Lorduke of Zazz
From Tardis Wiki, the free Doctor Who reference
The Lorduke of Zazz was a leading aristrocat of Zazz and brother of Professor Strut. He and Strut were not very close as the Lorduke was a partier whilst Strut was deeply into science. The 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)
