"Janet Fraiser was an extraordinary person. She was kind and funny and talented. Above all, she was courageous."
Major Samantha Carter[src]

Janet Fraiser was Chief Medical Officer of the newly formed Stargate Command. Starting as a captain, she was later promoted to major. She served for seven years up until her death in 2003.

Following her death, Fraiser's role as Chief Medical Officer was temporarily taken over by Dr. Brightman before Dr. Carolyn Lam - the daughter of the SGC's newest commanding officer, Major General Henry Landry - took over the position in 2005.


Background information

Fraiser was once married to a man who discouraged her from joining the United States Air Force. They were no longer together as of 1997 and, apparently, they never had any children. In her seven and a half years at the SGC she became one of the foremost experts on Goa'uld symbiotes, having created a symbiote tank to keep Junior in, and having had opportunities to dissect dead symbiotes. As the Chief Medical Officer of Stargate Command, Dr. Fraiser had the authority to overrule those of any rank whatsoever when it came to medical issue. She used this to get the SGC's main flagship team SG-1, into the infirmary on multiple occasions and ceasing experimental tests on SG team members. Her use of such authority once led SG-1 team leader, Colonel Jack O'Neill to call her a "Napoleonic power monger". (SG1: "Hathor", "Crystal Skull", "Upgrades", "The Curse", "Entity", "Threshold", "Heroes, Part 1")


When Fraiser was first assigned to Stargate Command, she had to deal with the Touched virus to which she, Teal'c, and Dr. Daniel Jackson were immune. After Teal'c managed to secure a blood sample from the Untouched, she realized that she and Daniel were immune because of their use of Antihistamine for allergies. She was then able to synthesize a cure. (SG1: "The Broca Divide")

When the real Colonel Jack O'Neill returned from P3X-562, she determined he was indeed the real O'Neill. (SG1: "Cold Lazarus")

When Colonel Jack O'Neill was infected with nanites on the planet Argos, she discovered the nanites in his blood. While experimenting on the nanites, they almost breached containment and Major General George S. Hammond ordered them destroyed. Fortunately, SG-1 was able to deactivate the nanites in O'Neill and the rest of the Argosians. (SG1: "Brief Candle")

She attempted to remove the Goa'uld symbiote from Teal'c and replace his dependence on it with a drug but was unsuccessful. (SG1: "Bloodlines")

When Dr. Daniel Jackson was presumed dead on the planet Oannes, she believed the rest of SG-1 were suffering from Post-traumatic stress disorder (PTSD) and had Major General George S. Hammond remove them from active duty for a week. When they began to question what they remember, she called Dr. James MacKenzie in to perform a psychiatric examination. (SG1: "Fire and Water")

She assisted Captain Samantha Carter in preventing Hathor from gaining control of Stargate Command when all the men on the base were affected by Hathor's mysterious pink mist. She was wounded in the process and received a medal for her actions. (SG1: "Hathor")

When SG-1 traveled to Hanka and discovered all the Hankan were wiped out by a virus, she and her team were called in to examine SG-1. She cleared them and they went to tag the bodies in hazmat suits. They found a lone survivor named Cassandra. She examined her and found no trace of the virus in her system and she was taken to Earth. Later, Cassandra fell ill and she discovered a bomb in her chest. She and Dr. William Warner tried to remove it but it temporarily stopped her heart. They attempted to send Cassandra back to Hanka but it was determined the closer she got to the Stargate the worse she became. They took her to an abandoned nuclear facility and since she was no longer in proximity to Gate the bomb broke down in her system. Afterwards, she adopted Cassandra. (SG1: "Singularity")


When SG-1 returned from Altair, she performed an exam on Colonel Jack O'Neill and found no heartbeat. She then took his blood and upon seeing that his blood was white, O'Neill used a scalpel to cut into his arm and found he was an Android. (SG1: "Tin Man")

When SG-1 returned from Nasya, she performed an exam on Captain Samantha Carter. She discovered the abrasion in her throat but was unaware it was an entry mark from Jolinar of Malkshur. She later traveled to the Air Force Academy Hospital to help care for the Nasyans. She discovered that one of the Nasyans had incapacitated Dr. Jacobs and escaped the hospital. It was later learned he was an Ashrak named Edrekh. When he succeeded in killing Jolinar, she attempted to save Carter and was successful. (SG1: "In the Line of Duty")

When SG-1 returned from the planet Terella and Dr. Daniel Jackson became ill, she determined he was suffering from withdrawal from the Sarcophagus. While he was recovering, he attacked her and escaped. Fortunately, she was unharmed. (SG1: "Need")

