Jingo Linx
Jingo Linx was a Sontaran Commander in the Fifth Sontaran Battle Group. He was shot down by a Rutan squadron and ended up stranded in 13th century Wessex. Linx allied himself with Irongron, who offered him shelter in exchange for advanced weaponry. Linx abducted scientists from the late 20th century to help him repair his ship. He died when Hal the Archer shot an arrow in his probic vent, and his ship exploded soon afterwards. (DW: The Time Warrior).
Other information
Linx was mentioned briefly by Sarah Jane Smith in 'The Sontaran Experiment', after meeting another Sontaran, Styre, and thinking it was the same. "Linx. A Sontaran! You can't be! You were destroyed in the 13th century, you were blown to smithereens!"
