Biography
Solomon used the two robots to kill the Silurians on the Silurian Ark but was mortally wounded by the dinosaurs on board. The robots took care of him, but were unable to mend his legs. In 2367, Solomon discovered the Eleventh Doctor, Rory Williams and Brian Williams on board. He ordered the robots to take them to him and threatened to have Brian killed if the Doctor didn't mend his legs.
When Solomon took Queen Nefertiti of Egypt, the Doctor deactivated the robots while he bargained for Nefertiti. The robots were presumably destroyed moments later when missiles from India destroyed Solomon's ship with the robots onboard. (TV: Dinosaurs on a Spaceship)
Behind the scenes
The costume of these robots appears to be a modification of the Roboidz from Mission: 2110.
