative is the demon. He is usually scared of people who aren't familiar to him, and even worse, crowds. He doesn't remember names very well, even himself, except for 0th. He only remembers faces that 0th cares about.
