Biography
1998
Impersonating an injured Nasyan, he was taken to the Air Force Academy Hospital with the other Nasyans after Nasya was attacked. After subduing Dr. Jacobs, he searched the hospital with the Hara'kesh. After concluding that Jolinar was not at the hospital, he moved on to Stargate Command, impersonating TSgt. John Adams. After learning that Jolinar had taken Captain Samantha Carter as a host and was being held prisoner, he killed the guards stationed in the brig with Jolinar, and announced her death by the Hara'kesh. He then attempted to move through the Stargate, but Dr. Daniel Jackson recognized him from the hospital. Taking Jackson hostage, he demanded that the Tau'ri open the Stargate and let him through. Teal'c came in and calmly used a Zat'nik'tel on both Jackson and the Ashrak, causing the Ashrak to release Jackson. Teal'c then fired a second shot at the Ashrak, killing him.
