The alien Sil in Vengeance on Varos

Sil (pictured above) is in charge of buying Zeiton-7 for his company, but he's sinister in doing about it. He blackmails the Varos leaders and bullies them into selling their Zeiton-7 ore for a very cheap price, which isn't a good one for the Varos inhabitants.

But the Doctor soon puts things right, and Sil's company is forced to pay a reasonable price for the Zeiton-7 ore, and the Doctor gets enough for the TARDIS and goes on his way, with the Varos people starting a better way of life.
