The Collector


 * For the comic, see The Collector (comic strip).

The Collector was an Usurian who, aided by his Human assistant Gatherer Hade, oversaw operations in Megropolis One on Pluto. The Usurians' Company had, by this time, made Pluto into a world inhabited by Humans who lived in cities lit by artificial suns. The Collector, who in his native form resembled kelp, maintained a humanoid form on Pluto. When the Doctor reprogrammed the Company computer to apply a 2% growth tax, the loss of profits so upset the Collector that he reverted to his native form and was imprisoned. (DW: The Sun Makers)
