Commander of an alien vessel encountered by the NX-01 in 2153, Tret's people had lost tens of millions to the Loque'eque virus in 2093. As a result he was fanatically determined to wipe out any trace of the virus, including all those infected with it. He attempted to destroy the NX-01 when several of the crew were infected, but relented when Phlox managed to devise a successful cure. [1]
