John Robson

Robson was the head of a Euro Sea Gas refinery. He refused to believe that the base was under attack by the Weed Creature, stubbornly insisting that the problems the refinery was experiencing was due to a mechanical fault.

He believed the Doctor was a saboteur, and wouldn't listen to Harris's and Van Lutyens's advice to shut off the gas supply.

He fell under the Weed Creature's mental control, but was eventually freed thanks to the Doctor.
