An American city in Michigan where, in the episode Carpenter Street, Archer and T'Pol travel back to 2004 to stop Xindi-Reptilians from building a bio-weapon.
Detroit is a large city in the American state of Michigan. It is the setting of the Enterprise third-season episode Carpenter Street.
The temporal agent Daniels tells Archer that three Xindi-Reptilians have travelled to Detroit in 2004, and sends him and T'Pol after them. The Reptilians have hired Loomis, a worker at a blood bank, to kidnap people with each of the human blood types, and are using the captives to develop a viral weapon out of sight of their own council.
Archer and T'Pol trace Loomis, find the makeshift laboratory in an abandoned building on Carpenter Street, and prevent the Reptilians from releasing the virus into the city. They return to the 22nd century with the recovered Xindi equipment, leaving Loomis to explain himself to the police.
