This Jaffa (unknown name) served the Goa'uld Zarin (really a Tok'ra operative) on one of Ba'al's planets. He appeared to be a most loyal subject to Ba'al and Zarin. The planet was one of the planets that The Trust launched rockets carrying symbiote poison through the Stargate, and all Jaffa including this one were killed together with Zarin. (SG1: "Endgame")
