CHAOS comes from a broken plane full of uncertainty and emptiness. He claims to be an ancient demon that existed before the birth of the universe. Although the validity of this statement is debatable, his powerful chaotic power and his cruel ambitions are not to be questioned.
The double-edged axe that CHAOS wields can knock any enemy into the void of Chaos, and his extremely violent nature allows him to go berserk and summon savage power at the most critical moments. After receiving the Observer's call, CHAOS extended his ambitious tentacles to Earth.
No one knows where CHAOS came from, but what is known is the being now known as CHAOS once stayed in the Broken Plane for so long it became distorted. CHAOS's tyrannical army, the Chaos Legion, travel to different universes to invade and spread chaos, destroying and assimilating those universes one by one to become part of the Broken Plane.
For CHAOS, disorder is the state the universe should maintain, and all laws and matter should return that state of nothingness and disorder. But when the Chaos Legion came to the material universe, the powerful Universal Guard repeatedly beat the Chaos Legion back to the Broken Plane. So CHAOS turned its attention to the powerful device known as the Vizor of Reality, intending to use it to create a reality that is purely chaotic. And that led the being known as CHAOS to the Quantaar contest...
