Air Force Special Operations officer, who suffers a period of suicidal depression after his son accidentally shoots and kills himself with O'Neil's own pistol. With the humans freed, the remaining team (O’Neil, Kawalsky, and Ferretti) return to Earth while Jackson chooses to stay behind with Sha'uri and the others. O'Neil and Jackson teleport the bomb to Ra's ship, destroying the ship and Ra. O'Neil activates the teleportation system, killing Anubis and allowing Jackson and Sha'uri to escape the ship. Jackson places Sha'uri in the regeneration device, and she recovers, but Ra discovers them and attempts to kill Jackson. Sha'uri is killed, but Jackson takes her body and sneaks aboard Ra's ship using a teleportation system, leaving O'Neil to fight Ra's guard captain, Anubis. The humans outside run out of ammunition and are forced to surrender to the fighter ships' pilots, but the rest of the tribe, seeing that their false gods are only humanoid, rebel against the pilots and overthrow them. O'Neil and his remaining men aid Skaara in overthrowing the remaining overseers and then launch an attack on Ra, who sends out fighter ships against the humans while he orders his ship to depart. Skaara and his friends celebrate, and Skaara draws a sign of victory on a wall, which Jackson recognizes as the final symbol. They flee to nearby caves to hide from Ra. Ra orders the human tribe to watch as he prepares to force Jackson to execute the others to demonstrate his power, but Skaara and his friends create a diversion that allows Jackson, O'Neil, Kawalsky, and Ferretti to escape, while Freeman is killed. Ra tells Jackson that he has found a nuclear bomb O'Neil secretly brought and has used his alien technology to increase its explosive power a hundred-fold, threatening to send it back through the Stargate. Ra places Jackson's body in a sarcophagus-like device that regenerates him. A firefight ensues, Jackson is killed, and the others are captured. Jackson and O'Neil are captured and brought before Ra and his guards, who are revealed to be humanoids when they retract their armored head-pieces. When Jackson, O'Neil, Brown, and Kawalsky return, there is a firefight against Ra's soldiers. That night, Ra's ship lands atop the pyramid structure-his soldiers capture Ferretti and Freeman while killing Porro and Reilly.
During this investigation, Jackson comes across a cartouche containing six of the seven symbols for the Stargate, but the seventh has been broken off. Humans on Earth revolted, overthrew Ra's overseers, and buried the Stargate to prevent its use. Ra enslaved these humans and used the Stargate to bring some of them to Abydos to mine the mineral that is used in the alien technology. Through hidden markings and discussions with the tribe, Jackson learns that Ra is an alien being who came to Earth during the Ancient Egyptian period to possess human bodies to extend his own life. O'Neil befriends Kasuf's teenaged son Skaara and his friends. The tribe's chieftain Kasuf presents Jackson with his daughter Sha'uri as a gift, and although Jackson initially refuses her, he later becomes romantically attached to her. He learns that the tribe sees him and his comrades as emissaries of their god Ra. Jackson figures out that they speak a variant of Ancient Egyptian and is able to communicate with them. O'Neil's group follows and they discover a tribe of humans working to mine a strange mineral. Jackson sees a large animal with a harness, which drags him off when he approaches it to investigate. O'Neil orders Reilly, Porro, Freeman, and Ferretti to stay behind to guard the Stargate. Jackson locates the Stargate's controls but does not find all of the symbols for the return coordinates. They arrive in a pyramid on the arid desert planet of Abydos. Jackson joins O'Neil and his team (Reilly, Porro, Freeman, Brown, Ferretti, and Kawalsky) as they pass through the wormhole.
When all seven are locked in, a wormhole opens, connecting the Stargate with a distant planet. He is then shown the Stargate, which was also discovered by Langford's father, and they use his coordinates to align the Stargate's metal ring with markings along its outside. Jackson determines that the hieroglyphs refer to a "stargate" which uses constellations as spatial coordinates.
