A mirror universe type story where Mirage sees two versions of the same story. In one, he's an autobot with Hound and Prime attacked by starscream, and in the other he's a decepticon leading starscream. He was on the fence when it came time to decide allegences, and apparently his choice is the only difference between these universes. He becomes aware of the two versions by being thrown into some power source that appears to have transdimensional properties (the story was vague to the X-TREEME). No real character insights or plot movement.
there's no time frame for this issue, and it doesn't seem like it'll have any bearing at all on future stories. The art was ok, but all the alt modes were the standard earth ones, which was kinda disappointing. overall, this issue was 'not that great'.