When the Virus Orb opened and one of the spikes pierced Colonel Jack O'Neill's shoulder, she used antibiotics to slow the growth of the A't'trr. Unfortunately, Lt. Graham Simmons was allergic to the antibiotics and became very ill. Luckily, SG-1 was able to convince the A't'trr to go to P4G-881 and he and O'Neill survived. (SG1: "Message in a Bottle")

When SG-1 returned from Chulak with Drey'auc and Rya'c, she examined Rya'c and confirmed there was not a bomb implanted in his chest. Luckily, Drey'auc noticed that his missing teeth had been replaced and Fraiser was able to remove them. She determined it contained a deadly plague that would have killed everyone on Earth. (SG1: "Family")

When Teal'c was bitten by an Infestation fly on Svoriin, she realized he was beyond her help and called in an expert. With the assistance of Captain Samantha Carter and herself, Dr. Timothy Harlow was able to counteract the bug's venom, and with the help of Junior, reverse the effects. (SG1: "Bane")

When Stargate Command was dialed into P3W-451, she was called to the Embarkation room to assist the personnel wounded by an overload. On the way she was detained by Colonel Frank Cromwell, who thought there was an alien incursion. She was released when they ran into Colonel Jack O'Neill. (SG1: "A Matter of Time")

When Colonel Jack O'Neill had the Ancient Repository of knowledge downloaded into his head, she determined his brain was operating at over 90% of its capacity. Later, she observed him building the Power booster device and attempted to take notes but couldn't keep up. (SG1: "The Fifth Race")


When SG-1 captured Apophis, she did her best to keep him alive but without a Sarcophagus his body began to age at a rapid pace. He and his host eventually died and were turned over to Sokar. (SG1: "Serpent's Song")

When Dr. Daniel Jackson switched bodies with Ma'chello, she did everything that she could to keep him alive until they were switched back. (SG1: "Holiday")

When the Pod people became ill, she traveled to PJ2-445 to assist. She was unable to determine the cause so she brought one of the aliens back to Stargate Command. She performed an MRI that caused the alien great pain. Fortunately, Dr. Daniel Jackson and Captain Samantha Carter determined the cause was the damage the Unmanned Aerial Vehicle did to the Moodshroom. (SG1: "One False Step")

When Charlie was sent to Stargate Command by the Central Authority of the Reetou, she performed a complete exam and found that his body was failing from his rapid growth. Since she was unable to help him, he was taken with Jacob Carter and the Tok'ra. (SG1: "Show and Tell")

When the other members of SG-1 were captured by Hathor and Teal'c was found near death, she spent three weeks at his side until he regained consciousness. (SG1: "Out of Mind")

When Teal'c and Cronus were attacked by Nirrti, she was able to save Teal'c but Cronus was beyond her help. Major Samantha Carter was able to heal him with a Goa'uld healing device. (SG1: "Fair Game")

Janet Fraiser 2

When Dr. Daniel Jackson was infected with Ma'chello's Goa'uld killing organisms, she called in Dr. James MacKenzie as she believed he was suffering from schizophrenia. They sent him to a mental facility. When the organism jumped to Teal'c and Daniel's condition improved, she and Major Samantha Carter began work on Ma'chello's Page turning devices. When they activated one, several organisms were released and entered her, Carter, and Colonel Jack O'Neill. Because Carter was a former host to Jolinar of Malkshur, the organism believed it had killed the symbiote and exited her body. She, with the help of Dr. William Warner, was able to guide Carter through the steps of removing the protein marker from her blood and making it safe to inject. Once she completed the process and injected the protein marker, the organisms were killed in her, O'Neill and Teal'c. (SG1: "Legacy")

When Merrin came to Stargate Command to trade Naquadah reactor technology, she performed a blood test and found nanites in her system. She then scanned her brain and found millions of nanites infesting her brain. Merrin explained that the Orbanians use nanites to acquire and share knowledge faster and they cannot harm others. (SG1: "Learning Curve")

When Dr. Samantha Carter and Major Charles Kawalsky arrived in our reality through the Quantum Mirror, she ran blood tests and determined they were who they said they were. (SG1: "Point of View")

A short time later, she patched Captain Kyle Rogers' staff weapon wound. (SG1: "Rules of Engagement")

When SG-1 visited the planet Vyus, they called in Fraiser to try to find a cure for their amnesia. She asked that some of the Vyans go with her to Stargate Command where she could use her more advanced medical equipment to determine the cause of the amnesia. Two Vyans, Orner, Mayris and Ke'ra traveled to the SGC. She found a substance that was blocking certain portions of their brains. With the help of Ke'ra, she was able to dissolve the substance and they regained their memories. (SG1: "Past and Present")

During a Foothold situation at Stargate Command, the Stragoth used the Mimetic imaging device to impersonate her. (SG1: "Foothold")

When Major Samantha Carter was turned into a Za'tarc, Dr. Fraiser attempted to sedate Major Carter so she would not harm herself or others.

