The Abstract

The Abstract is an unknowable and incredibly powerful, mischievous being with dominion over the mind. It goes by many names including Triangulum, the Holy Isosceles, the Master of the Mind, and the All-Seeing Eye of Mischief. Reality is a game to this being from a higher plane.

He cannot pass through Dreamcatchers to affect minds and turquoise blocks his powers from being used on them as well.

The Abstract was trapped inside of the body of Billy Cipher in 1911, fusing with him.
