Tosk, meaning "The Hunted", were a reptilian race native to the Gamma Quadrant. They did not have personal designations, and 'Tosk' – once one was aware of the role of the Tosk in their native society – pretty much summed up everything about them and their purpose in life. They had the engineering knowledge of how their ships worked and how to repair them. They could also use computers to get information for tactical purposes.
