(How the hhhh did you find this) Imago Minus is a trying artist's avatar, a nobody pretty much anywhere. They try to find a way to show off their creativity, halted primarily, but not solely, by their lack of artistic skills and motivation.

The character itself is the result of the artist's absurd power fantasies. They are an entity resulting from the fusion of all vengeful souls once stuck in the void via a limbo of eternal death, having returned from the void through sheer determination. Their very existence breaks the laws of reality, and they would never die until they have gotten enough revenge and redemption to be thoroughly satisfied, and they would return whenever too many new vengeful souls arrive in the void. Like i said, power fantasy.

Just in case it matters, their abilities, while incomprehensibly vast, primarily revolve around the concept of paranormal activities and physics-breaking phenomena in the real world such as ghosts, curses, the aetherial planes, manifestation and presence. Because their soul is naturally far greater, any such occurrences are amplified into being actual superpowers.

(the designs change constantly, though not much is really shown. The current image happens to be the most detailed one so far)
