Turner (A Fix with Sontarans)

Turner of the Tenth Sontaran Battle Brigade was one of two Sontarans who planned to destroy the Doctor's TARDIS with a vitrox bomb.

Turner and the Sontaran Nathan encountered the Sixth Doctor, Tegan Jovanka and Gareth Jenkins and recognised Gareth as the Earth Defence Force leader who would defeat them in 2001. He was destroyed by Gareth when he pressed a button on the TARDIS console and shot pressured steam at the Sontarans. (TV: A Fix with Sontarans)

Behind the scenes

 * Group Marshal Nathan and his subordinate, unnamed on-screen but referred to as "Turner" in the script, were a sly reference to the then-current Doctor Who producer John Nathan-Turner. This happened in rehearsal: the script called him Group Marshal Stern. (DWM 104)
