- You may be looking for Skarr.
Skar was a Sontaran major. When the Doctor's TARDIS was transported to Sontar by the Orb of Fates, Skar trapped the time machine in a stasis field and hoped to be rewarded with the Sontaran Star of Valour for the capture of one of the Sontaran Empire's greatest enemies. However, "Lumpy", the Twelfth Doctor's Dalek companion, helped the Doctor escape. (GAME: The Doctor and the Dalek)
