A civilian diplomat and the first commander of the Atlantis expedition
in the Pegasus Galaxy
. An expert in international politics, Dr. Weir is well-known for mediating for the United Nations. When President Henry Hayes
took office in 2004, he placed her in command of the S.G.C.
after moving General George Hammond
to a new position. After standing up to Vice President Kinsey
and his agenda to take control of the Stargate program, Weir led a total review of the Stargate
program over the following months.
Upon the promotion of Jack O'Neill, Weir was transferred to the Ancient outpost of Atlantus, left behind in Antarctica when the city of Atlantis left the planet between five and 10 million years ago. When Daniel Jackson discovered the Stargate address for Atlantis, Weir led the pioneering team through the gate.
Weir's work in diplomacy was referenced by Dr. Jackson when drafting the initial treaty for the Tok'ra-Earth alliance. She speaks five languages, including Russian and Latin (the latter of which is very similar to Ancient). Weir brokered a dozen of the most sensitive international treaties in modern times, and President Hayes used her mediation in North Africa to sway her into her new job.
Weir originally had an aversion to the military, having started her career as a political activist lobbying against government spending on the military. She concluded that, in her own words, the best way to stop the proliferation of weapons is to try and end the need for them. But when she was assigned to the Atlantis expedition, she was in a position of authority over the base's military contingent.
Elizabeth left behind on Earth at least one person very close to her (in addition to her dog, Sedgwick): a man named Simon Wallace. When she managed to return to Earth after a year of being out of contact, she learned that Simon had met someone else and their relationship was over.
Weir returned to Atlantis, where she continued to face difficult ethical and military situations on a regular basis. Though her inclination is always to seek a diplomatic solution to conflict, she has been forced to realize that this usually is not possible when facing ruthless enemies such as the Wraith and the Replicators -- enemies who threaten human existence itself. But she has had more success with others, including the Genii.
After three years as commander of the expedition, during which she also faced questions about her leadership from the I.O.A. (the governing body in charge of the expedition), Dr. Weir was critically injured as Atlantis fled a Replicator satellite weapon. Her brain swelling and her body near death, the team's only choice was to reactivate the Replicator nanites that had infected her a year earlier. Rodney McKay reprogrammed them to heal her body -- but rather than regenerating organic cells, the nanites are now integrated into her system. She is part Replicator.
This allowed Elizabeth to access the Replicators' collective consciousness and lead Sheppard's team on a daring mission to save Atlantis. Elizabeth herself confronted the Replicator leader, Oberoth, distracting him long enough for her people to escape -- though she herself had to remain behind.
When the team encountered a Replicator-made double of Elizabeth several months later, they learned the probable fate of their friend: Oberoth had her executed. The double herself was killed (along with doubles of Sheppard's team) saving them.
