Jaffa of fairly high standing in service to Apophis. Fro'tak had been in the service of Bra'tac when he was younger and was believed to be trustworthy. He maintained a wealthy home in the city on Chulak.
Fro'tak worked as a scribe in the Hall of Recording within the west wing of Apophis's palace, less than two hundred paces from where Teal'c's son Rya'c had been held by the System Lord. He was key in aiding SG-1, Teal'c and Bra'tac in an attempt to pull Ry'ac from Apophis's control.
Fro'tak had married Drey'auc, Teal'c's former wife, but Drey'auc (who did not actually love him) gave vows she could not keep. With the arrival of Teal'c, Drey'auc showed her love for him, and Fro'tak, in angered betrayal, ran to tell the guards of Apophis that the traitors were on Chulak. O'Neill, having anticipated his change of heart, used a zat'ni'katel to kill him and disintegrate his body.
Family - Fro'tak, who took Drey'auc and Ry'ac into his care, is betrayed by the presence of Drey'auc's former love and his old friend, Teal'c, then travels to expose Teal'c and his supporters.
