Night Eagle and his tribe adopted Rivesh Mantilax when he was shot down by the American army in 1953. In 1958, he and his tribe killed Mister Dread and the agents who were with him. They saved the Tenth Doctor, Cassie Rice and his grandson, Jimmy Stalkingwolf. Night Eagle took them to meet Rivesh in the cave where he was being looked after. When Colonel Stark found them, they were captured and taken to Area 51. (TV: Dreamland)
