This Ashrak served Anubis by infiltrating the Tau'ri Alpha Site in 2002. When the Tok'ra, escaping from one of Anubis' attack on the Risa system, arrived through the Stargate at the site, the Ashrak attempted to provoke the Tok'ra and Rebel Jaffa into a fight, taking advantage of their prevalent traditional animosity.
Armed with a knife and using a Goa'uld cloaking device to become invisible, he first killed the Tok'ra Ocker, who had been in a confrontation with the Jaffa Artok. After Artok was detained as a suspect, the Ashrak killed him as well. Jaffa Master Bra'tac found the Ashrak's footprints leading away from the base, and the personnel went out hunting for him in groups of three, each made up of a Tau'ri, Tok'ra, and Jaffa. The Ashrak attacked Bra'tac and Malek, dragging Bra'tac into the bushes while Malek ran.
Everyone returned to the camp and took defensive positions while Major Samantha Carter and Malek used a Naquadah generator to emit a high-frequency electromagnetic field which would neutralize the Ashrak's cloak. He attacked the group several times, resulting in confusion and friendly fire. Soon, the electromagnetic field was ready, making the Ashrak visible. He evaded their fire and ran out of range, allowing his cloak to become effective again. He then tried to attack Colonel Jack O'Neill and Malek, but Bra'tac shot him three times with a Staff weapon from behind, killing him. (SG1: "Allegiance")
