The replica of Travis Mayweather was a biological replica of Ensign Travis Mayweather of the Enterprise NX-01. Created by the automated repair station in 2152, this facsimile was part of the station's method to abduct humanoids to be part of its computer core. Though convincing on the surface, Doctor Phlox, while in the process of conducting the autopsy, eventually determined it was, in fact, a copy of Mayweather. The giveaway was that genetically altered microbes in a Rigelian fever vaccine Mayweather had had the previous month were all dead, whereas they should have still been alive. These microbes would normally have thrived on the isolytic shock that supposedly killed Mayweather, leading Phlox to conclude the station could not duplicate them. (ENT: "Dead Stop")
Like the real counterpart, this replica was also played by Anthony Montgomery.
