Dawn of the Guardians of a Universe & the Multiverse

Ten billion years ago, in the positive matter universe that spawned a multiverse, a battle ensued between those who would become protectors and those who would become predators. The Maltusians who migrated from their native world to the planet Oa found their world invaded by strange super-powered humanoid.

These colorful criminals were supervillains, sent into their past to prevent the rogue Oan scientist known as Krona from peering back to the dawn of creation, which would inadvertently unleashed a wave of evil upon his realm, which would also duplicated his own universe an infinite number of times… giving birth to the sinister anti-matter universe. Within that reverse reality, a correlating world known as Qward mirrored that of Oa.

Those seeds of evil were first implanted by the presence of supervillains from Earths One, Two, Four and S, as well as from the universe where the most powerful of their number originated. That being,  Maaldor, had consumed his universe in order to achieve this power, and so his presence in Krona’s laboratory was a building block towards forming the Multiverse. And undoubtedly, the Earth-One Mirror Master and Earth-Two Icicle (who were also in this lab) provided the necessary ingredient with their two distinct vibratory frequencies matching those of their native Earths, which would henceforth link those two worlds.

Additionally, this conflict with both Krona and the villains led the immortal Oans into becoming the Guardians of the Earth-One Universe, which sharing their emerald enemies with neighboring universes to protect them from these same threats.

However, one such threat was the Guardian’s own counterparts the Buddak, who through their intermediary Creator2 attempted to refashion Earth-Two into their universe’s version of Oa. Attempting to do so by unleashing the interconnectivity of that world and Earth-One, they apparently pieced together this symbiotic nature between both parallel planets. Perhaps this was thanks to one of their number… their version of Krona…having mentally connected with Kent “Doctor Fate” Nelson who had experience with this through several cross-dimensional Crisis he dealt with alongside his Justice Society teammates and Justice League allies.
