His origin is spoken only in whispers throughout the cosmos, and its truth is shrouded by the mists of time. What is known is that he unleashed a cataclysm that destroyed his entire universe. He alone survived, thrust into the void beyond the omniverse—the Terminus. His ill-fated experiments may have even created the Terminus, or perhaps unleashed its power to spread like a cancer through- out the omniverse. The truth may never be known, since that mortal scientist is long dead; in his place stands Omega, the Lord of the Terminus!
Omega has ruled over his domain for as long as any living race can remember and his goal has always been the same: to expand the Terminus until it engulfs all that is. The barriers separating the many dimensions and layers of reality stand between Omega and his goal. The forces of entropy can only worry at omniversal reality, corroding away bits and pieces here and there, drawing them into the Terminus where they become part of the cosmic flotsam of Omega’s domain.
On occasion, the inhabitants of other dimensions discover the Terminus, to their sorrow, since portals into his realm allow Omega’s forces to raid other worlds and conquer or destroy them. One such world was the birthplace of the Centurion. The infant who would become Earth’s greatest hero was flung across the dimensions through the Terminus to Earth before Omega destroyed his homeworld.
Omega invaded Earth as well, uniting the heroes of Freedom City against him. Earth has only barely managed to repel Omega. His last inva- sion did considerable damage to Freedom City and resulted in the death of the Centurion. Omega was badly damaged in this foray against Earth, and retreated to his throne-world to recover and plot anew.
Impatient, Omega conceived of a scheme to place cosmic weapons in certain key universes to trigger the collapse of the omniverse. He was nearly successful, but a small band of heroes were able to save certain universes and reverse the effects of the collapse. They turned the power of the cosmic weapons against Omega, sending him back into exile. Still, it is only a mat- ter of time before the Lord of the Terminus finds a new means of striking at the only world in the omniverse that has ever managed to thwart him. Omega is destruction incarnate. His ultimate goal is to bring all cre- ation under the sway of the Terminus, watching it spiral down into oblivion. Whether he believes this will grant him freedom from his eternal existence or the godlike power to create a new universe in his own image, no one knows, but it hardly matters. Although he seizes and holds territory to gain new soldiers and resources for his cause, Omega cares nothing for conquest, only the ultimate annihilation of everything. He’s at best annoyed by feeble efforts to stop him, but truly enraged by those who manage to defy him, such as the heroes of Earth.
