Sibling Rivalry (audio story)

The Doctor, Constance and Flip are stuck on an alien planet in the middle of a civil war. To make matters worse, the Sontarans have invaded. To make matters worse still, two of the dastardly quins - the volatile Clarent and the odious Dellan - are both on the scene...and the Doctor may not survive their furious competition.

Sontaran stories

For the purposes of this list, a "Sontaran story" is one in which one living, authentic Sontaran plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story. For this reason, stories such as The Halloween Apocalypse and Survivors of the Flux are not counted due to the Sontarans' appearance being defined by their importance to following stories. Stories like The End of Time and The Time of the Doctor are also not included due to the Sontarans' appearance being no consequence to the plot of the story. Stories featuring Strax of the Paternoster Gang are only included on the Paternoster Gang story template.
