On the distant planet Qward many years ago, a being named Mobius built a sophisticated device called the Mobius Chair. Mobius attempted to view the source of the Anti-Matter Universe, hoping to discover what sparked its creation. What he found was the Anti-Life Equation, an infamous truth the tyrant Darkseid had spent a lifetime trying to locate. The equation merged with Mobius, transforming him into the immensely powerful Anti-Monitor. The Anti-Monitor became a destroyer, traveling from one universe to the next, consuming worlds. He caused the Crisis on Infinite Earths, destroying the Multiverse, an event only a few recall.
