Can there truly be peace between the Rutan Host and the Sontaran Empire? We find out in the Rutans vs Sontarans finale…First mentioned back in 1970, the conflict between the Sontaran clone warriors and the gelatinous gestalt of the Rutan Host has raged for centuries. In 2025, Big Finish dug into the endless enmity for the four-part audio drama series Sontarans vs Rutans, and this year we’ve been exploring the opposite angle: Rutans vs Sontarans and the fate of one Rutan cruelly split off from the collective. Doctor Who: Rutans vs Sontarans: Peace at Last is available on CD or download to own from Big Finish now. Catch up on our reviews of last year’s Sontarans vs Rutans, and the earlier episodes of Rutans vs Sontarans.
