In the mirror universe, V. Brown was a MACO assigned to the ISS Enterprise (NX-01) in 2155. Brown was one of several Enterprise crew members that left the starship in escape pods when the craft was trapped by Tholian vessels in an energy field and destroyed. The life pods and their occupants, including Brown, were later retrieved by the USS Defiant (NCC-1764), under orders from Commander Jonathan Archer, an officer who had led an assault team there from Enterprise.
Later, Brown was one of three MACOs who helped Archer and Major Reed search the Defiant for Slar, a member of the reptilian Gorn species. When Archer and Reed separated, Brown was one of two MACOs who stayed with Reed while B. Scott left with Archer. Reed led his team of MACOs to a bio-sign, only to find a communicator that had been set to emit the signal. However, Slar had also set an explosive device on the ceiling above the communicator. Realizing the Gorn's trap, Reed alerted the other two officers, but they were too late to escape and the bomb detonated. Archer later found Brown lying unconscious on the deck with his face extremely bloodied. (ENT: "In a Mirror, Darkly, Part II")
- Brown was either injured or killed in the explosion and his final fate is unknown.
- It is unknown whether V. Brown exists in our universe or the first name of either officer.
