Role
Linx is forced to make an emergency landing in Cambodia, 1976 after his ship is attacked by a squad of Rutan fighters. There, Linx allies himself with Mao Zedong who offers him shelter in exchange for advanced weapons.

Linx is incredibly intolerant of any interruptions from Mao and his men, and Mao also mocks the Sontaran for his stature, making Linx threaten him in return.
