BIOGRAPHY

An ancient Goa'uld, he was imprisoned along with his queen Isis in statis jars by Seth. Osiris remained trapped for several thousand years until his jar was found by an archaeological expedition. He was freed by Sarah Gardner who became his new host. Secretly, Osiris began collecting information on Isis while masquerading as Sarah, but when her plan was found out by Daniel Jackson, she was forced to escape in a ship buried in Egypt near the temple where the statis jars had been found.

She spent several months exploiting the power vacuums created by the defeated Goa'uld System Lords Heru-ur, Cronos and Sokar to create a sizeable army for herself for her goals of conquest. She was found by Zipacna and offered a position of power among those who served Anubis. Knowing Anubis' reputation for a fact since both had been acquainted in the past, she accepted servitude under Anubis and went to represent him at the summit of the System Lords where the System Lords were negotiating an alliance against Anubis.

Upon her arrival, she presented an ultimatum to the present System Lords in order for them to vote Anubis back among them. Most(save Yu) reluctantly voted Anubis back at the promise of a plan to destroy Earth. Osiris stabbed Yu at the conference when a misunderstanding broke out when Daniel Jackson tried to kidnap Osiris and to have him removed from his host, Sarah.

Several months after the summit, Osiris attacked a planet under the Protected Planets' Treaty and managed to destroy Thor's ship(and capture Thor in the process) by using new technology developed by Anubis. She was searching for a secret Asgard laboratory on the planet that had valuable information to the Asgard. SG-1 intervened, managed to rescue Thor and Heimdall(the operator of the laboratory) and escaped with the help of three Asgard O'Neill-class ships just as Anubis' mothership closed in.
