Remember that Injustice: Gods Among Us trailer that strangely had Martian Manhunter randomly appear at the end? We all figured he was going to be revealed as the next DLC character but that didn't happen...until now.
Check out the just released trailer featuring J'onn as he declares he must protect Earth.
Make sure you listen to reason when it comes to Martian Manhunter. When is he coming? We'll have to wait for further details.
