A Xindi-Reptilian officer sent back to 2004 Detroit to develop a bioweapon from human blood samples, whose operation is tracked down and destroyed by Jonathan Archer and T'Pol.
Damron is a Xindi-Reptilian who appears in the Enterprise episode Carpenter Street, played by Jeffrey Dean Morgan. He leads a small team sent through time to Earth in 2004, out of reach of the Xindi Council.
Working from a derelict factory in Detroit, the Reptilians pay a local man, Loomis, to abduct people of each blood type. From these victims they are engineering a virus intended to wipe out humanity.
The time agent Daniels sends Archer and T'Pol back to investigate. They pose as Loomis's helpers, find the laboratory and fight the Reptilians. Damron tries to release the agent into the city's air, but Archer stops him and the evidence is carried back to the 22nd century.
