History[]
Mayweather held the rank of sergeant in the mid-2150s, and was a member of the MACO contingent assigned to the starship ISS Enterprise. He was made the personal guard of Commander Jonathan Archer after he assisted in Archer's mutiny against Captain Maximilian Forrest. Mayweather was assigned to the assault team that boarded and stole the future starship USS Defiant from Tholian control. He remained loyal to Archer, even as Archer openly declared his desire to seize the Terran Empire for himself. However, sometime before reaching Earth Mayweather was seduced by Lieutenant Hoshi Sato, and played a role in Sato's poisoning of Archer. He stood behind Sato on the bridge of the Defiant as she transmitted her demand for the immediate surrender of the Imperial Starfleet.
Then Charles Tucker III and Major Malcolm Reed interfered and were able to kill both Sato and Mayweather before Imperial Starfleet was able to surrender to them as Sergeant Mayweather was killed by Reed before stepping into the turbolift.
