Lorduke of Zazz

The Lorduke of Zazz was a leading aristocrat of Zazz and brother of Professor Strut.

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 one of his parties and delivered a present from Strut to the Lorduke. It turned out to be a self-replicating robot that proceeded to wreck the party. The now numerous robots began to then infect the planet. After the Doctor removed the threat, the Lorduke and Strut made up. (DWM: The Gift)
