Terran (mirror)
From Memory Alpha, the free Star Trek reference.
Terran was the term consistently used to refer to Humans from the mirror universe. (DS9: "Crossover")
On April 5, 2063, a group of Terrans were filled with fear and suspicion when a Vulcan scout ship landed on Earth to initiate first contact. The Terrans slaughtered the Vulcan crew and used the technology within to create the Terran Empire. (ENT: "In a Mirror, Darkly")
This Terran Empire would last almost three centuries until it was overshadowed by the equally vicious aspirations of Klingons, Cardassians, and Bajorans. Although many races in the mirror universe harbored hopes of forming a peaceful alliance to protect civilization, Terrans were rarely found among these rebels due to the wealth and safety afforded by their violent expansionist policies. (TOS: "Mirror, Mirror"; DS9: "Through the Looking Glass", et al.)
