Ajack

The Ajacks were miners from Megropolis Three on Pluto. Since the PCM conditioning was not effective in the mines, the Ajacks were more independent than most workers under the control of the Company. Gatherer Hade described the Ajacks as "an arrogant, unsettled lot" and noted that conventional wisdom among the executive grade was that if there was ever to be a rebellion against the Company, it would start among the Ajacks.

Gatherer Hade, Marn and Mandrel all thought that the Fourth Doctor resembled an Ajack, so it would seem that Ajacks had more flamboyant dress sense than other workers on Pluto.
