Duke, Roadblock, Rock 'n' Roll and Mainframe have fought their way directly into Cobra's Silent Castle. They are fighting exclusively B.A.T.s and making an easy killing of them. Snake-Eyes comes around the corner and Duke punches him straight away knocking him out. As he hits the ground, it is revealed to be Zartan in disguise. Mainframe asks Duke how he knew it wasn't the real Snake-Eyes, his response, "Snake-Eyes would never leave Scarlett in a tight situation. I just verified it by getting past his defenses to slug him out. No way I could do that to the real Snakester."
