Bra'tac of Chulak is Teal'c of Chulak's former Jaffa Master who still is his ongoing teacher and friend. Teal'c also considers him to be like a father for him, and Bra'tac is known to be an honorable and decent man. He was previously First Prime of the Goa'ulds Apophis and Klorel before finally defecting and officially joining the Alliance of Nations, he is one of the founding members of the Tau'ri-Jaffa Alliance. Originally untrusting of the Tau'ri, notably SG-1, Bra'tac has since gone on to become one of the SGC's closest allies, often assisting SG-1 in various missions while providing the SGC with knowledge of the Goa'uld.
