Gerak was previously First Prime of the minor Goa'uld Montu, and with the creation of the Free Jaffa Nation, their first leader. Gerak also became a follower of Origin and subsequently a Prior of the Ori.
- "If I help you, I will die... But I shall die free!"
Within the newly formed Free Jaffa Nation, Gerak was a proponent of distribution of power through military assets instead of through democracy. He was a skilled military leader, and commanded the largest coalition of Free Jaffa within the galaxy. He was invited to Stargate Command by Major General Henry Landry to open up the lines of communication between the two cultures. When a Prior was brought to the SGC by Lt. Colonel Cameron Mitchell, he demanded to speak with him in order to challenge him on his beliefs. He witnessed the Prior set himself on fire. (SG1: "Origin")
During the Battle of Kallana, he commanded three Ha'taks in the battle. He started firing at the force field as soon as he dropped out of hyperspace. He was stopped by Colonel Lionel Pendergast because SG-1 was on the planet. After the Mark IX Nuclear warhead detonated and the force field grew, he demanded that they join in the attack or become a target. When the pieces of the Supergate came through the Stargate, two of his Ha'taks were destroyed and his flagship was damaged. He left but warned the Prometheus that if they stayed their actions would be watched. (SG1: "Beachhead")
He sent Yat'Yir to Earth in search of Ba'al. He first captured Alex Jameson and tortured him for information. He later captured Ba'al and executed him but it was only a clone. (SG1: "Ex Deus Machina")
Gerak was open to the teaching of Origin. When a Prior began visiting him, Gerak believed and eventually chose to follow the Book of Origin. Not only did Gerak accept Origin himself, he felt that to be saved, all Jaffa should be converted to Origin. During sessions of the Jaffa High Council, Gerak attempted to have the Free Jaffa Nation vote to adopt Origin as the official religion of all Jaffa and have it taught to Jaffa children. Gerak's faith was soon tested by the Ori; he was sent to Chulak tasked with the elimination of Jaffa non-believers, including prominent leaders such as Teal'c and Bra'tac. When Gerak arrived, he could not kill his fellow Jaffa and felt that in time they would see the light of Origin. When the Prior discovered this, he disregarded Gerak's objections and questioned the gall of Gerak for defying the Ori. When Gerak asked for forgiveness, the Prior transported his mind to the Ori capital, City of Celestis, while Gerak's physical form remained on Dakara. There, beside the Flames of Enlightenment, the Doci of the Ori transformed Gerak into a Prior. Teal'c and Bra'tac, however, raised an army of Jaffa opposed to Origin, hoping to force Gerak to choose the life of thousands of Jaffa over the Ori. (SG1: "The Fourth Horseman, Part 1", "The Fourth Horseman, Part 2")
Gerak brought a massive fleet of Ha'taks to Chulak, where the rebels were gathering. Teal'c suggested a meeting with Gerak on the surface of Chulak to possibly work out a solution. The meeting site was specifically chosen, as it was a memorial to the Battle of Tazek'sur in which Gerak's father was slain for believing the Goa'uld were false gods. Teal'c managed to convince Gerak that the Ori were no better than the Goa'uld, suggesting that the Jaffa's actions suggested that they were almost afraid to be free. Traveling to Earth, Gerak used his Ori given powers to cure the Tau'ri of the plague that was afflicting them. Although this defiance to the Ori caused an internal self-destruct to activate, Gerak was apparently aware of this trigger and nevertheless chose to aid the SGC regardless, his last words before he spontaneously combusted being to proclaim that he would die free.
