For the prime universe counterpart, please see Dahae.
Dahae was a hypothetical mirror universe version of Lieutenant Dahae in Mirror Universe Encounter, one of the training drill holoprograms presented to the crew of the USS Cerritos in 2381.
In the program, she served aboard the ISS Cerritos, where she helped apprehend Beckett Mariner after it was revealed not to be their "real" Beckett Mariner by Brad Boimler. (LD: "I, Excretus")
