The question on everyone's mind is who is the man behind John Jones. Our Martian Man-hunter was working for someone, and logic would dictate he was a member of the DC universe. this leaves but two options; either he was a member of the JSA or he is another very salient DC character. The easiest answer would of course be Hawkman, not only is he a JSA member and thus aware of checkmate and their somewhat nefarious tendencies, but he is also played by an established silver screen actor with a scifi history. He also posses an established history of organizational ability in that he assembled the first league, but there is another DC character who would be far more interesting as a mastermind or even 'black knight'.
Not only does he posses a preexisting lore with fighting this particular government sponsored wackjob, but he also has the money, the clout and the pure hero badassness to pull this off. I personally have been wondering where he has been for about five seasons now and if 'he' has finally appeared we know that we are about an episode away from the red and blue. My issue is are we ready for Batman when Superman can't even fly, this is why I reluctantly suspect Hawkman or another JSA character.
