Kmada

The Kmada were a civilization native to the galaxy's Delta Quadrant, encountered by the Silver Blood USS Voyager in late 2374 or early 2375. 

History
In the 2370s decade, the Kmada attempted to sabotage Voyager's life support systems with low-frequency theta radiation, but they were thwarted. In the year 2375, the biomimetic copy of Lieutenant Commander Tuvok mentioned the Kmada, along with the N'Kree, when the Silver Bloow crew backtracked their course in search for the cause of the degradation of themselves and their Voyager.
