Sontar (The Infinity Doctors)

In an alternate universe, General Sontar was the Imperator of the Sontaran Empire. He was said to look older than other Sontarans and was important enough to share the name of his people's home planet Sontar. He masterminded the two thousand year war against the Isari. (PROSE: The Infinity Doctors)

Legends tell that he was killed by the Rutan Queen at the beginning of the war with the Rutan Host. Before he died he was the founder of the Grand Strategic Council and after his death they took his place as the leaders of the Sontaran Empire. His DNA was used as the master template of every Sontaran cloning tank. (PROSE: Lords of the Storm)

Behind the scenes

 * The suggestion that the Sontarans derive their name from a single person originated from the FASA Doctor Who Role Playing Game, which claims that they named their planet after him.
