Riks

Riks was a Sontaran warrior, serving under the command of General Scox. He reported a human ship crashing onto Sontar’s surface with a Rutan on board, sending out a scouting party to intercept them, though failed to register that the scouts he thought were returning were actually the Rutan Gautier, the 14th Doctor, and Jonski, much to the chagrin of Scox. He later failed to spot Gautier intercepting Jonski and the Doctor as prisoners, giving an evacuation order of the command facility. (AUDIO: The Rutan Stowaway)

On the battlefield, fighting against Rutan invaders, he followed Scox as he attempted to hunt down the Doctor, showing concern when she relayed the Minister of War’s revelation that the entire war had been conducted by a higher power, but he was unable to act on this due to Scox’s bloodthirst. After the Doctor escaped, he silenced Scox’s raging and desperation to capture her – by shooting him in the back. Returning to war, he watched as the Rutan EMP device enveloped the planet, conceding to its power. (AUDIO: Conquest Of Sontar)
