Parallax

An ancient horror, Parallax, one of the seven emotional entities, is comprised of pure fear that can possess other beings. It is known to ravage planets and strike terror into the hearts of even the Guardians of the Universe.

Parallax is the living embodiment of fear, a demonic parasitic entity which would travel from world to world, causing entire societies to destroy themselves out of fear and paranoia. Parallax is one of the seven Emotional Embodiments representing the individual aspects of the Emotional Spectrum and came into existence when the first insect of Earth emitted fear among its prey.
