The Mondasians were an aggressive and territorial race in the Delta Quadrant. In 2373, Mondasians threatened to destroy Voyager while responding to a distress call from David Bailey. The Mondasians were eventually repelled by the First Federation starship Fesarius. (VOY short story: "Ambassador at Large")

The Mondasians are a reference to the Cybermen from Doctor Who.
