Theron

Theron was an Argolin warlord.

Forty years before the Fourth Doctor arrived on the Leisure Hive, Theron began a campaign of conquest by starting a very brief war with their neighbours, the Foamasi. His ambition all but destroyed the planet and left its people sterile and short-lived. He may have died in the conflict. His helmet hung in the chairman's conference room. (DW: The Leisure Hive)
