WARNING: The following article contains spoilers for Justice League: No Justice #1 by Scott Snyder, James Tynion IV, Josh Williamson and Francis Manapul, in stores now.
Scott Snyder, James Tynion IV, Joshua Williamson, and Francis Manapul promised that Justice League: No Justice would include new groups of heroes working together in different formations. Brainiac will come to Earth and take the superpowered beings that he needs to put together the most efficient teams possible. We got that in the first issue, but we also learned why these teams were needed.
The creative team called it "moneyballing," as in the act of using data to find value where there was initially believed to be none. In the context of this story, it means Brainiac used mathematical equations to find strengths and compensate for weaknesses. It also meant trying to game the system against the forces of the universe itself. In No Justice, those forces are the Omega Titans, and though they were announced months ago, we've just now learned how this whole Entropy, Wisdom, Mystery and Wonder thing works.
The Legends Come to Life
As Brainiac describes them, the Omega Titans are said to be the oldest myth that has ever spread across the universe. Before civilization started, before language was even invented, there were four brothers who oversaw all life in the universe. As the Martian Manhunter mentions, Mars had its own version of this legend, but what was once mere story has become a deadly reality.
These four brothers were said to embody the four "Fundamental energies of sentient life" referred to as Entropy, Wisdom, Mystery and Wonder. Each Omega Titan represented one of these energies, and the four of them believed their energy was the dominant power of intelligent life. Essentially, each believed that living beings needed to follow certain rules and embody specific characteristics.
In order to decide who was right, the four brothers decided to place a wager; each would plant seeds of their emotional energy, and they would sit back and see which energy was dominant by the end of the universe. Apparently, the Justice League breaking a hole in the Source Wall during the climax of Dark Nights: Metal triggered the Omega Titans to end their game. The problem? Part of the game's finale involves the destruction of entire worlds.
When it comes time for these Omega Titans to tally up their scores, the winner of each world will be allowed to absorb the dominant energy. Since Colu is a planet of scientists and advanced technology, it makes sense that the Wisdom entity was allowed to attack it. Once all the energy is gobbled up, the world is destroyed. "The dying universe is a garden to be eaten by its overseers," is how Brainiac describes the situation.
