#19 The Cubist
Arthur House was an art lover. A HUGE art lover, especially of cubism. Arthur spent a lot of time in the Megalo City Modern Art museum studying the works of Picasso, Braque, Duchamp and others.
After days, months and years of analyzing the cubist masterpieces, Arthur finally wrapped his mind around cubism, learning to see the four-dimensional reality implied by the two-dimensional paintings. As a side effect, Arthur actually began to exist in the fourth-dimension, broken down into simple shapes and able to exist simultaneously in multiple places at once.
Traumatized by having his perceptions suddenly opened, Arthur went insane, becoming a threat and a menace.
