American actor who played five Star Trek roles across four series, most notably the hunted alien Tosk in Deep Space Nine and the Xindi-Reptilian Commander Dolim in Enterprise.
Scott MacDonald is an American actor who became a familiar face under heavy make-up in Star Trek. In 1993 he played both Tosk, the hunted fugitive befriended by O'Brien in the Deep Space Nine episode Captive Pursuit, and the Romulan Subcommander N'Vek in The Next Generation episode Face of the Enemy.
He returned to Deep Space Nine as the Jem'Hadar Goran'Agar in Hippocratic Oath and appeared without prosthetics as Ensign Rollins in Caretaker, the pilot of Voyager.
His longest role came in the third season of Enterprise as Commander Dolim, the ruthless Xindi-Reptilian member of the Xindi Council, who murders Degra and is finally killed by Archer in Zero Hour.
