Group Marshal Stike fought in the Ninth Sontaran Battle Fleet on the Madillon Cluster. The Ninth Sontaran Battle Fleet attacked Space Station Camera and killed nearly all aboard. Stike joined his subordinate Major Varl in Seville where together, they worked with Dastari towards putting together a laboratory where Dastari could work towards perfecting the Kartz-Reimer module, a crude prototype space-time vessel to assist (as ever) in defeating the Rutans in the endless Rutan-Sontaran War. To this end, the two Sontarans had captured the second incarnation of the Doctor and kept him in the cellar of a mansion. In particular, they wished to find about the Doctor's Rassilon Imprimatur and enable the Kartz-Reimer module to work.
