Adrian Conrad was a businessman and owner of Zeditron Industries.



A wealthy business owner determined to beat Berchart's syndrome, a rare, incurable illness by any means necessary. Conrad orchestrated the capture of Major Samantha Carter after learning that she had once been the host to a Goa'uld symbiote. Although determined to learn the creatures' regenerative secrets in order to save his life, Conrad was still not prepared to kill her for medical research to benefit himself. His assistant, Diana Mendez, however, decided to have Carter killed when Adrian fell unconscious and the scientists believed a dissection of Carter's brain was necessary. The Russians had captured a Jaffa during their short-lived Stargate program, which was procured for Conrad by Harold Maybourne. The symbiote inside the Jaffa was believed to be one of Cronus' offspring (although it was birthed by a Goa'uld queen who belonged to Nirrti), and Conrad's corporation purchased the creature to study it. Conrad believed that once the creature was within him, it could be removed after he was healed, and decided to go through the procedure after his illness reached its apex. The Goa'uld was successfully implanted—and Mendez allowed it to go free after it convinced her that Conrad was in control when in actuality, the Goa'uld had taken over Conrad's body while presumably suppressing Conrad's own consciousness.

The Goa'uld possessed Adrian Conrad.

The creature immediately demanded passage off the planet, but was intercepted by Colonel Frank Simmons, who transferred him to an NID safehouse near Minot, North Dakota. (SG1: "Desperate Measures")


Conrad's location was discovered by Colonel Jack O'Neill and Maybourne, who transferred the Goa'uld-possessed Conrad into the custody of the federal government. (SG1: "48 Hours")

Conrad later died when his symbiote attempted to escape with the hijacked Prometheus, trying to commandeer the ship from Colonel Frank Simmons and his rogue NID team while in hyperspace. Simmons, however, shot him at point blank range, and the Goa'uld transferred into him instead, killing Conrad for good. The symbiote was killed soon after, when Colonel Jack O'Neill sent the infested Simmons into the vacuum of space. (SG1: "Prometheus")
