Patrician was a cyborg whose organic component was a Mar'kak who was in the service of the former Goa'uld System Lord Mars. When Etahy phase shifted his hand into Mars' Mar'kak host, Mars' First Prime Augustus called upon Patrician to become the new host for Mars. Patrician accepted this task, and took Mars' symbiote inside himself which saved Mars from the brink of death. (SG1: "Fall of Rome 1")
