Meet Unpredictable. A tiny fragment of Impossible and a traitor. When a war broke out trying to save the humans. Unpredictable decided to change sides which made Impossible furious and he banished him from his dimension never to return.
As a punishment Unpredictable transformed into a dark smokey shroud aka the embodiment of pure evil. He now resides outside the omniverse. His dimension is infinitely large and dark with no light.
