Jask (The Sontaran Ordeal)

Jask was a Sontaran and a member of a Sontaran fleet desperate to participate in the time war. He was sent to Drakkis without armour and guns, which the Eighth Doctor found unusual. He was testing a Sontaran Technology after being sentenced to Ordeal, a punishment for dishonour conduct. He explained to Sarana Teel about the Time Lords acts in the Last Great Time War that changed the timeline on Drakkis. Because of the teleportation experiments he was dying. He managed to get the Sontaran's to hear of Stenk's treachery and get him court martialled before he died.

He temporarily served as the Eighth Doctor's companion. (AUDIO: The Sontaran Ordeal)
