Solomon (Dinosaurs on a Spaceship)

 was a human trader whos ship was intercepted by a Silurian Ark which had crosed his route. He sent out a distress signal and was picked up by the Silurians. He discovered that they were tranporting Dinosaurs upon their Ark and quickly set about taking them for his own. He got his two robots to wake the Silurians from cryo sleep in small groups and then dispatch them into space. He realised later though that the ship had reset its course back to where it came from, Earth, and when The Doctor arrived he realised that he finally had a means of changing course and of repairing his legs, which had been mauled by Velociraptors. The Doctor repaired his legs, but then Solomon betrayed him, demanding for the Egyptian queen Necratiti, otherwise his two Robot Mercenaries would blast the Doctor and his companions with their lasers. The Doctor obliged after Solomon's Robots killed the Triceratops, and Solomon took Necratiti to his small space vessel in a hope to escape, as Earth had locked missiles onto the ship. He failed to demagnetise and needed the Doctor's aid. The Doctor returned but shut down the Robots and placed the homing device in Solomon's ship, so that the missiles would hit it instead. The Doctor took Necrratiti and demagnetised the ship, allowing it to fly out of the Ark. Solomon was then blasted to pieces with his ship.
