Star Trek/Legion of Super-Heroes #3: Part Three

Captain Kirk and the crew of the Starship: Enterprise have come face to face with Cosmic Boy and the other members of the Legion of Super-Heroes, and each team assumes that the other is responsible for the change in the timeline that landed them in this strange world. But will they find common ground in time to defend themselves from an attack by an elite group of imperial enforcers, some of whom are VERY familiar to the two teams?
