Billions of years ago, in the Pre-Crisis reality, a Maltusian scientist named Krona performed a forbidden experiment in an effort to see the origin of the universe. His irresponsible actions disrupted the process of cosmic creation, resulting in an additional, opposite universe of pure evil. Its own existence corrupted millions of planets in the positive universe.
In all the known worlds of the antimatter universe, its inhabitants glorify evil. Magic doesn't exist in the antimatter universe; Earth's sorcerers did not follow the other heroes to ambush the Anti-Monitor in his headquarters.
The antimatter universe is also the location of the planet Qward. The Weaponers of Qward—devoted adversaries of the Guardians of the Universe—have frequently crossed swords with their dimensional counterparts, the Green Lantern Corps. To help them in their efforts to destroy the Guardians, they have frequently relied upon the aid of a former Corps member, Sinestro. After Sinestro reneged on the Green Lantern Corps, he was banished to this universe where he was popular among the Qwardians, even winning some of their annual contests of cruelty.
The cosmic being known as the Anti-Monitor is also indigenous to the antimatter universe. An analog to the universal Monitor, the Anti-Monitor attempted to destroy all reality with a wave of pure antimatter energy. This ambitious attack culminated in what has become known as the Crisis on Infinite Earths.
During the Crisis, it was discovered that Alexander Luthor, the orphaned son of Earth-Three's Lex Luthor and Lois Lane, was a being comprised of both antimatter and normal matter. As such, he could function equally in both realities without undue stress.
Shortly after the Crisis, it was stated that the Crime Syndicate were Thunderers. but after Zero Hour, the Crime Syndicate of Amerika of the antimatter Earth appeared.
When the Justice League met the Avengers, the antimatter reality was destroyed by Krona. In Syndicate Rules, it is revealed that it was reintegrated anew by sources unknown, but it is not an entirely faithful reintegration. Owlman discovers that the antimatter universe is now only months old.
