He traveled to Hak'tyl ll with Moloc to crush the Jaffa Rebellion within his ranks. He captured Ishta and tortured her. When Teal'c arrived to save Ishta, he held her at knife point and told Teal'c if he shot her with a Zat'nik'tel she was so weak she would die. Teal'c shot them both anyway and then knocked him unconscious. His master was killed when Stargate Command sent two missiles through a Stargate on his world. (SG1: "Sacrifices")
After the death of his master, Cha'ra became a member of the Free Jaffa Nation and sided with Teal'c and Bra'tac in forming a resistance to the Nation's leader, Gerak, who became a Prior of the Ori and attempted to force the entire Jaffa Nation to become worshipers of the Ori. (SG1: "The Fourth Horseman, Part 2")
Cha'ra was in command of a Ha'tak when he found the Supergate constructed by the Ori and through which the first wave of the Ori's galactic invasion began. He took part in the Battle of P3Y-229 and survived. (SG1: "Camelot")
He was presented at the meeting of Jaffa and he tried to persuade Teal'c to take the position on the Jaffa High Council after that. They were attacked by a bounty hunter who managed to hurt Teal'c although not very seriously. Cha'ra helped Teal'c to prepare the trap for the bounty hunter, he spread the word that Teal'c is still alive but seriously wounded. The bounty hunter was caught by Teal'c in his tent during the next attempt to kill him. Cha'ra and some next Jaffa were prepared outside for a case that something would went wrong. (SG1: "Bounty")
- Cha'ra started out as an enemy, being the First Prime of Moloc. Given his strong belief in Moloc, it is unclear what changed Cha'ra to Teal'c's side, but it's possible that Teal'c proved Moloc's death to him and that was enough to break his belief in the Goa'uld. Despite his initial conflict with Teal'c, Cha'ra seemed to emerge as one of his most trusted friends and allies, even after the Free Jaffa Nation fractured and Teal'c couldn't be sure who was friend and who was foe.
