Twelfth Sontaran Battle Fleet

The Twelfth Sontaran Battle Fleet was a Sontaran battle fleet which invaded Globe Games in early 2009. The Doctor encountered them in his tenth incarnation, where they took part in their own, lethal version of Globe Games. (PROSE: The Sontaran Games)

Vilhol, a "cowardly" Sontaran encountered by the Fourth Doctor and Leela, belonged to the Twelfth Fleet. (AUDIO: The King of Sontar)
