A Delta Quadrant species represented by the swindler Gar, who steals the Doctor's programme from Voyager and sells it to a hospital ship in Critical Care.
The Dralians appear in the Voyager episode Critical Care, where the only member of the species seen is a fast-talking trader named Gar.
In 2377 Gar comes aboard Voyager to do business, replaces the Doctor's mobile emitter with a crude copy and slips away. He sells the stolen programme to the administrator of a Dinaali hospital ship, where the Doctor is appalled to find care rationed according to each patient's value to society.
Janeway meanwhile follows a trail of people Gar has cheated. When he is finally caught he refuses to say where the Doctor is. Tuvok and Neelix frighten and trick him into talking, the latter by serving him a meal that brings on stomach pains and then offering relief in return for the co-ordinates.
