Biography
The Lorduke and Strut were not very close as the Lorduke was a partier whilst Strut was deeply into science. The Sixth Doctor attended his party and delivered a present from Strut to the Lorduke. It turned out to be a Self-Replicating Robot that proceeded to wreck the party. They began to then infect the planet. After the Doctor removed the threat the Lorduke and Strut made up. (DWM: The Gift)
