Qward was ruled by their universe's version of the Monitor (who would come to be called the Anti-Monitor by Earth's superheroes). It was this entity that created the organization of warriors known as the Weaponers of Qward within the race known as Qwardians. The Qwardians are the anti-matter counterparts to the Guardians of the Universe. Although the Anti-Monitor was defeated and imprisoned by his counterpart from the positive-matter universe, the Weaponers themselves continued to rule their world. In one of the earliest JLA/JSA crossovers, a being from the anti-matter Universe called Anti-Matter Man appeared, who was an explorer who was travelling through warp-space towards Earth-1 and 2, apparently not aware that contact with them would make them explode. This being was tens of metres high with blue skin and had some resistance to magic, along with strange powers which could warp positive-matter. He was sent back to his universe using shock-waves caused by the Spectre and Atom.
