WARNING: The following article contains spoilers for Justice League #14 by Scott Snyder, James Tynion IV, Jim Cheung, Stephen Segovia, Mark Morales, Tomeu Morey, Will Quintana and Tom Napolitano, in stores now.
In the wake of the Source Wall (the physical wall at the edge of the universe) being breached, DC has taken a two-pronged approach to dealing with the fallout. The first wave of investigation and containment obviously fell on the shoulders of the Justice League, but with crises constantly needing their attention, a new incarnation of the Titans was placed in charge of tracking the residual energies.
However, the Titans have faced immense challenges since reforming. Raven has lost her soul-self, Dick Grayson is completely out of commission, and Donna Troy is struggling to accept the reins of leadership. In addition to all this, there's been a cloud of uncertainty lingering over one member, and a retcon in Justice League #14 indicates the level of distrust is only likely to increase.
Placed on the team by her "uncle," the Martian Manhunter, Miss Martian only recently started winning over her teammates. Nightwing didn't appreciate her probing their minds when she connected telepathically for missions, and it became clear she was hiding secrets. But when M'gann finally started warming up to her team during the Drowned Earth crossover, she revealed her deep, dark secret -- she's actually a White Martian, not a Green one like J'onn J'onzz.
The heroes of the DC Universe know all about the civil war on Mars, with the vicious White Martians attempting to wipe out their green counterparts, but J'onn believes M'gann -- a survivor just like him -- can be a force for good. M'gann, though, due to her monstrous appearance and the stigma attached to her race, wanted to ease the transition onto Earth by faking she was J'onn's niece. But while her DC Rebirth history has more or less stuck to old continuity, Justice League #14 introduces a major change to her past by revealing she actually grew up on Thanagar Prime.
The events transpiring on the planet right now, thanks to Hawkgirl aka Shayera Hol, the new Empress of the planet, make this revelation incredibly important, and a bit scary. As J'onn, the other Hawkgirl (Kendra Saunders) and the Green Lantern John Stewart visit the planet to investigate the mysteries of the multiverse and the Totality, he inquires about the Martian Keep, the last Green Martian Elder of the DCU, and someone with knowledge on cosmic events. Thanagar Prime (which moves in between space and time, constantly changing location) offered the Elder refuge but Shayera informs them she died.
As J'onn laments this, he reveals a new piece of information about M'gann -- she actually grew up on this Hawkworld. Kendra, who doesn't trust Shayera at all, is taken aback, but believes J'onn as he vouches for M'gann's character. However, the League discovers the Empress is lying and the Keep is being held prisoner in a vault in the planet's core. A battle erupts with the Savage Hawkman (Katar Hol), an ex-League member, returning to help take his former comrades out, and seemingly confirming Thanagar Prime is officially an enemy of the League.
This leaves us asking whose side M'gann is on, and what role she may have played in the Keep's imprisonment. Did she even meet the Elder? We've seen Miss Martian reporting on certain League and Titans findings to a mysterious person, but we assumed it was a League handler like Batman or J'onn. Now, it appears she could have been a spy infiltrating on behalf of Thanagar Prime.
Shayera's army was ready for J'onn and Co., so one has to wonder if M'gann has been compromised. Either way, it seems she's not just a tool that was planted in the Titans; she's there as part of a higher calling. It remains to be seen if Miss Martian is indeed an agent of Shayera's rising empire, and if that's the case, seeing as the Hawkfolk have the resources to take the League out and maybe even reshape the multiverse, we could be in for yet another interplanetary crisis.
