History
The Strange Universe is a dimension dominated by Strange Matter of greater molecular density. This dimension converges with the main universe in some points including a closet of an apartment in New York City and the other in Dr. Strange's Sanctum Sanctorum where the mystical energies converge. Shanzar, the Sorcerer Supreme of that dimension, tired of observing all the inhabitants of that universe began to consider it a burden, so he decided to obliterate them all, only that later he began to feel lonely and therefore attempted to usurp the main universe by passing through it thanks to the possession of the Hulk's body.[1]
