This unnamed Jaffa was in the service of one of Ba'al's clones. He accompanied his master into the real Ba'al's trap on P3R-112, which was faked as a war meeting. When Ba'al unleashed Symbiote poison, he witnessed every one else die. He remained alive due to his use of the drug Tretonin, which removed his reliance on a Goa'uld symbiote. He was captured by SG-1 and as a result of Ba'al killing everyone, was cooperative and gave up Ba'al's location. (SG1: "Dominion")