(SG1: "Entity")

When Teal'c was captured and brainwashed by Apophis, Bra'tac performed the Rite of M'al Sharran. She disagreed with this and threatened to resign if Teal'c was allowed to die. Fortunately, Teal'c was able to beat his brainwashing and his symbiote was returned to him. (SG1: "Threshold")

When a team of scientists in Antarctica discovered an Ancient women named Ayiana in the ice near the second Stargate, she and SG-1 traveled to the Antarctica base. They thawed the remains and were shocked when they realized she was still alive. A short time later, Dr. Francine Michaels became ill with an Ancient contagion. As the other members of the base started to suffer symptoms including herself, Ayiana used her healing power to heal everyone but Colonel Jack O'Neill as she began to suffer the effects of the disease herself.

Heroes funeral for Janet Fraiser

The Memorial Service of Fraiser.

She was interviewed by Emmett Bregman for his Stargate documentary. After the interview, he asked her to lunch and was clearly flirting with her. The lunch was cut short by a medical emergency. She traveled to P3X-666 with SG-1 and attempted to stabilize Senior Airman Simon Wells during the battle that raged. In the process of treating him, she was hit by an errant staff weapon blast and killed instantly; her final words were, "You hang in there airman." (SG1: "Heroes, Part 1", "Heroes, Part 2")


Fraiser's sacrifice was not in vain as her treatment saved Wells' life. At the memorial service, Major Samantha Carter listed the many lives saved by Fraiser including the whole SG-1 team, Wells, Major Ian Hules and Sgt. Connie Smith. (SG1: "Heroes, Part 1", "Heroes, Part 2")

After the success of the Jaffa rebellion, Teal'c stated that he had personally become uncomfortable using a staff weapon since Janet had been killed by such a weapon. He declared that, in her memory, he would only use a staff weapon if it was completely unavoidable. (SG1: "Two Roads")

Alternate realities

  • In another alternate reality, Janet Fraiser seemingly served as the chief medical officer of the SGA as the Doctor Samantha Carter of her reality referred to her counterpart in our reality as "your Dr. Fraiser" when speaking with Jack. Her fate is unknown, though it is likely that she was killed in the Goa'uld invasion of Cheyenne Mountain in 1999. (SG1: "Point of View")

Alternate timelines

  • In an alternate timeline created when SG-1 were sent almost a century into the future, Janet was the last member of the SGC to evacuate Earth when it fell to a Goa'uld invasion after Earth's allies withdrew their support, intending to remain with General Hammond until he revealed that Cassie had already been evacuated. She served as an opposing figure to the NID's control of the new colony due to her strong ties to SG-1, managing to arrange various short missions back to Earth to offer medical support. She was eventually taken as a host by the Goa'uld Hecate, who served as a leader against the Wraith, and would eventually acquire the service of Rya'c as her First Prime. After SG-1's attempts to change history merely created an alternate timeline, they established that Hecate had been responsible for sending them into the future in the first place, as her Jaffa had rigged the Stargate so that the subsequent wormhole would trap SG-1 in the elliptical orbit of a black hole. During the battle for control of Hecate's Ha'tak, the Goa'uld-Wraith Hybrid Sobek betrayed Hecate and fatally injured Janet's body. Hecate fled Janet, but was crushed by Sobek. The dying Janet was recovered by Carter who was surprised that even after nearly a century as a host, Janet's mind still existed within her body. Janet regained consciousness long enough to tell her old friend she always knew SG-1 would one day return and with a single gesture, offer admonishment, forgivness and friendship. Janet's last act before dying was to warn Carter of Sobek's coming attack. Carter returned Janet's body to Earth on an Al'kesh and Janet's body was buried on her reclaimed home planet. (Stargate SG-1: Apocalypse)

Janet in 2010 in an alternate timeline

  • In an alternate timeline, Janet Fraiser gave Samantha Carter a check up when she was having difficulty conceiving a child. Janet discovered Samantha was unable to have children even though Aschen doctors said she was fine. When they investigated further, they found that almost all of the Earth's population had been sterilized. They informed Daniel Jackson, Teal'c, and Jack O'Neill and together formed a plan to prevent this from ever happening. When the plan was put in motion, Janet traveled to Chulak to let Teal'c know. (SG1: "2010")
