Calhoun and his crew next appear in the 2008 comic book miniseries "Star Trek: New Frontier: Turnaround". It is revealed that they embarked on a series of successful strikes against the Alliance, during which the mirror Edward Jellico joined Mac's crew. During one such engagement, Soleta is killed, and the "Stinger" finds itself transported through a portal in space into the prime universe. Mac's crew spends the next several weeks making allies, before stealing the "Paradox", an experimental timeship created by Starfleet and the Daystrom Institute, which Mac intends to use to re-write the Mirror Universe's history to prevent the Alliance from taking over his galaxy. His plan is foiled by the crews of the "Excalibur", the "Trident", and Bravo Station, and his counterpart from the prime universe, Captain Calhoun, who cautions him not to try to reshape an entire universe, lest catastrophic results occur. When Calhoun tells him that Admiral Shelby is aboard Bravo Station, which is being pummeled by the "Paradox", Mac surrenders, and the "Paradox" is destroyed. Mac takes his crew back to the Mirror Universe, where the mirror McHenry reveals that he arranged the confrontation between the two Calhouns so that Mac would reach the right conclusion himself, and call off the plan.
