A Green Beetle crackpot theory:

He's the leader of a White Martian resistance movement, who was promised Mars by the Reach if he helped them put Jaime's bug on mode by gaining his trust first.

I just noticed, in the transition of his armor to his "human" disguise, Green Beetle reverts to a Green Martian. He did not need to do that that to change back later on, and Miss Martian didn't need to revert to her natural form back when she was a novice shapeshifter.

Moments earlier, he learned that M'gann was white and posed as green. That could have given him an idea to do the same. By showing a Green Martian form, he hoped to solidify the trust they were starting to get in him.
