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. 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. Humans on Earth revolted, overthrew Ra's overseers, and buried the Stargate to prevent its use. During this investigation, Jackson comes across a cartouche containing six of the seven symbols for the Stargate, but the seventh has been broken off. That night, Ra's ship lands atop the pyramid structure, and his soldiers capture Ferretti and Freeman while killing Porro and Reilly. When Jackson, O'Neil, Brown, and Kawalsky return, there is a firefight against Ra's soldiers. 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. A firefight ensues, Jackson is killed, and the others are captured. Ra places Jackson's body in a sarcophagus-like device that regenerates him. 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 to Earth. 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. They flee to nearby caves to hide from Ra. Skaara and his friends celebrate, and Skaara draws a sign of victory on a wall, which Jackson recognizes as the final symbol. 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. 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. 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. Jackson places Sha'uri in the regeneration device, and she recovers, but Ra discovers them and
