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.
In Justice League: No Justice, Brainiac brings the heroes and villains of the DC Universe together in order to fight the powerful and ancient Omega Titans. However, Brainiac isn't foolish enough to believe that they can defeat these cosmic gods through traditional means. Instead, his plan is to set the universe back into order by tricking the Omega Titans into going dormant once again.
In order to do this, Brainiac divides the heroes and villains he has collected into four different teams, each one embodying a different kind of energy that represents intelligent life. Each of these groups is also carefully designed to counteract the signature energy of one member of the Omega Titans: Team Wisdom will tackle the Wisdom entity, Team Wonder takes on the Wonder entity, Team Entropy will battle the Entropy entity, and Team Mystery will solve the problem of the Mystery entity.
At first blush, all the members of Team Wisdom are science-based heroes (and Harley Quinn). More than that, Cyborg, the Atom, Robin and the Flash are all intelligent and logical in their own way. and yes, even Harley is super-smart; she is a doctor, after all. Then there's Team Wonder, which is comprised of all magic users of some sort, whether it's through casting spells or using magical weapons. What's more, Wonder Woman, Dr. Fate, Raven, Etrigan and Zatanna all seem to embrace and harness the wonder that life has to offer in some manner.
There is also a team of brawlers in Team Entropy, which includes Batman, Lobo, Lex Luthor, Deathstroke and Beast Boy. All five of these characters possess some form of self-destructive tendencies, making them the perfect teammates. Team Mystery is Superman, Martian Manhunter, Sinestro, Starfire and Starro. These are all space-based characters, yes, but on another level, they embody those questioning their place in the DC Universe.
Even Brainiac is forced to admit, this plan doesn't have a very good chance of working -- but it's the best shot the DC Universe has. The hope is that these teams can use their specific energies together in some way to counteract the Omega Titans, and their own energy signatures. If they can bring balance to the life energies these gods feed off on, perhaps it will cause the Omega Titans to stop their feeding on the universe and slip back into hibernation.
Unfortunately for everyone involved, Brainiac never got a chance to explain how exactly they were going to do all this. They also needed his pinpoint calculations to make it all work in the end, and with his unfortunate death (thanks, m Amanda Waller), he's been removed from the playing field just before the first fight on Colu. Barring a miracle -- or intervention from the as-yet unseen fifth team -- it seems like these four Leagues don't have much of a chance.
